**PART I**

**ITEM 1.&nbsp;&nbsp;&nbsp;&nbsp;*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 certification, aircraft structures and automated test systems.

We have principal operations in the United States ("U.S."), Canada, France and Germany, 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 continuing Ukrainian and Russian conflict.

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.

**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 2025, this segment's sales were divided 75% to the commercial transport market, 15% to the military aircraft market, 9% to the general aviation market and 1% to other markets. Most of this segment's sales are a result of contracts or purchase orders received from customers, placed 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 10.4% of sales in 2025, 10.2% of sales in 2024, and 11.0% of sales in 2023. 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.

**Acquisitions**

On June 30, 2025, the Company purchased the membership interests of Envoy Aerospace, LLC ("Envoy Aerospace"), located in Aurora, Illinois. Envoy Aerospace is an FAA Organization Designation Authorization ("ODA") services provider. Envoy Aerospace is included in our Aerospace segment. The total purchase price was approximately $8.3 million, net of cash acquired and the estimated closing adjustment. Of the purchase price, $4.5 million was paid at the closing date. Payments of $2.0 million and $1.8 million will become payable by the Company following the first and second anniversary of the closing date, respectively, based on the achievement of certain milestones.

On October 13, 2025, the Company acquired all of the issued and outstanding capital stock of Bühler Motor Aviation ("BMA"), located in Uhldingen-Mühlhofen, Germany. BMA is an established manufacturer of aircraft seat actuation systems with a broad product portfolio that includes actuators, electronics, control panels, pneumatic systems, and lighting. BMA is included in our Aerospace segment. The total purchase price was approximately $18.0 million, net of cash acquired and the estimated closing adjustment. The purchase price was paid at the closing date.

------

**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 contingent purchase consideration ("earnout"). In March 2023, the Company agreed with a final earnout calculation 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.

The Company pays interest on the unpaid principal amount outstanding under the Revolving Credit Facility at a rate equal to Term SOFR plus an applicable margin ranging from 1.25% to 2.125% determined based upon the Company's Total Net Debt Leverage Ratio (as defined in the Revolving Credit Facility agreement).

The Company repurchased 80%, or $132.0 million, of the 2030 Convertible Notes during the third quarter of 2025, and $33.0 million remains outstanding at December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **2031 Convertible Notes:** On September 15, 2025, the Company issued $225.0 million of Convertible Senior Notes due 2031 (the "2031 Convertible Notes"). The 2031 Convertible Notes do not bear interest. Proceeds from the 2031 Convertible Notes were used to repurchase a portion of the 2030 Convertible Notes and enter into capped call transactions to reduce potential dilution to the Company's common stock upon conversion of the 2031 Convertible Notes.

As of December 31, 2025, the Company was in compliance with all debt covenants under its credit facilities. For additional details regarding these financing arrangements, refer to 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.

**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 2025 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.

On January 20, 2026, the United States Supreme Court ruled that the International Emergency Economic Powers Act ("IEEPA") did not authorize the President to impose tariffs. The IEEPA tariff case has been remanded back to the Court of International Trade to address whether the lower court can issue a nationwide injunction against tariffs imposed under IEEPA. It is unknown at this time if or when refunds will be issued for IEEPA tariffs previously paid by the Company.

**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.

**Seasonality**

Our business is typically not seasonal.

**Backlog**

At December 31, 2025, our consolidated backlog was $674.5 million. At December 31, 2024, our consolidated backlog was $599.2 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.

Backlog in the Aerospace segment was $600.8 million at December 31, 2025. Backlog in the Test Systems segment was $73.7 million at December 31, 2025.

**Patents**

We have a number of patents. Our patents and patent applications relate to electroluminescence, instrument panels, cord reels and handsets. 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. During the first quarter of 2025, the Company changed its financial statement presentation of research and development costs. These costs were previously included within Cost of Products Sold and were a factor in arriving at Gross Profit. Research and development expenses, which amounted to $52.1 million in 2024 and $53.7 million in 2023 have been reclassified from Cost of Products Sold to a separate line item below Gross Profit in the accompanying Consolidated Statements of Operations. All periods presented have been revised to reflect this presentation.

**Human Capital Resources**

*Human Capital Management and Corporate Culture*

As of December 31, 2025, we employed approximately 2,700 full-time employees, of whom approximately 2,100 were employed in the United States and approximately 600 were employed outside of the United States. We have approximately 150 non-exempt production employees 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.

*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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Health and dental insurance

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Generous paid time off

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 401K, profit sharing, and bonus programs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Flexible spending accounts

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Employee stock purchase plan

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Disability and life insurance

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Commute reduction, fitness, and tuition programs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 opportunity 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.**&nbsp;&nbsp;&nbsp;&nbsp;***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.

***<u>Market Risks</u>***

**The loss of Boeing as a major customer or a significant reduction in business with this customer would reduce our sales and earnings.** In 2025, 2024, and 2023 we had a concentration of sales to Boeing representing approximately 10.4%, 10.2%, 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. Any new pandemic or other future public health crisis, and efforts to contain such public health crises, 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. The commercial aerospace market is a global duopoly where Boeing and Airbus SE ("Airbus") serve as the OEMs. Their production health is vital to our performance. Historical disruptions, such as quality control challenges and factory labor actions, have previously hindered our scalability. Future shifts in their production rates remain a primary factor in our projected results. 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 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 our 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.** Our competitors include larger, more diversified corporations and vertically integrated companies that may 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop products that are superior to our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop products that are more competitively priced than our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop methods of more efficiently and effectively providing products and services; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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. In recent years, U.S. government appropriations have been affected by larger U.S. government budgetary issues and related legislation, and the U.S. government has been unable to complete its budget process before the end of its fiscal year, resulting in both governmental shutdowns and continuing resolutions providing only enough funds for U.S. government agencies to continue operating at prior-year levels. Our business, program performance, and results of operations could be impacted by the resulting disruptions to federal government offices, workers, and operations. 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 or award of contracts or purchase orders 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 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.

***<u>Strategic Risks</u>***

**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. Increased vertical integration by our customers may reduce the demand for our solutions and increase competition in our target markets.

**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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the potential exposure to unanticipated liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the potential that expected benefits or synergies are not realized and that operating costs increase;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the risks associated with incurring additional acquisition indebtedness, including that additional indebtedness could limit our cash flow availability for operations and our flexibility;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• difficulties in integrating the operations and personnel of acquired companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the potential loss of key employees, suppliers or customers of acquired businesses; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

***<u>Operational Risks</u>***

**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 and Other Matters, 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. Recent spending by hyperscalers and others to support AI is beginning to pressure supply chains for goods used to manufacture our products. 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 political and economic instability could adversely affect our business, results of operations and financial condition.** Price inflation for labor and materials, further exacerbated by political and economic instability 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 other instances of political and economic instability, including civil unrest, acts of terrorism, war, and other armed conflict, 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 such political and economic instability 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 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, 2025, 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.

------

**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, 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.

***<u>Financial Risks</u>***

**We have incurred losses in prior fiscal years and our future profitability is not certain.** For the years ended December 31, 2024 and 2023, we incurred a net loss of $16.2 million and $26.4 million, respectively. Although we achieved net income in the year ended December 31, 2025, 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 maintain revenue or 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 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.** Our 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 a total leverage ratio requirement, a consolidated interest coverage ratio requirement and a secured net debt leverage ratio requirement. 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 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. 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. If the debt under the Revolving Credit Facility were to be accelerated, we cannot assure you that our assets would be sufficient to repay in full our debt.

**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, the Company issued $165.0 million aggregate principal amount of 5.500% Convertible Senior Notes due 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. On September 15, 2025, the Company issued $225.0 million of Convertible Senior Notes due 2031. These 2031 Convertible Notes do not bear interest and are convertible under the terms of the 2031 Convertible Notes. Proceeds from the 2031 Convertible Notes were used to repurchase $132.0 million of the 2030 Convertible Notes and enter into capped call transactions to reduce potential dilution to the Company's common stock upon conversion of the 2031 Convertible Notes.

If a fundamental change (as defined in the indentures 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 may 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 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, 2025, we had approximately $343.0 million of debt outstanding. Changes to our level of debt subsequent to December 31, 2025, could have significant consequences to our business, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A significant amount of additional debt could make us more vulnerable to changes in economic conditions or increases in prevailing interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to obtain additional financing for acquisitions, capital expenditures or for other purposes could be impaired;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may be more leveraged than some of our competitors, which may result in a competitive disadvantage.

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, 2025, goodwill and net intangible assets were approximately 8.9% and 7.8% of our total assets, respectively. We had no goodwill impairment charges during 2025, 2024 or 2023. 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 2025, 2024 or 2023.

**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 was to the cash tax liability for 2024 and 2023 (as the liability for 2022 was partially offset by certain tax credits and loss carryforwards); the impact would decline annually thereafter over the five-year amortization period to an immaterial amount in year six. On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law by the president of the United States. It includes a broad range of tax reform provisions affecting businesses, including extending and modifying certain key Tax Cuts & Jobs Act of 2017. One impact of OBBBA was that the ability to deduct research and development expenditures immediately in the year incurred was restored for tax years beginning in 2025 and the ability to deduct research and development costs that were previously capitalized prior to 2025. 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.

***<u>Legal and Compliance Risks</u>***

**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. Estimates of the Germany matters 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 or paid to date. 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. Following a consequential hearing on March 20, 2025, the amount was adjusted upwards by $0.5 million related to the resolution of a provisional item. There was a further consequential hearing on May 16, 2025 which addressed applications concerning interest on the ordered damages, permission to appeal the court's findings in these matters, as well as the issue of reimbursement of legal fees in the damages phase of the litigation. The Company was ordered to make payments of $5.7 million in relation to interest and $3.5 million for partial reimbursement of Lufthansa's legal costs. All amounts due were paid in 2025. Both the Company and Lufthansa have been granted permission to appeal the rulings by the UK High Court of Justice. The appeals are scheduled to be heard by the UK Court of Appeal in March 2026. Additional amounts may be payable by the Company based on the appeal ruling. Such amounts could be substantial.

Refer to Note 19, Legal Proceedings and Other Matters, 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 2025, 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 $67.8 million as of December 31, 2025. Approximately 29% of our consolidated sales in 2025 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 with respect to trade policies, treaties, tariffs, and taxes.

The U.S. government has made, and continues to make, significant changes in U.S. trade policy and has taken certain actions that could negatively impact U.S. trade, including imposing tariffs on certain goods imported into the United States. In retaliation, other countries have implemented, and continue to evaluate imposing, additional tariffs on a wide range of American products. 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. In addition, these developments may cause the Company's customers to reduce their operating or capital expenditure budgets or forgo expansion plans or projects, which could cause them to defer, reduce, or forgo purchases of the Company's products or services.

The uncertainty with respect to U.S. trade policy includes: (i) the possibility of further altering of the existing tariffs or penalties on products manufactured outside of the United States; (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, either directly from tariffs incurred on foreign-produced products and components we directly purchase and import into the U.S. or indirectly as a result of our suppliers passing increased tariff-related costs onto us in the form of product and component price increases, which, in either such case, could have a negative impact on our business. If we attempt to renegotiate prices with suppliers or diversify our supply chain in response to tariffs, such efforts may not yield immediate results or may be

------

ineffective. We may also consider increasing prices to customers; however, this could reduce the competitiveness of our products and adversely affect sales. If we fail to manage these dynamics successfully, our gross margins and profitability could be materially adversely affected.

We cannot predict what actions may ultimately be taken with respect to tariffs or trade relations between the United States and other countries, what products may be subject to such actions, or what actions may be taken by the other countries in retaliation. Any further deterioration in the relations between the United States and its trading partners could exacerbate these actions and lead to additional governmental intervention in global trade markets.

We also cannot predict whether, and to what extent, there may be changes to international trade agreements or whether new or additional 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 or other regional conflicts could adversely affect our business and results of operations or our business partners or customers in other countries. 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.

**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).

***<u>General Risks</u>***

**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, 2025, our closing stock price ranged from a low of $15.60 to a high of $55.71. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• quarterly variations in operating results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• variances of our quarterly results of operations from securities analyst estimates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in financial estimates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• announcements of technological innovations and new products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• news reports relating to trends in our markets or adverse happenings at our customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the cancellation of major contracts or programs with our customers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to comply with the financial and other affirmative and negative covenants included in our Revolving Credit Facility.

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, government shutdowns and geopolitical instability, each with broad market impact, and particularly on the aerospace industry, could also cause significant volatility in the market price.

**ITEM 1C.**&nbsp;&nbsp;&nbsp;&nbsp;***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 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.*"

**ITEM 6. &nbsp;&nbsp;&nbsp;&nbsp;[Reserved]**

**ITEM 7.&nbsp;&nbsp;&nbsp;&nbsp;*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, France and Germany 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. 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 costs associated with the imposition of tariffs by the United States and other countries discussed herein), 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 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, tariffs impacting OEM demand, 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 tariffs and other trade policy matters, supply chain pressures, and labor market pressures have in the past resulted in, 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.

On October 22, 2025, the Company entered into the $300 million senior secured Revolving Credit Facility. The Revolving Credit Facility replaced the Company's ABL Revolving Credit Facility which was terminated on October 22, 2025. The 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 a total leverage ratio, a consolidated interest coverage ratio, and a secured net debt leverage ratio requirement. 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.

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 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 levels and anticipated ramp-ups at Boeing and Airbus, and we continue to align our operations with their production expectations.

We are monitoring the ongoing conflict between Russia and Ukraine, as well as other geopolitical tensions and conflicts around the world, and the potential impact of related export controls, financial and economic sanctions, and other restrictions imposed by the U.S., the U.K., the European Union, and other countries. While the Russia-Ukraine conflict has not resulted in a direct material adverse impact on our business to date, the implications of both this and other global conflicts in the short-term and long-term are difficult to predict. Factors such as increased energy costs, disruptions in the availability of certain raw materials, restrictions on air travel or trade with affected regions, sanctions on companies or industries, shifts in customer stability, and broader impacts on the global economy and aviation sector could pose risks to our operations and financial performance.

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.

During 2025, the Company initiated simplification activities in the Aerospace segment, including costs related to footprint rationalization and portfolio shaping. Restructuring charges, including a reduction of inventory and impairment of other long-lived assets, were recorded as a result of these simplification initiatives. In the year ended December 31, 2025, the Company recorded $5.8 million and $0.4 million in simplification initiative charges to Cost of Products Sold and Selling, General and Administrative Expenses, respectively, in the accompanying Consolidated Statements of Operations.

On January 20, 2026, the United States Supreme Court ruled that the International Emergency Economic Powers Act ("IEEPA") did not authorize the President to impose tariffs. The IEEPA tariff case has been remanded back to the Court of International Trade to address whether the lower court can issue a nationwide injunction against tariffs imposed under IEEPA. It is unknown at this time if or when refunds will be issued for IEEPA tariffs previously paid by the Company.

**ACQUISITIONS**

On June 30, 2025, the Company purchased the membership interests of Envoy Aerospace, located in Aurora, Illinois. Envoy Aerospace is an FAA ODA services provider. Envoy Aerospace is included in our Aerospace segment. The total purchase price was approximately $8.3 million, net of cash acquired and the estimated closing adjustment.

On October 13, 2025, the Company acquired all of the issued and outstanding capital stock of BMA, located in Uhldingen-Mühlhofen, Germany. BMA is an established manufacturer of aircraft seat actuation systems with a broad product portfolio that

------

includes actuators, electronics, control panels, pneumatic systems, and lighting. BMA will be included in our Aerospace segment. The total purchase price was approximately $18.0 million, net of cash acquired and the estimated closing adjustment.

**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 contingent purchase consideration ("earnout"). In March 2023, the Company agreed with a final earnout calculation 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.

**MARKETS**

<u>Commercial Transport Market</u>

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 2025 driven by improved activity with our airline customers and recovery from negative effects on production from the quality control issues and labor workforce stoppage on the 737 MAX experienced in late 2024. Aircraft build rates improved in 2025, and are expected to continue to ramp during 2026 and 2027 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 has returned 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 $599.3 million or 69.5% of our consolidated sales in 2025.

Maintaining and growing sales to the commercial transport market will depend 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.

The satellite communications industry is experiencing significant ongoing disruption, as customers evaluate the benefits of lower-cost, low Earth orbit ("LEO") solutions, challenging the traditional geosynchronous satellite-based systems. This transition represents both a risk to portions of our existing products and an opportunity to evolve our offerings to align with the growing demand for LEO products and services.

<u>Military Aerospace Market</u>

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 13.5% of our consolidated sales and amounted to $116.3 million in 2025.

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.

<u>General Aviation Market</u>

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 products. Sales to this market totaled approximately 8.1% of our consolidated sales in 2025 and amounted to $69.8 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.

<u>Test Systems Products</u>

Sales by our Test Systems segment accounted for approximately 7.5% of our consolidated sales in 2025 and amounted to $64.8 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 military applications. Sales to the aerospace and defense market were $35.4 million in 2025. Sales to the mass transit market were $5.3 million and sales to the radio test market were $24.1 million in 2025.

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 $62.9 million and $58.1 million of goodwill as of December 31, 2025 and 2024, 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.

The Company may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for some or all of the Company's 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, the Company proceeds to a quantitative test. The Company may also elect to perform a quantitative test instead of a qualitative test for any or all of the Company's reporting units. The quantitative impairment test consists of comparing the fair value of a 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 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 the reporting unit's current business, expected developments and operational strategies. If the carrying value of 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 five reporting units with goodwill as of the first day of our fourth quarter were subject to the annual goodwill impairment test. Based on our assessments of our reporting units, we concluded that goodwill was not impaired in 2025, 2024 or 2023.

A discussion by segment can be found at "Segment Results of Operations" in this MD&A.

**CONSOLIDATED OVERVIEW OF OPERATIONS**

**2025 Compared With 2024** 

Growth in sales was driven by continued strength in demand for the Aerospace segment primarily from the Commercial Transport market. Aerospace sales increased $90.6 million, or 12.8%, which more than offset the $23.9 million decline in Test Systems sales. Consolidated sales were negatively impacted by $8.3 million from revisions of estimated costs to complete certain long-term mass transit contracts in the Test Systems segment.

Consolidated cost of products sold in 2025 was $604.0 million, compared with $575.0 million in the prior year. The increase was primarily due to higher sales volume and $10.4 million of tariff expense in 2025. Additionally, simplification initiatives in the Aerospace segment, including costs related to footprint rationalization and product portfolio shaping activities, resulted in $5.8 million in charges within cost of products sold during the year. The prior year was negatively impacted by $3.8 million in higher warranty expense related to an atypical warranty campaign and $1.7 million in reserves associated with customer

------

bankruptcies. Both periods reflect the change in presentation for R&D, which is now identified as an expense item on the income statement below gross profit.

Selling, General and Administrative expenses were $138.3 million in 2025 compared with $141.9 million in the prior year driven by a decrease of $5.6 million in litigation-related legal expenses and reserve adjustments and $1.5 million of prior-year reserves associated with customer bankruptcies, partially offset by $1.8 million in higher legal and accounting expenses related to acquisitions. R&D was $8.6 million lower reflecting the timing of projects.

The current year includes a $32.6 million loss on settlement of debt as a result of a partial repurchase of the 2030 Convertible Notes, compared to a loss on settlement of debt of $10.1 million in the prior year, which was related to the $4.5 million in call premiums on the previous term loans, which were extinguished upon issuance of the 2030 Convertible Notes, and the write-off of $5.6 million of associated deferred financing costs.

As a result of the lower outstanding borrowings and the reduced cost of debt resulting from the refinancing actions in late 2024 and in 2025, interest expense decreased $9.4 million or 42.9%.

Tax expense was $2.6 million compared with a tax expense of $8.3 million in the prior year, primarily due to a valuation allowance reversal associated with research and development costs that are expected to be expensed for tax purposes in the current year under the OBBBA, along with a $1.0 million adjustment to reverse certain federal and state deferred tax liabilities.

Consolidated net income of $0.81 per diluted share improved from a net loss of $(0.46) per diluted share in the prior year from the strength in operating profit and lower interest expense.

Bookings were up 14.4% to $924.4 million with a book-to-bill ratio of 1.07:1 in 2025. The book-to-bill ratio is calculated as total orders received during the period compared with total revenue recognized during the period. Backlog as of December 31, 2025 was $674.5 million.

**Income Taxes**

Our effective tax rates for 2025 and 2024 were 8.1% and (106.1)%, respectively. Prior to 2022, research and development costs were deducted as incurred. However, beginning with the 2022 tax year, as required by the 2017 Tax Cuts and Jobs Act, these costs were required to be capitalized for tax purposes and amortized over five years. In 2025, the One Big Beautiful Bill Act ("OBBBA") restored the ability to deduct research and development expenditures immediately in the year incurred for tax years beginning in 2025 and also provided the ability to deduct research and development costs that were previously capitalized prior to 2025. Due to our cumulative three-year pre-tax loss, a valuation allowance was applied against the deferred tax asset. In addition to state and foreign income taxes, the following items had the most significant impact on the difference between our statutory U.S. federal income tax rate (21% in 2025 and 2024) and our effective tax rate:

<u>2025:</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Removal of approximately $8.7 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Approximately $6.9 million of nondeductible items which reduced the federal net operating loss for the year. The recognition of the federal net operating loss was offset by the federal valuation allowance recognized during the year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recognition of approximately $3.4 million of 2025 U.S. R&D tax credits which were offset by the federal valuation allowance recognized during the year.

<u>2024:</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recognition of approximately $3.4 million of 2024 U.S. R&D tax credits.

**SEGMENT RESULTS OF OPERATIONS**

Operating profit, as presented below, is sales less cost of products sold and other operating expenses, excluding interest expense, other corporate expenses and other non-operating sales and expenses. Cost of products sold and other operating expenses are directly identifiable to the respective segment. Operating profit is reconciled to income (loss) before income taxes in Note 20, Segments, to the Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data, of this report.

We do not have material off-balance sheet arrangements that have or are reasonably likely to have a material future effect on our results of operations or financial condition.

**2025 Compared With 2024**

Aerospace segment sales of $797.3 million were up $90.6 million, or 12.8%. Sales in the Commercial Transport market grew $74.7 million, or 14.2%. Growth was primarily related to increased demand by airlines for cabin power, lighting and safety, seat motion and system certification products and services.

Military Aircraft sales increased $28.3 million, or 32.1%, to $116.3 million, driven by pricing initiatives and increased demand for lighting and safety products, and continued progression on the MV-75 program engineering efforts. General Aviation sales decreased $4.5 million, or 6.1%, to $69.8 million, as a result of lower airframe power sales due to timing of programs. Other sales decreased $7.8 million as the Company has wound down its non-core contract manufacturing arrangements.

Aerospace segment operating profit of $113.2 million, or 14.2%, improved over the prior year resulting from leverage gained on higher volume, favorable mix, pricing initiatives and improved production efficiencies. The year also benefitted from a $6.5 million decrease in litigation-related legal expenses and reserve adjustments related to the ongoing patent dispute previously discussed. Additional benefits include a $3.8 million decrease in warranty expenses related to an atypical warranty

------

campaign and the absence of reserves for customer bankruptcies, which were $3.2 million in the prior year. These gains were partially offset by a $6.3 million increase in costs related to simplification and restructuring initiatives during the current year.

Aerospace bookings in 2025 were $847.5 million, for a book-to-bill ratio of 1.06:1. The Aerospace segment's backlog at December 31, 2025 was $600.8 million, compared to $537.6 million at December 31, 2024.

**2025 Compared With 2024**

Test Systems segment sales were $64.8 million, down $23.9 million from 2024. The decrease was driven by lower sales on our U.S. Army and U.S. Marine Corps' radio Test programs. Additionally, segment sales were negatively impacted by $8.3 million due to revisions of estimated costs to complete certain long-term mass transit Test contracts. The revisions resulted in reduced revenue recognized in the period due to lower estimates of the percentage of work completed on the programs.

Test Systems operating loss was $7.8 million compared with operating loss of $8.5 million in 2024. Net revisions to the estimated costs to complete had a $8.8 million detrimental impact to operating income and partially offset the net savings realized from recent restructuring activities. Test Systems continues to be negatively affected by mix and under absorption of fixed costs at current volume levels.

Bookings for the Test Systems segment in 2025 were $76.8 million, for a book-to-bill ratio of 1.19:1 for the year. Backlog in the Test Systems segment was $73.7 million at December 31, 2025, compared to $61.7 million at December 31, 2024.

**2024 Compared With 2023**

For a comparison of Test Systems segment results for the years ended December 31, 2024 and 2023, 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, 2024 filed with the SEC on March 5, 2025.

**CONTRACTUAL OBLIGATIONS AND OTHER COMMITMENTS**

For further information on our contractual obligations and other commitments as of December 31, 2025 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. On October 22, 2025, the ABL Revolving Credit Facility was terminated and replaced with a cash flow-based Revolving Credit Facility with a $300.0 million limit. The scheduled maturity date for the Revolving Credit Facility is October 16, 2030. Under the terms of the Revolving Credit Facility, the Company pays interest on the unpaid principal amount outstanding under the Revolving Credit Facility at a rate equal to Term SOFR plus an applicable margin ranging from 1.25% to 2.125% determined based upon the Company's Total Net Debt Leverage Ratio. The Company pays a quarterly commitment fee under the Revolving Credit Facility on unused Revolving Commitments ranging from 0.20% to 0.35%.

------

On December 3, 2024, the Company issued $165.0 million aggregate principal amount of 2030 Convertible Notes. The 2030 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 2030 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. The Company partially repurchased $132.0 million of the 2030 Convertible Notes during the third quarter of 2025 and $33.0 million remains outstanding at December 31, 2025. The 2030 Convertible Notes can be settled in any combination of cash or shares.

On September 15, 2025, the Company issued $225.0 million of 2031 Convertible Notes. The 2031 Convertible Notes do not bear any interest and will mature on January 15, 2031, unless earlier converted, redeemed or repurchased. The initial conversion rate is 18.2243 shares of common stock per $1,000 principal amount of 2031 Convertible Notes, which represents the initial conversion price of $54.87 per share. The principal amount of the 2031 Convertible Notes will be settled by paying cash and the premium, if any, can be settled in any combination of cash or shares.

In connection with the issuance of the 2031 Convertible Notes, the Company entered into capped call transactions (the "Capped Calls") with certain financial institutions. The Capped Calls are generally expected to reduce the potential dilution to the Company's common stock upon any conversion of the 2031 Convertible Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2031 Convertible Notes, as the case may be, with such reduction and/or offset subject to a cap price of approximately $83.41 per share of the Company's common stock. The Capped Calls expire January 15, 2031.

Future interest payments over the next twelve months under the Revolving Credit Facility and the Convertible Notes of approximately $6.9 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 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 $226.1 million payable over the next twelve months.

*Supplemental Retirement Plan and Post Retirement Obligations —* Anticipated payments related to 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.

*Legal Reserves —* Refer to Note 19, Legal Proceedings and Other Matters, 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.

---

<sup>1</sup> Working capital is calculated as the difference between Current Assets and Current Liabilities.

Our cash flow from operations and available borrowing capacity under our 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 $74.8 million in 2025, as compared with $30.6 million cash provided by operating activities in 2024. Cash flow from operating activities improved compared with 2024 reflecting higher cash earnings offset by higher working capital requirements associated with increased activity. Cash provided by operating activities in 2025 included $21.6 million in payments related to the UK patent dispute and $11.6 million in net federal and state income tax payments.

Our cash flows from operations are primarily dependent on our net income 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 2025 was $53.7 million compared to $8.4 million cash used for investing activities in 2024, driven by a higher level of capital expenditures related to the ongoing facility expansion activities and acquisitions during the year.

Future requirements for property, plant and equipment ("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 credit facilities 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 $22.4 million for 2025, as compared with cash used for financing activities of $14.5 million for 2024. The Company received net proceeds under its convertible notes and revolving credit facilities of $14.2 million, offset by $26.9 million in payments for capped call transactions and $10.4 million in financing-related fees and expenses in 2025. Net proceeds of debt were $2.5 million in the prior year, offset by $16.6 million in financing-related fees, expenses and settlement costs.

Cash on hand at the end of the year was $18.2 million. Net debt was $324.8 million, compared with $156.6 million at the end of 2024.

------

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. As of December 31, 2025, we are in compliance with all covenants under each of our financing arrangements. Our financing arrangements are more fully discussed in Note 8, Long-Term Debt, to our Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data, of this report.

The Company expects its cash flow from operations will provide sufficient cash flows to fund operations, including payment of any further amounts related to the Lufthansa matters. The Company paid $21.6 million for ordered liabilities for damages, interest and legal fee reimbursement related to the UK matter in the year ended December 31, 2025. Both the Company and Lufthansa have been granted permission to appeal the rulings by the UK High Court of Justice. The appeals are scheduled to be heard by the UK Court of Appeal in March 2026. 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.

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 and Other Matters, to our Consolidated Financial Statements in Item 8, Financial Statements and Supplementary Data and Item 1A, Risk Factors, of this report.

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 million. During the year ended December 31, 2025 and 2024, the Company did not sell any shares of its common stock under the ATM Program. As of December 31, 2025, 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.

**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 at this time.

**RECENT ACCOUNTING PRONOUNCEMENTS**

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.** &nbsp;&nbsp;&nbsp;&nbsp;***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 $13.9 million at December 31, 2025. A 10% change in the value of the U.S. dollar versus the Canadian dollar would have had an immaterial impact to 2025 net income. Net assets held in or measured in Euros amounted to $52.5 million at December 31, 2025. A 10% change in the value of the U.S. dollar versus the Euros would have had an immaterial impact to 2025 net income.

Risk due to fluctuation in interest rates is a function of the Company's floating rate debt obligations, which total approximately $85.0 million as of December 31, 2025. A change of 1% in interest rates of all variable rate debt would impact annual net income by approximately $0.9 million, before income taxes.

As discussed elsewhere in this report, our business continues to face uncertainty due to various economic factors, including inflationary pressures, disruptions in the global supply chain (such as costs related to recently imposed tariffs by the United States and other countries), challenges with labor availability and associated costs, and the ongoing conflict between Russia and Ukraine and broader geopolitical tensions. The duration and scope of the Russia-Ukraine war, along with the broader economic and geopolitical uncertainties, remain unpredictable. Consequently, while we cannot reasonably estimate the ultimate financial impact on our results at this time, such impacts could be material.

**ITEM 8.**&nbsp;&nbsp;&nbsp;&nbsp;***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, 2025 and 2024, the related consolidated statements of operations, comprehensive income (loss), shareholders' equity and cash flows for each of the three years in the period ended December 31, 2025, 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, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, 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, 2025, 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 February 26, 2026 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 matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

| | ***Revenue Recognition*** |
| *Description of the Matter* | 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 at certain components 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. <br>Auditing management's evaluation of contracts with customers at certain components 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. <br>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, 2025 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, 2025.

We completed acquisitions in 2025, which were excluded from our management's report on internal control over financial reporting as of December 31, 2025. We acquired Envoy Aerospace, LLC on June 30, 2025 and Bühler Motor Aviation, on October 13, 2025. These acquisitions were included in our 2025 consolidated financial statements and constituted $22.8 million and $18.7 million of total and net assets, respectively, as of December 31, 2025 and $6.9 million and $0.5 million of sales and net income, respectively, for the year then ended.

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, 2025, 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, 2025, based on the COSO criteria.

As indicated in the accompanying Management's Report on Internal Control Over Financial Reporting, management's assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Envoy Aerospace, LLC and Bühler Motor Aviation. The Company acquired Envoy Aerospace, LLC on June 30, 2025 and Bühler Motor Aviation, on October 13, 2025. These acquisitions were included in the 2025 consolidated financial statements of the Company and constituted $22.8 million and $18.7 million of total and net assets, respectively, as of December 31, 2025 and $6.9 million and $0.5 million of sales and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Envoy Aerospace, LLC and Bühler Motor Aviation.

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, 2025 and 2024, the related consolidated statements of operations, comprehensive income (loss), shareholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) and our report dated February 26, 2026 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 certification, aircraft structures and automated test systems.

We have principal operations in the United States ("U.S."), Canada, France and Germany, 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.

See Note 21, Acquisitions, for details of our recent acquisitions.

***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 costs amounted to $43.5 million in 2025. Beginning in 2025, the Company changed its financial statement presentation of research and development costs. These costs were previously included within Cost of Products Sold and were included in arriving at Gross Profit. Research and development expenses, which amounted to $52.1 million in 2024 and $53.7 million in 2023 have been reclassified from Cost of Products Sold to a separate line item below Gross Profit in the accompanying Consolidated Statements of Operations. All periods presented have been revised to reflect this presentation. Selling, General and Administrative ("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, 2025, 2024 and 2023.

***Simplification Initiatives***

During 2025, the Company initiated simplification activities in the Aerospace segment, including costs related to footprint rationalization and portfolio shaping. Restructuring charges, including a reduction of inventory and impairment of other long-lived assets, were recorded as a result of these simplification initiatives. In the year ended December 31, 2025, the Company recorded $5.8 million and $0.4 million in simplification initiative charges to Cost of Products Sold and Selling, General and Administrative Expenses, respectively, in the accompanying Consolidated Statements of Operations.

***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.

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) which was terminated on October 22, 2025, the Company had a cash dominion arrangement with the banking institution for its accounts within the United States whereby daily cash receipts were contractually utilized to pay down outstanding balances on the ABL Revolving Credit Facility. Account balances that had not yet been applied to the ABL Revolving Credit Facility were 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.

| | | |
|:---|:---|:---|
| | **December 31,** | **December 31,** |
| (In thousands) | **2025** | **2024** |
| Cash and Cash Equivalents | $18180 | $9285 |
| Restricted Cash |  | 9143 |
| Total Cash and Restricted Cash Shown in Statements of Cash Flows | $18180 | $18428 |

---

***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.

***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. These receivables 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. Inventory costs include direct materials, direct labor, and manufacturing overhead, including freight-in, custom duties, and import tariffs directly attributable to bringing the inventory to its existing location and condition. 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. Implementation costs associated with cloud computing arrangements are reflected in Cash from Operating Activities on the Consolidated Statements of Cash Flows in accordance with ASC Topic 350-40, *Intangibles - Goodwill and Other - Internal-Use Software*. The Company capitalized $2.8 million related to such arrangements within other non-current assets in the Consolidated Balance Sheets as of December 31, 2025. Costs capitalized were insignificant as of December 31, 2024. Amortization expense was insignificant in 2025, 2024 and 2023.

***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 $10.2 million, $11.5 million and $12.2 million in 2025, 2024 and 2023, 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, loss on debt settlement or a reduction to equity based on the nature of the debt instrument.

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 2025, 2024 and 2023 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 below their estimated fair values. Impairment is tested under ASC Topic 350, *Intangibles - Goodwill and Other,* as amended by ASU 2012-2.

The 2025, 2024 and 2023 assessments indicated no impairment to the intangible assets of the Company 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 Company estimates the fair value of the convertible notes based on quoted prices for these instruments in active markets, classified as Level 1 measurements within the fair value hierarchy. The fair value of the 2030 Convertible Notes was approximately $84.8 million and $176.9 million as of December 31, 2025 and 2024, respectively. The fair value of the 2031 Convertible Notes was approximately $264.1 million as of December 31, 2025.

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.

***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 $74.5 million, $78.7 million, and $65.6 million during the years ended December 31, 2025, 2024 and 2023, respectively, for the portion of deferred tax assets 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 2025, 2024 and 2023.

***Dividends***

The Company has not paid any cash dividends in the three-year period ended December 31, 2025.

***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, 2025 and 2024, 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 off. The Company has capitalized $6.0 million and $8.3 million of costs as of December 31, 2025 and 2024, respectively. Amortization of fulfillment costs recognized within Cost of Products Sold was $3.5 million and $3.1 million in 2025 and 2024, respectively. No amortization of fulfillment costs was recorded in 2023.

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.

In contracts with multiple performance obligations, the contract's transaction price is allocated to each performance obligation based on the estimated standalone selling price of each distinct good or service in the contract. In these cases, the Company uses an expected cost plus margin approach to determine the standalone selling price for each performance obligation. Shipping and handling activities that occur after the customer has obtained control of the good are considered fulfillment activities, not performance obligations.

Contract modifications are routine in the performance of our contracts, and contracts may be 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. From time to time, contracts may contain variable consideration, which could include incremental fees or penalty provisions related with performance. In these situations, variable consideration is included in the estimated transaction price based on an assessment of all information (i.e., historical, current and forecasted) that is reasonably available to the Company 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 costs 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, 2025, we had $674.5 million of remaining performance obligations, which we refer to as total backlog. We expect to recognize approximately $533.1 million of our remaining performance obligations as revenue in 2026.

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 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.

------

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:

---

| | | |
|:---|:---|:---|
| (In thousands) | **Contract Assets** | **Contract Liabilities** |
| Beginning Balance, January 1, 2025 | $54171 | $28171 |
| Ending Balance, December 31, 2025 | $54687 | $26962 |

---

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 $8.3 million in revisions of estimated costs to complete certain long-term mass transit Test contracts which were recorded in 2025. The revisions resulted in reduced revenue recognized during 2025 due to lower estimates of the percentage of work completed on the programs. The decrease in contract liabilities reflects the net impact of revenue recognized in excess of new customer advances or deferred revenues recorded.

We recognized $20.8 million and $16.8 million during the year ended December 31, 2025 and 2024, respectively, in revenues that were included in the contract liability balance at the beginning of the period.

Based on our 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 2025, 2024 and 2023.

**NOTE 8 — LONG-TERM DEBT**

The Company entered into a $90.0 million term loan facility on January 19, 2023, and paid interest at a rate equal to SOFR (which was required to be at least 2.50%) plus 8.75%. The Company refinanced its credit facilities on July 11, 2024, and repaid in full all outstanding indebtedness under the previous term loan dated January 19, 2023.

------

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 amounts borrowed thereunder carrying an interest rate of SOFR plus between 2.50% to 3.00%. Borrowings were 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 ("Term Loan Facility") on July 11, 2024 at an interest rate of SOFR plus between 5.50% to 6.75%.

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 could 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 was 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 was permitted to incur under the ABL Revolving Credit Facility, subject to completion of the 2030 Convertible Notes offering (discussed below).

Under the terms of the ABL Revolving Credit Facility, the Company paid 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 was 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.

Pursuant to the ABL Revolving Credit Facility, the Company was subject to a minimum fixed charge coverage ratio of 1.10 to 1.00. The Company was also required to maintain a minimum excess availability of the greater of 10% of the borrowing base under the ABL Revolving Credit Facility, or $15.0 million. 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.

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 2030 Convertible Notes (discussed below).

On October 22, 2025, the Company entered into a $300.0 million senior secured, cash flow-based revolving credit facility (the "Revolving Credit Facility"). The Revolving Credit Facility replaced the Company's ABL Revolving Credit Facility, which was terminated on October 22, 2025. The scheduled maturity date for the Revolving Credit Facility is October 16, 2030. Under the terms of the Revolving Credit Facility, the Company pays interest on the unpaid principal amount outstanding under the Revolving Credit Facility at a rate equal to Term SOFR (as defined in the Revolving Credit Facility) plus an applicable margin ranging from 1.25% to 2.125% determined based upon the Company's Total Net Debt Leverage Ratio (as defined in the Revolving Credit Facility). The Company pays a quarterly commitment fee under the Revolving Credit Facility on unused Revolving Commitments ranging from 0.20% to 0.35% determined based upon the Company's Total Net Debt Leverage Ratio.

Pursuant to the Revolving Credit Facility, the Company is subject to a total leverage ratio covenant that requires that the Company's Total Net Debt Leverage Ratio may not exceed 4.50 to 1.00, provided that the Company's Total Net Debt Leverage Ratio for the fiscal quarter ending December 31, 2025, may not exceed 4.75 to 1.00. The Company is also subject to a consolidated interest coverage ratio covenant that requires that the Company's Consolidated Interest Coverage Ratio (as defined in the Revolving Credit Facility) may not be less than 3.50 to 1.00 and a secured net debt leverage ratio covenant that requires that the Company's Secured Net Debt Leverage Ratio (as defined in the Revolving Credit Facility) may not exceed 3.00 to 1.00. As of December 31, 2025, the Company was in compliance with these covenants. On December 31, 2025, there was $85.0 million outstanding on the Revolving Credit Facility and there remained $212.8 million available for future borrowings, net of outstanding letters of credit. The Revolving Credit Facility has an accordion feature, which allows the Company to request incremental commitments of up to $100.0 million plus additional incremental amounts so long as maximum leverage requirements are met.

***2030 Convertible Notes***

On December 3, 2024, the Company issued $165.0 million aggregate principal amount of 5.500% Convertible Senior Notes due 2030 (the "2030 Convertible Notes"). The 2030 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 2030 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 2030 Convertible Notes, which represent the initial conversion price of $22.89

------

per share. The 2030 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 2030 Convertible Notes may be called at the option of the issuer. Under the same conditions, the Company can elect to redeem the 2030 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 2030 Convertible Notes may be called at the option of the holder. During the fiscal quarter ended December 31, 2025, our stock price met the price trigger defined above, and therefore, holders of our 2030 Convertible Notes have the ability to convert their notes at their option at any time during the fiscal quarter ended April 4, 2026.

***2031 Convertible Notes***

On September 15, 2025, the Company issued $225.0 million aggregate principal amount of Convertible Senior Notes due 2031 (the "2031 Convertible Notes") for net proceeds of $216.7 million. The Company used part of the net proceeds to repurchase a portion of the 2030 Convertible Notes and the remainder to enter into the capped call transactions, as further described below. The 2031 Convertible Notes do not bear any interest and will mature on January 15, 2031, unless earlier converted, redeemed or repurchased. The initial conversion rate is 18.2243 shares of common stock per $1,000 principal amount of 2031 Convertible Notes, which represents the initial conversion price of $54.87 per share. The 2031 Convertible Notes are convertible at the option of the holders at any time on or after October 15, 2030, 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 cash up to the aggregate principal amount of the 2031 Convertible Notes to be converted and 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, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the Notes being converted. Beginning January 22, 2029, if the Company's stock price has been at least 130% of the conversion price for a specified period of time, the 2031 Convertible Notes may be called at the option of the issuer. After the fourth quarter of 2025, if the Company's stock price has been at least 130% of the conversion price for 5 of the first 20 trading days of such fiscal quarter, the 2031 Convertible Notes may be redeemed at the option of the holder during the 30-trading day period beginning on, and including, the 21st trading day of such quarter. As of December 31, 2025, the 2031 Convertible Notes were not redeemable.

***Partial Repurchase of 2030 Convertible Notes***

The Company used approximately $189.8 million of the net proceeds from the issuance of the 2031 Convertible Notes, together with approximately $85.0 million of borrowings under its ABL Revolving Credit Facility and approximately $11.0 million of cash on hand, to repurchase approximately $132.0 million in aggregate principal amount of outstanding 2030 Convertible Notes pursuant to privately negotiated exchange agreements entered into with certain holders of the 2030 Convertible Notes. The total cash paid in connection with this repurchase was approximately $285.8 million. The repurchase was accounted for in accordance with ASU 2024-04, *Debt – Debt with Conversion and Other Options (Subtopic 470-20)* and resulted in the recognition of an inducement charge of $32.6 million within Loss on Settlement of Debt in the Consolidated Statements of Operations. The Company also recorded a reduction to equity of $125.5 million, inclusive of a reduction to unamortized debt issuance costs of $4.3 million.

Interest expense was $12.6 million, $22.0 million and $23.3 million for 2025, 2024 and 2023, respectively.

The Company recorded non-cash write-offs of deferred financing costs related to exiting ABL lenders of approximately $0.6 million and $0.5 million in years ending December 31, 2025 and 2024, respectively, in Interest Expense within the Consolidated Statements of Operations. In 2024, the Company recorded a Loss on Settlement of Debt of approximately $10.1 million, 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.

Debt issuance cost amortization expense was $2.5 million, $2.6 million and $3.0 million for 2025, 2024 and 2023, respectively. All costs are amortized to interest expense over the term of the respective agreement. Unamortized deferred debt issuance costs associated with the Revolving Credit Facility ($3.0 million as of December 31, 2025) and ABL Revolving Credit Facility ($3.0 million as of December 31, 2024) were recorded within Other Assets.

------

The following table presents the outstanding principal amount and carrying value of the Convertible Notes as of the dates indicated:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| | December 31, 2025 | December 31, 2025 | December 31, 2025 | December 31, 2024 | December 31, 2024 | December 31, 2024 |
| (In thousands) | Principal | Unamortized Debt Issuance Costs | Carrying Value | Principal | Unamortized Debt Issuance Costs | Carrying Value |
| 2030 Convertible Notes | $33000 | $(1023) | $31977 | $165000 | $(6331) | $158669 |
| 2031 Convertible Notes | 225000 | (7526) | 217474 |  |  |  |
| &nbsp;&nbsp;Total | $258000 | $(8549) | $249451 | $165000 | $(6331) | $158669 |

---

The Company estimates the fair value of the convertible notes based on quoted prices for these instruments in active markets, classified as Level 1 measurements within the fair value hierarchy. The fair value of the 2031 Convertible Notes was approximately $264.1 million as of December 31, 2025. The fair value of the 2030 Convertible Notes was approximately $84.8 million and $176.9 million as of December 31, 2025 and December 31, 2024, respectively.

***Capped Call Transactions***

In connection with the issuance of the 2031 Convertible Notes, the Company entered into capped call transactions (the "Capped Calls") with certain financial institutions. The Capped Calls are generally expected to reduce the potential dilution to the Company's common stock upon any conversion of the 2031 Convertible Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2031 Convertible Notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the Capped Calls is initially approximately $83.41 per share of the Company's common stock and is subject to certain adjustments under the terms of the capped call transactions. The Capped Calls expire January 15, 2031.

We used approximately $26.9 million of the net proceeds from the 2031 Convertible Notes to purchase the Capped Calls. These instruments are classified as equity and recorded as a reduction of additional paid-in capital in the Consolidated Statements of Changes in Stockholders' Equity.

**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:

---

| | | | |
|:---|:---|:---|:---|
| (In thousands) | **2025** | **2024** | **2023** |
| Balance at Beginning of the Year | $18081 | $9751 | $8009 |
| Warranty Liabilities Acquired | 995 |  |  |
| Warranties Issued | 5404 | 12078 | 6260 |
| Reassessed Warranty Exposure | 2066 | 11 | (397) |
| Warranties Settled | (5806) | (3759) | (4121) |
| Balance at End of the Year | $20740 | $18081 | $9751 |

---

Warranties issued includes an atypical warranty reserve for a new product launch that requires field modification that resulted in $1.4 million and $5.2 million in expense during 2025 and 2024, respectively.

**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. The right-of-use ("ROU") assets, ROU lease liabilities, and lease costs related to the Company's finance leases were immaterial as of December 31, 2025 and December 31, 2024.

------

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 ROU assets are based on the present value of the remaining minimum rental payments. The Company's operating lease liability increased approximately $15.3 million as a result of acquiring ROU assets from new leases entered into during the year ended December 31, 2025. In determining the incremental borrowing rate, we have considered borrowing data for secured debt obtained from our lending institution.

The following is a summary of the Company's operating ROU assets and lease liabilities at December 31:

During the year ended December 31, 2025, the Company had positive operating cash flow for operating leases due to the receipt of $8.1 million tenant improvement allowances. As permitted by ASC 842, leases with expected durations of less than 12 months from inception (i.e. short-term leases) were excluded from the Company's calculation of its lease liability and ROU asset.

The weighted-average remaining term for the Company's operating leases is approximately 7 years. The weighted-average discount rate for the Company's operating leases is approximately 6.4%.

**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 $74.5 million, $78.7 million, and $65.6 million during the years ended December 31, 2025, 2024 and 2023, respectively, for the portion of deferred tax assets not realizable by the Company's existing deferred tax liabilities.

During the year ended December 31, 2025, the company recorded a deferred tax asset of approximately $6.3 million as an increase to additional paid-in capital with an offsetting valuation allowance of approximately $6.3 million as a decrease to additional paid-in capital. Any subsequently recognized tax benefits associated with this $6.3 million valuation allowance are expected to be credited directly to contributed capital.

During the year ended December 31, 2025, the Company reversed approximately $1.4 million of valuation allowances against certain foreign deferred tax assets as a result of no longer having cumulative pre-tax losses in the respective foreign jurisdictions during the three-year period ending with the current year.

On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law in the United States. The OBBBA permanently extends and modifies significant provisions enacted in 2017 as part of the Tax Cuts and Jobs Act ("TCJA") that were originally set to expire at the end of 2025. In addition, the OBBBA makes changes to certain U.S. corporate tax provisions, many of which are not in effect until 2026. Key provisions of the Tax Act relevant to the Company's operations include immediate expensing of certain domestic research and development expenses and domestic capital expenditures beginning in 2025 as well as changes to various U.S. international tax provisions going forward. The Company anticipates it will elect to deduct the remaining previously capitalized domestic research and development costs equally between 2025 and 2026 and expense domestic research and development costs as incurred for the 2025 tax year. As a result of this provision of the OBBBA, deferred tax assets related to capitalized research expenses decreased by approximately $16.3 million during the year ended December 31, 2025. The Company maintains a full valuation allowance against this deferred tax asset.

At December 31, 2025, gross federal net operating losses amounted to approximately $41.8 million, of which, $1.1 million 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 remaining $40.7 million of federal net operating losses, which are not subject to Internal Revenue Code Section 382 will carryforward indefinitely. The Company maintains a full valuation allowance against this deferred tax asset.

At December 31, 2025, gross state net operating loss carryforwards amounted to approximately $146.5 million. Of these state net operating loss carryforwards, $127.3 million begin to expire at various dates from 2025 through 2045 and the remaining $19.2 million will carryforward indefinitely. The Company maintains a full valuation allowance against this deferred tax asset.

At December 31, 2025, federal income tax credit carryforwards amounted to approximately $3.4 million and will expire in 2045. State income tax credit carryforwards amounted to approximately $1.4 million and begin to expire at various dates from 2025 to 2044. 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, 2025, 2024, or 2023, nor are any material penalties or interest costs included in expense for each of the years ended December 31, 2025, 2024 and 2023. 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, 2020, and 2022 through 2024 for federal purposes and 2021 through 2024 for state purposes.

Pretax income from the Company's foreign subsidiaries amounted to approximately $9.0 million, $9.6 million and $6.5 million for 2025, 2024 and 2023, 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, 2025, 2024 and 2023, we determined that we could no longer assert indefinite reinvestment on approximately $7.0 million, $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 $0.3 million, $0.2 million, and $0.1 million at December 31, 2025, 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 $17.3 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, 2025, 2024, and 2023.

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.

Total charges to income before income taxes for this plan was approximately $9.6 million, $8.9 million and $5.3 million in 2025, 2024 and 2023, respectively. The Company had funded the contributions in 2023 and the first quarter of 2024 with treasury stock in lieu of cash and funded the remainder of the 2024 contribution and the 2025 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, 2025 and 2024 amounts to $24.5 million and $21.4 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, 2025 or 2024 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 service of active participants.

Unrecognized prior service gains of $0.1 million and unrecognized actuarial gains of $0.9 million are included in AOCI at December 31, 2025 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 thousands) | **2025** | **2024** |
| Funded Status |  |  |
| Projected Benefit Obligation |  |  |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest Cost | 1306 | 1371 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Actuarial Loss (Gain) | 2587 | (6134) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Special Termination Benefits |  | 624 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Benefits Paid | (650) | (348) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;End of the Year — December 31 | $27554 | $24311 |

---

In 2025, the net actuarial loss of $2.6 million is due to the decrease of 11 basis points in the discount rate and change in the bonus scale used to measure the benefit obligation as of December 31, 2025 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:

---

| | | |
|:---|:---|:---|
| | **2025** | **2024** |
| Discount Rate | 5.37% | 5.48% |
| Future Average Compensation Increases | 3.50% | 3.00% |

---

The plans are unfunded at December 31, 2025 and are recognized in the accompanying Consolidated Balance Sheets as a current accrued pension liability of $1.1 million and a long-term accrued pension liability of $26.5 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.

The following table summarizes the components of the net periodic cost for the years ended December 31:

| Discount Rate | 5.48% | 4.79% | 5.00% |
| Future Average Compensation Increases | 3.00% | 3.00% | 2.00% - 3.00% |

---

Benefit payments expected in each of the next five years are as follows: 2026 - $1.1 million, 2027 - $1.0 million, 2028 - $2.2 million, 2029 - $2.2 million, and 2030 - $2.2 million. Benefits expected to be paid in the aggregate between 2031 and 2035 are $10.3 million.

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 95.5% funded as of January 1, 2025. The Company's contributions to the plan were $0.8 million in 2025, $0.9 million in 2024 and $0.7 million in 2023. 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 2025 or 2024. As of December 31, 2025, 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, 2025, approximately 7.1 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.

***Comprehensive Income (Loss) and Accumulated Other Comprehensive Loss***

Comprehensive income or loss consists of net income or loss and the after-tax impact of retirement liability adjustments. No income tax effect is recorded for currency translation adjustments.

---

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 2030 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 excluded all impacts of the 2030 Convertible Notes from the computation of diluted earnings per share as the effect would be anti-dilutive. The Company will settle the principal amount of the 2031 Convertible Notes by paying cash and settle the premium in any combination of cash or shares. The Company's average stock price during the period outstanding was below the conversion price for the 2031 Convertible Notes, therefore no incremental shares were included in diluted earnings per share.

------

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 incurred a net loss for the years ended December 31, 2024 and 2023, therefore all outstanding stock options and unvested restricted stock units were excluded from the computation of diluted loss per share because the effect of their inclusion would be antidilutive.

Antidilutive shares excluded from diluted earnings (loss) per share computations were as follows:

The Company funded substantially all of its 2023 and a portion of its 2024 401K contributions outstanding with treasury stock in lieu of cash, and returned to cash contributions in the second quarter of 2024. The earnings per share computations for the year ended December 31, 2023 are inclusive of approximately 0.1 million in shares outstanding for the equivalent shares needed to fulfill the period's 401K obligation using the closing share price as of December 31, 2023.

**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, 2025, the Company had options outstanding for 49,887 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, 2025, the Company had options outstanding for 23,690 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, 2025, the Company had stock options and RSUs outstanding that covered 1,889,586 shares under the Long Term Incentive Plan, and there were 689,542 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.

The following table provides compensation expense information based on the fair value of stock options and RSUs for the years ended December 31 as follows:

---

| | | | |
|:---|:---|:---|:---|
| (In thousands) | **2025** | **2024** | **2023** |

| Tax Benefit | (1221) | (1564) | (1259) |
| Equity-based Compensation Expense, Net of Tax | $5578 | $7006 | $5939 |

---

Tax benefit excludes the impact of valuation allowances recorded against deferred tax assets. In the fourth quarter of 2024, the Company entered into a Transition and Retirement Agreement with its former CFO, which granted certain benefits related to the retirement. Equity-based Compensation Expense in 2024 includes $0.6 million related with accelerated RSU vesting pursuant to that Agreement.

| | **2025** | **2024** | **2023** |
| Weighted Average Fair Value of the Options Granted | $31.97 | $10.55 | $8.39 |

The weighted average fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following assumptions:

---

| | | | |
|:---|:---|:---|:---|
| | **2025** | **2024** | **2023** |

| Dividend Yield | —% | —% | —% |
| Volatility Factor | 0.65 | 0.61 | 0.58 |
| Expected Life in Years | 6 years | 7 years | 3 - 7 years |

---

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.

A summary of the Company's stock option activity and related information for the year ended December 31 is as follows:

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 $54.24, $15.96 and $17.42 as of December 31, 2025, 2024 and 2023, respectively.

Shares withheld by the Company upon the exercise of stock options to cover exercise price and satisfy tax withholding obligations represent an increase to treasury shares outstanding.

During the year ended December 31, 2025, 186,179 options vested, with a weighted average fair value of $7.52. The total fair value of options that vested during the year amounted to $1.4 million, $2.1 million and $3.0 million for the years ended December 31, 2025, 2024 and 2023, respectively. The total intrinsic value of options exercised during the year amounted to $3.6 million for the year ended December 31, 2025. No options were exercised in the years ended December 31, 2024 or December 31, 2023. During the year ended December 31, 2025, 39,575 options were forfeited with a weighted average fair

***Restricted Stock Units***

The fair value of each RSU granted is equal to the fair market value of the Company's Common Stock on the date of grant. The RSUs granted to employees generally cliff vest three years from the date of grant, while RSUs granted to directors cliff vest six months from the date of grant.

A summary of the Company's RSU activity and related information for the year ended December 31 is as follows:

Included in total equity-based compensation expense for the year ended December 31, 2025 was $4.4 million related to RSUs. At December 31, 2025, total compensation costs related to non-vested awards not yet recognized amounts to $4.5 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, 2025, employees had subscribed to purchase 90,143 shares at $38.22 per share. The weighted average fair value of the options was approximately $12.66, $5.02 and $4.94 for options granted during the year ended December 31, 2025, 2024 and 2023, respectively.

**NOTE 17 — FAIR VALUE**

<u>On a Recurring Basis:</u>

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, 2025 or 2024.

<u>On a Non-recurring Basis:</u>

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 2025, 2024 or 2023 and no long-lived assets are required to be measured at fair value for purposes of the long-lived asset recoverability test.

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 18 — SELECTED QUARTERLY FINANCIAL INFORMATION**

The following table summarizes selected quarterly financial information for 2025 and 2024:

**NOTE 19 — LEGAL PROCEEDINGS AND OTHER MATTERS**

<u>Legal Proceedings</u>

*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.

In February 2015, the Regional State Court of Mannheim, Germany held that the patent was infringed.

The Company appealed to the Higher Regional Court of Karlsruhe. In November 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. In March 2019, the German Federal Supreme Court dismissed AES's appeal. With this decision, these proceedings are complete.

AES modified the outlet units at the end of 2014 and the overwhelming majority of the modified outlet units sold from 2015 on do not infringe the patent of Lufthansa.

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 infringing power supply system into Germany (referred to as "direct sales"). 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. In July 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 year ended December 31, 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 the direct sales covered by the action discussed above.

A first instance decision in this matter was issued in December 2019. While the Court found in favor of Lufthansa, they rejected Lufthansa's claim that AES is also liable for damages for the sale of modified products. Thus, 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. In July 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 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.

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, 2025 and 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, as were reduced on the direct damages appeal discussed above. Approximately $0.5 million, $0.7 million, and $0.7 million was recorded within Selling, General and Administrative Expenses in the Company's Consolidated Statements of Operations for each of 2025, 2024 and 2023, respectively, for additional interest accrued during such periods.

------

We believe it is unlikely that the appeals process will be completed and any indirect damages and related interest will be paid before December 31, 2026. Therefore, the liability related to this matter (inclusive of accrued interest), totaling $17.6 million and $17.1 million, is classified within other liabilities (non-current) in the Consolidated Balance Sheets at December 31, 2025 and 2024, respectively. 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 subject patent expired in May 2018. 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, and consequently there could be no finding of infringement. Lufthansa appealed this judgment. On February 24, 2023, the Court upheld the first instance judgment in favor of AES. Lufthansa lodged an appeal before the French Supreme Court. A decision from this Court was rendered on March 19, 2025, remanding the case to the Court of Appeal of Paris for reconsideration of the invalidity of the French patent. A second trial on nullity is scheduled on October 28, 2026; a ruling on nullity is not expected before early first quarter 2027. 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, 2025 or 2024.

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 damages based on 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 February 21, 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. 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 was classified within Accrued Expenses and Other Current Liabilities in the accompanying Consolidated Balance Sheets as of December 31, 2024. Following a consequential hearing on March 20, 2025, the amount was adjusted upwards by $0.5 million related to the resolution of a provisional item.

In a further consequential hearing on May 16, 2025 the Company was ordered to make payments of $5.7 million in relation to interest and $3.5 million for partial reimbursement of Lufthansa's legal costs. Both of these items are reflected within Selling, General and Administrative Expenses in the Company's Consolidated Statement of Operations for the year ended December 31, 2025.

During the year ended December 31, 2025, the Company made payments totaling $21.6 million, in satisfaction of the liabilities for damages, interest and provisional legal fee reimbursement related to the damages proceedings.

Both the Company and Lufthansa have been granted permission to appeal the rulings by the UK High Court of Justice. The appeals are scheduled to be heard by the UK Court of Appeal in March 2026.

A liability for partial reimbursement of Lufthansa's legal expenses associated with the UK matter for the first instance trial and the later appeal was approximately $1.0 million as of December 31, 2025 and 2024, 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 Sheets as of December 31, 2025 and 2024.

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 upon conclusion of the appeal are calculated on a different basis than the initial judgment.

There were no other significant developments in any of these matters during the year ended December 31, 2025.

*Other Proceedings*

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. In addition, on November 6, 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 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 has elected not to pursue an appeal. As such, the summary judgment ruling stands and final judgment in favor of ATS has been entered. This matter is concluded.

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 $2.1 million and $6.5 million as of December 31, 2025 and 2024, respectively.

<u>Other Matters</u>

On January 20, 2026, the United States Supreme Court ruled that the International Emergency Economic Powers Act ("IEEPA") did not authorize the President to impose tariffs. The IEEPA tariff case has been remanded back to the Court of International Trade to address whether the lower court can issue a nationwide injunction against tariffs imposed under IEEPA. It is unknown at this time if or when refunds will be issued for IEEPA tariffs previously paid by the Company.

**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.

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. The higher level of Aerospace capital expenditures in 2025 is related to ongoing facility expansion activities and growth and maintenance expenditures that had been previously deferred during the pandemic.
