# **Message to our Shareholders** 
**Stephen G. Oswald**

Chairman, President and

Chief Executive Officer

Dear Fellow Shareholders:

I am happy to invite you to the 2026 Ducommun Incorporated Annual Meeting of Shareholders (the "Annual Meeting").

Once again, our Annual Meeting will be conducted online through a live audiocast, which is often referred to as a "virtual meeting" of shareholders. The digital format will allow shareholders to participate conveniently and effectively from any location with access to the Internet. We intend to hold our virtual Annual Meeting in a manner that affords shareholders the same general rights and opportunities to participate, to the extent possible, as they would have at an in-person meeting.

The Annual Meeting will be held on Wednesday, April 29, 2026 at 9:00 a.m., Pacific Time and you will be able to attend online, vote your shares electronically, and submit your questions by visiting www.virtualshareholdermeeting.com/DCO2026 and entering your control number. You will not be able to attend the Annual Meeting in person. The attached Notice of Annual Meeting of Shareholders and Proxy Statement discuss the items scheduled for a vote by shareholders at the meeting.

The Securities and Exchange Commission's rules allow companies to furnish proxy materials to their shareholders over the Internet. As a result, most shareholders will receive a notice in the mail regarding the availability of proxy materials for the Annual Meeting on the Internet instead of paper copies of those materials. The notice contains instructions on how to access the proxy materials over the Internet and how shareholders can receive paper copies of the proxy materials, including a proxy or voting instruction form. This process expedites shareholders' receipt of proxy materials and lowers the cost of the Annual Meeting. The Board of Directors has fixed the close of business on March 2, 2026, as the record date for the determination of shareholders entitled to receive notice of and to vote at the Annual Meeting.

In 2025, Ducommun ("DCO") stock gained 49% which was great to see as DCO's VISION 2027 strategy and performance was recognized. The Company completed the third year of its VISION 2027 game plan in 2025 and continued to build on its outstanding track record of strong operational leadership and progress since its inception at the beginning of 2023. This included increasing the revenue percentage of engineered product and aftermarket content, which reached 23% in 2025, up from 15% in 2022, consolidating the Company's rooftop footprint in contract manufacturing by completing the sale of its Berryville, AR facility and actively marketing the Monrovia, CA facility, continuing its targeted acquisition program, executing our offloading strategy with defense primes and high growth segments of the defense budget, driving value-added pricing, and expanding content on key commercial aerospace platforms. The Company also reached record revenues at $824.7M, increased margins across the board on an adjusted basis and achieved a three-year total shareholder return in the 78<sup>th</sup> percentile of the Russell 2000 Index. Mr. Richard Baldridge will also be retiring as of this year's Annual Meeting and on behalf of all shareholders and board members, I want to convey our gratitude for his many years of contributions and service to the Board and Ducommun.

Finally, it is important that your shares be represented and voted at the Annual Meeting. Whether or not you plan to attend the Annual Meeting, please sign, date and return the enclosed proxy card or vote by telephone or using the Internet as instructed on the enclosed proxy materials. Please vote your shares as soon as possible as your participation is important.

Sincerely,

### **2025 Performance and Ten-Year Highlights** 
Results for the year ended December 31, 2025 serve as demonstrated evidence that the Company's VISION 2027 Strategy is working as intended. We successfully increased the revenue percentage of engineered products and aftermarket content, which reached 23% in 2025, up from 15% in 2022, consolidated our rooftop footprint in contract manufacturing by completing the sale of our Berryville, AR facility, continued our targeted acquisition program, executed our offloading strategy with defense primes and high growth segments of the defense budget, drove value-added pricing, and expanded content on key commercial aerospace platforms. As a result, Ducommun attained a 49% increase in stock price between December 31<sup>st</sup> of 2024 and 2025, increased its market capitalization by over 50% compared to the prior year, and for the third consecutive year attained all-time high revenues of $824.7 million, exceeding $800 million for the first time, and an impressive 180 bps increase in gross margin percentage over the prior year, all of which are expected to accelerate the achievement of our strategic goals and objectives under the VISION 2027 game plan for investors. Ducommun's Board and management team continue to have a high conviction in the VISION 2027 Strategy and its financial goals and believe that the many catalysts ahead present a unique value creation opportunity for shareholders. For example, Ducommun has had 19 consecutive quarters of year-over-year growth in revenue, despite facing continued headwinds in its commercial aerospace business. 2025 also marked the eighth full year since Mr. Oswald, our Chairman, President and CEO, joined Ducommun, over which time the Company's market capitalization has nearly quadrupled. The graphs below depict the significant positive impact his leadership has had on our performance along several key metrics:

### **Environmental and Safety Highlights** 
Ducommun has continued to make excellent progress with our Corporate Environmental Responsibility program in 2025. Ducommun's lost time incident rate<sup>(4)</sup> ("LTIR") dropped to zero, a 100% decrease since 2022, which is a remarkable achievement, and our total recordable incident rate<sup>(5)</sup> ("TRIR") decreased by approximately 72% during that same time frame, both reflective of world-class performance:

Over the past four years Ducommun has decreased its Scope 1 greenhouse gas emissions by 17% through a combination of energy efficiency upgrades, boiler conversions and process optimization initiatives. The Company also achieved a 55% reduction in its Scope 2 greenhouse gas emissions over the same time frame by procuring energy from renewable sources, converting to LED lighting and implementing HVAC upgrades. Moreover, the Company has reduced its Scope 3 emissions by 20% since 2023 by lowering the volume of waste generated and transported for off-site disposal. Ducommun now obtains 39% of its energy needs from renewable sources:

&nbsp;&nbsp;&nbsp;&nbsp;*(4)* *Lost time incidents are defined as incidents that resulted in days away from work. This measure is similar to the days away, restricted or transferred metric utilized by the Occupational Safety and Health Administration. The annual lost time incident rate is calculated by multiplying the number of lost time cases by 200,000 hours and dividing the result by the total number of hours worked by all employees during the year.* 

*(5)* *The total recordable incident rate is calculated by multiplying the annual number of OSHA Recordable Cases by 200,000 and dividing the product by the total hours worked by all employees during the year. The number 200,000 is used in the calculation to represent the number of hours worked in a year by 100 employees working 40 hours per week over 50 weeks, which provides the basis for calculating the incident rate for the entire year.*

## **Proposal 1** **Election of Directors** 
Our Board is divided into three classes, with one class elected at each annual meeting of shareholders. Directors of each class are elected to serve for three-year terms. Pursuant to the Company's Amended and Restated Bylaws (the "Bylaws") the Board is authorized, by resolution from time to time, to fix the size of the Board provided that the Board consists of not less than six nor more than ten directors. Accordingly, the Board has by resolution fixed the size of the Board at eight directors effective until immediately prior to the election of directors at the Annual Meeting, at which time the Board has fixed the size of the Board at seven directors.

Two directors (out of a total of seven) are to be elected at the Annual Meeting to serve for a three-year term ending at the Annual Meeting of Shareholders in 2029 and the election and qualification of their respective successors. Pursuant to the Board's continued refreshment program, Mr. Richard A. Baldridge will be retiring from the Board upon the election of directors at the Annual Meeting. The Board is most grateful to, and thanks Mr. Baldridge for his 13 years of service.

If elected at the Annual Meeting, Mr. Oswald and Ms. Strycker will serve for a three-year term ending at the Annual Meeting of Shareholders in 2029 and until their respective successors have been duly elected and qualified, subject to their earlier death, resignation, or removal.

In the absence of a contrary direction, proxies will be voted for the election of Mr. Oswald and Ms. Strycker. If any nominee becomes unable or unwilling to serve as a director at the time of the Annual Meeting, the individuals named as proxies may vote for a substitute nominee chosen by the present Board to fill the vacancy. Alternatively, the Board may reduce its size. We have no reason to believe that Mr. Oswald and Ms. Strycker will be unwilling or unable to serve for the stated term if elected as directors. In the event that anyone other than Ducommun's two nominees is nominated for election as a director, the individuals named on the proxy card (the "Proxy Holders") are not required to vote for all of the nominees and in their discretion may cumulate votes.

## **Corporate Governance** 

### **Directors' Skills and Diversity** 
The Board of Directors believes that its members should possess a combination of skills, professional experience, and diversity of backgrounds necessary to oversee our management and support the interests of our shareholders. In addition, the Board has outlined in our Corporate Governance Guidelines certain attributes it believes every director should possess. Accordingly, the Board and its Corporate Governance and Nominating Committee consider the qualifications of directors and director candidates both individually and in the broader context of the Board's overall composition and our current and future needs.

The Corporate Governance and Nominating Committee is responsible for developing and recommending director membership criteria to the Board for approval. The current criteria include experience and expertise, sound judgment, a record of accomplishment in areas relevant to our business activities, unquestionable integrity, a commitment to representing the interests of the Company's shareholders in fulfillment of our goals and objectives, the willingness to devote sufficient time, energy and attention to Board activities, and the absence of potential conflicts with our interests. In addition, the Corporate Governance and Nominating Committee periodically evaluates the composition of the Board to assess the skills, experience and perspectives that are currently represented, to determine which of those attributes will be valuable in the future given our current state and strategic direction under our VISION 2027 game plan for investors, and to evaluate the effectiveness of the overall Board dynamic.

While we do not have a formal policy on Board diversity, Ducommun's Corporate Governance Guidelines reflect the Board's belief that a blend of different professional experiences and personal perspectives contributes to the quality of the Board's oversight and are essential enablers of effective governance. With that, we are committed to the belief that Board diversity is not reflected solely in the variety of our directors' professional backgrounds and experiences, but rather that the quality of our deliberations and decisions, and of our overall governance, is enhanced by the perspectives represented by directors with cognitive diversity and a wide range of personal characteristics, particularly, gender, race, cultural heritage and age. As a result, the Corporate Governance and Nominating Committee has been deliberate in striving to achieve a broad range of diversity in the pools from which qualified director candidates are selected, as it has worked over the past few years to identify successors to a group of very capable directors. Over that time and with the assistance of Spencer Stuart, an independent executive search firm, the Corporate Governance and Nominating Committee successfully identified and engaged Mmes. Drazba, Kramer and Strycker, and more recently, Messrs. Carter, Korte and Boehle, each from competitive pools of candidates, and recommended to the Board that they each be appointed as directors. These appointments are part of Ducommun's robust director refreshment program designed to help ensure that the Company's Board has the best mix of skills, cognitive diversity and a variety of experiences necessary to support Ducommun's leadership team in driving our VISION 2027 Strategy and enhance shareholder value.

The Corporate Governance and Nominating Committee supports the Board's commitment to engaging a diverse field of director candidates. The Corporate Governance and Nominating Committee is confident that this commitment will contribute to better representation and higher visibility for individuals with diverse perspectives and personal characteristics.

### **Director Independence** 
Our Corporate Governance Guidelines provide that a majority, and preferably at least two-thirds, of the Board must be independent. Accordingly, the Board has determined that each of Mmes. Drazba, Kramer and Strycker, as well as Messrs. Baldridge, Boehle, Carter, and Korte qualify as independent directors as defined in the New York Stock Exchange's ("NYSE") listing standards.

### **Board Leadership Structure** 
&nbsp;&nbsp;&nbsp;&nbsp;• **Stephen G. Oswald serves as the Chairman, President and Chief Executive Officer** 

• **Shirley G. Drazba serves as the Lead Independent Director** 

• **7 of our 8 current directors are independent under the NYSE listing standards** 

• **All of the members of the Board's Audit, Compensation and Corporate Governance & Nominating Committees are independent** 

Our Bylaws provide the Board with the discretion to elect a Chairman who may or may not be one of our officers, and this flexibility enables the Board to decide what leadership structure is in shareholders' best interests at any given time. Moreover, the Board periodically reviews its structure and leadership as part of its succession planning process. As a result of such reviews, Mr. Oswald has served as Chairman since our 2018 annual meeting.

Specifically, the independent members of the Board have determined that, at this time, having the same person serve as Chairman and CEO provides us with the most effective leadership structure because:

&nbsp;&nbsp;&nbsp;&nbsp;• A combined Chairman-CEO structure provides
 the Company with a senior leader who serves as the primary liaison between our Board and management, as well as the primary public
 face of Ducommun, which demonstrates clear accountability to shareholders, customers and other stakeholders, and which has been very
 effective and efficient in executing management's VISION 2027 Strategy and creating value for shareholders.

• Our CEO has extensive knowledge of all aspects of our business,
 operations and risk, which facilitates more effective discussions with the Board via his capacity as Chairman.

• A combined Chairman-CEO role is a valuable resource to
 independent directors during and in between Board meetings.

In the future, the roles of Chairman and CEO may be filled by the same or different individuals.

The Board also believes that strong, independent leadership and oversight of management is an important component of effective governance. To that end, on February 25, 2025, the Board appointed Shirley G. Drazba as the Lead Independent Director. The Lead Independent Director has significant leadership authority and responsibilities, including those as set forth below.

### **The Board's Role in Risk Oversight** 
The Board oversees risk management both collectively and through its individual committees, and regularly reviews information regarding, and risks associated with, our operations, liquidity, artificial intelligence and cybersecurity, as well as our CER program and is highly engaged with management in identifying and overseeing such matters.

As part of the Board's role in overseeing the Company's enterprise risk management ("ERM") program, it devotes time and attention to artificial intelligence, cybersecurity and data privacy related risks in conjunction with the Innovation Committee. The Board and the Innovation Committee receive reports on artificial intelligence, cybersecurity, data privacy and technology-related risk exposures from management, including our head of Information Technology ("IT") and security, at least once a year and more frequently as applicable.

We have an enterprise-wide approach to addressing cybersecurity risk, including input and participation from management and support from our IT Steering Committee that is composed of our Senior Vice President Electronics and Structural Systems, Chief Financial Officer, General Counsel, Chief Human Resources Officer, Vice President Supply Chain Management and Head of IT and Cybersecurity. Our cybersecurity risk management program leverages the National Institute of Standards and Technology Framework which is augmented with Cybersecurity Maturity Model Certification components to meet our particular needs. We regularly assess the threat landscape and take a holistic view of cybersecurity risks, with a layered cybersecurity strategy based on protection, detection and mitigation. Our IT security team, which is composed of internal resources, reviews enterprise risk management-level cybersecurity risks at least annually.

While the full Board has the ultimate oversight responsibility for the risk management process, various Board committees also have risk management oversight responsibilities over certain substantive areas. The Board believes that its programs for overseeing risk, as described below, would be effective under a variety of leadership frameworks. Accordingly, the Board's risk oversight function and committee responsibilities support the current leadership structure. The key risk oversight responsibilities of each of the Board's committees are depicted in the diagram below:

**The Board**

The Board plays a direct role in our ERM program, including but not limited to artificial intelligence, cybersecurity and sustainability, and receives regular reports from the chairs of the respective committees with respect to the risks overseen by each.

### **Nominating Process** 
The Corporate Governance and Nominating Committee believes that all nominees for election as a director of Ducommun must, at a minimum, have:

&nbsp;&nbsp;&nbsp;&nbsp;• relevant experience and expertise;

• sound judgment;

• a record of accomplishment in areas relevant to our business activities;

• unquestionable integrity;

• a commitment to representing the interests of our shareholders in the fulfillment of our goals and objectives;

• independence, and the absence of potential conflicts with Ducommun's interests;

• the willingness to devote sufficient time, energy and attention in carrying out the duties and responsibilities of a director; and

• the willingness to serve on the Board for an extended period of time.

In identifying candidates to serve on the Board, the Corporate Governance and Nominating Committee follows the process delineated in the diagram below.

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Identify Current Board Composition** | ![](ldco2026_def14ax24x1.jpg) | **Conduct Self-Assessment** | ![](ldco2026_def14ax24x1.jpg) | &nbsp;&nbsp;**Identify Skills Needed in the Future** |
| **Identify Current Board Composition** | ![](ldco2026_def14ax24x1.jpg) | The Board conducts periodic evaluations of its leadership structure, committee composition, structure and scope, most recently in 2023, to identify evolving areas of need that the directors believe are important to our overall governance and for the execution of our VISION 2027 Strategy. | ![](ldco2026_def14ax24x1.jpg) | &nbsp;&nbsp;**Identify Skills Needed in the Future** |
| The evolving needs of the Board are identified and evaluated based on a survey developed by our Corporate Governance and Nominating Committee, taking into account factors such as the Board's current composition, the range of talents, experiences and skills that would best complement those already represented on the Board, the balance of management and independent directors, the diversity in perspectives represented by directors of different personal characteristics, and the need for financial or other specialized expertise. | ![](ldco2026_def14ax24x1.jpg) | The Board conducts periodic evaluations of its leadership structure, committee composition, structure and scope, most recently in 2023, to identify evolving areas of need that the directors believe are important to our overall governance and for the execution of our VISION 2027 Strategy. | ![](ldco2026_def14ax24x1.jpg) | The Board uses the results of the assessments to determine whether its current mix of experience, skills and perspectives are addressing identified areas of need and reveal capabilities that will be required to address those areas in the near future. |

---

As a result of the regular and on-going assessments described above, the Corporate Governance and Nominating Committee determined that the Board would benefit from additional expertise in the areas of product strategy, human capital management and finance, and retained Spencer Stuart, an independent search firm, to conduct searches for the best qualified candidates in these fields utilizing a disciplined process that included research and reviewing the firm's global database and network of contacts. As a result, Spencer Stuart's searches identified Ms. Drazba in 2018 and Ms. Kramer and Ms. Strycker in 2021, all from competitive pools of candidates.

More recently, the Corporate Governance and Nominating Committee determined that the Board would benefit from additional skill sets in the areas of engineering, product development and additional functional expertise, which resulted in Mr. Carter being identified from a competitive pool of candidates and his subsequent election to the Board in February 2024. Thereafter, a self-assessment completed by the Board identified the need for additional operational leadership and financial expertise. Accordingly, the committee once again retained Spencer Stuart to conduct a search for the best qualified candidates in those fields and as a result of its process, identified Messrs. Korte and Boehle from a competitive pool of candidates. The addition of five new directors since 2021 demonstrates the robustness of the Company's refreshment program and the benefit to shareholders of having new perspectives and skill sets become part of Board deliberations. A summary of our Board's refreshment activities is provided in the diagram below:

---

All director candidates considered for nomination by the Corporate Governance and Nominating Committee must complete a questionnaire, provide such additional information as the committee may request and meet with our incumbent directors.

The Corporate Governance and Nominating Committee will consider director candidates recommended by shareholders in accordance with the procedures set forth in Article II Section 13 of our Bylaws. Shareholders may submit the name of individuals for consideration as a director candidate not later than the close of business on the ninetieth (90<sup>th</sup>) day nor earlier than the close of business on the one hundred twentieth (120<sup>th</sup>) day prior to the first anniversary of the preceding year's annual meeting. The Corporate Governance and Nominating Committee considers and evaluates candidates recommended by shareholders in the same manner that it considers and evaluates other director candidates.

### **The Board's Role in Management Succession Planning and Talent Development** 
One of the primary responsibilities of our Board is identifying and developing talent for the executive leadership roles at Ducommun, particularly those of the CEO and other named executive officers ("NEOs"). The Board has assigned to our Compensation and Corporate Governance & Nominating Committees, as set forth in their respective charters, the shared responsibility of overseeing the Company's talent management and succession planning process, with the Compensation Committee taking the lead role and providing updates to the full Board.

The Compensation Committee of the Board has engaged in an annual succession planning process with the CEO and V.P., Chief Human Resources Officer through which certain high performing and other key individuals are identified throughout the organization as potential successors to our CEO and other NEOs, and to ensure our ability to execute, realize and maintain the objectives articulated in our VISION 2027 Strategy and beyond. For each identified high potential employee, a development plan is cultivated over a 1-2-, 3-5 and 5 plus year timeline, which includes on-going training, development and coaching, stretch assignments, exposure to high-profile projects, and in some cases, interaction with the Board so directors may gain familiarity with the individual.

As part of the Company's talent and succession planning, the Compensation Committee relies on defined attributes for the qualities the Board seeks in the CEO and other NEO roles. The Compensation Committee and Board periodically assess, and update when appropriate, those attributes that are most relevant to our succession planning process. The key elements of our succession planning process are depicted in the diagram below:

### **Annual Board and Committee Evaluations** 
Our Board and each of its committees evaluate their effectiveness and performance by completing an annual self-evaluation process, which is coordinated by the Corporate Governance and Nominating Committee together with our Lead Independent Director. These evaluations are conducted through a combination of formal and informal processes, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;• The Board, along with each of its committees, annually conducts a self-evaluation of its performance which includes considerations as to: the composition of the Board and its committees; whether committee charters remain appropriate; meeting content and whether the amount of time dedicated to agenda items are appropriate; directors' concerns about the Board's performance and that of its individual committees; and suggestions for addressing such issues. The foregoing process is depicted in the diagram below:

![](ldco2026_def14ax30x1.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;• At the end of each regular Board meeting, the Board holds executive sessions outside the presence of management at which feedback is provided to the Lead Independent Director.

• The Corporate Governance and Nominating Committee, in conjunction with the Lead Independent Director, periodically reviews the composition of the entire Board to assess the skills, experience and perspectives that are currently represented on the Board, and to determine what skills and experience would be valuable in the future given our current state and strategic plans.

Feedback from these processes is communicated to the Chair of the Board, the Chair of the Corporate Governance and Nominating Committee, and the Lead Independent Director so that appropriate follow-up measures can be discussed, implemented and monitored. As discussed in the "Nominating Process" section above, as a result of recent self-evaluations, the Board determined that it would benefit from additional proficiency in the areas of engineering, product development and functional expertise, as well as operational leadership experience and additional financial acumen. Our newest directors, Messrs. Carter, Korte and Boehle have each enhanced the Board with these and other areas of expertise since their appointments.

### **Director Orientation and Continuing Education** 
Ducommun provides an orientation program for all new directors, not only with respect to their roles on the Board but also as members of the committees on which they will serve. In addition, Ducommun provides ongoing education and development for its directors to help them continuously improve their contributions as individual directors and collectively as a Board and pays for all reasonable expenses for any director who wishes to attend external continuing education programs.

We expect to engage regularly in meaningful conversations with shareholders concerning our business, executive compensation, corporate, environmental and social responsibility, and other governance topics.

To this end, in 2025, we continued to engage with our shareholders. Specifically, we met with certain of our significant shareholders to discuss, among other matters, the Company's progress under its VISION 2027 Strategy. Our Board believes that such candid and specific feedback from its shareholders will enhance our governance, corporate responsibility and compensation practices, and will contribute positively to Ducommun's mission, performance and return to shareholders. A summary of our engagement efforts, along with actions taken in response to shareholder feedback are summarized in the tables below:

Mr. Ducommun served on our Board since 1985 and was the only director who participated in the Directors' Deferred Income and Retirement Plan. Under this plan, which has been closed to new participants since 1997, Mr. Ducommun had the ability to elect to defer payment of all or part of his fees for service as a director until his retirement from service on the Board, which retirement was effective April 30, 2025. Deferred directors' fees could be notionally invested, at the election of Mr. Ducommun, in a fixed interest account or a phantom stock account that tracked the value of our common stock, including dividends, if any.

#### **2025 Director Compensation Table** 
The following table presents the compensation earned by, or paid to, the non-employee directors for the year ended December 31, 2025 for their services to Ducommun.

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *On May 8, 2025, 2,300 restricted stock units were granted to each of Mmes. Drazba, Kramer and Strycker, and Messrs. Baldridge, Boehle, Carter, and Korte. Other than as set forth in this footnote (1), our non-employee directors did not hold any other outstanding equity awards as of December 31, 2025.* 

*(2)* *These amounts represent the aggregate grant date fair value of stock awards granted in 2025 as calculated pursuant to Financial Accounting Standards Board's Accounting Standards Codification Topic 718, disregarding the estimate of forfeitures. The methodology and assumptions used in the valuation of stock awards are contained in Footnote 11 to our consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2025.* 

*(3)* *The non-employee directors received awards of restricted stock units for a number of shares (rounded to the nearest 100 shares) equal to the stated dollar amount divided by the average closing price of our common stock on the NYSE on the five trading days immediately preceding the date of grant, which was $60.04. All of the restricted stock unit awards granted to our non-employee directors vest on the one-year anniversary of the respective date of grant.* 

*(4)* *As discussed above, Mr. Ducommun is the only director who participated in the Directors' Deferred Income and Retirement Plan. Accordingly, the amount for Mr. Ducommun listed in the table able represents his annual retainer fee of $25,000 for the shorter of his life or a period of twelve years, which Mr. Ducommun became entitled to on his retirement from the Board in April 2025.* 

*(5)* *Messrs. Ducommun and Flatt retired from the Board as of April 30, 2025 and as such, were not awarded any restricted stock units in 2025.* 

#### **Director Stock Ownership Policy** 
In August 2020, the Compensation and Corporate Governance and Nominating Committees of the Board updated the stock ownership requirements covering all non-employee directors and executive officers. Under the revised policy, non-employee directors must acquire and hold shares of our common stock equal in value to at least five times the annual Board cash retainer of $80,000. Non-employee directors are expected to meet these holding requirements by December 31<sup>st</sup> of the fifth year following their initial election to the Board. For purposes of determining compliance with the policy, a non-employee director's stock ownership is calculated by multiplying the aggregate number of shares owned and unvested restricted stock units by the average trading price of our stock over a twelve-month period ending on December 31<sup>st</sup> of each calendar year, divided by the annual Board cash retainer. All directors are in compliance or have additional time in which to comply with the stock ownership guidelines as of December 31, 2025.

### **Corporate and Environmental Responsibility** 
We are committed to improving the lives of our shareholders, employees, customers, business partners, and the communities in which we operate. To that end, we believe having a strong focus on corporate responsibility, including environmental matters, and conducting our business in an ethical, transparent and accountable manner, creates value for all of our stakeholders.

We provide an overview of our corporate environmental and responsibility initiatives and practices below. Our Corporate and Environmental Responsibility and Task Force on Climate-Related Financial Disclosures Reports are available via the "Environment & Sustainability" link on our Investor Relations webpage.

#### **Board-Level Oversight of Corporate and Environmental and Responsibility Program** 
Our CER initiatives are overseen by the Board in general, and specifically, the Corporate Governance and Nominating Committee. In particular, the Corporate Governance and Nominating Committee reviews and provides oversight over CER initiatives we have implemented, and which are of potential interest to our stakeholders. In 2020 and based on management's recommendations, the Corporate Governance and Nominating Committee approved the development of a CER program substantially based on the Sustainability Accounting Standards Board's Aerospace and Defense Industry Standard (the "SASB Standard"), as modified, as being the standard most reflective of, and relevant to, Ducommun's operations. Subsequently, in 2021, we formally established a CER steering committee composed of senior executives to monitor and manage the initiatives approved by the Corporate Governance and Nominating Committee to further strengthen our CER program. More recently, we incorporated the use of the Global Reporting Initiative ("GRI") framework into our SASB Standard-based CER program and further advanced our climate-related disclosures by publishing a stand-alone Task Force for Climate Financial Disclosure ("TCFD") report, which is available on our website. The Corporate Governance and Nominating Committee and the full Board receive regular updates on the status of these initiatives.

#### **Operating Responsibly** 
We understand the importance of building trust with our investors, customers, vendors and suppliers, and that the foundation for doing so begins with our employees. To establish this trust and commitment, we rely on an anonymous hotline to support our Code of Business Conduct and Ethics and empower our employees to provide suggestions and report concerns or instances of misconduct. In keeping with our foundational core values of honesty and trust, we offer employees regular training and monthly ethics bulletins to promote a culture of high ethical standards where employees feel free to voice concerns.

We are also committed to respecting human rights and establishing expectations for high levels of ethical conduct throughout our supply chain. Ducommun's California Transparency in Supply Chains Act Disclosure Statement and Prohibition Against Trafficking in Persons Policy are both available in the Corporate Governance section of our Investor Relations webpage.

Employee safety is also one of our top priorities and annual areas of focus as evidenced by a Lost Time Incident Rate of zero over the past year, which is a remarkable 100% improvement over our baseline year of 2019. Additionally, we offer an annual health fair, flu shot clinics, and onsite grief counseling support services to our employees as part of our health and wellness initiatives.

In 2025, we continued to enhance our employee assistance plan services and benefits by providing our workforce with access to Talkspace Go, a mobile app that provides self-guided counseling support and features live group classes hosted by professional counselors. Importantly, our employees have access to a variety of resources such as counseling support, training and development on managing remote work, stress management and emotional intelligence, and improved self-help resources including tools, videos, financial calculators and informative articles to assist with life decisions and events such as adoption, relationship troubles, legal issues, financial well-being, and health issues.

#### **Workplace Health and Safety** 
In 2021, Ducommun adopted environmental health and safety ("EHS") key performance indicators ("KPIs") that were regularly communicated across the enterprise by senior management in order to improve safety outcomes. In 2025, we continued to invest in infrastructure to improve internal safety practices related to key processes. In addition, we completed the implementation of EHS software tools for performance centers to track and further reduce, lost time and total recordable incident rates.

Over the past four years, Ducommun's lost time incident rate ("LTIR")\* dropped to zero, a remarkable 100% decrease over the period, and our total recordable incident rate ("TRIR")\*\* decreased by approximately 72% during that same time frame, both reflective of world-class performance.

The Board of Directors is kept apprised with regular updates as to the successful implementation of our safety protocols during the year.

*\** *Lost time incidents are defined as incidents that resulted in days away from work. This measure is similar to the days away, restricted or transferred metric utilized by the Occupational Safety and Health Administration. The annual lost time incident rate is calculated by multiplying the number of lost time cases by 200,000 hours and dividing the result by the total number of hours worked by all employees during the year.*

*\*\** *The total recordable incident rate is calculated by multiplying the annual number of OSHA Recordable Cases by 200,000, and dividing the product by the total hours worked by all employees during the year. The number 200,000 is used in the calculation to represent the number of hours worked in a year by 100 employees working 40 hours per week over 50 weeks, which provides the basis for calculating the incident rate for the entire year.*

#### **Environmental Initiative Highlights** 
In support of our pledge to deliver exceptional value to all stakeholders, we are committed to the following with respect to our environmental management practices:

&nbsp;&nbsp;&nbsp;&nbsp;1. Striving to avoid adverse impact and harm to the environment in the communities in which we do business, and to identify business partners who share these values.

2. Promoting the creation of a culture of compliance with all applicable laws and regulations pertaining to the environment and natural resources.

3. Endeavoring to improve our Environmental Management System and work to assure that employee awareness and performance are priorities of our operating system.

4. Establishing meaningful objectives in the pursuit of environmental, health and safety excellence.

Below is a summary of our performance over the four-year time period between 2022 and 2025 relating to our greenhouse gas emissions. Over the past four years Ducommun has decreased its Scope 1 greenhouse gas emissions by 17% through a combination of energy efficiency upgrades, boiler conversions and process optimization initiatives. The Company also achieved a 55% reduction in its Scope 2 greenhouse gas emissions over the same time frame by procuring energy from renewable sources, converting to LED lighting and implementing HVAC upgrades. Moreover, the Company has reduced its Scope 3 emissions by 20% since 2023 by lowering the volume of waste generated and transported for off-site disposal. Ducommun now obtains 39% of its energy needs from renewable sources:

#### **Identifying and Mitigating Climate-Related Risks** 
Ducommun understands that climate change and global warming are not far-off concerns but present immediate challenges that could pose potential operational, regulatory and reputational risks to companies. For this reason, Ducommun has recognized the increasing urgency of climate-related threats and the need to proactively manage potential impacts to our business strategy, operations and supply chain. In 2025, we released our first-ever climate risk report aligned with the TCFD framework, which calls for clear, consistent and transparent disclosures related to climate-related financial risks. Accordingly, our TCFD report is structured around four key pillars:

&nbsp;&nbsp;&nbsp;&nbsp;1. *Governance:* Outlines how climate-related issues are overseen by the Board and top executives;

2. *Strategy:* Assesses how climate-related risks and opportunities could affect our operations in the short, medium and long-term;

3. *Risk Management:* Outlines how climate risks are identified, assessed and integrated into our broader risk management framework; and

4. *Metrics and Targets:* Details the data and benchmarks used to measure and track climate-related performance.

Through this framework, we identified both physical-(e.g. extreme weather events) and transition-related risks (e.g., regulatory changes, carbon pricing, policy, market and reputational risks), while also uncovering opportunities for sustainable innovation and the utilization of low-carbon materials.

For a full overview of our process for identifying and mitigating climate-related risks, please visit the following link on our website at: https://investors.ducommun.com/static-files/b681e276-c668-47bc-b7b5-29ba40e044f4.

#### **Investment in Our Employees and the Future Generation** 
We have implemented and maintain several programs for the financial and educational well-being of our employees and their families. For example, in 2019, we introduced an Employee Stock Purchase Plan, which provides employees the opportunity to share in Ducommun's success and continued growth by purchasing the Company's stock. The plan allows eligible employees to accumulate contributions through after-tax payroll deductions to purchase shares of Ducommun stock at a 15% discount. In 2025, we continued to grow the program, with overall participation levels increasing by 25% since the program's inception. In addition, our 401(k) program has a 93% participation rate among eligible employees, with annual training and monthly educational sessions held at each Ducommun performance center. Both programs emphasize the importance of investing and building for the future for our employees and their families.

The Ducommun Scholarship Program is an exclusive benefit for the children and grandchildren of full-time Ducommun employees who plan to continue their education by attending a four-year college or university, or a two-year accredited technical or vocational program. Student applicants are evaluated by an independent scholarship firm that administers the application and review process, and scholarships are awarded based on factors such as academic performance, demonstrated leadership, participation in school and community activities, honors, work experience, goals and aspirations. In 2025, Ducommun awarded a record 94 academic and vocational scholarships, which included 40 new awards and the renewal of 54 previously awarded scholarships, an increase from the 92 scholarships awarded in 2024. Students can renew their scholarship awards for each academic year, allowing them to work toward a two- or four-year degree, provided they continue to meet minimum academic performance levels and have a parent or grandparent that is employed by Ducommun. The total value of the scholarship awards in 2025 was $259,000 and over $1.4 million in scholarships have been awarded since the program's inception.

Ducommun also offers a tuition assistance program to encourage employees to continue their formal education. The program provides financial assistance to eligible employees for completing courses that align directly with an employee's assigned job function or that will help prepare them for future advancement within the Company. In 2025, Ducommun issued tuition reimbursement payments totaling almost $30,000 to employees in various functional departments, including engineering, accounting, quality, sales, supply chain and logistics.

#### **Talent Development** 
Employee engagement is an ongoing initiative at Ducommun with a focus on driving the continued individual recognition of employees and teams and improving the work environment to provide individuals with the tools and resources to do their jobs well and creating a safe and secure work environment where a culture of core values and leadership can exist. Through engagement surveys, we take a pulse of the organization and will continue to focus on areas that are of most importance to our employees.

We also believe that the talent and skills of our employees allow us to drive innovation across the organization in support of our customers and their needs. To that end, and as part of our ongoing focus on organizational development, Ducommun continues to enhance various tools and resources available to our employees. In 2024, we began a partnership with Franklin Covey, an independent consulting firm, to support our talent development initiatives. As a result, in 2025 we launched a formal leadership development training program for key individuals across the organization with the goal of developing a "leader's mindset" by equipping them with essential skills that enhance employee engagement, improve collaboration and communication, and drive results. Over 100 leaders from across Ducommun participated in one of more than thirteen different leadership workshops offered across the nation during the year. Additionally, in 2025 the Company partnered with Dale Carnegie to provide executive coaching and development for its senior leaders.

Moreover, within our human capital and performance management systems, talent and 360° performance reviews are vital to increasing our capabilities, productivity and efficiency in every facet of the organization. Specifically, robust performance management processes support our philosophy of ongoing coaching and feedback as well as fostering employee engagement and collaboration within all levels of the organization, and these processes serve as part of our focused effort to drive organizational effectiveness, process efficiency and talent development. In 2025, we developed an online formal talent review and succession planning process, which will formally launch in 2026 and will facilitate our ability to proactively and intentionally identify and develop internal talent in a manner that aligns competencies with our core values, annual key focus areas, and employee and leadership expectations.

####  ***Newsweek* Magazine's Most Responsible Companies for 2026**

#### **Community Investment** 
Ducommun is committed to being an active member of the communities in which we operate by contributing not only financial resources but also volunteering time to help these localities become stronger and better environments in which to live and work.

In September 2025, Ducommun was honored to serve as an Event Sponsor of the Orange County United Way's Rally for Change event, at which it was awarded the Employee Giving Climber Award for medium sized companies, and our corporate employees celebrated Thanksgiving by assembling math literacy kits to support local students at The United Way's Orange County, CA headquarters.

The Ducommun Foundation, founded in 2019, is a Section 501(c)(3) organization that serves as the Company's philanthropic arm dedicated to financially supporting local and national non-profit and charitable organizations in the communities in which we operate. Since its inception, the Ducommun Foundation has donated over $2.1 million to assist organizations that support veterans, active service members and military families, and efforts to end homelessness in local communities. In 2025 donations were provided to organizations such as American Red Cross, United Way, Los Angeles Fire Department, Children of Fallen Patriots and Wounded Warriors Family Support. Additionally, in honor of Veteran's Day, donations were provided to the American Battle Monuments Foundation, which maintains American military cemeteries and monuments overseas in support of those who have made the ultimate sacrifice in defending our freedom. In past years, contributions were also made to the Hire Heros USA, American Legion, Fisher House Foundation, U.S. Veterans Initiative, World Central Kitchen, UNICEF USA and other humanitarian causes.

The tables below show the beneficial ownership of more than 5% of our common stock by each of our directors and nominees for director, each executive officer named in the Summary Compensation Table contained in this Proxy Statement, and all directors and executive officers as a group. This information is as of March 2, 2026 except as otherwise indicated in the notes to the tables and does not account for any tax withholding of shares that may occur after March 2, 2026 in connection with the vesting of restricted stock units or settlement of performance stock units.

## **Proposal 2 Resolution to Approve Executive Compensation on an Advisory Basis** 
We are asking shareholders to approve on an advisory basis Ducommun's named executive officer compensation as reported in this Proxy Statement. As described below in the Compensation Discussion and Analysis ("CD&A") section of this Proxy Statement, the Compensation Committee has structured our executive compensation program to achieve the following key objectives:

1) Create a pay-for-performance compensation approach to align executive interests with those of shareholders;

2) Provide competitive levels of compensation that align pay to the achievement of our financial goals;

3) Assist in attracting and retaining qualified executives; and

4) Recognize individual and team initiatives and performance.

Ducommun's pay-for-performance compensation approach consists of a mix of shorter-term and longer-term incentive compensation, including performance stock unit awards that cliff vest at the end of a three-year performance period with a relative total shareholder return modifier, time-based restricted stock units that incrementally vest over three years and, for our CEO, revenue performance stock units with a three-year performance period. In 2025, the Compensation Committee continued to adhere to our pay-for-performance compensation philosophy and used its discretion to make only minor adjustments for one-time costs consistent with past practices.

#### **Executive Summary and 2025 Performance Highlights** 
Ducommun had strong performance across all areas in 2025 despite the lower revenues in commercial aerospace mainly due to destocking. With respect to annual incentives, the Compensation Committee took the following factors into account:

&nbsp;&nbsp;&nbsp;&nbsp;a) On a year-over-year basis, Ducommun's market capitalization increased by 51%, resulting in shareholders
 realizing almost $500 million in value in 2025 and demonstrating the effectiveness of the Company's pay-for-performance
 compensation philosophy in aligning executives' interests with those of shareholders;

b) The Company's stock price increased by 49% on a year-over-year basis, rising from $63.66 to $95.13 per share as
 measured on December 31, 2024 and December 31, 2025, respectively, providing substantial value to shareholders;

c) Ducommun has seen year-over-year growth in total shareholder return since 2021, with a 40% higher cumulative total shareholder
 return in 2025 compared to the Russell 2000 index and a three-year relative total shareholder return at the 78<sup>th</sup>percentile,
 in each case, due to management's demonstrated track-record of strong operational leadership and effective cost management;

d) For the third consecutive year, the Company established a new all-time revenue record of approximately $824.7 million
 with healthy year-over-year top line growth of almost 5% and surpassing the prior record of $786.6 million in 2024,
 as Ducommun continued to benefit from offloading with the right product portfolio, strong operating discipline and by leveraging
 its lean, highly focused performance center concept, with net revenue per employee increasing by approximately 7% over the
 prior year all while overcoming challenges relating to workforce availability, inflationary pressures and continued headwinds
 in the commercial aerospace market;

e) Management oversaw a very significant 180 bps increase in gross profit margins year-over-year, which is another great
 example of our operating process, Company culture, dedicated employees and strong leadership;

f) In the third full year after announcing our VISION 2027 Strategy in December 2022, revenue from Ducommun's engineered
 products business accounted for 23% of its total revenues with Adjusted EBITDA margins at 16%, both of which are either running
 ahead of, or on track with the Company's VISION 2027 goals, and demonstrating management's solid progress towards
 the financial goals and key tenets of our value creation plan for shareholders;

g) Management successfully grew the Company's defense business by 14% in 2025, driven by very strong performance in
 its missile franchise, which increased by 20% year-over-year, as well as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Increasing revenues from Ducommun's military fixed-wing aircraft business by 12% year-over-year;

(ii) Growing the Company's rotary-wing aircraft business by 18% compared to the prior year;

(iii) Overseeing the successful transition of Ducommun's Apache tail rotor business from its now-closed Monrovia, California
 facility to its Coxsackie, New York performance center, which was fully approved by Boeing for production;

(iv) Ensuring the TOW missile was ready for full production at the Company's Guaymas, Mexico performance center; and

(v) Complementing the Company's missile portfolio with a very strong radar franchise, which grew by 32% over the prior
 year and which includes marquee programs such as the SPY-6 radar system, TPY-2 radar used on the THAAD missile defense system,
 and the G/ATOA radar system utilized by the U.S. Marine Corps.

&nbsp;&nbsp;&nbsp;&nbsp;h) In 2025, the Company's net income decreased year-over-year mainly due to one-time litigation
 settlement and related costs, net, of $83.3 million net of taxes, and in the absence of which would have improved to
 $57.5 million on an adjusted basis. The Company also attained records levels of Adjusted EBITDA, with four consecutive quarters
 above $30.0 million, growing from approximately 14.8% of revenues in 2024 to 16.4% in 2025, solid progress towards the
 18% target in VISION 2027.

i) Management also successfully sold the Company's Berryville, Arkansas operation in the second quarter of 2025 and
 has been actively marketing its Monrovia, California facility as it continues to execute on the Company's strategy of
 consolidating its rooftop footprint in contract manufacturing. Ducommun remains on target to achieve $11-13 million in
 annual cost savings as articulated in our VISION 2027 Strategy.

j) Ducommun's remaining performance obligations grew to a new record level of $1.1 billion, increasing by 9% year-over-year.

k) Ducommun retaining its status as a U.S.-based manufacturer with U.S. employees and 95% of our revenue being produced in
 the U.S. The Company's only other non-U.S. facility is based in Guaymas, Mexico, which production constitutes less than
 5% of our total revenue. Imports and exports to and from that facility have been covered under the U.S.M.C.A. to date, exempting
 the Company from the impact of tariffs.

The Compensation Committee incorporated these considerations into the final annual cash incentive awards that recognized the significant individual and team performance that drove our results in 2025. Additionally, the Compensation Committee believes that our continued growth, with year-over-year increases in market capitalization, revenue, and gross profit margins positioning Ducommun and its shareholders well for further success going forward. Moreover, the Company's lean executive team compared to those of its proxy talent peer group delivers direct value to shareholders as evidenced by Ducommun's consistent year-over-year performance.

With respect to long-term incentives, the Compensation Committee continued its practice of granting performance and restricted stock units to executives, as the Company does not maintain a pension plan for our CEO or NEOs. The Compensation Committee believes these practices are consistent with our pay-for-performance compensation philosophy and maintains the alignment between executives' interests and those of our shareholders. As a result, in 2025:

&nbsp;&nbsp;&nbsp;&nbsp;• Approximately 88% of target direct compensation for the chief executive officer was at risk and 79%
 was performance based; and

• Approximately 70% of target direct compensation of the other named executive officers on average was at risk and 53% was
 performance based.

We urge shareholders to read the "Compensation Discussion and Analysis" that follows, which describes how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives, as well as the Summary Compensation Table and associated narratives and graphs related to the CD&A, which collectively provide detailed information on the compensation of our named executive officers. The Compensation Committee and the Board strongly believe that the policies and procedures articulated in the "Compensation Discussion and Analysis" are effective in achieving our goals and that the compensation of our executive officers reported in this Proxy Statement has supported and contributed to our success.

In accordance with Section 14A of the Exchange Act, and as a matter of good corporate governance, we are asking shareholders to approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the shareholders of Ducommun Incorporated (the "Ducommun") approve, on an advisory basis, the compensation of Ducommun's named executive officers as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the Summary Compensation Table and the related compensation tables, notes and narrative in the Proxy Statement for Ducommun's 2026 Annual Meeting of Shareholders.

This advisory resolution, commonly referred to as a "say-on-pay" resolution, is non-binding on the Board. However, the Board and the Compensation Committee will carefully review and consider the voting results when evaluating our executive compensation program. At the 2025 Annual Meeting, shareholders expressed overwhelming support for the compensation of our named executive officers, with approximately 91% of the votes cast (with abstentions being counted as a vote "against" the proposal) approving the "say-on-pay" resolution.

Following the vote to be conducted at our 2026 Annual Meeting of Shareholders, we anticipate that the next advisory vote to approve named executive officer compensation will occur at our 2027 Annual Meeting of Shareholders (the "2027 Annual Meeting").

A major lawsuit was settled in October of 2025 related to a plant fire in Guaymas, Mexico stemming from actions taken by individuals in 2015, before the current management team was in place at the Company, Mr. Oswald started with the Company in 2017. The current management team, led by Mr. Oswald, who have led a full and effective turnaround of the Company, successfully settled the litigation through mediation in 2025 for $150 million, thereby averting a costly and long jury trial which could have also led to an appeal process. The Company was sued for consequential damages in excess of $600 million, and through effective leadership and negotiation in the mediation process the shareholder impact was greatly reduced by the executive team's efforts. Based on the circumstances and strong positive outcome for the Ducommun shareholder, the Compensation Committee agreed to reward management for its outstanding efforts by adding back $107.3 million of litigation settlement and related costs, net, when calculating the 2025 annual incentive plan payouts in light of the Company's strong operating performance with a 180 bps increase in gross margins, a 16% increase in adjusted operating income and 17% increase in adjusted net income over the prior year. Moreover, between the date the settlement was publicly disclosed on October 9, 2025 and the record date, shareholders have been the beneficiaries of an approximately 35% increase in the Company's market capitalization, again demonstrating the effectiveness of the executive team's efforts in navigating through this significant one-time event.

#### **2025 Operations and Performance Highlights: Substantial Increase in Market Capitalization, All-Time High Revenues Resulting from Continued Execution of VISION 2027 Strategy** 
The year ended December 31, 2025 saw Ducommun, in its 176<sup>th</sup> continuous year in business, attain a 49% increase in stock price between December 31<sup>st</sup> of 2024 and 2025, rising from $63.66 to $95.13 per share, respectively, a 51% year-over-year increase in its market capitalization, a relative total shareholder return that was in the 78<sup>th</sup> percentile of the Russell 2000 Index, and all-time high revenue and gross margins levels. Our performance against critical metrics such as revenue, gross margins, operating income, net income, Adjusted EBITDA, and remaining performance obligations are summarized in the graphs below and provide demonstrated evidence of the effectiveness of the Company's VISION 2027 Strategy: we successfully increased the percentage of revenue from our Engineered Products business and aftermarket content, consolidated our facility footprint in contract manufacturing, continued our targeted acquisition program, executed our off-loading strategy with defense primes and high growth segments of the defense budget, drove strategic, value-added pricing, expanded content on key commercial aerospace platforms and continued to expand our margins all while overcoming challenges relating to inflationary pressures and a longer than expected domestic commercial aerospace recovery.

#### **Trajectory of CEO Compensation Compared to Shareholder Value** 
**CEO Compensation Compared to Shareholder Value: 2022 - 2025**

![](ldco2026_def14ax50x2.jpg)

Our Compensation Committee structures our CEO's compensation to align with the creation of shareholder value. Since 2022, the trajectory of our CEO's compensation has generally increased commensurately with, and in some periods has been outpaced by, realized shareholder value, as measured by the Company's market capitalization and stock price with two exceptions. In 2023, the Company's stock price and rTSR reflected dilution resulting from 2.3 million additional shares added via a follow-on offering rather than a decline in underlying Company performance. Additionally, in 2025, the increase in our CEO's compensation was dwarfed by the approximately 50% year-over-year increase in market capitalization and stock price, while rTSR decreased by just over a percentage point from a high in 2024.

![](ldco2026_def14ax51x3.jpg)

The following graphs depicting Net Income, Operating Income and diluted Earnings per Share reflect the one-time impact of the previously disclosed Guaymas litigation, the settlement of which was viewed positively by avoiding the incurrence of additional litigation defense costs and potential further exposure for the Company and its shareholders.

**Relative Total Shareholder Return vs. Proxy Talent Peer Group<sup>(2)</sup>**

![](ldco2026_def14ax56x1.jpg)

Our relative total shareholder return has historically either outperformed or remained comparable to those of our proxy talent peer group in each year in which such group was used as a benchmark for our compensation practices due to management's demonstrated track-record of strong operational leadership and effective cost management.

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Net Income as Percentage of Revenues, Adjusted Operating Income and Adjusted Diluted Earnings Per Share are non-GAAP financial measures. For a discussion of these measures and for reconciliation to the nearest comparable GAAP measures, see Appendix A to this Proxy Statement.* 

*(2)* *Please see the "Benchmarking and Proxy Talent Peer Group" section of the Compensation Discussion and Analysis section for a list of the proxy talent peer group used to determine 2025 compensation. The proxy talent peer group used to determine 2025 compensation for our PEO and other NEOs included: AAR Corp., AeroVironment, Inc., Albany International Corp., Astronics Corporation, Barnes Group Inc., Crane Company, ESCO Technologies, Inc., Hexcel Corporation, Kratos Defense & Security Solutions, Inc., Mercury Systems, Inc., RBC Bearings Incorporated, Standex International Corporation and Triumph Group, Inc.* 

The following graph and table compare the total shareholder return on $100 invested in Ducommun common stock with the total shareholder return on $100 invested in the Russell 2000 Index and companies identified in the "Benchmarking and Proxy Talent Peer Group" section of this Compensation and Disclosure Analysis, for the five-year period from 2021 through 2025, with the year ended December 31, 2020, serving as the base period. The Russell 2000 Index measures the performance of approximately 2,000 small-capitalization companies in the Russell 2000 Index, a larger index of publicly traded companies that represents almost 98% of the investable U.S. stock market. The total returns include the reinvestment of cash dividends.

#### **Pay for Performance Philosophy** 
Our philosophy in compensating our named executive officers is oriented towards a pay-for-performance approach. In 2025, as reported in the Summary Compensation Table and other graphs below, performance-based compensation (defined, for this purpose, as all compensation contingent on the achievement of performance goals), at target, represented a significant percentage of the total compensation of each of the named executive officers:

#### **Compensation Program Overview** 
The direct elements of our executive compensation program in 2025 are summarized below.

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| &nbsp;&nbsp;**At Risk** | &nbsp;&nbsp;**Type of<br> compensation** | &nbsp;&nbsp;**Compensation<br> element** | **Purpose** | **How paid** | **For more<br> information** |
|  | &nbsp;&nbsp;**Fixed** | &nbsp;&nbsp;**Base Salary** | Compensate named executive officers for their multiple roles and levels of responsibility, as well as individual performance. | Cash; paid bi-weekly. | Page 56 |
| &nbsp;&nbsp;**At Risk** | &nbsp;&nbsp;**Performance-based and variable** | &nbsp;&nbsp;**Annual Cash Incentive** | Designed to reward the achievement of annual financial goals based on our actual financial performance compared to targets for adjusted operating income, revenue, and adjusted cash flow from operations; actual financial performance compared to a minimum adjusted net income goal; and individual performance. | Cash, typically paid in the first quarter of the year following the year for which the incentive is earned. | Page 57 |
| &nbsp;&nbsp;**At Risk** | &nbsp;&nbsp;**Performance-based and variable** | &nbsp;&nbsp;**Performance Stock Units ("PSUs")** | Designed to reward the achievement of long-term growth in our adjusted diluted earnings per share over a three-year performance period with relative total shareholder return modifier. | Cliff vest at the end of the three-year performance period to the extent earned; paid in shares of common stock (to our CEO and other NEOs) in the first quarter of the year after the conclusion of the performance period. | Page 63 |
| &nbsp;&nbsp;**At Risk** | &nbsp;&nbsp;**Performance-based and variable** | &nbsp;&nbsp;**Revenue Performance Stock Units ("RPSUs" f/k/a PRSUs)** | Designed to reward our CEO for the achievement revenue growth targets in the last year of a three-year performance period. | Cliff vest at the end of the three-year performance period to the extent earned; paid in shares to our CEO in the first quarter of the year after the conclusion of the performance period. | Page 62 |
| &nbsp;&nbsp;**At Risk** | &nbsp;&nbsp;**Time-Based** | &nbsp;&nbsp;**Restricted Stock Units ("RSUs")** | Designed to reward the achievement of long-term growth in our stock price and to provide a long-term retention incentive. | Shares vest ratably in annual increments over three years. | Page 64 |

As shown above, our executive compensation program reflects strong pay for performance alignment, and once again, our financial performance was the most significant factor affecting compensation of the named executive officers in 2025.

Since 2016, the number of vice presidents at the Company has decreased by over 60%, demonstrating management's continued strong cost management and effective spending controls. As depicted below, Ducommun's SG&A expense is amongst the lowest of its proxy talent peer group companies based on those firms' most recent Form 10-K filings with the SEC.

In 2025, the total actual compensation of our CEO and other named executive officers as reported in the Summary Compensation Table increased in a manner proportional to overall Company performance. The Compensation Committee regularly evaluates the trajectory of our CEO's total compensation to ensure that increases are justified by the Company's performance, competitive positioning among peers and the Company's retention goals for executive leadership. The Compensation Committee believes the year-over-year increase in our CEO's compensation is proportional with our 51% year-over-year increase in market capitalization, our all-time high level of revenue achieved in 2025 and the 49% year-over-year increase in the Company's stock price. Further, the base salary of our CEO was generally consistent with a trajectory of the 75<sup>th</sup> percentile of our proxy talent peer group and published compensation data, which aligns with the Compensation Committee's general target of the 50<sup>th</sup> to 75<sup>th</sup> percentile when setting compensation metrics for our CEO.

Mr. Oswald has served as our CEO since 2017, during which time the Company's market capitalization has nearly quadrupled and revenue has increased from $558.2 million to $824.7 million. The aerospace and defense sector remains a highly competitive market for leadership, particularly for individuals like Mr. Oswald who have a demonstrated record of execution and shareholder value creation. As such, the Compensation Committee is mindful that Mr. Oswald's compensation must be competitive not only among the proxy talent peer group but also among the broader aerospace and defense sector. The increases in our CEO's compensation remain consistent with our pay-for-performance compensation philosophy. In keeping with that philosophy, eighty-eight percent (88%) of our CEO's total target compensation was at risk with seventy-nine percent (79%) being performance based, and which reflected our year-over-year growth in market capitalization, revenue and margins. The chart below depicts the alignment between our CEO's total actual compensation and revenue between 2022 and 2025.

#### **Last Year's Say on Pay Vote** 
At the 2025 Annual Meeting, shareholders expressed overwhelming support for the compensation of our named executive officers, with 91.1% of the votes cast (with abstentions being counted as a vote "against" the proposal) in favor of the "say-on-pay" advisory vote. Accordingly, the Compensation Committee considered the results of the 2025 advisory vote in connection with its regular evaluation of our executive compensation program but did not make any changes to it or our policies as a result of that vote.

### **How Compensation Decisions are Made** 

#### **Compensation Objectives** 
Our compensation programs are designed to provide competitive levels of compensation that link pay to the achievement of our financial goals, assist Ducommun in attracting and retaining qualified executives and recognize individual initiative and performance. We intend for overall compensation of the named executive officers to be at levels that are broadly competitive with other companies of similar size and complexity of operations.

We do not target any specific mix of cash versus non-cash compensation for our named executive officers. Instead, each element of compensation (salary, annual cash incentive, performance-based long-term equity and time-based restricted stock units) is awarded and targeted at amounts that are intended to be market-competitive, consistent with our compensation principles and reflect internal pay equity considerations. The Compensation Committee decided to continue to primarily rely on the grant of performance-based awards (in the form of performance stock units to our CEO and other NEOs) when awarding variable compensation to executives. This approach provides consistency with our philosophy of creating pay-for-performance compensation opportunities to enhance alignment between executives' interests and those of shareholders.

#### **Role of the Compensation Committee** 
Each element of compensation for our CEO is set by the Compensation Committee. In addition, each element of compensation for the other named executive officers is recommended by the CEO and reviewed and approved by the Compensation Committee. As discussed below, we generally target the 50<sup>th</sup> to 75<sup>th</sup> percentile of proxy talent peer group data and the 50<sup>th</sup> to 75<sup>th</sup> percentile of published survey compensation in assessing and establishing compensation for the named executive officers for several reasons. First, our executive officers assume multiple responsibilities that extend beyond the scope of their job titles and those traditionally performed by leaders in similar roles. Additionally, we target these levels to retain our executives in a very competitive labor market, thereby ensuring continuity among the senior leadership team to achieve our long-term strategic objectives. Moreover, our overall compensation mix leans heavily towards being at-risk and performance-based, which ensures that our executive officers' interests are aligned with those of shareholders.

#### **Compensation Consultant** 
The Compensation Committee retained Willis Towers Watson LLC ("WTW") as an independent compensation consultant, which did not provide any services to us in 2025 other than with respect to executive compensation. The Compensation Committee reviewed WTW's independence and completed an assessment of any potential conflicts of interest raised by WTW's work by considering the following six factors, as well as others it deemed relevant: (i) whether WTW provides other services to us; (ii) the annual dollar value of fees paid to WTW, as a percentage of WTW's total revenue; (iii) the policies and procedures of WTW that are designed to prevent conflicts of interest; (iv) any business or personal relationships between WTW consultants and members of the Compensation Committee; (v) whether any WTW consultants own Ducommun stock and if so, how much; and (vi) any business or personal relationships between WTW consultants or WTW with any of our executive officers. As a result of this review, the Compensation Committee concluded that WTW is independent and there are no such conflicts of interest.

#### **Benchmarking and Proxy Talent Peer Group** 
The Compensation Committee has the compensation consultant prepare a formal executive compensation assessment every year. For the 2025 fiscal year, WTW assessed our executive compensation compared to the proxy disclosures of our proxy talent peer group and to broader published survey compensation data and recommended appropriate changes to our executive compensation program (the "WTW compensation assessment"). Specifically, and as noted above, we generally target the 50<sup>th</sup> to 75<sup>th</sup> percentile of proxy talent peer group data and the 50<sup>th</sup> to 75<sup>th</sup> percentile of published survey compensation in assessing and establishing compensation for our named executive officers.

When developing the proxy talent peer group, the Compensation Committee is confronted with the challenge of identifying comparable companies that match the diverse portfolio of products offered by Ducommun, and for that reason, focuses on identifying a mix of companies from the aerospace and defense and industrial machinery sectors. The table below identifies the proxy talent peer group companies in the aerospace and defense and industrial machinery sectors of the Global Industry Classification Standard that were referenced by WTW and the Compensation Committee as market comparators in setting target direct compensation for our named executive officers in 2025. At the time of the Compensation Committee's review, 2024 revenue data was not readily available for certain members of our proxy talent peer group due to differences in fiscal year-end periods. As a result, revenue data has been omitted from the table below. The Compensation Committee nonetheless considers factors such as industry classification, focus and complexity, revenue, market capitalization, number of employees and total shareholder return when making its compensation decisions.

Moreover, the WTW compensation assessment compared our executive compensation levels to published survey compensation data for general industry and manufacturing companies with annual revenues of between $500 million and $2 billion, based on WTW's advice that such compensation survey data would provide a reasonable basis for benchmarking our executive compensation. The compensation survey data was gathered from the General Industry Executive Compensation Survey – U.S., Durable Products Manufacturing or All Industry data cuts, published by Willis Towers Watson Services, and the U.S. Mercer Benchmark Database – Total Remuneration Survey, published by William M. Mercer. Aggregate compensation data from the surveys was provided to the Compensation Committee.

When making compensation decisions regarding the CEO, SVP CFO and SVP Electronics and Structural Systems, the Compensation Committee reviews and relies upon both proxy talent peer group data and published survey compensation data. When making compensation decisions regarding the other named executive officers, the Compensation Committee primarily relies on the published survey compensation data included in the WTW compensation assessment because of the limited data available for comparable positions within our proxy talent peer group companies.

In reviewing proxy talent peer group and published survey compensation data, the Compensation Committee evaluates the relative percentile ranking of the CEO and the other executive officers with respect to salary, total cash compensation and total direct compensation. The Compensation Committee also considers each named executive officer's scope of responsibility, years of experience, demonstrated performance and marketability, and impact level within Ducommun relative to other executives in making compensation decisions.

### **2025 Named Executive Officer Compensation** 

#### **Base Salaries** 
In establishing the salaries for the named executive officers in 2025, the Compensation Committee considered the WTW compensation assessment of base salary levels, which indicated that the CEO's base salary was generally consistent with a trajectory of the 75<sup>th</sup> percentile of our proxy talent peer group and published survey compensation data. Moreover, the base salaries of the other named executive officers were generally consistent with a trajectory of the 25<sup>th</sup> to 50<sup>th</sup> percentiles of published survey compensation data. Accordingly, the Compensation Committee made the base salary changes shown below for 2025 in recognition that our executive officers assume multiple responsibilities that extend beyond the scope of those traditionally performed by leaders in similar roles, and to reward executives for their 2024 performance and our continued progress towards achieving the long-term goals articulated in our VISION 2027 Strategy. The base salary increases for these individuals in fiscal year 2025 reflect the extensive responsibilities these NEOs assumed.

#### **Annual Cash Incentives** 
Annual cash incentives are awarded based on our actual financial performance compared to targets for three performance metrics: operating income; net revenues; and cash flow from operations, as long as Ducommun exceeds an adjusted net income threshold of $10 million. The performance metrics and their weightings are depicted in the diagrams below.

The Compensation Committee chose these performance measures because it believes that growth along those metrics is essential to our objective of providing superior long-term total shareholder return. At the beginning of each year, the Compensation Committee utilizes a bonus plan framework to establish and approve the threshold, target and maximum goals for the financial performance measures and the formula for funding the bonus pool for the given plan year. The long-standing framework utilized by the Compensation Committee in establishing the financial performance measures sets forth certain exclusions in the determination of the financial metrics, including the effects of changes in accounting principles, transaction-related costs or expenses and other one-time costs.

The 2025 goals for the financial performance measures approved by the Board contemplated that attainment of the maximum level of net revenue and operating income metrics would set all-time records for Ducommun, further aligning management's interests with those of shareholders. The maximum goal for operating income reflects an approximate 16% increase from the maximum operating income performance goal set for 2024 and an approximate 11% increase from the actual operating income performance in 2024. The maximum goal for net revenue reflects a $36.5 million increase from the actual net revenue achieved in 2024 and an approximate 1.8% or $14.3 million increase from the net revenue maximum performance goal set with respect to the 2024 awards. The maximum goal for cash flow reflects an approximate 8% or $3.3 million increase from the maximum cash flow goal set for 2024.

The Compensation Committee establishes a target annual cash incentive award for each named executive officer, expressed as a percentage of base salary. In setting the annual cash incentive target amounts, the Compensation Committee considers the WTW compensation assessment and sets appropriate targets relative to the relevant market and survey data. Annual cash incentive payouts can range from zero to a maximum of three times the targeted percentage, depending on performance. The maximum is considered appropriate in recognition of the stretch nature of the performance goals and the benefit bestowed upon shareholders should they be attained.

**Achievement of Performance Goals in 2025**

In determining actual payouts under the 2025 annual incentive plan, the Compensation Committee and Board first determined that Ducommun exceeded the adjusted net income threshold of $10 million. Net income was adjusted in accordance with the Compensation Committee's long-standing bonus plan framework, which provides for the exclusion of non-recurring expenses, such as the settlement expenses relating to the Guaymas, Mexico performance center litigation, as further detailed in the table below. The Compensation Committee then reviewed Ducommun's performance against each metric established under the annual incentive plan to determine the award's funding by metric, applied the appropriate weight to each metric and calculated the actual funding for the 2025 annual incentive plan.

![](ldco2026_def14ax63x1.jpg)

The table below depicts the threshold, target, and maximum goals for each metric under the 2025 annual incentive plan and our actual performance.

**Notably, in October 2025, the management team, led by Mr. Oswald, was able to successfully settle the litigation related to the fire at the Company's Guaymas, Mexico performance center, and which allegedly resulted from the actions of individuals in 2015, prior to the current management team being appointed to their respective offices. The senior leadership team attended several mediation sessions in an effort to settle the litigation, the successful resolution of which avoided the potential for the Company being exposed to incurring additional defense costs, further liability and negative publicity, all to the benefit of shareholders. Based on the circumstances and strong positive outcome for the Ducommun shareholder, the Compensation Committee agreed to reward management for its outstanding efforts by adding back $107.3 million of the settlement payment and litigation costs, net, when calculating the 2025 annual incentive plan payouts in light of the Company's strong operating performance with a 180 bp increase in gross margins, a 16% increase in adjusted operating income and 17% increase in adjusted net income over the prior year. Moreover, between the date the settlement was publicly disclosed on October 9, 2025 and the record date, shareholders have been the beneficiaries of an approximately 35% increase in the Company's market capitalization.**

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Includes adjustments consistent with historical practices.*

The Compensation Committee adhered to its long-standing bonus plan framework in making such adjustments to the Operating Income for determinations under the 2025 annual incentive plan.* 

**Additional Cash Bonuses**

In the first quarter of 2026, the Compensation Committee approved discretionary bonuses for each of Mr. Mookerji and Mr. Tata in recognition of their significant contributions and performance in 2025, above and beyond the normal course of their positions as Chief Financial Officer and General Counsel & Corporate Secretary, respectively. Mr. Mookerji was awarded a cash bonus in the amount of $214,000 in recognition of his significant contributions and efforts to automate and improve the Company's accounting processes and systems, in addition to his valuable assistance in negotiating a favorable legal settlement with respect to the previously disclosed litigation matter involving the Company's Guaymas, Mexico performance center. Mr. Tata was awarded a cash bonus in the amount of $50,000, in recognition of his instrumental role in overseeing and bringing the Guaymas litigation to a successful resolution. The Compensation Committee believes these one-time awards were appropriate in light of the substantial value each of Mr. Mookerji's and Mr. Tata's efforts provided to the Company and its shareholders, including the avoidance of additional litigation defense costs and potential further exposure that may have resulted in the absence of such settlement.

#### **Executive Summary and 2025 Performance Highlights** 
Ducommun had strong performance across all areas in 2025 despite the lower revenues in commercial aerospace mainly due to destocking and the Compensation Committee noted several significant achievements and milestones during the year, which are summarized below. No individual weightings were assigned to any one of these factors:

&nbsp;&nbsp;&nbsp;&nbsp;• On a year-over-year basis, Ducommun's market capitalization increased by
 51%, resulting in shareholders realizing almost $500 million in value in 2025 and demonstrating the effectiveness of the Company's
 pay-for-performance compensation philosophy in aligning executives' interests with those of shareholders.

• The Company's stock price increased by 49% on a year-over-year basis, rising from $63.66
 to $95.13 as measured on December 31, 2024 and December 31, 2025, respectively, providing substantial value to shareholders.

• Ducommun has seen year-over-year growth in total shareholder return since 2021, with a 40%
 higher cumulative total shareholder return in 2025 compared to the Russell 2000 index and a three-year relative total shareholder
 return at the 78<sup>th</sup>percentile, in each case, due to management's demonstrated track-record of strong operational
 leadership and effective cost management;

• For the third consecutive year, the Company established a new all-time revenue record of approximately
 $824.7 million with healthy year-over-year top line growth of almost 5% and surpassing the prior record of $786.6 million
 in 2024, as Ducommun continued to benefit from offloading with the right product portfolio, strong operating discipline and
 by leveraging its lean, highly focused performance center concept, with net revenue per employee increasing by approximately
 7% over the prior year all while overcoming challenges relating to workforce availability, inflationary pressures and continued
 headwinds in the commercial aerospace market.

• Management oversaw a very significant 180 bps increase in gross profit margins year-over-year,
 which is another great example of our operating process, Company culture, dedicated employees and strong leadership.

• In the third full year after announcing our VISION 2027 Strategy in December 2022, revenue
 from Ducommun's engineered products business accounted for 23% of its total sales with EBITDA margins at 16%, both of
 which are either running ahead of, or on track with the Company's VISION 2027 goals, and demonstrating management's
 solid progress towards the financial goals and key tenets of our value creation plan for shareholders.

&nbsp;&nbsp;&nbsp;&nbsp;• Management successfully grew the Company's defense business by 14% in 2025, driven by very strong
 performance in its missile franchise, which increased by 20% year-over-year, as well as:

&nbsp;&nbsp;&nbsp;&nbsp;• Increasing revenues from Ducommun's military fixed-wing aircraft business
 by 12% year-over-year;

• Growing the Company's rotary-wing aircraft business by 18% compared to the prior year;

• Overseeing the successful transition of Ducommun's Apache tail rotor business from its
 now-closed Monrovia, California facility to its Coxsackie, New York performance center, which was fully approved by Boeing
 for production;

• Ensuring the TOW missile was ready for full production at the Company's Guaymas, Mexico
 performance center; and

• Complementing the Company's missile portfolio with a very strong radar franchise, which
 grew by 32% over the prior year and which includes marquee programs such as the SPY-6 radar system, TPY-2 radar used on the
 THAAD missile defense system, and the G/ATOA radar system utilized by the U.S. Marine Corps.

&nbsp;&nbsp;&nbsp;&nbsp;• In 2025, the Company's net income decreased year-over-year basis due to
 one-time litigation settlement and related costs, net, of $83.3 million net of taxes, and in the absence of which would have
 improved to $57.5 million on an adjusted basis. The Company also attained records levels of Adjusted EBITDA, with three consecutive
 quarters above $30 million, growing from 14.8% of revenues in 2024 to approximately 16.4% in 2025, once again tracking well
 ahead of the 18% target in VISION 2027.

• Management also successfully sold the Company's Berryville, Arkansas operation in the
 second quarter of 2025 and has been actively marketing its Monrovia, California facility as it continues to execute on the
 Company's strategy of consolidating its rooftop footprint in contract manufacturing. Ducommun remains on target to achieve
 $11-$13 million in annual cost savings as articulated in our VISION 2027 strategy.

&nbsp;&nbsp;&nbsp;&nbsp;• Ducommun's remaining performance obligations grew across its commercial
 aerospace and defense businesses to a new record level of $1.1 billion, increasing by approximately 9% on a year-over-year
 basis, with growth across its commercial aerospace and defense businesses.

• Ducommun retaining its status as a U.S.-based manufacturer with U.S. employees and 95% of
 our revenue being produced in the U.S. The Company's only other non-U.S. facility is based in Guaymas, Mexico, which
 production constitutes less than 5% of our total revenue. Imports and exports to and from that facility have been covered
 under the U.S.M.C.A. to date, exempting the Company from the impact of tariffs.

The Compensation Committee incorporated these considerations into the final annual cash incentive awards, which recognized the significant individual and team performance that drove our results in 2025. Moreover, the Compensation Committee believes that our continued growth, with a 51% year-over-year increase in market capitalization, a 49% increase in stock price between December 31<sup>st</sup> of 2024 and 2025 and a three-year relative TSR in the 78<sup>th</sup> percentile compared to the Russell 2000 Index positions Ducommun and its shareholders favorably for further success going forward. Accordingly, for 2025, the target annual incentive award targets and annual cash incentive determination for each of the named executive officers are reflected in the table below.

**Weighting of Annual Incentive Plan Performance Goals for 2026**

For fiscal year 2026, the Compensation Committee recognized that in addition to operating income, the conversion of profit into cash flow is a critical metric that benefits shareholders since it not only demonstrates the quality of earnings but also serves as objective evidence of prudent management of the Company's working capital. Accordingly, the Compensation Committee revised the weighting afforded to the metrics under the 2026 annual incentive plan by increasing the weight of the cash flow from operations metric as depicted below:

![](ldco2026_def14ax66x3.jpg)

#### **Long-Term Incentives** 
In fiscal year 2024, Ducommun adopted the 2024 Stock Incentive Plan, pursuant to which we granted long-term incentives to our CEO in 2025 in the form of performance stock units with a three-year performance period that are based on earnings per share ("EPS") with a relative total shareholder return ("rTSR") modifier ("PSUs – EPS/rTSR") and revenue ("PSUs – Revenue" or "RPSUs"), and time-based restricted stock units that vest ratably in annual increments over three years ("RSUs"). Additionally, we granted long-term incentives to our other named executive officers in the form of PSUs – EPS/rTSR and RSUs. The allocation between the PSU – EPS/rTSR, RPSU and RSU components of the long-

term incentive awards to our CEO and PSUs – EPS/rTSR and RSUs to our other NEOs was determined after deliberations with the Compensation Committee involving the evaluation of multiple scenarios and considerations, including ensuring that our CEO's and other NEOs' long-term interests' remained aligned with those of shareholders and the desire to ensure the retention of our executive officers. We do not grant stock options, stock appreciation rights ("SARs") or similar option-like instruments to our named executive officers or other key employees or service providers, and accordingly, no such grants were issued to the aforementioned individuals within four days prior to, or one day after the release of any material non-public information. If in the future we anticipate granting stock options, SARs, or similar option-like instruments, we will establish a policy regarding how the Board determines when to grant such awards and how the Board or Compensation Committee will take material nonpublic information into account when determining the timing and terms of such awards.

The overall mix of long-term incentives granted to our NEOs in 2025, along with a breakdown of the applicable amount of PSUs, RPSUs and RSUs payable in shares of common stock are depicted below:

Issuing PSUs – EPS/rTSR to all of our NEOs and RPSUs to our CEO encourages our executives to focus on specific financial and other performance goals that the Compensation Committee believes will contribute to long-term shareholder value. Issuing RSUs to our NEOs provides a direct ownership interest in Ducommun and a long-term incentive for them to remain employed with us. Accordingly, PSUs – EPS/rTSR, RPSU and RSU awards are the only forms of long-term compensation afforded to our CEO, and PSUs – EPS/rTSR and RSUs are the only forms of long-term compensation afforded to our other NEOs since Ducommun does not maintain a pension plan for our executives.

In determining the aggregate value of long-term incentive grants in 2025, the Compensation Committee considered the results of the WTW compensation assessment as to the value of long-term incentives provided in accordance with published survey compensation data. In keeping with those considerations, the long-term incentive awards to our CEO and other named executive officers reflected a mix of performance- and time-based long-term incentives that were generally consistent with the market and prevailing business conditions and were intended to incentivize our executive officers to achieve the performance metrics thereunder. The Compensation Committee also considered the existing equity holdings of our NEOs and the number of shares both outstanding and available under our long-term incentive plans when granting awards in 2025.

The Compensation Committee made the following target long-term incentive awards to the named executive officers in 2025:

The target value of long-term incentives granted to our CEO in 2025 increased slightly, reflective of the 24%, or almost $180 million year-over-year increase in our market capitalization between 2023 and 2024, and our record level of revenue of $786.6 million in 2024 and 350 improvement in gross profit margins expansion between 2023 and 2024, and reflective of our philosophy of incentivizing performance in relation to the value realized by shareholders. The Compensation Committee believes the award of such long-term incentives is consistent with our pay-for-performance compensation philosophy and maintains the alignment between executives' interests and those of our shareholders by ensuring that the vast majority of our CEO's total target compensation is dependent on performance, thereby incentivizing continued increases in earnings, revenues and operating income, all to shareholders' benefit. The target value of the long-term incentives granted to our CEO and named executive officers over the past three years is depicted in the graphs below:

#### **CEO Revenue Performance Stock Unit Grant (FY2025-FY2027 Performance Period)** 
Based on the Company's continued growth as of the end of FY 2024, with a 24% year-over-year increase in market capitalization, a 22% increase in stock price between December 31<sup>st</sup> of 2023 and 2024 and a three-year relative TSR in the 79<sup>th</sup> percentile compared to the Russell 2000 Index, in 2025, our CEO was awarded RPSUs that may vest based upon the achievement of revenue targets, as depicted below, in the last year of a three-year performance period (from January 1, 2025, to December 31, 2027). Utilizing a three-year performance period requires our CEO to implement measures three years in advance to attain the revenue levels specific to the achievement of the performance metrics under the RPSU award, which aligns his performance with shareholders' interests. Based on our 2024 revenues of approximately $786.6 million when LTI goals were established, shareholders would realize a significant increase in value for our CEO to achieve the maximum payout at the end of the performance period of this award.

#### **Performance Stock Units – EPS/rTSR (FY2025-FY2027 Performance Period)** 
The performance-based long-term incentive awards granted in 2025 to our CEO and other NEOs, may be earned based upon the achievement of annual adjusted diluted EPS targets during each year of a three-year performance period, which is then subject to an rTSR modifier. The Compensation Committee chose adjusted diluted EPS as the performance metric to tie executive compensation directly to the annual and long-term growth in Ducommun's earnings. As depicted below, a rTSR modifier is then applied to the number of vested PSUs awarded to our CEO and other NEOs to further align executive compensation with shareholder value creation:

**Mechanics of Three-Year Performance Period PSU – EPS Grants with rTSR Modifier:**

![](ldco2026_def14ax69x1.jpg)

Accordingly, the PSUs granted in 2025 will cliff vest at the end of the three-year performance period in an amount between 0% and 200% of the target units as depicted below.

**Adjusted Diluted Earnings Per Share for Awards**

| | | | | | |
|:---|:---|:---|:---|:---|:---|
|  | **Adjusted Diluted EPS($)** | **Adjusted Diluted EPS($)** | **Adjusted Diluted EPS($)** | **Vesting Percentage of** | |
|  | **2025** | **2026** | **2027** | **Target Units for**<br> **Each Year** | **Three-Year**<br> **Total\*** |
| **Maximum** | 3.48 | 3.90 | 4.37 | 66.6% | 200% |
| **Target** | 3.30 | 3.49 | 3.70 | 33.3% | 100% |
| **Threshold** | 3.11 | 3.11 | 3.11 | 10.0% | 30% |

---

*\** *Assuming performance remains at the same level for all three years of the performance period.*

The Compensation Committee set the threshold and target adjusted diluted EPS levels to be consistent with our annual operating plan, with the target level increasing by approximately 6% each year over the three-year performance period, thereby ensuring management is incentivized to improve adjusted diluted earnings per share relative to the end of 2024.

In the event our performance falls between two of the data points listed in the table above, the percentage of target performance stock units that are earned will be determined by linear interpolation between the two data points, rounded to the nearest whole unit. Adjusted diluted EPS is calculated, as determined by the Compensation Committee, by adjusting our diluted EPS to reflect changes in accounting standards, discontinued operations to exclude gain or loss on the sale of any business or product line, and to reflect any asset impairment write-offs or charges (whether of goodwill, intangible or tangible assets), transaction-related costs or expenses (including but not limited to the effects of Financial Accounting Standards Board Accounting Standards Codification Topic 805), debt refinancing costs, and restructuring charges and other non-recurring expenses.

**Relative Total Shareholder Return Modifier (+/- 25%)**

After the end of the three-year performance period, our rTSR will be calculated and compared to the Russell 2000 Index for the same period. As depicted in the table below, the total number of PSUs earned will then be determined by multiplying the equity earned on the adjusted diluted EPS metric by a modifier between 0.75 and 1.25. Importantly, the rTSR modifier will not be greater than 1.0 unless our absolute total shareholder return over the three-year performance period is positive, regardless of our relative ranking. In total, the maximum funding for PSU awards based on the achievement of adjusted diluted EPS levels and application of the rTSR modifier cannot exceed 250% of target.

#### **Restricted Stock Unit Grants (FY2025-FY2027 Vesting Period)** 
The Compensation Committee approved the following grants of time-based RSU awards to our CEO and NEOs in 2025:

---

| | | |
|:---|:---|:---|
|  | **Number of Shares Granted** | **Grant Date Value of Shares ($)** |
| **Mr. Oswald** | 13443 | 774989 |

| **Ms. Gonzalez** | 2007 | 115704 |
| **Mr. Redondo** | 5505 | 317363 |
| **Mr. Tata** | 3431 | 197797 |

---

RSU grants vest in one-third increments over a period of three years and the grant date fair value of the awards in the table above was based on the closing price of $57.65 on March 5, 2025. The Compensation Committee believes that time-based RSU awards provide a direct ownership interest in Ducommun, thereby aligning their interests with those of shareholders, and serve the valuable purpose of helping to retain our NEOs and reward them for building their careers with the Company.

#### **Settlement of Awards from Prior Grant Cycles** 
**CEO Performance Restricted Stock Unit Grant (n/k/a Revenue Performance Stock Units) and Cash LTIP-Revenue FY2023-FY2025 Performance Period**

In 2023, our CEO was awarded performance restricted stock units ("2023 PRSUs") payable in shares and a long-term incentive cash award based on revenue ("Cash LTIP – Revenue") payable in cash, subject to vesting based upon the achievement of revenue targets in the last year of a three-year performance period (from January 1, 2023 to December 31, 2025) to incentivize the long-term growth of the business. The Compensation Committee determined the amount of revenue that was achieved relative to its strategic plan in the last year of the performance period and the percentage and number of the performance restricted stock units earned in shares and cash as a result thereof.

The revenue target for the performance period was established based on our 2022 revenues of $713 million, and the Compensation Committee contemplated that revenues would need to increase by approximately 16% for our CEO to achieve the maximum payout at the end of the performance period in 2025, the attainment of which would result in significant shareholder value. Since 2023, the Company's market capitalization increased by 87%, its stock price increased by 82% and as previously stated, the Company attained a three-year relative TSR in the 78<sup>th</sup> percentile compared to the Russell 2000 Index. The following table summarizes the original revenue targets as a percentage and dollar value at threshold, target and maximum performance levels and the resulting payout levels:

**CEO Revenue Goal Achievement (FY2023-FY2025 Performance Period)**

Despite achieving a new all-time revenue record of approximately $825 million, surpassing the prior record of $787 million in 2024, and increasing revenues by over 15% compared to 2022, the level of sales attained in the last year of the performance period fell just below the maximum level established under the 2023 grant for revenues. Consequently, 23,649 shares under the 2023 PRSU and an amount of $2,076,720 under the Cash LTIP – Revenue, reflecting 199% of the grant award, were issued to our CEO based on linear interpolation.

**Performance Stock Units and Long-Term Incentive Cash Awards based on EPS/rTSR (Cash LTIPs – EPS/rTSR) FY2023-FY2025 Performance Period**

The three-year performance period for performance stock units and Cash LTIPs – EPS/rTSR awarded in 2023 ended on December 31, 2025. Since the beginning of the performance period in 2023, the Company's market capitalization increased by 87%, its stock price increased by 82% and as previously stated, attained a three-year relative TSR in the 78<sup>th</sup> percentile compared to the Russell 2000 Index. The threshold, target, and maximum performance levels for performance stock units and Cash LTIPs awarded in 2023, and the actual performance in each of the years 2023 to 2025, were as follows:

**Adjusted Diluted EPS ($) and rTSR Modifier for Performance Stock Unit Determination**

|  |  | **Total shares awarded (%)** | **Total shares awarded (%)** | **Total shares awarded (%)** | **217%** |

Our relative total shareholder return compared to the Russell 2000 Index was at the 78<sup>th</sup> percentile, generating a payout multiple of 1.15 and therefore, the number of total shares earned was adjusted due to the impact of the modifier based on our adjusted diluted EPS of $4.21 a share, which was used solely for determining our performance under the 2023 PSU grant, and was a significant increase in shareholder value when compared to the beginning of the performance period.

**Timing of Long-Term Incentive Awards**

The Compensation Committee has implemented a process whereby all normal cycle long-term incentives are awarded in the spring of each year, and long-term equity incentive grants in 2025 were generally consistent with this practice. However, long-term incentive grants may be made at other times in the event of the hiring of a new executive officer or a special award to recognize individual performance. In addition, the timing of the award of normal cycle long-term equity incentives may be changed in the future as needed to meet changing circumstances.

#### **Severance and Change in Control Agreements and Practices** 
In 2024, we entered into new key executive severance agreements (collectively, the "Key Executive Severance Agreements") with each of our named executive officers. These agreements (which are all substantially the same) provide for cash severance, double-trigger equity acceleration and certain continued benefits if there is a qualifying termination in connection with a change in control, and limited cash severance and continued benefits if there is a qualifying termination outside the context of a change in control. We entered into severance agreements with our NEOs in order to bring them current with, and reflective of, current market practices. Moreover, Key Executive Severance agreements are necessary for the recruitment and retention of qualified executives. We believe having severance arrangements in place allows our NEOs to focus on shareholder interests when considering strategic alternatives because they provide some financial security in the event of an involuntary termination of employment. We do not provide gross ups for taxes under these agreements. Please refer to the section entitled "Potential Payments Upon Termination or Change in Control" below for further discussion of the Key Executive Severance Agreements.

#### **Second Amended and Restated Clawback Policy** 
In August 2025, we adopted a Second Amended and Restated Clawback Policy consistent with the listing standards adopted by the New York Stock Exchange in light of the SEC's adoption of the "Listing Standards for Recovery of Erroneously Awarded Compensation" pursuant to Section 10D of the Securities and Exchange Act of 1934. The second amended clawback policy applies in the event: (i) of an accounting restatement that is material to previously issued financial statements; or (ii) of an error that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period, and is necessitated due to material noncompliance with financial reporting requirements under

U.S. generally accepted accounting principles or SEC rules. In the event of such a restatement, all incentive-based compensation earned by our current or former executive officers may be recovered to the extent that such payments and vested amounts were higher than they would have been based on corrected financial statements, and, at the discretion of the Compensation Committee, any amount of time-based equity compensation may also be recovered, in each case, for such compensation received in the three completed fiscal years preceding the date the restatement is required to be prepared. The clawback of time-based equity compensation received during the three-year fiscal period is limited to the compensation the individual received while serving as an executive officer.

#### **Securities Trading Policy and Prohibition on Pledging and Hedging** 
The Company has an insider trading policy ("Insider Trading Policy") governing the purchase, sale and other dispositions of the Company's securities that applies to directors, officers and employees, and to the Company itself in the repurchase of its own securities. We believe our Insider Trading Policy and repurchase procedures are reasonably designed to promote compliance with insider trading laws, rules and regulations, and the listing standards applicable to the Company. A copy of the Insider Trading Policy was filed as Exhibit 19.1 to the Company's Annual Report on Form 10-K for the year ended December 31, 2024.

To align the interests of our directors, officers, and employees, including our named executive officers, with our shareholders, our Insider Trading Policy does not permit any director, officer, or employee of Ducommun to either margin or pledge Company securities as a loan or to engage in any hedging transactions involving our securities. Hedging includes the purchase or sale of financial instruments that are designed to hedge or offset any decrease in the market value of securities, including prepaid variable forward contracts, equity swaps, collars, and exchange funds.

#### **Other Compensation** 
We provide or make available certain other compensation and personal benefits to the named executive officers, including the ability to participate in a non-qualified deferred compensation plan and an automobile allowance, as well as medical, dental, life and other insurance benefits. In addition, the named executive officers receive 401(k) matching contributions and are eligible to participate in our Employee Stock Purchase Plan on the same basis as our other employees. We do not provide any pension or supplemental retirement benefits to our named executive officers. Please refer to the section entitled "2025 Nonqualified Defined Contribution and Other Nonqualified Deferred Compensation Plans" below for further discussion of our non-qualified deferred compensation plan.

#### **Director and Officer Stock Ownership Policy** 
In August 2020, the Compensation and Corporate Governance and Nominating Committees of the Board adopted a stock ownership policy that requires our NEOs to acquire and hold shares of our stock equal in value to a multiple of their annual base salary as follows:

---

| | | |
|:---|:---|:---|
|  | **Stock Ownership Guidelines** |  |
| **Position** | **Ownership Requirements** | **Current Holdings** |
| **Chief Executive Officer** | 5x Base Salary | > 30 times Base Salary\* |
| **Other NEOs** | 3x Base Salary | Average of 7.0 times Base Salary |

---

*\** *Includes holdings from both personal investments and Company long term incentive awards.*

Under the policy, each NEO's stock ownership will be valued based on the average trading price of Ducommun's stock over a twelve-month period ending on December 31<sup>st</sup> of each year. Executive officers have five years from their initial election to the position covered by the policy to satisfy its requirements and an NEO is deemed to remain in compliance provided that non-compliance is not due to the sale of securities. In the event an NEO is not in compliance with the policy's requirements, they are expected to retain 100% of any net equity awards (i.e. net of the cost of exercise for stock options and net of withholding taxes for all awards) and refrain from divesting any Company stock until re-attainment of the applicable holding requirement. For purposes of determining compliance with the policy, an NEO's stock ownership is determined by multiplying the aggregate number of shares owned and unvested PSUs and RSUs by the average trading price of our stock over a twelve-month period ending on December 31<sup>st</sup> of each calendar year, divided by the NEO's annual base salary as reported in Ducommun's 2025 proxy statement. All of the named executive officers are either in compliance, or have additional time in which to comply, with the stock ownership guidelines as of December 31, 2025.

#### **Compensation Risk Assessment** 
The Compensation Committee reviews the risks associated with our compensation policies and practices for executive officers and employees generally. The Compensation Committee did not identify any risks arising from these policies and practices that are reasonably likely to have a material adverse effect on the Company. In the course of its review, the Compensation Committee considered various features of our compensation policies and practices that discourage excessive risk taking, including those outlined below.

---

| | |
|:---|:---|
| **Compensation Feature** | **Compensation Practices** |
| **Philosophy** | An appropriate compensation philosophy based on our proxy talent peer group, pay for performance and other market compensation data. |
| **Balanced Approach** | • An effective balance between cash and equity-based compensation.<br> • An appropriate mix of short- and long-term performance measures, capped by maximum payouts under annual cash incentive, PSU – EPS/rTSR and RPSU programs.<br> • Multi-year vesting periods for long-term stock awards.<br> • An appropriate mix of time- and performance-based vesting schedules.<br> • Financial measures as well as discretion to recognize individual performance capped by a maximum limit on long-term incentive awards. |
| **Alignment of Interests with Shareholders** | Stock ownership guidelines for NEOs and non-employee directors. |
| **Perquisites and Retirement Benefits** | Limited perquisites and retirement benefits. |

---

#### **Tax Deductibility and Gross-Ups** 
Section 162(m) of the Internal Revenue Code places a limit of $1 million on the amount of compensation that we may deduct as a business expense in any year with respect to certain of our most highly paid executive officers. While the Compensation Committee considers the deductibility of compensation as one factor in determining executive compensation, it believes that it is in the best interests of our shareholders to maintain flexibility in our approach to executive compensation and to structure a program that we consider to be the most effective in attracting, motivating and retaining key executives.

The double-trigger severance payments that our NEOs could receive in connection with a change in control (described in the section above entitled "Severance and Change in Control Agreements and Practices") could subject an NEO to an excise tax on an "excess parachute payment" under Internal Revenue Code Section 4999. Ducommun does not provide any gross-up to its executives for any excise tax due under this section of the Internal Revenue Code.

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Please note that RPSU awards are synonymous with previously issued PRSU awards and were renamed under the 2024 Stock Incentive Plan.* 

*(2)* *The stock options became exercisable in increments on the anniversary date of the date of grant such that for stock options granted in 2019, one-third vested and became exercisable in each of 2020, 2021 and 2022 and for stock options granted in 2018, one-third vested and became exercisable in each of 2019, 2020 and 2021.* 

*(3)* *The unvested restricted stock units vest as follows: (i) with respect to grants in 2023, one-third vested in each of 2024 and 2025, and one-third will vest in 2026; (ii) with respect to grants in 2024, one-third vested in 2025, and one-third will vest in each of 2026 and 2027; and (iii) with respect to grants in 2025, the award will vest in equal installments of one-third in each of 2026, 2027 and 2028.* 

*(4)* *All performance stock units (including RPSUs f/k/a PRSUs) are shown based on our actual achievement of performance measures for periods through 2025 and at the maximum number of shares eligible to vest for performance periods that end after 2025. The performance stock units will vest if the performance conditions are met as follows: (i) grants in 2023 vested based on achievement of the performance metrics on December 31, 2025 and were settled in the first quarter of 2026, (ii) grants in 2024 will vest, if at all, based on achievement of the performance metrics on December 31, 2026 and will be settled in the first quarter of 2027, and (iii) grants in 2025 will vest, if at all, based on achievement of the performance metrics on December 31, 2027 and will be settled in the first quarter of 2028.* 

*(5)* *The amounts for RPSUs f/k/a PRSUs and PSUs are calculated by multiplying the number of unvested RPSUs, PRSUs and PSUs, respectively, by the closing price of our common stock on the NYSE on the last trading day of 2025 ($95.13).*

We offer a nonqualified defined contribution and nonqualified deferred compensation plan (the "Plan") to certain members of our management, including the named executive officers. Under the Plan, Participants may elect to defer up to 80% of their annual base salary and 100% of their annual incentive, RSU and PSU grants, and may allocate the balance credited to their accounts among various investment crediting options available under the Plan. The Plan administrator has discretion to determine which crediting options will be available under the Plan. Participant accounts are adjusted daily to reflect the performance of the applicable crediting options. Participants may elect to receive all or a portion of any Plan year's deferral balance while they are still employed by Ducommun under various conditions as set forth in the Plan. Participants who separate from Ducommun will have their deferral balances paid within ninety (90) days after their employment ends, unless specific retirement guidelines are met. Participants who meet our retirement guidelines can elect to have their distributions made in either a lump sum or in two- to ten annual installments, depending on the payment method selected. Participants with deferred amounts less than $100,000 will be paid out in a lump sum upon the cessation of their employment with Ducommun. Scheduled in-service distributions are also paid in a lump sum. If a participant terminates prior to or while receiving a scheduled in-service distribution, or if a participant has elected to have the deferral balance paid after employment ends, the distribution will be paid (or installments will commence) in the month following separation from service. However, for certain specified employees, post-employment distributions generally cannot be paid until six months after separation of service, except in the event of death. Additionally, limited portions of a participant's account may be distributed in accordance with the Plan in the event the participant suffers a sudden, unexpected and severe financial hardship. On an annual basis we may credit additional amounts under the Plan on behalf of eligible employees in an amount equal to: (i) the 10 Year U.S. Treasury Bill Rate plus three hundred basis points based on participants' annual contributions to the Plan; and (ii) a maximum of $100,000 regardless of participants' contributions to the Plan. The table below summarizes participants' and the registrant's contributions to the Plan for 2025:

### **Potential Payments Upon Termination or Change in Control** 
As discussed above, we entered into Key Executive Severance Agreements with each of our NEOs in 2024. The Key Executive Severance Agreements provide that if a change in control (as defined below) of Ducommun occurs and there is qualifying termination of employment (as defined below) of the NEO within the three months prior to or 24 months following that change in control, the named executive officer will be entitled to receive payment in a single lump sum of an amount equal to the sum of (i) two times the annual base salary of the named executive officer prior to the change in control (or two and one-half times in the case of our CEO), and (ii) two times the target annual cash incentive of the executive officer under our annual cash incentive plan in effect during the year in which the change in control occurs (or two and one-half times in the case of our CEO). Further, with respect to long-term equity incentive awards granted to such named executive officers, (x) stock options become fully exercisable immediately for the full term of the options, (y) performance stock units become vested immediately based on our actual achievement of performance measures for periods through the date of termination of employment and at the target number of shares for periods after the date of termination of employment, and (z) restricted stock units vest immediately, provided that in all cases, the named executive officer complies with certain confidentiality and non-disparagement restrictive covenants. Additionally, the named executive officers shall be entitled to receive the continuation of certain benefits for a period of two years (or two and one-half years in the case of our CEO), including medical, life, disability and other insurance benefits as are provided to other executives of Ducommun. The continuation of these benefits shall be subject to reduction in the event that the named executive officer obtains employment during the two-year period (or two and one-half years in the case of our CEO) if the respective named executive officer is eligible to receive such insurance benefits under another employer's plans.

As used herein, a change in control of Ducommun is generally deemed to have occurred in the event of certain tender offers, mergers or consolidations, the sale, exchange or transfer of substantially all of our assets, the acquisition by a person or group of certain percentages of our outstanding voting securities, the consummation of a plan of liquidation or dissolution of Ducommun, or certain changes in the members of the Board.

The Key Executive Severance Agreements also provide that if there is a qualifying termination of employment of the named executive officer at any time other than in connection with a change in control of Ducommun as described above, the named executive officer shall be entitled to receive (i) payment of his or her full salary for a period of one year (or, two years in the case of the CEO), together with payment of the amount of any annual cash incentive for a past year that has not yet been paid, (ii) a payment of an amount equal to the named executive officer's target annual bonus under the Company's annual cash incentive program in effect during the year in which the qualifying termination occurs and (iii) continuation of benefits (as described above) for a period of one year (or, two years in the case of the CEO), provided that in all cases, the named executive officer complies with certain confidentiality and non-disparagement restrictive covenants.

A qualifying termination of employment includes any termination of the NEO's employment by the Company other than a termination for cause, except due to the NEO's death or disability. Termination for cause is generally defined in the key executive severance agreements as termination by Ducommun upon (i) the willful and continued failure by the executive to substantially perform his or her duties with Ducommun other than any such failure resulting from the executive's incapacity due to physical or mental illness, after a demand for substantial performance is delivered to the executive by the chief executive officer or the Compensation Committee that specifically identifies the manner in which the executive has not substantially performed his or her duties, or (ii) the willful engaging by the executive in misconduct that is materially injurious to Ducommun, monetarily or otherwise, and that constitutes common law fraud or a felony on the part of the executive. For purposes of this definition, no act or failure to act on the part of an executive, is considered "willful" unless done, or omitted to be done, by the executive not in good faith and without reasonable belief that the action or omission was in the best interest of Ducommun or its subsidiaries. In the event of a material diminution in an executive's authorities, duties, or responsibilities, a reduction of 5% or more in the executive's base salary, a material change in the executive's geographic location at which the executive is required to perform services, or other events as described in the key executive severance agreements, then the executive will have the right, after a 90-day cure period pursuant to the terms and conditions of the Key Executive Severance Agreement, to terminate his or her employment and such termination will be a qualifying termination of employment.

If a change in control of Ducommun occurs and there is a qualifying termination of employment of a named executive officer within the three months prior to or 24 months following the change in control of Ducommun, the named executive officer would receive the amounts in the table below in the column "Qualifying Termination of Employment in Connection with Change in Control." If there is a qualifying termination of employment of the named executive officer outside of the change in control period, the named executive officer would receive the amounts in the table below in the column "Qualifying Termination of Employment Outside of Change in Control Period." The information in the table below assumes that a triggering event occurred on December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *The amount of salary continuation for the CEO during the change in control period is equal to two and one-half times his base salary and outside the change in control period is equal to two times his base salary, each as in effect on December 31, 2025. The amount of salary continuation for the other NEOs during the change in control period is equal to two times the NEOs base salary and outside the change in control period is equal to the NEO's base salary.* 

*(2)* *The amount included in the Bonus row for the CEO during the change in control period is equal to two and one-half times his target annual bonus and outside the change in control period is equal to his target annual bonus, each as in effect on December 31, 2025. The amount included in the Bonus row for the NEOs during the change in control period is equal to two times the NEOs' target annual bonus and outside of the change in control period is equal to the NEO's target annual bonus.* 

*(3)* *The amounts for PSUs are calculated based on the number of unvested PSUs, RPSUs (f/k/a PRSUs) payable in shares and the closing price of our common stock on the NYSE on the last trading day of 2025 ($95.13). The number of unvested PSUs includes Cash LTIPs – EPS/rTSR and has been calculated based on our actual achievement of performance measures for periods through year-end 2025 plus the target number of shares for periods after year-end 2025. PSUs granted in 2023 are not included since they are considered to be fully vested at December 31, 2025.* 

*(4)* *The amounts for RSUs are calculated based on the number of unvested RSUs and the closing price of our common stock on the NYSE on the last trading day of 2025 ($95.13).*

### **Pay Ratio Disclosure** 
Mr. Oswald's 2025 annual total compensation was $10,329,989, and the 2025 annual total compensation of the median compensated employee as of December 31, 2025, other than our CEO, Stephen G. Oswald, was $83,227. The ratio of these amounts was 124-to-1.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on payroll records and the methodology described below. For these purposes, we identified the median compensated employee using base annual pay, excluding overtime, for calendar year 2025, for all full-time, part-time, seasonal and temporary workers as of December 31, 2025. Base annual pay, excluding overtime, was annualized for any permanent employee who did not work for the entire year. As a result, we used an employee population of 2,129 for purposes of determining the compensation of our median employee.

The SEC's rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above.

### **Pay Versus Performance Table** 
The Pay Versus Performance Table, associated narratives and other tables which follow, describe how compensation actually paid to our Named Executive Officers aligns to our financial performance for the years ended December 31, 2025, 2024, 2023, 2022, and 2021, as required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K.

The year-over-year increase in Compensation Actually Paid is reflective of the impact of the approximately 50% year-over-year growth in the Company's market capitalization and stock price on outstanding and unvested equity awards held by our PEO, both of which greatly benefit shareholders.***

The dollar amounts do not reflect the actual amount of compensation earned by or paid during the applicable year. As our PEO does not participate in any defined benefit plans, no adjustments were required to amounts reported in the Summary Compensation Table related to the value of benefits under such plans.

*(b)* *The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: (i) the year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year; (ii) the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year; (iii) for awards that are granted and vest in the same applicable year, the fair value as of the vesting date; (iv) for awards granted in prior years that vest in the applicable year, the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value; (v) for awards granted in prior years that are determined to fail to meet the applicable vesting conditions during the applicable year, a deduction for the amount equal to the fair value at the end of the prior fiscal year; and (vi) the dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. The amounts deducted or added in calculating the equity award adjustments are as follows:*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(c)* *In accordance with SEC rules, the amount in this column for each covered year has been calculated by subtracting the amount reported in the "Reported Value of Equity Awards" column for such covered year from the amount reported in the "Reported Summary Compensation Table Total for PEO" column for such covered year and then adding to such figure the amount reported in the "Equity Award Adjustments" column for such covered year.*

As our Non-PEO NEOs do not participate in any defined benefit plans, no adjustments were required to amounts reported in the Summary Compensation Table totals related to the value of benefits under such plans. In accordance with the SEC rules, the following adjustments were made to average total compensation for the Non-PEO NEOs as a group for each year to determine the compensation actually paid, using the same methodology described above in Note 2:*

Please note that exclusive of AeroVironment, Inc. and Kratos Defense & Security Solutions, the 5-Year TSR for the median of our Proxy Talent Peer Group would have totaled $162.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(8)* *The proxy talent peer group used to determine 2024 and 2023 compensation for our PEO and Non-PEO NEOs included: AAR Corporation, AeroVironment, Inc., Astronics Corporation, Barnes Group, Inc., CIRCOR International, Inc., Heico Corporation, Hexcel Corporation, Kaman Corporation, Kratos Defense & Security Solutions, Inc., Mercury Systems, Inc., RBC Bearings, Inc. and Triumph Group, Inc.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(9)* *The proxy talent peer group used to determine 2022 compensation for our PEO and non-PEO NEOs included: AAR Corporation, Astronics Corporation, Barnes Group, Inc., CIRCOR International, Cubic Corporation, HEICO Corporation, Hexcel Corporation, Kaman Corporation, Kratos Defense & Security Solutions, Inc., Mercury Systems, Inc., RBC Bearings, Inc.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(10)* *The proxy talent peer group used to determine 2021 compensation for our PEO and non-PEO NEOs included: AAR Corp., Aerojet Rocketdyne Holdings, Inc., Astronics Corporation, Barnes Group Inc., CIRCOR International, Inc., Cubic Corporation, Heico Corporation, Kaman Corporation, Kratos Defense & Security Solutions, Inc., Mercury Systems, Inc. and RBC Bearings Incorporated.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(11)* *2025 Net Income includes $83.3 million, net of taxes, related to the litigation settlement and related costs, net associated with the one-time and previously disclosed litigation matter involving our Guaymas, Mexico performance center. Ducommun's 2021 Net Income excludes $102.8 million, net of taxes, attributable to Ducommun's completion of a sale-leaseback transaction involving its Gardena, CA performance center.* 

&nbsp;&nbsp;&nbsp;&nbsp;*(12)* *2025 Operating Income includes $107.3 million, of litigation settlement and related costs, net associated with the one-time and previously disclosed litigation matter involving our Guaymas, Mexico performance center. Operating income decreased between 2022 and 2023 due to $11.9 million in restructure expenses related to the repositioning of production at three of our performance centers in conjunction with our 2022 restructure plan to enhance the cost structure of our operations.* 

As described in more detail above in our "2025 Compensation Discussion and Analysis", we use various measures to align the compensation of our named executive officers with Company performance.

The following tabular list identifies, in alphabetical order, the financial measures we have determined to be the most important to link compensation actually paid to both our PEO and NEOs for the most recently completed fiscal year:

Cash Flow from Operations Net Revenue <br> Diluted Earnings per Share Operating Income <br> <u>Net Income</u>  

Not all of these measures are presented in the Pay versus Performance table. The Company has generally sought to incentivize long-term performance, and therefore has not specifically aligned the Company's performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year.

In accordance with such rules, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.

The graphs below illustrate our TSR compared to our proxy talent peer group's TSR over the period 2021 to 2025:

As the above graphs illustrate, Ducommun's TSR either outperformed or remained comparable to that of its proxy talent peer group over four of the past five years over period covered by the Pay versus Performance Table, despite the changes to our proxy talent peer group in each of 2021, 2022 and 2023. In addition, the Compensation Actually Paid to our PEO was proportionately aligned with the Company's TSR over the same prior five-year period.

The graph below illustrates the relationship between our net income, operating income and compensation actually paid to our PEO and non-PEO NEOs on a GAAP basis which, in the case of our net income and operating income, includes an expense of $83.3 million, net of taxes, and $107.3 million, respectively, related to the litigation settlement and related costs, net associated with the previously disclosed litigation matter involving the Guaymas, Mexico performance center. Despite the negative impact on the Company's net income and operating income metrics in 2025, the settlement charge is non-recurring in nature, and the Company does not expect any further financial impact from this matter, since the settlement fully resolved the underlying claims.

As illustrated in the graph below, excluding one-time litigation settlement and related costs, net, of $83.3 million net of taxes, reveals that Ducommun's adjusted net income increased by approximately 80% over the prior year and adjusted operating income increased by approximately 65% on a year-over-year basis, yielding a more useful comparison between the Company's performance and compensation actually paid to our PEO and non-PEO NEOs. **Led by our PEO, Mr. Oswald, our Chief Financial Officer, General Counsel and members of our Board of Directors, the Company made the prudent decision to settle the Guaymas litigation rather than continue to incur defense costs and potentially expose Ducommun and its shareholders to negative publicity and further liability that may have resulted had the matter gone to trial. Viewed in this manner, the compensation actually paid to our PEO and non-PEO NEOs in 2025 is more reflective of the Company's underlying performance, including the growth in the Company's adjusted net income and adjusted operating income, the year-over-year increase in market capitalization of approximately $480 million, an almost 50% increase in stock price, and all-time high revenues in 2025, all of which were consistent with, and reinforce, our pay for performance compensation philosophy.**

## **Proposal 3 Ratification of the Selection of Independent Registered Public Accounting Firm** 
The Audit Committee has selected PricewaterhouseCoopers LLP ("PwC") as Ducommun's independent registered public accounting firm for the year ending December 31, 2026. Neither Ducommun's Certificate of Incorporation nor its Bylaws require that shareholders ratify the selection of PwC as Ducommun's independent registered public accounting firm. However, we are requesting ratification because we believe it is a matter of good corporate practice.

If Ducommun's shareholders do not ratify the selection, the Audit Committee will reconsider whether or not to retain PwC, but may nonetheless retain PwC as Ducommun's independent registered public accounting firm. Even if the selection is ratified, the Audit Committee in its discretion may change the appointment at any time if it determines that such change would be in the best interests of Ducommun and its shareholders. A representative of PwC plans to attend the Annual Meeting. That individual will have an opportunity to make a statement and will be available to respond to appropriate questions from shareholders.

### **Independent Registered Public Accounting Firm** 
PwC has served as Ducommun's independent registered public accounting firm since 1989, and the Audit Committee has selected PwC as Ducommun's independent registered public accounting firm for the year ending December 31, 2026. PwC has unrestricted access to the Audit Committee to discuss audit findings and other financial matters.

### **Recommendation to Appoint PwC as Independent Registered Public Accounting Firm** 
PwC has been Ducommun's auditor since 1989. As in prior years, the Audit Committee undertook a review of PwC in determining whether to select PwC as Ducommun's independent registered accounting firm for 2026 and to recommend ratification of that firm's selection to our shareholders. In that review, the Audit Committee considered a number of factors including:

&nbsp;&nbsp;&nbsp;&nbsp;• Continued independence of PwC;

• Length of time PwC has been engaged by Ducommun;

• Senior management's assessment of PwC's performance;

• Audit and non-audit fees;

• Capacity to appropriately staff the audit;

• Geographic and subject-matter coverage;

• Lead Audit Engagement Partner performance;

• Overall performance;

• Qualifications and quality control procedures; and

• Whether retaining PwC is in the best interests of Ducommun.

Based on this review, the Audit Committee believes that PwC is independent and that it is in the best interests of Ducommun and our shareholders to retain PwC to serve as our independent registered public accounting firm for 2026. The Audit Committee believes there are significant benefits to having an independent auditor with an extensive history with Ducommun. These include:

&nbsp;&nbsp;&nbsp;&nbsp;• Higher quality audit work and accounting advice due to
 PwC's institutional knowledge of our business and operations, accounting policies and financial systems, and internal
 control framework; and

• Operational efficiencies and a resulting lower fee structure because
 of PwC's history and familiarity with our business.

In accordance with the Sarbanes-Oxley Act and related SEC rules, the Audit Committee limits the number of consecutive years an individual partner may serve as the lead audit engagement partner to Ducommun to five years. The current lead audit engagement partner was in his fifth year in that role in 2025 with a new lead audit engagement partner in 2026.

#### **Policy for Pre-Approval of Independent Accountant Services** 
The Audit Committee recognizes the importance of maintaining the independence of our independent auditor, both in fact and appearance, and takes a number of measures to ensure independence. The Audit Committee has established a policy pursuant to which all services, audit and non-audit, provided by the independent auditor must be pre-approved by the Audit Committee or its delegate. For audit services, the independent accountant provides the Audit Committee with an engagement letter outlining the scope of audit services to be performed in connection with the year-end audit, the quarterly financial statement reviews for the three quarters of the following year and other audit-related services (which are services that are reasonably related to the performance of the audit or review of our financial statements), and the proposed fees related thereto. If approved by the Audit Committee, this engagement letter is formally signed by the chairman of the Audit Committee acting on behalf of the Audit Committee.

For non-audit services, our management submits to the Audit Committee for approval each year a schedule of non-audit services that it recommends the Audit Committee engage the independent accountant to provide in connection with the year-end audit and during the following year. The schedule includes a description of the planned non-audit services and an estimated budget for such services. In order to promptly handle unexpected requirements, the Audit Committee has delegated to the Chair of the Audit Committee the authority to amend, supplement or modify the schedule of approved permissible non-audit services. The Chair of the Audit Committee reports any such actions taken to the Audit Committee at its next meeting.

The Audit Committee pre-approved 100% of the aggregate fees of the independent registered public accounting firm for 2025 and 2024.

### **Audit Committee Report** 
As of the time of this Report, the Audit Committee is made up of four non-employee directors, all of whom are "independent" under applicable listing standards of the NYSE and applicable SEC rules. The Audit Committee is governed by a written charter, which has been adopted by the Board. A copy of the current Audit Committee charter is available on Ducommun's website at *https://www.ducommun.com* in the Corporate Governance section of the Investor Relations webpage.

Ducommun's management is responsible for the preparation, presentation and integrity of the consolidated financial statements, maintaining a system of controls, and having appropriate accounting and financial reporting principles and policies. The independent registered public accounting firm is responsible for planning and carrying out an audit of the consolidated financial statements and an audit of internal controls over financial reporting in accordance with the rules of the Public Company Accounting Oversight Board ("PCAOB") and expressing an opinion as to the consolidated financial statements' conformity with U.S. generally accepted accounting principles ("GAAP") and as to our internal controls over financial reporting. The Audit Committee monitors and oversees these processes and is responsible for selecting and overseeing Ducommun's independent registered public accounting firm.

As part of the oversight process, the Audit Committee met five times during 2025. Throughout the year, the Audit Committee met with PwC, management, and the internal auditor, both together and separately in closed sessions. In the course of fulfilling its responsibilities, the Audit Committee did, among other things, the following:

&nbsp;&nbsp;&nbsp;&nbsp;• Reviewed and discussed with management and PwC Ducommun's consolidated financial
 statements for the year ended December 31, 2025, and the quarters ended March 29, 2025, June 28, 2025, and September 27, 2025;

• Oversaw and discussed with management Ducommun's review of internal controls over financial
 reporting;

• Reviewed management's representations that Ducommun's consolidated financial statements
 were prepared in accordance with GAAP and fairly present Ducommun's results of operations and financial position;

• Discussed with PwC the matters required to be discussed by the applicable requirements of
 the PCAOB and the SEC;

• Received the written disclosures and letter from PwC required by applicable PCAOB requirements
 regarding PwC's communications with the Audit Committee concerning independence, and discussed with PwC the latter's
 independence;

• Considered whether the provision of non-audit services by PwC to Ducommun is compatible with
 maintaining PwC's independence;

• Monitored the Ethics Point reporting system implemented to provide an anonymous complaint
 reporting process;

• Reviewed the scope of and overall plans for the annual audit and the internal audit program;

• Reviewed new accounting standards applicable to Ducommun with the Chief Financial Officer,
 internal audit department and PwC;

• Consulted with management and PwC with respect to Ducommun's processes for risk assessment
 and risk mitigation;

• In conjunction with the Board, reviewed the public disclosure of Ducommun's cybersecurity
 and data privacy risks and policies and controls designed to mitigate such risks;

• Reviewed the implementation and effectiveness of Ducommun's ethics and compliance program,
 including processes for monitoring compliance with applicable laws, Company policies, and Ducommun's Code of Business
 Conduct and Ethics; and

• Reviewed and discussed with management its assessment and report on the effectiveness of Ducommun's
 controls over financial reporting as of December 31, 2025, which it made based on criteria established in the Internal Control-Integrated
 Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework).

The Audit Committee has reviewed and discussed with PwC its review and report on Ducommun's internal controls over financial reporting as of December 31, 2025. Based on the foregoing review and discussions described in this report, the Audit Committee recommended to the Board, and the Board has approved, that the audited financial statements be included in Ducommun's Annual Report on Form 10-K for the year ended December 31, 2025, for filing with the Securities and Exchange Commission.

Submitted by the Audit Committee,

Samara A. Strycker–Committee Chair

Richard A. Baldridge

Daniel L. Boehle

Daniel G. Korte

The above report of the Audit Committee shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933 or under the Securities Exchange Act of 1934, except to the extent that Ducommun specifically incorporates this information by reference, and shall not be deemed filed under such Acts.

## **Proposal 4 Approval of Amended and Restated Ducommun Incorporated 2024 Stock Incentive Plan** 

### **Introduction** 
On March 12, 2026, the Board of Directors unanimously adopted and approved an amendment to and restatement of the 2024 Stock Incentive Plan (the **"Amended and Restated 2024 Stock Plan"**) and is submitting the Amended and Restated 2024 Stock Plan to shareholders for their adoption and approval at the 2026 Annual Meeting. Upon approval by our shareholders, the Amended and Restated 2024 Stock Plan would amend and restate our shareholder-approved 2024 Stock Incentive Plan (the **"Current Plan"**). The Amended and Restated 2024 Stock Plan would, among other things, increase the number of shares available for issuance pursuant to the Current Plan by 619,595 shares and increase the duration of the term through the ten-year anniversary of the adoption of the Amended and Restated 2024 Stock Plan by the shareholders. The Board of Directors believes our interests are best advanced by providing equity-based incentives to certain individuals responsible for our long-term success by encouraging such persons to remain in the service of Ducommun and to align the financial objectives of such individuals with those of our shareholders.

The Current Plan is the only active stock incentive plan under which Ducommun can grant equity-based compensation awards. Because Ducommun anticipated that its equity-based compensation needs would soon exceed the remaining shares available under the Current Plan, the Board of Directors of Ducommun adopted the Amended and Restated 2024 Stock Plan. The table below gives information about Ducommun's common stock that may be issued upon the exercise of options and vesting of restricted stock units and performance stock units under all of Ducommun's equity compensation plans as of December 31, 2025. The table therefore includes the following plans: the Amended and Restated 2024 Stock Plan and the Current Plan. There are no outstanding awards under equity compensation plans not approved by shareholders.

---

| | |
|:---|:---|
| &nbsp;&nbsp;New shares being authorized under the Amended and Restated 2024 Stock Plan | 619595 |
| &nbsp;&nbsp;Stock options outstanding | 105784 |
| &nbsp;&nbsp;Weighted average exercise price | $38.79 |
| &nbsp;&nbsp;Weighted average remaining contractual life of stock options | 3.1 years |
| &nbsp;&nbsp;Restricted Stock Units outstanding (unvested) | 273409 |
| &nbsp;&nbsp;Performance Stock Units outstanding (unvested) | 326301 |
| &nbsp;&nbsp;Shares remaining for grant under the Current Plan | 198163 |
| &nbsp;&nbsp;**Total number of shares available for future awards after April 29, 2026 if this proposal is approved** | **817758** |

---

As of December 31, 2025, Ducommun had approximately 903,657 shares of common stock subject to outstanding awards (under the Current Plan, 2020 Plan and 2013 Plan) or available for future awards under the Current Plan, which represented approximately 6.0% of our common stock outstanding, alternatively referred to as the overhang percentage. The Amended and Restated 2024 Stock Plan, if approved, will provide for the issuance of 619,595 shares in addition to shares remaining under the Current Plan. The 619,595 additional shares of common stock would increase the overhang percentage by approximately 4.2% to approximately 10.2%. Between 2023 and 2025, Ducommun's three-year average burn rate was 1.98%. We expect the Amended and Restated 2024 Stock Plan to be sufficient to support Ducommun's equity-based compensation programs for approximately 2 years.

### **Why You Should Vote for the Amended and Restated and Restated 2024 Stock Plan** 
The Board of Directors recommends that our shareholders approve the Amended and Restated 2024 Stock Plan because it believes appropriate equity incentives are important to attract and retain the highest caliber of employees, to link incentive reward to Ducommun performance, to encourage employee and director ownership in our Company, and to align the interests of participants to those of our shareholders. The approval of the Amended and Restated 2024 Stock Plan will enable us to continue to provide such incentives.

#### **Promotion of Good Corporate Governance Practices** 
The Board of Directors believes the use of share-based incentive awards promotes best practices in corporate governance by aligning participants' interests with maximizing shareholder value. Specific features of the Amended and Restated 2024 Stock Plan that are consistent with good corporate governance practices include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;**1.** Options and stock appreciation rights may not be granted with exercise prices
 lower than the fair market value of the underlying shares on the grant date;

**2.** Ducommun will not, without shareholder approval, reduce the exercise price of a stock option
 or stock appreciation right and, at any time when the exercise price of a stock option or stock appreciation right is above
 the fair market value, the Company will not, without shareholder approval (except in the case of a change in control), cancel
 and re-grant or exchange such stock option or stock appreciation right for cash or a new award;

**3.** Dividends or dividend equivalents credited/payable in connection with an award that is not
 yet vested will be subject to the same restrictions and risk of forfeiture as the underlying award and will not be paid until
 the underlying award vests;

**4.** Awards under the plan, including any shares subject to an award, may be subject to any recovery,
 recoupment, clawback and/or other forfeiture policy maintained by Ducommun in the future;

**5.** No liberal share recycling;

**6.** Annual limit on equity and cash compensation that may be paid or awarded to non-employee directors;
 and

**7.** Limits on full-value awards that can be granted.

### **Amended and Restated 2024 Stock Plan Summary** 
The following is a description of the material features of the Amended and Restated 2024 Stock Plan. The complete text of the 2024 Stock Plan, as amended and restated, is attached hereto as Appendix B to this Proxy Statement. The following discussion is qualified in all respects by reference to Appendix B.

#### **Purpose and Eligibility** 
The purpose of the Amended and Restated 2024 Stock Plan is to enable Ducommun and its subsidiaries to attract, retain and motivate participants by providing for or increasing their proprietary interests in Ducommun. Any person who is a current or prospective employee or a non-employee director of Ducommun or any of its subsidiaries will be eligible to be considered for the grant of awards under the Amended and Restated 2024 Stock Plan. As of the December 31, 2025, approximately 7 non-employee directors, 5 executive officers and 70 other employees of Ducommun and its subsidiaries were so eligible.

#### **Shares Subject to the Amended and Restated 2024 Stock Plan and Awards** 
The maximum number of shares of common stock that may be issued pursuant to awards granted under the Amended and Restated 2024 Stock Plan is 1,364,972, subject to adjustments to prevent dilution, plus any shares of common stock subject to outstanding awards under the Current Plan as of March 2, 2026 that on or after March 2, 2026 are forfeited, terminated, expire or otherwise lapse without being exercised (to the extent applicable), or are settled in cash.

The Amended and Restated 2024 Stock Plan provides that the aggregate dollar value of equity-based awards (based on the grant date fair value of such awards) and cash compensation granted under the Amended and Restated 2024 Stock Plan or otherwise during any calendar year to any non-employee director shall not exceed $700,000; provided, however, that in the calendar year in which a non-employee director first joins the Board of Directors or is first designated as Chairman of the

[Back to Contents](#toc)

Board of Directors or Lead Director, the maximum aggregate dollar value of equity-based and cash compensation granted to the participant may be up to two hundred percent (200%) of the foregoing limit and any tandem stock appreciation rights shall not count against the foregoing limit.

Shares of common stock issued under the Amended and Restated 2024 Stock Plan may be either authorized and unissued shares or previously issued shares acquired by Ducommun. On forfeiture, termination or expiration of an unexercised or unvested award under the Amended and Restated 2024 Stock Plan, in whole or in part, the number of shares of common stock subject to such award again become available for grant under the Amended and Restated 2024 Stock Plan. The Amended and Restated 2024 Stock Plan provides that shares retained by or delivered to Ducommun to pay the exercise price or withholding taxes in connection with the exercise of an outstanding stock option, unissued shares resulting from the settlement of stock appreciation rights in stock, and shares purchased by Ducommun in the open market do not become available for issuance as future awards under the Amended and Restated 2024 Stock Plan.

The closing price of Ducommun's stock on March 2, 2026 was $130.28 per share.

#### **Administration** 
The Amended and Restated 2024 Stock Plan is administered by the Compensation Committee, which is a committee of two or more independent directors appointed by the Board of Directors of Ducommun (the **"Committee"**), or by the Board of Directors as a whole for issuances of awards to directors. The Committee has full and final authority to select the employees to receive awards and to grant such awards. Subject to the provisions of the Amended and Restated 2024 Stock Plan, the Committee has a wide degree of flexibility in determining the terms and conditions of awards and the number of shares to be issued pursuant thereto, including conditioning the receipt or vesting of awards upon achievement by Ducommun of specified performance criteria. The expenses of administering the Amended and Restated 2024 Stock Plan will be borne by Ducommun.

Subject to certain limitations, the Committee has the authority to delegate the administration of the Plan, and the Plan permits Ducommun's Board of Directors to exercise the Committee's powers, other than with respect to matters required by law to be determined by the Committee. In addition, the Committee has the authority to delegate to one or more officers of Ducommun the authority to perform any or all things that the Committee is authorized and empowered to do or perform under the Amended and Restated 2024 Stock Plan. To the extent such a delegation does occur, the resolution or policy so authorizing such officer or officers must specify the total number of awards (if any) such officer or officers may award pursuant to such delegated authority (which cannot exceed the annual allotment of shares of common stock approved by the Committee), and that any such award shall be subject to the form of award agreement approved by the Committee.

All decisions, determinations and interpretations by the Board of Directors and/or the Committee regarding the Amended and Restated 2024 Stock Plan, any rules and regulations under the Amended and Restated 2024 Stock Plan and the terms and conditions of or operation of any award granted under the Amended and Restated 2024 Stock Plan, will be final and binding on all participants, beneficiaries, heirs, assigns or other persons holding or claiming rights under the Amended and Restated 2024 Stock Plan or any award. The Board of Directors and/or the Committee will consider such factors as it deems relevant, in its sole and absolute discretion, to making such decisions, determinations and interpretations including, without limitation, the recommendations or advice of any officer or other employee of Ducommun and such attorneys, consultants and accountants as it may select.

#### **Awards** 
The Amended and Restated 2024 Stock Plan authorizes the Committee to enter into any type of arrangement with an eligible participant that, by its terms, involves or might involve the issuance of common stock or any other security or benefit with an exercise or conversion privilege at a price related to common stock or with a value derived from the value of common stock. Awards are not restricted to any specified form or structure and may include, without limitation, sales or bonuses of stock, Cash-LTIPs, restricted stock, restricted stock units, stock options, stock purchase warrants, other rights to acquire stock, securities convertible into or redeemable for stock, stock appreciation rights, phantom stock, dividend equivalents, performance units or performance shares, including revenue performance stock units. Any stock option granted to an employee may be a tax-benefited incentive stock option (an **"Incentive Stock Option"**) or a nonqualified stock option that is not tax-benefited (a **"Nonqualified Option"**). An award to a participant may consist of one such security or benefit or two or more of them in tandem or in the alternative. Common stock may be issued pursuant to awards under the Amended and Restated 2024 Stock Plan for any lawful consideration as determined by the Committee, including, without limitation, services rendered by a recipient of an award under the Amended and Restated 2024 Stock Plan.

A participant does not have voting rights with respect to any common stock subject to awards under the Amended and Restated 2024 Stock Plan until the participant has become the holder of record of the common stock. Dividends or dividend equivalents credited/payable in connection with an award under the Amended and Restated 2024 Stock Plan (to the extent such dividends or dividend equivalents may become credited/

payable for the award) that is not yet vested will be subject to the same restrictions and risk of forfeiture as the underlying award and will not be paid until the underlying award vests. Dividend equivalent rights will not be granted in connection with any award of stock options or stock appreciation rights under the Amended and Restated 2024 Stock Plan.

The exercise or base price for any stock option or stock appreciation right granted may not be less than the fair market value of the common stock subject to that award on the grant date. There is one exception to this requirement. This exception allows the exercise or base price per share with respect to an award that is granted in connection with a merger or other acquisition as a substitute or replacement award for awards held by employees or directors of the acquired entity to be less than 100% of the fair market value on the grant date if such exercise or base price is based on an adjustment method or formula set forth in the terms of the awards held by such individuals or in the terms of the agreement providing for such merger or other acquisition. The term of all stock options and stock appreciation rights granted under the Amended and Restated 2024 Stock Plan may not exceed 10 years.

#### **Vesting** 
Subject to the minimum vesting provisions described in this paragraph, the vesting of awards granted under the Amended and Restated 2024 Stock Plan will occur when and in such installments and/or pursuant to the achievement of such performance criteria, in each case, as the Committee, in its sole and absolute discretion, will determine.

The Committee may establish performance criteria and level of achievement versus such criteria that will determine the number of shares of common stock, units, or cash to be granted, retained, vested, issued or issuable under or in settlement of or the amount payable pursuant to an award under the Amended and Restated 2024 Stock Plan, which criteria may include any one or more of the following performance criteria, either individually, alternatively or in any combination, applied to either Ducommun as a whole or to a business unit or subsidiary, either individually, alternatively or in any combination, and measured either annually or cumulatively over a period of years, on an absolute basis or relative to a pre-established target, to previous years' results or to a designated comparison group, either based upon United States Generally Accepted Accounting Principles (**"GAAP"**) or non-GAAP financial results, in each case as specified by the Committee: earnings per share (diluted and/or basic), revenue, net profit after tax, gross profit, operating profit, earnings before interest, taxes, depreciation and amortization ("EBITDA"), earnings before interest and taxes ("EBIT"), cash flow (before or after dividends), free cash flow (or free cash flow per share), asset quality, stock price performance, unit volume, return on equity, change in working capital, change in indebtedness or financial leverage, return on capital or shareholder return, return on total capital, return on invested capital, return on investment, return on assets or net assets, market capitalization, economic value added, debt leverage (debt to capital), revenue, income or net income, operating income, operating profit or net operating profit, operating margin or profit margin, return on operating revenue, cash flow from operations, operating ratio, operating revenue, net service revenue and/or total backlog, days sales outstanding, health and safety or customer service.

The Board of Directors and/or Committee may, in an award agreement or otherwise, provide for the deferred delivery of common stock or cash upon settlement, vesting or other events with respect to restricted stock units. However, in no event will election to defer the delivery of common stock or any other payment with respect to any award be allowed if the Board of Directors and/or Committee determines, in its sole discretion that the deferral would result in the imposition of the additional tax under applicable law. Ducommun, the Board of Directors and/or the Committee will have no liability to an employee, or any other party, if an award that is intended to be exempt from, or compliant with, applicable tax law is not so exempt or compliant or for any action taken by the Board of Directors and/or the Committee.

#### **Acceleration** 
An award granted under the Amended and Restated 2024 Stock Plan may include a provision accelerating the receipt of benefits upon the occurrence of specified events, such as a change of control of Ducommun or a dissolution, liquidation, merger, reclassification, sale of substantially all of the property and assets of Ducommun or other significant corporate transaction whereby in the event of a change in control with qualifying termination of employment (x) stock options become fully exercisable immediately for the full term of the options, (y) performance stock units become vested immediately based on our actual achievement of performance measures for periods through the date of termination of employment and at the target number of shares for periods after the date of termination of employment, and (z) restricted stock units vest immediately.

#### **Duration of the Amended and Restated 2024 Stock Plan** 
Awards may not be granted under the Amended and Restated 2024 Stock Plan after the tenth anniversary of the adoption of the Amended and Restated 2024 Stock Plan. Although any award that was duly granted on or prior to such date may thereafter be exercised or settled in accordance with its terms, no shares of common stock may be issued pursuant to any award after the tenth anniversary of the adoption of the Amended and Restated 2024 Stock Plan.

#### **Transferability** 
Awards under the Amended and Restated 2024 Stock Plan may not be sold, transferred for value, pledged, assigned, or otherwise alienated or hypothecated by a participant other than by will or the laws of descent and distribution, and each stock option or stock appreciation right is exercisable only by the participant during his or her lifetime. Notwithstanding the foregoing, outstanding stock options may be exercised following the participant's death by the participant's beneficiaries or as permitted by the Board of Directors and/ or Committee, and, to the extent permitted by the Board of Directors and/or Committee, the person to whom an award is initially granted may make certain limited transfers to certain family members, family trusts or family partnerships.

#### **Amendment and Termination** 
Subject to limitations imposed by law, the Board of Directors of Ducommun may amend or terminate the Amended and Restated 2024 Stock Plan at any time and in any manner. However, no such amendment or termination may deprive the recipient of an award previously granted under the Amended and Restated 2024 Stock Plan of any rights thereunder without his or her consent. Notwithstanding the foregoing, no such amendment shall, without the approval of the shareholders of Ducommun:

&nbsp;&nbsp;&nbsp;&nbsp;**(a)** increase the maximum number of common stock for which awards may be granted under
 the Amended and Restated 2024 Stock Plan;

**(b)** reduce the price at which options may be granted below the price provided for in the Amended
 and Restated 2024 Stock Plan;

**(c)** reprice outstanding options or stock appreciation rights;

**(d)** extend the term of the Amended and Restated 2024 Stock Plan;

**(e)** change the class of persons eligible to be participants;

**(f)** increase the individual maximum limits set forth in the Amended and Restated 2024 Stock Plan;
 or

**(g)** otherwise amend the Amended and Restated 2024 Stock Plan in any manner requiring shareholder
 approval by law or the rules of any stock exchange or market or quotation system on which the common stock is traded, listed
 or quoted.

#### **Compensation Recoupment Policy** 
Subject to the terms and conditions of the Amended and Restated 2024 Stock Plan, the administrator may provide at the time an award is granted that any participant and/or any award, including any shares subject to an award, will be subject to any recovery, recoupment, clawback and/or other forfeiture policy maintained by Ducommun from time to time, including the Second Amended and Restated Clawback Policy.

#### **New Plan Benefits** 
The future awards, if any, that will be made to eligible persons under the Amended and Restated 2024 Stock Plan are subject to the discretion of the Administrator, and therefore, the benefits or number of shares subject to awards that may be granted in the future to our executive officers, employees and directors is not currently determinable. Therefore, a New Plan Benefits Table is not provided.

&nbsp;&nbsp;&nbsp;&nbsp;*(1)* *Consists of the 2024 Stock Plan. The number of securities to be issued consists of 105,784 for stock options, 273,409 for restricted stock units and 326,301 for performance stock units at target. The weighted average exercise price applies only to the stock options.* 

*(2)* *The 2018 Employee Stock Purchase Plan enables employees to purchase our common stock at a 15% discount to the lower of the market value at the beginning or end of each six-month offering period. As such, the number of shares that may be issued during a given six-month period and the purchase price of such shares cannot be determined in advance. See Note 11 to our consolidated financial statements included in Part IV, Item 15(a) of Ducommun's Annual Report on Form 10-K.* 

*(3)* *Awards are not restricted to any specified form or structure and may include, without limitation, sales or bonuses of stock, restricted stock, stock options, reload stock options, stock purchase warrants, other rights to acquire stock, securities convertible into or redeemable for stock, stock appreciation rights, limited stock appreciation rights, phantom stock, dividend equivalents, performance units or performance shares, and an award may consist of one such security or benefit, or two or more of them in tandem or in alternative.* 

#### **Federal Income Tax Treatment** 
The following is a brief description of the anticipated federal income tax treatment that generally will apply to awards granted under the Amended and Restated 2024 Stock Plan, based on federal income tax laws in effect on the date of this Proxy Statement. The exact federal income tax treatment of awards will depend on the specific circumstances of the grantee. No information is provided herein with respect to estate, inheritance, gift, state, or local tax laws, although there may be certain tax consequences upon the receipt or exercise of an award or the disposition of any acquired shares under those laws. Grantees are advised to consult their personal tax advisors with regard to all consequences arising from the grant or exercise of awards, and the disposition of any acquired shares.

#### **Incentive Stock Options** 
Pursuant to the Amended and Restated 2024 Stock Plan, employees may be granted options which are intended to qualify as Incentive Stock Options under the provisions of Section 422 of the Internal Revenue Code of 1986, as amended (the "**Code**"). Generally, the optionee is not taxed and Ducommun is not entitled to a deduction on the grant or the exercise of an Incentive Stock Option. If the optionee sells the shares acquired upon the exercise of an Incentive Stock Option ("**Incentive Stock Option Shares"**) at any time after the later of (a) one year after the date of transfer of shares to the optionee pursuant to the exercise of such Incentive Stock Option and (b) two years after the date of grant of such Incentive Stock Option (the "**Incentive Stock Option Holding Period**"), then the optionee will recognize capital gain or loss equal to the difference between the sales price and the exercise price paid for the Incentive Stock Option Shares, and Ducommun will not be entitled to any deduction.

However, if the optionee disposes of the Incentive Stock Option Shares at any time during the Incentive Stock Option Holding Period, then (1) the optionee will recognize capital gain in an amount equal to the excess, if any, of the sales price over the fair market value of the Incentive Stock Option Shares on the date of exercise, (2) the optionee will recognize ordinary income equal to the excess, if any, of the lesser of the sales price or the fair market value of the Incentive Stock Option Shares on the date of exercise, over the exercise price paid for the Incentive Stock Option Shares, (3) the optionee will recognize capital loss equal to the excess, if any, of the exercise price paid for the Incentive Stock Option Shares over the sales price of the Incentive Stock Option Shares, and (4) Ducommun will generally be entitled to a deduction in an amount equal to the amount of ordinary income recognized by the optionee.

[Back to Contents](#toc)

#### **Nonqualified Options** 
The grant of a Nonqualified Option is generally not a taxable event for the optionee. Upon exercise of the option, the optionee will generally recognize ordinary income in an amount equal to the excess of the fair market value of the stock acquired upon exercise of the Nonqualified Option ("**Nonqualified Option Shares**") over the exercise price of such option, and Ducommun will be entitled to a deduction equal to such amount. A subsequent sale of the Nonqualified Option Shares generally will give rise to capital gain or loss equal to the difference between the sales price and the sum of the exercise price paid for such shares plus the ordinary income recognized with respect to such shares.

#### **Stock Appreciation Rights** 
A grantee is not taxed on the grant of a stock appreciation right. On exercise, the grantee recognizes ordinary income equal to the cash or the fair market value of any shares received. We are entitled to an income tax deduction in the year of exercise in the amount recognized by the grantee as ordinary income.

#### **Restricted Stock, Restricted Stock Units, Performance Shares and Performance Units** 
Grantees of restricted stock, restricted stock units, performance shares and performance share units, including revenue performance stock units, and Cash LTIPs do not recognize income at the time of the grant. When the award vests (in the case of restricted stock and performance shares) or is paid (in the case of restricted stock units and performance share units), grantees generally recognize ordinary income in an amount equal to the fair market value of the stock or units at such time, and we will receive a corresponding deduction. Where a valid Section 83(b) election is made by the participant and in the event the participant forfeits the shares to us (e.g., upon the participant's termination of employment prior to vesting), the participant may not claim a deduction with respect to the income recognized as a result of the election. Dividends paid with respect to unvested shares of restricted shares generally will be taxable as ordinary income to the participant at the time the dividends are received.

#### **Miscellaneous Tax Issues** 
For awards granted under the Amended and Restated 2024 Stock Plan that do not fall clearly into the categories described above, the federal income tax treatment will depend upon the specific terms of such awards. Generally, Ducommun will be required to make arrangements for withholding applicable taxes with respect to any ordinary income recognized by a participant in connection with awards made under the Amended and Restated 2024 Stock Plan.

Special rules will apply in cases where an optionee pays the exercise or purchase price of the option or applicable withholding tax obligations under the Amended and Restated 2024 Stock Plan by delivering previously owned common stock or by reducing the amount of common stock otherwise issuable pursuant to the option. The surrender or withholding of such shares will in certain circumstances result in the recognition of income with respect to such shares.

The Amended and Restated 2024 Stock Plan provides that, in the event of certain changes in ownership or control of the Corporation, the right to exercise options otherwise subject to a vesting schedule may be accelerated. In the event such acceleration occurs and depending upon the individual circumstances of the recipient, certain amounts with respect to such options may constitute "excess parachute payments" under the "golden parachute" provisions of the Code. Pursuant to these provisions, a recipient will be subject to a 20% excise tax on any "excess parachute payments" and Ducommun will be denied any deduction with respect to such payment. Optionees should consult their tax advisors as to whether accelerated vesting of an option in connection with a change in ownership or control of Ducommun would give rise to an excess parachute payment.

As described above, Section 162(m) denies a deduction to any publicly held corporation for compensation paid to certain employees in a taxable year to the extent that compensation exceeds $1,000,000 for a covered employee. It is possible that compensation attributable to awards under the plan, either on their own or when combined with all other types of compensation received by a covered employee from Ducommun, may cause this limitation to be exceeded in any particular year.

The affirmative vote of a majority of the shares of the Corporation's common stock represented in person or by proxy and entitled to vote at a duly held shareholder's meeting is required for the approval of the Amended and Restated 2024 Stock Plan.

**How can I vote my shares?**

If you are a shareholder of record, there are several ways for you to vote your shares or submit your proxy:

&nbsp;&nbsp;&nbsp;&nbsp;**(1)** By Telephone—Call (800) 690-6903 prior to the day of the Annual Meeting and follow
 the instructions on your Notice or proxy card;

**(2)** By Internet—Before the Annual Meeting by visiting www. proxyvote.com and following the instructions
 on your Notice or proxy card; During the Annual Meeting by visiting www.virtualshareholdermeeting.com/DCO2026; or

**(3)** By Mail—If you received your proxy materials by mail, you can sign, date and return the enclosed
 proxy card.

If your shares are held in the name of a bank, broker or other nominee, your bank, broker or other nominee will tell you how to vote your shares. If you wish to personally vote your shares at the Annual Meeting, you must obtain a legal proxy from your broker or nominee giving you the right to vote the shares.

**What does it mean to vote by proxy?**

**How many votes am I entitled to?**

In the election of the Class of 2029 directors, holders of common stock have cumulative voting rights, which means you are entitled to a number of votes equal to the number of directors to be elected multiplied by the number of shares you hold on the Record Date. You can cast all of your votes for one candidate or distribute your votes between three candidates. You cannot cast votes for more than three candidates. On all other matters to come before the Annual Meeting, each holder of common stock will be entitled to one vote for each share owned.

If you submit a proxy without indicating your instructions, your shares will be voted as follows: (1) "FOR" the election of two directors named in the Proxy Statement to serve until Ducommun's 2029 Annual Meeting of Shareholders, (2) "FOR" approval of Ducommun's executive compensation on an advisory basis, and (3) "FOR" the ratification of the selection of PricewaterhouseCoopers LLP as Ducommun's independent registered public accounting firm for the year ending December 31, 2026, (4) "FOR" approval of an amendment and restatement of the Company's 2024 Stock Incentive Plan and (5) in the proxy holder's discretion on such other business as may properly come before the Annual Meeting or any adjournment thereof.

**What if I change my mind after I give my proxy?**

You may revoke your proxy at any time before the taking of the vote at the Annual Meeting by (1) sending a written revocation to the Corporate Secretary at the address shown above, (2) submitting a later dated valid proxy, or (3) participating in and voting at the virtual Annual Meeting (although participating in the virtual Annual Meeting will not in and of itself revoke a proxy).

**Who will count the votes?**

Mr. Richard Leza with the Carideo Group will count the votes and act as the inspector of election at the Annual Meeting.

**What is the quorum requirement for the meeting?**

In order to conduct business at the Annual Meeting, we must have a "quorum"—meaning that a majority in voting power of the outstanding shares of common stock entitled to vote must be present, either in person or by proxy. Shares of common stock that reflect abstentions and broker non-votes (described in the response to the next question) will be treated as present and entitled to vote for the purposes of establishing a quorum.

**What if I own my shares through a bank or broker and don't give voting instructions?**

Without your specific voting instructions, your bank or broker will not be allowed to vote your shares at the Annual Meeting on non-routine matters. The determination of whether a proposal is "routine" or "non-routine" will be made by the NYSE or by Broadridge Financial Solutions, Inc. our independent agent to receive and tabulate shareholder votes, based on NYSE rules that regulate member brokerage firms. If a proposal is deemed "routine" and you do not give instructions to your broker or nominee, they may, but are not required to, vote your shares with respect to the proposal. If the proposal is deemed "non-routine" and you do not give instructions to your broker or nominee, they may not vote your shares with respect to the proposal and the shares will be treated as broker non-votes. Shares that constitute broker non-votes with respect to a particular proposal will not have any effect on the outcome of that proposal. Because your bank or broker does not have discretion to vote without your instructions on non-routine matters, we strongly encourage you to provide your voting instructions so your shares will be counted.

Your broker, bank or other nominee is not permitted to vote on your behalf in the election of directors (Proposal 1), the advisory vote on executive compensation (Proposal 2) or approval of an amendment and restatement of the Company's 2024 Stock Incentive Plan (Proposal 4), unless you provide specific instructions to them. Accordingly, if you do not provide timely voting instructions to your broker, bank or other nominee that holds your shares, that institution will be prohibited from voting on all of the proposals in its discretion, except the ratification of the appointment of the independent registered public accounting firm (Proposal 3).

**Where can I find the voting results of the Annual Meeting?**

We intend to announce preliminary voting results at the Annual Meeting and publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

**Who is paying for this solicitation?**

We intend to solicit proxies by mail, telephone, facsimile, and internet. D. F. King & Co., Inc. has been retained to assist in the solicitation of proxies, for which it will be paid a fee of approximately $8,500 plus reimbursement of out-of-pocket expenses. Brokers, nominees, banks, and other custodians will be reimbursed for their costs incurred in forwarding solicitation material to beneficial owners. All expenses incident to the proxy solicitation will be paid by Ducommun.

**I live with another shareholder. Why did we only receive one copy of the proxy materials?**

To reduce the expense of delivering duplicate proxy materials to multiple shareholders at the same address, we have adopted a procedure approved by the SEC called "householding." Under this procedure, certain shareholders of record who have the same address and last name, and who do not participate in electronic delivery of proxy materials, will receive only one copy of our Notice of Internet Availability of Proxy Materials and, as applicable, any additional proxy materials that are delivered until such time as one or more of these shareholders notify us that they want to receive separate copies. Householding reduces duplicate mailings and saves printing costs and postage fees, as well as natural resources. Shareholders who participate in householding will continue to give proxy voting instructions for their individual shares.

If you receive a single set of proxy materials as a result of householding, and you would like to have separate copies of our Notice of Internet Availability of Proxy Materials, Annual Report, or Proxy Statement mailed to you in the future, please submit a request in writing or by telephone to our Corporate Secretary at the address or phone number shown above, and we will promptly send you the materials you request. However, if you want to receive a paper proxy card or voting instruction

card or other proxy materials for the purposes of this year's Annual Meeting, you will need to follow the instructions included in the Notice of Internet Availability that you received. You can also contact our Corporate Secretary if you received multiple copies of the Annual Meeting materials and would prefer to receive a single copy in the future.

**How can I nominate a candidate for election, or submit a shareholder proposal, for consideration at the 2026 Annual Meeting?**

From time to time our individual shareholders submit proposals that they believe should be voted upon by the shareholders. The SEC has adopted regulations that govern the inclusion of such proposals in our annual proxy materials. All such written proposals must be received by our Corporate Secretary at the address shown above no later than November 13, 2026, and must comply with the SEC regulations in order to be considered for inclusion in Ducommun's 2026 proxy materials.

In addition, a shareholder who intends to solicit proxies in support of nominees submitted under the advance notice provisions of our Bylaws must provide the notice required under Rule 14a-19 to the Corporate Secretary not later than February 28, 2027. The notice requirement under Rule 14a-19 is in addition to the applicable advance notice requirements under our Bylaws, which require that nominations for directors and other proposals not intended to be included in the Company's proxy materials must be received by our Corporate Secretary not later than the close of business on the ninetieth (90<sup>th</sup>) day nor earlier than the close of business on the one hundred twentieth (120<sup>th</sup>) day prior to the first anniversary of the preceding year's annual meeting (provided, however, that in the event that the date of the annual meeting is more than thirty five (35) days before or more than seventy (70) days after such anniversary date, notice by the shareholder must be so delivered not earlier than the close of business on the one hundred twentieth (120<sup>th</sup>) day prior to the date of such annual meeting and not later than the close of business on the later of the ninetieth (90<sup>th</sup>) day prior to the date of such annual meeting. However, if the first public announcement of the date of such advanced or delayed annual meeting is less than one hundred (100) days prior to the date of such annual meeting, notice of any shareholder proposal will be timely if received no later than the close of business on the 10<sup>th</sup> day following the day on which notice of the date of the annual meeting was mailed or public disclosure of such date was made.

## **Appendix A** 

### **Reconciliation of GAAP and Non-GAAP Financial Measures** 
This Proxy Statement includes the following financial measures defined as non-GAAP financial measures by the SEC: Adjusted EBITDA, Adjusted EBITDA as a percentage of Revenue and backlog. The tables below reconcile the non-GAAP financial measures to the most directly comparable financial measures prepared in accordance with Generally Accepted Accounting Principles ("GAAP").

Ducommun 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. Ducommun'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 included in this Proxy Statement calculated in accordance with GAAP. Ducommun discloses different non-GAAP financial measures in order to provide greater transparency and to help Ducommun's investors to more meaningfully evaluate and compare Ducommun's results to its previously reported results. The non-GAAP financial measures that Ducommun uses may not be comparable to similarly titled financial measures used by other companies.

### **Reconciliation of GAAP to Non-GAAP Net (Loss) Income to Adjusted EBITDA** 
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 and Adjusted EBITDA as a percentage of Revenue provide additional useful information to clarify and enhance the understanding of the factors and trends affecting our past performance and future prospects. We define Adjusted EBITDA, explain how it is calculated, and provide a reconciliation to the most comparable GAAP measure in the table below. Adjusted EBITDA and the related financial ratios 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 (loss) income or any other performance measures derived in accordance with GAAP, or as an alternative to net cash (used in) 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 non-GAAP operating performance measures internally as complementary financial measures to evaluate the performance and trends of our businesses. We also 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 substitutes for analysis of our results as reported under GAAP. Some of these limitations include:

&nbsp;&nbsp;&nbsp;&nbsp;• 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 or charges resulting from matters unrelated to our ongoing
 operations; and

• Other companies in our industry may calculate Adjusted EBITDA differently from us, limiting their
 usefulness as comparative measures.

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 consolidated financial statements contained on Form 10-K filed with the SEC.

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

&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;• 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 (loss) income when calculating Adjusted EBITDA:

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

• Income tax (benefit) 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;

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

• 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;

• Gain on sale-leaseback 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 performance;

• Success bonus related to completion of sale-leaseback transaction may be useful to our investors
 in evaluating our core operating performance;

• 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;

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

• Litigation settlement and related costs, net, 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;

• Loss on extinguishment of debt may be useful to our investors for determining current cash flow;

• Other debt refinancing costs may be useful to our investors in evaluating our core operating performance;

• Gain on sale of property and other assets may be useful to our investors in evaluating our core performance;
 and

• Gain on divestitures may be useful to our investors for determining current cash flows.

### **Reconciliation of GAAP to Non-GAAP – Backlog** 
Performance obligations are defined as customer placed purchase orders with firm fixed price and firm delivery dates. We define 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 in this Proxy Statement 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 our control. Backlog is affected by timing differences in the placement of customer orders and tends to be concentrated in some of our programs.

## **Appendix B** 

### **Amended and Restated Ducommun Incorporated 2024 Stock Incentive Plan** 

#### **Section 1. &nbsp;&nbsp;&nbsp;&nbsp; Purpose of Plan** 
The purpose of the Amended and Restated 2024 Stock Incentive Plan (the "Plan") of Ducommun Incorporated, a Delaware corporation (the "Company"), is to enable the Company and its subsidiaries to attract, retain and motivate their employees and nonemployee directors by providing for or increasing the proprietary interests of such persons in the Company.

#### **Section 2. &nbsp;&nbsp;&nbsp;&nbsp; Persons Eligible Under Plan** 
Any person who is a current or prospective employee or a nonemployee director of the Company or any of its subsidiaries (a "Participant") shall be eligible to be considered for the grant of Awards (as hereinafter defined) hereunder.

#### **Section 3. &nbsp;&nbsp;&nbsp;&nbsp; Awards** 
&nbsp;&nbsp;&nbsp;&nbsp;(a) The Board of Directors and/or the Committee (as hereinafter defined), on behalf of the Company, is
 authorized under this Plan to enter into any type of arrangement with a Participant that is not inconsistent with the provisions
 of this Plan and that, by its terms, involves or might involve the issuance of (i) shares of common stock, par value $.01 per share,
 of the Company ("Common Shares") or (ii) a Derivative Security (as such term is defined in Rule 16a-1 promulgated under
 the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as such Rule may be amended from time to time)
 with an exercise or conversion privilege at a price related to the Common Shares or with a value derived from the value of the Common
 Shares. The entering into of any such arrangement is referred to herein as the "grant" of an "Award."

(b) Awards are not restricted to any specified form or structure and may include, without limitation,
 sales or bonuses of stock, restricted stock, restricted stock units, stock options, stock purchase warrants, other rights to acquire
 stock, securities convertible into or redeemable for stock, stock appreciation rights, phantom stock, dividend equivalents, performance
 units or performance shares, and Cash LTIPs, and an Award may consist of one such security or benefit, or two or more of them in
 tandem or in the alternative; provided that, Participants shall have no voting rights with respect to any Common Shares subject to
 such Awards until the Participant has become the holder of record of the Common Shares; provided, further, that dividends or dividend
 equivalents credited/payable in connection with an Award (to the extent such dividends or dividend equivalents may become credited/payable
 for the Award) that are not yet vested shall be subject to the same restrictions and risk of forfeiture as the underlying Award and
 shall not be paid until the underlying Award vests. Dividend equivalent rights shall not be granted in connection with any Award
 of stock options or stock appreciation rights.

(c) Common Shares may be issued pursuant to an Award for any lawful consideration as determined by the Board of Directors and/or
 the Committee, including, without limitation, services rendered by the recipient of such Award.

(d) Subject to the provisions of this Plan, the Board of Directors and/or the Committee, in its sole and absolute discretion, shall
 determine all of the terms and conditions of each Award granted under this Plan, which terms and conditions may include, among other
 things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) a provision permitting the recipient of such Award, including any recipient who is a director or
 officer of the Company, to pay the purchase price of the Common Shares or other property issuable pursuant to such Award, or such
 recipient's tax withholding obligation with respect to such issuance, in whole or in part, by any one or more of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) the delivery of previously owned shares of capital stock of the Company (including "pyramiding")
 or other property, provided that the Company is not then prohibited from purchasing or acquiring shares of its capital stock or such
 other property,

(B) a reduction in the amount of Common Shares or other property otherwise issuable pursuant to such
 Award,

(C) an irrevocable commitment by a broker to pay over such amount from a sale of the shares issuable
 pursuant to such Award, or

(D) the delivery of a promissory note, the terms and conditions of which shall be determined by the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Subject to Section 4 hereof, a provision conditioning or accelerating the receipt of
 benefits pursuant to such Award upon the occurrence of specified events, including, without limitation, an event of the type described
 in Section 8 hereof; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) a provision required in order for such Award to qualify as an incentive stock option
 ("Incentive Stock Option") under Section 422 of the Internal Revenue Code of 1986, as amended, and the regulations and
 guidance promulgated thereunder (the "Code"), provided that the recipient of such Award is eligible under the Code to
 receive an Incentive Stock Option.

&nbsp;&nbsp;&nbsp;&nbsp;(e) Notwithstanding anything herein to the contrary, with respect to stock options and
 stock appreciation rights issued under the Plan, the Board of Directors and/or the Committee, in its sole and absolute discretion,
 shall determine the exercise or base price per Common Share subject to such Awards, which, in no event will be less than the Fair
 Market Value (as defined below) of the Common Shares on the date of grant; provided, however, that the exercise or base price per
 Common Share with respect to a stock option or stock appreciation right that is granted in connection with a merger or other acquisition
 as a substitute or replacement award for options and/or stock appreciation rights held by employees or directors of the acquired
 entity may be less than 100% of the Fair Market Value of the Common Shares on the date such Award is granted if such exercise or
 base price is based on an adjustment method or formula set forth in the terms of the awards held by such individuals or in the terms
 of the agreement providing for such merger or other acquisition. For purposes of the Plan, the term "Fair Market Value"
 means, as of any given date, the closing sales price on such date (or, if there are no reported sales on such date, on the last date
 prior to such date on which there were sales) of the Common Shares on the New York Stock Exchange Composite Tape.

(f) The Board of Directors and/or the Committee, in its sole and absolute discretion, shall determine
 the term of each stock option and stock appreciation right awarded under the Plan, which in no case shall exceed a period of ten
 (10) years from the date of grant.

(g) Other than in connection with a change in the Company's capitalization (as described in Section
 8), at any time when the exercise or base price of a stock option or stock appreciation right is above the Fair Market Value of a
 Common Share, the Company shall not, without shareholder approval (i) reduce the exercise or base price of such stock option or stock
 appreciation right, (ii) exchange such stock option or stock appreciation right for cash, another Award, or a new stock option or stock
 appreciation right with a lower exercise or base price or (iii) otherwise reprice such stock option or stock appreciation right.

(h) Notwithstanding anything herein to the contrary, and subject to Section 4, the grant, issuance, retention,
 vesting and/or settlement of restricted stock, restricted stock unit, performance share, performance unit and other similar Awards
 will occur when and in such installments and/or pursuant to the achievement of such performance criteria, in each case, as the Board
 of Directors and/or the Committee, in its sole and absolute discretion, shall determine provided, that Awards granted under the Plan
 may not become exercisable, vest or be settled, in whole or in part, prior to the one-year anniversary of the date of grant, except
 that the Board of Directors and/or the Committee may, subject to Section 4, provide that Awards become exercisable, vest or settle
 prior to such date in the event of the Participant's death or Disability. Notwithstanding the foregoing, up to 5% of the aggregate
 number of Common Shares authorized for issuance under this Plan (as described in Section 5 hereof) may be issued pursuant to Awards
 subject to any, or no, vesting conditions, as the Board of Directors and/or the Committee determines appropriate.

(i) The Committee may establish performance criteria and level of achievement versus such criteria that
 shall determine the number of Common Shares, units, or cash to be granted, retained, vested, issued or issuable under or in settlement
 of or the amount payable pursuant to an Award, which criteria may include any one or more of the following performance criteria,
 either individually, alternatively or in any combination, applied to either the Corporation as a whole or to a business unit or subsidiary,
 either individually, alternatively or in any combination, and measured either annually or cumulatively over a period of years, on
 an absolute basis or relative to a pre-established target, to previous years' results or to a designated comparison group,
 either based upon United States Generally Accepted Accounting Principles ("GAAP") or non-GAAP financial results, in each
 case as specified by the Committee: earnings per share (diluted and/or basic), revenue, net profit after tax, gross profit, operating
 profit, earnings before interest, taxes, depreciation and amortization ("EBITDA"), earnings before interest and taxes
 ("EBIT"), cash flow (before or after dividends), free cash flow (or free cash flow per share), asset quality, stock price
 performance, unit volume, return on equity, change in working capital, change in indebtedness or financial leverage, return on capital
 or shareholder return, return on total capital, return on invested capital, return on investment, return on assets or net assets,
 market capitalization, economic value added, debt leverage (debt to capital), revenue, income or net income, operating income, operating
 profit or net operating profit, operating margin or profit margin, return on operating revenue, cash from operations, operating ratio,
 operating revenue, net service revenue and/or total backlog, days sales outstanding, health and safety or customer service.

(j) The Board of Directors and/or Committee may, in an Award agreement or otherwise, provide for the
 deferred delivery of Common Shares or cash upon settlement, vesting or other events with respect to restricted stock units and performance
 stock units. Notwithstanding anything herein to the contrary, in no event will election to defer the delivery of Common Shares or
 any other payment with respect to any Award be allowed if the Board of Directors and/or Committee determines, in its sole discretion,
 that the deferral would result in the imposition of the additional tax under Section 409A(a)(1)(B) of the Code. The Company, the
 Board of Directors and/or the Committee shall have no liability to a Participant, or any other party, if an Award that is intended
 to be exempt from, or compliant with, Section 409A of the Code is not so exempt or compliant or for any action taken by the Board
 of Directors and/or the Committee.

#### **Section 4. &nbsp;&nbsp;&nbsp;&nbsp; Change in Control** 
&nbsp;&nbsp;&nbsp;&nbsp;(a) For purposes of the Plan, a "Change in Control" shall be deemed to have occurred
 if (i) a tender offer shall be made and consummated for the ownership of 30% or more of the outstanding voting securities of the
 Company (other than a tender offer by the Company), (ii) the Company shall be merged or consolidated with another corporation, and
 as a result of such merger or consolidation, less than 50% of the outstanding voting securities of the surviving or resulting corporation
 shall be owned in the aggregate by the former shareholders of the Company, other than affiliates (within the meaning of the Exchange
 Act) of any party to such merger or consolidation, as the same shall have existed immediately prior to such merger or consolidation,
 (iii) the Company shall sell, lease, exchange or transfer substantially all of its assets to another corporation, entity or
 person which is not a wholly-owned subsidiary, (iv) a person, as defined in Section 13(d) and 14(d) (as in effect on the
 date hereof) of the Exchange Act, shall acquire at any time 50% or more, or shall acquire within an 12-month period 30% or more,
 of the outstanding voting securities of the Company (whether directly, indirectly, beneficially or of record), (v) the shareholders
 of the Company approve and there shall be consummated a plan or proposal for the liquidation or dissolution of the Company, or (vi)
 during any period of twelve (12) consecutive months, individuals who, at the beginning of such period constitute the Board of Directors,
 cease for any reason to constitute at least a majority thereof unless the election, or the nomination for election by the Company's
 shareholders, of each new director was approved by a vote of at least two-thirds of the directors then still in office who were directors
 at the beginning of the period. For purposes hereof, ownership of voting securities shall take into account and shall include ownership
 as determined by applying the provisions of Rule 13d-3 (as in effect on the date hereof) under the Exchange Act. A sale or change
 in control of any other subsidiary of the Company by which the Participant is employed shall not be deemed a Change in Control of
 the Company for purposes of this Plan. Notwithstanding anything herein to the contrary, a Change in Control will only be deemed to
 have occurred if such transaction qualifies as a "change in control" of the Company within the meaning of Section 409A
 of the Code.

(b) In the event of a Change in Control in which the surviving corporation or acquiring corporation (or
 its parent company) does not assume or continue outstanding Awards under the Plan or substitute similar Awards for such outstanding
 Awards, then with respect to Awards that have not been assumed, continued or substituted and that are held by Participants who have
 not incurred a termination of employment prior to the effective date of the Change in Control, the following treatment shall apply
 to each Participant's Awards, as applicable, unless otherwise provided in the instrument evidencing the Award or any other
 written agreement between the Company, its subsidiaries or its affiliates and the Participant:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in the case of an option or stock appreciation right, the time
 when such Award may be exercised will be accelerated to a date prior to the effective date of the Change in Control (contingent upon
 the consummation of the Change in Control) as the Company determines (or, if the Company does not determine such a date, to the date
 that is five days prior to the effective date of the Change in Control) and such Awards will terminate if not exercised at or prior
 to the effective date of the Change in Control, and any repurchase rights held by the Company with respect to such Awards will lapse
 (contingent upon the consummation of the Change in Control);

(ii) in the case of any such Award the vesting of which is in whole or in part
 subject to performance-based vesting criteria, all conditions to the grant, issuance, retention, vesting or transferability of, or
 any other restrictions applicable to, such Award shall immediately lapse, and such Award shall immediately vest and the Participant
 shall have the right to receive a payment based on (x) the Company's actual achievement with respect to such performance-based
 vesting criteria for all periods through the effective date of the Change in Control (as determined by the Company), and (y) the
 target number of shares or other payments for periods after the effective date of the Change in Control, and any repurchase rights
 with respect to such Awards will lapse (contingent upon the effectiveness of the Change in Control); and

(iii) in the case of restricted stock and/or restricted stock units (other than
 those references in clause (ii) hereof), all conditions to the grant, issuance, retention, vesting or transferability of, or any
 other restrictions applicable to, such Award shall immediately lapse, such Awards shall immediately vest, and any repurchase rights
 with respect to such Awards will lapse (contingent upon the effectiveness of the Change in Control).

#### **Section 5. &nbsp;&nbsp;&nbsp;&nbsp; Stock Subject to Plan** 
&nbsp;&nbsp;&nbsp;&nbsp;(a) The aggregate number of Common Shares issued and issuable pursuant to all Awards granted
 under this Plan shall be 1,325,089 subject to adjustment as provided in Section 8 hereof, plus any Common Stock Shares that remained
 available for grant under the Ducommun Incorporated 2024 Stock Incentive Plan (the "Prior Plan"), as of April 29, 2026.

(b) For purposes of Section 5(a) hereof, the aggregate number of Common Shares issued under this Plan
 at any time shall equal only the number of Common Shares actually issued upon exercise or settlement of an Award. Notwithstanding
 the foregoing, Common Shares subject to an Award under the Plan may not again be made available for issuance under the Plan if such
 Common Shares are: (i) Common Shares

|  | that were subject to a stock-settled stock appreciation right and were not issued upon the net settlement or net exercise of such stock appreciation right, (ii) Common Shares used to pay the exercise or purchase price of a stock option or other Award, (iii) Common Shares delivered to or withheld by the Company to pay the withholding taxes related a stock option or stock appreciation right or the vesting or settlement of other Awards, or (iv) Common Shares repurchased on the open market with the proceeds of a stock option exercise. Common Shares subject to Awards that have been canceled, expired, forfeited or otherwise not issued under an Award and Common Shares subject to Awards settled in cash shall not count as Common Shares issued under this Plan. |
| (c) | The aggregate number of shares of Common Shares that may be issued pursuant to the exercise of Incentive Stock Options granted under this Plan shall not exceed the number set forth in Section 5(a), which number shall be calculated and adjusted pursuant to Section 8 only to the extent that such calculation or adjustment will not affect the status of any option intended to qualify as an Incentive Stock Option under Section 422 of the Code. |
| (d) | The aggregate dollar value of equity-based Awards (based on the grant date fair value of such Awards) and cash compensation granted under this Plan or otherwise during any calendar year to any one non-employee director shall not exceed $700,000; provided, however, that in the calendar year in which a non-employee director first joins the Board of Directors or is first designated as Chairman of the Board of Directors or Lead Directors, the maximum aggregate dollar value of equity-based and cash compensation granted to the Participant may be up to two hundred percent (200%) of the foregoing limit and the foregoing limit shall not count any tandem stock appreciation rights. |
| (e) | Awards may be granted and Common Shares may be issued by the Company in assumption of, or in substitution or exchange for, awards previously granted, or the right or obligation to make future awards, by a company acquired by the Company or any subsidiary or with which the Company or any subsidiary combines ("Substitute Awards"). Such Awards shall not reduce the Common Shares authorized for issuance under this Plan or authorized for grant under this Plan to a Participant in any calendar year. Additionally, in the event that a company acquired by the Company or any subsidiary, or with which the Company or any subsidiary combines, has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under this Plan, with such Awards reducing the number of shares available for grant under such pre-existing plan, and with no reduction of Common Shares authorized for issuance under this Plan; provided that Awards using such available shares under the existing Plan shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were employees or directors of such acquired or combined company before such acquisition or combination. |

---

#### **Section 6 . &nbsp;&nbsp;&nbsp;&nbsp; Duration of Plan** 
Awards shall not be granted under this Plan, as amended and restated, after April 29, 2036. Although Common Shares may be issued after April 29, 2036 pursuant to Awards granted prior to such date, no Common Shares shall be issued under this Plan after April 29, 2046.

#### **Section 7. &nbsp;&nbsp;&nbsp;&nbsp; Administration of Plan** 
&nbsp;&nbsp;&nbsp;&nbsp;(a) This Plan shall be administered by the Compensation Committee of the Board of Directors
 of the Company (the "Committee"), or, in the absence of a Committee, the Board of Directors itself. Any power of the
 Committee may also be exercised by the Board of Directors, except to the extent that the grant or exercise of such authority would
 cause any Award or transaction to become subject to (or lose an exemption under) the short-swing profit recovery provisions of Section
 16 of the Securities Exchange Act of 1934 or cause an Award otherwise intended to qualify as performance-based compensation under
 Section 162(m) of the Code not to qualify for such treatment. To the extent that any permitted action taken by the Board of Directors
 conflicts with action taken by the Committee, the Board of Directors' action shall control. The Committee may by resolution
 or written policy authorize one or more officers of the Company to perform any or all things that the Committee is authorized and
 empowered to do or perform under the Plan, and for all purposes under this Plan, such officer or officers shall be treated as the
 Committee; provided, however, that the resolution or policy so authorizing such officer or officers shall specify that the total
 number of Awards (if any) such officer or officers may award pursuant to such delegated authority shall not exceed the annual allotment
 of shares approved by the Committee, and any such Award shall be subject to the form of award agreement theretofore approved by the
 Committee. No such officer shall designate himself or herself as a recipient of any Awards granted under authority delegated to such
 officer. In addition, the Committee may delegate any or all aspects of the day-to-day administration of the Plan to one or more officers
 or employees of the Company or any subsidiary, and/or to one or more agents.

&nbsp;&nbsp;&nbsp;&nbsp;(b) Subject to the provisions of this Plan, the Board of Directors and/or the Committee shall
 be authorized and empowered to do all things necessary or desirable in connection with the administration of this Plan, including,
 without limitation, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) adopt, amend and rescind rules and regulations relating to this Plan;

(ii) determine which persons are Participants and to which of such Participants if any, Awards shall be
 granted hereunder;

(iii) to establish and verify the extent of satisfaction of any performance goals or other conditions applicable
 to the grant, issuance, exercisability, vesting and/or ability to retain any Award;

 this Plan (which need not be identical) and the terms of or form of any document or notice required to be delivered to the Company
 by Participants under this Plan;

(v) grant Awards to Participants and determine the terms and conditions thereof, including the number
 of Common Shares issuable pursuant thereto;

(vi) determine the extent to which adjustments are required pursuant to Section 8 hereof;

(viii) to make all other determinations deemed necessary or advisable for the administration of this Plan;
 and

(ix) to interpret and construe this Plan and the terms and conditions of all Awards granted hereunder
 and to make exceptions to any such provisions if the Board of Directors and/or the Committee, in good faith, determine that it is
 necessary to do so in light of extraordinary circumstances and for the benefit of the Company and so as to avoid unanticipated consequences
 or address unanticipated events (including any temporary closure of an applicable stock exchange, disruption of communications or
 natural catastrophe.

&nbsp;&nbsp;&nbsp;&nbsp;(c) All decisions, determinations and interpretations by the Board of Directors and/or the
 Committee regarding the Plan, any rules and regulations under the Plan and the terms and conditions of or operation of any Award
 granted hereunder, shall be final and binding on all Participants, beneficiaries, heirs, assigns or other persons holding or claiming
 rights under the Plan or any Award. The Board of Directors and/or the Committee shall consider such factors as it deems relevant,
 in its sole and absolute discretion, to making such decisions, determinations and interpretations including, without limitation,
 the recommendations or advice of any officer or other employee of the Company and such attorneys, consultants and accountants as
 it may select.

#### **Section 8. &nbsp;&nbsp;&nbsp;&nbsp; Adjustments** 
If the outstanding securities of the class then subject to this Plan are increased, decreased or exchanged for or converted into cash, property or a different number or kind of securities, or if cash, property or securities are distributed in respect of such outstanding securities, in either case as a result of a reorganization, merger, consolidation, recapitalization, restructuring, reclassification, dividend (other than a regular, quarterly cash dividend) or other distribution, stock split, reverse stock split or the like, or if substantially all of the property and assets of the Company are sold, then, unless the terms of such transaction shall provide otherwise, the Board of Directors and/or the Committee shall make appropriate and proportionate adjustments in (a) the number and type of, and exercise price for, shares or other securities or cash or other property that may be acquired pursuant to Incentive Stock Options and other Awards theretofore granted under this Plan, (b) the maximum number and type of shares or other securities that may be issued pursuant to Incentive Stock Options and other Awards thereafter granted under this Plan, and (c) the number and type of shares or other securities subject to the individual limits set forth in Section 5 of this Plan. To the extent any Award is subject to the achievement of one or more performance, financial or operating metric, the Committee shall have the authority to adjust such metric in its discretion to reflect the operating performance of the Company, including without limitation, adjustments to reflect the impact of changes in accounting, acquisitions and divestitures, asset impairments, debt transactions, restructurings, and other unusual, infrequent or nonrecurring events. Any such adjustments shall be made in accordance with and subject to the terms and conditions set forth in the applicable Award agreement, which may provide specific adjustments applicable to the metric for such Award. In no event shall any action be taken pursuant to this Section 8 that would change the payment or settlement date of an Award in a manner that would result in the imposition of any additional taxes or penalties pursuant to Section 409A of the Code. No right to purchase fractional shares shall result from any adjustment in Awards pursuant to this Section 8. In case of any such adjustment, the Common Shares subject to the Award shall be rounded down to the nearest whole share. The Company shall notify Participants holding Awards subject to any adjustments pursuant to this Section 8 of such adjustment, but (whether or not notice is given) such adjustment shall be effective and binding for all purposes of the Plan.

#### **Section 9. &nbsp;&nbsp;&nbsp;&nbsp; Amendment and Termination of Plan** 
The Board of Directors may amend or terminate this Plan at any time and in any manner, provided, however, that no such amendment or termination shall deprive the recipient of any Award theretofore granted under this Plan, without the consent of such recipient, of any of his or her rights thereunder or with respect thereto. In addition, the Committee may correct any defect, supply any omission, or reconcile any inconsistency in any award agreement in the manner and to the extent it

#### **Section 10. &nbsp;&nbsp;&nbsp;&nbsp; Effective Date of Plan** 
This Plan, as amended and restated, shall be effective as of April 29, 2026 provided, however, that no Common Shares may be issued under this Plan until it has been approved, directly or indirectly, by the affirmative votes of the holders of a majority of the securities of the Company present, or represented, and entitled to vote at a meeting duly held in accordance with the laws of the State of Delaware.

 until, in the opinion of counsel for the Company, all applicable requirements of federal, state and other securities laws, and the
 regulations promulgated thereunder, and any applicable listing requirements of any stock exchange on which shares of the same class
 are then listed, shall have been fully complied with. The Company shall not be required to register in a Participant's name
 or deliver any Common Shares prior to the completion of any registration or qualification of such shares under any foreign, federal,
 state or local law or any ruling or regulation of any government body which the Committee shall determine to be necessary or advisable.
 To the extent the Company is unable to or the Committee deems it infeasible to obtain authority from any regulatory body having jurisdiction,
 which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Common Shares hereunder,
 the Company and its subsidiaries shall be relieved of any liability with respect to the failure to issue or sell such Common Shares
 as to which such requisite authority shall not have been obtained. No Award shall be exercisable and no Common Shares shall be issued
 and/or transferable under any other Award unless a registration statement with respect to the Common Shares underlying such Award
 is effective and current or the Company has determined that such registration is unnecessary.

(b) It is the Company's intent that the Plan shall comply in all respects with Rule 16b-3 promulgated
 under the Exchange Act, as such Rule may be amended from time to time. If any provision of the Plan is found not to be in compliance
 with Rule 16b-3 of the Exchange Act, such provision shall be null and void.

(c) The Committee may provide that the Common Shares issued upon exercise of an Award or otherwise subject
 to or issued under an Award shall be subject to such further agreements, restrictions, conditions or limitations as the Committee
 in its discretion may specify prior to the exercise of such Award or the grant, vesting or settlement of such Award, including without
 limitation, conditions on vesting or transferability, forfeiture or repurchase provisions and method of payment for the Common Shares
 issued upon exercise, vesting or settlement of such Award (including the actual or constructive surrender of Common Shares already
 owned by the Participant) or payment of taxes arising in connection with an Award. Without limiting the foregoing, such restrictions
 may address the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any Common
 Shares issued under an Award, including without limitation (i) restrictions under an insider trading policy or pursuant to applicable
 law, (ii) restrictions designed to delay and/or coordinate the timing and manner of sales by Participant and holders of other Company
 equity compensation arrangements, (iii) restrictions as to the use of a specified brokerage firm for such resales or other transfers
 and (iv) provisions requiring Shares to be sold on the open market or to the Company in order to satisfy tax withholding or
 other obligations.

#### **Section 12. &nbsp;&nbsp;&nbsp;&nbsp; Miscellaneous** 
&nbsp;&nbsp;&nbsp;&nbsp;(a) Neither the adoption of this Plan by the Board nor the submission of this Plan to the
 shareholders of the Company for approval shall be construed as creating any limitations on the power of the Board or the Committee
 to adopt such other incentive arrangements as either may deem desirable, including without limitation, the granting of retention
 shares or stock options otherwise than under this Plan, and such arrangements may be either generally applicable or applicable only
 in specific cases.

(b) This Plan and any agreements or other documents hereunder shall be interpreted and construed in accordance
 with the laws of the State of Delaware and applicable federal law. Any reference in this Plan or in the agreement or other document
 evidencing any Awards to a provision

|  | of law or to a rule or regulation shall be deemed to include any successor law, rule or regulation of similar effect or applicability. |
| (c) | Nothing in this Plan or an Award agreement shall interfere with or limit in any way the right of the Company, its subsidiaries and/or its affiliates to terminate any Participant's employment, service on the Board or service for the Company at any time or for any reason not prohibited by law, nor shall this Plan or an Award itself confer upon any Participant any right to continue his or her employment or service for any specified period of time. Neither an Award nor any benefits arising under this Plan shall constitute an employment contract with the Company, any subsidiary and/or its affiliates. Subject to Sections 6 and 10, this Plan and the benefits hereunder may be terminated at any time in the sole and exclusive discretion of the Board without giving rise to any liability on the part of the Company, its subsidiaries and/or its affiliates. |
| (d) | Except as otherwise provided by the Committee in the Award agreement, Awards may be forfeited if the Participant terminates his or her employment with the Company, a subsidiary or an affiliate for any reason. |
| (e) | To the extent any payment under this Plan is considered deferred compensation subject to the restrictions contained in Section 409A of the Code, such payment may not be made to a specified employee (as determined in accordance with a uniform policy adopted by the Company with respect to all arrangements subject to Section 409A of the Code) upon "separation from service" (within the meaning of Section 409A of the Code) before the date that is three months after the specified employee's separation from service (or, if earlier, the specified employee's death). Any payment that would otherwise be made during this period of delay shall be accumulated and paid on the sixth month plus one day following the specified employee's separation from service (or, if earlier, as soon as administratively practicable after the specified employee's death). |
| (f) | The Plan is intended to be an unfunded plan. Participants are and shall at all times be general creditors of the Company with respect to their Awards. If the Committee or the Company chooses to set aside funds in a trust or otherwise for the payment of Awards under the Plan, such funds shall at all times be subject to the claims of the creditors of the Company in the event of its bankruptcy or insolvency. |
| (g) | All obligations of the Company under the Plan with respect to Awards granted hereunder shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. |
| (h) | Subject to the terms and conditions of the Plan, the Committee may provide that any Participant and/or any Award, including any Common Shares subject to an award, will be subject to any recovery, recoupment, clawback and/or other forfeiture policy maintained by the Company from time to time. |
| (i) | To the extent required by applicable federal, state, local or foreign law, a Participant shall be required to satisfy, in a manner satisfactory to the Company, any withholding tax obligations that arise by reason of a stock option exercise, disposition of Common Shares issued under an Incentive Stock Option, the vesting of or settlement of an Award, an election pursuant to Section 83(b) of the Code or otherwise with respect to an Award. To the extent a Participant makes an election under Section 83(b) of the Code, within ten days of filing such election with the Internal Revenue Service, the Participant must notify the Company in writing of such election. The Company and its subsidiaries shall not be required to issue Common Shares, make any payment or to recognize the transfer or disposition of Common Shares until all such obligations are satisfied. |
| (j) | Each Award may not be sold, transferred for value, pledged, assigned, or otherwise alienated or hypothecated by a Participant other than by will or the laws of descent and distribution, and each stock option or stock appreciation right shall be exercisable only by the Participant during his or her lifetime. Notwithstanding the foregoing, outstanding stock options may be exercised following the Participant's death by the Participant's beneficiaries or as permitted by the Board of Directors and/or Committee. Further, and notwithstanding the foregoing, to the extent permitted by the Board of Directors and/or Committee, the person to whom an Award is initially granted ("Grantee") may transfer an Award to any "family member" of the Grantee (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, (i) as a condition thereof, the transferor and the transferee must execute a written agreement containing such terms as specified by the Board of Directors and/or Committee, and (ii) the transfer is pursuant to a gift or a domestic relations order to the extent permitted under the General Instructions to Form S-8. Except to the extent specified otherwise in the agreement the Board of Directors and/or Committee provides for the Grantee and transferee to execute, all vesting, exercisability and forfeiture provisions that are conditioned on the Grantee's continued employment or service shall continue to be determined with reference to the Grantee's employment or service (and not to the status of the transferee) after any transfer of an Award pursuant to this Section 12(j), and the responsibility to pay any taxes in connection with an Award shall remain with the Grantee notwithstanding any transfer other than by will or intestate succession. |
| (k) | Awards granted under the Plan and/or communications regarding the Plan and any Award under the Plan may be made by sent via electronic delivery through an online or electronic system established and maintained by the Corporation or a third party designated by the Corporation. |
| (l) | The Board of Directors shall have the authority, subject to the express limitations of the Plan, to create sub-plans hereunder necessary to comply with laws and regulations of any foreign country in which the Company may seek to grant an Award to a person eligible under Section 2. |
