2024 marked Ducommun’s 175th anniversary as the oldest 
continuously operating company in California and I wanted 
to personally thank all our shareholders for their support and 
contribution to the company’s success! I am happy to report 
that shareholders were the beneficiaries of a 24% year over year 
increase in market capitalization and a 22% improvement in the 
stock price during 2024. A strong three year total shareholder 
return (TSR) percentage was at the 79th percentile versus the 
R2000 as management continued to build upon the VISION 2027 
game plan we introduced back in December of 2022 along with 
strong operational leadership and effective cost management.
Dear Fellow Shareholders,
Stephen G. Oswald
Chairman, President and Chief Executive Officer
Vision 2027 progress included increasing the revenue 
percentage from engineered products and aftermarket 
content, expanding our presence on key commercial 
aerospace platforms, executing our off-loading strategy 
with defense primes and consolidating our facility 
footprint. I also want to welcome our newest Board 
members, Daniel Korte and Daniel Boehle, to the 
Company. With their superior operational and financial 
expertise, we are thrilled with the fresh perspectives 
they bring to our Board.
At the same time and on behalf of our shareholders and 
leadership team, I want to convey our sincere gratitude 
and appreciation to Messrs. Dean Flatt and Robert 
Ducommun for their many years of invaluable service to 
the Board, and who will both be retiring as of this year’s 
annual meeting of shareholders. Finally, we are very 
excited about the unique value creation opportunities 
ahead for our shareholders as we start year 3 of the 
Vision 2027 Strategy.

Financial Performance
Ducommun posted revenues of $786.6 million in 2024, 
setting another new all-time record for the second 
consecutive year. We also had record gross margins, 
expanding 350 basis points over the prior year to a new 
all-time high of 25.1%. Our operating margins were 6.6%, 
delivering $52.2 million of operating income with a net 
income of $31.5 million. Non-GAAP adjusted operating 
income was $74.2 million or 9.4% in 2024, compared  
to $62.2 million or 8.2% in 2023. Adjusted EBITDA 
generation was also at a new all-time record for the 
second consecutive year in 2024, reaching $116.6 million 
compared to $101.5 million in 2023. Another bright  
spot in 2024 was our overall backlog being in excess of  
$1.0 Billion, to end at $1,060.8 million, led by Military and 
Space which was up almost $100 million, to $625 million.
We also made good progress on our restructuring program 
in 2024 and ceased manufacturing activities at our 
Monrovia, California facility and expect to close our 
Berryville, Arkansas facility during 2025. We are ramping up 
at the various receiving facilities to support the transition 
of products from Monrovia and Berryville and working to 
complete the certification process with our customers.  
We began realizing some of the expected benefits from the 
restructuring program during 2024. Once we fully complete 
the transition, we anticipate these actions will result in total 
annualized cost savings of $11.0 million to $13.0 million. 
In December 2022, we laid out our Vision 2027 Plan to 
investors and now at the end of year two, our financial 
performance shows that the Plan is working. Our margins 
have expanded and we have grown revenues despite 
significant headwinds in the commercial aerospace 
market. I am optimistic that Boeing’s progress on safety 
and quality control will allow them to regain stability and 
production growth in the second half of 2025 and into 
2026, which is great news for Ducommun and an 
inflection point for higher revenue.
* Under ASC 606, we define performance obligations 
as customer placed purchase orders with firm fixed 
price and firm delivery dates. The remaining 
performance obligations disclosed under ASC 606 
as of December 31, 2024 were $1,013 million. We 
define backlog as customer placed purchase orders 
and long-term agreements with firm fixed price 
and expected delivery dates of 24 months or less.

Ducommun Incorporated    2024 Annual Report

Ducommun was also recognized as part of an elite group 
of top performing suppliers by Lockheed Martin 
Aeronautics as a recipient of the Elite Supplier Award.  
The recognition is based on Ducommun having achieved 
outstanding performance levels in quality and delivery 
throughout 2023. The Elite Supplier Award recognizes 
the efforts of Ducommun’s world-class engineering and 
manufacturing performance center in Joplin, Missouri, 
which provides up to 90 different components, including 
harness assemblies for the center and wing fuel tanks, 
directly and indirectly to Lockheed Martin Aeronautics for 
the F-35 platform and these are utilized across all three 
variants of the aircraft.
Ducommun earned the Northrop Grumman Mission 
Systems (“NGMS”) Platinum Supplier Designation, 
recognizing our continuous high level of quality and 
on-time delivery performance in providing micro power 
supplies to ground-based radar systems used to 
eliminate missile threats to the warfighter. The micro 
power supplies are produced at Ducommun’s world-
class circuit card assembly engineering and 
manufacturing performance center in Tulsa, Oklahoma.
For the second consecutive year, Ducommun received a 
Gold ‘Partner2Win’ medallion from BAE Systems, 
recognizing exceptional performance and commitment 
to operational excellence in 2024. BAE Systems’ 
‘Partner2Win’ program recognizes suppliers for their 
achievements in operations, quality and procurement.  
As part of the program, BAE Systems maintains a close 
relationship with suppliers like Ducommun and creates 
an environment where we can share best practices, 
learnings and innovative solutions to problems.
Shifting to our environmental stakeholders, Ducommun’s 
performance center in Appleton, WI received a Recycling 
Excellence Award from the Wisconsin Department of 
Natural Resources (DNR) in the ‘Projects and Initiatives’ 
category. The team launched a zero-landfill initiative that 
converts green fuel sources into pellets to replace coal at 
local power plants, helping to reduce coal emissions. 
Since the program’s inception, the Appleton performance 
center has successfully recycled over 32 tons of material!
Finally, Ducommun is proud to again be named  
to Newsweek magazine’s list of Most Responsible 
Companies for 2025, announced in December of  
2024. This is our second year earning this designation  
in recognition of our unwavering commitment to 
corporate social responsibility and long-term 
sustainability. Newsweek’s annual ranking of America’s 
Most Responsible Companies focuses on a holistic  
view of corporate responsibility that considers all three 
pillars of ESG: Environment, Social, and Corporate 
Governance. The analysis is based in part on 30 KPIs 
researched for the top 2,000 public companies by 
revenue headquartered in the United States.

Environmental, Health & Safety
EMPLOYEE SAFETY
Ducommun tracks safety key performance indicators such 
as the number of lost-time and total recordable incidents 
incurred by our employees to assess the effectiveness of 
our health and safety programs. In 2024, our Total 
Recordable Incident Rate was 0.34, a decrease of 86% 
compared to the baseline year of 2019, or 44% compared 
to 2023. Additionally, our Lost Time Injury Rate has 
decreased by 89% compared to 2019 levels.
We continued tracking leading indicators such as first aid 
and near miss incidents to prevent accidents before they 
occur and to help reinforce our safety-first culture. 
Additionally in 2024, we began integrating behavior-
based safety observations into our leading indicators of 
safety metrics. This enhancement enables us to focus on 
preventing unsafe behaviors, reinforcing our safety-first 
culture and reducing the risk of incidents before they occur. 
GREENHOUSE GAS EMISSIONS REDUCTIONS
Since publishing our first Corporate and Environmental 
Responsibility Report (“CER”) report for FY 2020,  
we have worked diligently to enhance the transparency 
of our corporate responsibility program and related 
disclosures. For instance, we made significant 
improvements to our GHG calculation methodologies to 
align more closely with GHG protocol recommendations, 
which includes the critical practice of reviewing our GHG 
baseline when appropriate. 
As illustrated in the chart below, there was a 50% 
decrease in our combined Scope 1 and 2 greenhouse gas 
emissions in 2024 compared to 2019. To effectively 
manage and address climate risks and reduce future 
greenhouse gas emissions, we based our approach to the 
environmental portion of our CER program on four key 
pillars: energy efficiency, waste reduction, wastewater 
efficiency, and accurate, verifiable, and auditable CER 
data. These pillars are linked to resource conservation  
in production, driving reductions in GHG emissions, 
uncovering cost-savings opportunities, and ensuring 
sustainable long-term value for our stakeholders. 
Ducommun continues to prioritize the responsible 
management of hazardous and non-hazardous waste, 
investing significant resources to help reduce our waste 
footprint by finding innovative ways to recycle, reuse  
and extend the service life of materials throughout our 
operations. By recycling and reusing such materials, we 
reduce Scope 3 GHG emissions by decreasing the number of 
transportation miles driven by third-party waste haulers 
and decreasing the amount of virgin materials needed.

Ducommun Incorporated    2024 Annual Report

Celebrating 175 Years of Innovation & Community 
Ducommun reached a significant milestone in 2024  
as we celebrated our 175th continuous year in business. 
Throughout the year, employees across the company came 
together for special events to celebrate the momentous 
occasion. We used the opportunity to recognize and 
celebrate our founder, Charles L. Ducommun, who came 
to America as an immigrant and later traveled a grueling 
nine months from Arkansas to Los Angeles, California 
where he founded Ducommun in 1849. 
On October 11th, 2024, Ducommun’s Chairman, President 
and CEO, Stephen G. Oswald further marked the 
milestone year by ringing the Closing Bell at the New York 
Stock Exchange alongside our board of directors and 
corporate officers. In ringing the Closing Bell and in the 
spirit of innovation and community, Ducommun looks 
forward to continuing our significant contributions to the 
aerospace and defense industry, driving shareholder 
value and making a difference for all stakeholders.

Employee Support & Engagement
At Ducommun, we prioritize the overall well-being of our 
employees. Beyond traditional health and wellness, we 
continue to expand our offerings with unique benefits 
designed to support employees and their families 
through all stages of life.
EMPLOYEE ASSISTANCE PROGRAM
We are proud to provide all Ducommun employees and their 
families with access to our robust Employee Assistance 
Plan (EAP). Our EAP connects employees with resources 
to support their emotional and mental well-being as well 
as benefits for professional growth, financial stability, 
physical health, and family life. Most notably, the EAP 
provides access to 24/7 unlimited telephonic counseling 
services by Master’s or Ph.D.-level mental health 
professionals. In 2024, our members utilized the EAP over 
520 times including activities in coaching and counseling, 
self help resources, and online training. These services 
are completely and 100% confidential and available to all 
employees and their families at no cost, even those that 
are not enrolled in our Company medical plan.
FINANCIAL PLANNING & GROWTH
Our Employee Stock Purchase Plan (ESPP) remains a 
valued employee benefit, with over 500 employees taking 
advantage of the opportunity to further benefit from the 
Company’s success through ownership of Ducommun 
shares. This represents a 28% increase in participation 
since the program’s inception in 2019. On average, 
participants in 2024 enjoyed a discount of more than $14 
off the fair market value of the stock at time of purchase. 
In 2024, employees continued to take full advantage of 
our 401(k) program and company match with over 91% of 
our employees participating in the plan. Our employees 
continue to take important steps towards saving for 
retirement and building a secure financial future, electing 
payroll contributions that significantly exceed the 
benchmark for plans of our size.
Finally, Ducommun supported employees’ educational 
goals through tuition reimbursement payments totaling 
more than $30,000. Our tuition reimbursement program 
is used to lessen the financial burden of coursework for 
employees in various functional departments, including 
engineering, accounting, quality, sales, supply chain,  
and logistics.
DUCOMMUN SCHOLARS PROGRAM
The Ducommun Scholarship program is a merit-based, 
renewable program available exclusively to our full-time 
employees’ children and grandchildren attending a 
four-year college or university or a two-year accredited 
technical or vocational college. In 2024, we continued to 
expand the program awarding a record 92 scholarships, 
including 40 new awards and 52 renewed scholarships. 
The total value of the scholarships awarded in 2024 was 
$259,000, up 9% from scholarships awarded in 2023.  
We value the opportunity to celebrate the achievements 
of our talented Ducommun family members, inspire 
students to pursue their education, and contribute to  
the success of future generations.
CONGRATULATIONS 2024
DUCOMMUN SCHOLARS

California to pursue his dream. 175 years later, I am thrilled that we can support future generations  
in pursuit of their dreams and aspirations!! I would also like to acknowledge the parents and

National Football League and the University of  
California, Irvine’s UCI Samueli School of Engineering. 
STEM on the Sidelines™ is a regional competition that 
promotes STEM (Science Technology Engineering & 
Mathematics) education in high schools. This year, the 
competition included 20 teams from 14 Los Angeles and 
Orange County schools at the Chargers’ new, state-of-
the art training facility “The Bolt” in El Segundo, CA.  
The teams were tasked with designing and building  
robot rovers that were put through activities similar  
to the NFL combine, focusing on speed and agility.  
The winning teams were honored with on field 
recognition at the Los Angeles Chargers home  
game on December 19th, 2024.
THE AMERICAN ROCKETRY CHALLENGE
Ducommun served as a Gold Sponsor for the 2024 
American Rocketry Challenge, the world’s largest 
student rocketry competition featuring 900 teams from 
45 states. The National Championship was awarded to 
Tharptown High School of Russellville, Alabama who 
continued on to represent the United States at the 
International Rocketry Challenge at the Farnborough 
International Airshow in July, finishing in second place!  
To date, the American Rocketry Challenge has inspired 
more than 100,000 middle and high school students to 
explore education and careers in STEM, fostering 
leadership, teamwork, and problem-solving skills 
critically needed in our industry and beyond.

Ducommun Incorporated    2024 Annual Report

NATIONAL MANUFACTURING DAY
Ducommun’s performance centers across the country 
participated in our 4th Annual National Manufacturing 
Day (MFGDay) event in October. This event, organized 
nationally by the Manufacturing Institute and the 
National Association of Manufacturers, presents unique 
opportunities for middle and high school students to 
learn about careers in manufacturing after completing 
their education. Our performance centers welcomed the 
next generation of innovators for plant tours, 
presentations, and hands-on activities. Students were 
also given the opportunity to meet our employees and 
hear about their successes in the industry. Some of our 
employees attended local community student events, 
highlighting manufacturing careers for participants. In 
total, our performance centers connected with over 
1,500 students through these events. 
THE DUCOMMUN FOUNDATION
The Ducommun Foundation was founded in 2019 and 
operates as the philanthropic arm of Ducommun to 
address various community and humanitarian needs.  
This year, our donations benefited local communities  
as well as Veteran’s assistance programs with over  
$75,000 pledged to United Way, American Legion  
House, Fisher House Foundation, and American  
Battle Monuments Commission. 
DUCOMMUN AND UNITED WAY
Ducommun further solidified our partnership with United 
Way in 2024 with employees donating over $65,000 
through our company-wide “Ducommun Cares” giving 
campaign. We again participated as a Champion Sponsor 
for Orange County United Way’s “Rally for Change”, 
where we were also honored with a nomination for the 
Medium-Sized Company Corporate Giving Climber 
Award. Ducommun served as an Anniversary Sponsor to 
Orange County United Way’s Centennial Gala, celebrating 
100 Years of Impact in local communities. This once-in-a-
century celebration raised over $850,000 for United Way 
and the communities they support. 
Veterans from American Legion Post 33 Color Guard came 
out to present the California and United States flags at 
Ducommun’s 175th anniversary celebration in Southern 
California on May 15th, 2024. Ducommun is a proud 
supporter of our country and of the men and women  
who serve and protect our freedom.

shareholders, and other stakeholders for their continued 
support, I am very proud of our work! Vision 2027 
continues to be the focus as the company moves into 
2025 and we are very encouraged with the Commercial 
Aerospace build rate forecasts going higher along with a 
current strong backlog in Ducommun’s Defense business, 
the future is bright.

Building Bridges for Veterans
Ducommun is thrilled to be an approved corporate 
partner of DOD SkillBridge, a program within the 
Department of Defense that allows transitioning service 
members to gain valuable civilian work experience 
through internships, apprenticeships, or specific industry 
training during the final months of their military service. 
Each year approximately 200,000 members of the  
U.S. Armed Forces will leave active duty and re-enter  
the civilian work force or pursue higher education.  
By connecting these exiting service members with 
industry partners, DOD SkillBridge helps to bridge the 
gap between military life and civilian employment  
while providing military pay and benefits during their 
participation. In 2024, we were able to initiate multiple 
internships through the program in areas such as HR  
and Engineering. Participants were connected with 
experienced veterans within our organization as part  
of our veteran-to-veteran mentorship program. We are 
honored to welcome these veterans into the aerospace 
and defense industry and are appreciative of the valuable 
skills, knowledge, and experience that they bring to our 
industry and our company.

PART I
ITEM 1. BUSINESS
GENERAL
Ducommun Incorporated (“Ducommun,” “the Company,” “we,” “us” or “our”) is a leading global provider of engineering 
and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the 
aerospace and defense (“A&D”), industrial, medical and other industries (collectively, “Industrial”). Ducommun 
differentiates itself as a full-service solution-based provider, offering innovative, value-added proprietary products and 
manufacturing solutions to our customers in our primary businesses of electronics, structures, and integrated solutions. We 
operate through two primary business segments:  Electronic Systems and Structural Systems. We are the successor to a 
business that was founded in California in 1849 and reincorporated in Delaware in 1970.
ACQUISITIONS
Acquisitions have been an important element of our growth strategy. We have supplemented our organic growth by 
identifying, acquiring and integrating acquisition opportunities that result in broader, more sophisticated product and service 
offerings while diversifying and expanding our customer base and markets.
For example, in April 2023, we acquired 100% of the outstanding equity interests of BLR Aerospace L.L.C. (“BLR”), a 
privately-held leading provider of aerodynamic systems that enhance the productivity, performance, and safety of rotary and 
fixed-wing aircraft on commercial and military platforms. The initial purchase price was $115.0 million, net of cash acquired. 
We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. We utilized the 2022 Revolving

AEROSPACE AND DEFENSE END-USE MARKETS OVERVIEW
Our largest end-use markets are the aerospace and defense markets and our revenues from these markets represented 96% of 
our total net revenues in 2024. These markets are serviced by suppliers which are stratified, from the highest value provided 
Table of Contents

to the lowest, into four tiers: original equipment manufacturers (“OEMs”), Tier One, Tier Two, and Tier Three. The OEMs 
provide the highest value and are also known as prime contractors (“Primes”). We derive a significant portion of our revenues 
from subcontracts with OEMs. As the Primes for various programs and platforms, the OEMs sell to their customers, who 
may include, depending upon the application, the U.S. Federal Government, foreign, state and local governments, global 
commercial airline carriers, regional jet carriers and various other customers. The OEMs also sell to global leasing companies 
that lease commercial aircraft. A significant portion of our revenues is earned from subcontracts with the Primes. Tier One 
suppliers manufacture aircraft sections and purchase assemblies. Tier Two suppliers provide more complex, value-added 
parts and may also assume more design risk, manufacturing risk, supply chain risk and project management risk than Tier 
Three suppliers. Tier Three suppliers principally provide components or detailed parts. We currently compete with Tier One, 
Tier Two, and Tier Three suppliers. Our business growth strategy is to differentiate ourselves from competitors by providing 
more complex assemblies to our customers as a higher value added supplier.
Commercial Aerospace End-Use Market
The commercial aerospace end-use market is highly cyclical and is impacted by the level of global air passenger traffic in 
general, which in turn is influenced by global economic conditions, fleet fuel and maintenance costs, geopolitical 
developments, pandemics, supply chain issues, and inflationary forces. Revenues from the commercial aerospace end-use 
market represented 42% of our total net revenues for 2024.
The elevated inflation rate, high interest rates, supply chain issues, geopolitical developments, and other events have 
contributed and/or continues to contribute to a general slowdown in the global economy. Further, one of our largest 
customers, The Boeing Company (“Boeing”), was notified by the Federal Aviation Administration (“FAA”) in early January 
2024 it initiated an investigation into Boeing’s quality control system. This notification was followed by the FAA announcing 
actions to increase its oversight of Boeing as well as not approving production rate increases or additional production lines 
for the 737 MAX until it is satisfied that Boeing is in full compliance with required quality control procedures. In July 2024, 
Boeing also pled guilty to conspiracy fraud charges, which may result in additional external oversight on its manufacturing 
and quality control process. Further, in September 2024, the International Association of Machinists and Aerospace Workers 
District 751 voted to initiate a labor strike affecting more than 30,000 Boeing manufacturing employees primarily located in 
Washington state, and the manufacturing employees, after rejecting the contract offer in October, voted to approve the 
revised contract offer in November 2024. The combination of these factors has, in turn, created a significant challenge for 
some of our customers and the entire commercial aerospace manufacturing and services sector. Airline financial 
performance, which also plays a role in the demand for new capacity, has been adversely impacted by the aforementioned 
issues. According to the International Air Transport Association (“IATA”), it is estimating industry-wide profits of $31.5 
billion for 2024, an increase from its forecast of $25.7 billion a year ago. For 2025, IATA is forecasting $36.6 billion in 
profits for the industry globally. Thus, the overall outlook continues to stabilize as we face uncertainties in the environment in 
the near-to medium-term as airlines are facing persistently high and volatile costs. The global economy is expecting a 
continued easing of inflation and interest rates, with regional economic and geopolitical difficulties adding uncertainty to the 
outlook and the financial viability of some airlines and regions. 
In The Boeing Company’s (“Boeing”) 2024 Annual Report on Form 10-K filed with the Securities and Exchange 
Commission (the “SEC”), they indicated that in 2024, global air traffic continued to expand beyond 2019 levels with 
domestic travel continuing to be the most robust and the single-aisle market following closely. International travel also 
surpassed pre-pandemic levels during 2024 and the wide-body market continues to improve with international travel 
recovery. The transition in the international commercial market from recovery to normal market conditions is continuing to 
progress as China international travel remains below 2019 levels. Overall, Boeing is experiencing strong demand from its 
airline customers globally.
The long-term outlook for the industry remains positive due to the fundamental drivers of air travel demand:  economic 
growth, increasing propensity to travel due to increased trade, globalization and improved airline services driven by 
liberalization of air traffic rights between countries. Boeing’s commercial market outlook forecast projects a three and two 
tenths percent growth rate in the global fleet over a 20 year period. Based on long-term global economic growth projections 
of two and six tenths percent average in annual gross domestic product (“GDP”) growth, Boeing projects demand for 43,975 
new airplanes over the next 20 years. However, the industry remains vulnerable to various developments including fuel price 
spikes, credit market fluctuations, acts of terrorism, natural disasters, conflicts, epidemics, pandemics, and increased global 
environmental regulations. We believe we are well positioned given our product capabilities, investment in inventories and 
contract assets, and our initiatives to increase operating efficiencies to participate in the near term recovery and the long term 
projected growth rate for commercial air traffic and build rates for large commercial aircraft for the airframe manufacturing

industry. If the recovery is slower than anticipated or any of those various developments occur, it could have a material 
adverse effect on our results of operations, financial position, and/or cash flows.
Defense End-Use Market
Our defense end-use market includes products used in military and space, including technologies and structures applications. 
The defense end-use market is highly cyclical and is impacted by the level of government defense spending. Government 
defense spending is impacted by national defense policies and priorities, political climates, fiscal budgetary constraints, U.S. 
Federal budget deficits, projected economic growth and the level of global military or security threats, or other conflicts. 
Revenues from the military and space end-use market in 2024 represented 54% of our total net revenues during 2024.
On December 21, 2024, the U.S. Government enacted a continuing resolution (“CR”) to keep the government funded through 
March 14, 2025 while the Congress works to enact full year fiscal year 2025 (“FY25”) appropriation bills or an additional CR 
to fund government departments and agencies after March 14, 2025. We, and a number of our customers rely on the U.S. 
Government in various aspects of our defense and commercial businesses. In the event of a shutdown, requirements to 
furlough employees in the U.S. Department of Defense (“U.S. DoD”) or other government agencies could result in payment 
delays, impair our ability to perform work on existing contracts or otherwise impact our operations, negatively impact future 
orders, and/or cause other disruptions or delays.
The U.S. Government could experience a disruption to its operations and/or payments in 2025 as a result of the U.S. Treasury 
exhausting extraordinary measures after reaching its debt limit. In addition, U.S. Government discretionary spending in FY24 
and FY25, including defense spending, was capped by the Fiscal Responsibility Act of 2023 (“FRA23”). If a CR for FY25 is 
in place on April 30, 2025, it would trigger a sequester under the FRA23. These potential disruptions, and any other broader 
macroeconomic impacts, could affect our current programs and contracts and have a material effect on our financial position, 
results of operations and/or cash flows. For additional information related to our revenues from customers whose principal 
sales are to the U.S. Government and our direct sales to the U.S. Government, see “Risk Factors” contained within Part I, 
Item 1A of this Annual Report on Form 10-K (“Form 10-K”).
INDUSTRIAL END-USE MARKETS OVERVIEW
Our industrial, medical and other (collectively, “Industrial”) end-use markets are diverse and are impacted by the customers’ 
needs for increasing electronic content and a desire to outsource. Factors expected to impact these markets include capital and 
industrial goods spending and general economic conditions. Our products are used in heavy industrial manufacturing systems 
and certain medical applications. Revenues from the Industrial end-use markets were 4% of our total net revenues during 
2024. 
We believe our business in these markets in the long-term, is stable and we are well positioned in these markets even though 
the elevated inflation rate, high interest rates, and supply chain issues has had and will continue to have an impact on our 
business.
SALES AND MARKETING
Our commercial revenues are substantially dependent on airframe manufacturers’ production rates of new aircraft. Deliveries 
of new aircraft by airframe manufacturers are dependent on the demand and financial capacity of its customers, primarily 
airlines and leasing companies, to purchase the aircraft. Thus, revenues from commercial aircraft could be affected as a result 
of changes in new aircraft orders, or the cancellation or deferral by airlines of purchases of ordered aircraft. Further, our 
revenues from commercial aircraft programs could be affected by changes in our customers’ inventory levels and changes in 
our customers’ aircraft production build rates as a result of changing demand by their end customer or in order to comply 
with regulatory requirements. Due to the effects from the supply chain issues or regulatory compliance requirements, while 
both major large aircraft manufacturers, Boeing and Airbus SE (“Airbus”), expect improved build rates, it will take longer to 
reach pre-COVID-19 pandemic levels. While the ramp up in production and demand will be slower in the near and medium 
future, we will continue to identify opportunities to expand our presence and offerings with both major large aircraft 
manufacturers and their supply chain.
Military components manufactured by us are employed in many of the country’s front-line fighters, bombers, rotary-wing 
aircraft and support aircraft, as well as land and sea-based applications. Our defense business is diversified among a number 
of military manufacturers and programs. In the space sector, we are expanding our presence with unmanned aerial vehicles 
and continue to support various satellite programs.

Our sales into the Industrial end-use markets are customer focused in various markets and driven primarily by their capital 
spending and manufacturing outsourcing demands.
We continue to broaden and diversify our customer base in the end-use markets we serve by providing innovative product 
and service solutions by drawing on our core competencies, experience and technical expertise. Net revenues related to 
military and space, commercial aerospace, and Industrial end-use markets in 2024 and 2023 were as follows:
Many of our contracts are firm fixed price contracts subject to termination at the convenience of the customer (as well as for 
default). In the event of termination for convenience, the customer generally is required to pay the costs we have incurred and 
certain other fees through the date of termination, plus a reasonable profit. Larger, long-term government subcontracts may 
have provisions for milestone payments, progress payments or cash advances for purchase of inventory.
Our marketing efforts primarily consist of developing strong, long-term relationships with our customers, which provide the 
basis for future sales. These close relationships allow us to gain a better insight into each customer’s business needs, identify 
ways to provide greater value to the customer, and allow us to be designated early in the design process for various products 
and/or high volume products.
SEASONALITY
The timing of our revenues is governed by the purchasing patterns of our customers, and, as a result, we may not generate 
revenues equally during the year. However, no material portion of our business is considered to be seasonal.
MAJOR CUSTOMERS
We currently generate the majority of our revenues from the aerospace and defense industries. As a result, we have 
significant revenues from certain customers. Boeing and RTX Corporation (f/k/a Raytheon Technologies Corporation) 
(“RTX”) were our largest customers, with Boeing generating 8.2% and RTX generating 18.5% of our 2024 net revenues. 
Revenues from our top 10 customers, including Boeing and RTX, were 60% of total net revenues during 2024. Net revenues 
by major customer for 2024 and 2023 were as follows:

Net revenues from our customers, except the U.S. Government, are diversified over a number of different military and space, 
commercial aerospace, industrial, medical and other products. For additional information on revenues from major customers, 
see Note 17 to our consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K.
RESEARCH AND DEVELOPMENT
We perform concurrent engineering with our customers and product development activities under our self-funded programs, 
as well as under contracts with others. Concurrent engineering and product development activities are performed for 
commercial, military and space applications.
RAW MATERIALS AND COMPONENTS
Raw materials and components used in the manufacturing of our products include aluminum, titanium, steel and carbon 
fibers, as well as a wide variety of electronic interconnect and circuit card assemblies and components. These raw materials 
are generally available from a number of suppliers and are generally in adequate supply. However, from time to time, and due 
to the lingering supply chain issues, we have experienced increases in lead times and limited availability of various items 
including aluminum, titanium and certain other raw materials and/or components. Moreover, certain components, supplies 
and raw materials for our operations are purchased from single source suppliers and occasionally, directed by our customers. 
In such instances, we strive to develop alternative sources and design modifications to minimize the potential for business 
interruptions.
COMPETITION
The markets we serve are highly competitive, and our products and services are affected by varying degrees of competition. 
We compete worldwide with domestic and international companies in most markets. These companies may have competitive 
advantages as a result of greater financial resources, economies of scale and bundled products and services that we do not 
offer. Additional information related to competition is discussed in Risk Factors contained within Part I, Item 1A of this Form 
10-K. Our ability to compete depends principally upon the breadth of our technical capabilities, the quality of our goods and 
services, competitive pricing, product performance, design and engineering capabilities, new product innovation, the ability 
to solve specific customer needs, and customer relationships.
PATENTS AND LICENSES
We have several patents, but we do not believe that our operations are dependent upon any single patent or group of patents. 
In general, we rely on technical superiority, continual product improvement, exclusive product features, superior lead time, 
on-time delivery performance, quality, and customer relationships to maintain our competitive advantage.
REMAINING PERFORMANCE OBLIGATIONS AND BACKLOG
We define performance obligations as customer placed purchase orders (“POs”) with firm fixed price and firm delivery dates. 
The majority of the long-term agreements (“LTAs”) we enter into do not meet the definition of a contract under Accounting 
Standards Codification 606 (“ASC 606”) and thus, the backlog amount may or may not be greater than the remaining 
performance obligations amount as defined under ASC 606. Revenue based on remaining performance obligations is subject 
to delivery delays or program cancellations, which are beyond our control. Remaining performance obligations were $1,012.6

million at December 31, 2024. We anticipate recognizing an estimated 70% or $709.0 million of our remaining performance 
obligations during 2025.
We define backlog as potential revenue that is based on customer placed POs and LTAs with firm fixed price and expected 
delivery dates of 24 months or less. 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 
several programs to a greater extent, than our net revenues. As a result of these factors, trends in our overall level of backlog 
may not be indicative of trends in our future net revenues. Backlog was $1,060.8 million at December 31, 2024, compared to 
$993.6 million at December 31, 2023. The increase in backlog was primarily in the military and space end-use markets, 
partially offset by a decrease in the commercial aerospace end-use markets and the industrial end-use markets. 
ENVIRONMENTAL MATTERS
Our business, operations and facilities are subject to numerous stringent federal, state and local environmental laws and 
regulations issued by government agencies, including but not limited to the Environmental Protection Agency (“EPA”) and 
similar state agencies. Among other matters, these regulatory authorities impose requirements that regulate the emission, 
discharge, generation, management, transport and disposal of hazardous and non-hazardous materials, pollutants and 
contaminants. These regulations govern public and private response actions to hazardous or regulated substances that could 
be or have been released into the environment, or endanger human health and safety, and they require us to obtain and 
maintain licenses and permits in connection with our operations. We may also be required to investigate and remediate the 
effects of a release or the possible disposal of materials at sites associated with our past and present operations. Additionally, 
this extensive regulatory framework imposes significant compliance burdens and risks on us. For example, in 2023, 
California passed two wide-reaching bills that are likely to impose significant and mandatory climate-related reporting 
requirements for large public and private companies doing business in the state. The bills were subsequently amended in 
2024 and will ultimately likely require annual disclosure of audited Scope 1 and 2 greenhouse gas (“GHG”) emissions and 
biennial disclosure related to certain climate risks, beginning in January 2026 and subject to final regulations expected to be 
promulgated by the California Air Resources Board around or near July 2025. We anticipate that capital expenditures will 
continue to be required for the foreseeable future to upgrade and maintain our environmental compliance efforts, however, 
we currently do not expect such expenditures to be material in 2025 and the near term.
Structural Systems has been directed by California environmental agencies to investigate and take corrective action for 
groundwater contamination at its facilities located in Adelanto (a.k.a., El Mirage) and Monrovia, California. Based on 
currently available information, we have accrued $1.5 million at December 31, 2024 for our estimated liabilities related to 
these sites. For further information, see Note 16 in the accompanying notes to consolidated financial statements included in 
Part IV, Item 15(a) of this Form 10-K. In addition, see Risk Factors contained within Part I, Item 1A of this Form 10-K for 
certain risks related to environmental matters.
HUMAN CAPITAL
Our employees are critical to our success. We promote a culture of honesty, respect, trust, and teamwork through our Code of 
Business Conduct. Also, we have been engaged in a number of social matters and issues, both within the Company in our 
management of human capital, and externally with our community based initiatives.
Employee Safety and Health
The safety of our workforce remains our highest priority. To this end, we continue to focus on protecting the health and 
safety of our employees and maintaining a safe work environment.
In 2024, we continued to invest in infrastructure to improve internal safety protocols related to key processes and refined our 
health and safety software tools to track and engage our performance centers to further reduce our lost time and total 
recordable incident rates.
Human Capital Management
We promote fairness and equal opportunities through our employment practices and processes and continue to drive a merit-
based culture throughout our company. These priorities are demonstrated by fostering employees’ well-being and 
encouraging the sharing of ideas and unique perspectives, promoting innovation, creativity, collaboration and supporting the 
development, growth and advancement of individual contributions. In 2020, we partnered with the Fund II Foundation to 
utilize its innovative internX platform to provide access to highly qualified and diverse science, technology, engineering and 
math (“STEM”) students. We believe that broadening the diversity of our pool of potential qualified applicants at the intern 
Table of Contents

level will support our efforts at a diverse workforce reflective of the population and help us continue to develop a more 
diverse leadership team as our interns continue in their careers.
Talent Acquisition, Retention, and Development
We attract, develop, and retain employee talent by offering competitive compensation packages and fostering a culture of 
care about their well-being. In addition, we endeavor to be a proactive corporate citizen by being responsive and supportive 
of the needs of our employees to attract qualified talent. We strive to provide equal opportunities for advancement to all our 
employees within our company based on individual merit and award merit-based scholarships to the children and 
grandchildren of our employees so that they may develop the skills that will support their entry into the workforce. In 
addition, we have an Employee Stock Purchase Plan (“ESPP”) to provide employees the opportunity to share in the 
ownership of our company and benefit from our performance through the purchase of our company’s stock. The ESPP allows 
eligible employees to accumulate contributions through after-tax payroll deductions to purchase shares of our Company’s 
stock at a 15% discount and serves as one of the key retention mechanisms for our human capital.
Workforce Demographics
As of December 31, 2024, we had a highly skilled workforce of 2,180 employees, of which 268 are subject to a collective 
bargaining agreement expiring in April 2025. Historically, we have been successful in negotiating renewals to expiring 
agreements without material disruption of operating activities, and believe our relations with our employees are good. See 
Risk Factors contained within Part I, Item 1A of this Form 10-K for additional information regarding certain risks related to 
our employees.

other information regarding SEC registrants, including our company.
ITEM 1A. RISK FACTORS
Our business, financial condition, results of operations and cash flows may be affected by known and unknown risks, 
uncertainties and other factors. We have summarized below the significant, known material risks to our business. Additional 
risk factors not currently known to us or that we currently believe are immaterial may also impair our business, financial 
condition, results of operations and cash flows. Any of these risks, uncertainties and other factors could cause our future 
financial results to differ materially from recent financial results or from currently anticipated future financial results. The 
risk factors below should be considered together with the information included elsewhere in this Form 10-K as well as other 
required filings by us with the SEC.
CAPITAL STRUCTURE RISKS
Our indebtedness could limit our financing options, adversely affect our financial condition, and prevent us from 
fulfilling our debt obligations.
In July 2022, we completed a refinancing of our then existing debt by entering into a new term loan (“2022 Term Loan”) and 
a new revolving credit facility (“2022 Revolving Credit Facility”). The 2022 Term Loan is a $250.0 million senior secured 
loan that matures in July 2027. The 2022 Revolving Credit Facility is a $200.0 million senior secured revolving credit facility 
that matures in July 2027. The 2022 Term Loan and 2022 Revolving Credit Facility, collectively are the new credit facilities 
(“2022 Credit Facilities”). The terms of the 2022 Term Loan require us to make installment payments of 0.625% of the initial 
outstanding principal balance on a quarterly basis during years one and two, 1.250% during years three and four, and 1.875% 
during year five, on the last business day of each calendar quarter. In addition, the undrawn portion of the commitment of the 
2022 Revolving Credit Facility is subject to a commitment fee ranging from 0.175% to 0.275%, based upon the consolidated 
total net adjusted leverage ratio. 
Table of Contents

11

At December 31, 2024, we had a total of $243.2 million of outstanding long-term debt under the 2022 Credit Facilities. The 
total long-term debt was primarily the result of our acquisitions, including Lightning Diversion Systems, LLC (“LDS”) in 
September 2017, Certified Thermoplastics Co., LLC (“CTP”) in April 2018, Nobles Worldwide, Inc. (“Nobles”) in October 
2019, and BLR Aerospace, L.L.C. (“BLR”) in April 2023.
Our ability to obtain additional financing or complete a debt refinancing in the future may be limited. Should we not have 
ready access to capital markets, we may have to undertake alternative financing plans, such as selling assets; reducing or 
delaying scheduled expansions, acquisitions and/or capital investments; or seeking various other forms of capital. Our ability 
to complete reasonable alternative financing plans may be affected by circumstances and economic events outside of our 
control. We cannot ensure that we would be able to refinance our debt or enter into alternative financing plans in adequate 
amounts on commercially reasonable terms, terms acceptable to us or at all, or that such plans guarantee that we would be 
able to meet our debt obligations.
Our level of debt could:
•
limit our ability to obtain additional financing to fund capital expenditures, investments or acquisitions or other 
general corporate requirements;
•
require a portion of our cash flows to be dedicated to debt service payments instead of other purposes, thereby 
reducing the amount of cash flows available for working capital, capital expenditures, investments or 
acquisitions or other general corporate purposes;
•
increase our vulnerability to adverse changes in general economic, industry and competitive conditions;
•
place us at a disadvantage compared to other, less leveraged competitors;
•
expose us to the risk of increased borrowing costs and rising or high interest rates as a portion of our current 
borrowings under our 2022 Credit Facilities bear interest at variable rates (however, we have interest rate swaps 
that became effective on January 1, 2024, with an aggregate total notional amount of $150.0 million with a 
seven year tenor), which could further adversely impact our cash flows;
•
limit our flexibility to plan for and react to changes in our business and the industry in which we compete;
•
restrict us from making strategic acquisitions;
•
expose us to risk of unfavorable changes in the global credit markets; and
•
make it more difficult for us to satisfy our obligations with respect to the 2022 Credit Facilities and our other 
debt.
The occurrence of any one of these events could have an adverse effect on our business, financial condition, results of 
operations and ability to satisfy our obligations in respect of our outstanding debt.
We require a considerable amount of cash to run our business.
Our ability to make payments on our debt in the future and to fund planned capital expenditures and working capital needs, 
will depend upon our ability to generate significant cash in the future. Our ability to generate cash is subject to economic, 
financial, competitive, legislative, regulatory and other factors that may be beyond our control.
The terms of the 2022 Term Loan require us to make installment payments of 0.625% of the initial outstanding principal 
balance on a quarterly basis during years one and two, 1.250% during years three and four, and 1.875% during year five, on 
the last business day of each calendar quarter. In addition, the undrawn portion of the commitment of the 2022 Revolving 
Credit Facility is subject to a commitment fee ranging from 0.175% to 0.275%, based upon the consolidated total net adjusted 
leverage ratio. 
In April 2023, we acquired 100% of the outstanding equity interests of BLR for an initial purchase price of $115.0 million, 
net of cash acquired, all payable in cash. We paid a gross aggregate of $117.0 million in cash upon the closing of the 
transaction. We utilized the 2022 Revolving Credit Facility to complete the acquisition. See Note 2 to our consolidated 
financial statements included in Part IV, Item 15(a) of this Form 10-K for further discussion.
In July 2022, as a result of completing a refinancing of our existing debt, we were required to complete an amendment of all 
the forward interest rate swaps (“Amended Forward Interest Rate Swaps”) we entered into in November 2021 that were based 
Table of Contents
12
12

on U.S. dollar-one month London Interbank Offered Rate (“LIBOR”) to be based on one month Term Secured Overnight 
Financing Rate (“SOFR”) as borrowings can only be based on SOFR. The Amended Forward Interest Rate Swaps, with an 
aggregate total notional amount of $150.0 million and all with a seven year tenor, became effective on January 1, 2024. The 
weighted average fixed rate of the Amended Forward Interest Rate Swaps was 1.7%. At December 31, 2024, the outstanding 
balance on the 2022 Credit Facilities was $243.2 million with an average interest rate of 7.25%. Should interest rates increase 
significantly, our debt service cost on the variable portion of our debt will increase. Any inability to generate sufficient cash 
flow could have a material adverse effect on our financial condition or results of operations. See Note 1, Note 4, and Note 10 
to our consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K for further discussion.
While we expect to meet all of our financial obligations, we cannot ensure that our business will generate sufficient cash flow 
from operations in an amount sufficient to enable us to pay our debt or to fund our other liquidity needs.
We require a considerable amount of cash to fund our anticipated voluntary principal prepayments on our Credit 
Facilities.
Our ability to reduce the debt outstanding under our 2022 Credit Facilities through voluntary principal prepayments will be a 
contributing factor to our ability to keep our interest rate towards the lower end of the interest rate range as defined in the 
2022 Credit Facilities. Our ability to make such prepayments will depend upon our ability to generate significant cash in the 
future. We cannot ensure that our business will generate sufficient cash flow from operations to fund any such prepayments.
The covenants in our credit facilities impose restrictions that may limit our operating and financial flexibility.
We are required to comply with a leverage covenant as defined in the 2022 Credit Facilities. The leverage covenant is defined 
as Consolidated Funded Indebtedness less unrestricted cash and cash equivalents in excess of $5.0 million, divided by 
consolidated earnings before interest, taxes and depreciation and amortization (“EBITDA”) and other adjustments.
At December 31, 2024, we were in compliance with the leverage covenant under the 2022 Credit Facilities. However, there is 
no assurance that we will continue to be in compliance with the leverage covenant in future periods.
The 2022 Credit Facilities’ agreements contains a number of significant restrictions and covenants that limit our ability, 
among other things, to incur additional indebtedness, to create liens, to make certain payments, to make certain investments, 
to engage in transactions with affiliates, to sell certain assets or enter into mergers.
These covenants could materially and adversely affect our ability to finance our future operations or capital needs. 
Furthermore, they may restrict our ability to expand, pursue our business strategies and otherwise conduct our business. Our 
ability to comply with these covenants may be affected by circumstances and events beyond our control, such as prevailing 
economic conditions and changes in regulations, and we cannot ensure that we will be able to comply with such covenants. 
These restrictions also limit our ability to obtain future financings to withstand a future downturn in our business or the 
economy in general. 
A breach of any covenant in the 2022 Credit Facilities could result in a default under the 2022 Credit Facilities. A default, if 
not waived, could result in acceleration of the debt outstanding under the agreement. A default could permit our lenders to 
foreclose on any of our assets securing such debt. Even if new financing were available at that time, it may not be on terms or 
amounts that are acceptable to us or terms as favorable as our current agreements. If our debt is in default for any reason, our 
business, results of operations and financial condition could be materially and adversely affected.
The typical trading volume of our common stock may affect an investor’s ability to sell significant stock holdings in 
the future without negatively impacting stock price.
The level of trading activity may vary daily and typically represents only a small percentage of outstanding shares. As a 
result, a stockholder who sells a significant amount of shares in a short period of time could negatively affect our share price.
Our amount of debt may require us to raise additional capital to fund acquisitions.
We may sell additional shares of common stock or other equity securities to raise capital in the future, which could dilute the 
value of an investor’s holdings.

BUSINESS AND OPERATIONAL RISKS
Our end-use markets are cyclical.
We sell our products into aerospace, defense, and industrial end-use markets, which are cyclical and have experienced 
periodic declines. Our sales are, therefore, unpredictable and may tend to fluctuate based on a number of factors, including 
global economic conditions, U.S. defense budgetary spending, geopolitical developments and conditions, pandemics, supply 
chain shortages, rising or high interest rates and other developments affecting our end-use markets and the customers served. 
Consequently, results of operations in any period should not be considered indicative of the operating results that may be 
experienced in any future period.
We depend upon a select base of industries and customers, which subjects us to unique risks which may adversely 
affect us.
We currently generate the majority of our revenues from customers in the aerospace and defense industry. Our business 
depends, in part, on the level of new military and commercial aircraft orders. As a result, we have significant sales to certain 
customers. Sales to The Boeing Company (“Boeing”), Spirit AeroSystems Holdings, Inc. (“Spirit”), and Viasat, Inc. 
(“Viasat”) comprise a significant portion of our commercial aerospace end-use market in 2024. A significant portion of our 
net sales in our military and space end-use markets are made under subcontracts with original equipment manufacturers 
(“OEMs”), under their prime contracts with the U. S. Government. We had significant sales to Lockheed Martin Corporation 
(“Lockheed”), Northrop Grumman Corporation (“Northrop”), and RTX Corporation (f/k/a Raytheon Technologies 
Corporation) (“RTX”) in 2024 in our defense technologies end-use market.
Our customers may experience delays in the launch and certification of new products, labor strikes, diminished liquidity or 
credit unavailability, weak demand for their products, or other difficulties in their business. In addition, shifts in government 
spending priorities have caused and may continue to cause additional uncertainty in the placement of orders.
Our revenues from our top ten customers, which represented 60% of our total 2024 net revenues, were diversified over a 
number of different aerospace and defense products. Any significant change in production rates by these customers would 
have a material effect on our results of operations and cash flows. There is no assurance that our current significant customers 
will continue to buy products from us at current levels, or that we will retain any or all of our existing customers, or that we 
will be able to form new relationships with customers upon the loss of one or more of our existing customers. This risk may 
be further complicated by pricing pressures, competition prevalent in our industry and other factors. A significant reduction 
in sales to any of our major customers, the loss of a major customer, or a default of a major customer on accounts receivable 
could have a material adverse impact on our financial results.
Boeing was one of our largest customers in 2024, and the 737 MAX was one of our highest commercial end use market 
revenue platforms. In early January 2024, the FAA initiated an investigation into Boeing’s quality control system. This was 
followed by the FAA announcing actions to increase its oversight of Boeing as well as not approving production rate 
increases or additional production lines for the 737 MAX until it is satisfied that Boeing is in full compliance with required 
quality control procedures. In addition, in July 2024, Boeing also pleaded guilty to conspiracy fraud charges, which may 
result in additional external oversight on its manufacturing quality control process. Further, in September 2024, the 
International Association of Machinists and Aerospace Workers District 751 voted to initiate a labor strike affecting more 
than 30,000 Boeing manufacturing employees primarily located in Washington state, and the manufacturing employees, after 
rejecting the contract offer in October, voted to approve the revised contract offer in November 2024. Revenue growth with 
our other commercial customers, including Airbus SE (“Airbus”), and continued solid demand from defense OEMs (also 
known as prime contractors) have helped to mitigate a significant portion of this risk for the time being. However, the 
industry remains vulnerable to various developments including fuel spikes, inflationary forces, supply chain issues, and 
elevated high interest rates.
We generally make sales under purchase orders and contracts that are subject to cancellation, modification or rescheduling. 
Changes in the economic environment and the financial condition of the industries we serve could result in customer 
cancellation of contractual orders or requests for rescheduling. Some of our contracts have specific provisions relating to 
schedule and performance, and failure to deliver in accordance with such provisions could result in cancellations, 
modifications, rescheduling and/or penalties, in some cases at the customers’ convenience and without prior notice. While we 
have normally recovered our direct and indirect costs plus profit, such cancellations, modifications, or rescheduling that 
cannot be replaced in a timely fashion, could have a material adverse effect on our financial results.

A significant portion of our business depends upon U.S. Government defense spending.
We derive a significant portion of our business from customers whose principal sales are to the U.S. Government. 
Accordingly, the success of our business depends upon government spending generally or for specific departments or 
agencies in particular. Such spending, among other factors, is subject to the uncertainties of governmental appropriations and 
national defense policies and priorities, constraints of the budgetary process, timing and potential changes in these policies 
and priorities, and the adoption of new laws or regulations or changes to existing laws or regulations.
These and other factors could cause the government and government agencies, or prime contractors that use us as a 
subcontractor, to reduce their purchases under existing contracts, to exercise their rights to terminate contracts for 
convenience or to abstain from exercising options to renew contracts, any of which could have a material adverse effect on 
our business, financial condition and results of operations.
Further, the levels of U.S. Department of Defense (“U.S. DoD”) spending in future periods are difficult to predict and are 
impacted by numerous factors such as the political environment, U.S. foreign policy, macroeconomic conditions and the 
ability of the U.S. Government to enact relevant legislation such as the authorization and appropriations bills. For instance, on 
December 21, 2024, the U.S. government enacted a continuing resolution (“CR”) to keep the government funded through 
March 14, 2025 while the Congress works to enact full year fiscal year 2025 (“FY25”) appropriation bills or an additional CR 
to fund government departments and agencies after March 14, 2025. We, and a number of our customers rely on the U.S. 
government in various aspects of our defense and commercial businesses. In the event of a shutdown, requirements to 
furlough employees in the U.S. DoD or other government agencies could result in payment delays, impair our ability to 
perform work on existing contracts or otherwise impact our operations, negatively impact future orders, and/or cause other 
disruptions or delays.
The U.S. government could experience a disruption to its operations and/or payments in 2025 as a result of the U.S. Treasury 
exhausting extraordinary measures after reaching its debt limit. In addition, U.S. government discretionary spending in FY24 
and FY25, including defense spending, was capped by the Fiscal Responsibility Act of 2023 (“FRA23”). If a CR for FY25 is 
in place on April 30, 2025, it would trigger a sequester under the FRA23. These potential disruptions, and any other broader 
macroeconomic impacts, could affect our current programs and contracts and have a material effect on our financial position, 
results of operations and/or cash flows. 
Exports of certain of our products and our production facility in Guaymas, Mexico are subject to various export 
control regulations and authorizations, and we may not be successful in obtaining the necessary U.S. Government 
approvals and related export licenses for proposed sales to certain foreign customers.
We must comply with numerous laws and regulations relating to the export of some of our products before we are permitted 
to sell or manufacture those products outside the United States. Compliance often entails the submission and timely receipt of 
the necessary export approvals, licenses, or authorizations from the U.S. Government. Over the last several years, the U.S. 
export licensing environment for munitions has been adversely affected by a number of factors, including, but not limited to, 
the changing geopolitical environment and heightened tensions with other countries (which shift and evolve over time). 
Accordingly, we can give no assurance that we will be successful in obtaining, in a timely manner or at all, the approvals, 
licenses or authorizations we need to sell or manufacture our products outside the United States, which may result in the 
cancellation of orders and significant penalties to our customers if we do not make deliveries and fulfill our contractual 
commitments. Any significant delay in, or impairment of, our ability to sell products outside of the United States could have 
a material adverse effect on our business, financial condition and results of operations.
Contracts with some of our customers, including Federal government contracts, contain provisions which give our 
customers a variety of rights that are unfavorable to us and the OEMs to whom we provide products and services, 
including the ability to terminate a contract at any time for convenience.
Contracts with some of our customers, including Federal government contracts, contain provisions and are subject to laws 
and regulations that provide rights and remedies not typically found in commercial contracts. These provisions may allow our 
customers to:
•
terminate existing contracts, in whole or in part, for convenience, as well as for default, or if funds for contract 
performance for any subsequent year become unavailable;
•
terminate existing contracts if we are suspended or debarred from doing business with the federal government 
or with a governmental agency;
Table of Contents

•
prohibit future procurement awards with a particular agency as a result of a finding of an organizational conflict 
of interest based upon prior related work performed for the agency that would give a contractor an unfair 
advantage over competing contractors; and
•
claim rights in products and systems produced by us.
If the U.S. Government terminates a contract for convenience, the counterparty with whom we have contracted on a 
subcontract may terminate its contract with us. As a result of any such termination, whether on a direct government contract 
or subcontract, we may recover only our incurred or committed costs, settlement expenses and profit on work completed prior 
to the termination. If the U.S. Government terminates a direct contract with us for default, we may not even recover those 
amounts and instead may be liable for excess costs incurred by the U.S. Government in procuring undelivered items and 
services from another source.
In addition, the U.S. Government is typically required to open all programs to competitive bidding and, therefore, may not 
automatically renew any of its prime contracts. If one or more of our customers’ government prime or subcontracts is 
terminated or canceled, our failure to replace sales generated from such contracts would result in lower sales and could have 
an adverse effect on our business, results of operations and financial condition.
Further consolidation in the aerospace industry could adversely affect our business and financial results.
The aerospace and defense industry has and continues to experience significant consolidation, including our customers, 
competitors and suppliers. Consolidation among our customers may result in delays in the awarding of new contracts and 
losses of existing business. Consolidation among our competitors may result in larger competitors with greater resources and 
market share, which could adversely affect our ability to compete successfully. Consolidation among our suppliers may result 
in fewer sources of supply and increased cost to us.
Our growth strategy includes evaluating selected acquisitions, which entails certain risks to our business and financial 
performance. 
We have historically achieved a portion of our growth through acquisitions and expect to evaluate selected future acquisitions 
as part of our strategy for growth. Any acquisition of another business entails risks and it is possible that we may not realize 
the expected benefits from an acquisition or that an acquisition could adversely affect our existing operations. Acquisitions 
entail certain risks, including:
•
difficulty in integrating the operations and personnel of the acquired company within our existing operations or 
in maintaining uniform standards;
•
loss of key employees or customers of the acquired company; 
•
the failure to achieve anticipated synergies;
•
unrecorded liabilities of acquired companies that we fail to discover during our due diligence investigations or 
that are not subject to indemnification or reimbursement by the seller; and 
•
management and other personnel having their time and resources diverted to evaluate, negotiate and integrate 
acquisitions. 
We may not be successful in achieving expected operating efficiencies and sustaining or improving operating expense 
reductions, and may experience business disruptions associated with restructuring, performance center 
consolidations, realignment, cost reduction, and other strategic initiatives.
In recent years, we have implemented a number of restructuring, realignment, and cost reduction initiatives, including 
performance center consolidations, organizational realignments, and reductions in our workforce. While we have realized 
some efficiencies from these actions, we may not realize the benefits of these initiatives to the extent we anticipated. Further, 
such benefits may be realized later than expected, and the ongoing difficulties in implementing these measures may be 
greater than anticipated, which could cause us to incur additional costs or result in business disruptions. In addition, if these 
measures are not successful or sustainable, we may have to undertake additional realignment and cost reduction efforts, 
which could result in significant additional charges. Moreover, if our restructuring and realignment efforts prove ineffective, 
our ability to achieve our other strategic and business plan goals may be adversely impacted.

As we move up the value chain to become a more value added supplier, enhanced design, product development, 
manufacturing, supply chain project management and other skills will be required.
We may encounter difficulties as we execute our growth strategy to move up the value chain to become a more value added 
supplier of more complex assemblies. Difficulties we may encounter include, but are not limited to, the need for enhanced 
and expanded product design skills, enhanced ability to control and influence our suppliers, enhanced quality control systems 
and infrastructure, enhanced large-scale project management skills, and expanded industry certifications. Assuming 
incremental project design responsibilities would require us to assume additional risk in developing cost estimates and could 
expose us to increased risk of losses. There can be no assurance that we will be successful in obtaining the enhanced skills 
required to move up the value chain or that our customers will outsource such functions to us.
Risks associated with operating and conducting our business outside the United States could adversely impact us.
We have a manufacturing facility that we lease in Mexico and also derive a portion of our net revenues from direct foreign 
sales. Further, our customers may derive portions of their revenues from non-U.S. customers. As a result, we are subject to 
the risks of conducting and operating our business internationally, including:
•
political instability that may result in price fluctuations of raw materials;
•
economic and geopolitical developments and conditions;
•
pandemics and disasters, natural or otherwise;
•
compliance with a variety of international laws, as well as U.S. laws affecting the activities of U.S. companies 
conducting business abroad, including, but not limited to, the Foreign Corrupt Practices Act;
•
imposition of taxes, export control approvals or licenses, tariffs, embargoes and other trade restrictions;
•
difficulties repatriating funds or restrictions on cash transfers; and
•
potential for new tariffs imposed on imports by the U.S. administration that may affect our ability to import raw 
materials into the U.S. and finished goods from our leased manufacturing facility in Mexico and increase the 
cost of such imports.
While the impact of these factors is difficult to predict, we believe any one or more of these factors could have a material 
adverse effect on our financial results.
Customer pricing pressures could reduce the demand and/or price for our products and services.
The markets we serve are highly competitive and price sensitive. We compete worldwide with a number of domestic and 
international companies that have substantially greater manufacturing, purchasing, marketing and financial resources than we 
do. Many of our customers have the in-house capability to fulfill their manufacturing requirements. Our larger competitors 
may be able to compete more effectively for very large-scale contracts than we can by providing different or greater 
capabilities or benefits such as technical qualifications, past performance on large-scale contracts, geographic presence, price 
and availability of key professional personnel. If we are unable to successfully compete for new business, our net revenues 
growth and operating margins may decline.
Some of our major customers have completed extensive cost containment efforts and we expect continued pricing pressures 
in 2025 and beyond. Competitive pricing pressures may have an adverse effect on our financial condition and operating 
results. Further, there can be no assurance that competition from existing or potential competitors in other segments of our 
business will not have a material adverse effect on our financial results. If we do not continue to compete effectively and win 
contracts, our future business, financial condition, results of operations and our ability to meet our financial obligations may 
be materially compromised.
Our products and processes are subject to risk of obsolescence as a result of changes in technology and evolving 
industry and regulatory standards.
The future success of our business depends in large part upon our and our customers’ ability to maintain and enhance 
technological capabilities, develop and market manufacturing services that meet changing customer needs and successfully 
anticipate or respond to technological advances in manufacturing processes such as the incorporation of artificial intelligence 
and other disruptive technologies on a cost-effective and timely basis, while meeting evolving industry and regulatory 
standards. To address these risks, we invest in product design and development, and incur related capital expenditures. There 
Table of Contents
17
17

can be no guarantee that our product design and development efforts will be successful, or that funds required to be invested 
in product design and development or incurred as capital expenditures will not increase materially in the future.
We may not have the ability to renew facilities leases on terms favorable to us and relocation of operations presents 
risks due to business interruption.
Certain of our manufacturing facilities and offices are leased and have lease terms that expire between 2025 and 2034. The 
majority of these leases provide renewal options at the fair market rental rate at the time of renewal, which, if renewed, could 
be significantly higher than our current rental rates. We may be unable to offset these cost increases by charging more for our 
products and services. Furthermore, continued economic conditions may continue to negatively impact and create greater 
pressure in the commercial real estate market, causing higher incidences of landlord default and/or lender foreclosure of 
properties, including properties occupied by us. While we maintain certain non-disturbance rights in most cases, it is not 
certain that such rights will in all cases be upheld and our continued right of occupancy in such instances could be potentially 
jeopardized. An occurrence of any of these events could have a material adverse effect on our financial results.
Additionally, if we choose to move any of our operations, those operations may be subject to additional relocation costs and 
associated risks of business interruption.
LEGAL, REGULATORY, TAX, AND ACCOUNTING RISKS
We are subject to extensive regulation and audit by the Defense Contract Audit Agency.
The accuracy and appropriateness of certain costs and expenses used to substantiate our direct and indirect costs for the U.S. 
Government contracts are subject to extensive regulation and audit by the Defense Contract Audit Agency, an arm of the U.S. 
DoD. Such audits and reviews could result in adjustments to our contract costs and profitability. However, we cannot ensure 
the outcome of any future audits and adjustments may be required to reduce net sales or profits upon completion and final 
negotiation of audits. If any audit or review were to uncover inaccurate costs or improper activities, we could be subject to 
penalties and sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension 
or prohibition from conducting future business with the U.S. Government. Any such outcome could have a material adverse 
effect on our financial results.
We are subject to a number of procurement laws and regulations. Our business and our reputation could be adversely 
affected if we fail to comply with these laws.
We must comply with and are affected by laws and regulations relating to the award, administration and performance of U.S. 
Government contracts. Government contract laws and regulations affect how we do business with our customers and impose 
certain risks and costs on our business. A violation of specific laws and regulations, by us, our employees, or others working 
on our behalf, such as a supplier or a venture partner, could harm our reputation and result in the imposition of fines and 
penalties, the termination of our contracts, suspension or debarment from bidding on or being awarded contracts, loss of our 
ability to export products or services and civil or criminal investigations or proceedings. 
In some instances, these laws and regulations impose terms or rights that are different from those typically found in 
commercial transactions. For example, the U.S. Government may terminate any of our customers’ government contracts and 
subcontracts either at its convenience or for default based on our performance. Upon termination for convenience of a fixed-
price type contract, we normally are entitled to receive the purchase price for delivered items, reimbursement for allowable 
costs for work-in-process and an allowance for profit on the contract or adjustment for loss if completion of performance 
would have resulted in a loss.
Our operations are subject to numerous extensive, complex, costly and evolving laws, regulations and restrictions, 
including cybersecurity requirements, and failure to comply with these laws, regulations and restrictions could 
subject us to penalties and sanctions that could harm our business.
Prime contracts with our major customers that have contracts with various agencies of the U.S. Government are subject to 
numerous laws, regulations and certifications, which affect how we do business with our customers and may impose added 
costs to our business. As a result, our contracts and operations are subject to numerous extensive, complex, costly and 
evolving laws, regulations and restrictions, principally by the U.S. Government or their agencies. These laws, regulations and 
restrictions govern items including, but not limited to, the formation, administration and performance of U.S. Government 
contracts, disclosure of cost and pricing data, civil penalties for violations of false claims to the U.S. Government for 
payment, defining reimbursable costs, establishing ethical standards for the procurement process, controlling the import and

export of defense articles and services, and cybersecurity requirements, such as Cybersecurity Maturity Model Certification 
(“CMMC”).
Noncompliance could expose us to liability for penalties, including termination of our contracts and subcontracts, 
disqualification from bidding on future U.S. Government contracts and subcontracts, suspension or debarment from U.S. 
Government contracting and various other fines and penalties. Noncompliance found by any one agency could result in fines, 
penalties, debarment or suspension from receiving additional contracts with all U.S. Government agencies. Given our 
dependence on U.S. Government business, suspension or debarment could have a material adverse effect on our financial 
results.
In addition, the U.S. Government may revise its procurement practices or adopt new contract rules and regulations at any 
time, including increased usage of fixed-price contracts, procurement reform, and compliance with cybersecurity 
requirements. Such changes could impair our ability to obtain new contracts or subcontracts or renew contracts or 
subcontracts under which we currently perform when those contracts are put up for competitive bidding. Any new contracting 
methods could be costly or administratively difficult for us to implement and could adversely affect our future net revenues.
In addition, our international operations subject us to numerous U.S. and foreign laws and regulations, including, without 
limitation, regulations relating to import-export control, technology transfer restrictions, repatriation of earnings, exchange 
controls, the Foreign Corrupt Practices Act and other similar antibribery laws, and the anti-boycott provisions of the U.S. 
Export Administration Act. Changes in regulations or political environments may affect our ability to conduct business in 
foreign markets including investment, procurement and repatriation of earnings. Failure by us or our sales representatives or 
consultants to comply with these laws and regulations could result in certain liabilities and could possibly result in suspension 
or debarment from government contracts or suspension of our export privileges, which could have a material adverse effect 
on our financial results.
Environmental liabilities could adversely affect our financial results.
We are subject to various federal, local, and foreign environmental laws and regulations, including those relating to the use, 
storage, transport, discharge and disposal of hazardous and non-hazardous chemicals and materials used and emissions 
generated during our manufacturing process. We do not carry insurance for these potential environmental liabilities. Any 
failure by us to comply with present or future regulations could subject us to future liabilities or the suspension of production, 
which could have a material adverse effect on our financial results. Moreover, some environmental laws relating to 
contaminated sites can impose joint and several liability retroactively regardless of fault or the legality of the activities giving 
rise to the contamination. Compliance with existing or future environmental laws and regulations may require extensive 
capital expenditures, increase our cost or impact our production capabilities. Even if such expenditures are made, there can be 
no assurance that we will be able to comply. We have been directed to investigate and take corrective action for groundwater 
contamination at certain sites and our ultimate liability for such matters will depend upon a number of factors. See Note 16 to 
our consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K for further information.
We may be subject to litigation, other legal proceedings and indemnity claims, and, if any of these are resolved 
adversely against us in amounts that exceed the limits of our insurance coverage, it could have a material adverse 
effect on our business, financial condition, and results of operations.
From time to time, we and our subsidiaries are involved in various legal and other proceedings that are incidental to the 
conduct of our business. Any litigation, other legal proceedings or indemnity claims could result in an unfavorable judgment 
that may not be reversed upon appeal or in payments of substantial monetary damages or fines that may exceed our insurance 
coverage limits, or we may decide to settle on similarly unfavorable terms, any of which could adversely affect our business, 
financial condition, and results of operations. We could also suffer an adverse impact on our reputation and a diversion of 
management’s attention and resources, which could have a material adverse effect on our business, financial condition, and 
results of operations. See Note 14 and Note 16 to our consolidated financial statements included in Part IV, Item 15(a) of this 
Form 10-K for further information.
Product liability claims in excess of insurance could adversely affect our financial results and financial condition.
We face potential liability for property damage, personal injury, or death as a result of the failure of products designed or 
manufactured by us. Although we currently maintain product liability insurance (including aircraft product liability 
insurance), any material product liability not covered by insurance could have a material adverse effect on our financial 
condition, results of operations and cash flows.

We use estimates when bidding on fixed-price contracts. Changes in our estimates could adversely affect our financial 
results.
We enter into contracts providing for a firm, fixed-price for the sale of a majority of our products, regardless of the 
production costs incurred by us. In many cases, we make multi-year firm, fixed-price commitments to our customers, without 
assurance that our anticipated production costs will be achieved. Contract bidding and accounting require judgment relative 
to assessing risks, estimating contract net sales and costs, including estimating cost increases over time and efficiencies to be 
gained, and making assumptions for supplier sourcing and quality, manufacturing scheduling and technical issues over the 
life of the contract. Such assumptions can be particularly difficult to estimate for contracts with new customers. Inaccurate 
estimates of these costs could result in reduced profits or incurred losses. Due to the significance of the judgments and 
estimates involved, it is possible that materially different amounts could be obtained if different assumptions were used or if 
the underlying circumstances were to change. Therefore, any changes in our underlying assumptions, circumstances or 
estimates could have a material adverse effect on our financial results. 
Goodwill and/or other assets could be impaired in the future, which could result in substantial charges.
Goodwill is tested for impairment on an annual basis as of the first day of our fiscal fourth quarter or more frequently if 
events or circumstances occur which could indicate potential impairment. In assessing the recoverability of goodwill, 
management is required to make certain critical estimates and assumptions. These estimates and assumptions include 
projected sales levels, including the addition of new customers, programs or platforms and increased content on existing 
programs or platforms, improvements in manufacturing efficiency, and reductions in operating costs. Due to many variables 
inherent in the estimation of a business’s fair value and the relative size of our recorded goodwill, changes in estimates and 
assumptions may have a material effect on the results of our impairment analysis. If any of these or other estimates and 
assumptions are not realized in the future, or if market multiples decline, we may be required to record an impairment charge 
for goodwill. 
We also test intangible assets with indefinite life periods for potential impairment annually and on an interim basis if there are 
indicators of potential impairment. 
In addition, we evaluate amortizable intangible assets, fixed assets, production cost of contracts, and lease right-of-use assets 
for impairment if there are indicators of a potential impairment. 
Further, impairment charges may be incurred against other intangible assets or long-term assets if asset utilization declines, 
customer demand declines or other circumstances indicate that the asset carrying value may not be recoverable. 
Our goodwill and other intangible assets as of December 31, 2024 were $394.2 million, or 35% of total assets. If our 
goodwill and/or other assets are impaired, it could have an adverse effect on our results of operations and financial condition. 
See “Goodwill and Other Intangible Assets” in Note 8 of our consolidated financial statements included in Part IV, 
Item 15(a) of this Form 10-K for further information.
We expect to face increased costs and resources needed to comply with the SEC cybersecurity rule and cybersecurity 
threats.
The SEC adopted a rule, “Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure,” that enhances 
and standardizes disclosures regarding cybersecurity risk management and governance, as well as material cybersecurity 
incidents. Under this rule, public companies are required to make annual disclosures describing their processes for identifying 
and managing material cybersecurity risks, management’s role in assessing and managing such risks, and the Board of 
Directors’ oversight of cybersecurity risks. Companies also must disclose in a Form 8-K, the nature, scope, and timing of any 
material cybersecurity incidents identified and the material impact or reasonably likely material impact on the company 
within four business days of determining a cybersecurity incident is material. We expect to face increased costs to comply 
with this SEC cybersecurity rule, including increased costs for cybersecurity training, staffing, and management. In addition, 
the requirement to report cybersecurity incidents within such a short timeframe could mean there may not be sufficient time 
to halt a breach before having to report it, potentially giving the hackers an advantage.
Unanticipated changes in our tax provision or exposure to additional income tax liabilities could affect our 
profitability.
Significant judgment is required in determining our provision for income taxes. In the ordinary course of our business, there 
are transactions and calculations where the ultimate tax determination is uncertain. Furthermore, changes in income tax laws 
Table of Contents
20
20

and regulations, or their interpretation, could result in higher or lower income tax rates assessed or changes in the taxability of 
certain sales or the deductibility of certain expenses, thereby affecting our income tax expense and profitability. In addition, 
we are regularly under audit by tax authorities. The final determination of tax audits and any related litigation could be 
materially different from our historical income tax provisions and accruals.
Management has identified a material weakness in the past in our internal control over financial reporting which 
could, if not remediated, adversely impact the reliability of our financial reports, cause us to submit our financial 
reports in an untimely fashion, result in material misstatements in our financial statements and cause current and 
potential stockholders to lose confidence in our financial reporting, which in turn could adversely affect the trading 
price of our stock.
In our 2023 Form 10-K, we concluded there was a material weakness in our internal control over financial reporting as of 
December 31, 2023, as we did not design and maintain effective controls over the accuracy of contract terms and the 
reasonableness of gross margin assumptions used to recognize revenue. Specifically, we did not verify that amendments to 
purchase orders and gross margin percentage assumptions used in our revenue recognition analysis were properly reviewed at 
a sufficient level of precision. The material weakness resulted in immaterial adjustments to net revenues and contract assets 
as of and for the quarterly and annual periods ending December 31, 2023. Thus, management determined that our disclosure 
controls and procedures and internal control over financial reporting were not effective as of December 31, 2023. This 
material weakness was remediated as of December 31, 2024.
Under standards established by the Public Company Accounting Oversight Board (“PCAOB”), a material weakness is a 
deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable 
possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected and 
corrected on a timely basis. 
When a material weakness occurs, we plan to complete the remediation process as quickly as possible. If our remedial 
measures are insufficient to address the material weakness, or if additional material weaknesses or significant deficiencies in 
our internal control over financial reporting are discovered or occur in the future, our consolidated financial statements may 
contain material misstatements and we could be required to restate our financial results. In addition, if we are unable to 
successfully remediate a material weakness and if we are unable to produce accurate and timely financial statements, our 
stock price may be adversely affected and we may be unable to maintain compliance with applicable stock exchange listing 
requirements and debt covenant requirements.
Our ability to accurately report our financial results or prevent fraud may be adversely affected if our internal 
control over financial reporting is not effective.
The accuracy of our financial reporting is dependent on the effectiveness of our internal controls. We are required to provide 
a report from management to our shareholders on our internal control over financial reporting that includes an assessment of 
the effectiveness of these controls. Internal control over financial reporting has inherent limitations, including human error, 
the possibility that controls could be circumvented or become inadequate as a result of changed conditions, and fraud. Due to 
these inherent limitations, internal control over financial reporting might not prevent or detect all misstatements or fraud. If 
we cannot maintain and execute adequate internal control over financial reporting or implement required new or improved 
controls that provide reasonable assurance of the reliability of the financial reporting and preparation of our financial 
statements for external use, our ability to accurately report our financial results or prevent fraud could be adversely affected.
LABOR AND SUPPLY CHAIN RISKS
We are dependent upon our ability to attract and retain key personnel.
Our success depends in part upon our ability to attract and retain key engineering, technical and managerial personnel, at both 
the executive and performance center level. We face competition for management, engineering and technical personnel from 
other companies and organizations. The loss of members of our senior management group, or key engineering and technical 
personnel, could negatively impact our ability to grow and remain competitive in the future and could have a material adverse 
effect on our financial results.
Table of Contents

21

Labor disruptions by our employees could adversely affect our business.
As of December 31, 2024, we employed 2,180 people. One of our performance centers is party to a collective bargaining 
agreement, covering 268 full time hourly employees, which will expire in April 2025. Although we have not experienced any 
material labor-related work stoppage and consider our relations with our employees to be good, labor stoppages may occur in 
the future. If the unionized workers were to engage in a strike or other work stoppage, if we are unable to negotiate 
acceptable collective bargaining agreements with the unions or if other employees were to become unionized, we could 
experience a significant disruption of our operations, higher ongoing labor costs and possible loss of customer contracts, 
which could have an adverse effect on our business and results of operations.
We rely on our suppliers to meet the quality and delivery expectations of our customers.
Our ability to deliver our products and services on schedule and to satisfy specific quality levels is dependent upon a variety 
of factors, including execution of internal performance plans, availability of raw materials, internal and supplier produced 
parts and structures, conversion of raw materials into parts and assemblies, and performance of suppliers and others.
We rely on numerous third-party suppliers for raw materials and a large proportion of the components used in our production 
process. Certain of these raw materials and components are available only from single sources or a limited number of 
suppliers, or similarly, customers’ specifications may require us to obtain raw materials and/or components from a single 
source or certain suppliers. Many of our suppliers are small companies with limited financial resources and manufacturing 
capabilities. We do not currently have the ability to manufacture these components ourselves. These and other factors, 
including the impact from import tariffs, the loss of a critical supplier or raw materials and/or component shortages, could 
cause disruptions or cost inefficiencies in our operations. Additionally, our competitors that have greater direct purchasing 
power, may have product cost advantages which could have a material adverse effect on our financial results.
GENERAL RISKS
Cybersecurity attacks, internal system or service failures may adversely impact our business and operations.
Any system or service disruptions, including those caused by projects to improve our information technology systems, if not 
anticipated and appropriately mitigated, could disrupt our business and impair our ability to effectively provide products and 
related services to our customers and could have a material adverse effect on our business. Like other public companies, our 
computer systems and those of our third party vendors and service providers are regularly subject to, and will continue to be 
the target of systems failures, including network, software or hardware failures, whether caused by us, third-party service 
providers, intruders or hackers, computer viruses, natural disasters, power shortages or terrorist attacks. Cybersecurity threats 
are evolving and include, but are not limited to, malicious software, unauthorized attempts to gain access to sensitive, 
confidential or otherwise protected information related to us or our products, our employees, customers or suppliers, or other 
acts that could lead to disruptions in our business, which risk may be heightened by the increased prevalence and use of 
artificial intelligence. Any such failures could cause loss of data and interruptions or delays in our business, cause us to incur 
remediation costs, subject us to claims and damage our reputation. In addition, such cybersecurity attacks may result in a 
significant ransom demand. Further, the failure or disruption of our communications or utilities could cause us to interrupt or 
suspend our operations or otherwise adversely affect our business. Our property and business interruption insurance may be 
inadequate to compensate us for all losses that may occur as a result of any system or operational failure or disruption which 
would adversely affect our business, results of operations and financial condition.
We may be unable to adequately protect or enforce our intellectual property rights.
Our intellectual property rights may not be sufficiently broad or otherwise may not provide us a significant competitive 
advantage, and patents may not be issued for pending or future patent applications owned by or licensed to us. As patents 
expire, we could face increased competition, which could negatively impact our operating results. Infringement of our 
intellectual property and other proprietary rights by a third party, or copying of our technology in countries where we do not 
hold patents, could result in uncompensated lost market and revenue opportunities. We cannot be certain that the measures 
we have implemented will prevent our intellectual property from being improperly disclosed, challenged, invalidated, or 
circumvented, particularly in countries where intellectual property rights are not highly developed or protected. For example, 
competitors may avoid infringement liability by developing non-infringing competing technologies or by effectively 
concealing infringement. We may need to spend significant resources monitoring and enforcing our intellectual property 
rights, and we may not be aware of or able to detect or prove infringement by third parties. Our ability to enforce our 
intellectual property rights is subject to litigation risks, as well as uncertainty as to the protection and enforceability of those 
Table of Contents
22
22

rights in some countries. If we seek to enforce our intellectual property rights, we may be subject to claims that those rights 
are invalid or unenforceable, and others may seek counterclaims against us, which could have a negative impact on our 
business. In addition, changes in intellectual property laws or their interpretation may impact our ability to protect and assert 
our intellectual property rights, increase costs and uncertainties in the prosecution of patent applications and enforcement or 
defense of issued patents, and diminish the value of our intellectual property. If we do not protect and enforce our intellectual 
property rights successfully, or if they are circumvented, invalidated, or rendered obsolete by the rapid pace of technological 
change, it could have an adverse impact on our competitive position and our operating results.
Assertions by third parties that we violated their intellectual property rights could have a material adverse effect on 
our business, financial condition, and results of operations.
Third parties may claim that we, our customers, licensees, or parties indemnified by us are infringing upon or otherwise 
violating their intellectual property rights. Such claims may be made by competitors seeking to obtain a competitive 
advantage or by other parties. Additionally, in recent years, individuals and groups have begun purchasing intellectual 
property assets for the purpose of making claims of infringement and attempting to extract settlements from companies like 
ours.
Any claims that we violated a third party’s intellectual property rights can be time consuming and costly to defend and 
distract management’s attention and resources, even if the claims are without merit. Such claims may also require us to 
redesign affected products and services, enter into costly settlement or license agreements or pay costly damage awards, or 
face a temporary or permanent injunction prohibiting us from marketing or providing the affected products and services. 
Even if we have an agreement to indemnify us against such costs, the indemnifying party may not have sufficient financial 
resources or otherwise be unable to uphold its contractual obligations. If we cannot or do not license the infringed technology 
on favorable terms or cannot or do not substitute similar technology from another source, our revenue and earnings could be 
adversely impacted.
Damage or destruction of our facilities caused by storms, earthquake, fires or other causes could adversely affect our 
financial results and financial condition.
We have operations located in regions of the U.S. and Mexico that may be exposed to damaging storms, earthquakes, fires 
and other natural disasters. Although we maintain standard property casualty insurance covering our properties and may be 
able to recover costs associated with certain natural disasters through insurance, we do not carry any earthquake insurance 
because of the cost of such insurance. Many of our properties are located in Southern California, an area subject to 
earthquake activity. Our California performance centers generated $184.0 million in net revenues during 2024. Even if 
covered by insurance, any significant damage or destruction of our facilities due to storms, earthquakes, fires or other natural 
disasters could result in our inability to meet customer delivery schedules and may result in the loss of customers and 
significant additional costs to us. Thus, any significant damage or destruction of our properties could have a material adverse 
effect on our business, financial condition or results of operations. See discussion of a fire in June 2020 which severely 
damaged our Guaymas, Mexico performance center in Note 16 to our consolidated financial statements included in Part IV, 
Item 15(a) of this Form 10-K for further information.

We have an enterprise-wide approach to addressing cybersecurity risk, including input and participation from management 
and support from our Information Technology (“IT”) Steering Committee that is comprised of our Senior Vice President 
Electronic and Structural Systems, Chief Financial Officer, General Counsel, Chief Human Resources Officer, Vice President 
Supply Chain Management, and Chief Information Security Officer (Head of IT and Cybersecurity or “CISO”). Our 
cybersecurity risk management program leverages the National Institute of Standards and Technology (“NIST”) Framework 
which is augmented with Cybersecurity Maturity Model Certification (“CMMC”) components to meet our particular needs. 
We regularly assess the threat landscape and take a holistic view of the cybersecurity risks, with a layered cybersecurity 
strategy based on protection, detection, and mitigation. Our IT security team, which is comprised of internal resources, 
reviews enterprise risk management-level cybersecurity risks at least annually. 
Our CISO is responsible for developing, implementing, and maintaining our information security strategy and program, as 
well as reporting various cybersecurity risk matters to our IT Steering Committee, and the Board’s Innovation Committee.

The Innovations Committee is a subset of the full Board of Directors which receive regular updates on our cybersecurity 
program. 
Our CISO has over 18 years of experience leading cybersecurity oversight for several companies and is updated on cyber 
events related to the monitoring, prevention, detection, mitigation, and remediation efforts from our IT security team. The IT 
security team have broad cybersecurity expertise or industry certifications and are knowledgeable in the use of cybersecurity 
tools and software. In addition, third-party cybersecurity services are used to augment our in-house capabilities, as needed. 
We continue to expand investments in IT security, including additional end-user security awareness training, using layered 
defenses, identifying and protecting critical systems, strengthening monitoring and alerting, and engaging experts as needed. 
We also use an industry standard risk quantification model to identify, measure, and prioritize cybersecurity risks. This in 
turn, helps us develop and implement effective security controls and technology defenses. In addition, all employees are 
required to complete various cybersecurity awareness trainings on a regular basis. Further, we perform periodic simulations 
and tabletop exercises with the IT security team and will continue to expand its participants as appropriate. Our assessment of 
risks associated with the use of third party providers is on a limited basis and is part of our current overall cybersecurity risk 
management approach. As the threats and attacks are becoming more sophisticated, we will modify and enhance our 
cybersecurity program as needed.
As a defense contractor, we must also comply with extensive regulations, including requirements imposed by the Defense 
Federal Acquisition Regulation Supplement (“DFARS”) related to adequately safeguarding controlled unclassified 
information (“CUI”). The Department of Defense (“DoD”) will require defense contractors to comply with its CMMC 
program in the near future. We are incorporating the requirements of the CMMC program into our overall cybersecurity 
program and anticipate we will be in position to meet such requirements by the time it becomes fully rolled out in 2028.
To date, we do not believe risks from cybersecurity threats, including as a result of any previous cybersecurity incidents have 
materially affected us or are reasonably likely to materiality affect us, including our business strategy, results of operations or 
financial condition. See “Cybersecurity attacks, internal system or service failures may adversely impact our business and 
operations” in Risk Factors included in Part I, Item 1A of this Form 10-K. Such incidents, whether or not successful, could 
result in our incurring significant costs related to, for example, rebuilding our internal systems, implementing additional 
threat protection measures, defending against litigation, responding to regulatory inquiries or actions, paying damages, 
providing customers with incentives to maintain a business relationship with us, or taking other remedial steps with third-
parties, as well as incurring significant reputational harm. In addition, these threats are constantly evolving, thereby 
increasing the difficulty of successfully defending against them or implementing adequate preventive measures. For more 
information regarding the risks we face from cybersecurity threats, please see “Cybersecurity attacks, internal system or 
service failures may adversely impact our business and operations” in Risk Factors included in Part I, Item 1A of this Form 
10-K.
ITEM 2. PROPERTIES 
Our headquarters are located in Costa Mesa, California. As of December 31, 2024, we owned or leased facilities and land for 
corporate functions and manufacturing at locations throughout the United States and a manufacturing location outside the 
United States. We believe our existing facilities are suitable and adequate for our present purposes. Each of our reportable 
segments uses each of these facilities.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS
Overview
Ducommun Incorporated (“Ducommun,” “the Company,” “we,” “us” or “our”) is a leading global provider of engineering 
and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the 
aerospace and defense (“A&D”), industrial, medical, and other industries (“Industrial”). We differentiate ourselves as a full-
service solution-based provider, offering a wide range of value-added products and services in our primary businesses of 
electronics, structures and integrated solutions. We operate through two primary business segments:  Electronic Systems and 
Structural Systems, each of which is a reportable segment.
In its 2024 Annual Report on Form 10-K, The Boeing Company (“Boeing”) indicated that in 2024, global air traffic continue 
to expand beyond 2019 levels with domestic travel continuing to be the most robust and the single-aisle market following 
closely. International travel also surpassed pre-pandemic levels during 2024 and the wide-body market continues to improve 
with the international travel recovery. The transition in the international commercial market from recovery to normal market 
conditions is continuing to progress as China international travel remain below 2019 levels. For 2025, while both major large 
aircraft manufacturers, Boeing and Airbus SE, expect increases in build rates compared to 2024, the ramp up to date has been 
slower than initially expected and below pre-pandemic levels. In addition, Boeing, one of our largest customers, was notified 
by the Federal Aviation Administration (“FAA”) in early January 2024 that the FAA had initiated an investigation into 
Boeing’s quality control system. This notification was followed by the FAA announcing actions to increase its oversight of 
Boeing as well as not approving production rate increases or additional production lines for the 737 MAX until it is satisfied 
that Boeing is in full compliance with required quality control procedures. In July 2024, Boeing also pleaded guilty to 
conspiracy fraud charges, which may result in additional external oversight on its manufacturing and quality control process. 
Further, in September 2024, the International Association of Machinists and Aerospace Workers District 751 voted to initiate 
a labor strike affecting more than 30,000 Boeing manufacturing employees primarily located in Washington state, and the 
manufacturing employees, after rejecting the contract offer in October, voted to approve the revised contract offer in 
November 2024. Since Boeing is one of our largest customers, if Boeing is unable to meet the full compliance of the FAA’s 
required quality control procedures, and/or recover from the impact of the labor strike in the near term, it could have a 
material adverse impact on our business, results of operations and financial condition. See Risk Factors included in Part I, 
Item 1A of this Annual Report on Form 10-K (“Form 10-K”).

Net revenues for 2024 were $786.6 million compared to $757.0 million for 2023. The year-over-year increase was primarily 
due to the following:
•
$23.8 million higher revenues in our commercial aerospace end-use markets due to growth in Airbus, higher 
rates on rotary-wing aircraft and growth in business jet platforms, partially offset by lower revenues from in-
flight entertainment; and
•
$16.1 million higher revenues in our military and space end-use markets due to higher rates on selected missile, 
electronic warfare, radar, and naval and submarine platforms, partially offset by lower rates on selected fixed-
wing aircraft platforms.
In addition, revenues for our industrial end-use markets for 2024 decreased $10.4 million compared to 2023 mainly due to 
our selectively pruning non-core business.
Net Revenues by Major Customers
A significant portion of our net revenues are from our top ten customers as follows:

(“Spirit”), and Viasat, Inc. (“Viasat”).
The revenues from Boeing, Lockheed, Northrop, RTX, Spirit, and Viasat are diversified over a number of commercial, 
military and space programs and some of which were generated by both operating segments.
Gross Profit
Gross profit consists of net revenues less cost of sales. Cost of sales includes the cost of production of finished products and 
other expenses related to inventory management, manufacturing quality, and order fulfillment. Gross profit margin increased 
to 25.1% in 2024 compared to 21.6% in 2023. The increase in gross margin percentage year-over-year was primarily due to a 
higher mix of engineered products, strategic value pricing actions and the benefits of the restructuring plan.
Selling, General and Administrative (“SG&A”) Expenses
SG&A expenses increased $18.9 million in 2024 compared to 2023 primarily due to BLR SG&A expenses of $4.7 million 
which did not exist for the full year in the prior year period, higher professional services fees of $6.3 million, of which $3.1 
million was related to the unsolicited non-binding offer to acquire all the common stock outstanding of Ducommun 
Incorporated, higher compensation and benefits costs of $3.2 million, and higher stock-based compensation expense of $2.8 
million.
Restructuring Charges
Restructuring charges decreased $7.2 million (including the portion recorded in cost of sales which increased $0.9 million) in 
2024 compared to 2023 primarily due to the winding down of the restructuring plan that was approved and commenced in 
April 2022 that is expected to better position us for stronger performance. See Note 3 to our consolidated financial statements 
included in Part IV, Item 15(a) of this Form 10-K for further information.

Interest Expense
Interest expense decreased in 2024 compared to 2023 primarily due to the interest rate swaps that became effective as of 
January 1, 2024, along with a lower debt balance.
Income Tax Expense
We recorded an income tax expense of $5.4 million (an effective tax rate of 14.7%) in 2024, compared to $0.5 million (an 
effective tax rate of 2.8%) in 2023. The increase in the effective tax rate for 2024 compared to 2023 was primarily due to 
higher pre-tax income for 2024 compared to 2023, which caused the research and development tax credits to have a lower 
income tax benefit impact on the effective tax rate. The lower income tax benefit on the effective tax rate was partially offset 
by lower income tax expense related to non-deductible book compensation expenses.
Our unrecognized tax benefits were each $4.5 million in 2024 and 2023. We record interest and penalty charges, if any, 
related to uncertain tax positions as a component of tax expense and unrecognized tax benefits. The amounts accrued for 
interest and penalty charges as of December 31, 2024 and 2023 were not significant. If recognized, $2.5 million would affect 
the effective income tax rate. As a result of statute of limitations set to expire in 2025, we expect decreases to our 
unrecognized tax benefits of $0.5 million in the next twelve months.
We file U.S. Federal and state income tax returns. We are subject to examination by the Internal Revenue Service (“IRS”) for 
tax years after 2020 and by state taxing authorities for tax years after 2019. While we are no longer subject to examination 
prior to those periods, carryforwards generated prior to those periods may still be adjusted upon examination by the IRS or 
state taxing authority if they either have been or will be used in a subsequent period. We believe we have adequately accrued 
for tax deficiencies or reductions in tax benefits, if any, that could result from the examination and all open audit years.
The Tax Cuts and Jobs Act of 2017 (“TCJA”), which was signed into U.S. law in December 2017, eliminated the option to 
immediately deduct research and development expenditures in the year incurred under Section 174 effective January 1, 2022. 
The amended provision under Section 174 requires us to capitalize and amortize these expenditures over five years (for U.S.-
based research). For the year ended December 31, 2024, we recorded an increase to income taxes payable of $8.1 million and 
an increase to net deferred tax assets of a similar amount. We are monitoring legislation for any further changes to Section 
174 and the potential impact to our financial statements in 2025.
Net Income and Earnings per Diluted Share
Net income and earnings per diluted share for 2024 were $31.5 million, or $2.10 per diluted share, compared to net income 
and earnings per diluted share for 2023 of $15.9 million, or $1.14 per diluted share. The increase in net income in 2024 
compared to 2023 was primarily due to higher gross profit of $34.1 million, lower restructuring charges of $7.2 million 
(including the portion recorded in cost of sales which increased $0.9 million), and lower interest expense of $5.5 million, 
partially offset by higher SG&A expenses of $18.9 million, lower other income, net of $8.2 million, and higher income tax 
expense of $5.0 million.

Electronic Systems
Electronic Systems’ net revenues in 2024 compared to 2023 increased $1.2 million primarily due to the following:
•
$14.0 million higher revenues in our military and space end-use markets due to higher rates on selected missile, 
electronic warfare, radar, and naval and submarine platforms, partially offset by lower rates on selected fixed-
wing aircraft platforms; partially offset by
•
$2.4 million lower revenues in our commercial aerospace end-use markets due to lower revenues from in-flight 
entertainment, partially offset by higher rates on large aircraft and business jet platforms.
In addition, revenues for our industrial end-use markets for 2024 decreased $10.4 million compared to 2023 mainly due to 
our selectively pruning non-core business.
Electronic Systems segment operating income in 2024 compared to 2023 increased $31.6 million primarily due to higher 
engineered products revenues, strategic value pricing actions and the benefits of the restructuring plan.
Structural Systems
Structural Systems’ net revenues in 2024 compared to 2023 increased $28.3 million primarily due to the following:
•
$26.2 million higher revenues in commercial aerospace end-use markets due to growth in Airbus, higher rates 
on rotary-wing aircraft, and business jet platforms; and
•
$2.1 million higher revenues in military and space end-use markets due to higher rates on selected rotary-wing 
aircraft and ground vehicles platforms, partially offset by lower rates on selected missile platforms. 
The Structural Systems operating income in 2024 compared to 2023 increased $1.5 million primarily due to favorable 
manufacturing volume, lower Guaymas fire related expenses, lower inventory purchase accounting adjustments, partially 
offset by higher other manufacturing costs and unfavorable product mix.
In June 2020, a fire severely damaged our performance center in Guaymas, Mexico, which is part of our Structural Systems 
segment. We have insurance coverage and up to a capped amount, expect the damaged items will be covered, less our 
deductible. The full financial impact cannot be estimated at this time as we are currently working with our insurance carriers 
to determine the cause of the fire. The loss of production from the Guaymas performance center was absorbed by our other 
existing performance centers, however, we have reestablished and are in the process of ramping up our manufacturing 
capabilities in a different leased facility in Guaymas. A neighboring, non-related manufacturing facility, also suffered fire 
damage during the same time as the fire that severely damaged our Guaymas performance center and in July 2024, we 
received a subrogation demand from our landlord’s insurer, who also serves as one of our excess carriers, which we are 
currently evaluating and requested the insurer to enter into an informed consent and conflict of waiver agreement to which 
are awaiting a response. In the interim, discovery is ongoing, and we intend to defend these matters vigorously and believe 
we have substantial defenses in relation to these claims. Ultimate responsibility for the fire is still undetermined, and as such, 
there is no amount of loss that is probable and reasonably estimable at this time. If we are ultimately deemed to be 
responsible or partly responsible, it is possible we could incur a loss in excess of our insurance coverage limits, which could 
be material to our cash flow, liquidity, or financial results. See Note 14 and Note 16 to our consolidated financial statements 
included in Part IV, Item 15(a) of this Form 10-K for additional information.
In April 2023, a fire damaged a relatively small portion of one of our performance centers in our Structural Systems reporting 
segment. Our insurance covers damage, up to a capped amount, to the property and equipment at replacement cost, as well as 
business interruption and recovery related expenses caused by the fire, less our per claim deductible. There was a loss of 
production in this damaged portion of the performance center for a short period of time but did not result in significant 
disruption to customer delivery schedules. Production in this damaged portion has since resumed. The insurance claim for 
damages to our operating assets and business interruption was deemed final and closed by our insurance company during the 
fourth quarter of 2023 and since the remaining gain contingencies were deemed resolved, the remaining $0.3 million was 
recognized in the fourth quarter of 2023, for an aggregate total of $0.4 million recorded as other income during 2023. See

Corporate General and Administrative (“CG&A”) Expenses
CG&A expenses in 2024 compared to 2023 increased $9.8 million primarily due to higher professional services fees of $4.6 
million, of which $3.1 million was related to the unsolicited non-binding offer to acquire all the common stock outstanding of 
Ducommun Incorporated, higher stock-based compensation expense of $2.8 million, and higher compensation and benefits 
costs of $0.8 million.
Non-GAAP Financial Measures
Adjusted earnings before interest, taxes, depreciation, amortization, stock-based compensation expense, restructuring 
charges, professional fees related to unsolicited non-binding acquisition offer, Guaymas fire related expenses, other fire 
related expenses, insurance recoveries related to loss on operating assets, insurance recoveries related to business 
interruption, inventory purchase accounting adjustments, loss on extinguishment of debt, and other debt refinancing costs 
(“Adjusted EBITDA”) was $116.6 million and $101.5 million for the years ended December 31, 2024 and December 31, 
2023, respectively.
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 provides additional useful 
information that clarifies and enhances the understanding of the factors and trends affecting our past performance and future 
prospects. We define this measure, explain how it is calculated and provide a reconciliation of this measure to the most 
comparable GAAP measure in the table below. Adjusted EBITDA and the related financial ratios, as presented in this Form 
10-K, 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 income 
or any other performance measures derived in accordance with GAAP, or as an alternative to net cash provided by operating 
activities as a measurement 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 as a non-GAAP operating performance measure internally as a complementary financial measure 
to evaluate the performance and trends of our businesses. We 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 a substitute for 
analysis of our results as reported under GAAP. Some of these limitations include:
•
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 its usefulness as 
a comparative measure.
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 in this Form 10-K.
Even with the limitations above, we believe that Adjusted EBITDA is useful to an investor in evaluating our results of 
operations as this measure:

•
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;
•
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 income when calculating Adjusted 
EBITDA:
•
Interest expense may be useful to investors for determining current cash flow;
•
Income tax 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;
•
Restructuring charges 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;
•
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;
•
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 
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;
•
Loss on extinguishment of debt may be useful to our investors for determining current cash flow; and
•
Other debt refinancing costs may be useful to our investors in evaluating our core operating performance.
Reconciliations of net income to Adjusted EBITDA and the presentation of Adjusted EBITDA as a percentage of net 
revenues were as follows:

Backlog
We define backlog as customer placed purchase orders (“POs”) 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 may or may not be greater than the remaining performance obligations amount 
disclosed in Note 1 to our consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K. 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.
The increase in backlog was primarily in the military and space end-use markets; partially offset by a decrease in the 
commercial aerospace end-use markets and industrial end-use markets. $751.0 million of total backlog is expected to be 
delivered over the next 12 months. The following table summarizes our backlog for 2024 and 2023:

In July 2022, we completed a refinancing of all our existing debt by entering into a new term loan (“2022 Term Loan”) and a 
new revolving credit facility (“2022 Revolving Credit Facility”). The 2022 Term Loan is a $250.0 million senior secured loan 
that matures on July 14, 2027. The 2022 Revolving Credit Facility is a $200.0 million senior secured revolving credit facility 
that matures on July 14, 2027. The 2022 Term Loan and 2022 Revolving Credit Facility, collectively are the new credit 
facilities (“2022 Credit Facilities”). In conjunction with the closing of the 2022 Credit Facilities, we utilized the entire $250.0 
million of proceeds from the 2022 Term Loan plus our existing cash on hand to pay off our entire debt balance outstanding of 
$254.2 million under our prior credit facilities. At the same leverage ratio, the interest rate spread in the 2022 Credit Facilities 
is lower than the interest rate spread under our prior credit facilities. Interest payments are typically paid on a monthly or 
quarterly basis, depending on the interest rate selected, on the last business day each month or quarter. In addition, the 2022 
Term Loan requires quarterly amortization payments of 0.625% during year one and year two, 1.250% during year three and 
year four, and 1.875% during year five of the original outstanding principal balance of the 2022 Term Loan amount, on the 
last business day each quarter. Further, the undrawn portion of the commitment of the 2022 Revolving Credit Facility is 
subject to a commitment fee ranging from 0.175% to 0.275%, based upon the consolidated total net adjusted leverage ratio, 
typically paid on a quarterly basis, on the last business day each quarter. However, the 2022 Revolving Credit Facility does

not require any principal installment payments. As of December 31, 2024, we were in compliance with all covenants required 
under the 2022 Credit Facilities. See Note 10 to our consolidated financial statements included in Part IV, Item 15(a) of this 
Form 10-K for further information.
We made the mandatory quarterly amortization payments under our term loans of $7.8 million and $6.3 million during 2024 
and 2023, respectively. 
As of December 31, 2024, we had $191.0 million of unused borrowing capacity under the 2022 Revolving Credit Facility, 
after deducting $0.2 million for standby letters of credit.
In April 2022, management approved and commenced a restructuring plan that will position us for stronger performance. The 
restructuring plan mainly reduces headcount and consolidate facilities. As a result of this restructuring plan, we analyzed the 
need to write-down inventory and impair long-lived assets, including operating lease right-of-use assets. As of December 31, 
2024, we estimate the remaining amount of charges related to this initiative to be $1.0 million to $1.5 million in total pre-tax 
restructuring charges through 2025 for facility consolidation related expenses. On an annualized basis, we anticipate these 
restructuring actions will result in total cost savings of $11.0 million to $13.0 million. See Note 3 to our consolidated 
financial statements included in Part IV, Item 15(a) of this Form 10-K for further information.
In November 2021, we entered into derivative contracts, U.S. dollar-one month LIBOR forward interest rate swaps 
designated as cash flow hedges, all with an effective date of January 1, 2024, for an aggregate total notional amount of 
$150.0 million, weighted average fixed rate of 1.8%, and all terminating on January 1, 2031 (“Forward Interest Rate Swaps”). 
The Forward Interest Rate Swaps mature on a monthly basis, with fixed amount payer payment dates on the first day of each 
calendar month, commencing on February 1, 2024 through January 1, 2031. See Note 1, Note 4 , and Note 10 to our 
consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K for further information.
In July 2022, as a result of completing a refinancing of our existing debt, we were required to complete an amendment of the 
Forward Interest Rate Swaps (“Amended Forward Interest Rate Swaps”). The Forward Interest Rate Swaps were based on 
U.S. dollar-one month LIBOR and were amended to be based on one month Term SOFR as borrowings using LIBOR are no 
longer available under the 2022 Credit Facilities. The Amended Forward Interest Rate Swaps weighted average fixed rate 
was 1.7% as a result of the difference between U.S. dollar-one month LIBOR and one month Term SOFR. See Note 1, 
Note 4, and Note 10 to our consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K for further 
information.
In April 2023, we completed the acquisition of BLR. The initial purchase price for BLR was $115.0 million, net of cash 
acquired, all payable in cash. We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. We 
utilized the 2022 Revolving Credit Facility to complete the acquisition. See Note 2 to our consolidated financial statements 
included in Part IV, Item 15(a) of this Form 10-K for further information.
In May 2023, we completed a public offering of our common stock resulting in net proceeds of $85.1 million. The public 
stock offering net proceeds along with cash on hand were used to pay down $85.2 million on the 2022 Revolving Credit 
Facility that was drawn on and utilized to complete the acquisition of BLR. See Note 2, Note 10, and Note 11 to our 
consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K for further information.
We expect to spend a total of $23.0 million to $25.0 million for capital expenditures in 2025, financed by cash generated 
from operations, principally to support both growth in existing programs as well as new contract awards in Electronic 
Systems and Structural Systems. As part of our strategic plan to become a supplier of higher-level assemblies and win new 
contract awards, additional up-front investment in tooling will be required for newer programs which have higher engineering 
content and higher levels of complexity in assemblies.
We believe the ongoing aerospace and defense subcontractor consolidation makes acquisitions an increasingly important 
component of our future growth. We will continue to make prudent acquisitions and capital expenditures for manufacturing 
equipment and facilities to support long-term contracts for commercial and military aircraft and defense programs.
We continue to depend on operating cash flow and the availability of our 2022 Credit Facilities to provide short-term 
liquidity. Cash generated from operations and bank borrowing capacity is expected to provide sufficient liquidity to meet our 
obligations during the next twelve months from the date of issuance of these financial statements.
Cash Flow Summary
2024 Compared to 2023 
Net cash provided by operating activities during 2024 was $34.2 million, compared to $31.1 million during 2023. The higher 
Table of Contents
36
36

net cash provided by operating activities during 2024 was primarily due to higher net income, higher accounts payable 
mainly due to timing of payments, and lower inventories due to higher revenues, partially offset by higher contract assets due 
to higher revenues and lower contract liabilities due to lower net progress payments.
Net cash used in investing activities during 2024 was $13.9 million compared to $133.5 million during 2023. The lower net 
cash used in investing activities during 2024 was primarily due to an acquisition in the prior year that did not reoccur in the 
current year.
Net cash used in financing activities during 2024 was $26.0 million compared to net cash provided by of $99.0 million during 
2023. The higher net cash used in financing activities during 2024 was primarily due to in the prior year, $85.1 million net 
proceeds from the issuance of common stock in a public offering and $23.8 million net borrowings under the revolving credit 
facility for the acquisition of BLR that did not reoccur in the current year, and $15.0 million higher net repayments on the 
revolving credit facility in the current year.
2023 Compared to 2022 
See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2023 Form 10-K 
filed with the SEC on February 22, 2024.
Off-Balance Sheet Arrangements
Our off-balance sheet arrangements consist of operating and finance leases not recorded as a result of the practical expedients 
utilized, right of offset of industrial revenue bonds and associated failed sales-leasebacks on property and equipment, and 
indemnities, none of which we believe may have a material current or future effect on our financial condition, liquidity, 
capital resources, or results of operations.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Critical accounting policies and estimates are those accounting policies and estimates that can have a significant impact on 
the presentation of our financial condition and results of operations and that require the use of subjective estimates based 
upon past experience and management’s judgment. Because of the uncertainty inherent in such estimates, actual results may 
differ from these estimates. Below are those policies applied in preparing our financial statements that management believes 
are the most dependent on the application of estimates and assumptions. See Note 1 to our consolidated financial statements 
included in Part IV, Item 15(a) of this Form 10-K for additional accounting policies.
Revenue Recognition
Our customers typically engage us to manufacture products based on designs and specifications provided by the end-use 
customer. This requires the building of tooling and manufacturing first article inspection products (prototypes) before volume 
manufacturing. Contracts with our customers generally include a termination for convenience clause.
We have a significant number of contracts that are started and completed within the same year, as well as contracts derived 
from long-term agreements and programs that can span several years. We recognize revenue under ASC 606, “Revenue from 
Contracts with Customers” (“ASC 606”), which utilizes a five-step model.
The definition of a contract for us is typically defined as a customer purchase order as this is when we achieve an enforceable 
right to payment. The majority of our contracts are firm fixed-price contracts. The deliverables within a customer purchase 
order are analyzed to determine the number of performance obligations. In addition, at times, in order to achieve economies 
of scale and based on our customer’s forecasted demand, we may build in advance of receiving a purchase order from our 
customer. When that occurs, we would not recognize revenue until we have received the customer purchase order.
A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of 
account under ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as 
revenue when, or as, control is transferred and the performance obligation is satisfied. The majority of our contracts have a 
single performance obligation as the promise to transfer the individual goods or services are highly interrelated or met the 
series guidance. For contracts with multiple performance obligations, we allocate the contract transaction price to each 
performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. 
The primary method used to estimate the standalone selling price is the expected cost plus a margin approach, under which 
we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct 
good or service.
We manufacture most products to customer specifications, and the product cannot be easily modified for another customer. 
Table of Contents
37
37

As such, these products are deemed to have no alternative use once the manufacturing process begins. In the event the 
customer invokes a termination for convenience clause, we would be entitled to costs incurred to date plus a reasonable 
profit. Contract costs typically include labor, materials, overhead, and when applicable, subcontractor costs. For most of our 
products, we are building assets with no alternative use and have enforceable right to payment, and thus, we recognize 
revenue using the over time method.
The majority of our performance obligations are satisfied over time as work progresses. Typically, revenue is recognized over 
time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion, also known as cost-to-
cost plus reasonable profit) to measure progress. Our typical revenue contract is a firm fixed price contract, and the cost of 
raw materials could make up a significant amount of the total costs incurred. As such, we believe using the total costs 
incurred input method would be the most appropriate method. While the cost of raw materials could make up a significant 
amount of the total costs incurred, there is a direct relationship between our inputs and the transfer of control of goods or 
services to the customer.
Contract estimates, known as “estimates at completion,” are based on various assumptions to project the outcome of future 
events that can span multiple months or years. These assumptions include among others, actual gross profits on the same or 
similar products manufactured previously; labor productivity and availability; the complexity of the work to be performed; 
the cost and availability of materials; overhead cost rates; and the performance of subcontractors. As a significant change in 
one or more of these estimates could affect the progress completed (and related profitability) on our contracts, we review and 
update our contract-related estimates on a regular basis. We recognize such adjustments under the cumulative catch-up 
method. Under this method, the impact of the adjustment is recognized in the period the adjustment is identified. In any given 
reporting period, we have a large number of active contracts, which we have defined as a customer purchase order, and 
changes in estimates may occur on a significant number of these contracts. Given the significant number of contracts that we 
may have at any given point in time, the varied nature of products produced under such contracts, and the different 
assumptions, facts and circumstances associated with each individual contract, and the fact that such changes at the contract 
level are typically not material, we disclose cumulative catch-up adjustments on a net basis. See Note 1 to our consolidated 
financial statements included in Part IV, Item 15(a) of this Form 10-K for the net impact of these adjustments to our 
consolidated financial statements for 2024 and 2023.
Payments under long-term contracts may be received before or after revenue is recognized. When revenue is recognized 
before we bill our customer, a contract asset is created for the work performed but not yet billed. Similarly, when we receive 
payment before we ship our products to our customer and have met the shipping terms, a contract liability is created for the 
advance or progress payment. When a contract liability and a contract asset exist on the same contract, we report it on a net 
basis.
We record provisions for the total anticipated losses on contracts, considering total estimated costs to complete the contract 
compared to total anticipated revenues, in the period in which such losses are identified. The provisions for estimated losses 
on contracts require us to make certain estimates and assumptions, including those with respect to the future revenue under a 
contract and the future cost to complete the contract. Our estimate of the future cost to complete a contract may include 
assumptions as to changes in manufacturing efficiency, operating and material costs, and our ability to resolve claims and 
assertions with our customers. If any of these or other assumptions and estimates do not materialize in the future, we may be 
required to adjust the provisions for estimated losses on contracts. The provision for estimated losses on contracts is included 
as part of contract liabilities on the consolidated balance sheets. 
Production cost of contracts includes non-recurring production costs, such as design and engineering costs, and tooling and 
other special-purpose machinery necessary to build parts as specified in a contract. Production costs of contracts are recorded 
to cost of sales using the over time revenue recognition model. We review the value of the production cost of contracts on a 
quarterly basis to ensure when added to the estimated cost to complete, the value is not greater than the estimated realizable 
value of the related contracts. 
Business Combinations
When a business is acquired, we allocate the purchase price by recording the assets acquired and liabilities assumed at their 
estimated fair values as of the acquisition date, with the excess cost recorded as goodwill. A preliminary fair value is 
determined once a business is acquired, with the final determination of fair value to be completed no later than one year from 
the date of acquisition. 
To determine the estimated fair value of assets acquired and liabilities assumed requires significant judgment and estimates, 
including the selection of valuation methodologies, estimates of future revenues, costs and cash flows, discount rates, and 
Table of Contents
38
38

selection of comparable companies. We engage the assistance of valuation specialists in concluding on fair value 
measurements in determining the fair value of assets acquired and liabilities assumed in business combinations. 
The fair value of the intangible assets is estimated using several valuation methodologies, including the income based or 
market based approaches, which represent Level 3 fair value measurements. Inputs to fair value analyses and other aspects of 
the allocation of the purchase price require judgment. The values for technology and trade name are typically estimated using 
the relief from royalty methodology, while the value for customer relationships is typically estimated based on a multi-period 
excess earnings approach. The more significant inputs used in the technology intangible asset valuation included (i) future 
revenues, (ii) the technology decay rate, (iii) the royalty rate, and (iv) the discount rate. The more significant inputs used in 
the customer relationships intangible asset valuation include (i) future revenues, (ii) the projected earnings before interest, 
taxes, and amortization (“EBITA”) margins, (iii) the customer attrition rates, and (iv) the discount rate. The useful lives are 
estimated based on the underlying agreements or the future economic benefit expected to be received from the assets. 
Acquisition related costs are not included as components of consideration transferred but instead, expensed as incurred and 
are included in selling, general and administrative expenses in our consolidated statements of income. See Note 2 to our 
consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K.
Goodwill
Goodwill is evaluated for impairment on an annual basis on the first day of the fourth fiscal quarter. If certain factors occur, 
including significant under performance of our business relative to expected operating results, significant adverse economic 
and industry trends, significant decline in our market capitalization for an extended period of time relative to net book value, 
a decision to divest individual businesses within a reporting unit, or a decision to group individual businesses differently, we 
may be required to perform an interim impairment test prior to the fourth quarter. 
We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment. The 
qualitative approach for potential impairment analysis is performed by evaluating a number of qualitative factors to determine 
whether it is more likely than not that the fair value of a reporting unit was less than its carrying amount. If the qualitative 
assessment indicates that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, we 
perform a quantitative assessment.
The quantitative approach for potential impairment analysis is performed by comparing the fair value of a reporting unit to its 
carrying value, including goodwill. Fair value is estimated by management using a combination of the income approach 
(which is based on a discounted cash flow model) and the market approach. Management’s cash flow projections include 
significant judgments and assumptions, including the amount and timing of expected cash flows, long-term growth rates, and 
discount rates. The cash flows used in the discounted cash flow model are based on our best estimate of future revenues, 
gross margins, and adjusted after-tax earnings. If any of these assumptions are incorrect, it will impact the estimated fair 
value of a reporting unit. The market approach also requires management judgment in selecting comparable companies, 
business acquisitions and the transaction values observed and its related control premiums.
In the fourth quarter of 2024, the carrying amount of goodwill at the date of the most recent annual impairment evaluation for 
Electronic Systems and Structural Systems was $117.4 million and $127.2 million, respectively. For both reporting units, we 
performed a quantitative (step one) goodwill impairment analysis. The fair value of our Electronic Systems and Structural 
Systems segments exceeded their respective carrying values and thus, were not deemed impaired.
Other Intangible Assets
We amortize acquired other intangible assets with finite lives over the estimated economic lives of the assets, ranging from 2 
to 23 years, generally using the straight-line method. The value of other intangibles acquired through business combinations 
has been estimated using present value techniques which involve estimates of future cash flows. We evaluate other intangible 
assets for recoverability considering undiscounted cash flows when significant changes in conditions occur, and recognize 
impairment losses, if any, based upon the estimated fair value of the assets.
Accounting for Stock-Based Compensation
We measure and recognize compensation expense for share-based payment transactions to our employees and non-employees 
at their estimated fair value. The expense is measured at the grant date, based on the calculated fair value of the share-based 
award, and is recognized over the requisite service period (generally the vesting period of the equity award). The fair value of 
stock options is determined using the Black-Scholes-Merton (“Black-Scholes”) valuation model, which requires assumptions 
and judgments regarding stock price volatility, risk-free interest rates, and expected options terms. Management’s estimates 
could differ from actual results. The fair value of unvested stock awards is determined based on the closing price of the

underlying common stock on the date of grant except for market condition awards for which the fair value was based on a 
Monte Carlo simulation model.
Inventories
Inventories are stated at the lower of cost or net realizable value with cost being determined using a moving average cost 
basis for raw materials and actual cost for work-in-process and finished goods. The majority of our inventory is charged to 
cost of sales as raw materials are placed into production. Inventoried costs include raw materials, outside processing, direct 
labor and allocated overhead, adjusted for any abnormal amounts of idle performance center expense, freight, handling costs, 
and wasted materials (spoilage) incurred. We assess the inventory carrying value and reduce it, if necessary, to its net 
realizable value based on customer orders on hand, and internal demand forecasts using management’s best estimates given 
information currently available. The majority of our revenues are recognized over time, however, for revenue contracts where 
revenue is recognized using the point in time method, inventory is not reduced until it is shipped or transfer of control to the 
customer has occurred. Our ending inventory consists of raw materials, work-in-process, and finished goods.
Income Taxes
Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and 
liabilities. Deferred tax assets and liabilities are recognized, using enacted tax rates, for the expected future tax consequences 
of temporary differences between the book and tax bases of recorded assets and liabilities, operating losses, and tax credit 
carryforwards. Deferred tax assets are evaluated quarterly and are reduced by a valuation allowance if it is more likely than 
not that some portion or all of the deferred tax assets will not be realized.
Tax positions taken or expected to be taken in a tax return are recognized when it is more-likely-than-not, based on technical 
merits, to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of 
benefit that is greater than 50% likely of being realized upon ultimate settlement, including resolution of related appeals and/
or litigation process, if any.
Recent Accounting Pronouncements
See Note 1 to our consolidated financial statements included in Part IV, Item 15(a) of this Form 10-K for a description of 
recent accounting pronouncements.
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Our main market risk exposure relates to changes in interest rates on our outstanding long-term debt. At December 31, 2024, 
we had borrowings of $243.2 million under our 2022 Credit Facilities.
The 2022 Term Loan bears interest, at our option, at a rate equal to either (i) Term Secured Overnight Financing Rate (“Term 
SOFR”) plus an applicable margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] 
Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is 
less than zero percent, it will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in 
each case based upon the consolidated total net adjusted leverage ratio.
The 2022 Revolving Credit Facility bears interest, at our option, at a rate equal to either (i) Term SOFR plus an applicable 
margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] Federal Funds Rate plus 
0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is less than zero percent, it 
will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in each case based upon the 
consolidated total net adjusted leverage ratio. 
A hypothetical 10% increase or decrease in the interest rate would have an immaterial impact on our financial condition and 
results of operations.

ITEM 9A. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, 
as amended (“Exchange Act”)), are designed to provide reasonable assurance that information required to be disclosed in 
reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods 
specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, 
including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding 
required disclosures.
Under the supervision and with the participation of our management, including the Chief Executive Officer and the Chief 
Financial Officer, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and 
procedures as of the end of the period covered by this Annual Report on Form 10-K. Based on this evaluation, the 
Company’s Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were 
effective at the reasonable assurance level as of December 31, 2024.
Management’s Report on Internal Control Over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in 
Rules 13a-15(f) and 15d-15(f) under the Exchange Act. The Company’s internal control over financial reporting is a process 
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial 
statements for external purposes in accordance with generally accepted accounting principles (“GAAP”). The Company’s 
internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records 
that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) 
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with 
authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or 
timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on 
our financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Management of the Company has assessed the effectiveness of the Company’s internal control over financial reporting as of 
December 31, 2024. In making this assessment, management used the criteria set forth by the Committee of Sponsoring 
Organizations of the Treadway Commission (“COSO”) Internal Control-Integrated Framework (2013). Based on our 
assessment and those criteria, management concluded that the Company’s internal control over financial reporting was 
effective as of December 31, 2024.
The effectiveness of the Company’s internal control over financial reporting as of December 31, 2024 has been audited by 
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included in 
Item 15 of this Annual Report on Form 10-K.
Remediation of Prior Year Material Weakness
We previously identified and disclosed in our 2023 Annual Report on Form 10-K, as well as in our Quarterly Report on Form 
10-Q (“Form 10-Q”) for each interim period in fiscal year 2024, a material weakness in our internal control over financial 
reporting regarding the following:
We did not design and maintain effective controls over the accuracy of contract terms and the reasonableness of gross margin 
assumptions used to recognize revenue. Specifically, we did not verify that amendments to purchase orders and gross margin 
percentage assumptions used in the Company’s revenue recognition analysis were properly reviewed at a sufficient level of 
precision.
During 2024, we successfully completed the testing necessary to conclude that the controls were operating effectively as of 
December 31, 2024 and have concluded that the material weakness related to revenue recognition has been remediated.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders of Ducommun Incorporated
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Ducommun Incorporated and its subsidiaries (the 
“Company”) as of December 31, 2024 and 2023, and the related consolidated statements of income, of comprehensive 
income, of changes in shareholders’ equity and of cash flows for each of the three years in the period ended December 31, 
2024, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)2 
(collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control 
over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework 
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of 
the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the 
United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control 
over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework 
(2013) issued by the COSO.
Basis for Opinions
The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal 
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, 
included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility 
is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over 
financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting 
Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance 
with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and 
the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform 
the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material 
misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in 
all material respects. 
Our audits of the consolidated financial statements included performing procedures to assess the risks of material 
misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond 
to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 
consolidated financial statements. Our audits also included evaluating the accounting principles used and significant 
estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our 
audit of internal control over financial reporting included obtaining an understanding of internal control over financial 
reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness 
of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered 
necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to 
permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or 
disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, 
or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Goodwill Impairment Assessment - Structural Systems Reporting Unit
As described in Notes 1 and 8 to the consolidated financial statements, the Company’s consolidated goodwill balance was 
$244.6 million as of December 31, 2024, and the goodwill associated with the Structural Systems reporting unit was $127.2 
million. Goodwill is evaluated for impairment on an annual basis on the first day of the fourth fiscal quarter. If certain factors 
occur, management may be required to perform an interim impairment test prior to the fourth quarter. The quantitative 
approach for potential impairment analysis is performed by comparing the fair value of a reporting unit to its carrying value, 
including goodwill. Fair value is estimated by management using a combination of the income approach (which is based on a 
discounted cash flow model) and the market approach. Management’s cash flow projections include significant judgments 
and assumptions, including the amount and timing of expected cash flows, long-term growth rates, and discount rates. The 
cash flows used in the discounted cash flow model are based on management’s best estimate of future revenues, gross 
margins, and adjusted after-tax earnings. The market approach also requires management judgment in selecting comparable 
companies, business acquisitions and the transaction values observed and its related control premiums. 
The principal considerations for our determination that performing procedures relating to the goodwill impairment 
assessment of the Structural Systems reporting unit is a critical audit matter are (i) the significant judgment by management 
when developing the fair value estimate of the Structural Systems reporting unit based on a discounted cash flow model; (ii) a 
high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant 
assumptions related to the estimate of gross margins and the discount rate; and (iii) the audit effort involved the use of 
professionals with specialized skill and knowledge. 
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall 
opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to 
management’s goodwill impairment assessment, including controls over the valuation of the Structural Systems reporting 
unit. These procedures also included, among others (i) testing management’s process for developing the fair value estimate of 
the Structural Systems reporting unit based on a discounted cash flow model; (ii) evaluating the appropriateness of the 
discounted cash flow model used by management; (iii) testing the completeness and accuracy of underlying data used in the 
discounted cash flow model; and (iv) evaluating the reasonableness of the significant assumptions used by management 
related to the estimate of gross margins and the discount rate. Evaluating management’s assumption related to the estimate of 
gross margins involved evaluating whether the assumption used by management was reasonable considering (i) the current 
and past performance of the Structural Systems reporting unit; (ii) the consistency with external market and industry data; and 
(iii) whether the assumption was consistent with evidence obtained in other areas of the audit. Professionals with specialized 
skill and knowledge were used to assist in evaluating (i) the appropriateness of the discounted cash flow model and (ii) the 
reasonableness of the discount rate assumption.

DUCOMMUN INCORPORATED AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note 1. Summary of Significant Accounting Policies
Description of Business
We are a leading global provider of innovative, value-added proprietary products and manufacturing solutions for high-
performance products and high-cost-of failure applications used primarily in the aerospace and defense (“A&D”), industrial, 
medical, and other industries (collectively, “Industrial”). Our operations are organized into two primary businesses:  
Electronic Systems segment (“Electronic Systems”) and Structural Systems segment (“Structural Systems”), each of which is 
a reportable operating segment. Electronic Systems designs, engineers and manufactures high-reliability electronic and 
electromechanical products used in worldwide technology-driven markets including A&D and Industrial end-use markets. 
Electronic Systems’ product offerings primarily range from prototype development to complex assemblies. Structural 
Systems designs, engineers and manufactures large, complex contoured aerostructure components and assemblies and 
supplies composite and metal bonded structures and assemblies. Structural Systems’ products are primarily used on 
commercial aircraft, military fixed-wing aircraft, and military and commercial rotary-wing aircraft. All reportable operating 
segments follow the same accounting principles. 
Basis of Presentation
The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the 
United States of America (“GAAP”), and include the accounts of Ducommun Incorporated and its subsidiaries 
(“Ducommun,” the “Company,” “we,” “us” or “our”), after eliminating intercompany balances and transactions.
Our fiscal quarters typically end on the Saturday closest to the end of March, June and September for the first three fiscal 
quarters of each year, and on December 31 for our fourth fiscal quarter. As a result of using fiscal quarters for the first three 
quarters combined with leap years, our first and fourth fiscal quarters can range between 12 1/2 weeks to 13 1/2 weeks while 
the second and third fiscal quarters remain at a constant 13 weeks per fiscal quarter.
Use of Estimates
Certain amounts and disclosures included in the consolidated financial statements required management to make estimates 
and judgments that affect the amount of assets, liabilities (including forward loss reserves), revenues and expenses, and 
related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other 
assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making 
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results 
could differ from these estimates.
Reclassifications
Certain prior period amounts have been reclassified to conform to current year’s presentation.
Unsolicited Non-Binding Indication of Interest
On April 8, 2024, our Board of Directors (“BOD”) confirmed receipt of the first unsolicited non-binding indication of interest  
dated April 1, 2024 (“First IOI”) from Albion River LLC (“Albion”), a private direct investment firm. Albion expressed 
interest in acquiring all the outstanding shares of Ducommun for $60.00 per share in cash. On April 16, 2024, we issued a 
press release responding to the First IOI that the BOD had unanimously determined it was not in the best interests of 
Ducommun and Ducommun shareholders to pursue further discussions regarding the proposal. 
On July 15, 2024, our BOD received an unsolicited revised non-binding indication of interest from Albion (“Second IOI”), to 
acquire all outstanding shares of Ducommun for $65.00 per share in cash. On July 25, 2024, we issued a press release 
responding to the Second IOI that the BOD had unanimously determined it was not in the best interests of Ducommun and 
Ducommun shareholders to pursue further discussions regarding the revised proposal.

On November 12, 2024 Albion filed a 13D/A with the SEC stating that it no longer intended to maintain an active role with 
Ducommun and that it had reduced its stock ownership to 737,992 shares. Subsequent to our year ended December 31, 2024, 
on February 10, 2025, Albion filed a 13G/A with the SEC showing it completely liquidated its holdings and no longer owned 
any shares in Ducommun as of December 31, 2024.

Fair Value
Assets and liabilities that are measured, recorded or disclosed at fair value on a recurring basis are categorized using the fair 
value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine the fair 
value. Level 1, the highest level, refers to the values determined based on quoted prices in active markets for identical assets. 
Level 2 refers to fair values estimated using significant observable inputs. Level 3, the lowest level, includes fair values 
estimated using significant unobservable inputs.
We have money market funds which are included as cash and cash equivalents. We also have forward interest rate swap 
agreements and the fair value of the forward interest rate swap agreements was determined using pricing models that use 
observable market inputs as of the balance sheet date, a Level 2 measurement.
There were no transfers between Level 1, Level 2, or Level 3 financial instruments in either 2024 or 2023.
Cash and Cash Equivalents
Cash equivalents consist of highly liquid instruments purchased with original maturities of three months or less. These assets 
are valued at cost, which approximates fair value, which we classify as Level 1. See Fair Value above.
Derivative Instruments
We recognize derivative instruments on our consolidated balance sheets at their fair value. On the date that we enter into a 
derivative contract, we designate the derivative instrument as a fair value hedge, a cash flow hedge, or a derivative instrument 
that will not be accounted for using hedge accounting methods. In November 2021, we entered into forward interest rate 
swap agreements with an aggregate notional amount of $150.0 million, all with an effective date of January 1, 2024 
(“Forward Interest Rate Swaps”) to manage our exposure to interest rate movements on a portion of our debt. As such, at the 
time we entered into the Forward Interest Rate Swaps, there was a high probability of forecasted interest payments on our 
debts occurring and the swaps are highly effective in offsetting those interest payments and therefore, we elected to apply 
cash flow hedge accounting. In July 2022, as a result of refinancing all our existing debt, which allows borrowing based on a 
Secured Overnight Financing Rate (“SOFR”), we were required to complete an amendment of the Forward Interest Rate 
Swaps from One Month London Interbank Offered Rate (“LIBOR”) to One Month Term SOFR (“Amended Forward Interest 
Rate Swaps”), which occurred on the same day. After the transition of the Forward Interest Rate Swaps and debt to SOFR 
was completed, we determined the hedging relationship was still highly effective as of the amendment date. See Note 4 and 
Note 10. As of December 31, 2024, all of our derivative instruments were designated as cash flow hedges.
We record changes in the fair value of a derivative instrument that is highly effective and that is designated and qualifies as a 
cash flow hedge in other comprehensive income (loss), net of tax until our earnings are affected by the variability of cash 
flows of the underlying hedged item. We report changes in the fair values of derivative instruments that are not designated or 
do not qualify for hedge accounting in current period earnings. We classify cash flows from derivative instruments in the 
consolidated statements of cash flows in the same category as the item being hedged or on a basis consistent with the nature 
of the instrument. Prior to the Amended Forward Interest Rate Swaps being effective on January 1, 2024, we only recorded 
the changes in fair value of the derivative instruments that were highly effective and that were designated and qualified as 
cash flow hedges prior to the effective date. See Note 4.
Table of Contents
54
54

When we determine that a derivative instrument is not highly effective as a hedge, we discontinue hedge accounting 
prospectively. In all situations in which we discontinue hedge accounting and the derivative instrument remains outstanding, 
we will carry the derivative instrument at its fair value on our consolidated balance sheets and recognize subsequent changes 
in its fair value in our current period earnings.
Allowance for Credit Losses
We maintain an allowance for credit losses for expected losses from the inability of customers to make required payments. 
The allowance for credit losses is evaluated periodically for expected credit losses based on the financial condition of 
customers and their payment history, the aging of accounts receivable, historical write-off experience and other assumptions, 
such as current assessment of economic conditions.
Inventories
Inventories are stated at the lower of cost or net realizable value with cost being determined using a moving average cost 
basis for raw materials and actual cost for work-in-process and finished goods. The majority of our inventory is charged to 
cost of sales as raw materials are placed into production. Inventoried costs include raw materials, outside processing, direct 
labor and allocated overhead, adjusted for any abnormal amounts of idle performance center expense, freight, handling costs, 
and wasted materials (spoilage) incurred. We assess the inventory carrying value and reduce it, if necessary, to its net 
realizable value based on customer orders on hand, and internal demand forecasts using management’s best estimates given 
information currently available. The majority of our revenues are recognized over time, however, for revenue contracts where 
revenue is recognized using the point in time method, inventory is not reduced until it is shipped or transfer of control to the 
customer has occurred. Our ending inventory consists of raw materials, work-in-process, and finished goods.
Property and Equipment and Depreciation
Property and equipment, including assets recorded under operating and finance leases, are recorded at cost. Depreciation and 
amortization are computed using the straight-line method over the estimated useful lives of the related assets, or the lease 
term if shorter for leasehold improvements. Repairs and maintenance are charged to expense as incurred. We evaluate long-
lived assets for recoverability considering undiscounted cash flows, when significant changes in conditions occur, and 
recognize impairment losses if any, based upon the fair value of the assets.
Business Combinations
When a business is acquired, we allocate the purchase price by recording the assets acquired and liabilities assumed at their 
estimated fair values as of the acquisition date, with the excess cost recorded as goodwill. A preliminary fair value is 
determined once a business is acquired, with the final determination of fair value to be completed no later than one year from 
the date of acquisition. 
To determine the estimated fair value of assets acquired and liabilities assumed requires significant judgment and estimates, 
including the selection of valuation methodologies, estimates of future revenues, costs and cash flows, discount rates, and 
selection of comparable companies. We engage the assistance of valuation specialists in concluding on fair value 
measurements in determining the fair value of assets acquired and liabilities assumed in business combinations. 
The fair value of the intangible assets is estimated using several valuation methodologies, including the income based or 
market based approaches, which represent Level 3 fair value measurements. Inputs to fair value analyses and other aspects of 
the allocation of the purchase price require judgment. The values for technology and trade name are typically estimated using 
the relief from royalty methodology, while the value for customer relationships is typically estimated based on a multi-period 
excess earnings approach. The more significant inputs used in the technology intangible asset valuation included (i) future 
revenues, (ii) the technology decay rate, (iii) the royalty rate, and (iv) the discount rate. The more significant inputs used in 
the customer relationships intangible asset valuation include (i) future revenues, (ii) the projected earnings before interest, 
taxes, and amortization (“EBITA”) margins, (iii) the customer attrition rates, and (iv) the discount rate. The useful lives are 
estimated based on the underlying agreements or the future economic benefit expected to be received from the assets. 
Acquisition related costs are not included as components of consideration transferred but instead, expensed as incurred and 
are included in selling, general and administrative expenses in our consolidated statements of income. See Note 2.

Goodwill
Goodwill is evaluated for impairment on an annual basis on the first day of the fourth fiscal quarter. If certain factors occur, 
including significant under performance of our business relative to expected operating results, significant adverse economic 
and industry trends, significant decline in our market capitalization for an extended period of time relative to net book value, 
a decision to divest individual businesses within a reporting unit, or a decision to group individual businesses differently, we 
may be required to perform an interim impairment test prior to the fourth quarter. 
We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment. The 
qualitative approach for potential impairment analysis is performed to determine whether it is more likely than not that the 
fair value of a reporting unit was less than its carrying amount. If the qualitative assessment indicates that it is more-likely-
than-not that the fair value of a reporting unit is less than its carrying value, we perform a quantitative assessment.
The quantitative approach for potential impairment analysis is performed by comparing the fair value of a reporting unit to its 
carrying value, including goodwill. Fair value is estimated by management using a combination of the income approach 
(which is based on a discounted cash flow model) and the market approach. Management’s cash flow projections include 
significant judgments and assumptions, including the amount and timing of expected cash flows, long-term growth rates, and 
discount rates. The cash flows used in the discounted cash flow model are based on our best estimate of future revenues, 
gross margins, and adjusted after-tax earnings. If any of these assumptions are incorrect, it will impact the estimated fair 
value of a reporting unit. The market approach also requires management judgment in selecting comparable companies, 
business acquisitions and the transaction values observed and its related control premiums.
In the fourth quarter of 2024, the carrying amount of goodwill at the date of the most recent annual impairment evaluation for 
Electronic Systems and Structural Systems was $117.4 million and $127.2 million, respectively. We performed a step one 
goodwill impairment analysis as of the first day of the fourth quarter of 2024 for both Electronic Systems and Structural 
Systems. The fair value of both Electronic Systems and Structural Systems exceeded its respective carrying values and thus, 
were not deemed to be impaired. See Note 8.
We acquired 100% of the equity interests of BLR Aerospace, L.L.C. (“BLR”) in April 2023, for an initial purchase price of 
$115.0 million, net of cash acquired. We recorded goodwill of $41.2 million in our Structural Systems segment, which is also 
our reporting unit. See Note 2.
Other Intangible Assets
We amortize acquired other intangible assets with finite lives over the estimated economic lives of the assets, ranging from 2 
to 23 years, generally using the straight-line method. The value of other intangibles acquired through business combinations 
has been estimated using present value techniques which involve estimates of future cash flows. We evaluate other intangible 
assets for recoverability considering undiscounted cash flows when significant changes in conditions occur, and recognize 
impairment losses, if any, based upon the estimated fair value of the assets.
Accumulated Other Comprehensive Income
Accumulated other comprehensive income, as reflected on the consolidated balance sheets under the equity section, was 
comprised of cumulative pension and retirement liability adjustments, net of tax, and change in net unrealized gains and 
losses on cash flow hedges, net of tax.
Revenue Recognition
Our customers typically engage us to manufacture products based on designs and specifications provided by the end-use 
customer. This requires the building of tooling and manufacturing first article inspection products (prototypes) before volume 
manufacturing. Contracts with our customers generally include a termination for convenience clause.
We have a significant number of contracts that are started and completed within the same year, as well as contracts derived 
from long-term agreements and programs that can span several years. We recognize revenue under ASC 606, “Revenue from 
Contracts with Customers” (“ASC 606”), which utilizes a five-step model.
The definition of a contract for us is typically defined as a customer purchase order as this is when we achieve an enforceable 
right to payment. The majority of our contracts are firm fixed-price contracts. The deliverables within a customer purchase 
order are analyzed to determine the number of performance obligations. In addition, at times, in order to achieve economies 
of scale and based on our customer’s forecasted demand, we may build in advance of receiving a purchase order from our 
customer. When that occurs, we would not recognize revenue until we have received the customer purchase order.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of 
account under ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as 
revenue when, or as, control is transferred and the performance obligation is satisfied. The majority of our contracts have a 
single performance obligation as the promise to transfer the individual goods or services are highly interrelated or met the 
series guidance. For contracts with multiple performance obligations, we allocate the contract transaction price to each 
performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. 
The primary method used to estimate the standalone selling price is the expected cost plus a margin approach, under which 
we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct 
good or service.
We manufacture most products to customer specifications, and the product cannot be easily modified for another customer. 
As such, these products are deemed to have no alternative use once the manufacturing process begins. In the event the 
customer invokes a termination for convenience clause, we would be entitled to costs incurred to date plus a reasonable 
profit. Contract costs typically include labor, materials, overhead, and when applicable, subcontractor costs. For most of our 
products, we are building assets with no alternative use and have enforceable right to payment, and thus, we recognize 
revenue using the over time method.
The majority of our performance obligations are satisfied over time as work progresses. Typically, revenue is recognized over 
time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion, also known as cost-to-
cost plus reasonable profit) to measure progress. Our typical revenue contract is a firm fixed price contract, and the cost of 
raw materials could make up a significant amount of the total costs incurred. As such, we believe using the total costs 
incurred input method would be the most appropriate method. While the cost of raw materials could make up a significant 
amount of the total costs incurred, there is a direct relationship between our inputs and the transfer of control of goods or 
services to the customer.
Contract estimates, known as “estimates at completion,” are based on various assumptions to project the outcome of future 
events that can span multiple months or years. These assumptions include among others, actual gross profits on the same or 
similar products manufactured previously; labor productivity and availability; the complexity of the work to be performed; 
the cost and availability of materials; overhead cost rates; and the performance of subcontractors. As a significant change in 
one or more of these estimates could affect the progress completed (and related profitability) on our contracts, we review and 
update our contract-related estimates on a regular basis. We recognize such adjustments under the cumulative catch-up 
method. Under this method, the impact of the adjustment is recognized in the period the adjustment is identified. In any given 
reporting period, we have a large number of active contracts, which we have defined as a customer purchase order, and 
changes in estimates may occur on a significant number of these contracts. Given the significant number of contracts that we 
may have at any given point in time, the varied nature of products produced under such contracts, and the different 
assumptions, facts and circumstances associated with each individual contract, and the fact that such changes at the contract 
level are typically not material, we disclose cumulative catch-up adjustments on a net basis. 
Net cumulative favorable and unfavorable catch-up adjustments to contracts had the following impact on our operating 
results:

Payments under long-term contracts may be received before or after revenue is recognized. When revenue is recognized 
before we bill our customer, a contract asset is created for the work performed but not yet billed. Similarly, when we receive 
payment before we ship our products to our customer and have met the shipping terms, a contract liability is created for the 
advance or progress payment. When a contract liability and a contract asset exist on the same contract, we report it on a net 
basis.
We record provisions for the total anticipated losses on contracts, considering total estimated costs to complete the contract 
compared to total anticipated revenues, in the period in which such losses are identified. The provisions for estimated losses 
on contracts require us to make certain estimates and assumptions, including those with respect to the future revenue under a 
contract and the future cost to complete the contract. Our estimate of the future cost to complete a contract may include 
assumptions as to changes in manufacturing efficiency, operating and material costs, and our ability to resolve claims and 
assertions with our customers. If any of these or other assumptions and estimates do not materialize in the future, we may be

required to adjust the provisions for estimated losses on contracts. The provision for estimated losses on contracts is included 
as part of contract liabilities on the consolidated balance sheets. As of December 31, 2024 and December 31, 2023, provision 
for estimated losses on contracts were $4.7 million and $5.4 million, respectively. It is reasonably possible we may incur 
additional losses in the future.
Production cost of contracts includes non-recurring production costs, such as design and engineering costs, and tooling and 
other special-purpose machinery necessary to build parts as specified in a contract. Production costs of contracts are recorded 
to cost of sales using the over time revenue recognition model. We review the value of the production cost of contracts on a 
quarterly basis to ensure when added to the estimated cost to complete, the value is not greater than the estimated realizable 
value of the related contracts. As of December 31, 2024 and December 31, 2023, production cost of contracts were $6.8 
million and $7.8 million, respectively.
Contract Assets and Contract Liabilities
Contract assets consist of our right to payment for work performed but not yet billed. Contract assets are transferred to 
accounts receivable when we bill our customers. We bill our customers when we ship the products and meet the shipping 
terms within the revenue contract. Contract liabilities consist of advance or progress payments received from our customers 
prior to the time transfer of control occurs plus the estimated losses on contracts. When a contract liability and a contract 
asset exist on the same contract, we report it on a net basis.
Contract assets and contract liabilities from revenue contracts with customers are as follows:

The increase in our contract assets as of December 31, 2024 compared to December 31, 2023 was primarily due to a net 
increase of products in work in process.
The decrease in our contract liabilities as of December 31, 2024 compared to December 31, 2023 was primarily due to a net 
decrease of advance or progress payments received from our customers in the current year. We recognized $37.9 million of 
the contract liabilities as of December 31, 2023 as revenues during the year ended December 31, 2024.
Performance obligations are defined as customer placed purchase orders (“POs”) with firm fixed price and firm delivery 
dates. Our remaining performance obligations as of December 31, 2024 totaled $1,012.6 million. We anticipate recognizing 
an estimated 70% of our remaining performance obligations as revenue during the next 12 months with the remaining 
performance obligations being recognized in 2026 and beyond.

Income Taxes
Income taxes are accounted for using an asset and liability approach that requires the recognition of deferred tax assets and 
liabilities. Deferred tax assets and liabilities are recognized, using enacted tax rates, for the expected future tax consequences 
of temporary differences between the book and tax bases of recorded assets and liabilities, operating losses, and tax credit 
carryforwards. Deferred tax assets are evaluated quarterly and are reduced by a valuation allowance if it is more likely than 
not that some portion or all of the deferred tax assets will not be realized.
Tax positions taken or expected to be taken in a tax return are recognized when it is more-likely-than-not, based on technical 
merits, to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of 
benefit that is greater than 50% likely of being realized upon ultimate settlement, including resolution of related appeals and/
or litigation process, if any.
Litigation and Commitments
In the normal course of business, we are defendants in certain litigation, claims and inquiries, including matters relating to 
environmental laws. In addition, we make various commitments and incur contingent liabilities. Management’s estimates 
regarding contingent liabilities could differ from actual results.
Environmental Liabilities
Environmental liabilities are recorded when environmental assessments and/or remedial efforts are probable and costs can be 
reasonably estimated. Generally, the timing of these accruals coincides with the completion of a feasibility study or our 
commitment to a formal plan of action. Further, we review and update our environmental accruals as circumstances change 
and/or additional information is obtained that reasonably could be expected to have a meaningful effect on the outcome of a 
matter or the estimated cost thereof.
Accounting for Stock-Based Compensation
We measure and recognize compensation expense for share-based payment transactions to our employees and non-employees 
at their estimated fair value. The expense is measured at the grant date, based on the calculated fair value of the share-based 
award, and is recognized over the requisite service period (generally the vesting period of the equity award). The fair value of 
Table of Contents
59
59

stock options is determined using the Black-Scholes-Merton (“Black-Scholes”) valuation model, which requires assumptions 
and judgments regarding stock price volatility, risk-free interest rates, and expected options terms. Management’s estimates 
could differ from actual results. The fair value of unvested stock awards is determined based on the closing price of the 
underlying common stock on the date of grant except for market condition awards for which the fair value was based on a 
Monte Carlo simulation model. 
Charitable Contributions
We contributed $0.1 million to the Ducommun Foundation during 2024.
Earnings Per Share
Basic earnings per share are computed by dividing income available to common shareholders by the weighted-average 
number of common shares outstanding in each period. Diluted earnings per share is computed by dividing income available 
to common shareholders by the weighted-average number of common shares outstanding, plus potentially dilutive shares that 
could be issued if exercised or converted into common stock in each period.
The net income and weighted-average common shares outstanding used to compute earnings per share were as follows:

Recent Accounting Pronouncements
New Accounting Guidance Adopted in 2024 
In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 
2023-07, “Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which 
expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment 
expenses. The new guidance is effective for fiscal years beginning after December 15, 2023, which is our annual period 
beginning January 1, 2024, and interim periods within fiscal years beginning after December 15, 2024, which will be our 
interim period beginning January 1, 2025. The adoption of ASU 2023-07 did not have a material impact on our consolidated 
financial statements. See Note 18 for the enhanced disclosures.
Recently Issued Accounting Standards
In January 2025, the FASB issued ASU 2025-01, “Income Statement - Reporting Comprehensive Income - Expense 
Disaggregation Disclosures (Subtopic 220-40):  Clarifying the Effective Date” (“ASU 2025-01”), which clarifies that all 
public business entities should initially adopt the disclosure requirements in the final annual reporting period beginning after 
December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The

new guidance is effective for fiscal years beginning after December 15, 2026, which is our annual period beginning January 
1, 2027, and interim reporting periods beginning after December 15, 2027, which will be our interim period beginning 
January 1, 2028. Early adoption of ASU 2024-03 (described below) is permitted. We are evaluating the impact of this 
standard in conjunction with ASU 2024-03.
In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense 
Disaggregation Disclosures (Subtopic 220-40):  Disaggregation of Income Statement Expenses” (“ASU 2024-03”), which 
requires additional information about specific expense categories in the notes to the financial statements at interim and annual 
reporting periods. The new guidance is effective for fiscal years beginning after December 15, 2026, which is our annual 
period beginning January 1, 2027, and interim reporting periods beginning after December 15, 2027, which will be our 
interim period beginning January 1, 2028. Early adoption is permitted. The amendments in ASU 2024-03 should be applied 
either 1) prospectively to financial statements issued for reporting periods after the effective date, or 2) retrospectively to any 
or all prior periods presented in the financial statements. We are evaluating the impact of this standard.
In March 2024, the FASB issued ASU 2024-02, “Codification Improvements - Amendments to Remove References to the 
Concepts Statements” (“ASU 2024-02”), which removed references to various FASB Concepts Statements and updates 
technical corrections such as conforming amendments, clarification to guidance, simplifications to wording or the structure of 
guidance, and other minor improvements. The new guidance is effective for fiscal years beginning after December 15, 2024, 
which is our annual period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this 
standard.
In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740):  Improvements to Income Tax 
Disclosures” (“ASU 2023-09”), which provides more transparency about tax information primarily related to the rate 
reconciliation and the income taxes paid. The new guidance is effective for fiscal years beginning after December 15, 2024, 
which will be our annual period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this 
standard.
In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements:  Codification Amendments in Response to the 
SEC’s Disclosure Update and Simplification Initiative” (“ASU 2023-06”), which incorporates updates to the Accounting 
Standards Codification to align certain SEC disclosure requirements. The amendments impact a variety of topics but are 
relatively narrow in nature. For entities required to comply with the SEC’s existing disclosure requirements, the effective date 
for each amendment will be the effective date of the removal of the disclosure requirement from SEC Regulation S-X or SEC 
Regulation S-K, with early adoption prohibited. The amendments should be applied prospectively. We are evaluating the 
impact of this standard.
 
Note 2. Business Combinations
In April 2023, we acquired 100.0% of the outstanding equity interests of BLR Aerospace, L.L.C. (“BLR”), a privately-held 
leading provider of aerodynamic systems that enhance the productivity, performance, and safety of rotary and fixed-wing 
aircraft on commercial and military platforms. BLR is located in Everett, Washington. The acquisition of BLR added to our 
strategy to diversify and offer more customized, value-driven engineered products with aftermarket opportunities. 
The initial purchase price for BLR was $115.0 million, net of cash acquired, all payable in cash, subject to adjustments for 
working capital. We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. Subsequent to the 
closing of the transaction, during the third quarter of 2023, the working capital was finalized and the impact was immaterial 
for a final purchase price of $114.4 million, net of cash acquired. We allocated the gross purchase price of $117.0 million to 
the assets acquired and liabilities assumed at their estimated fair values. The excess of the purchase price over the aggregate 
fair values of the net assets was recorded as goodwill.
The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of 
acquisition (in thousands):

The intangible assets acquired of $55.5 million were determined based on the estimated fair values using valuation techniques 
consistent with the income approach to measure fair value, which represented Level 3 fair value measurements. The useful 
lives were estimated based on the underlying agreements or the future economic benefit expected to be received from the 
assets. The values for technology and trade name were assessed using the relief from royalty methodology, while the value 
for customer relationships was estimated based on a multi-period excess earnings approach. Inputs to the income approach 
models and other aspects of the allocation of the purchase price require judgment. The more significant inputs used in the 
technology intangible asset valuation included (i) future revenues, (ii) the technology decay rate (iii) the royalty rate, and (iv) 
the discount rate. The more significant inputs used in the customer relationships intangible asset valuation included (i) future 
revenues, (ii) the projected earnings before interest, taxes, and amortization (“EBITA”) margins, (iii) the customer attrition 
rates, and (iv) the discount rate.
The goodwill of $41.2 million arising from the acquisition is attributable to the benefits we expect to derive from expected 
synergies from the transaction, including complementary products that will enhance our overall product portfolio, 
opportunities within new markets, and an acquired assembled workforce. All the goodwill was assigned to the Structural 
Systems segment. The BLR acquisition, for tax purposes, is deemed an asset acquisition and thus, the goodwill recognized is 
deductible for income tax purposes.
Acquisition related transaction costs were not included as components of consideration transferred but have been expensed as 
incurred. Total acquisition-related transaction costs incurred by us were $1.3 million during 2023 and charged to selling, 
general and administrative expenses. 
BLR’s results of operations have been included in our consolidated statements of income since the date of acquisition as part 
of the Structural Systems segment and were less than three percent of total company revenues since the date of acquisition. 
Pro forma results of operations of the BLR acquisition have not been presented as the effect of the BLR acquisition was not 
material to our financial results.

Note 3. Restructuring Activities
Summary of 2022 Restructuring Plan
In April 2022, management approved and commenced a restructuring plan that will better position us for stronger 
performance. The restructuring plan mainly reduces headcount and consolidates facilities. As a result of this restructuring 
plan, we analyzed the need to write-down inventory and impair long-lived assets, including operating lease right-of-use 
assets. During the year ended December 31, 2024, we recorded total charges of $7.7 million. Cumulative through the year 
ended December 31, 2024, we recorded total charges of $29.2 million. As of December 31, 2024, we estimate the remaining 
amount of charges related to this initiative will be $1.0 million to $1.5 million in total pre-tax restructuring charges through 
2025 for facility consolidation related expenses. 
In the Electronics Systems segment, we recorded (credits) charges of $(0.1) million, zero, and $0.2 million during the year 
ended December 31, 2024, for severance and benefits that were classified as restructuring charges, charges for inventory 
write down that were classified as cost of sales, and other restructuring, respectively. Cumulative through the year ended 
December 31, 2024, we recorded total charges for severance and benefits that were classified as restructuring charges, 
accelerated depreciation of property and equipment that was classified as restructuring charges, charges for inventory write 
down that were classified as cost of sales, and other restructuring of $9.5 million, $0.3 million, $0.3 million, and $0.2 million, 
respectively.
In the Structural Systems segment, we recorded $1.7 million, zero, $1.2 million, and $4.6 million during the year ended 
December 31, 2024 for severance and benefits that were classified as restructuring charges, accelerated depreciation of 
property and equipment that was classified as restructuring charges, charges for inventory write down that was classified as 
cost of sales, and other restructuring charges, respectively. Cumulative through the year ended December 31, 2024, we 
recorded total charges for severance and benefits that were classified as restructuring charges, accelerated depreciation of 
property and equipment that was classified as restructuring charges, impairment of property and equipment that was 
classified as restructuring charges, charges for inventory write down that was classified as cost of sales, and other 
restructuring of $7.6 million, $1.7 million, $0.3 million, $1.8 million, and $7.4 million, respectively.

Note 7. Leases
All Leases
We elected to utilize the following practical expedients that are permitted under ASC 842:
•
As an accounting policy election by class of underlying asset, elected not to separate nonlease components from 
lease components and instead to account for each separate lease component and the nonlease components associated 
with that lease component as a single lease component; and
•
As an accounting policy election not to apply the recognition requirements in ASC 842 to short term leases (a lease 
at commencement date has a lease term of 12 months or less and does not contain a purchase option that the lessee is 
reasonably certain to exercise).
We have operating and finance leases for manufacturing facilities, corporate offices, and various equipment. Our leases have 
remaining lease terms of 1 to 9 years, some of which include options to extend the leases for up to 15 years, and some of 
which include options to terminate the leases within 1 year.
The components of lease expense consisted of the following:

When a lease is identified, we recognize a right-of-use asset and a corresponding lease liability based on the present value of 
the lease payments over the lease term discounted using our incremental borrowing rate, unless an implicit rate is readily 
determinable. As the discount rate in our leases is usually not readily available, we use our own incremental borrowing rate as 
the discount rate. Our incremental borrowing rate is based on the interest rate on our term loan, which is a secured rate. After 
we completed a financing of all our existing debt in July 2022, the interest rate on our term loan was based on Term Secured 
Overnight Financing Rate (“Term SOFR”) plus an applicable margin. Prior to the refinancing, the interest rate on our term 
loans were based on London Interbank Offered Rate (“LIBOR”) plus an applicable margin.

We perform our annual goodwill impairment test as of the first day of the fourth quarter. If certain factors occur, including 
significant under performance of our business relative to expected operating results, significant adverse economic and 
industry trends, significant decline in our market capitalization for an extended period of time relative to net book value, a 
decision to divest individual businesses within a reporting unit, or a decision to group individual businesses differently, we 
may be required to perform an interim impairment test prior to the fourth quarter. 
We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment. The 
qualitative approach for potential impairment analysis is performed by evaluating a number of qualitative factors to determine 
whether it is more likely than not that the fair value of a reporting unit was less than its carrying amount. If the qualitative 
assessment indicates that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, we 
perform a quantitative assessment.
The quantitative approach for potential impairment analysis is performed by comparing the fair value of a reporting unit to its 
carrying value, including goodwill. Fair value is estimated by management using a combination of the income approach 
(which is based on a discounted cash flow model) and market approach. Management’s cash flow projections include 
significant judgments and assumptions, including the amount and timing of expected cash flows, long-term growth rates, and 
discount rates. The cash flows used in the discounted cash flow model are based on our best estimate of future revenues, 
gross margins, and adjusted after-tax earnings. If any of these assumptions are incorrect, it will impact the estimated fair 
value of a reporting unit. The market approach also requires management judgment in selecting comparable companies, 
business acquisitions and the transaction values observed and its related control premiums.
As of the first day of the fourth quarter of 2024, we performed a quantitative goodwill impairment test for both our Electronic 
Systems and Structural Systems reporting units. Based on the results of this test, the fair values of both reporting units 
exceeded their respective carrying values. Thus, the respective goodwill amounts were not deemed impaired.
In April 2023, we completed the acquisition of BLR. The excess of the purchase price over the aggregate fair values of the 
net assets was recorded as goodwill. See Note 2 for further information.
Other Intangible Assets
Other intangible assets are related to acquisitions, including BLR, and recorded at fair value at the time of the acquisition. 
Other intangible assets with finite lives are generally amortized on the straight-line method over periods ranging from 2 to 23

In July 2022, we completed a refinancing of all our existing debt by entering into a new term loan (“2022 Term Loan”) and a 
new revolving credit facility (“2022 Revolving Credit Facility”). The 2022 Term Loan is a $250.0 million senior secured loan 
that matures on July 14, 2027. The 2022 Revolving Credit Facility is a $200.0 million senior secured revolving credit facility 
that matures on July 14, 2027. The 2022 Term Loan and 2022 Revolving Credit Facility, collectively are the new credit 
facilities (“2022 Credit Facilities”).
The 2022 Term Loan bears interest, at our option, at a rate equal to either (i) Term Secured Overnight Financing Rate (“Term 
SOFR”) plus an applicable margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] 
Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is 
less than zero percent, it will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in 
each case based upon the consolidated total net adjusted leverage ratio. Interest payments are typically paid either on a 
monthly or quarterly basis, depending on the interest rate selected, on the last business day each month or quarter. In addition, 
the 2022 Term Loan requires quarterly amortization payments of 0.625% during year one and year two, 1.250% during year

three and year four, and 1.875% during year five of the original outstanding principal balance of the 2022 Term Loan 
amount, on the last business day each quarter. The first quarterly amortization payment of $1.6 million was required to be 
paid and was paid during the fourth quarter of 2022. We made the required quarterly amortization payments totaling 
$7.8 million and $6.3 million during the years ended December 31, 2024 and 2023, respectively.
The 2022 Revolving Credit Facility bears interest, at our option, at a rate equal to either (i) Term SOFR plus an applicable 
margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] Federal Funds Rate plus 
0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is less than zero percent, it 
will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in each case based upon the 
consolidated total net adjusted leverage ratio. Interest payments are typically paid either on a monthly or a quarterly basis, 
depending on the interest rate selected, on the last business day each month or quarter. The undrawn portion of the 
commitment of the 2022 Revolving Credit Facility is subject to a commitment fee ranging from 0.175% to 0.275%, based 
upon the consolidated total net adjusted leverage ratio, typically paid on a quarterly basis, on the last business day each 
quarter. However, the 2022 Revolving Credit Facility does not require any principal installment payments.
In conjunction with the closing of the 2022 Credit Facilities, we utilized the entire $250.0 million of proceeds from the 2022 
Term Loan plus our existing cash on hand to pay off our entire debt balance outstanding of $254.2 million under prior credit 
facilities (described below).
In December 2019, we completed the refinancing of a portion of our then existing debt by entering into a new revolving 
credit facility (“2019 Revolving Credit Facility”) to replace the then existing revolving credit facility that was entered into in 
November 2018 (“2018 Revolving Credit Facility”) and entered into a new term loan (“2019 Term Loan”). The 2019 
Revolving Credit Facility was a $100.0 million senior secured revolving credit facility that would have matured on December 
20, 2024 and replaced the $100.0 million 2018 Revolving Credit Facility that would have matured on November 21, 2023. 
The 2019 Term Loan was a $140.0 million senior secured term loan that would have matured on December 20, 2024. We 
also had a then existing $240.0 million senior secured term loan that was entered into in November 2018 that would have 
matured on November 21, 2025 (“2018 Term Loan”). The original amounts available under the 2019 Revolving Credit 
Facility, 2019 Term Loan, and 2018 Term Loan (collectively, the “Existing Credit Facilities”) in aggregate, totaled $480.0 
million at that time. 
The 2019 Term Loan bore interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as the London 
Interbank Offered Rate [“LIBOR”]) plus an applicable margin ranging from 1.50% to 2.50% per year or (ii) the Base Rate 
(defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate 
plus 1.00%) plus an applicable margin ranging from 0.50% to 1.50% per year, in each case based upon the consolidated total 
net adjusted leverage ratio, typically payable quarterly. In addition, the 2019 Term Loan required amortization payments of 
1.25% of the original outstanding principal balance of the 2019 Term Loan amount on a quarterly basis, on the last day of the 
calendar quarter. During 2022, we made the required quarterly payments on the 2019 Term Loan before it was refinanced, in 
aggregate totaling $3.5 million.
The 2019 Revolving Credit Facility bore interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as 
LIBOR) plus an applicable margin ranging from 1.50% to 2.50% per year or (ii) the Base Rate (defined as the highest of [a] 
Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate plus 1.00%) plus an applicable 
margin ranging from 0.50% to 1.50% per year, in each case based upon the consolidated total net adjusted leverage ratio, 
typically payable quarterly. The undrawn portion of the commitment of the 2019 Revolving Credit Facility was subject to a 
commitment fee ranging from 0.175% to 0.275%, based upon the consolidated total net adjusted leverage ratio. However, the 
2019 Revolving Credit Facility did not require any principal installment payments.
The 2018 Term Loan bore interest, at our option, at a rate equal to either (i) the Eurodollar Rate (defined as LIBOR plus an 
applicable margin ranging from 3.75% to 4.00% per year or (ii) the Base Rate (defined as the highest of [a] Federal Funds 
Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] the Eurodollar Rate plus 1.00%) plus an applicable margin 
ranging from 3.75% to 4.00% per year, in each case based upon the consolidated total net adjusted leverage ratio, typically 
payable quarterly. In addition, the 2018 Term Loan required amortization payments of 0.25% of the outstanding principal 
balance of the 2018 Term Loan amount on a quarterly basis. 
Further, under the then Existing Credit Facilities, if we exceeded the annual excess cash flow threshold, we were required to 
make an annual additional principal payment based on the consolidated adjusted leverage ratio. The annual mandatory excess 
cash flow payment was based on (i) 50% of the excess cash flow amount if the adjusted leverage ratio is greater than 3.25 to 
1.0, (ii) 25% of the excess cash flow amount if the adjusted leverage ratio was less than or equal to 3.25 to 1.0 but greater 
Table of Contents
70
70

than 2.50 to 1.0, and (iii) zero percent of the excess cash flow amount if the consolidated adjusted leverage ratio was less than 
or equal to 2.50 to 1.0. We did not exceed the annual excess cash flow threshold for 2021 and thus, no annual excess cash 
flow payment was required to be paid during the first quarter of 2022. 
In addition, since we were paying down on the term loans during the first quarter of 2022, we were required to pay down on 
the 2019 Term Loan and 2018 Term Loan on a pro-rata basis and thus, we paid down $13.0 million and $17.0 million on the 
2019 Term Loan and 2018 Term Loan, respectively, for an aggregate total pay down of $30.0 million.
As of December 31, 2024, we had $191.0 million of unused borrowing capacity under the 2022 Revolving Credit Facility, 
after deducting $0.2 million for standby letters of credit.
As of December 31, 2024, we were in compliance with all covenants required under the 2022 Credit Facilities. 
The 2022 Term Loan was considered a modification of debt for some lenders and an extinguishment of debt for other lenders, 
and thus, a loss of $0.2 million was recorded related to the extinguishment. In addition, the new fees incurred of $0.8 million 
were capitalized and will be amortized to interest expense over the life of the 2022 Term Loan. Further, the remaining debt 
issuance costs related to the 2019 Term Loan and 2018 Term Loan of $1.0 million as of the modification date will be 
amortized to interest expense over the life of the 2022 Term Loan, using the effective interest method.
The 2022 Revolving Credit Facility that replaced the 2019 Revolving Credit Facility was considered a modification of debt 
except for the portion related to the creditor that is no longer a part of the 2022 Revolving Credit Facility and in which case, it 
was considered an extinguishment of debt. As a result, we expensed the portion of the unamortized debt issuance costs 
related to the 2019 Revolving Credit Facility that was considered an extinguishment of debt of $0.1 million. In addition, the 
new fees incurred of $1.7 million as part of the 2022 Revolving Credit Facility were capitalized and will be amortized to 
interest expense over the life of the 2022 Revolving Credit Facility. Further, the remaining debt issuance costs related to the 
2019 Revolving Credit Facility of $0.8 million as of the modification date will also be amortized to interest expense over the 
life of the 2022 Revolving Credit Facility.
The 2022 Credit Facilities were entered into by us (“Parent Company”) and guaranteed by all of our domestic subsidiaries, 
other than two subsidiaries that were considered minor (“Subsidiary Guarantors”). The Subsidiary Guarantors jointly and 
severally guarantee the 2022 Credit Facilities. The Parent Company has no independent assets or operations and therefore, no 
consolidating financial information for the Parent Company and its subsidiaries is presented.
In April 2023, we completed the acquisition of BLR. The initial purchase price for BLR was $115.0 million, net of cash 
acquired, all payable in cash. We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. We 
utilized the 2022 Revolving Credit Facility to complete the acquisition. See Note 2.
In May 2023, we completed a public offering of our common stock resulting in net proceeds of $85.1 million. We utilized the 
net proceeds plus cash on hand to pay down $85.2 million on the 2022 Revolving Credit Facility. See Note 11 for further 
information.
In November 2021, we entered into derivative contracts, U.S. dollar-one month LIBOR forward interest rate swaps 
designated as cash flow hedges, all with an effective date of January 1, 2024, for an aggregate total notional amount of 
$150.0 million, weighted average fixed rate of 1.8%, and all terminating on January 1, 2031 (“Forward Interest Rate Swaps”). 
The Forward Interest Rate Swaps mature on a monthly basis, with fixed amount payer payment dates on the first day of each 
calendar month, commencing on February 1, 2024 through January 1, 2031. The Forward Interest Rate Swaps were deemed 
to be highly effective upon entering into the derivative contracts and thus, hedge accounting treatment was utilized. Since the 
Amended Forward Interest Rate Swaps (as defined below) were not effective until January 1, 2024, we only record the 
changes in the fair value of the derivative instruments that were highly effective and that were designated and qualified as 
cash flow hedges in other comprehensive income through December 31, 2023. See Note 1 and Note 4 for further information.
In July 2022, as a result of completing a refinancing of our existing debt, we were required to complete an amendment of the 
Forward Interest Rate Swaps (“Amended Forward Interest Rate Swaps”). The Forward Interest Rate Swaps were based on 
U.S. dollar-one month LIBOR and were amended to be based on one month Term SOFR as borrowings using LIBOR are no 
longer available under the 2022 Credit Facilities. Since this was an amendment of just the reference rate as a result of the 
cessation of LIBOR, utilizing the guidance under ASU 2020-04, we determined the Amended Forward Interest Rate Swaps 
as of the amendment date to continue to be highly effective. The Amended Forward Interest Rate Swaps weighted average 
fixed rate was 1.7% as a result of the difference between U.S. dollar-one month LIBOR and one month Term SOFR.

Note 11. Shareholders’ Equity
In May 2023, we completed a public offering of 2.3 million shares of our common stock at $40.00 per share, for gross 
proceeds of $92.0 million. The common stock offering was made under our effective shelf registration statement. We 
incurred aggregate total out of pocket stock offering related fees of $6.9 million, resulting in net proceeds of $85.1 million. 
As such, we recorded an increase to common stock at par value of less than $0.1 million with the remaining amount as an 
increase to additional paid-in capital of $85.1 million. The public stock offering net proceeds along with cash on hand were 
used to pay down $85.2 million on the 2022 Revolving Credit Facility that was drawn on and utilized to complete the 
acquisition of BLR. See Note 2 and Note 10 for further information.
We are authorized to issue five million shares of preferred stock. At December 31, 2024 and 2023, no preferred shares were 
issued or outstanding.
Note 12. Stock-Based Compensation
Stock Incentive Compensation Plans
We currently have two active stock incentive plans: i) the 2024 Stock Incentive Plan (the “2024 Plan”), which expires on 
April 24, 2034, and ii) the 2018 Employee Stock Purchase Plan (“ESPP”). The Amended and Restated 2020 Stock Incentive 
Plan (the “2020 Plan”) was closed to further issuances of stock awards on April 24, 2024 and any remaining shares available 
were folded into the 2024 Plan as part of the approval of the 2024 Plan by shareholders at the 2024 Annual Meeting of 
Shareholders in April 2024. The 2024 Plan permit awards of stock options, restricted stock units, performance stock units and 
other stock-based awards to our officers, key employees and non-employee directors on terms determined by the 
Compensation Committee of the Board of Directors (the “Compensation Committee”). The aggregate number of shares 
available for issuance under the 2024 Plan is 745,377 plus any outstanding awards issued under the 2020 Plan that are 
subsequently forfeited, terminated, expire or otherwise lapse without being exercised. As of December 31, 2024, shares 
available for future grant under the 2024 Plan are 499,523. Prior to the adoption of the 2024 Plan, we granted stock-based 
awards to purchase shares of our common stock under certain predecessor plans. No further awards can be granted under 
these predecessor plans.
Employee Stock Purchase Plan
The ESPP was adopted by the Board of Directors and approved by the shareholders in 2018, including 750,000 shares that 
can be awarded. The first offering period closed on July 31, 2019. Under the ESPP, our employees who elect to participate 
have the right to purchase common stock at a 15% discount from the lower of the market value of the common stock at the 
beginning or the end of each six month offering period and the discount will be treated as compensation to those employees. 
Employees purchase common stock using payroll deductions, which may not exceed 10% of their eligible compensation and 
other limitations. The Compensation Committee administers the ESPP. As of December 31, 2024, there are 442,546 shares 
available for future award grants.
Stock Options
In the years ended December 31, 2024, 2023, and 2022, we did not grant any stock options to our officers and key employees 
nor were any stock options, stock appreciation rights or other option-like instruments granted to our directors or officers 
within four days prior to, or one day after the release of material non-public information. Stock options are typically granted 
with an exercise price equal to the fair market value of our stock on the date of grant and expire not more than ten years from 
the date of grant. The stock options typically vest over a period of three or four years from the date of grant. The option price 
and number of shares are subject to adjustment under certain dilutive circumstances. If an employee terminates employment, 
the non-vested portion of the stock options will not vest and all rights to the non-vested portion will terminate completely.

All stock options outstanding as of January 1, 2024 were fully vested.
The aggregate intrinsic value of stock options represents the amount by which the market price of our common stock exceeds 
the exercise price of the stock option. The aggregate intrinsic value of stock options exercised for the years ended 
December 31, 2024, 2023 and 2022 was $0.4 million, $1.0 million, and $2.0 million, respectively. Cash received from stock 
options exercised for the years ended December 31, 2024, 2023 and 2022 was $0.8 million, $1.6 million, and $3.5 million, 
respectively, with related tax benefits of $0.2 million, $0.4 million, and $0.8 million, respectively. The total amount of stock 
options vested is 114,270 shares with a weighted-average exercise price of $38.93 and an aggregate intrinsic value of $2.8 
million. There were no unvested stock options as of December 31, 2024. These stock options have a weighted-average 
remaining contractual term of 4.1 years.
The share-based compensation cost expensed for stock options for the years ended December 31, 2024, 2023, and 2022 
(before tax benefits) was zero, zero, and $0.3 million, respectively, and is included in selling, general and administrative 
expenses on the consolidated income statements. At December 31, 2024, there were no remaining unrecognized 
compensation cost related to stock options. The total fair value of stock options vested during the years ended December 31, 
2024, 2023, and 2022 was zero, zero, and $0.8 million, respectively.
We typically apply fair value accounting for stock-based compensation based on the grant date fair value estimated using a 
Black-Scholes-Merton (“Black-Scholes”) valuation model. There were no stock options granted under the 2024 Plan or the 
2020 Plan for the years ended December 31, 2024, 2023, and 2022.
We recognize compensation expense, net of an estimated forfeiture rate, on a straight-line basis over the requisite service 
period of the award. We have award populations with option vesting terms of three and four years. We estimate the forfeiture 
rate based on our historic experience, attempting to determine any discernible activity patterns. The expected life computation 
is based on historic exercise patterns and post-vesting termination behavior. The risk-free interest rate for periods within the 
contractual life of the award is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is 
derived from historical volatility of our common stock. We suspended payments of dividends after the first quarter of 2011.
Restricted Stock Units
We granted restricted stock units (“RSUs”) to certain officers, key employees and non-employee directors of 144,775, 
110,067, and 118,847 RSUs during the years ended December 31, 2024, 2023, and 2022, respectively, with weighted-average 
grant date fair values (equal to the fair market value of our stock on the date of grant) of $56.43, $51.57, and $51.76 per 
share, respectively. RSUs represent a right to receive a share of stock at future vesting dates with no cash payment required 
from the holder. The RSUs typically have a three year vesting term of 33.3%, 33.3% and 33.4% on the first, second and third 
anniversaries of the date of grant, respectively. If an employee terminates employment, their non-vested portion of the RSUs 
will not vest and all rights to the non-vested portion will terminate.

expenses on the consolidated income statements. At December 31, 2024, total unrecognized compensation cost (before tax 
benefits) related to RSUs of $7.7 million is expected to be recognized over a weighted average period of 1.7 years. The total 
fair value of RSUs vested for the years ended December 31, 2024, 2023, and 2022 was $4.8 million, $3.9 million, and $3.5 
million, respectively. The tax benefit realized from vested RSUs for the years ended December 31, 2024, 2023, and 2022 was 
$1.1 million, $0.9 million, and $0.8 million, respectively.
Performance Stock Units
We granted performance stock awards (“PSUs”) to certain key employees of 156,565, 160,852, and 111,654 PSUs during the 
years ended December 31, 2024, 2023, and 2022, respectively, with weighted-average grant date fair values of $63.45, 
$40.51, and $48.18 per share, respectively. PSU awards are subject to the attainment of performance goals established by the 
Compensation Committee, the periods during which performance is to be measured, and all other limitations and conditions 
applicable to the awarded shares. Performance goals are based on a pre-established objective formula that specifies the 
manner of determining the number of PSUs that will be granted if performance goals are attained. If an employee terminates 
employment, their non-vested portion of the PSUs will not vest and all rights to the non-vested portion will terminate.

Performance-Based With Market Condition Cash Settled Long-Term Incentive Awards
As permitted under the 2020 Plan, performance-based with market condition cash settled long-term incentive awards 
(“Performance-Based Cash LTIPs”) were granted in 2023 and 2022. Performance-Based Cash LTIPs will be settled in cash 
and are subject to the attainment of performance goals established by the Compensation Committee (including achievement 
of relative total shareholder return market condition), the periods during which performance is to be measured, and all other 
limitations and conditions applicable to the Performance-Based Cash LTIPs’ values. Performance goals are based on a pre-
established objective formula that specifies the manner of determining the value of the Performance-Based Cash LTIPs that

will be issued if performance goals are attained. If an employee terminates employment, their non-vested portion of the 
Performance-Based Cash LTIPs will not vest and all rights to the non-vested portion of the Performance-Based Cash LTIPs 
will terminate. The Compensation Committee administers the Performance-Based Cash LTIPs. The share-based 
compensation expense recorded for the Performance-Based Cash LTIPs for the years ended December 31, 2024, 2023, and 
2022 (before tax benefits) was $3.7 million, $2.7 million, and $1.2 million, respectively.
Note 13. Employee Benefit Plans
Defined Contribution 401(k) Plans
We sponsor a 401(k) defined contribution plan for all our employees. The plan allows the employees to make annual 
voluntary contributions not to exceed the lesser of an amount equal to 25% of their compensation or limits established by the 
Internal Revenue Code. Under this plan, we generally provide a match equal to 50% of the employee’s contributions up to the 
first 6% of compensation, except for union employees who are not eligible to receive the match. Our provision for matching 
and profit sharing contributions for the three years ended December 31, 2024, 2023, and 2022 was $3.2 million, $3.1 million, 
and $2.9 million, respectively.
Pension Plan and LaBarge Retirement Plan
We have a defined benefit pension plan covering certain hourly employees of a subsidiary (the “Pension Plan”). Pension Plan 
benefits are generally determined on the basis of the retiree’s age and length of service. Assets of the Pension Plan are 
composed primarily of fixed income and equity securities. We also have a retirement plan covering certain current and retired 
employees (the “LaBarge Retirement Plan”). 
The consolidation of one of our performance centers as part of the 2022 Restructuring Plan as discussed in Note 3 resulted in 
the curtailment of the Pension Plan during the fourth quarter of 2022, but it had an immaterial impact on our consolidated 
financial statements.

(1) Projected benefit obligation equals the accumulated benefit obligation for the plans.
On December 31, 2024, our annual measurement date, the accumulated benefit obligation exceeded the fair value of the plans 
assets by $0.4 million. Such excess is referred to as an unfunded accumulated benefit obligation. We recorded an 
unrecognized loss included in accumulated other comprehensive income, net of tax at December 31, 2024 and 2023 of $2.2 
million and $4.2 million, respectively, which decreased shareholders’ equity. This charge to shareholders’ equity represents a 
net loss not yet recognized as pension expense. This charge did not affect reported earnings, and would be decreased or be 
eliminated if either interest rates increase or market performance and plan returns improve which will cause the Pension Plan 
to return to fully funded status.
Our Pension Plan asset allocations at December 31, 2024 and 2023, by asset category, were as follows:

The Pension Plan is associated with the union employees at one of the performance centers that ceased operations in 2024 as 
a result of the 2022 Restructure Plan. Therefore, during 2023, we changed the overall investment strategy to achieve an asset 
allocation that de-risked the investment portfolio to preserve capital as the Pension Plan was fully funded. As of 
December 31, 2024, the Pension Plan assets consists primarily of bonds and cash and cash equivalents. The return on assets 
assumption reflects the average rate of return expected on the bonds and cash and cash equivalents invested to provide for the 
benefits included in the projected benefit obligation. We consider information from various external investment managers, 
forward-looking information regarding expected returns by asset class and our own judgment when determining the expected 
returns.

The assumptions used to determine the benefit obligations and expense for our two plans are presented in the tables below. 
The expected long-term return on assets, noted below, represents an estimate of long-term returns on investment portfolios 
consisting of a mixture of fixed income and cash and cash equivalents. The estimated cash flows from the plans for all future 
years are determined based on the plans’ population at the measurement date. We used the expected benefit payouts from the 
plans for each year into the future and discounted them back to the present using the USI Consulting Group (“USICG”) yield 
curve rate for that duration.
The weighted-average assumptions used to determine the net periodic benefit costs under the two plans were as follows:

Our funding policy is to contribute cash to our plans so that the minimum contribution requirements established by 
government funding and taxing authorities are met. We expect to make contributions of $0.4 million to the plans in 2025.
Supplemental Retirement Plans
We have three unfunded supplemental retirement plans. The first plan (“First Plan”) was suspended in 1986, but continues to 
cover certain former executives. The second plan (“Second Plan”) was suspended in 1997, but continues to cover certain 
current and retired directors. The third plan (“Third Plan”) covers certain current and retired employees and further employee 
contributions to this plan were suspended on August 5, 2011. The liability for the First and Third Plans and interest thereon 
was zero at December 31, 2024 and December 31, 2023. The accumulated benefit obligations of the Second Plan at 
December 31, 2024 and December 31, 2023 were both $0.3 million, and are included in accrued liabilities.
Non-Qualified Deferred Compensation Plan
In 2019, we adopted a nonqualified deferred compensation plan (“NQDC Plan”) that allows certain management employees 
or independent contractors to elect deferral of receipt of compensation from Ducommun in order to provide retirement and 
other benefits on behalf of such management employees or independent contractors (“Certain Participants”). The NQDC Plan 
is intended to be a nonqualified deferred compensation plan that complies with the provisions of Section 409A of the Internal 
Revenue Code (the “Code”). The NQDC Plan is also intended to be an unfunded plan maintained primarily for the purpose of 
providing deferred compensation benefits for a select group of management or highly compensated employees under Section 
201(2), 301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act of 1974 (“ERISA”) and independent 
contractors. Notwithstanding any other provision of this NQDC Plan, this NQDC Plan will be interpreted, operated and 
administered in a manner consistent with these intentions. The Certain Participants’ assets will not be dispensed until the 
occurrence of a qualified distribution event. The total liabilities at December 31, 2024 and December 31, 2023 were 
$2.3 million and $1.9 million, respectively, and are included in other long term liabilities.
 
Note 14. Indemnifications
We have made guarantees and indemnities under which we may be required to make payments to a guaranteed or 
indemnified party, in relation to certain transactions, including revenue transactions in the ordinary course of business. 
Additionally, we indemnify our directors and officers to the maximum extent permitted under the laws of the State of 
Delaware and have a directors and officers insurance policy that may reduce our exposure in certain circumstances and may 
enable us to recover a portion of future amounts that may be payable, if any. Moreover, in connection with certain 
performance center leases, we have indemnified our lessors for certain claims arising from the performance center or the 
lease.

The duration of the guarantees and indemnities varies and in many cases is indefinite but subject to applicable statutes of 
limitations. The majority of guarantees and indemnities do not provide any limitations on the maximum potential future 
payments we could be obligated to make. Historically, payments related to these guarantees and indemnities have been 
immaterial. We estimate the fair value of our indemnification obligations as insignificant based on this history and insurance 
coverage and have, therefore, not recorded any liability for these guarantees and indemnities in the accompanying 
consolidated balance sheets.

We have federal and state tax net operating losses of $4.2 million and $15.0 million, respectively, as of December 31, 2024. 
The federal net operating losses acquired from the acquisition of Nobles Worldwide, Inc. are subject to an annual limitation 
under Internal Revenue Code Section 382; however, we expect to fully realize them under ASC Subtopic 740-10 before they 
begin to expire in 2038. The state net operating loss carryforwards include $2.3 million that is not expected to be realized due 
to various limitations and has been reduced by a valuation allowance. If not realized, the state net operating loss 
carryforwards, depending on the tax jurisdiction, will begin to expire between 2027 and 2038. 
We have state tax credit carryforwards of $12.5 million as of December 31, 2024, of which $2.4 million offsets uncertain tax 
positions, resulting in a deferred tax asset of $10.1 million ($8.0 million, net of Federal tax effect). A valuation allowance of 
$9.0 million ($7.1 million, net of Federal tax effect) has been provided on state tax credit carryforwards that are not expected 
to be realized under ASC Subtopic 740-10. Most of the state tax credit carryforwards do not expire. If not realized, the 
remaining state tax credit carryforwards, depending on the tax jurisdiction, will begin to expire between 2025 and 2039. 
We believe it is more likely than not that we will generate sufficient taxable income to realize the benefit of the remaining 
deferred tax assets.

Our total amount of unrecognized tax benefits was $4.5 million, $4.5 million, and $4.9 million at December 31, 2024, 2023, 
and 2022, respectively. We record interest and penalty charges, if any, related to uncertain tax positions as a component of 
tax expense and unrecognized tax benefits. The amounts accrued for interest and penalty charges as of December 31, 2024, 
2023, and 2022 were not significant. If recognized, $2.5 million would affect the effective income tax rate. As a result of 
statute of limitations set to expire in 2025, we expect decreases to our unrecognized tax benefits of $0.5 million in the next 
twelve months.
A reconciliation of the beginning and ending amount of unrecognized tax benefits was as follows:

We file U.S. Federal and state income tax returns. We are subject to examination by the Internal Revenue Service (“IRS”) for 
tax years after 2020 and by state taxing authorities for tax years after 2019. While we are no longer subject to examination 
prior to those periods, carryforwards generated prior to those periods may still be adjusted upon examination by the IRS or 
state taxing authorities if they either have been or will be used in a subsequent period. We believe we have adequately 
accrued for tax deficiencies or reductions in tax benefits, if any, that could result from the examination and all open audit 
years.
The Tax Cuts and Jobs Act of 2017 (“TCJA”), which was signed into U.S. law in December 2017, eliminated the option to 
immediately deduct research and development expenditures in the year incurred under Section 174 effective January 1, 2022. 
The amended provision under Section 174 requires us to capitalize and amortize these expenditures over five years (for U.S.-
based research). For the year ended December 31, 2024, we recorded an increase to income taxes payable of $8.1 million and 
an increase to net deferred tax assets of a similar amount. We are monitoring legislation for any further changes to Section 
174 and the potential impact to our financial statements in 2025.
In August 2022, the U.S. enacted the Inflation Reduction Act of 2022 (“IRA”) which aims to curb inflation by reducing the 
deficit, lowering prescription drug prices, and investing in domestic energy production while promoting clean energy. We 
considered the provisions in the IRA and determined they have no or minimal impact to our overall income taxes.

In August 2022, the U.S. enacted the Creating Helpful Incentives to Produce Semiconductors Act of 2022 (“CHIPS Act”) 
which provides new funding to boost domestic research and manufacturing of semiconductors in the United States. We 
considered the provisions in the CHIPS Act and determined they have no or minimal impact to our overall income taxes.
Note 16. Commitments and Contingencies
California’s Wage and Hour Laws Complaint
In December 2020, a representative action under California’s Private Attorneys General Act was filed against us in the 
Superior Court for the State of California, County of San Bernardino. We received service of process of this complaint in 
January 2021. The complaint alleged violations of California’s wage and hour laws relating to our current and former 
employees and sought attorney’s fees and penalties. We vigorously refuted and defended these claims, and reached a 
tentative settlement of $0.8 million during the fourth quarter 2021, which was subject to court approval. Thus, we recorded 
accrued liabilities of $0.8 million as of December 31, 2021. During the second quarter of 2022, additional factual information 
was identified resulting in an increase in the amount of the tentative settlement to $0.9 million. Therefore, we recorded an 
additional accrued liabilities of $0.1 million for a total accrued liabilities amount of $0.9 million as of the end of the second 
quarter of 2022, which amount remained unchanged as of December 31, 2022 as we were awaiting final court approval of 
this settlement. Subsequent to final court approval and payment of the $0.9 million in January 2023, during the third quarter 
of 2023 and upon plaintiff’s motion, the court re-opened the settlement agreement to determine whether the class list captured 
all affected employees. While we appealed that determination the appellate court upheld the trial court’s decision, and the 
case has been returned to the trial court for the parties to re-examine the class list. Any amount of additional liability is still 
undetermined pending the parties agreeing upon, and the court’s approval of, an updated class list, and as such, there is no 
amount of loss that is probable and reasonably estimable at this time. Thus, no additional accrual was recorded during the 
third quarter of 2023 or as of December 31, 2024.
Groundwater
Structural Systems has been directed by California environmental agencies to investigate and take corrective action for 
groundwater contamination at our facilities located in El Mirage and Monrovia, California. Based on currently available 
information, we have established an accrual for the estimated liability for such investigation and corrective action of $1.5 
million as of both December 31, 2024 and December 31, 2023, which is reflected in other long-term liabilities on our 
consolidated balance sheets.
Waste Disposal
Structural Systems also faces liability as a potentially responsible party for hazardous waste disposed at landfills located in 
Casmalia and West Covina, California. Structural Systems and other companies and government entities have entered into 
consent decrees with respect to these landfills with the United States Environmental Protection Agency and/or California 
environmental agencies under which certain investigation, remediation and maintenance activities are being performed. 
Based on currently available information, we preliminarily estimate that the range of our future liabilities in connection with 
the landfill located in West Covina, California is between $0.4 million and $3.1 million. We have established an accrual for 
the estimated liability in connection with the West Covina landfill of $0.4 million as of both December 31, 2024 and 
December 31, 2023, which is reflected in other long-term liabilities on our consolidated balance sheets. We anticipate an 
updated estimate will be available over the next 12 to 24 months however, and will update our accrual for the estimated 
liability at that time, if needed. Our ultimate liability in connection with these matters will depend upon a number of factors, 
including changes in existing laws and regulations, the design and cost of construction, operation and maintenance activities 
related to a final remedy, and the allocation of liability among potentially responsible parties.
Guaymas Performance Center Fire
In June 2020, a fire severely damaged our performance center in Guaymas, Mexico, which is part of our Structural Systems 
segment. There were no injuries; however, property and equipment, inventories, and tooling in this leased facility were 
damaged. Our Guaymas performance center, comprised of two buildings with an aggregate total of 62,000 square feet, was 
severely damaged. The loss of production from the Guaymas performance center was absorbed by our other existing 
performance centers; however, we have reestablished our operations and are in the process of certification with various 
customers and ramping up our manufacturing capabilities in a different leased facility with 117,000 square feet in Guaymas. 
A neighboring, non-related manufacturing facility also suffered fire damage during the same time as the fire that severely 
damaged our Guaymas performance center, and in November 2023, the occupant of the neighboring facility filed suit against 
us in U.S. District Court for the Central District of California seeking unspecified amounts for damages relating to the fire. In

addition, in July 2024, we received a subrogation demand from our landlord’s insurer, who also serves as one of our excess 
carriers, and requested the insurer to enter into an informed consent and conflict of waiver agreement to which we are 
awaiting a response. In the interim, discovery is ongoing, and we intend to defend these matters vigorously and believe we 
have substantial defenses in relation to these claims. As ultimate responsibility for the fire is still undetermined, there is no 
amount of loss that is probable and reasonably estimable at this time. If we are ultimately deemed to be responsible or partly 
responsible, it is possible we could incur a loss in excess of our insurance coverage limits, which could be material to our 
cash flow, liquidity, or financial results.
Our insurance covers damage, up to a capped amount, to the facility, equipment, unfinished inventory, and other assets at 
replacement cost, finished goods inventory at selling price, as well as business interruption, third party property damage, and 
recovery related expenses caused by the fire, less our per claim deductible. The anticipated insurance recoveries related to 
losses and incremental costs incurred are recognized when receipt is probable. The anticipated insurance recoveries in excess 
of net book value of the damaged operating assets and business interruption are not recorded until all contingencies related to 
our claim have been resolved.
The insurance claim for damages to our operating assets and business interruption was deemed final and closed by our 
insurance company during the three months ended July 1, 2023. Thus, the final $3.8 million of insurance recoveries were also 
received and recorded as other income during the three months ended July 1, 2023. In addition, the gain contingencies 
associated with the remaining general insurance recoveries that were received in 2020 of $3.9 million, but for which 
recognition was deferred until all the gain contingencies were resolved, were deemed resolved, and thus, recorded as other 
income during the three months ended July 1, 2023. Cumulatively, as of  July 1, 2023, we had received insurance recoveries 
in aggregate total of $23.7 million, with $7.5 million for business interruption and $16.2 million for damages to property and 
equipment, inventories, and tooling. Further, all insurance recovery amounts received related to this claim have been 
recognized up to the amount of net book value loss and presented within the same financial statement line item in the 
consolidated statements of income resulting in no net impact, with the remaining amounts recognized as other income in our 
consolidated statements of income when the contingencies were deemed resolved.
Other Structural Systems Performance Center Fire
In April 2023, a fire damaged a relatively small portion of one of our performance centers in our Structural Systems reporting 
segment. There were no injuries; however, subsequent to the fire, we determined that some property and equipment in this 
company-owned facility were damaged. Our insurance covers damage, up to a capped amount, to the property and equipment 
at replacement cost, as well as business interruption and recovery related expenses caused by the fire, less our per claim 
deductible. There was a loss of production in this damaged portion of the performance center for a short period of time, but 
the incident did not otherwise result in significant disruption to customer delivery schedules. Production in this damaged 
portion resumed later that same quarter. As such, during the three months ended July 1, 2023, we wrote off property and 
equipment with an aggregate total net book value of $0.2 million. Also during the three months ended July 1, 2023, we 
received insurance recoveries of $0.3 million (which was net of our deductible of $0.1 million) and thus, such insurance 
recoveries were also presented within the same financial statement line item in the consolidated statements of income 
resulting in no net impact. The amount of the insurance recoveries received in excess of the loss on operating assets was 
deemed a contingent gain, and since the gain contingencies were deemed resolved, the $0.1 million was also recorded as 
other income during the three months ended July 1, 2023. Finally, during the three months ended December 31, 2023, the 
insurance claim was deemed final and closed by our insurance company and we received a final payment of $0.3 million, 
which was recorded as other income.
In the normal course of business, Ducommun and its subsidiaries are defendants in certain other litigation, claims and 
inquiries, including matters relating to environmental laws. In addition, Ducommun makes various commitments and incurs 
contingent liabilities in the ordinary course of business. While it is not feasible to predict the outcome of these matters, 
Ducommun does not presently expect that any sum it may be required to pay in connection with these matters would have a 
material adverse effect on its consolidated financial position, results of operations or cash flows.
 
Note 17. Major Customers and Concentrations of Credit Risk
We provide proprietary products and services to the Department of Defense and various United States Government agencies, 
and most of the aerospace and aircraft manufacturers who receive contracts directly from the U.S. Government as an original

In 2024, 2023 and 2022, net revenues from foreign customers based on the location of the customer were $113.8 million, 
$82.2 million and $60.7 million, respectively. No net revenues from a foreign country were greater than three percent of total 
net revenues in 2024, 2023, and 2022. We have a manufacturing facility in Mexico. We also had a manufacturing facility in 
Thailand, however, we ceased manufacturing activities during 2023. Our net revenues, profitability and identifiable long-
lived assets attributable to foreign revenues activity were not material compared to our net revenues, profitability and 
identifiable long-lived assets attributable to our domestic operations during 2024, 2023, and 2022. We are not subject to any 
significant foreign currency risks as all our sales are made in United States dollars.
 
Note 18. Business Segment Information
We supply products and services primarily to the aerospace and defense industries. Our subsidiaries are organized into two 
strategic businesses, Electronic Systems and Structural Systems, each of which is an operating segment as well as a 
reportable segment. Electronic Systems designs, engineers and manufactures high-reliability electronic and electromechanical 
products used in worldwide technology-driven markets including A&D and Industrial end-use markets. Structural Systems 
designs, engineers and manufactures large, complex contoured aerostructure components and assemblies and supplies 
composite and metal bonded structures and assemblies. 
Our chief operating decision maker (“CODM”) is the Chairman, President and Chief Executive Officer. The measure used by 
the CODM to assess segment performance is segment operating income. Monitoring of segment operating income budgeted 
versus actual results is used for assessing performance of the segment and in establishing management’s compensation.
