First Quarter 2024 Results

Record Start to the Year for both Q1 Revenue and Gross Margins

SANTA ANA, CALIFORNIA (May 8, 2024) – Ducommun Incorporated (NYSE: DCO) (“Ducommun” or the “Company”) today reported results for its first quarter ended March 30, 2024.

First Quarter 2024 Recap

•Net revenue was $190.8 million, an increase of 5.3% over Q1 2023

•Net income of $6.8 million, or $0.46 per diluted share, or 3.6% of revenue, up 70 bps year-over-year

•Non-GAAP adjusted net income of $10.4 million, or $0.70 per diluted share

•Gross margin of 24.6%, year-over-year growth of 430 bps

•Adjusted EBITDA of $27.4 million, or 14.4% of revenue, up 170 bps year-over-year

“Q1 was an outstanding quarter and a great start to the year for Ducommun, as we grew our topline year-over-year, led by continued strength in Commercial Aerospace at both Boeing and Airbus while also delivering our strongest quarterly gross margin ever,” said Stephen G. Oswald, chairman, president and chief executive officer. “We achieved a new first quarter revenue record of $190.8 million up 5% over Q1 2023, with solid demand for both narrow-body and wide-body aircraft. The Company's gross margin was another real highlight, expanding 430 bps year-over-year from 20.3% to 24.6% as we saw improved operating performance, continued growth from our higher margin engineered products businesses along with some initial benefits from our on-going restructuring program.

“In December 2022, we laid out our Vision 2027 Plan to investors and as we begin year two in 2024, it continues to take shape in a very positive way. Coming off a very good 2023 with record revenue, we continued that again for Ducommun's first quarter with another record performance. As we execute against our 2027 Vision Plan, we are highly encouraged with the results, I also could not be more pleased with strong margin expansion across the board with net income, Adjusted EBITDA, gross margin and operating margin all increasing considerably in the quarter. We continue to see traction with Vision 2027 and I fully believe it will continue to deliver significant value to our shareholders now and in the future. In addition, our operating team has done a very good job navigating through the recent Commercial Aerospace challenges and continues to deliver strong results against a difficult backdrop. As the backdrop continues to improve, we expect our path to Vision 2027 targets to accelerate.

As we move through our 175th year in business, we are excited about continuing to execute on our stated 2027 strategy, lots of runway ahead.”

First Quarter Results

Net revenue for the first quarter of 2024 was $190.8 million compared to $181.2 million for the first quarter of 2023. The year-over-year increase of 5.3% was primarily due to the following:

•$8.1 million higher revenue in the Company’s commercial aerospace end-use markets due to higher rates on rotary-wing aircraft and both single-aisle and twin-aisle aircraft platforms, partially offset by lower rates on other commercial aerospace business; and

•$1.3 million higher revenue in the Company’s military and space end-use markets due to higher rates on naval and rotary-wing aircraft platforms, partially offset by lower rates on legacy fixed-wing aircraft platforms.

Net income for the first quarter of 2024 was $6.8 million, or 3.6% of revenue, or $0.46 per diluted share, compared to $5.2 million, or 2.9% revenue, or $0.42 per diluted share, for the first quarter of 2023. This reflects higher gross profit of $10.2 million and lower restructuring charges of $2.8 million, partially offset by higher selling, general and administrative (“SG&A”) expenses of $6.7 million and lower other income of $3.9 million. The higher SG&A expenses were primarily due to BLR Aerospace (“BLR”) SG&A expenses of $5.5 million (82% of the total increase in SG&A expenses) which did not exist in the prior year period as the acquisition of BLR was completed during Q2 2023.

Gross profit for the first quarter of 2024 was $46.9 million, or 24.6% of revenue, compared to gross profit of $36.8 million, or 20.3% of revenue, for the first quarter of 2023. The increase in gross profit as a percentage of net revenue year-over-year was primarily due to favorable product mix, pricing actions, higher manufacturing volume and some initial benefits from our on-going restructuring program.

Operating income for the first quarter of 2024 was $12.6 million, or 6.6% of revenue, compared to $6.4 million, or 3.5% of revenue, in the comparable period last year. The year-over-year increase of $6.3 million was primarily due to higher gross profit and lower restructuring charges, partially offset by higher SG&A expenses, which was noted above. Non-GAAP adjusted operating income for the first quarter of 2024 was $17.1 million, or 9.0% of revenue, compared to $13.6 million, or 7.5% of revenue, in the comparable period last year. The year-over-year increase was primarily due to favorable product mix, pricing actions, higher manufacturing volume and initial benefits from our on-going restructuring program, partially offset by higher SG&A expenses, mainly due to the addition of the BLR acquisition.

Adjusted EBITDA for the first quarter of 2024 was $27.4 million, or 14.4% of revenue, compared to $23.1 million, or 12.7% of revenue, for the comparable period in 2023.

Interest expense for the first quarter of 2024 was $3.9 million compared to $4.2 million in the comparable period of 2023. The year-over-year decrease was primarily due to the benefit from the interest rate swaps which became effective on January 1, 2024, partially offset by a higher debt balance in the first quarter of 2024.

During the first quarter of 2024, the net cash used in operations was $1.6 million compared to a net cash used in operations of $18.9 million during the first quarter of 2023. The lower net cash used in operations during the first quarter of 2024 was primarily due to a smaller increase in inventories and higher contract liabilities (resulting from driving more progress payments from customers), partially offset by higher contract assets.

Business Segment Information

Electronic Systems

Electronic Systems segment net revenue for the quarter ended March 30, 2024 was $107.5 million, compared to $105.6 million for the first quarter of 2023. The year-over-year increase was primarily due to the following:

•$2.4 million higher revenue in the Company’s commercial aerospace end-use markets due to higher rates on large aircraft platforms; partially offset by

•$0.8 million lower revenue within the Company’s military and space end-use markets due to lower rates on fixed-wing aircraft platforms, partially offset by higher rates on various missile and naval platforms.

Electronic Systems segment operating income for the quarter ended March 30, 2024 was $19.0 million, or 17.6% of revenue, compared to $10.0 million, or 9.5% of revenue, for the comparable quarter in 2023. The year-over-year increase of $9.0 million was primarily due to higher manufacturing volume, favorable product mix, and lower restructuring charges. Non-GAAP adjusted operating income for the first quarter of 2024 was $19.8 million, or 18.4% of revenue, compared to $12.3 million, or 11.6% of revenue, in the comparable period last year.

Structural Systems

Structural Systems segment net revenue for the quarter ended March 30, 2024 was $83.3 million, compared to $75.6 million for the first quarter of 2023. The year-over-year increase was primarily due to the following:

•$5.7 million higher revenue within the Company’s commercial aerospace end-use markets due to higher rates on rotary-wing and large aircraft platforms, partially offset by lower rates on other commercial platforms; and

•$2.1 million higher revenue within the Company’s military and space end-use markets due to higher rates on fixed-wing and rotary-wing platforms, partially offset by lower rates on missile platforms.

Structural Systems segment operating income for the quarter ended March 30, 2024 was $2.9 million, or 3.4% of revenue, compared to $4.7 million, or 6.3% of revenue, for the comparable quarter in 2023. The year-over-year decrease of $1.9 million was primarily due to higher costs associated with the wind down of our Monrovia performance center, partially offset by favorable product mix and lower restructuring charges. Non-GAAP adjusted

operating income for the first quarter of 2024 was $6.5 million, or 7.8% of revenue, compared to $9.7 million, or 12.9% of revenue, in the comparable period last year.

CG&A expenses for the first quarter of 2024 were $9.2 million, or 4.8% of total Company revenue, compared to $8.4 million, or 4.6% of total Company revenue, for the comparable quarter in the prior year. The year-over-year increase in CG&A expenses was primarily due to higher stock-based compensation expense of $1.0 million and higher compensation and benefits costs of $0.6 million, partially offset by lower professional services fees of $0.8 million.

You should not put undue reliance on any forward-looking statements. You should understand that many important factors, including those discussed herein, could cause the Company’s results to differ materially from those expressed or suggested in any forward-looking statement. Except as required by law, the Company does not undertake any obligation to update or revise these forward-looking statements to reflect new information or events or circumstances that occur after the date of this news release, May 8, 2024, or to reflect the occurrence of unanticipated events or otherwise. Readers are advised to review the Company’s filings with the Securities and Exchange Commission (which are available from the SEC’s EDGAR database at www.sec.gov).

Note Regarding Non-GAAP Financial Information

This release contains non-GAAP financial measures, including Adjusted EBITDA (which excludes interest expense, income tax expense, depreciation, amortization, stock-based compensation expense, restructuring charges, Guaymas fire related expenses, insurance recoveries related to loss on operating assets, and inventory purchase accounting adjustments), including as a percentage of revenue, non-GAAP operating income, including as a percentage of net revenues, non-GAAP earnings, non-GAAP earnings per share, 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 potential revenue and is based on 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 is 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 several programs to a greater extent than the Company’s net revenues. As a result of these factors, trends in the Company’s overall level of backlog may not be indicative of trends in the Company’s future net revenues.
