ASTRONICS LETTER TO SHAREHOLDERS 
Dear Fellow Shareholders,  
2024 was an eventful year for Astronics, with many positive trends that 
benefited our business.  Our performance consistently improved as the year 
progressed, culminating in a strong fourth quarter which established solid 
momentum for 2025.  
During 2024 our supply chain became more predictable, our productivity 
improved, and employee turnover came down.  Inflation moderated after 
some years of accelerating cost pressure.  At the same time, market 
conditions remained strong and customer demand remained high.   
We had sales of $795.4 million, a 15% increase over the prior year.  Operating income was $26.5 million, much 
improved over the operating loss in 2023.  However, we had a net loss for the year of $16.2 million, or $(0.46) per 
share, due to a range of negative GAAP adjustments and the cost of two refinancings.  Looking past these 
issues, adjusted net income1 was $38.1 million, or $1.09 per share, up from $2.6 million, or $0.08 per share, in 
2023.   
We reported adjusted EBITDA1 of $96.5 million in 2024, a 74% improvement over the $55.6 million reported in 
2023.  Adjusted EBITDA margin1 expanded 400 basis points to 12.1% for the year and was 15.1% in the fourth 
quarter.  We also generated $30.6 million in cash in 2024, of which $26.4 million was generated in the fourth 
quarter.    
The improved margins and cash flow are positive indications that the business is healthy and returning to form 
after the disruption of the last few years.  
Strong Balance Sheet with Financial Flexibility Enables Investments in Growth 
We refinanced our debt first in July of 2024, taking advantage of an improved lending environment and our 
improved operating performance.  We did so again in November by issuing a $165 million convertible bond, 
under threat of a potentially negative legal ruling in a long running patent infringement case.  The eventual 
judgement, which came out in early 2025, was very much in our favor, initially requiring payment of only  
$12 million, though follow-on deliberations continue. 
The net result is that we are more comfortably capitalized today than at any other time in the last five years, with 
a balance sheet that supports our pursuit of the many opportunities in front of us.   
We plan capital expenditures in the range of $35 million to $40 million in 2025.  Capital investment has been 
constrained for the last several years and we have some catching up to do.  Additionally, we are working on 
certain capacity improvements that are necessary to accommodate the growth we expect over the next several 
years.   
Continued Strength in Aerospace Markets 
Aircraft production rates are increasing and aircraft utilization is high, driven by ever higher customer demand.  
This has also led to strong aftermarket activity, as airlines refresh their fleets with modern updates.  All of this is 
good for Astronics.   
1 Adjusted net income, adjusted EBITDA and adjusted EBITDA margin are non-GAAP financial metrics.  Please see the 
reconciliation of GAAP to non-GAAP financial measures following this letter.   

Our sales to the commercial transport market were up 21% in 2024.  Sales for the military aircraft market were 
up 43% year over year, while business jet sales were down marginally. 
Market forecasts call for these trends to continue in the near future , providing strong tailwinds for our business. 
 
 
 
 
 
 
 
 
 
Innovation Paves the Way for More Growth  
Technology innovation is at the heart of all we do at Astronics, and we are advancing on several programs that 
are the result of our responsiveness, creativity and engineering expertise.  We invested through the pandemic on 
a number of new programs that will contribute meaningfully to our success in the near future.   
Our Test business won a $215 million contract in 2024 to provide the test solution for the U.S. Army’s extensive 
range of radio communication devices.  The program contributed approximately $9 million in revenue in 2024 for 
engineering development, qualification, and low rate initial production.  We expect to begin volume production 
later in 2025.   
We have also made good progress on our contract for the U.S. Army Future Long Range Assault Aircraft (“FLRAA”), 
otherwise known as the Bell V-280.  This promises to be a significant program for Astronics.  While the 
development stage is expected to generate approximately $60 million to $65 million over the next couple of 
years, we expect we will have over $1 million in shipset content once in production, among the highest in our 
history.  Prototypes are expected to fly in 2026 and low rate initial production is expected to begin in 2028 with 
production rates increasing over time.  The V-280 is expected to replace the UH-60 Blackhawk helicopter.  The 
U.S. Army has over 2,000 in its fleet and over 5,000 have been built since its introduction in 1979. 
We announced back in 2022 that Southwest had selected our newly designed EMPOWER® UltraLite G2 Power 
System.  This system provides 60W USB Type-C and 10.5W Type A USB charging ports at every passenger seat.  
Like Southwest, narrow-body operators around the world have enthusiastically embraced the system.  Including 
Southwest’s plans, there are now over 1,500 narrow-body aircraft committed to installations and hundreds 
already in operation with the UltraLite G2.  Our system boasts a 30% to 40% reduction in weight compared with 
previous generation systems, supporting airlines' efforts to reduce carbon emissions. 
These programs, and others like them, point to a promising future for Astronics, and we will continue to innovate 
and capture more content on winning aircraft platforms to drive organic growth.

BACKLOG 

Looking Forward 
We expect 2025 will be a very good year for Astronics.  We entered the year with a record beginning backlog of 
$599.2 million.  This book of business, combined with the many positive macro-economic tailwinds we are 
experiencing, gives us a lot of confidence as we start out the year.   
Our initial revenue expectation is $820 million to $860 million which, at the midpoint, would be a 6% increase 
over 2024 sales.  We have seen average sales growth of 22% over the last three years, and we believe that the 
more reasonable growth rate expected for 2025 will allow us to optimize margins and financial performance in 
ways we could not do so recently.  We also expect that pricing initiatives we have implemented will be a positive 
factor as the year progresses.  We expect that our profitability will grow at a faster rate than sales. 
We believe we are set for a very rewarding 2025. 
Thank you for your support and investment in Astronics.   
Sincerely,  
 
 
 
 
Peter J. Gundermann 
Chairman, President and CEO

This annual report wrap and letter includes forward-looking statements as described in the section of the 
enclosed Annual Report on Form 10-K entitled “Forward-Looking Statements.” 
Use of Non-GAAP Financial Metrics and Additional Financial Information 
In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, 
Astronics provides Adjusted Non-GAAP information as additional information for its operating results.  
References to Adjusted Non-GAAP information are to non-GAAP financial measures.  These measures are not 
required by, in accordance with, or an alternative for, GAAP and may be different from non-GAAP financial 
measures used by other companies.  Astronics management uses these measures for reviewing the financial 
results of Astronics for budget planning purposes and for making operational and financial decisions.  
Management believes that providing these non-GAAP financial measures to investors, as a supplement to GAAP 
financial measures, help investors evaluate Astronics core operating and financial performance and business 
trends consistent with how management evaluates such performance and trends.

Adjusted Net Income and Adjusted Diluted EPS are defined as net income and diluted EPS as reported, adjusted 
for certain items, including amortization of intangibles, and also adjusted for a normalized tax rate.  Adjusted 
Net Income and Adjusted Diluted EPS are not measures determined in accordance with GAAP and may not be 
comparable with the measures used by other companies. Nevertheless, the Company believes that providing 
non-GAAP financial measures, such as Adjusted Net Income and Adjusted Diluted EPS, are important for 
investors and other readers of the Company’s financial statements and assists in understanding the 
comparison of the current quarter’s and current year’s net income and diluted EPS to the historical periods’ net 
income and diluted EPS, as well as facilitates a more meaningful comparison of the Company’s net income and 
diluted EPS to that of other companies.  The Company believes that presenting Adjusted Diluted EPS provides a 
better understanding of its earnings power inclusive of adjusting for the non-cash amortization of intangible 
assets, reflecting the Company’s strategy to grow through acquisitions as well as organically.

Adjusted EBITDA is defined as net income before interest expense, income taxes, depreciation, amortization, 
and other adjustments.  Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by sales.  Adjusted 
EBITDA and Adjusted EBITDA Margin are not measures determined in accordance with GAAP and may not be 
comparable with Adjusted EBITDA and Adjusted EBITDA Margin as used by other companies.  Nevertheless, the 
Company believes that providing non-GAAP financial measures, such as Adjusted EBITDA and Adjusted EBITDA 
Margin, are important for investors and other readers of the Company’s financial statements.

PART I
ITEM 1. 
BUSINESS
Astronics Corporation (“Astronics” or the “Company”) is a leading provider of advanced technologies to the global aerospace, 
defense and electronics industries. Our products and services include advanced, high-performance electrical power generation, 
distribution and motion systems, lighting and safety systems, avionics products, systems and certification, aircraft structures 
and automated test systems.
We have principal operations in the United States (“U.S.”), Canada and France, as well as engineering offices in Ukraine and 
India. Our operation in Ukraine is a small engineering office and we have not experienced any significant disruption in staffing 
or services as a result of the Ukrainian and Russian conflict. 
Refinancing
On July 11, 2024, the Company completed a financing transaction that refinanced its previous credit facilities. The refinancing 
consisted of an amendment and restatement of the Company’s asset-based revolving credit facility with a principal amount 
available to be borrowed thereunder of $200.0 million (the “ABL Revolving Credit Facility”), with amounts borrowed 
thereunder carrying an interest rate of SOFR plus between 2.50% to 3.00%. The Company also entered into a $55.0 million 
term loan facility (the “Term Loan Facility”) at an interest rate of SOFR plus a term SOFR plus between 5.50% to 6.75%.
On November 25, 2024, the Company amended the ABL Revolving Credit Facility increasing the revolving credit line to 
$220.0 million with an interest rate of SOFR plus 2.75% to 3.25% (an increase of 0.25% to each such applicable margin). 
On December 3, 2024, the Company issued $165.0 million aggregate principal amount of 5.500% Convertible Senior Notes 
(the “Convertible Notes”), which amount includes the additional notes issued pursuant to the initial purchasers’ full exercise of 
their option to purchase additional Convertible Notes. The Convertible Notes will mature on March 15, 2030, unless earlier 
converted, redeemed or repurchased. On December 3, 2024, the Company repaid in full all outstanding indebtedness on the 
Term Loan Facility. For additional information, see discussion in Item 7, Management’s Discussion and Analysis of Financial 
Condition and Results of Operations, and Note 8, Long-Term Debt, to the Consolidated Financial Statements in Item 8, 
Financial Statements and Supplementary Data, of this report.
Divestitures
On February 13, 2019, the Company completed a divestiture of its semiconductor test business within the Test Systems 
segment. The total proceeds of the divestiture included two elements of contingent purchase consideration (“earnout”). In 
March 2022, the Company agreed with the earnout calculation for the calendar 2021 earnout in the amount of $11.3 million. 
The Company recorded the gain and received the payment in the first quarter of 2022. In March 2023, the Company agreed 
with the final earnout calculation for the calendar 2022 earnout in the amount of $3.4 million. The Company recorded the gain 
and received the payment in the first quarter of 2023. We are not eligible for any further earnout payments related to this 
divestiture. For further information, see Note 21, Divestiture Activities, to the Consolidated Financial Statements in Item 8, 
Financial Statements and Supplementary Data, of this report.
Customer Bankruptcies
In October 2024, a customer reported within the Aerospace segment declared bankruptcy. As a result, the Company recorded a 
full reserve of $1.0 million for outstanding receivables, a reserve of $1.7 million for inventory and $0.6 million for impairment 
of fixed assets.
In November 2023, a non-core contract manufacturing customer reported within the Aerospace segment filed for bankruptcy 
under Chapter 11. As a result, the Company recorded a full reserve of $7.5 million for outstanding accounts receivable and a 
reserve of $3.6 million for inventory. 
Products and Customers
Our Aerospace segment designs and manufactures products for the global aerospace industry. Product lines include lighting and 
safety systems, electrical power generation, distribution and seat motion systems, aircraft structures, avionics products, systems 
certification, and other products. Our Aerospace customers are the airframe manufacturers (“OEM”) that build aircraft for the 
commercial transport, military and general aviation markets, suppliers to those OEMs, aircraft operators such as airlines, 
suppliers to the aircraft operators, and branches of the U.S. Department of Defense. During 2024, this segment’s sales were 
divided 74% to the commercial transport market, 12% to the military aircraft market, 11% to the general aviation market and 
3% to other markets. Most of this segment’s sales are a result of contracts or purchase orders received from customers, placed 
6

on a day-to-day basis or for a single year procurement rather than long-term multi-year contract commitments. On occasion, the 
Company does receive contractual commitments or blanket purchase orders from our customers covering multiple-year 
deliveries of hardware to our customers.
Our Test Systems segment designs, develops, manufactures and maintains automated test systems that support the aerospace 
and defense, communications and mass transit industries as well as training and simulation devices for both commercial and 
military applications. In the Test Systems segment, Astronics’ products are sold to a global customer base including OEMs and 
prime government contractors for both electronics and military products. The nature of our Test Systems business is such that it 
pursues large, often multi-year, projects.
Sales by segment, geographic region, major customer and foreign operations are provided in Note 20, Segments, to the 
Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data, of this report.
We have a significant concentration of business with one major customer, The Boeing Company (“Boeing”). Sales to Boeing 
accounted for 10.2% of sales in 2024, 11.0% of sales in 2023, and 11.0% of sales in 2022. Sales to Boeing are primarily in the 
Aerospace segment.
Strategy
Our strategy is to increase our value by developing technologies and capabilities either internally or through acquisition, and 
use those capabilities to provide innovative solutions to our targeted markets where our technology can be beneficial.
Practices as to Maintaining Working Capital
Liquidity is discussed under the heading “Liquidity and Capital Resources”, in Item 7, Management’s Discussion and Analysis 
of Financial Condition and Results of Operations, of this report.
Competitive Conditions
We experience considerable competition in the market sectors we serve, principally with respect to product performance and 
price, from various competitors, many of which are substantially larger and have greater resources than we do. Success in the 
markets we serve depends upon product innovation, customer support, responsiveness and cost management. We continue to 
invest in developing the technologies and engineering support critical to competing in our markets.
Government Contracts
All U.S. government contracts, including subcontracts where the U.S. government is the ultimate customer, may be subject to 
termination at the election of the government. Our revenue stream relies on military spending. Approximately 15% of our 2024 
consolidated sales were made to U.S. government-related markets.
Government Regulation
The FAA regulates the manufacture, repair and operation of all aircraft and aircraft parts operated in the United States. Its 
regulations are designed to ensure that all aircraft and aviation equipment are continuously maintained in proper condition to 
ensure safe operation of the aircraft. Similar rules apply in other countries. All aircraft must be maintained under a continuous 
condition monitoring program and must periodically undergo thorough inspection and maintenance. The inspection, 
maintenance and repair procedures for the various types of aircraft and equipment are prescribed by regulatory authorities and 
can be performed only by certified repair facilities utilizing certified technicians. Certification and conformance is required 
prior to installation of a part on an aircraft. Our operations may in the future be subject to new and more stringent regulatory 
requirements. In that regard, we closely monitor the FAA and industry trade groups in an attempt to understand how possible 
future regulations might impact us. Our businesses which sell products directly to the U.S. Government or for use in systems 
delivered to the U.S. Government can be subject to various laws and regulations governing pricing and other factors.
There has been no material adverse effect to our Consolidated Financial Statements nor competitive positions as a result of 
these government regulations.
Raw Materials
Materials, supplies and components are purchased from numerous sources. We believe that the loss of any one source, although 
potentially disruptive in the short-term, would not materially affect our operations in the long-term.
7

Seasonality
Our business is typically not seasonal.
Backlog
At December 31, 2024, our consolidated backlog was $599.2 million. At December 31, 2023, our backlog was $586.6 million. 
The increase in backlog is driven primarily by recovering demand from our commercial transport and general aviation 
customers, with increased OEM build rates and increased spending by commercial airlines on fleet improvements. The backlog 
in each of the periods presented excludes backlog associated with the customer bankruptcies referred to previously.
Backlog in the Aerospace segment was $537.6 million at December 31, 2024. Backlog in the Test Systems segment was 
$61.7 million at December 31, 2024.
Patents
We have a number of patents. While the aggregate protection of these patents is of value, our only material business that is 
dependent upon the protection afforded by these patents is our cabin power distribution products. Our patents and patent 
applications relate to electroluminescence, instrument panels, cord reels and handsets, and a broad patent covering the cabin 
power distribution technology. We regard our expertise and techniques as proprietary and rely upon trade secret laws and 
contractual arrangements to protect our rights. We have trademark protection in our major markets.
Research and Development Expenses
Research and development costs are expensed as incurred and include salaries, benefits, consulting, material costs and 
depreciation. Research and development expenses amounted to $52.1 million in 2024, $53.5 million in 2023 and $48.3 million 
in 2022. These costs are included in Cost of Products Sold.
Government Subsidies
In September 2021, the Company was awarded a grant of up to $14.7 million from the U.S. Department of Transportation 
(“USDOT”) under the Aviation Manufacturing Jobs Protection Program (“AMJP”). The Company received $7.3 million under 
the grant in 2022. The grant benefit was recognized ratably over the six-month performance period as a reduction to Cost of 
Products Sold in proportion to the compensation expense that the award was intended to defray. During the year ended 
December 31, 2022, the Company recognized $6.0 million of the award.
Human Capital Resources
Human Capital Management and Corporate Culture
As of December 31, 2024, we employed approximately 2,500 full-time employees, of whom approximately 2,000 were 
employed in the United States and approximately 500 were employed outside of the United States. We have approximately 120 
non-exempt production employees at PECO who are subject to collective bargaining agreements. We also leverage temporary 
workers to provide flexibility for our business and manufacturing needs.
We greatly value our employees and recognize that, without them, the Company would not have achieved the success it has 
accomplished since inception. We strive to provide a positive, supportive work culture with a clear global vision and a 
collaborative work style. We strongly believe that a focus on learning and supporting career development can lead to success. 
Astronics Corporation regularly earns “best employer” awards. 
As it relates to customers, investors, suppliers and partners, our Company is dedicated to conducting business with integrity and 
responsibility for the greater good. We promote honest and ethical conduct, compliance with applicable government regulations 
and accountability by all of its directors, officers and employees.
When considering an acquisition or partnership, we embed questions specific to human capital management within our due 
diligence approach. These questions are in the areas of culture, equal employment opportunity, compliance with governing 
bodies, ethics, as well as employee benefits. We ask these in an effort to ensure that the acquisition candidate is a positive 
cultural fit and to minimize any risk when assessing the acquisition candidate.
In addition, our Corporate Governance Guidelines outline expectations that the Board establish and promote policies that 
encourage a positive, supportive work culture. The Board recognizes that culture is critical to the long-term success of 
Astronics and our strategy.
8

Compensation Programs and Employee Benefits
We believe that future success largely depends upon our continued ability to attract and retain highly skilled employees. We 
provide employees with competitive salaries and bonuses, opportunities for equity ownership, development programs that 
enable continued learning and growth and a robust employment package that promotes well-being across all aspects of their 
lives, including;
•
Health and dental insurance
•
Generous paid time off
•
401K, profit sharing, and bonus programs
•
Flexible spending accounts
•
Employee stock purchase plan
•
Disability and life insurance
•
Commute reduction, fitness, and tuition programs
•
Community service opportunities
Employee Engagement 
The lifeblood of any organization is its employee base. We rely on our individual subsidiaries to regularly gather employee 
feedback, using the method each subsidiary believes is most appropriate. In some instances that feedback is obtained through 
“Town Hall” formats; in other instances, it is obtained through surveys. We also expect our managers to solicit and, where 
applicable, use employee feedback to improve its business practices and working environment. We are proud to have received 
numerous awards, recognizing both product quality as well as the ability to provide an excellent work environment.
Inclusion 
The Company believes that inclusion is important to attract and retain top talent. Astronics has an Equal Employment 
Opportunity Policy whereby the Company commits to providing equal employment opportunity and affirmative action plans for 
all qualified employees and applicants without regard to race, color, sex, sexual orientation, gender identity, religion, national 
origin, disability, veteran status, age, marital status, pregnancy, genetic information or other legally protected status. 
Health and Safety
Astronics is committed to the safety of our customers and our employees. Each Astronics operation maintains environmental, 
health and safety policies and practices that seek to promote the operation of its businesses in a manner that is protective of the 
health and safety of the public and its employees.
Our operations offer several health and welfare programs to employees to promote fitness and wellness and to encourage 
preventative healthcare. In addition, our employees are offered a confidential employee assistance program that provides 
professional counseling to employees and their family members. Also, many of our operations offer green space for employees 
to use during their breaks.

ITEM 1A.
RISK FACTORS
Our business faces many risks, and you should carefully consider the following risk factors, together with all of the other 
information included in this report, including the financial statements and related notes contained in Item 8, Financial 
Statements and Supplementary Data, and discussion in Item 7, Management’s Discussion and Analysis of Financial Condition 
and Results of Operations, when deciding to invest in us. Any of the risks discussed below, or elsewhere in this report or in our 
other SEC filings, could have a material impact on our business, financial condition or results of operations. Additional risks 
not currently known to us or that we currently consider immaterial also may materially adversely affect our business, financial 
condition or results of operations in the future. As a result, the trading price of our common stock could decline, and you could 
lose all or part of your investment in our common stock.
Market Risks
The loss of Boeing as a major customer or a significant reduction in business with this customer would reduce our sales 
and earnings. In 2024, 2023, and 2022 we had a concentration of sales to Boeing representing approximately 10.2%, 11.0%, 
and 11.0% of our sales, respectively. Revenue earned from sales to Boeing may decline or fluctuate significantly in the future. 
We may not be able to offset any decline in sales from Boeing with sales from new customers or other existing customers. The 
loss of Boeing as a customer or a significant reduction in business with Boeing would significantly reduce our sales and 
earnings. Accordingly, a portion of our potential for success will depend on our continued ability to develop and manage our 
relationship with Boeing.
The markets we serve are cyclical and sensitive to domestic and foreign economic conditions, conflicts and events, which 
may cause our operating results to fluctuate. The markets we serve are sensitive to fluctuations in general business cycles, 
global pandemics, domestic and foreign governmental tariffs, trade and monetary policies, national and international conflicts, 
and economic conditions and events. While both domestic air travel and international air travel utilizing primarily widebody 
aircraft have recovered from the impact of the COVID-19 pandemic, if a global health crisis similar to the COVID-19 pandemic 
were to occur in the future, we may find it difficult to access our existing financing or obtain additional financing and/or fund 
our operations and meet our debt service obligations. Any new pandemic or other future public health crisis could materially 
adversely affect our business, financial condition and results of operations.
In our Aerospace segment, demand by the general aviation markets for our products is dependent upon several factors, 
including capital investment, product innovations, economic growth and wealth creation and technology upgrades. In addition, 
the commercial airline industry is highly cyclical, with significant downturns in the past and sensitivity to such things as fuel 
price increases, labor disputes, global economic conditions, availability of capital to fund new aircraft purchase and upgrades of 
existing aircraft and passenger demand. Any change in these factors could result in a further reduction in the amount of 
10

discretionary air travel and the ability of airlines to invest in new aircraft or to upgrade existing aircraft. Therefore, our business 
is directly affected by economic factors outside of our control and other trends that affect our customers in the commercial 
aerospace industry. These factors could reduce orders for new aircraft and could reduce airline investment in cabin upgrades for 
which we supply products, thus reducing our sales and profits. A reduction in air travel may also result in our commercial 
airline customers being unable to pay our invoices on a timely basis or at all. 
We are a supplier on various new aircraft programs just entering or expected to begin production in the future. As with any new 
program, there is risk as to whether the aircraft or program will be successful and accepted by the market. As is customary for 
our industry, we purchase inventory and invest in specific capital equipment to support our production requirements generally 
based on delivery schedules provided by our customer. If a program or aircraft is not successful, we may have to write-off all or 
a part of the inventory, accounts receivable and capital equipment related to the program. A write-off of these assets could 
result in a significant reduction of earnings and cause covenant violations relating to our debt agreements. This could result in 
our being unable to borrow additional funds under the ABL Revolving Credit Facility or being obliged to refinance or 
renegotiate our indebtedness on potentially unfavorable terms for us.
In our Test Systems segment, the market for our products is concentrated with a limited number of significant customers 
accounting for a substantial portion of the purchases of test equipment. In any one reporting period, a single customer or several 
customers may contribute to an even larger percentage of our consolidated sales. In addition, our ability to increase sales will 
depend, in part, on our ability to obtain orders from current or new significant customers. The opportunities to obtain orders 
from these customers may be limited, which may impair our ability to grow sales. We expect that sales of our Test Systems 
products will continue to be concentrated with a limited number of significant customers for the foreseeable future. 
Additionally, demand for some of our test products is dependent upon certain factors, including government funding levels for 
our products, our ability to compete successfully for those contracts and our ability to develop products to satisfy the demands 
of our customers. A negative change in any of these factors could materially adversely affect our business, financial condition, 
results of operations, and cash flows.
Our products are sold in highly competitive markets. Some of our competitors are larger, more diversified corporations and 
have greater financial, marketing, production and research and development resources than we do. As a result, certain of our 
competitors may be better able to withstand the effects of periodic economic downturns or other market changing events. Our 
operations and financial performance will be negatively impacted if our competitors:
•
develop products that are superior to our products;
•
develop products that are more competitively priced than our products;
•
develop methods of more efficiently and effectively providing products and services; or
•
adapt more quickly than we do to new technologies, such as generative artificial intelligence (“AI”), or evolving 
customer requirements.
We believe that the principal points of competition in our markets are product quality, price, design and engineering 
capabilities, product development, conformity to customer specifications, quality of support after the sale, timeliness of delivery 
and effectiveness of the distribution organization. Maintaining and improving our competitive position will require continued 
investment in manufacturing, engineering, quality standards, marketing, customer service and support and our distribution 
networks. If we do not maintain, or are otherwise unable to maintain, sufficient resources to make these investments, or are not 
successful in maintaining our competitive position, our business operations and financial performance may be materially 
adversely affected.
We depend on government contracts and subcontracts with defense prime contractors and subcontractors that may not 
be fully funded, may be terminated, or may be awarded to our competitors. The failure to be awarded these contracts, 
the failure to receive funding or the termination of one or more of these contracts could reduce our sales. Sales to the 
U.S. government and its prime contractors and subcontractors represent a significant portion of our business. The funding of 
these programs is generally subject to annual congressional appropriations, and presidential and congressional priorities are 
unpredictable and subject to change. We cannot be certain that current levels of congressional funding for programs involving 
our products or services will continue and that our business related to these products and services will not decline or increase at 
currently anticipated levels, or that we will not be subject to delays in the negotiation of contracts or increased costs due to 
changes in the funding of U.S. government programs or government shutdowns. In addition, government expenditures for 
defense programs may decline or these defense programs may be terminated. A decline in governmental expenditures, a change 
in spending priorities, or the U.S. government’s termination of existing contracts may result in a reduction in the volume of 
government contracts awarded to us. Furthermore, on government contracts for which we are a subcontractor and not the prime 
contractor, the U.S. government could terminate the prime contract for convenience or otherwise, irrespective of our 
performance as a subcontractor. Also, sales to the U.S. government and its contractors, as well as foreign military and 
government customers, either directly or as a subcontractor to other contractors, often use a competitive bidding process and 
11

have unique purchasing and delivery requirements, which often makes the timing of sales to these customers unpredictable. We 
have resources applied to specific government contracts, and if any of those contracts were terminated, we may incur 
substantial costs redeploying those resources and our business, financial condition, results of operations, and cash flows may be 
materially adversely affected.
Contracting in the defense industry is subject to significant regulation, including rules related to bidding, billing and 
accounting kickbacks and false claims, and any non-compliance could subject us to fines and penalties or possible 
debarment. Like all government contractors, we are subject to risks associated with this contracting. These risks include the 
potential for substantial civil and criminal fines and penalties. These fines and penalties could be imposed for failing to follow 
procurement integrity and bidding rules, employing improper billing practices or otherwise failing to follow cost accounting 
standards, receiving or paying kickbacks or filing false claims. We have been, and expect to continue to be, subjected to audits 
and investigations by government agencies. The failure to comply with the terms of our government contracts could harm our 
business reputation, which could materially reduce our sales and earnings. It could also result in our suspension or debarment 
from future government contracts, which could materially adversely affect our business, financial condition, results of 
operations, and cash flows.
Strategic Risks
If we are unable to adapt to technological change, demand for our products may be reduced. The technologies related to 
our products have undergone, and in the future may undergo, significant changes. To succeed in the future, we will need to 
continue to design, develop, manufacture, assemble, test, market and support new products and enhancements on a timely and 
cost-effective basis, and we cannot be certain that we will be able to do so successfully, if at all, or on a timely, cost effective, 
or repeatable basis. Our competitors may develop technologies and products that are more effective than those we develop or 
that render our technology and products obsolete or noncompetitive. Furthermore, our products could become unmarketable if 
new industry standards emerge. We may have to modify our products significantly in the future to remain competitive, and new 
products we introduce may not be accepted by our customers.
Our new product development efforts may not be successful, which could result in a reduction in our sales and earnings. 
We may experience difficulties that could delay or prevent the successful development of new products or product 
enhancements, and new products or product enhancements may not be accepted by our customers. Because it is difficult to 
predict the amount of time required and the costs involved in achieving certain research, development, and engineering 
objectives, the development expenses we incur may exceed our cost estimates and estimated product development schedules 
may be extended. Furthermore, any new products we develop may not generate sales sufficient to offset our costs. If any of 
these events occur, our sales and profits could be materially adversely affected.
We may incur losses and liabilities as a result of our acquisition strategy. Part of our business strategy involves developing 
technologies and capabilities through acquisitions. Growth by acquisition involves risks that could materially adversely affect 
our business, financial condition and results of operations, including:
•
the potential exposure to unanticipated liabilities;
•
the potential that expected benefits or synergies are not realized and that operating costs increase;
•
the risks associated with incurring additional acquisition indebtedness, including that additional indebtedness could 
limit our cash flow availability for operations and our flexibility;
•
difficulties in integrating the operations and personnel of acquired companies;
•
the potential loss of key employees, suppliers or customers of acquired businesses; and
•
diversion of management time and attention from our core business.
In addition, any acquisition, once successfully integrated, could negatively impact our financial performance if it does not 
perform as planned, does not increase earnings, or does not prove otherwise to be beneficial to us. We cannot provide any 
assurances that we will be able to complete any acquisitions and then successfully integrate the business and operations of those 
acquisitions without encountering the risks described above. If we are not able to efficiently integrate an acquisition’s business 
and operations into our organization in a timely and efficient manner, or at all, the anticipated benefits of the acquisition may 
not be realized, or it may take longer to realize these benefits than we currently expect, either of which could materially 
adversely affect our business, financial condition and results of operations.
12

Operational Risks
Our business and operations could be adversely impacted in the event of a failure of our information technology 
infrastructure or adversely impacted by a successful cyber-attack. We are dependent on various information technologies 
throughout our Company to administer, store and support multiple business activities. We routinely experience various 
cybersecurity threats, threats to our information technology infrastructure, unauthorized attempts to gain access to our sensitive 
information, and denial-of-service attacks, and our customers, suppliers and subcontractors face similar cybersecurity threats. 
We conduct regular periodic training of our employees as to the protection of sensitive information, which includes security 
awareness training intended to prevent the success of “phishing” attacks. 
The threats we face vary from attacks common to most industries, such as ransomware attacks to disable critical infrastructure 
and extort companies for ransom payments, to more advanced and persistent, highly organized adversaries, including nation 
states, which target us and other defense contractors because we protect sensitive information. If we are unable to protect 
sensitive information, our customers or governmental authorities could question the adequacy of our threat mitigation and 
detection processes and procedures, and depending on the severity of the incident, our customers’ data, our employees’ data, 
our intellectual property, and other third-party data (such as subcontractors, suppliers and vendors) could be compromised. As a 
consequence of the persistence, sophistication and volume of these bad actors, we may not be successful in defending against 
all such attacks. Due to the evolving nature of these security threats, the impact of any future cybersecurity incident cannot be 
predicted with reasonable certainty.
Although we work cooperatively with our customers, suppliers, and subcontractors to seek to minimize the impact of 
cybersecurity threats, other security threats or business disruptions, we must rely on the safeguards put in place by these 
entities, which may affect the security of our information. These entities have varying levels of cybersecurity expertise and 
safeguards and their relationships with U.S. government contractors, such as Astronics, may increase the likelihood that they 
are targeted by the same cybersecurity threats we face. Furthermore, our customers, suppliers and subcontractors may 
incorporate AI tools without disclosing this use to us, and the providers of these AI tools may not meet existing or rapidly 
evolving regulatory or industry standards with respect to privacy and data protection and may inhibit our or their ability to 
maintain an adequate level of service and experience. If we or our customers, suppliers or subcontractors experience an actual 
or perceived breach or privacy or security incident because of the use of AI, we may lose valuable confidential information and 
our reputation and the public perception of the effectiveness of our security measures could be harmed.
If we experience a data security breach from an external source or from an insider threat, we may have a loss in sales or 
increased costs arising from the restoration or implementation of additional security measures, either of which could adversely 
affect our business and financial results. Other potential costs could include damage to our reputation, loss of brand value, 
incident response costs, decrease in the price of our common stock, regulatory inquiries, litigation and management distraction 
from operating our business. A security breach that involves classified information could subject us to civil or criminal 
penalties, loss of a government contract, loss of access to classified information, or debarment as a government contractor. 
Similarly, a breach that involves loss of customer-provided data could subject us to loss of a customer, loss of a contract, 
litigation costs and legal damages and reputational harm. One or more of these results could materially adversely affect our 
business, financial condition and results of operations. 
Our inability to adequately enforce and protect our intellectual property or defend against assertions of infringement 
could prevent or restrict our ability to compete. We rely on patents, trademarks and proprietary knowledge and technology, 
both internally developed and acquired, in order to maintain a competitive advantage. Our inability to defend against the 
unauthorized use of these intellectual property rights and assets could have an adverse effect on our results of operations and 
financial condition. We cannot assure you that our means of protecting our intellectual property rights in the United States or 
abroad will be adequate, or that others will not develop technologies similar or superior to our technology or design around our 
proprietary rights. Litigation may be necessary to protect our intellectual property rights or defend against claims of 
infringement. This litigation could result in significant costs and divert our management’s focus away from our core business 
operations. Refer to the risk factor below under the heading “Currently, our subsidiary, Astronics Advanced Electronic Systems 
Corp., is a defendant in actions filed in various jurisdictions by Lufthansa Technik AG relating to an allegation of patent 
infringement and based on rulings to date, we have concluded that losses related to these proceedings are probable” and 
Note 19, Legal Proceedings, to the Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data, 
of this report for further discussion.

If critical components or raw materials used to manufacture our products or used in our development programs become 
scarce or unavailable, then we may incur delays in manufacturing and delivery of our products and in completing our 
development programs, which has damaged, and could continue to damage, our business, results of operations and 
financial condition. Due to increased demand across a range of industries, the global supply chain for certain critical 
components and raw materials used in the manufacture of our products and used in our development programs has in the past 
experienced, and may in future periods experience, significant strain. A constrained supply environment has in the past 
adversely affected, and could in the future adversely affect, availability, lead times and the cost of components, and could 
impact our ability to timely complete development programs, respond to accelerated or quick-turn delivery requests from 
customers, or meet customer demand and product delivery dates for our end customers in situations where we cannot timely 
secure adequate supply of these components. Moreover, if any of our suppliers become financially unstable, or otherwise 
unable or unwilling to provide us with raw materials or components, then we may have to find new suppliers. It may take 
several months to locate alternative suppliers, if required, or to redesign our products to accommodate components from 
different suppliers. We may experience significant delays in manufacturing and shipping our products to customers and incur 
additional development, manufacturing and other costs to establish alternative sources of supply if we lose any of these sources 
or are required to redesign our products. We cannot predict if we will be able to obtain replacement components within the time 
frames that we require at an acceptable cost, if at all. 
In an effort to mitigate these risks, in some cases, we have incurred higher costs to secure available inventory or have extended 
or placed non-cancellable purchase commitments with suppliers, which introduces inventory risk if our forecasts and 
assumptions prove inaccurate. While we may attempt to recover the increased costs through price increases to our customers, 
we may be unable to mitigate the effect on our results of operations. We have also multi-sourced and pre-ordered components 
and raw materials inventory in some cases in an effort to reduce the impact of the adverse supply chain conditions we have 
experienced or may experience in the future. Limits on manufacturing availability or capacity or delays in production or 
delivery of components or raw materials could delay or inhibit our ability to obtain supply of components and produce finished 
goods. Supply chain constraints and their related challenges could result in shortages, increased material costs or use of cash, 
engineering design changes, and delays in new product introductions, each of which could materially adversely affect our 
growth, gross margin and financial results. These types of negative financial impacts on our business may become more acute if 
supply chain pressures increase.
Our financial results could continue to be adversely impacted by the escalation of labor and benefit costs. Consistent with 
the experience of other employers, our labor, medical and workers’ compensation costs have increased substantially in recent 
years and are expected to continue to rise. If this trend continues, the cost of labor and to provide healthcare and other benefits 
to our employees could continue to increase, which could materially adversely affect our future profitability. Competition for 
employees has escalated in the labor market which has increased costs associated with attracting and retaining skilled 
employees. We cannot be certain that we will be able to maintain an adequately skilled labor force necessary to operate 
efficiently or that our labor costs will not increase as a result of a shortage in the availability of skilled employees. Any 
significant increases in the costs attributable to our self-insured health and workers’ compensation plans could adversely impact 
our business, results of operations, financial condition and cash flows.
Price inflation for labor and materials, further exacerbated by the Russian invasion of Ukraine or the Israel-Hamas 
war, could adversely affect our business, results of operations and financial condition. We have experienced considerable 
price inflation in our costs for labor and materials in recent years, which has materially adversely affected our business, results 
of operations and financial condition. We may not be able to pass through to our customers inflationary cost increases under our 
existing fixed-price contracts. Our ability to raise prices to reflect increased costs may be limited by competitive conditions in 
the market for our products and services. Russia’s invasion of Ukraine and the Israel-Hamas war, and prolonged conflict in 
either such situation, may continue to result in increased inflation, escalating energy and commodity prices and increasing costs 
of materials. We continue to work to mitigate such pressures on our business operations as they develop. To the extent the war 
in Ukraine or the Israel-Hamas war adversely affects our business as discussed above, it may also have the effect of heightening 
many of the other risks described herein, such as those relating to cybersecurity, supply chain, volatility in prices and market 
conditions, any of which could negatively affect our business and financial condition.
If our subcontractors fail to perform their contractual obligations, our prime contract performance and our ability to 
obtain future business could be materially adversely affected. Many of our contracts involve subcontracts with other 
companies upon whom we rely to perform a portion of the services we must provide to our customers. There is a risk that we 
may have disputes with our subcontractors, including disputes regarding the quality and timeliness of work performed by the 
subcontractor or customer concerns about the subcontractor. Failure by our subcontractors to satisfactorily provide, on a timely 
basis, the agreed-upon supplies or perform the agreed-upon services may materially adversely affect our ability to perform our 
obligations to our customer and could result in the assessment of late delivery penalties. Subcontractor performance deficiencies 
could result in a customer terminating our contract for cause or could otherwise result in our default under the applicable 
14

contract. A termination for cause or other default could expose us to liability, damage our reputation and substantially impair 
our ability to compete for future contracts and orders.
Some of our contracts contain late delivery penalties. Our failure to deliver our products in a timely manner, whether due to 
supplier and supply chain problems, labor availability, development schedule slides, manufacturing difficulties, similar 
schedule-related events or otherwise, may trigger late delivery penalties pursuant to certain of our contracts, which could 
materially adversely affect our business, financial condition and results of operations. While no significant penalties have been 
incurred to date, the risk factors described herein may cause future deliveries to be delayed and may cause us to incur such 
significant penalties in the future.
Our results of operations are affected by our fixed-price contracts, which could subject us to losses in the event that we 
have cost overruns. For the year ended December 31, 2024, fixed-price contracts represented almost all of the Company’s 
sales. On fixed-price contracts, we agree to perform the scope of work specified in the contract for a predetermined price. 
Depending on the fixed price negotiated, these contracts may provide us with an opportunity to achieve higher profits based on 
the relationship between our costs and the contract’s fixed price. However, we bear the risk that increased or unexpected costs, 
such as contractual delays, failure of subcontractor performance, litigation with contract counterparties, inaccurate cost 
estimates or otherwise, may reduce our profit or cause us to incur a loss on the contract, which could reduce our net earnings. 
Because our ability to terminate contracts is generally limited, we may not be able to terminate our performance requirements 
under these contracts at all or without substantial liability and, therefore, in the event we are sustaining reduced profits or losses, 
we could continue to sustain these reduced profits or losses for the duration of the contract term. Our failure to anticipate 
technical problems, estimate delivery reductions, estimate costs accurately or control costs during performance of a fixed-price 
contract may reduce our profitability or cause significant losses on programs.
The failure of our products may damage our reputation, necessitate a product recall or result in claims against us that 
exceed our insurance coverage, thereby requiring us to pay significant damages. Defects in the design and manufacture of 
our products may necessitate a product recall. We include complex system design and components in our products that could 
contain errors or defects, particularly when we incorporate new technology into our products. If any of our products are 
defective, we could be required to redesign or recall those products or pay substantial damages or warranty claims. Such an 
event could result in significant expenses, disrupt sales and affect our reputation and that of our products. We are also exposed 
to product liability claims. We carry aircraft and non-aircraft product liability insurance consistent with the commercial 
standards in our industry. However, this insurance coverage may not be sufficient to fully cover the payment of any potential 
claim. Additionally, should insurance market conditions change, aircraft and non-aircraft product liability insurance coverage 
may not be available in the future at a cost acceptable to us. A product recall or a product liability claim not covered by 
insurance could materially adversely affect our business, liquidity, financial condition and results of operations.
Our operations depend on our manufacturing facilities, which are subject to physical and other risks that could disrupt 
production. Our manufacturing facilities or our customers’ facilities could be damaged or disrupted by a natural disaster, war, 
or terrorist activity. We maintain property damage and business interruption insurance consistent with the commercial standards 
in our industry or for our customers and suppliers, however, a pandemic or other major catastrophe, such as an earthquake, 
hurricane, fire, flood, tornado or other natural disaster at any of our sites, or political instability resulting from war, 
insurrections, terrorist activities, foreign civil unrest or other unforeseen circumstances in any of the areas where we conduct 
operations could result in a prolonged interruption of our business. Any disruption resulting from these events could cause 
significant delays in shipments of products and the loss of sales and customers, and we may not have insurance to adequately 
compensate us for any of these events. For leased facilities, timely renewal of leases and risk mitigation from the sale of our 
leased facilities is required to avoid any business interruption.
We may be subject to work stoppages at our facilities or those of our principal customers and suppliers, which could 
seriously impact the profitability of our business. Many aircraft manufacturers, airlines, and aerospace suppliers have 
unionized work forces. Any strikes, work stoppages, or slowdowns experienced by aircraft manufacturers, airlines, or aerospace 
suppliers could reduce our customers’ demand for additional aircraft structures or prevent us from completing production of our 
products.
A small percentage of our workforce is represented by unions. If we were unable to renew our labor agreements at expiration, 
or if our workers were to engage in a strike, work stoppage, or other slowdown, we could experience a disruption of our 
operations, which could cause us to be unable to deliver products to certain of our customers on a timely basis and could result 
in a breach of such supply agreements. This could negatively impact our results. In addition, our non-unionized labor force may 
become subject to labor union organizing efforts, which could cause us to incur additional labor costs and increase the related 
risks that we now face.
15

The construction of aircraft is heavily regulated, and failure to comply with applicable laws could reduce our sales or 
require us to incur additional costs to achieve compliance, and we may incur significant expenses to comply with new or 
more stringent governmental regulation. The aerospace industry is highly regulated in the United States by the FAA and in 
other countries by similar agencies. We must be certified by the FAA and, in some cases, by individual OEMs in order to 
engineer and service parts, components and aerostructures used in specific aircraft models. If any of our material authorizations 
or approvals were revoked or suspended, our operations would be adversely affected. New or more stringent governmental 
regulations may be adopted, or industry oversight heightened in the future, and we may incur significant expenses to comply 
with any new regulations or any heightened industry oversight. In addition, in January 2024, the FAA ordered the temporary 
grounding of Boeing 737-9 MAX aircraft as a result of an incident where a Boeing 737-9 MAX lost a “door plug.” This 
incident and the subsequent investigation, and the potential for more issues to be identified during further investigations, could 
result in a suspension or reduction of manufacturing of 737 MAX aircraft by Boeing. Air travelers may also respond negatively 
to the 737 MAX aircraft due to perceived safety concerns, which could negatively impact Boeing. Boeing is a major customer 
of ours and any financial or customer losses it suffers may result in a negative impact on our business, financial condition and 
results of operations.
In addition, recent U.S. government administrations have relied on executive orders in lieu of federal legislation to implement 
regulatory policy and objectives, and the U.S. Supreme Court has recently issued decisions that have added uncertainty to the 
federal regulatory apparatus. Each of these developments could exacerbate regulatory unpredictability. We may be unable to 
anticipate changes in regulatory regimes of the U.S. federal government administration and, therefore, be unable to make timely 
operational or other changes, assuming we are in a position to effectively respond to any such change, which may not be the 
case, or to ensure compliance with federal regulations or executive orders. Executive orders or regulatory priorities issued or 
rescinded by the U.S. federal government administration may require us to make additional capital expenditures or incur 
additional costs, or cause a delay or the abandonment of projects or awarded contracts, which could materially adversely affect 
our business, results of operations and financial condition In addition, increased regulatory uncertainty following the 
forementioned U.S. Supreme Court decisions could result in delays and other impediments to the federal agency rulemaking 
process, which could materially adversely affect our business, results of operations and financial condition
Financial Risks
We have incurred losses in prior fiscal years and our future profitability is not certain. For the years ended December 31, 
2024, 2023 and 2022, we incurred a net loss of $16.2 million, $26.4 million and $35.7 million, respectively. Our operating 
results for future periods are subject to numerous uncertainties and we cannot be certain that we will be profitable or that we 
will not experience substantial net losses in the future. If we are not able to increase revenue or reduce our costs, we may not be 
able to achieve profitability in future periods and our business, financial condition, results of operations and cash flows may be 
materially adversely affected.
Our ABL Revolving Credit Facility contains financial and restrictive covenants that we may be unable to satisfy, and 
that, if not satisfied, could result in the acceleration of any outstanding indebtedness thereunder and limit our ability to 
borrow additional funds. In addition, the terms of our ABL Revolving Credit Facility contains covenants that restrict 
our current and future operations, particularly our ability to take certain actions. Our ABL Revolving Credit Facility 
subjects us to various financial and other affirmative and negative covenants with which we must comply on an ongoing or 
periodic basis. These include financial covenants pertaining to minimum excess availability and minimum fixed charge 
coverage ratio requirements. An unexpected decline in our revenues or operating income, including occurring as a result of 
events beyond our control, could cause us to violate our financial covenants. A covenant violation could result in a default 
under the ABL Revolving Credit Facility. If any such default occurs, the lenders may elect to declare all outstanding 
borrowings, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. Further, 
as the amount available to us under our ABL Revolving Credit Facility is subject to borrowing base calculations determined by 
the value of accounts receivable, inventory, real estate and machinery and equipment, an unexpected decline in the value of 
these assets would require a mandatory prepayment. If any of these events were to occur, we may not be able to pay our debts 
and other monetary obligations as they come due, and our ability to continue to operate as a going concern could be impaired, 
which could in turn cause a significant decline in our common stock price and could result in a significant loss of value for our 
shareholders. Furthermore, the lenders also have the right in these circumstances to terminate any commitments they have to 
provide further borrowings, which could leave us without access to sufficient liquidity to operate our business. In addition, 
following an event of default, the lenders under the ABL Revolving Credit Facility will have the right to proceed against the 
collateral granted to them to secure the debt, which includes our available accounts receivable, inventory, machinery and 
equipment, real estate and intellectual property. If the debt under the ABL Revolving Credit Facility were to be accelerated, we 
cannot assure you that our assets would be sufficient to repay in full our debt.
Additionally, our ABL Revolving Credit Facility contains a number of restrictive covenants that impose significant operating 
and financial restrictions on the Company and our subsidiaries and may limit our ability to engage in acts that we believe to be 
16

in our long-term best interests. The ABL Revolving Credit Facility include covenants restricting, among other things, the ability 
of the Company and our subsidiaries to:
•
incur additional indebtedness;
•
pay dividends on or repurchase our capital stock;
•
make certain acquisitions or investments;
•
sell assets; and
•
engage in certain business activities.
Our inability to raise funds necessary to repurchase, or settle conversions of, our Convertible Notes upon a fundamental 
change as described in the indenture governing the Convertible Notes, may lead to defaults under such indenture and 
under agreements governing our existing or future indebtedness. On December 3, 2024, we issued an aggregate principal 
amount of $165 million 5.500% Convertible Notes due March 15, 2030, unless earlier converted, redeemed or repurchased. The 
interest rate is fixed at 5.500% per annum and is payable semi-annually in arrears on March 15 and September 15 of each year, 
beginning on March 15, 2025. 
If a fundamental change (as defined in the indenture governing the Convertible Notes) occurs, then, subject to limited 
exceptions, holders of our Convertible Notes may require the Company to repurchase all or any their Convertible Notes for 
cash. If we repurchase the Convertible Notes for cash or settle such Convertible Notes by cash or by a combination of cash and 
shares of our common stock in the event a holder of our Convertible Notes elects to convert their Convertible Notes following a 
fundamental change, we will be required to make cash payments with respect to the Convertible Notes being converted or 
repurchased.
However, we may not have enough available cash or be able to obtain financing at the time we are required to make purchases 
of the Convertible Notes being surrendered or converted. In addition, our ability to repurchase the Convertible Notes or to pay 
cash upon conversion of Convertible Notes is limited by the ABL Revolving Credit Facility and may also be limited by law, by 
regulatory authority or by agreements that will govern our future indebtedness. Our failure to repurchase Convertible Notes at a 
time when the repurchase is required by the indenture governing the Convertible Notes or to pay cash payable on future 
conversions of the Convertible Notes as required by such indenture would constitute a default under such indenture. A default 
under the indenture governing the Convertible Notes or the fundamental change itself could also lead to a default under the 
ABL Revolving Credit Facility.
The conditional conversion feature of the Convertible Notes, if triggered, may adversely affect our financial condition 
and operating results. Under certain circumstances, holders of our Convertible Notes will be entitled to convert such 
Convertible Notes at any time during specified periods at their option. If one or more holders of our Convertible Notes elect to 
convert their Convertible Notes, we may initially elect to satisfy our conversion obligations by combination settlement. In 
addition, in the future, we may elect to settle all of our conversion obligations through the payment of cash, which could 
materially adversely affect our liquidity. In addition, even if holders do not elect to convert their Convertible Notes, we could be 
required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Convertible Notes as 
a current liability, rather than a long-term liability, which could result in a material reduction of our net working capital.
Conversion of the Convertible Notes will dilute the ownership interest of existing shareholders or may otherwise depress 
the price of our common stock. The conversion of some or all of the Convertible Notes will dilute the ownership interests of 
existing shareholders to the extent we deliver shares of our common stock upon conversion of any of the Convertible Notes. 
The Convertible Notes may from time to time in the future be convertible at the option of their holders prior to their scheduled 
terms under certain circumstances. Any sales in the public market of the common stock issuable upon such conversion could 
adversely affect prevailing market prices of our common stock. In addition, the existence of the Convertible Notes may 
encourage short selling by market participants because the conversion of the Convertible Notes could be used to satisfy short 
positions or anticipated conversion of the Convertible Notes into shares of our common stock could depress the price of our 
common stock.
The amount of debt we have outstanding, as well as any debt we may incur in the future, could have an adverse effect on 
our operational and financial flexibility. As of December 31, 2024, we had approximately $175.0 million of debt outstanding. 
Changes to our level of debt subsequent to December 31, 2024, could have significant consequences to our business, including 
the following:
•
Depending on interest rates and debt maturities, a substantial portion of our cash flow from operations could be 
dedicated to paying principal and interest on our debt, thereby reducing funds available for our acquisition strategy, 
capital expenditures or other purposes;
•
A significant amount of additional debt could make us more vulnerable to changes in economic conditions or increases 
in prevailing interest rates;
17

•
Our ability to obtain additional financing for acquisitions, capital expenditures or for other purposes could be impaired;
•
The increase in the amount of debt we have outstanding and the associated interest expense increases the risk of non-
compliance with some of the covenants in our debt agreements which require us to maintain specified financial ratios; 
and
•
We may be more leveraged than some of our competitors, which may result in a competitive disadvantage.
Subject to the limits contained in our ABL Revolving Credit Facility, we may incur additional debt from time to time to finance 
working capital, capital expenditures, investments or acquisitions, or for other purposes. If we do so, the risks described above 
related to our debt could intensify.
A write-off of all or part of our goodwill or other intangible assets could adversely affect our operating results and net 
worth. As of December 31, 2024, goodwill and net intangible assets were approximately 8.9% and 8.1% of our total assets, 
respectively. We had no goodwill impairment charges during 2024, 2023 or 2022. Our goodwill and other intangible assets may 
increase in the future since our strategy includes growing through acquisitions. We may have to write-off all or part of our 
goodwill or purchased intangible assets if their value becomes impaired. Although such a write-off may not result in an outlay 
of cash and is not included in the financial covenant calculation, it could reduce our earnings and net worth significantly.
Our future operating results could be impacted by estimates used to calculate impairment losses on goodwill and long-
lived assets. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires 
management to make significant and subjective estimates and assumptions that may affect the reported amounts of tangible and 
intangible long-lived assets, including goodwill, in the Consolidated Financial Statements. These estimates are integral in the 
determination of whether a potential non-cash impairment loss exists as well as the calculation of that loss. Actual future results 
could differ materially from those estimates. We had no such asset impairment charges in 2024, 2023 or 2022.
Changes in discount rates and other estimates could affect our future earnings and equity. Our goodwill asset impairment 
evaluations are determined using valuations that involve several assumptions, including discount rates, cash flow estimates, 
growth rates and terminal values. Certain of these assumptions, particularly the discount rate, are based on market conditions 
and are outside of our control. Changes in these assumptions could affect our future earnings and equity.
Additionally, pension obligations and the related costs are determined using actual results and actuarial valuations that involve 
several assumptions. The most critical assumption is the discount rate. Other assumptions include mortality, salary and bonus 
levels and retirement age. The discount rate assumptions are based on current market conditions and are outside of our control. 
Changes in these assumptions could affect our future earnings and equity. 
Changes in tax laws and regulations or exposure to additional tax liabilities could adversely affect our financial results. 
Changes in U.S. (federal or state) or foreign tax laws and regulations, or their interpretation and application, including those 
with retroactive effect, could result in increases in our tax expense and affect profitability and cash flows. For example, 
beginning in 2022, the Tax Cuts and Jobs Act of 2017 eliminated the option to deduct research and development expenditures 
immediately in the year incurred and requires taxpayers to amortize such expenditures over five years for tax purposes. The 
most significant impact of this provision is to the cash tax liability for 2024 and 2023 (as the liability for 2022 is partially offset 
by certain tax credits and loss carryforwards); the impact will decline annually thereafter over the five-year amortization period 
to an immaterial amount in year six. Furthermore, compliance with the tax regimes we are subject to is difficult and expensive. 
If we fail to adhere, or are alleged to have failed to adhere, to any applicable federal, state, or foreign laws or regulations, or if 
such laws or regulations negatively affect sales of our products, our business, financial condition and results of operations may 
be materially adversely affected. In addition, our future results could be materially adversely affected by changes in applicable 
federal, state, and foreign laws and regulations, or the interpretation or enforcement thereof (including tax-rate changes, new tax 
laws such as the proposed 15% global minimum tax under the Organisation for Economic Co-operation and Development Pillar 
Two, Global Anti-Base Erosion Rules, or revised tax law interpretations).
We are subject to financing and interest rate exposure risks that could adversely affect our business, liquidity and 
operating results. Changes in the availability, terms and cost of capital, and increases in interest rates could cause our cost of 
doing business to increase and place us at a competitive disadvantage. At December 31, 2024, the $10.0 million outstanding on 
our ABL Revolving Credit Facility is subject to variable interest rates.

Legal and Compliance Risks
We currently are involved in, and may become involved in the future in, legal proceedings that, if adversely adjudicated 
or settled, could materially and adversely impact our financial condition. As an aerospace company, we may become a 
party to litigation, including, among others, matters alleging product liability, warranty claims, intellectual property 
infringement, breach of commercial or government contract or other legal actions. In general, litigation claims can be expensive 
and time consuming to bring or defend against and could result in settlements or damages that could materially adversely affect 
our results of operations and financial condition. For example, in some instances, litigation may be necessary to enforce our 
intellectual property rights and protect our proprietary information, or to defend against claims by third parties that our products 
infringe upon their intellectual property rights. Any litigation or claims brought by or against us, whether with or without merit, 
could result in substantial costs to us and divert the attention of our management, which could materially harm our business and 
results of operations. In addition, any intellectual property litigation or claims against us could result in the loss or compromise 
of our intellectual property and proprietary rights, subject us to significant liabilities, require us to seek licenses on unfavorable 
terms, expose us to injunctive relief, prevent us from manufacturing or selling certain products or require us to redesign certain 
products, any of which could materially adversely affect our results of operations and financial condition.
Currently, our subsidiary, Astronics Advanced Electronic Systems Corp., is a defendant in actions filed in various 
jurisdictions by Lufthansa Technik AG relating to an allegation of patent infringement and based on rulings to date, we 
have concluded that losses related to these proceedings are probable and the amounts of such losses could be substantial. 
Lufthansa Technik AG (“Lufthansa”) filed actions against us in Germany, the UK and France. In both Germany and the UK, 
the Company has been found to infringe the patents of Lufthansa and will be subject to monetary damages and estimates of 
which have been accrued as liabilities in our financial statements. However, the actual amount of damages that may be 
addressed in the future could be substantially higher than the amounts that have been accrued as liabilities in our financial 
statements. In February 2025, a judgment quantified the amount payable in aggregate in respect of the profits derived from 
infringing Lufthansa’s UK patent by the defendants as $11.9 million. Any additional amounts required to be paid by the 
Company related to certain other factors peripheral to the damages award, including reimbursement of legal fees related to the 
damages proceedings, will be determined at follow-up hearings expected to occur in the first half of 2025. An appeal, if any, 
would likely be heard in early 2026. 
Refer to Note 19, Legal Proceedings, of our Consolidated Financial Statements in Item 8, Financial Statements and 
Supplementary Data, of this report for discussion on this and other legal proceedings.
Our operations in foreign countries expose us to political and currency risks and adverse changes in local legal and 
regulatory environments. In 2024, approximately 10% of our sales were made by our subsidiaries in foreign countries, 
predominately in our subsidiaries in France and Canada. Net assets held by our foreign subsidiaries total $41.3 million as of 
December 31, 2024. Approximately 25% of our consolidated sales in 2024 were made to customers outside of the United 
States. Our financial results may be adversely affected by fluctuations in foreign currencies and by the translation of the 
financial statements of our foreign subsidiaries from local currencies into U.S. dollars. We expect international operations and 
export sales to continue to contribute to our earnings for the foreseeable future. Both the sales from international operations and 
export sales are subject in varying degrees to risks inherent in doing business outside of the U.S. Such risks include the 
possibility of unfavorable circumstances arising from host country laws or regulations, changes in tariff and trade barriers and 
import or export licensing requirements, and political or economic reprioritization, insurrection, civil disturbance or war.
Government regulations could limit our ability to sell our products outside the U.S. and could otherwise adversely affect 
our business. Certain of our sales are subject to compliance with U.S. export regulations. Our failure to comply with the 
regulatory limitations, licensing requirements, registration standards or other requirements under applicable U.S. export 
regulations would hinder our ability to generate sales of our products outside the U.S. Compliance with these export regulations 
may also subject us to additional fees and operating costs. The absence of comparable restrictions on competitors in other 
countries may adversely affect our competitive position. In order to sell our products in European Union countries, we must 
satisfy certain technical requirements. If we are unable to comply with those requirements with respect to a significant quantity 
of our products, our sales in Europe could be restricted. Doing business internationally also subjects us to numerous U.S. and 
foreign laws and regulations, including regulations relating to import-export control, technology transfer restrictions, foreign 
corrupt practices and anti-boycott provisions. Our failure, or failure by an authorized agent or representative that is attributable 
to us, to comply with these laws and regulations could result in administrative, civil or criminal liabilities and could, in the 
extreme case, result in monetary penalties, suspension or debarment from government contracts or suspension of our export 
privileges, which could materially adversely affect our business, financial condition and results of operations.
Trade policies, treaties, and tariffs could materially adversely affect our business. Our business is dependent on the 
availability of raw materials and components for our products, particularly electrical components common in the semiconductor 
industry. There is continued uncertainty about the future relationship between the United States and various other countries, 
19

most significantly China, with respect to trade policies, treaties, tariffs, and taxes. Changes in U.S. administrative policy could 
lead to changes in existing trade agreements, greater restrictions on free trade generally, and significant increases in tariffs on 
goods imported into the United States, particularly tariffs on products manufactured in Canada, China and Mexico, among other 
possible changes. For example, in February 2025, the new U.S. presidential administration announced tariffs on imports from 
Canada, Mexico and China, and then subsequently paused the tariffs on Canada and Mexico. It is uncertain whether the tariffs 
on Canada and Mexico will be reinstated. These developments, or the perception that any of them could occur, could materially 
adversely affect global economic conditions and the stability of global financial markets, and could significantly reduce global 
trade and, in particular, trade between the impacted nations and the United States.
This uncertainty includes: (i) the possibility of altering the existing tariffs or penalties on products manufactured outside the 
United States, including the U.S. government’s 25% tariff on a range of products from China; (ii) the effects stemming from the 
removal of such previously imposed tariffs; (iii) subsequent tariffs imposed by the United States on any other countries; and 
(iv) potential tariffs imposed by trading partners on U.S. exports. The institution of trade tariffs on items imported by us from 
other countries could increase our costs, which could have a negative impact on our business.
We cannot predict whether, and to what extent, there may be changes to international trade agreements or whether quotas, 
duties, tariffs, exchange controls or other restrictions on our products will be changed or imposed. In addition, an open conflict 
or war across any region could affect our ability to obtain raw materials. For example, the current military conflict between 
Russia and Ukraine, and related sanctions, export controls or other actions that may be initiated by nations, including the United 
States, the European Union or Russia (e.g., potential cyberattacks, disruption of energy flows, etc.) or potential sanctions or 
relevant export controls related to China or Taiwan could adversely affect our business and/or our supply chain or our business 
partners or customers in other countries beyond Russia and Ukraine. Although we currently maintain alternative sources for raw 
materials, if we are unable to source our products from the countries where we wish to purchase them, either because of the 
occurrence or threat of wars or other conflicts, regulatory changes or for any other reason, or if the cost of doing so increases, it 
could materially adversely affect our business, financial condition and results of operations. Disruptions in the supply of raw 
materials and components could temporarily impair our ability to manufacture our products for our customers or require us to 
pay higher prices to obtain these raw materials or components from other sources, which could materially adversely affect our 
business and our results of operations.
We may face reputational, regulatory or financial risks from a perceived, or an actual, failure to achieve our 
sustainability goals. The increased focus on sustainability practices and disclosures is rapidly evolving, as is the criteria to 
measure our sustainability performance; both of which could result in greater expectations and may cause us to undertake costly 
initiatives to satisfy the evolving criteria. As we advance our sustainable business model, we are pursuing programs that we 
believe will improve our environmental practices, social engagement and how we govern ourselves. We periodically publish 
information about our sustainability goals, standards and frameworks. Achievement of these objectives is subject to risks and 
uncertainties, many of which are outside of our direct control, and it is possible we may fail, or be perceived to have failed, in 
the achievement of our sustainability goals. Also, certain customers, associates, shareholders, investors, suppliers, business 
partners, government agencies and non-governmental organizations may not be satisfied with our sustainability efforts. A 
failure or perceived failure of our sustainability goals could negatively affect our reputation and our results of operations.
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. Department of Defense (“USDOD”). 
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 materially adversely affect 
our financial results.
We are subject to the requirements of the National Industrial Security Program Operating Manual for facility security 
clearance, which is a prerequisite for our ability to perform on classified contracts for the U.S. Government. USDOD 
facility security clearance is required in order to be awarded and be able to perform on classified contracts for the USDOD and 
certain other agencies of the U.S. Government, which is a significant part of our business. We have obtained clearance at 
appropriate levels that require stringent qualifications, and we may be required to seek higher level clearances in the future. We 
cannot assure you that we will be able to maintain our security clearance. If for some reason our security clearance is 
invalidated or terminated, we may not be able to continue to perform our present classified contracts or be able to enter into new 
classified contracts, which could affect our ability to compete for and capture new business.
20

Our business is subject to regulation in the United States and internationally. The manufacturing of our products is subject 
to numerous federal, state and foreign governmental regulations. The number of laws and regulations that are being enacted or 
proposed by various governmental bodies and authorities is increasing. Compliance with these regulations is difficult and 
expensive. If we fail to adhere, or are alleged to have failed to adhere, to any applicable federal, state, or foreign laws or 
regulations, or if such laws or regulations negatively affect sales of our products, our business, prospects, results of operations, 
financial condition or cash flows may be adversely affected. In addition, our future results could be adversely affected by 
changes in applicable federal, state, and foreign laws and regulations, or the interpretation or enforcement thereof, including 
those relating to manufacturing processes, product liability, government contracts, trade rules and customs regulations, 
intellectual property, consumer laws, privacy laws, environmental protection, climate change, as well as accounting standards 
and taxation requirements (including tax-rate changes, new tax laws or revised tax law interpretations).
General Risks
Our future success depends to a significant degree upon the continued contributions of our management team and 
technical personnel. Our ability to hire new talent, develop existing talent and to retain our management team and other key 
personnel is critical to our success. The loss of members of our management team could materially adversely affect our 
business. In addition, competition for qualified technical personnel in our industry is intense, and we believe that our future 
growth and success will depend on our ability to attract, train and retain such qualified personnel. If we are unable to retain our 
management team, maintain and develop our key personnel and attract new qualified employees, the execution of our business 
strategy may be hindered and our growth limited.
If we fail to meet expectations of securities analysts or investors due to fluctuations in our sales or operating results, our 
stock price could decline significantly. Our sales and earnings may fluctuate from quarter to quarter due to a number of 
factors, including delays or cancellations of programs and supply chain challenges on revenues and costs. It is likely that in 
some future quarters our operating results may fall below the expectations of securities analysts or investors. In this event, the 
trading price of our stock could decline significantly.
Our stock price is volatile. For the year ended December 31, 2024, our stock price ranged from a low of $15.59 to a high of 
$23.39. The price of our common stock has been and likely will continue to be subject to wide fluctuations in response to a 
number of events and factors, such as:
•
our ability to comply with the financial and other affirmative and negative covenants included in our ABL Revolving 
Credit Facility;
•
quarterly variations in operating results;
•
variances of our quarterly results of operations from securities analyst estimates;
•
changes in financial estimates;
•
announcements of technological innovations and new products;
•
news reports relating to trends in our markets or adverse happenings at our customers; and
•
the cancellation of major contracts or programs with our customers;
In addition, the stock market in general, and the market prices for companies in the aerospace and defense industry in particular, 
have experienced significant price and volume fluctuations that often have been unrelated to the operating performance of the 
companies affected by these fluctuations. These broad market fluctuations may adversely affect the market price of our 
common stock, regardless of our operating performance. Global health crises, such as the recent COVID-19 pandemic, with the 
breadth of its impact worldwide, and particularly on the aerospace industry, could also cause significant volatility in the market 
price.

CYBERSECURITY
We recognize the critical importance of assessing, identifying, and managing material risks associated with cybersecurity 
threats. Our cybersecurity strategy prioritizes detection, analysis and response to known, anticipated or unexpected threats, 
effective management of security risks, and resiliency against incidents. This strategy is supported by both management and our 
Board of Directors.
We continuously strive to surpass industry best practices by implementing risk-based controls aimed at safeguarding both our 
partners’ and the Company’s information systems. In order to protect both commercial and defense-related businesses and 
support our production operations, the Company has adopted security principles in accordance with the National Institute of 
21

Standards and Technology Cybersecurity Framework, contractual requirements and other global standards. We conduct annual 
security assessments, including external and internal penetration tests, social engineering attacks, and vulnerability assessments. 
These assessments provide critical insights into our security posture and help us identify and seek to address potential 
weaknesses proactively. We leverage multiple vendors and their diverse perspectives as means to enhance the effectiveness of 
our security measures. Furthermore, as we implement solutions, we engage with industry-leading partners to receive guidance 
on best practices for solution use and overall security. This collaboration seeks to align our cybersecurity strategies with the 
latest industry standards and best practices. We also maintain regular communication with external partners to stay abreast of 
current cybersecurity trends and emerging threats. This proactive approach enables us to seek to enhance our security posture 
and adapt our defenses to evolving cyber risks. 
The Company’s Director of Information Technology (“IT”), who reports to our CFO, has over 20 years of experience leading 
cyber security oversight and is responsible for management of cybersecurity risk and the protection and defense of our networks 
and systems. Our IT security team, led by the Director of IT, consists of professionals with broad cybersecurity experiences, 
including a number of cybersecurity certifications and degrees. As a result, our IT security teams utilize their understanding of 
industry best practices and hands-on experience to seek to implement effective cybersecurity solutions. Cybersecurity remains a 
top priority across the organization, with resources allocated in an efficient manner to seek to mitigate risks and enhance our 
overall security posture.
The Board of Directors oversees an enterprise-wide approach to risk management, designed to support the achievement of 
organizational objectives, including strategic objectives, to improve long-term organizational performance and enhance 
shareholder value. The Director of IT provides a report to the Board of Directors on an annual basis, or more frequently as 
needed, with respect to information security activity, security assessments, controls and investments.
We have a set of Company-wide policies and procedures concerning cybersecurity matters. The Company’s Incident 
Management Policy provides a framework for reporting and managing security incidents affecting the Company’s information 
and business computing devices and systems, losses of information, and information security concerns. All users, including 
employees, contractors, consultants, suppliers, customers, government, and all personnel affiliated with third parties that 
perform work for the Company, are obligated to report information security incidents in order to mitigate the consequences and 
reduce the risk of future breaches of security. Our incident response process consists of several principal steps, including 1) 
preparation for a cybersecurity incident, 2) detection of a security incident and assignment to the appropriate IT personnel, 3) 
identification and preservation of evidence, and 4) risk assessment. Depending on the nature and severity of an incident, 
notifications are escalated to our CEO and the Board of Directors and, if determined to be material, externally. The incident 
management process is overseen by the Director of IT. The Company maintains additional policies that directly or indirectly 
relate to cybersecurity, such as policies related to encryption standards, mobile devices and data destruction. These policies go 
through an internal review process and are approved by appropriate members of management. 
Our IT security team reviews enterprise risk management-level cybersecurity risks annually. The following key risk elements 
are evaluated:
•
Insiders – Whether intentional or unintentional, individuals within our Company may cause damage to our systems. 
We have processes in place to seek to mitigate these threats, including through controls over access to our systems and 
access to network resources. 
•
External threats – We recognize the risk that hackers, vandals, and saboteurs may seek to gain access to information 
contained in our systems. We employ multi-layered defense and monitoring to seek to mitigate the risk associated with 
these threats. The Company also conducts regular periodic training of its employees as to the protection of sensitive 
information which includes security awareness training intended to prevent the success of “phishing” attacks.
•
Third-party risks – We also consider and evaluate cybersecurity risks associated with use of third-party service 
providers. User access to third-party systems is reviewed annually, and we obtain and review a System and 
Organization Controls (“SOC”) 1 or SOC 2 report from key third-party service providers.
Key cybersecurity risks and mitigating responses are addressed within our Company-wide policies. 
While we have experienced cybersecurity incidents in the past, to date none have materially affected the Company or our 
financial position, results of operations and/or cash flows. However, the risks from cybersecurity threats and incidents continue 
to increase, and the preventative actions we have taken and continue to take to reduce the risk of cybersecurity threats and 
incidents may not successfully protect against all such threats and incidents. We continue to invest in the cybersecurity and 
resiliency of our networks and to enhance our internal controls and processes, which are designed to help protect our systems 
and infrastructure, and the information they contain. For more information regarding the risks we face from cybersecurity 
threats, please see Item 1A, Risk Factors, under the heading “Our business and operations could be adversely impacted in the 
event of a failure of our information technology infrastructure or adversely impacted by a successful cyber-attack.”

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS
OVERVIEW
Astronics Corporation, through its subsidiaries, is a leading supplier of advanced technologies and products to the global 
aerospace and defense industries. Our products and services include advanced, high-performance electrical power generation 
and distribution systems, seat motion solutions, lighting and safety systems, avionics products, aircraft structures, systems 
certification, and automated test systems.
We have two reportable segments, Aerospace and Test Systems. Our Aerospace segment has principal operating facilities in the 
United States, Canada and France and an engineering office in Ukraine. Our Test Systems segment has principal operating 
facilities in the United States and an engineering office in India.
Our Aerospace segment designs and manufactures products for the global aerospace industry. Product lines include lighting and 
safety systems, electrical power generation, distribution and seat motion systems, aircraft structures, avionics products, systems 
certification, and other products. Our primary Aerospace customers are the airframe manufacturers (“OEM”) that build aircraft 
for the commercial transport, military and general aviation markets, suppliers to those OEMs, aircraft operators such as airlines, 
suppliers to the aircraft operators, and branches of the U.S. Department of Defense (“USDOD”). Our Test Systems segment 
designs, develops, manufactures and maintains automated test systems that support the aerospace and defense and mass transit 
industries as well as training and simulation devices for both commercial and military applications. In the Test Systems 
segment, Astronics’ products are sold to a global customer base including OEMs and prime government contractors for both 
electronics and military products. 
Our strategy is to increase our value by developing technologies and capabilities, either internally or through acquisition, and 
using those capabilities to provide innovative solutions to our targeted markets where our technology can be beneficial.
Important factors affecting our growth and profitability are the rate at which new aircraft are produced, government funding and 
timing of awards of military programs, our ability to have our products designed into new aircraft, the rates at which aircraft 
owners, including commercial airlines, refurbish or install upgrades to their aircraft and supply chain and labor market 
pressures. New aircraft build rates and aircraft owners spending on upgrades and refurbishments is cyclical and dependent on 
the strength of the global economy. Once one of our products is designed into a new aircraft, the spare parts business associated 
thereto is also frequently retained by the Company. Future growth and profitability of the Test Systems business is dependent 
on developing and procuring new and follow-on business. The nature of our Test Systems business is such that it pursues large, 
often multi-year, projects. There can be significant periods of time between orders in this business, which may result in large 
fluctuations of sales and profit levels and backlog from period to period. Test Systems segment customers include the USDOD, 
prime contractors to the USDOD, mass transit operators and prime contractors to mass transit operators.
Each of the markets that we serve presents opportunities that we expect will provide growth for the Company over the long-
term. We continue to look for opportunities in all of our markets to capitalize on our core competencies to expand our existing 
business and to grow through strategic acquisitions.
The main challenges that we continue to face include varying levels of supply chain pressures, material availability and cost 
increases (including tariffs), labor availability and cost, and improving shareholder value through increasing profitability. 
Increasing profitability is dependent on many things, primarily sales growth, both acquired and organic, and the Company’s 
ability to pass cost increases along to customers and control operating expenses, and to identify means of creating improved 
25

productivity. Sales are driven by increased build rates for existing aircraft, market acceptance and economic success of new 
aircraft and our products, continued government funding of defense programs, the Company’s ability to obtain production 
contracts for parts we currently supply or have been selected to design and develop for new aircraft platforms and continually 
identifying and winning new business for our Test Systems segment. 
Reduced aircraft build rates driven by regulatory actions impacting OEM production, a weak economy, aircraft groundings, 
tight credit markets, reduced air passenger travel, and an increasing supply of used aircraft on the market would likely result in 
reduced demand for our products, which will result in lower profits. Reduction of defense spending may result in fewer 
opportunities for us to compete, which could result in lower profits in the future. Many of our newer development programs are 
based on new and unproven technology and at the same time we are challenged to develop the technology on a schedule that is 
consistent with specific programs. Delays in delivery schedules and incremental costs resulting from supply chain, tariff and 
labor rate pressures have in the past resulted, and could in the future also result in, lower profits. We will continue to address 
these challenges by working to improve operating efficiencies and focusing on executing on the growth opportunities currently 
in front of us.
Our ABL Revolving Credit Facility subjects us to various financial and other affirmative and negative covenants with which we 
must comply on an ongoing or periodic basis. These include financial covenants pertaining to minimum excess availability 
requirements and minimum fixed charge coverage ratio requirements. An unexpected decline in our revenues or operating 
income, including occurring as a result of events beyond our control, could cause us to violate our financial covenants. While 
the Company expects to remain in compliance with the required financial covenants for the duration of the agreements, any 
unexpected negative impacts to our business, including as a result of declines in aircraft production rates from expectations or 
production delays resulting from regulatory actions or labor strikes affecting OEMs, additional supply chain pressures, the 
timing of customer orders, and our ability to meet customer delivery schedules, or labor availability and cost pressures, could 
result in lower revenues and reduced financial profits, and, as a result thereof, our inability to satisfy the financial covenants in 
our ABL Revolving Credit Facility. 
Challenges affecting the commercial aviation industry or key participants can adversely impact the demand for our products and 
services, the timing of orders, deliveries and related payments and other factors. We are monitoring the production and other 
challenges at The Boeing Company, including the recently resolved strike, and we continue to align with them on production 
expectations.
See Item 1A, Risk Factors, of this report for an additional discussion of risks associated with our potential inability to satisfy 
the financial and restrictive covenants set forth in the ABL Revolving Credit Facility.
In September 2021, the Company was awarded a grant of up to $14.7 million from the U.S. Department of Transportation 
(“USDOT”) under the Aviation Manufacturing Jobs Protection Program (“AMJP”). The Company received $7.3 million under 
the grant in 2022. The grant benefit was recognized ratably over the six-month performance period as a reduction to Cost of 
Products Sold in proportion to the compensation expense that the award was intended to defray. During the year ended 
December 31, 2022, the Company recognized $6.0 million of the award.
We are monitoring the ongoing conflict between Russia and Ukraine and the related export controls and financial and economic 
sanctions imposed on certain industry sectors, including the aviation sector, and parties in Russia by the U.S., the U.K., the 
European Union and others. Although the conflict has not resulted in a direct material adverse impact on our business to date, 
the implications of the Russia and Ukraine conflict in the short-term and long-term are difficult to predict at this time. Factors 
such as increased energy costs, the availability of certain raw materials for aircraft manufacturers, embargoes on flights from 
Russian airlines, sanctions on Russian companies, and the stability of Ukrainian customers could impact the global economy 
and aviation sector. 
In October 2024, a customer reported within the Aerospace segment declared bankruptcy. As a result, the Company recorded a 
full reserve of $1.0 million for outstanding receivables, a reserve of $1.7 million for inventory and $0.6 million for impairment 
of fixed assets. In November 2023, a non-core contract manufacturing customer reported within the Aerospace segment filed 
for bankruptcy under Chapter 11. As a result, the Company recorded a full reserve of $7.5 million for outstanding accounts 
receivable and a reserve of $3.6 million for inventory. The associated assets existed prior to 2023.
DIVESTITURES
On February 13, 2019, the Company completed a divestiture of its semiconductor test business within the Test Systems 
segment. The total proceeds of the divestiture included two elements of contingent purchase consideration (“earnout”). In 
March 2022, the Company agreed with the earnout calculation for the calendar 2021 earnout in the amount of $11.3 million. 
The Company recorded the gain and received the payment in the first quarter of 2022. In March 2023, the Company agreed 
with the final earnout calculation for the calendar 2022 earnout in the amount of $3.4 million. The Company recorded the gain 
26

and received the payment in the first quarter of 2023. We are not eligible for any further earnout payments related to this 
divestiture.
MARKETS
Commercial Transport Market
The commercial transport market is our largest end market with sales driven by new aircraft production and aftermarket airline 
retrofit programs. In the commercial transport market, while many of our key long-term fundamentals remain intact, we 
continue to see residual, though improving, near-term market pressure due to effects of certain supply chain challenges. We 
have experienced improvement throughout 2024 driven by improved activity with our airline customers, though production was 
negatively affected by the quality control issues and labor workforce stoppage on the 737 MAX. Aircraft build rates are 
expected to continue to improve during 2025 and 2026 from current levels as production of both the 737 MAX and A-320 are 
expected to increase, and the aftermarket is expected to strengthen over the course of the year as aircraft utilization and load 
factors increase. International travel utilizing primarily widebody aircraft is close to pre-pandemic levels and we believe 
widebody aircraft production rates will continue to directionally match air traffic volumes.
Sales to the commercial transport market include sales of lighting and safety systems, electrical power and seat motion systems, 
aircraft structures, avionics products and systems certification. Sales to this market totaled approximately $524.6 million or 
65.9% of our consolidated sales in 2024. 
Maintaining and growing sales to the commercial transport market will depend not only on continued market recovery post-
pandemic, but also on airlines’ capital spending budgets for cabin upgrades as well as the purchase of new aircraft by global 
airlines. This spending by the airlines is impacted by their profits, cash flow and available financing as well as competitive 
pressures between the airlines to improve the travel experience for their passengers. We expect that new aircraft will be 
equipped with more passenger and aircraft connectivity and in-seat power than previous generation aircraft which drives 
demand for our avionics and power products. This market has historically experienced strong growth from airlines installing in-
seat passenger power systems on their existing and newly delivered aircraft. Our ability to maintain and grow sales to this 
market depends on our ability to maintain our technological advantages over our competitors and maintain our relationships 
with major in-flight entertainment suppliers and global airlines.
Military Aerospace Market
Sales to the military aerospace market include sales of lighting and safety products, avionics products, electrical power products 
and structures products. Sales to this market totaled approximately 11.1% of our consolidated sales and amounted to $88.0 
million in 2024.
The military market is dependent on governmental funding which can change from year to year. Risks are that overall spending 
may be reduced in the future, specific programs may be eliminated or that we fail to win new business through the competitive 
bid process. Astronics does not have significant reliance on any one program such that cancellation of a particular program will 
cause material financial loss. We believe that we will continue to have opportunities similar to past years with respect to this 
market.
General Aviation Market
Sales to the general aviation market consist mostly of line-fit products driven by aircraft build rates although there are some 
aftermarket sales as well. Sales to the general aviation market include sales of lighting and safety products, avionics products, 
and electrical power and seat motion products. Sales to this market totaled approximately 9.3% of our consolidated sales in 
2024 and amounted to $74.3 million. 
Sales to the general aviation market are driven by our ship set content on new aircraft and build rates of new aircraft. General 
aviation OEM build rates are impacted by global wealth creation and corporate profitability. We continue to see opportunities 
on new aircraft currently in the design phase to employ our lighting and safety, electrical power and avionics technologies in 
this market. There is risk involved in the development of products for any new aircraft including the risk that the aircraft will 
not ultimately be produced or that it will be produced in lower quantities than originally expected and thus impacting our return 
on our engineering and development efforts.
Test Systems Products
Sales by our Test Systems segment accounted for approximately 11.2% of our consolidated sales in 2024 and amounted to 
$88.7 million. This segment designs, develops, manufactures and maintains automated test systems that support the aerospace 
and defense, communications and mass transit industries as well as training and simulation devices for both commercial and 
27

military applications. Sales to the aerospace and defense market were $45.4 million in 2024. Sales to the mass transit market 
were $10.9 million and sales to the radio test market were $32.5 million in 2024.
Sales to the military and mass transit markets are subject to fluctuations resulting from changes in governmental spending, 
elimination of certain programs, or failure to win new business through the competitive bid process. Consistent with the 
Aerospace segment, the Test Systems segment does not significantly rely on any one program such that cancellation of a 
particular program will cause material financial loss, and we believe that we will continue to have opportunities similar to past 
years regarding this market.
CRITICAL ACCOUNTING ESTIMATES
Our financial statements and accompanying notes are prepared in accordance with U.S. generally accepted accounting 
principles. The preparation of the Company’s financial statements requires management to make estimates, assumptions and 
judgments that affect the amounts reported. These estimates, assumptions and judgments are affected by management’s 
application of accounting policies, which are discussed in Note 1, Summary of Significant Accounting Principles and Practices, 
to the Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data, of this report. The critical 
accounting policies have been reviewed with the Audit Committee of our Board of Directors.
Revenue Recognition
Astronics recognizes revenue when it transfers control of a promised good or service to a customer in an amount that reflects 
the consideration it expects to receive in exchange for the good or service. Our performance obligations are satisfied and control 
is transferred either at a point-in-time or over-time. The majority of our revenue is recognized at a point-in-time when control is 
transferred, which is generally evidenced by the shipment or delivery of the product to the customer, a transfer of title, a 
transfer of the significant risks and rewards of ownership, and customer acceptance. For certain contracts under which we 
produce products with no alternative use and for which we have an enforceable right to recover costs incurred plus a reasonable 
profit margin for work completed to date and for certain other contracts under which we create or enhance a customer-owned 
asset while performing repair and overhaul services, control is transferred to the customer over time. The Company recognizes 
revenue using an over time recognition model for these types of contracts.
We utilize the cost-to-cost method as a measure of progress for performance obligations that are satisfied over time as we 
believe this input method best represents the transfer of control to the customer. Under the cost-to-cost method, the extent of 
progress toward completion is measured based on the proportion of costs incurred to date to the total estimated costs at 
completion of the performance obligation. These projections require management to make numerous assumptions and estimates 
relating to items such as the complexity of design and related development costs, performance of subcontractors, availability 
and cost of materials, labor productivity and cost, overhead, capital costs, and manufacturing efficiency. We review our cost 
estimates on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates 
are largely based on negotiated or estimated purchase contract terms, historical performance trends and other economic 
projections.
See Note 2, Revenue, to the Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data, of this 
report for a further description of revenue recognition under ASC 606. 
Reviews for Impairment of Goodwill
Our goodwill is the result of the excess of purchase price over net assets acquired from acquisitions. We had approximately 
$58.1 million and $58.2 million of goodwill as of December 31, 2024 and 2023, respectively.
We identify our reporting units by assessing whether the components of our operating segments constitute businesses for which 
discrete financial information is available and segment management regularly reviews the operating results of those 
components. The Test Systems operating segment is its own reporting unit while the other reporting units are one level below 
our Aerospace operating segment.
The Company tests goodwill at the reporting unit level on an annual basis or more frequently if an event occurs or 
circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. 
We use the discounted cash flow method to estimate the fair value of each of our reporting units. The discounted cash flow 
method incorporates various assumptions, the most significant being projected sales growth rates, operating profit margins and 
cash flows, the terminal growth rate and the discount rate. Management projects sales growth rates, operating margins and cash 
flows based on each reporting unit’s current business, expected developments and operational strategies. If the carrying value of 
28

the reporting unit exceeds its fair value, goodwill is considered impaired and the impairment loss is recorded for the amount by 
which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying value of goodwill.
The Company’s four reporting units remaining with goodwill as of the first day of our fourth quarter were subject to the annual 
goodwill impairment test. Based on our quantitative assessments of our reporting units, we concluded that goodwill was not 
impaired in 2024, 2023 or 2022.

CONSOLIDATED OVERVIEW OF OPERATIONS
2024 Compared With 2023 
Growth in sales were driven by the Aerospace segment due to continued strength in demand primarily from the Commercial 
Transport market. Aerospace sales were up $101.9 million, or 16.8%, while Test Systems sales increased $4.4 million on higher 
radio test revenue. The prior-year period Test Systems sales benefited from the reversal of a $5.8 million deferred revenue 
liability recorded with a previous acquisition.
Consolidated cost of products sold in 2024 was $627.1 million, compared with $568.4 million in the prior year. The increase 
was primarily due to higher volume, coupled with an increase of $11.0 million for resumed incentive programs including 
bonuses, 401K profit sharing contributions, a $5.2 million warranty reserve related to a new product launch that requires field 
modification, and a $6.1 million increase in non-bankruptcy related inventory reserves, offset by a decrease in reserves 
associated with customer bankruptcies previously discussed of $1.9 million.
Selling, General and Administrative (“SG&A”) expenses were $141.9 million in 2024 compared with $127.5 million in the 
prior-year period primarily due to increased wages and benefits, including a $6.0 million increase for resumed incentive 
programs, and an increase of $8.9 million in litigation-related legal expenses and reserve adjustments in 2024. SG&A was also 
impacted by a $1.9 million increase in restructuring-related severance charges incurred in our Test Systems segment. The prior 
year was negatively impacted by a $7.5 million reserve for accounts receivable compared to a $1.5 million reserve for accounts 
receivable and fixed asset impairments in the current year associated with customer bankruptcies previously discussed.
On February 21, 2025, the UK High Court of Justice rendered a decision in the Company’s long-running patent infringement 
dispute in that jurisdiction. The ruling requires payment of approximately $11.9 million and, as a result, SG&A expense in 2024 
reflects a $4.8 million true up to legal reserves for that matter. Any additional amounts required to be paid by the Company 
related to certain other factors peripheral to the damages award will be determined at follow-up hearings expected to occur in 
the first half of 2025. The Company expects that payment of the final liability will be required in the second quarter of 2025, 
and that an appeal, if any, would likely be heard in early 2026.
29

Impacting net income was $10.1 million for the loss on extinguishment of debt which included $4.5 million in call premiums on 
the previous term loans and the write-off of $5.6 million of associated deferred financing costs.
In 2023, the Company recognized a final earnout of $3.4 million for the 2019 sale of its semiconductor test business. Other 
Income in 2023 included $1.8 million associated with the reversal of a liability related to an equity investment.
Interest expense decreased to $22.0 million from $23.3 million in the year ended December 31, 2023 related to the lower 
average borrowings and cost of debt resulting from the Company’s refinancing activities.
Tax expense of $8.3 million was primarily due to a valuation allowance applied against the deferred tax asset associated with 
research and development costs that are required to be capitalized for tax purposes, compared with a tax expense of $0.1 million 
in the prior year. 
Consolidated net loss was $16.2 million, or $0.46 per diluted share, compared with net loss of $26.4 million, or $0.80 per 
diluted share, in the prior year. 
For the year, bookings totaled $808.1 million, resulting in a book-to-bill ratio of 1.02:1. Backlog at the end of the year was 
$599.2 million
Income Taxes
Our effective tax rates for 2024 and 2023 were (106.1)% and (0.4)%, respectively. Prior to 2022, research and development 
costs were deducted as incurred. However, beginning with the 2022 tax year, these costs are required to be capitalized for tax 
purposes and amortized over five years. While this would typically result in the creation of an associated deferred tax asset, due 
to our cumulative three-year pre-tax loss, a valuation allowance was applied against the deferred tax asset. In addition to state 
income taxes, the following items had the most significant impact on the difference between our statutory U.S. federal income 
tax rate (21% in 2024 and 2023) and our effective tax rate:
2024:
•
Recognition of approximately $13.6 million of valuation allowance against federal deferred tax assets. See Note 11, 
Income Taxes, to the Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data, of 
this report for additional information.
•
Recognition of approximately $3.4 million of 2024 U.S. R&D tax credits.
2023:
•
Recognition of approximately $6.8 million of valuation allowance against federal deferred tax assets. See Note 11, 
Income Taxes, to the Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data, of 
this report for additional information.
•
Recognition of approximately $3.4 million of 2023 U.S. R&D tax credits.
2023 Compared With 2022
For a comparison of our results of operations for the years ended December 31, 2023 and 2022, see Item 7, Management’s

2024 Compared With 2023
Aerospace segment sales of $706.7 million were up $101.9 million, or 16.8%. The improvement was driven by a 21.4%, or 
$92.4 million, increase in Commercial Transport sales. Growth was primarily related to increased demand by airlines for cabin 
power, lighting and safety and inflight entertainment & connectivity (“IFEC”) products which are in the Electrical Power & 
Motion, Lighting & Safety and Avionics product groups. 
Military Aircraft sales increased $26.4 million, or 42.8%, to $88.0 million, driven by increased demand for Lighting & Safety 
and Avionics products as well as progress on the FLRAA program. General Aviation sales decreased $6.5 million, or 8.0%, to 
$74.3 million, primarily due to lower sales of antenna products. Other sales decreased $10.4 million as the Company is winding 
down its non-core contract manufacturing arrangements.
Aerospace segment operating profit of $62.4 million, or 8.8%, improved over the prior year despite a $16.4 million increase in 
litigation-related legal expenses and reserve adjustments related to the ongoing patent dispute previously discussed, $5.2 
million in warranty expense related the previously-mentioned field modification, a $6.7 million increase in non-bankruptcy 
related inventory reserves and a $13.2 million increase in compensation expense related to the resumption of the Company’s 
incentive programs, offset by a decrease in non-cash reserves associated with customer bankruptcies of $7.8 million. The 
improvement in segment operating profit reflects leverage gained on higher volume and improving production efficiencies.
Aerospace bookings in 2024 were $732.7 million, for a book-to-bill ratio of 1.04:1. The book-to-bill ratio is calculated as total 
orders received during the period compared with total revenue recognized during the period. The Aerospace segment’s backlog 
at December 31, 2024 was $537.6 million, compared to $511.5 million at December 31, 2023.

2024 Compared With 2023
Test Systems segment sales were $88.7 million, up $4.4 million driven primarily by our U.S. Army and U.S. Marine Corps’ 
Radio Test programs. However, sales were negatively impacted by $3.5 million due to a revision of estimated costs to complete 
certain long-term mass transit Test contracts. The revision resulted in reduced revenue recognized in the period due to lower 
estimates of the percentage of work completed on the programs. The prior-year period sales benefited from the reversal of a 
$5.8 million deferred revenue liability recorded with a previous acquisition.
Test Systems operating loss was $8.5 million compared with operating loss of $8.7 million in 2023. Test Systems operating loss 
for the prior-year period benefited from the $5.8 million sales adjustment resulting from the reversal of the deferred revenue 
liability. The 2024 results benefited from the margin realized on the HHRTS and TS-4549/T sales and a $7.5 million decrease 
in litigation-related expenses, however Test Systems’ operating performance continues to be negatively affected by mix and 
under absorption of fixed costs due to low volume, the resumption of the Company’s incentive programs, and the revision of 
estimated costs on certain long-term mass transit contracts discussed above, which resulted in a $3.5 million reversal of 
revenue. Additional restructuring initiatives were implemented in the 2024 fourth quarter, which are expected to provide 
annualized savings of approximately $4 million to $5 million, beginning in the first quarter of 2025. Restructuring-related 
severance expense increased $1.6 million in 2024 compared with 2023. During the fourth quarter of 2024, we also substantially 
completed the closure of a third Test facility in the last two years. 
Bookings for the Test Systems segment in 2024 were $75.4 million, for a book-to-bill ratio of 0.85:1 for the year. Backlog in 
the Test Systems segment was $61.7 million at December 31, 2024, compared to $75.0 million at December 31, 2023. 
2023 Compared With 2022
For a comparison of Test Systems segment results for the years ended December 31, 2023 and 2022, see Item 7, Management’s 
Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the year 
ended December 31, 2023 filed with the SEC on March 5, 2024.
CONTRACTUAL OBLIGATIONS AND OTHER COMMITMENTS
For further information on our contractual obligations and other commitments as of December 31, 2024 and estimated timing 
thereof, see the notes to the Consolidated Financial Statements referenced below, in Item 8, Financial Statements and 
Supplementary Data, of this report.
Long-term Debt and Interest Payments — Refer to Note 8, Long-Term Debt, in Item 8, Financial Statements and 
Supplementary Data, of this report. On November 25, 2024, the Company entered into a second amendment to the ABL 
Revolving Credit Facility that increased the maximum aggregate amount available to be borrowed thereunder to $220.0 million 
from $200.0 million. The ABL Revolving Credit Facility has a scheduled maturity of July 11, 2027, an interest rate of SOFR 
plus 2.75% to 3.25% and is collateralized primarily by inventory, accounts receivable, machinery and equipment and real 
estate. The ABL Revolving Credit Facility requires payment of a quarterly commitment fee of 0.25% or 0.375% based on the 
Company’s average excess availability. 
32

On December 3, 2024, the Company issued $165.0 million aggregate principal amount of Convertible Notes due 2030, which 
amount includes the additional notes issued pursuant to the initial purchasers’ full exercise of their option to purchase additional 
Convertible Notes. The Convertible Notes bear interest at a rate of 5.500% per annum, payable semi-annually in arrears on 
March 15 and September 15 of each year, beginning on March 15, 2025. The Convertible Notes will mature on March 15, 
2030, unless earlier converted, redeemed or repurchased. The initial conversion rate is 43.6814 shares of common stock per 
$1,000 principal amount of Convertible Notes, which represent the initial conversion price of $22.89 per share.
Future interest payments under the ABL Revolving Credit Facilities and the Convertible Notes of approximately $49.9 million 
have been estimated using the applicable interest rate of each debt instrument based on expected future borrowings or 
outstanding amount of Convertible Notes, as applicable. Actual future ABL borrowings and rates may differ from those used to 
estimate the amounts discussed above. 
Purchase Obligations — Purchase obligations are comprised of the Company’s commitments for goods and services in the 
normal course of business and amount to approximately $184.0 million payable over the next twelve months.
Supplemental Retirement Plan and Post Retirement Obligations — Anticipated payments related with the Company’s defined 
benefit plans are detailed in Note 13, Retirement Plans and Related Post Retirement Benefits, in Item 8, Financial Statements 
and Supplementary Data, of this report.
Lease Obligations — Refer to Note 10, Leases, in Item 8, Financial Statements and Supplementary Data, of this report for 
details on obligations and timing of expected future lease payments, including a five-year maturity schedule. The lease maturity 
schedule excludes legally binding operating lease payments of $3.3 million per year through 2033 for a lease that has been 
signed in 2025, but not commenced.
Legal Reserves — Refer to Note 19, Legal Proceedings, in Item 8, Financial Statements and Supplementary Data, of this report 
for management’s estimate of damages to be paid related to our ongoing litigation with Lufthansa Technik and timing thereof.

1 Working capital is calculated as the difference between Current Assets and Current Liabilities.
Our cash flow from operations and available borrowing capacity under our ABL Revolving Credit Facilities are expected to 
provide us with the financial resources needed to run our operations and reinvest in our business for at least the next 12 months.
Our ability to maintain sufficient liquidity is highly dependent upon achieving expected operating results. Failure to achieve 
expected operating results could have a material adverse effect on our liquidity, our ability to obtain financing or access our 
existing financing, and our operations in the future.
Operating Activities
Cash provided by operating activities totaled $30.6 million in 2024, as compared with $24.0 million cash used for operating 
activities in 2023. Cash flow from operating activities improved compared with 2023 primarily related to improvement in our 
financial results, coupled with accounts receivable using less cash, partially offset by increased outflows related to inventory 
and accounts payable. Non-cash items include $10.1 million for the loss on extinguishment of debt in 2024 and a $5.8 million 
deferred liability recovery in 2023. The $3.4 million earnout in 2023 from the sale of the semiconductor business is treated as 
investing activities and thus is shown as a non-cash gain removed from the calculation of cash flow from operations. 
33

Our cash flows from operations are primarily dependent on our net loss adjusted for non-cash expenses and income and the 
timing of collections of receivables, inventory levels and payments to suppliers and employees. Sales and operating results of 
our Aerospace segment are influenced by build rates of new aircraft, which are subject to general economic conditions, airline 
passenger travel and spending for government and military programs. Our Test Systems segment sales depends in part on 
capital expenditures of the aerospace and defense industry which, in turn, depend on current and future demand for those 
products. A reduction in demand for our customers’ products would adversely affect our operating results and cash flows.
Investing Activities
Cash used for investing activities in 2024 was $8.4 million compared to $4.1 million cash used for investing activities in 2023. 
Investing cash flows in 2023 were positively impacted by the receipt of $3.4 million related to the calendar 2022 earnout from 
the sales of the semiconductor business.
Future requirements for PP&E depend on numerous factors, including expansion of existing product lines and introduction of 
new products. Management believes that our cash flow from operations and available capacity under our ABL Revolving Credit 
Facility will provide for these capital expenditures. We expect to continue to evaluate acquisition opportunities in the future.
Financing Activities
Cash used for financing activities totaled $14.5 million for 2024, as compared with cash provided by financing activities of 
$25.4 million for 2023. The Company received proceeds from our at-the-market equity offering program (the “ATM Program”) 
of $21.3 million in 2023. Additionally, the Company made net borrowings under our credit facilities of $2.5 million in 2024 
compared with net borrowings of $8.5 million in 2023, coupled with a $9.9 million increase in costs associated with amending 
and refinancing our credit facilities in 2024. 
The Company amended its ABL Revolving Credit Facility on July 11, 2024, by entering into the Seventh Amended and 
Restated Credit Agreement, which set the maximum aggregate amount that the Company can borrow pursuant to the revolving 
credit line at $200.0 million, with borrowings subject to a borrowing base determined primarily by inventory, accounts 
receivable, machinery and equipment and real estate. The Company also entered into a $55.0 million Term Loan Facility on 
July 11, 2024. The Company repaid in full all outstanding indebtedness under the previous term loan dated January 19, 2023. 
The payoff amount of approximately $84.5 million consisted of a repayment of the principal amount of approximately $80.3 
million, plus accrued but unpaid interest, fees and expenses, including a call premium of 4.00% which satisfied all of the 
Company’s indebtedness obligations thereunder. The Company funded the repayment of its obligations under the previous 
agreement with borrowings under the ABL Revolving Credit Facility and the Term Loan Facility.
On November 25, 2024, the Company entered into a second amendment to the ABL Revolving Credit Facility which increased 
the maximum aggregate amount that the Company can borrow pursuant to the ABL Revolving Credit Facility to $220.0 million 
from $200.0 million. The maturity date of borrowings under the ABL Revolving Credit Facility remains July 11, 2027. The 
Company and the applicable lenders also agreed in a separate first amendment to increase the amount of unsecured 
indebtedness the Company is permitted to incur under the ABL Revolving Credit Facility, subject to completion of the 
Convertible Notes offering (discussed below).
Under the terms of the ABL Revolving Credit Facility, the Company pays interest on the unpaid principal amount of the ABL 
Revolving Credit Facility at a rate equal to SOFR plus a term SOFR adjustment in the amount of 0.10% per annum (which 
collectively shall be at least 1.00%) plus an applicable margin ranging from 2.75% to 3.25% determined based upon the 
Company’s Excess Availability (as defined in the ABL Revolving Credit Facility). The Company is required to pay a quarterly 
commitment fee under the ABL Revolving Credit Facility on undrawn revolving credit commitments in an amount equal to 
0.25% or 0.375% based on the Company’s average excess availability under the ABL Revolving Credit Facility. On December 
31, 2024, there was $10.0 million outstanding on the ABL Revolving Credit Facility and there remained $209.7 million 
available for future borrowings, net of outstanding letters of credit, before our minimum excess availability requirement 
discussed below.
Pursuant to the ABL Revolving Credit Facility, the Company is subject to a minimum fixed charge coverage ratio of 1.10 to 
1.00. The Company is also required to maintain minimum excess availability of the greater of 10% of the borrowing base under 
the ABL Revolving Credit Facility, or $15.0 million. As of December 31, 2024, the Company was in compliance with these 
covenants.
On December 3, 2024, the Company issued $165.0 million aggregate principal amount of Convertible Notes, which amount 
includes the additional Convertible Notes issued pursuant to the initial purchasers’ full exercise of their option to purchase 
additional Convertible Notes. The Convertible Notes bear interest at a rate of 5.500% per annum, payable semi-annually in 
arrears on March 15 and September 15 of each year, beginning on March 15, 2025. The Convertible Notes will mature on 
34

March 15, 2030, unless earlier converted, redeemed or repurchased. The initial conversion rate is 43.6814 shares of common 
stock per $1,000 principal amount of Convertible Notes, which represent the initial conversion price of $22.89 per share. The 
Convertible Notes are convertible at the option of the holders at any time on or after December 15, 2029, until the close of 
business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, the Company will 
satisfy its conversion obligations by paying and/or delivering, as the case may be, cash, shares of its common stock or a 
combination of cash and shares of its common stock, at its election. Beginning March 20, 2028, if the Company’s stock price 
has been at least 130% of the conversion price for a specified period of time, the Convertible Notes may be called at the option 
of the issuer. Under the same conditions, the Company can elect to redeem the Convertible Notes for cash. After the first 
quarter of 2025, if the Company’s stock price has been at least 130% of the conversion price for 20 of 30 trading days ending 
on and including the last trading day of the immediately preceding quarter, the Convertible Notes may be called at the option of 
the holder. The fair value of the Convertible Notes was approximately $176.9 million as of December 31, 2024 based on quoted 
prices for these instruments in active markets, and is classified as a Level 1 measurement within the fair value hierarchy.
On December 3, 2024, the Company repaid in full all outstanding indebtedness under the Term Loan Facility. The Term Loan 
Facility payoff consisted of a repayment of a principal amount of approximately $54.9 million, plus accrued but unpaid interest, 
fees and expenses, including a call premium of 3.00% which satisfied all of the Company’s indebtedness obligations 
thereunder. The Company funded the repayment of its obligations under the Term Loan Facility with a portion of the proceeds 
received from the issuance and sale of the Convertible Notes. Scheduled principal payments of $9.0 million were payable under 
the Term Loan Facility and were classified as current in the accompanying Consolidated Balance Sheets as of December 31, 
2023. The interest rate on current maturities of long-term debt was 14.20% at December 31, 2023.
The Company incurred $12.2 million in incremental debt issuance costs during 2024. All costs are amortized to interest expense 
over the term of the respective agreement. Debt issuance cost amortization expense was approximately $2.6 million, 
$3.0 million and $0.8 million in 2024, 2023 and 2022, respectively. Unamortized deferred debt issuance costs associated with 
the ABL Revolving Credit Facility ($3.0 million as of December 31, 2024) are recorded within Other Assets and those 
associated with the Convertible Notes ($6.3 million as of December 31, 2024) are recorded as a reduction of the carrying value 
of the debt on the Consolidated Balance Sheets. The unamortized balance of deferred debt issuance costs on our previous credit 
facilities of $2.0 million was recorded within Other Assets and $4.3 million was recorded as a reduction of the carrying value of 
the debt on the Consolidated Balance Sheets at December 31, 2023.
In 2024, the Company recorded a loss on extinguishment of the debt of approximately $10.1 million below Income from 
Operations, which was comprised of $4.5 million of prepayment fees on the previous term loans and a write-off of $5.6 million 
of unamortized deferred financing costs. The Company also had a write-off of deferred financing costs of approximately 
$0.5 million related to the exiting ABL lender in Interest Expense within the Consolidated Statements of Operations.
Certain of the Company’s subsidiaries are borrowers under the ABL Revolving Credit Facility and the assets of such 
subsidiaries also secure the obligations under the ABL Revolving Credit Facility. In the event of voluntary or involuntary 
bankruptcy of the Company or any subsidiary, all unpaid principal and other amounts owing under the credit facilities 
automatically become due and payable. Other events of default, such as failure to make payments as they become due and 
breach of financial and other covenants, change of control, cross default under other material debt agreements, and a going 
concern qualification for any reason other than loan maturity date give the agent the option to declare all such amounts 
immediately due and payable.
On June 5, 2023, the Company filed a shelf registration statement on Form S-3 with the SEC, which allows us to issue shares of 
common stock, preferred stock, warrants, subscription rights, purchase contracts and debt securities in one or more offerings up 
to an aggregate offering price of $150 million and on terms to be determined at the time of the offering. On August 8, 2023, the 
Company initiated an at-the-market equity offering program for the sale from time to time of shares of the Company’s common 
stock, par value $0.01 per share having an aggregate offering price of up to $30 million.
During the year ended December 31, 2024, the Company did not sell any shares of our common stock under the ATM Program. 
During the year ended December 31, 2023, the Company sold 1,334,228 shares of our common stock under the ATM Program. 
The Company generated $21.8 million in aggregate gross proceeds from sales under the ATM Program at an average sale price 
of $16.31 per share. Aggregate net proceeds from the ATM Program were $21.3 million after deducting related expenses, 
including commissions to the sales agents and issuance costs. As of December 31, 2024, the Company had remaining capacity 
under the ATM Program to sell shares of common stock having an aggregate offering price up to approximately $8.2 million.
On February 4, 2025, the Company entered into a factoring agreement with Citibank, N.A. under which we can sell certain 
receivables resulting from sales to a certain customer. The arrangement is designed to provide the Company with an immediate 
cash advance on eligible receivables, up to a limit of $45 million a year as restricted by our ABL Revolving Credit Facility. As 
of the date of this report, the Company has not utilized the factoring agreement. Management continues to evaluate its financing 
35

needs and the potential utilization of the factoring agreement based on the Company’s operational and working capital 
requirements. There is no current commitment or obligation to factor any receivables under this agreement.
Cash on hand at the end of the year was $18.4 million. Net debt was $156.6 million, compared with $161.2 million at the end of 
2023.
Lufthansa Technik AG (“Lufthansa”) filed actions in Germany, the United Kingdom (“UK”) and France. These matters are 
more fully discussed in Note 19, Legal Proceedings, to our Consolidated Financial Statements in Item 8, Financial Statements 
and Supplementary Data and Item 1A, Risk Factors, of this report.
The Company expects its cash flow from operations will provide sufficient cash flows to fund operations, including payment of 
the $11.9 million damage award related to the February 21, 2025 ruling issued in relation to the Lufthansa UK matter. 
However, the Company may also evaluate various actions and alternatives to enhance its profitability and cash generation from 
operating activities, which could include manufacturing efficiency initiatives, cost-reduction measures, working with vendors 
and suppliers to reduce lead times and expedite shipment of critical components, and working with customers to expedite 
receivable collections. The Company may also utilize available capacity under the ABL Revolving Credit Facility.
Our ability to maintain sufficient liquidity and comply with financial debt covenants is highly dependent upon achieving 
expected operating results. Failure to achieve expected operating results could have a material adverse effect on our liquidity, 
our ability to obtain financing or access our existing financing, and our operations in the future and could allow our debt holders 
to demand payment of all outstanding amounts.
DIVIDENDS
Management believes that it should retain the capital generated from operating activities for investment in advancing 
technologies, acquisitions and debt retirement. Accordingly, there are no plans to institute a cash dividend program.

See Note 1, Summary of Significant Accounting Principles and Practices, of the Consolidated Financial Statements in Item 8, 
Financial Statements and Supplementary Data, of this report.
ITEM 7A. 
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The Company has limited exposure to fluctuation in foreign currency exchange rates to U.S. dollar, primarily in Canadian 
dollars and Euros currency. Approximately 90% of the Company’s consolidated sales are transacted in U.S. dollars. Net assets 
held in or measured in Canadian dollars amounted to $14.0 million at December 31, 2024. A 10% change in the value of the 
U.S. dollar versus the Canadian dollar would have had an immaterial impact to 2024 net loss. Net assets held in or measured in 
Euros amounted to $26.1 million at December 31, 2024. A 10% change in the value of the U.S. dollar versus the Euros would 
have had an immaterial impact to 2024 net loss.
Risk due to fluctuation in interest rates is a function of the Company’s floating rate debt obligations, which total approximately 
$10.0 million as of December 31, 2024. A change of 1% in interest rates of all variable rate debt would impact annual net loss 
by approximately $0.1 million, before income taxes.
As disclosed elsewhere in this report, the future impacts of the Russia and Ukraine conflict and the COVID-19 pandemic and 
their residual effects, including economic uncertainty, inflationary environment and disruption within the global supply chain, 
labor markets and aerospace industry, on our business remain uncertain. As we cannot anticipate the ultimate duration or scope 
of the Russia-Ukraine war and the residual effects of the COVID-19 pandemic, the ultimate financial impact to our results 
cannot be reasonably estimated, but could be material.

ITEM 8.
FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
Report of Independent Registered Public Accounting Firm
To the Shareholders and the Board of Directors of Astronics Corporation
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Astronics Corporation (the Company) as of December 31, 
2024 and 2023, the related consolidated statements of operations, comprehensive loss, shareholders’ equity and cash flows for 
each of the three years in the period ended December 31, 2024, and the related notes and financial statement schedule listed in 
the Index at Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated 
financial statements present fairly, in all material respects, the financial position of the Company at 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 U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in 
Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(2013 framework), and our report dated March 5, 2025 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to 
error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the financial statements that 
were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that 
are material to the financial statements and (2) 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 matters below, providing separate opinions on the critical audit 
matters or on the accounts or disclosures to which they relate.
Valuation of Goodwill of the Test Systems Reporting Unit
Description 
of the 
Matter
As of December 31, 2024, the Company’s goodwill balance was $58.1 million, of which $21.6 million related to 
the Test Systems reporting unit. As discussed in Notes 1 and 7 of the consolidated financial statements, the 
Company tests goodwill for impairment at the reporting unit level on an annual basis or more frequently if an 
event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit 
below its carrying amount. For each reporting unit, the Company performed a quantitative test using the 
discounted cash flow method to estimate fair value. The discounted cash flow method incorporates various 
assumptions, the most significant being projected sales growth rates, operating margins and cash flows, EBITDA 
margins, the terminal growth rate, and the weighted average cost of capital. If the carrying value of the reporting 
unit exceeds its fair value, goodwill impairment is measured as the amount by which the reporting unit’s 
carrying value exceeds its fair value, not to exceed the carrying value of goodwill. 
Auditing management’s assumptions was challenging due to the estimation required in determining the fair 
value of the Company’s Test Systems reporting unit with goodwill. The fair value estimate for the Test Systems 
reporting unit was sensitive to the significant assumptions of the projected sales growth rates and EBITDA 
margins. These assumptions are affected by expectations about future market and economic conditions.
37

How We 
Addressed 
the Matter 
in Our 
Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the 
Company’s goodwill impairment testing process. This included the determination of the underlying significant 
assumptions described above, and the completeness and accuracy of the data used in the impairment analysis. 
To test the estimated fair value of the Company’s Test Systems reporting unit, we performed audit procedures 
with the assistance of our valuation professionals that included, among others, assessing the methodology used, 
testing the significant assumptions discussed above and testing the underlying data used in the impairment 
analysis. We compared the significant assumptions used by management to current industry and economic 
trends, historical trends of the Company, and other relevant factors. We assessed the historical accuracy of 
management’s estimates and performed sensitivity analyses of significant assumptions to evaluate the changes in 
the fair value of the reporting unit that would result from changes in the assumptions. In addition, we tested the 
reconciliation of the fair value of the Company’s reporting units to the market capitalization of the Company as 
of the annual impairment testing date. 
Revenue Recognition
Description 
of the 
Matter
For the year ended December 31, 2024, the Company’s sales totaled $795.4 million. As discussed in Note 2 to 
the consolidated financial statements, the majority of the Company’s revenue from contracts with customers is 
recognized at a point in time when the customer obtains control of the product, which is generally upon delivery 
to the customer. For contracts with customers in which the Company satisfies its promise to the customer to 
provide a service or a product that has no alternative use to the Company and the Company has enforceable 
rights to payment for progress completed to date inclusive of profit, the Company recognizes revenue over time 
as it satisfies the performance obligation. 
Auditing management’s evaluation of contracts with customers was especially challenging due to the judgment 
required to analyze the terms and conditions of the Company’s various customer contracts given that such terms 
and conditions are nonstandard. This included the assessment of alternative use and enforceable right to payment 
for purposes of determining if revenue from the contract should be recognized over time or at a point in time.
How We 
Addressed 
the Matter 
in Our 
Audit
We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the 
Company’s revenue recognition process. We tested controls over management’s review of the terms and 
conditions of contracts with customers which included an analysis of the determination of alternative use and a 
review of the conclusion as to whether revenue from such performance obligations should be recognized over 
time or at a point in time. 
We performed procedures to test revenue recognition which included, among others, reading a sample of 
executed contracts and purchase orders to understand the contract and performing an independent assessment of 
alternative use and enforceable rights to payment. We tested the completeness and accuracy of the Company’s 
contract summary documentation, specifically related to determination of alternative use consideration and 
enforceable rights to payment plus profit which determines the timing of revenue recognition.

Management’s Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term 
is defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act. Under the supervision and with the participation of our 
management, including the Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the 
effectiveness of our internal control over financial reporting as of December 31, 2024 based upon the framework in Internal 
Control – Integrated Framework originally issued in 2013 by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO). Based on that evaluation, our management concluded that our internal control over financial reporting is 
effective as of December 31, 2024.
Ernst & Young LLP, independent registered public accounting firm, has audited our Consolidated Financial Statements 
included in this Annual Report on Form 10-K and, as part of their audit, has issued their report, included herein, on the 
effectiveness of our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
To the Shareholders and the Board of Directors of Astronics Corporation
Opinion on Internal Control Over Financial Reporting
We have audited Astronics Corporation’s internal control over financial reporting as of December 31, 2024, based on criteria 
established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (2013 framework) (the COSO criteria). In our opinion, Astronics Corporation (the Company) maintained, in all 
material respects, effective internal control over financial reporting as of December 31, 2024, based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related consolidated 
statements of operations, comprehensive loss, shareholders’ equity and cash flows for each of the three years in the period 
ended December 31, 2024, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) and our 
report dated March 5, 2025 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report 
on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control 
over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all 
material respects. 
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 
performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a 
reasonable basis for our opinion.
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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) 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 (3) 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES AND PRACTICES
Description of the Business
Astronics Corporation (“Astronics” or the “Company”) is a leading provider of advanced technologies to the global aerospace, 
defense, and electronics industries. Our products and services include advanced, high-performance electrical power generation, 
distribution and seat motion systems, lighting and safety systems, avionics products, systems and certification, aircraft 
structures and automated test systems.
We have principal operations in the United States (“U.S.”), Canada and France, as well as engineering offices in Ukraine and 
India.
The Company has two reportable segments, Aerospace and Test Systems. The Aerospace segment designs and manufactures 
products for the global aerospace and defense industry. Our Test Systems segment designs, develops, manufactures and 
maintains automated test systems that support the aerospace and defense, communications and mass transit industries as well as 
training and simulation devices for both commercial and military applications.
Principles of Consolidation
The Consolidated Financial Statements include the accounts of the Company and its wholly owned subsidiaries. All 
intercompany transactions and balances have been eliminated.
The Company accounts for its acquisitions under Accounting Standard Codification (“ASC”) Topic 805, Business 
Combinations and Reorganizations (“ASC Topic 805”). ASC Topic 805 provides guidance on how the acquirer recognizes and 
measures the consideration transferred, identifiable assets acquired, liabilities assumed, non-controlling interests, and goodwill 
acquired in a business combination. ASC Topic 805 also expands required disclosures surrounding the nature and financial 
effects of business combinations. There were no acquisitions in 2024, 2023 or 2022.
Cost of Products Sold, Research and Development and Selling, General and Administrative Expenses
Cost of Products Sold includes the costs to manufacture products such as direct materials and labor and manufacturing overhead 
as well as all engineering and developmental costs. The Company is engaged in a variety of research and development activities 
directed to the substantial improvement or new application of the Company’s existing technologies. Research and development 
costs are expensed as incurred and include salaries, benefits, consulting, material costs and depreciation. Research and 
development expenses amounted to $52.1 million in 2024, $53.5 million in 2023 and $48.3 million in 2022. These costs are 
included in Cost of Products Sold. SG&A expenses include costs primarily related to our sales, marketing and administrative 
departments. Interest expense is shown net of interest income. Interest income was insignificant for the years ended December 
31, 2024, 2023 and 2022.
Government Subsidies
In September 2021, the Company was awarded a grant of up to $14.7 million from the U.S. Department of Transportation 
(“USDOT”) under the Aviation Manufacturing Jobs Protection Program (“AMJP”). The Company received $7.3 million under 
the grant in 2022. The grant benefit was recognized ratably over the six-month performance period as a reduction to Cost of 
Products Sold in proportion to the compensation expense that the award was intended to defray. During the year ended 
December 31, 2022, the Company recognized $6.0 million of the award. There was no additional expense reduction recognized 
in 2024 or 2023.
Shipping and Handling
Shipping and handling costs are included in Cost of Products Sold.
Equity-Based Compensation
The Company accounts for its stock options following ASC Topic 718, Compensation – Stock Compensation (“ASC Topic 
718”). ASC Topic 718 requires all equity-based payments to employees, including grants of employee stock options and RSUs, 
to be recognized in the statement of earnings based on the grant date fair value of the award. For awards with graded vesting, 
the Company uses a straight-line method of attributing the value of stock-based compensation expense, subject to minimum 
levels of expense, based on vesting. The Company accounts for forfeitures as they occur.
48

Under ASC Topic 718, stock compensation expense recognized during the period is based on the value of the portion of share-
based payment awards that is ultimately expected to vest during the period. Equity-based compensation expense is included in 
SG&A Expenses.
Cash and Cash Equivalents
All highly liquid instruments with a maturity of three months or less at the time of purchase are considered cash equivalents.
Restricted Cash
Under the provisions of the ABL Revolving Credit Facility (as defined and discussed below in Note 8, Long-Term Debt), the 
Company has a cash dominion arrangement with the banking institution for its accounts within the United States whereby daily 
cash receipts are contractually utilized to pay down outstanding balances on the ABL Revolving Credit Facility. Account 
balances that have not yet been applied to the ABL Revolving Credit Facility are classified as restricted cash in the 
accompanying Consolidated Balance Sheets. The following table provides a reconciliation of cash and restricted cash included 
in Consolidated Balance Sheets to the amounts included in the Consolidated Statements of Cash Flows.

Customer Bankruptcies
In October 2024, a customer reported within the Aerospace segment declared bankruptcy. As a result, the Company recorded a 
full reserve of $1.0 million for outstanding receivables, a reserve of $1.7 million for inventory and $0.6 million for impairment 
of fixed assets.
In November 2023, a non-core contract manufacturing customer reported within the Aerospace segment filed for bankruptcy 
under Chapter 11. As a result, the Company recorded a full reserve of $7.5 million for outstanding accounts receivable and a 
reserve of $3.6 million for inventory. The associated assets existed prior to 2023.
Accounts Receivable and Allowance for Estimated Credit Losses
Accounts receivable are composed of trade and contract receivables recorded at either the invoiced amount or costs in excess of 
billings, are expected to be collected within one year, and do not bear interest. The Company records a valuation allowance to 
account for estimated credit losses. The estimate for credit losses is based on the Company’s assessment of the collectability of 
customer accounts. The Company regularly reviews the allowance by considering factors such as the age of the receivable 
balances, historical experience, credit quality, current economic conditions, and reasonable and supportable forecasts of future 
economic conditions that may affect a customer’s ability to pay. Balances are written off when determined to be uncollectible.
Although the Company has historically not experienced significant credit losses, the Company’s exposure to credit losses may 
increase if its customers are adversely affected by global economic recessions, industry conditions, or other customer-specific 
factors. 
Inventories
We record our inventories at the lower of cost or net realizable value. We determine the cost basis of our inventory on a first-in, 
first-out or weighted average basis using a standard cost methodology that approximates actual cost. The Company records 
reserves to provide for excess, slow moving or obsolete inventory. In determining the appropriate reserve, the Company 
considers the age of inventory on hand, the overall inventory levels in relation to forecasted demands as well as reserving for 
specifically identified inventory that the Company believes is no longer salable or whose value has diminished.
Cloud Computing Arrangements
The Company incurs costs to implement cloud computing arrangements that are hosted by third party vendors. Implementation 
costs associated with cloud computing arrangements are capitalized when incurred during the application development phase. 
Amortization is calculated on a straight-line basis over the contractual term of the cloud computing arrangement. Capitalized 
amounts related to such arrangements are recorded within Other Current Assets and other non-current assets in the 
Consolidated Balance Sheets and were insignificant as of December 31, 2024 and December 31, 2023.
49

Property, Plant and Equipment
Property, plant and equipment (“PP&E”) are recorded at cost less accumulated depreciation. Depreciation of property, plant and 
equipment is computed using the straight-line method for financial reporting purposes and using accelerated methods for 
income tax purposes. Estimated useful lives of the assets are as follows: buildings, 25-40 years; and machinery and equipment, 
4-10 years. Leased buildings and associated leasehold improvements are amortized over the shorter of the terms of the lease or 
the estimated useful lives of the assets, with the amortization of such assets included within depreciation expense.
The cost of properties sold or otherwise disposed of and the accumulated depreciation thereon are eliminated from the accounts 
and the resulting gain or loss, as well as maintenance and repair expenses, is reflected within operating income. Replacements 
and improvements are capitalized.
Depreciation expense was approximately $11.5 million, $12.2 million and $12.0 million in 2024, 2023 and 2022, respectively.
Deferred Financing Costs
The Company incurs debt issuance costs in connection with amending or entering into new credit facilities. These costs are 
amortized as an adjustment to interest expense over term of the credit facility on a straight-line basis, which approximates the 
effective interest method. This amortization expense is included in interest expense in the Company’s Consolidated Statements 
of Operations. Upon early termination or modification of a credit facility, all or a portion of unamortized fees related to such 
facility may be accelerated into interest expense or loss on debt extinguishment.
See Note 8, Long-Term Debt, for details of our deferred financing costs.
Long-Lived Assets
Long-lived assets to be held and used are initially recorded at cost. The carrying value of these assets is evaluated for 
recoverability whenever adverse effects or changes in circumstances indicate that the carrying amount may not be recoverable. 
Impairments are recognized if future undiscounted cash flows from operations are not expected to be sufficient to recover long-
lived assets. The carrying amounts are then reduced to fair value, which is typically determined by using a discounted cash flow 
model. 
Assets held for sale are to be reported at lower of its carrying amount or fair value less cost to sell. Judgment is required in 
estimating the sales price of assets held for sale and the time required to sell the assets. These estimates are based upon 
available market data and operating cash flows of the assets held for sale.
Goodwill
The Company tests goodwill at the reporting unit level on an annual basis or more frequently if an event occurs or 
circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. 
We may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for all or 
selected reporting units. If, after completing the assessment, it is determined that it is more likely than not that the fair value of a 
reporting unit is less than its carrying value, we proceed to a quantitative test. We may also elect to perform a quantitative test 
instead of a qualitative test for any or all of our reporting units.
Quantitative testing requires a comparison of the fair value of each reporting unit to its carrying value. We use the discounted 
cash flow method to estimate the fair value of our reporting units. The discounted cash flow method incorporates various 
assumptions, the most significant being projected sales growth rates, operating margins and cash flows, the terminal growth rate 
and the weighted average cost of capital, which are Level 3 inputs in the fair value hierarchy. If the carrying value of the 
reporting unit exceeds its fair value, goodwill impairment is measured as the amount by which the reporting unit’s carrying 
value exceeds its fair value, not to exceed the carrying value of goodwill. 
The 2024, 2023 and 2022 assessments indicated no impairment to the carrying value of goodwill in any of the Company’s 
reporting units and no impairment charges were recognized.
Intangible Assets
The estimated fair values of acquired intangibles are generally determined based upon future economic benefits such as 
earnings and cash flows. Acquired identifiable intangible assets are recorded at fair value and are amortized over their estimated 
useful lives. Acquired intangible assets with an indefinite life are not amortized, but are reviewed for impairment at least 
annually or more frequently whenever events or changes in circumstances indicate that the carrying amounts of those assets are 
50

below their estimated fair values. Impairment is tested under ASC Topic 350, Intangibles - Goodwill and Other, as amended by 
ASU 2012-2.
The 2024, 2023 and 2022 assessments indicated no impairment to the intangible assets in any of the Company’s reporting units 
and no impairment charges were recognized.
Financial Instruments
The Company’s financial instruments consist primarily of cash and cash equivalents, restricted cash, accounts receivable, 
accounts payable and long-term debt. The Company performs periodic credit evaluations of its customers’ financial condition 
and generally does not require collateral. The Company does not hold or issue financial instruments for trading purposes. Due 
to their short-term nature, the carrying values of cash and equivalents, restricted cash, accounts receivable and accounts payable 
approximate fair value. The carrying value of the Company’s variable rate long-term debt instruments also approximates fair 
value due to the variable rate feature of these instruments. The fair value of the Convertible Senior Notes due 2030 (the 
“Convertibles Notes”) was approximately $176.9 million as of December 31, 2024 based on quoted prices for these instruments 
in active markets, and is classified as a Level 1 measurement within the fair value hierarchy.
From time to time, the Company makes long-term, strategic equity investments in companies to promote business and strategic 
objectives. These investments as classified within other assets in the Consolidated Balance Sheets. For investments requiring 
equity method accounting, we recognize our share of the investee’s earnings or losses within Other Expense, Net of Other 
Income in the Consolidated Statements of Operations. For investments not requiring equity method accounting, if the 
investment has no readily determinable fair value, we have elected the practicability exception of ASU 2016-01, under which 
the investment is measured at cost, less impairment, plus or minus observable price changes from orderly transactions of an 
identical or similar investment of the same issuer.
We recognized income of $1.8 million associated with the reversal of a liability related to an equity investment, as we were no 
longer required to make an associated payment. This amount is included in Other Expense, Net of Other Income in the 
Consolidated Statement of Operations in 2023. Our ownership percentage in this company was diluted during 2023, thus our 
equity investment was converted to the cost method. 
Deferred Tax Asset Valuation Allowance
The Company records a valuation allowance against the deferred tax assets if and to the extent it is more likely than not that the 
Company will not recover the deferred tax assets. In evaluating the need for a valuation allowance, the Company weighs all 
relevant positive and negative evidence, and considers among other factors, historical financial performance, projected future 
taxable income, scheduled reversals of deferred tax liabilities, the overall business environment, and tax planning strategies. 
After considering the losses in recent periods and cumulative pre-tax losses in the three-year period ending with the current 
year, the Company determined that projections of future taxable income could not be relied upon as a source of income to 
realize its deferred tax assets. However, the Company is relying on a significant portion of its existing deferred tax liabilities for 
the realizability of deferred tax assets. As a result, the Company has valuation allowances against its deferred tax assets of 
approximately $78.7 million, $65.6 million, and $57.4 million during the years ended December 31, 2024, 2023 and 2022, 
respectively, for the portion of deferred tax asset not realizable by the Company’s existing deferred tax liabilities. 
Use of Estimates
The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) 
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure 
of contingent liabilities and the reported amounts of sales and expenses during the reporting periods in the financial statements 
and accompanying notes. Actual results could differ from those estimates.
Foreign Currency Translation
The Company accounts for its foreign currency translation in accordance with ASC Topic 830, Foreign Currency Translation. 
The aggregate transaction gains and losses included in operations were insignificant in 2024, 2023 and 2022.
Dividends
The Company has not paid any cash dividends in the three-year period ended December 31, 2024.
51

Loss Contingencies
Loss contingencies may from time to time arise from situations such as claims and other legal actions. Loss contingencies are 
recorded as liabilities when it is probable that a liability has been incurred and the amount of the loss is reasonably estimable. In 
all other instances, legal fees are expensed as incurred. Disclosure is required when there is a reasonable possibility that the 
ultimate loss will exceed the recorded provision. Contingent liabilities are often resolved over long time periods. In recording 
liabilities for probable losses, management is required to make estimates and judgments regarding the amount or range of the 
probable loss. Management continually assesses the adequacy of estimated loss contingencies and, if necessary, adjusts the 
amounts recorded as better information becomes known.

NOTE 2 — REVENUE
Revenue is recognized when, or as, the Company transfers control of promised products or services to a customer in an amount 
that reflects the consideration the Company expects to be entitled in exchange for transferring those products or services. Sales 
shown on the Company’s Consolidated Statements of Operations are from contracts with customers.
Payment terms and conditions vary by contract, although terms generally include a requirement of payment within a range from 
30 to 90 days after the performance obligation has been satisfied; or in certain cases, up-front deposits. In circumstances where 
the timing of revenue recognition differs from the timing of receipt of consideration, the Company has determined that the 
Company’s contracts generally do not include a significant financing component. Taxes collected from customers, which are 
subsequently remitted to governmental authorities, are excluded from sales.
The Company recognizes an asset for the incremental, material costs of obtaining a contract with a customer if the Company 
expects the benefit of those costs to be longer than one year and the costs are expected to be recovered. These incremental costs 
include, but are not limited to, sales commissions incurred to obtain a contract with a customer. The Company has elected the 
practical expedient available under ASC 340-40-25-4 to immediately expense the incremental cost of obtaining a contract when 
the expected benefit of those costs is less than one year. As of December 31, 2024 and 2023, the Company did not have 
material incremental costs on any open contracts with an original expected duration of greater than one year.
The Company recognizes an asset for certain, material costs to fulfill a contract if it is determined that the costs relate directly to 
a contract or an anticipated contract that can be specifically identified, generate or enhance resources that will be used in 
satisfying performance obligations in the future, and are expected to be recovered. Such costs are amortized on a systematic 
basis that is consistent with the transfer to the customer of the goods to which the asset relates. Start-up costs are expensed as 
incurred. Capitalized fulfillment costs are included in Inventories in the accompanying Consolidated Balance Sheets. Should 
future orders not materialize or it is determined the costs are no longer probable of recovery, the capitalized costs are written 
53

off. The Company has capitalized $8.3 million and $4.7 million of costs as of December 31, 2024 and 2023, respectively. 
Amortization of fulfillment costs recognized within Cost of Products Sold was $3.1 million in 2024. No amortization of 
fulfillment costs was recorded in 2023 or 2022.
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. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or 
services is not separately identifiable from other promises in the contracts which are, therefore, not distinct. Thus, the contract’s 
transaction price is the revenue recognized when or as that performance obligation is satisfied. Promised goods or services that 
are immaterial in the context of the contract are not separately assessed as performance obligations.
Some of our contracts have multiple performance obligations, most commonly due to the contract covering multiple phases of 
the product lifecycle (development, production, maintenance and support). For contracts with multiple performance obligations, 
the contract’s transaction price is allocated 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 standalone selling price is the 
expected cost plus margin approach, under which expected costs are forecast to satisfy a performance obligation and then an 
appropriate margin is added for that distinct good or service. Shipping and handling activities that occur after the customer has 
obtained control of the good are considered fulfillment activities, not performance obligations.
Some of our contracts offer price discounts or free units after a specified volume has been purchased. The Company evaluates 
these options to determine whether they provide a material right to the customer, representing a separate performance 
obligation. If the option provides a material right to the customer, revenue is allocated to these rights and recognized when 
those future goods or services are transferred, or when the option expires.
Contract modifications are routine in the performance of our contracts. Contracts are often modified to account for changes in 
contract specifications or requirements. In most instances, contract modifications are for goods or services that are distinct, and, 
therefore, are accounted for as new contracts. The effect of modifications has been reflected when identifying the satisfied and 
unsatisfied performance obligations, determining the transaction price and allocating the transaction price.
The majority of the Company’s revenue from contracts with customers is recognized at a point in time, when the customer 
obtains control of the promised product. In general, the customer has obtained control when they have legal title, significant 
risks and rewards of ownership of the asset, and the Company has a present right to payment for the product. These contracts 
may provide credits or incentives, which may be accounted for as variable consideration. Variable consideration is estimated at 
the most likely amount to predict the consideration to which the Company will be entitled, and only to the extent it is probable 
that a subsequent change in estimate will not result in a significant revenue reversal when estimating the amount of revenue to 
recognize. Variable consideration is treated as a change to the sales transaction price and based on an assessment of all 
information (i.e., historical, current and forecasted) that is reasonably available to the Company, and estimated at contract 
inception and updated at the end of each reporting period as additional information becomes available. Most of our contracts do 
not contain rights to return product; where this right does exist, it is evaluated as possible variable consideration.
For contracts that are subject to the requirement to accrue anticipated losses, the Company recognizes the entire anticipated loss 
in the period that the loss becomes probable.
For contracts with customers in which the Company promises to provide a product to the customer that has no alternative use to 
the Company and the Company has enforceable rights to payment for progress completed to date inclusive of profit, the 
Company satisfies the performance obligation and recognizes revenue over time, using costs incurred to date relative to total 
estimated costs at completion to measure progress toward satisfying our performance obligations. Incurred cost represents work 
performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Contract costs include 
labor, material and overhead.
The Company also recognizes revenue from service contracts (including service-type warranties) over time. The Company 
recognizes revenue over time during the term of the agreement as the customer is simultaneously receiving and consuming the 
benefits provided throughout the Company’s performance. The Company typically recognizes revenue over time using a cost-
to-cost method, where revenues are recognized proportionally as costs are incurred, or on a straight-line basis throughout the 
contract period.
On December 31, 2024, we had $599.2 million of remaining performance obligations, which we refer to as total backlog. We 
expect to recognize approximately $488.8 million of our remaining performance obligations as revenue in 2025.
Costs in excess of billings includes unbilled amounts resulting from revenues under contracts with customers that are satisfied 
over time and when the cost-to-cost measurement method of revenue recognition is utilized and revenue recognized exceeds the 
amount billed to the customer, and right to payment is not just subject to the passage of time. Amounts may not exceed their net 
54

realizable value. Costs in excess of billings are classified as current assets, within Accounts Receivable, Net of Allowance for 
Estimated Credit Losses on our Consolidated Balance Sheets.
Billings in excess of cost includes billings in excess of revenue recognized as well as other elements of deferred revenue, which 
includes advanced payments, up-front payments, and progress billing payments. Billings in excess of cost are reported in our 
Consolidated Balance Sheets classified as current liabilities, within Customer Advance Payments and Deferred Revenue, and 
non-current liabilities, within Other Liabilities. To determine the revenue recognized in the period from the beginning balance 
of billings in excess of cost, the contract liability as of the beginning of the period is recognized as revenue on a contract-by-
contract basis when the Company satisfies the performance obligation related to the individual contract. Once the beginning 
contract liability balance for an individual contract has been fully recognized as revenue, any additional payments received in 
the period are recognized as revenue once the related costs have been incurred.
The Company's contract assets and contract liabilities consist primarily of costs and profits in excess of billings and billings in 
excess of cost and profits, respectively. The following table presents the beginning and ending balances of contract assets and 
contract liabilities:

The increase in contract assets reflects the net impact of new revenue recognized in excess of billings exceeding billing of 
previously unbilled revenue during the period, partially offset by a $3.5 million revision of estimated costs to complete certain 
long-term mass transit Test contracts which was recorded in the second quarter of 2024. The revision resulted in reduced 
revenue recognized during 2024 due to lower estimates of the percentage of work completed on the programs. The increase in 
contract liabilities reflects the net impact of new customer advances or deferred revenues recorded in excess of revenue 
recognized.
We recognized $16.8 million and $27.6 million during the year ended December 31, 2024 and 2023, respectively, in revenues 
that were included in the contract liability balance at the beginning of the period.

The Company’s four reporting units with goodwill as of the first day of our fourth quarters of 2024, 2023 and 2022 were 
subject to the annual goodwill impairment test. Based on our quantitative assessments of our reporting units performed during 
our annual goodwill impairment tests, the Company concluded that no impairment to the carrying value of goodwill in any of 
the Company’s reporting units was indicated and no impairment charges were recognized in 2024, 2023 and 2022.
NOTE 8 — LONG-TERM DEBT
The Company amended its asset-based revolving credit facility (the “ABL Revolving Credit Facility”) on July 11, 2024, by 
entering into the Seventh Amended and Restated Credit Agreement, which set the maximum aggregate amount that the 
Company can borrow pursuant to the revolving credit line at $200.0 million, with borrowings subject to a borrowing base 
determined primarily by inventory, accounts receivable, machinery and equipment and real estate. The Company also entered 
into a $55.0 million Term Loan Facility on July 11, 2024. The Company repaid in full all outstanding indebtedness under the 
previous term loan dated January 19, 2023. The payoff amount of approximately $84.5 million consisted of a repayment of the 
principal amount of approximately $80.3 million, plus accrued but unpaid interest, fees and expenses, including a call premium 
of 4.00% which satisfied all of the Company’s indebtedness obligations thereunder. The Company funded the repayment of its 
obligations under the previous agreement with borrowings under the ABL Revolving Credit Facility and the Term Loan 
Facility.
On November 25, 2024, the Company entered into a second amendment to the ABL Revolving Credit Facility which increased 
the maximum aggregate amount that the Company can borrow pursuant to the ABL Revolving Credit Facility to $220.0 million 
from $200.0 million. The maturity date of borrowings under the ABL Revolving Credit Facility remains July 11, 2027. The 
Company and the applicable lenders also agreed in a separate first amendment to increase the amount of unsecured 
indebtedness the Company is permitted to incur under the ABL Revolving Credit Facility, subject to completion of the 
Convertible Notes offering (discussed below).
Under the terms of the ABL Revolving Credit Facility, the Company pays interest on the unpaid principal amount of the ABL 
Revolving Credit Facility at a rate equal to SOFR plus a term SOFR adjustment in the amount of 0.10% per annum (which 
collectively shall be at least 1.00%) plus an applicable margin ranging from 2.75% to 3.25% determined based upon the 
Company’s Excess Availability (as defined in the ABL Revolving Credit Facility). The Company is required to pay a quarterly 
commitment fee under the ABL Revolving Credit Facility on undrawn revolving credit commitments in an amount equal to 
0.25% or 0.375% based on the Company’s average excess availability under the ABL Revolving Credit Facility. On December 
31, 2024, there was $10.0 million outstanding on the ABL Revolving Credit Facility and there remained $209.7 million 
available for future borrowings, net of outstanding letters of credit, before our minimum excess availability requirement 
discussed below.
Pursuant to the ABL Revolving Credit Facility, the Company is subject to a minimum fixed charge coverage ratio of 1.10 to 
1.00. The Company is also required to maintain minimum excess availability of the greater of 10% of the borrowing base under 
the ABL Revolving Credit Facility, or $15.0 million. As of December 31, 2024, the Company was in compliance with these 
covenants.
On December 3, 2024, the Company issued $165.0 million aggregate principal amount of the Convertible Notes, which amount 
includes the additional Convertible Notes issued pursuant to the initial purchasers’ full exercise of their option to purchase 
additional Convertible Notes. The Convertible Notes bear interest at a rate of 5.500% per annum, payable semi-annually in 
arrears on March 15 and September 15 of each year, beginning on March 15, 2025. The Convertible Notes will mature on 
58

March 15, 2030, unless earlier converted, redeemed or repurchased. The initial conversion rate is 43.6814 shares of common 
stock per $1,000 principal amount of Convertible Notes, which represent the initial conversion price of $22.89 per share. The 
Convertible Notes are convertible at the option of the holders at any time on or after December 15, 2029, until the close of 
business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, the Company will 
satisfy its conversion obligations by paying and/or delivering, as the case may be, cash, shares of its common stock or a 
combination of cash and shares of its common stock, at its election. Beginning March 20, 2028, if the Company’s stock price 
has been at least 130% of the conversion price for a specified period of time, the Convertible Notes may be called at the option 
of the issuer. Under the same conditions, the Company can elect to redeem the Convertible Notes for cash. After the first 
quarter of 2025, if the Company’s stock price has been at least 130% of the conversion price for 20 of 30 trading days ending 
on and including the last trading day of the immediately preceding quarter, the Convertible Notes may be called at the option of 
the holder. The fair value of the Convertible Notes was approximately $176.9 million as of December 31, 2024 based on quoted 
prices for these instruments in active markets, and is classified as a Level 1 measurement within the fair value hierarchy.
On December 3, 2024, the Company repaid in full all outstanding indebtedness under the Term Loan Facility. The Term Loan 
Facility payoff consisted of a repayment of a principal amount of approximately $54.9 million, plus accrued but unpaid interest, 
fees and expenses, including a call premium of 3.00% which satisfied all of the Company’s indebtedness obligations 
thereunder. The Company funded the repayment of its obligations under the Term Loan Facility with a portion of the proceeds 
received from the issuance and sale of the Convertible Notes. Scheduled principal payments of $9.0 million were payable under 
the Term Loan Facility and were classified as current in the accompanying Consolidated Balance Sheets as of December 31, 
2023. The interest rate on current maturities of long-term debt was 14.20% at December 31, 2023.
The Company incurred $12.2 million in incremental debt issuance costs during 2024. All costs are amortized to interest expense 
over the term of the respective agreement. Debt issuance cost amortization expense was approximately $2.6 million, 
$3.0 million and $0.8 million in 2024, 2023 and 2022, respectively. Unamortized deferred debt issuance costs associated with 
the ABL Revolving Credit Facility ($3.0 million as of December 31, 2024) are recorded within Other Assets and those 
associated with the Convertible Notes ($6.3 million as of December 31, 2024) are recorded as a reduction of the carrying value 
of the debt on the Consolidated Balance Sheets. The unamortized balance of deferred debt issuance costs on our previous credit 
facilities of $2.0 million was recorded within Other Assets and $4.3 million was recorded as a reduction of the carrying value of 
the debt on the Consolidated Balance Sheets at December 31, 2023.
In 2024, the Company recorded a loss on extinguishment of the debt of approximately $10.1 million below Income from 
Operations, which was comprised of $4.5 million of prepayment fees on the previous term loans and a write-off of $5.6 million 
of unamortized deferred financing costs. The Company also had a write-off of deferred financing costs of approximately 
$0.5 million related to the exiting ABL lender in Interest Expense within the Consolidated Statements of Operations.
Certain of the Company’s subsidiaries are borrowers under the ABL Revolving Credit Facility and the assets of such 
subsidiaries also secure the obligations under the ABL Revolving Credit Facility. In the event of voluntary or involuntary 
bankruptcy of the Company or any subsidiary, all unpaid principal and other amounts owing under the credit facilities 
automatically become due and payable. Other events of default, such as failure to make payments as they become due and 
breach of financial and other covenants, change of control, cross default under other material debt agreements, and a going 
concern qualification for any reason other than loan maturity date give the agent the option to declare all such amounts 
immediately due and payable.
NOTE 9 — WARRANTY
In the ordinary course of business, the Company warrants its products against defects in design, materials and workmanship 
typically over periods ranging from twelve to sixty months. The Company determines warranty reserves needed by product line 
based on experience and current facts and circumstances. Activity in the warranty accrual, which is included in Other Accrued 
Expenses on the Consolidated Balance Sheets, is summarized as follows:

NOTE 10 — LEASES
The Company has operating and finance leases for leased office and manufacturing facilities and equipment leases. We have 
concluded that when an agreement grants us the right to substantially all of the economic benefits associated with an identified 
asset, and we are able to direct the use of that asset throughout the term of the agreement, we have a lease. We lease certain 
office equipment under finance leases, and we lease certain production facilities, office equipment and vehicles under operating 
leases. Some of our leases include options to extend or terminate the leases and these options have been included in the relevant 
lease term to the extent that they are reasonably certain to be exercised.
If the lease arrangement also contains non-lease components, the Company elected the practical expedient not to separate any 
combined lease and non-lease components for all lease contracts. For our real estate leases, the payments used in the calculation 
of a new lease liability include fixed payments and variable payments (if the variable payments are based on an index) over the 
remaining lease term. Variable lease payments based on indices have been included in the related right-of-use assets and lease 
liabilities on our Consolidated Balance Sheets, while variable lease payments based on usage of the underlying asset have been 
excluded and are expensed in the period they are incurred, as they do not represent present rights or obligations. Variable lease 
components for leases relate primarily to common area maintenance charges and other separately billed lessor services, sales 
and real estate taxes.
Any new additional operating and financing lease liabilities and corresponding right-of-use (“ROU”) assets are based on the 
present value of the remaining minimum rental payments. The Company’s operating lease liability increased approximately 
$1.0 million as a result of acquiring ROU assets from new leases entered into during the year ended December 31, 2024. In 
determining the incremental borrowing rate, we have considered borrowing data for secured debt obtained from our lending 
institution.

The weighted-average remaining term for the Company’s operating and financing leases are approximately 7 years and 1 year, 
respectively. The weighted-average discount rates for the Company’s operating and financing leases are approximately 5.8% 
and 6.3%, respectively.

NOTE 11 — INCOME TAXES
The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences 
between the financial reporting and tax basis of assets and liabilities. Deferred tax assets are reduced, if deemed necessary, by a 
valuation allowance for the amount of tax benefits which are not more likely than not to be realized.

The Company records a valuation allowance against the deferred tax assets if and to the extent it is more likely than not that the 
Company will not recover the deferred tax assets. In evaluating the need for a valuation allowance, the Company weighs all 
relevant positive and negative evidence, and considers among other factors, historical financial performance, projected future 
taxable income, scheduled reversals of deferred tax liabilities, the overall business environment, and tax planning strategies. 
After considering the losses in recent periods and cumulative pre-tax losses in the three-year period ending with the current 
year, the Company determined that projections of future taxable income could not be relied upon as a source of income to 
realize its deferred tax assets. However, the Company is relying on a significant portion of its existing deferred tax liabilities for 
the realizability of deferred tax assets. As a result, the Company has valuation allowances against its deferred tax assets of 
approximately $78.7 million, $65.6 million, and $57.4 million during the years ended December 31, 2024, 2023 and 2022, 
respectively, for the portion of deferred tax assets not realizable by the Company’s existing deferred tax liabilities.
Beginning January 1, 2022, the Tax Cuts and Jobs Act (TCJA) of 2017 eliminated the option to deduct research and 
development expenditures in the current year and now requires taxpayers to capitalize and amortize research and development 
costs pursuant to Internal Revenue Code (“IRC”) Section 174. The capitalized expenses are amortized over a 5-year period for 
domestic expenses and a 15-year period for foreign expenses. As a result of this provision of the TCJA, deferred tax assets 
related to capitalized research expenses increased by approximately $9.4 million and $5.8 million during the years ended 
December 31, 2024 and 2023, respectively. The Company maintains a full valuation allowance against this deferred tax asset.
63

At December 31, 2024, gross federal net operating losses amounted to approximately $1.1 million, which are subject to annual 
limitations under Internal Revenue Code Section 382. Of these net operating losses, $0.7 million expire in 2038 and the 
remaining $0.4 million will carryforward indefinitely. The Company maintains a full valuation allowance against this deferred 
tax asset.
At December 31, 2024, gross state net operating loss carryforwards amounted to approximately $132.6 million. Of these state 
net operating loss carryforwards, $118.9 million begin to expire at various dates from 2024 through 2044 and the remaining 
$13.7 million will carryforward indefinitely. The Company maintains a full valuation allowance against this deferred tax asset.
At December 31, 2024, state income tax credit carryforwards amounted to approximately $1.1 million and begin to expire at 
various dates from 2024 to 2040. Additionally, the Company has approximately $0.2 million of foreign tax credits that it can 
carry forward through 2027. The Company maintains a full valuation allowance against these credits.
The Company has analyzed its filing positions in all of the federal and state jurisdictions where it is required to file income tax 
returns, as well as all open tax years in these jurisdictions. Should the Company need to accrue a liability for uncertain tax 
benefits, any interest and penalties associated with that liability would be recorded as income tax expense. A reconciliation of 
the total amounts of unrecognized tax benefits, excluding interest and penalties, is as follows:

There are no material penalties or interest liabilities accrued as of December 31, 2024, 2023, or 2022, nor are any material 
penalties or interest costs included in expense for each of the years ended December 31, 2024, 2023 and 2022. The years under 
which we conducted our evaluation coincided with the tax years currently still subject to examination by major federal and state 
tax jurisdictions, those being 2019 through 2024 for federal purposes and 2017 through 2024 for state purposes.
Pretax income from the Company’s foreign subsidiaries amounted to approximately $9.6 million, $6.5 million and $0.1 million 
for 2024, 2023 and 2022, respectively. The balance of pretax earnings or loss for each of those years were domestic.
Historically, we have asserted that the unremitted earnings of our foreign subsidiaries were indefinitely reinvested. However, 
for the years ended December 31, 2024 and 2023, we determined that we could no longer assert indefinite reinvestment on 
approximately $3.0 million and $1.9 million of the unremitted earnings of Luminescent Systems Canada Inc., respectively. As a 
result, we have recorded a deferred tax liability of approximately $0.2 million and $0.1 million at December 31, 2024 and 2023 
respectively, related to local country withholding taxes that are expected to be incurred upon ultimate repatriation of such 
earnings. All other foreign unremitted earnings, which total approximately $18.7 million, continue to be indefinitely reinvested. 
We continue to be permanently reinvested in outside basis differences other than unremitted earnings as we have no plans to 
liquidate or sell any foreign subsidiaries. In addition, we have not provided deferred taxes on any outside basis differences of 
our domestic subsidiaries as we have the ability and intent to recover these basis differences in a tax-free manner. It is not 
practicable to determine the amount of unrecognized deferred tax related to these basis differences.
The Inflation Reduction Act of 2022 (IRA) was signed into law on August 16, 2022. Key provisions under the IRA include a 
15% corporate alternative minimum tax imposed on certain large corporations and the extension and expansion of clean energy 
tax incentives. There were no impacts related to the IRA recorded for the years ending December 31, 2024, 2023, and 2022. 
Under an Organization for Economic Co-operation and Development Inclusive Framework, countries that agreed to enact a 
two-pillar solution aim to address the challenges arising from the digitalization of the world economy (Pillar Two). Pillar Two 
sets out global minimum Effective Tax Rate (ETR) rules to ensure that large multinational businesses with consolidated 
revenue over €750 million are subject to a minimum ETR of 15% on income arising in low-tax jurisdictions. Rules under Pillar 
Two generally became effective beginning January 1, 2024 in most jurisdictions that have issued legislation. The Company will 
continue to monitor the impact of Pillar Two; however, Pillar Two is currently not applicable as the Company does not meet the 
threshold of having consolidated revenue over €750 million in two out of the four preceding years.
NOTE 12 — PROFIT SHARING/401K PLAN
The Company offers eligible domestic full-time employees participation in a safe harbor 401K plan. The plan provides for an 
annual company contribution. In addition, employees may contribute a portion of their salary to the plan. The plan may be 
amended or terminated at any time.
64

Total charges to income before income taxes for this plan was approximately $8.9 million, $5.3 million and $4.7 million in 
2024, 2023 and 2022, respectively. The Company had funded the contributions in 2022, 2023 and the first quarter of 2024 with 
treasury stock in lieu of cash and funded the remainder of the 2024 contributions with cash.
NOTE 13 — RETIREMENT PLANS AND RELATED POST RETIREMENT BENEFITS
The Company has two non-qualified supplemental retirement defined benefit plans (“SERP” and “SERP II”) for certain current 
and retired executive officers. The accumulated benefit obligation of the plans as of December 31, 2024 and 2023 amounts to 
$21.4 million and $22.0 million, respectively.
The plans provide for benefits based upon average annual compensation and years of service and, in the case of SERP, there are 
offsets for social security and profit sharing benefits. It is the Company’s intent to fund the plans as plan benefits become 
payable, since no assets exist at December 31, 2024 or 2023 for either of the plans.
The Company accounts for the funded status (i.e., the difference between the fair value of plan assets and the projected benefit 
obligations) of its pension plans in accordance with the recognition and disclosure provisions of ASC Topic 715, 
Compensation, Retirement Benefits, which requires the Company to recognize the funded status in its balance sheet, with a 
corresponding adjustment to Accumulated Other Comprehensive Income (“AOCI”), net of tax. These amounts will be 
subsequently recognized as net periodic pension cost pursuant to the Company’s historical policy for amortizing such amounts. 
Further, actuarial gains and losses that arise in subsequent periods and are not recognized as net periodic pension cost in the 
same periods will be recognized as a component of AOCI. If actuarial gains and losses exceed ten percent of the projected 
benefit obligation, we amortize them over the average expected future lifetime of participants.
Unrecognized prior service costs of $0.3 million and unrecognized actuarial gains of $4.9 million are included in AOCI at 
December 31, 2024 and have not yet been recognized in net periodic pension cost. 
The reconciliation of the beginning and ending balances of the projected benefit obligation of the plans for the years ended 
December 31 is as follows:

In 2024, the net actuarial gain of $6.1 million is due to the increase of 69 basis points in the discount rate and change in the 
bonus scale used to measure the benefit obligation as of December 31, 2024 compared to the prior year. The Company incurred 
charges of $0.6 million in 2024 associated with a waiver of an early retirement penalty provided by the plan related to a retiring 
participant. The assumptions used to calculate the projected benefit obligation as of December 31 are as follows:

5.48%

The plans are unfunded at December 31, 2024 and are recognized in the accompanying Consolidated Balance Sheets as a 
current accrued pension liability of $1.0 million and a long-term accrued pension liability of $23.3 million.
The service cost component of net periodic benefit cost is included in SG&A expenses, and all other net periodic benefit costs 
components (such as interest cost, prior service cost amortization and actuarial gain/loss amortization) are reported outside of 
operating income, within Other (Income) Expense, Net in the accompanying Consolidated Statements of Operations.

are $9.5 million. Given that the plans are unfunded, these amounts are what the Company expects to contribute to the plans in 
each respective year.
Participants in the SERP are entitled to paid medical, dental and long-term care insurance benefits upon retirement under the 
plan. The measurement date for determining the plan obligation and cost is December 31. The accumulated postretirement 
benefit obligation is $0.8 million at December 31, 2024 and 2023. The plan is recognized in the accompanying Consolidated 
Balance Sheets as a current accrued pension liability of $0.1 million and a long-term accrued pension liability of $0.7 million. 
The net periodic cost for the years ended December 31, 2024, 2023 and 2022 was not material.
The Company is a participating employer in a trustee-managed multiemployer defined benefit pension plan for employees who 
participate in collective bargaining agreements. The plan generally provides retirement benefits to employees based on years of 
service to the Company. Contributions are based on the hours worked and are expensed on a current basis. The plan is 95.3% 
funded as of January 1, 2024. The Company’s contributions to the plan were $0.9 million in 2024, $0.7 million in 2023 and 
$0.5 million in 2022. These contributions represent less than 1% of total contributions to the plan.
NOTE 14 — SHAREHOLDERS’ EQUITY
Share Buyback Program
The Company’s Board of Directors from time to time authorizes the repurchase of common stock, which allows the Company 
to purchase shares of its common stock in accordance with applicable securities laws on the open market or through privately 
negotiated transactions. The Company has the capacity under the currently authorized program to repurchase additional shares 
of its common stock with a maximum dollar value of $41.5 million. 
At-the-Market Equity Offering
On August 8, 2023, the Company initiated an at-the-market equity offering program (the “ATM Program”) for the sale from 
time to time of shares of the Company’s common stock, par value $0.01 per share having an aggregate offering price of up to 
$30.0 million. During the year ended December 31, 2023, the Company sold 1,334,228 shares of our Common Stock under the 
ATM Program. The Company generated $21.8 million in aggregate gross proceeds from sales under the ATM Program at an 
average sale price of $16.31 per share of Common Stock. Aggregate net proceeds from the ATM Program were $21.3 million 
after deducting related expenses, including commissions to the Sales Agents and issuance costs. No shares were sold under the 
ATM Program in 2024. As of December 31, 2024, the Company had remaining capacity under the ATM Program to sell shares 
of Common Stock having an aggregate offering price up to approximately $8.2 million.
Reserved Common Stock
At December 31, 2024, approximately 8.1 million shares of Common Stock were reserved for issuance upon conversion of the 
Class B stock, exercise of stock options, issuance of restricted stock and purchases under the Employee Stock Purchase Plan. 
Class B Stock is identical to Common Stock, except Class B Stock has ten votes per share, is automatically converted to 
Common Stock on a one-for-one basis when sold or transferred other than via gift, devise or bequest and cannot receive 
dividends unless an equal or greater amount of dividends is declared on Common Stock.

Stock options with exercise prices greater than the average market price of the underlying common shares are excluded from 
the computation of diluted earnings per share because they are out-of-the-money and the effect of their inclusion would be anti-
dilutive. The Company includes the dilutive effect of shares issuable upon conversion of its Convertible Notes in the calculation 
of diluted income per share using the if-converted method. The Company has the option for the Convertible Notes to settle the 
conversion value in any combination of cash or shares, and as such, the maximum number of shares issuable are included in the 
dilutive share count if the effect would be dilutive. The Company incurred a net loss for the years ended December 31, 2024, 
2023, and 2022, therefore all outstanding stock options, unvested restricted stock units and the effect of the Convertible Notes 
are excluded from the computation of diluted loss per share because the effect of their inclusion would be antidilutive.

NOTE 16 — EQUITY COMPENSATION
The Company has equity compensation plans that authorize the issuance of restricted stock units or options for shares of 
Common Stock to directors, officers and key employees. Equity-based compensation is designed to reward long-term 
contributions to the Company and provide incentives for recipients to join and to remain with the Company. The exercise price 
of stock options, determined by a committee of the Board of Directors, is equal to the fair market value of the Common Stock 
on the grant date. Options become exercisable over periods not exceeding ten years and must be exercised within ten years from 
the grant date. The Company’s practice has been to issue new shares upon the exercise of the options.
The Company established its 2011 Incentive Stock Option Plan for the purpose of attracting and retaining executive officers 
and key employees, and to align management’s interest with those of the shareholders. At December 31, 2024, the Company 
had options outstanding for 124,143 shares under the plans. 
The Company established the 2005 Directors Stock Option Plan for the purpose of attracting and retaining the services of 
experienced and knowledgeable outside directors, and to align their interest with those of the shareholders. At December 31, 
2024, the Company had options outstanding for 28,254 shares under the plans. 
During 2017, the Company established the Astronics Corporation 2017 Long Term Incentive Plan for the purpose of attracting 
and retaining directors, executive officers and key employees, and to align management’s interest with those of the 
shareholders. The Long Term Incentive Plan contemplates the use of a mix of equity award types. For stock options, the 
exercise price is equal to the share price on the date of grant. Upon inception, the remaining options available for future grant 
under the 2011 Incentive Stock Option Plan and the 2005 Directors Stock Option Plan were rolled in the Long Term Incentive 
Plan, and no further grants may be made out of those plans. The Long Term Incentive Plan was amended and restated in May 
2021. At December 31, 2024, the Company had stock options and RSUs outstanding that covered 1,963,720 shares under the 
Long Term Incentive Plan, and there were 278,560 shares available for future grant under this plan.
Stock compensation expense recognized during the period is based on the value of the portion of share-based payment awards 
that is ultimately expected to vest during the period. Vesting requirements vary for directors, officers and key employees. In 
general, options or RSUs granted to outside directors vest six months from the date of grant and options granted to officers and 
key employees straight line vest over a three- to five-year period from the date of grant. RSUs granted to officers and key 
employees generally cliff vest three years from the date of grant.

Company entered into a Transition and Retirement Agreement with its former CFO, which granted certain benefits related to 
the retirement. Equity-based Compensation Expense includes $0.6 million related with accelerated RSU vesting pursuant to that 
Agreement.

To determine expected volatility, the Company uses historical volatility based on weekly closing prices of its Common Stock 
and considers currently available information to determine if future volatility is expected to differ over the expected terms of the 
options granted. The risk-free rate is based on the U.S. Treasury yield curve at the time of grant for the appropriate term of the 
options granted. Expected dividends are based on the Company’s history and expectation of dividend payouts. The expected 
term of stock options is based on vesting schedules, expected exercise patterns and contractual terms.

The aggregate intrinsic value in the preceding table represents the total pretax option holder’s intrinsic value, based on the 
closing stock price of the Company’s Common Stock which would have been received by the option holders had all option 
holders exercised their options as of that date. The closing stock price of the Company’s Common Stock was $15.96, $17.42 
and $10.30 as of December 31, 2024, 2023 and 2022, respectively. As the stock price of $15.96 was below the weighted 
average exercise price, intrinsic value is zero.
The weighted average fair value of options vested during 2024, 2023 and 2022 was $7.30, $11.53 and $12.89, respectively. The 
total fair value of options that vested during the year amounted to $2.1 million, $3.0 million and $2.4 million for the years 
ended December 31, 2024, 2023 and 2022, respectively. At December 31, 2024, total compensation costs related to non-vested 
option awards not yet recognized amounts to $3.0 million and will be recognized over a weighted average period of 
approximately one year.

At December 31, 2024, total compensation costs related to non-vested awards not yet recognized amounts to $3.7 million and 
will be recognized over a weighted average period of approximately two years. 
Employee Stock Purchase Plan
In addition to the stock options and RSUs discussed above, the Company has established the Employee Stock Purchase Plan to 
encourage employees to invest in the Company. The plan provides employees the opportunity to invest up to the IRS annual 
maximum of approximately $25,000 in the Company’s common stock at a price equal to 85% of the fair market value of the 
Company’s common stock, determined each October 1. Employees are allowed to enroll annually. Employees indicate the 
aggregate value of shares they wish to obtain through the program and their intention to pay for the shares through payroll 
deductions over the annual cycle of October 1 through September 30. Employees can withdraw anytime during the annual 
cycle, and all money withheld from the employees’ pay is returned. If an employee remains enrolled in the program, enough 
money will have been withheld from the employees’ pay during the year to pay for all the shares that the employee opted for 
under the program. At December 31, 2024, employees had subscribed to purchase 185,326 shares at $16.60 per share. The 
weighted average fair value of the options was approximately $5.02, $4.94 and $2.39 for options granted during the year ended 
December 31, 2024, 2023 and 2022, respectively.

NOTE 17 — FAIR VALUE
On a Recurring Basis:
A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant 
to the fair value measurement. There were no financial assets or liabilities carried at fair value measured on a recurring basis at 
December 31, 2024 or 2023.
On a Non-recurring Basis:
Long-lived assets are evaluated for recoverability whenever adverse effects or changes in circumstances indicate that the 
carrying value may not be recoverable. The recoverability test consists of comparing the undiscounted projected cash flows of 
the asset or asset group (which are Level 3 inputs) with the asset of asset group’s carrying amount. Should the carrying amount 
exceed undiscounted projected cash flows, an impairment loss would be recognized to the extent the carrying amount exceeds 
fair value. There were no impairment charges related to long-lived assets in 2024, 2023 or 2022 and no long-lived assets are 
required to be measured at fair value for purposes of the long-lived asset recoverability test. 
70

Due to their short-term nature, the carrying value of cash and equivalents, restricted cash, accounts receivable and accounts 
payable approximate fair value. The carrying value of the Company’s variable rate long-term debt instruments also 
approximates fair value due to the variable rate feature of these instruments. Refer to Note 8, Long-Term Debt, for additional 
information relating to the fair value of the Company's outstanding fixed-rate Convertible Notes.

NOTE 19 — LEGAL PROCEEDINGS
Lufthansa
On December 29, 2010, Lufthansa Technik AG (“Lufthansa”) filed a Statement of Claim in the Regional State Court of 
Mannheim, Germany. Lufthansa’s claim asserted that a subsidiary of the Company, AES, sold, marketed, and brought into use 
in Germany a power supply system that infringes upon a German patent held by Lufthansa. Lufthansa sought an order requiring 
AES to stop selling and marketing the allegedly infringing power supply system, a recall of allegedly infringing products sold 
to commercial customers in Germany since November 26, 2003, and compensation for damages related to direct sales of the 
allegedly infringing power supply system in Germany (referred to as “direct sales”).
AES modified the outlet units at the end of 2014 and the overwhelming majority of the modified outlet units sold from 2015 do 
not infringe the patent of Lufthansa.
In February 2015, the Regional State Court of Mannheim, Germany held that the patent was infringed. The judgment did not 
require AES to recall products that are already installed in aircraft or had been sold to other end users. 
The Company appealed to the Higher Regional Court of Karlsruhe. On November 15, 2016, the Higher Regional Court of 
Karlsruhe upheld the lower court’s decision. The Company sought permission to appeal to the German Federal Supreme Court. 
By judgment of March 26, 2019, the German Federal Supreme Court dismissed AES's appeal. With this decision, the above-
mentioned proceedings are complete.
In July 2017, Lufthansa filed an action in the Regional State Court of Mannheim for payment of damages caused by AES’s 
direct sales of the product into Germany. A first instance decision in this matter was handed down on December 6, 2019. 
According to this ruling, Lufthansa was awarded damages in the amount of approximately $3.2 million plus interest. In 2020, 
AES made payment of $4.7 million, inclusive of interest, in satisfaction of the first instance judgment. On July 12, 2023, the 
Higher Regional Court of Karlsruhe in Germany reduced the Company’s liability for direct damages on appeal from 
approximately $3.2 million plus interest to approximately $2.8 million plus interest. Additionally, in its judgment, the Court 
reduced the interest rate on damages from 5% (as held by the Regional Court of Mannheim) to 4%. Accordingly, the Company 
reclaimed overpaid damages and interest from LHT in the amount of approximately $1.2 million. This was recorded as an 
offset to Selling, General and Administrative expenses in the third quarter of 2023, upon receipt of the refund. 
Both Lufthansa and AES have filed requests with the German Federal Supreme Court to be granted leave to file appeals against 
this decision. 
On December 29, 2017, Lufthansa filed another infringement action against AES in the Regional State Court of Mannheim 
claiming that sales by AES to its international customers have infringed Lufthansa's patent if AES's customers later shipped the 
products to Germany (referred to as “indirect sales”). This action, therefore, addresses sales other than those covered by the 
action filed on December 29, 2010, discussed above. No amount of claimed damages has been specified by Lufthansa.
71

A first instance decision in this matter was issued on December 6, 2019. The Court found that indirect sales (as defined above) 
by AES to international customers infringe the patent under the conditions specified in the judgment and that the sale of 
components of the EmPower system to Germany constitutes an indirect patent infringement. The Court rejected Lufthansa's 
claim that AES is also liable for damages for the sale of modified products. This means that AES is not liable for damages 
based on the sale of modified outlet units that removed the infringing feature. AES and Lufthansa both appealed this decision. 
On July 12, 2023, the Higher Regional Court of Karlsruhe essentially upheld the first instance ruling. 
According to the Higher Regional Court of Karlsruhe ruling, AES is responsible for payment of damages for indirect sales of 
patent-infringing EmPower in-seat power supply systems in the period from December 29, 2007 to May 22, 2018. However, 
because the outlet units were modified at the end of 2014, the period for which AES is liable for damages in connection with 
indirect sales into Germany substantially finished at the end of 2014.
Both Lufthansa and AES have filed requests with the German Federal Supreme Court to be granted leave to file appeals against 
this decision.
After the accounting, Lufthansa is expected to enforce its claim for damages in separate court proceedings. These proceedings 
would most likely be tried before the Mannheim Court again, which makes it probable that the Mannheim Court will determine 
the damages for the indirect sales based on the same principles as in the direct sales proceedings (unless the latter ruling of the 
Mannheim Court is reversed on appeal). Based on the information available and the determination of the damages in the direct 
sales claim discussed above, we estimated that the Company’s total exposure related to these matters that was probable and that 
could be reasonably estimated at December 31, 2024, was approximately $11.6 million plus accrued interest. Accrued interest 
on the indirect damages reserve was estimated using the same interest rate as the direct damages. Approximately $0.7 million, 
$0.7 million, and $0.6 million was recorded within Selling, General and Administrative Expenses in the Company’s 
Consolidated Statements of Operations for each of 2024, 2023 and 2022, respectively, for additional interest accrued during 
such periods.
In connection with the indirect sales claims, we currently believe it is unlikely that the appeals process will be completed and 
any damages and related interest will be paid before December 31, 2025. Therefore, the liability related to this matter (inclusive 
of accrued interest), totaling $17.1 million, is classified within other liabilities (non-current) in the Consolidated Balance Sheets 
at December 31, 2024 and 2023. This amount may be adjusted depending on the decision of the Court on the direct sales 
damages appeal referred to previously.
In December 2017, Lufthansa filed patent infringement cases in the United Kingdom (“UK”) and in France. The Lufthansa 
patent expired in May 2018. In those cases, Lufthansa accuses AES and certain of its customers of having manufactured, used, 
sold and offered for sale a power supply system, and offered and supplied parts for a power supply system that infringed upon a 
Lufthansa patent in those respective countries. In the normal course of its supply arrangements, AES has indemnified its 
customers from liability arising from such matters, and as such will bear responsibility for any monetary damages arising from 
such claims.
On December 4, 2020, the Court held the French patent invalid for all asserted claims. There can consequently be no finding of 
infringement on first instance. Lufthansa has appealed this judgment. The appeal hearing took place on December 8, 2022, and 
on February 24, 2023, the Court upheld the first instance judgment in favor of AES. Lufthansa lodged an appeal before the 
French Supreme Court; the French Supreme Court will review the Court of Appeal of Paris’ reasoning around the nullification 
of one of the claims of the patent. AES filed briefs with the French Supreme Court on January 22, 2024 and on September 11, 
2024 in response to Lufthansa’s appeal. The written phase of the procedure was closed in January 2025 and a decision from this 
Court is currently expected in March 2025. As loss exposure is not probable and estimable at this time, the Company has not 
recorded any liability with respect to the French matter as of December 31, 2024 or December 31, 2023.
In the UK matter, the Court held the UK patent valid and 3 out of 4 asserted claims infringed in June 2020. In contrast to the 
decisions in Germany, the UK Court found that the modified components infringed a valid claim of the patent, and accordingly, 
the period for which AES or its customers would be liable in connection with direct sales into the UK extends until the 
expiration of the patent in May 2018. While AES appealed the ruling, the Court dismissed the appeal on all grounds. Lufthansa 
sought an account of the profits that AES and certain of its customers had made from UK sales. The trial of that issue took 
place in October 2024. Both the Company and Lufthansa submitted to the UK High Court of Justice calculations of the 
estimated profits derived from the reports of the parties’ respective financial experts.
The account of profits trial judgment was published on February 21, 2025. The February 2025 judgment quantified the amount 
payable in aggregate in respect of the profits derived from infringing Lufthansa’s UK patent by the defendants as $11.9 million. 
Any additional amounts required to be paid by the Company related to certain other factors peripheral to the damages award, 
including potential reimbursement of legal fees related to the damages proceedings, will be determined at follow-up hearings 
72

expected to occur in the first half of 2025. The Company is unable to estimate a range of exposure, if any, related to such 
peripheral issues, and as such, has not recorded any additional liabilities at this time
It is expected that one or more of the parties may seek permission to appeal the February 21, 2025 judgment; permission to 
appeal is not assured under English law. The Company expects that payment of the ordered liability will be required in the 
second quarter of 2025, and that an appeal, if any, would likely be heard in early 2026. 
Accordingly, the Company recorded additional expense of $4.8 million in the quarter ended December 31, 2024, within Selling, 
General and Administrative Expenses in the Company’s Consolidated Statements of Operations. The $11.9 million liability 
related to this matter is classified within Accrued Expenses and Other Current Liabilities in the accompanying Consolidated 
Balance Sheets as of December 31, 2024. The liability related to this matter was $7.4 million as of December 31, 2023, 
classified within Other Liabilities (non-current) in the Company’s Consolidated Balance Sheet at such date.
Separate from payment of profits from the February 2025 judgment discussed above, as a result of the first instance judgement 
in their favor, Lufthansa was entitled to reimbursement from AES of a proportion of its legal expenditures in the UK case. An 
interim reimbursement was paid to Lufthansa in August 2020. As a result of the appeal decision, Lufthansa will be entitled to 
reimbursement from AES of a larger proportion of its first instance legal expenditures, as well as a portion of its legal 
expenditures associated with the appeal. A liability for reimbursement of Lufthansa’s legal expenses associated with the UK 
matter for the June 2022 trial and the appeal of that decision was approximately $1.0 million and $0.7 million on December 31, 
2024 and December 31, 2023, respectively, which is expected to be paid within the next twelve months and, as such, is 
classified in Accrued Expenses and Other Current Liabilities in the accompanying Consolidated Condensed Balance Sheet as of 
December 31, 2024 and December 31, 2023. In the normal course, a defendant in the Company’s position would be ordered to 
make a partial reimbursement of Lufthansa’s legal costs. Whether that is the case and the amount depends on a number of 
variables including the size of the order for payment of profits. Additional amounts may be payable by the Company associated 
with Lufthansa’s legal fees incurred related to the account of profits proceedings, but the Company is unable to estimate a range 
of exposure and as such has not recorded any additional liabilities at this time.
Each of the German, France and UK claims are separate and distinct. Validity and infringement of the Lufthansa patent in each 
country is a matter for the courts in each of these countries, whose laws differ from each other. In addition, the principles of 
calculating damages in each jurisdiction differ substantially. Therefore, the Company has assessed each matter separately and 
cannot apply the same calculation methodology as in the German direct and indirect matters. However, it is reasonably possible 
that additional damages and interest could be incurred if the appellate court in France was to rule in favor of Lufthansa, or if 
damages in the UK matter are calculated on a different basis than our estimate or using information not currently available.
There were no other significant developments in any of these matters during the year ended December 31, 2024.
Other
On March 23, 2020, Teradyne, Inc. filed a complaint against the Company and its subsidiary, Astronics Test Systems (“ATS”) 
(together, “the Defendants”) in the United States District Court for the Central District of California alleging patent and 
copyright infringement, and certain other related claims. The Defendants moved to dismiss certain claims from the case. On 
November 6, 2020, the Court dismissed the Company from the case, and also dismissed a number of claims, though the patent 
and copyright infringement claims remained. The case proceeded to discovery. In addition, on December 21, 2020, ATS filed a 
petition for inter partes review (“IPR”) with the US Patent Trial and Appeal Board (“PTAB”), seeking to invalidate the subject 
patent, and on July 21, 2021, the PTAB instituted IPR. The PTAB issued its decision on July 20, 2022, in which it invalidated 
all of Teradyne’s patent claims. Teradyne did not appeal the decision. On June 5, 2023, the parties attended a court-ordered 
mediation but did not reach a settlement. After the mediation, Teradyne agreed to drop its remaining state law claims in 
exchange for ATS dropping one of its defenses, leaving only its copyright claim. On December 7, 2023, the District Court 
granted ATS’s motion for summary judgment on its affirmative defense of fair use. The Court subsequently entered final 
judgment in favor of ATS on December 14, 2023. Teradyne appealed to the United States Court of Appeals for the Ninth 
Circuit. On January 30, 2025, the Ninth Circuit affirmed the District Court’s grant of summary judgment. Teradyne may pursue 
an appeal by petitioning the United States Supreme Court for a writ of certiorari. It is unknown at this time whether Teradyne 
will pursue either option, or, if it does, whether the United States Supreme Court will grant a writ of certiorari. No amounts 
have been accrued for this matter in the December 31, 2024 or 2023 financial statements, as loss exposure was neither probable 
nor estimable at such times.
Other than these proceedings, we are not party to any significant pending legal proceedings that management believes will 
result in a material adverse effect on our financial condition or results of operations. Accrued legal fees were $6.5 million and 
$7.9 million as of December 31, 2024 and 2023, respectively.

NOTE 20 — SEGMENTS
The Company reports segment information based on the management approach, which designates the internal reporting used by 
the Chief Operating Decision Maker (“CODM”) for making decisions and assessing performance as the source of the 
Company’s reportable segments. The CODM, which is the Company’s Chief Executive Officer, allocates resources and 
assesses the performance of each operating segment based on historical and potential future product sales, gross margin 
associated with those sales, and operating income (loss) before interest, taxes, and corporate expenses. The Company has 
determined its reportable segments to be Aerospace and Test Systems based on the information used by the CODM.

During the year ended December 31, 2024 and 2023, reserves associated with customer bankruptcies of $3.2 million and 
$11.1 million, respectively, negatively impacted Aerospace Operating Income. Aerospace Operating Income in the years ended 
December 31, 2024 and 2023 include compensation expense related to resumed incentive programs including bonuses, 401K 
and profit sharing contributions of $19.9 million and $6.7 million, respectively. In the year ended December 31, 2022, 
$6.0 million of the AMJP grant was recognized as an offset to the cost of products sold in the Aerospace segment.
During the year ended December 31, 2023, $5.8 million was recognized in sales related to the reversal of a deferred revenue 
liability assumed with an acquisition and associated with a customer program within our Test Systems Segment which is no 
longer expected to occur, which also benefits Test Systems’ operating loss for the year. 
Corporate expenses and other for the year ended December 31, 2023, includes income of $1.8 million associated with the 
reversal of a liability related to an equity investment, as we are no longer required to make the associated payment. This amount 
is included in Other Income, Net.

NOTE 21 — DIVESTITURE ACTIVITIES
Semiconductor Test Business
On February 13, 2019, the Company completed a divestiture of its semiconductor business within the Test Systems segment. 
The total proceeds of the divestiture included two elements of contingent earnouts. The “First Earnout” was calculated based on 
a multiple of all future sales of existing and certain future derivative products to existing and future customers in each annual 
period from 2019 through 2022. The First Earnout was capped at $35.0 million in total. The “Second Earnout” was calculated 
based on a multiple of future sales related to an existing product and program with an existing customer exceeding an annual 
threshold for each annual period from 2019 through 2022. The Second Earnout was not capped. For the Second Earnout, if the 
applicable sales in an annual period did not exceed the annual threshold, no amounts would be paid relative to such annual 
period; the sales in such annual period did not carry over to the next annual period. Due to the degree of uncertainty associated 
with estimating the future sales levels of the divested business and its underlying programs, and the lack of reliable predictive 
market information, the Company elected an accounting policy to recognize such earnout proceeds, if received, as additional 
gain on sale when such proceeds are realized or realizable. We consider the proceeds realizable when we have received 
communication from the purchaser of its calculation of the earnout and the parties reach agreement on the calculation. No 
amounts were payable to the Company under either earnout for the calendar 2019 earnout. The Company agreed to an earnout 
payment of $10.7 million for the calendar 2020 earnout, which was recorded in the fourth quarter of 2021 as Other Income and 
was paid to the Company in early January 2022. In March 2022, the Company agreed with the earnout calculation for the 
calendar 2021 earnout in the amount of $11.3 million. The Company recorded the gain and received the payment in the first 
quarter of 2022. In March 2023, the Company agreed with the final earnout calculation for the calendar 2022 earnout for 
$3.4 million. The Company recorded the gain and received the payment in the first quarter of 2023.
