Ducommun Incorporated reports higher first-quarter 2026 results while reflecting previously disclosed financial statement restatements. Net revenues rose to $209.0 million from $192.5 million a year earlier, driven by growth in both Electronic Systems and Structural Systems, particularly in military, space and commercial aerospace markets.
Net income increased to $9.9 million versus $1.4 million, with diluted earnings per share improving to $0.64. Operating income expanded to $15.7 million, aided by lower selling, general and administrative expenses and the absence of restructuring charges versus the prior-year period.
The company ended the quarter with $39.1 million in cash, net cash provided by operating activities of $11.2 million, and total debt of $303.8 million. Contract assets were $249.2 million and contract liabilities $52.5 million, with remaining performance obligations of $1,073.7 million. Management also details the 2025 restatement tied mainly to accelerated stock-based compensation expense and related control weaknesses.
Ducommun Incorporated reported a strong start to 2026 with record first-quarter revenue and sharply higher profitability. Net revenues for Q1 2026 reached $209.0 million, up about 9% from Q1 2025, driven by commercial aerospace and defense demand.
Gross margin improved to 26.9%, while net income jumped to $9.9 million, or $0.64 per diluted share, compared with $1.4 million, or $0.09 per share, a year earlier. Adjusted EBITDA rose to $35.4 million, or 16.9% of revenue. Both Electronic Systems and Structural Systems segments delivered higher revenue and operating income, and cash from operations increased to $11.2 million from $0.8 million.
Ducommun Incorporated is filing an amended annual report to restate prior-period financial statements after identifying a stock-based compensation timing error and related control issues. The non-cash error affected the timing of expense recognition and certain balance sheet accounts but did not change net revenues, gross margin or operating cash flow. The company is restating audited results for 2024 and 2025 and several 2024–2025 quarters, and also correcting other previously immaterial period misclassifications.
Management concluded there was a material weakness in internal control over financial reporting, so internal controls and disclosure controls were deemed ineffective for several 2024–2025 dates, and prior management and auditor reports on controls and financials should no longer be relied upon. Ducommun remains focused on aerospace and defense, which provided 96% of 2025 net revenues, with backlog of $1,202.9 million and remaining performance obligations of $1,106.0 million as of December 31, 2025.
Ducommun Inc. director Mark A. Caylor filed an initial Form 3 reporting his beneficial ownership in the company. The filing shows he holds no shares of Common Stock directly as of May 4, 2026. This is a routine disclosure for a newly reporting insider and does not reflect any recent stock purchase or sale.
Ducommun Incorporated appointed Mark A. Caylor to its Board of Directors as a Class II director, effective immediately, with a term running until the 2029 annual stockholder meeting. He will also serve on the Board’s Audit Committee.
Non-employee directors receive an $85,000 annual cash retainer, plus restricted stock units valued at $160,000, committee retainers ranging from $5,000 to $12,500, additional chair retainers of $7,500 to $17,500, and a $32,000 retainer for the lead independent director. Caylor will receive proportionate 2026 amounts and the standard indemnification agreement. The company highlights his more than 35 years of aerospace and defense experience, including senior leadership roles at Northrop Grumman, to support its VISION 2027 Strategy and ongoing board refresh, under which six new directors have joined in the past five years.
Ducommun Incorporated identified an error in how it accounted for stock-based compensation after changing retirement provisions in April 2024. The mistake affects the timing of expense recognition for retirement-eligible employees and led management to conclude several previously issued financial statements should no longer be relied upon.
The company will restate affected periods by amending its 2025 annual report and has determined the issue caused a material weakness in internal control over financial reporting, making its controls ineffective as of multiple 2024 and 2025 dates. The error is non-cash and does not affect net revenues, gross margin, operating cash flow, or compliance with debt covenants.
Ducommun expects incremental stock-based compensation expense of about $5.0–$6.0 million in Q1 2026 versus prior expectations, but no change to full-year 2026 stock-based compensation. The Compensation Committee expects to claw back roughly $5.0–$6.0 million of incentive pay for 2024 and 2025. The company plans to file an amended 2025 annual report and complete the restatement on or before May 8, 2026.
Ducommun Incorporated reported the results of its 2026 Annual Meeting of Shareholders held on April 29, 2026. Shareholders elected Stephen G. Oswald and Samara A.

Dimensional Fund Advisors filed Amendment No. 20 to Schedule 13G/A reporting beneficial ownership of 512,167 shares of Ducommun Inc Common Stock, representing 3.4% of the class.
The filing states Dimensional acts as adviser to multiple funds that own these shares, that the securities are owned by the Funds, and that Dimensional disclaims beneficial ownership. The report shows sole voting power for 498,656 shares and sole dispositive power for 512,167. The filing is signed by the Global Chief Compliance Officer on 04/09/2026.
Ducommun Inc files Amendment No. 1 to a Schedule 13G/A reporting zero beneficial ownership. The filing states 0% ownership and 0 shares beneficially owned as of the disclosure, reflecting an internal disaggregation by The Vanguard Group following an organizational realignment.
The amendment explains that certain Vanguard subsidiaries will report separately in reliance on SEC Release No. 34-39538; the filing is signed by Ashley Grim on 03/26/2026.
Ducommun Incorporated is asking shareholders to vote at its virtual 2026 Annual Meeting on April 29, 2026 on four items: electing two directors, an advisory say-on-pay vote, ratifying PricewaterhouseCoopers as auditor, and approving an amended 2024 Stock Incentive Plan.
Management highlights 2025 as a strong year under the VISION 2027 strategy, with stock up 49%, record revenue of $824.7 million, an approximately 180 bps gross margin increase and market capitalization up over 50% versus the prior year. Three-year total shareholder return ranked in the 78th percentile of the Russell 2000.
The Board stresses governance and refreshment: seven of eight current directors are independent, all key committees are fully independent, a Lead Independent Director role is in place and five new directors have joined since 2021, reducing average tenure. The proxy also emphasizes pay-for-performance compensation, stringent stock ownership guidelines, and extensive shareholder engagement.
Ducommun devotes significant space to environmental, safety and social initiatives. Lost time incident rate fell to zero and total recordable incident rate dropped about 72–92% over recent years. Since 2019, Scope 1 emissions are down 33% and Scope 2 down 55%, with 39% of energy from renewables and initial TCFD-aligned climate reporting in place.
