A Message from Our CEO 
Dear Stockholders: 
In 2024, we delivered solid financial results in a dynamic environment. Demand in the 
Semiconductor and Data Center Computing markets improved, offset by inventory digestion in the 
Industrial and Medical and Telecom and Networking markets. After hitting a low point in the first 
quarter, revenue increased every quarter through year-end and returned to year-over-year growth 
in the fourth quarter. In addition, we improved our gross margins each quarter throughout the year 
as we executed our multi-year manufacturing consolidation plan. 
During the year, we made significant progress across our strategic initiatives. We accelerated new 
product introductions by launching 35 new platform products, as well as numerous custom and 
modified standard products. We invested in R&D to meet the strong demand for our best-in-class 
semiconductor platforms, including eVoSTM, eVerestTM and NavXTM, and our high-power artificial 
intelligence data center solutions. Our design-win momentum in Industrial and Medical continued to 
build, fueled by a healthy stream of new products, an enhanced customer-friendly website, and 
increased engagement with our distribution partners. Lastly, we are executing our financial 
initiatives by driving higher gross margins, controlling costs to fund critical program investments, 
and growing our cash position. 
Looking forward, I believe Advanced Energy will extend its leadership in the precision power 
market. Customer qualification activity has been strong, and we expect to gain meaningful share as 
the market recovers. We expect our manufacturing and cost optimization initiatives to enable 
structurally higher margins and meaningful cash flow generation. In addition, we will continue to 
pursue strategic acquisitions for inorganic growth and complementary technologies. 
At our November 2024 Analyst Day, we outlined a 2030 target model, which calls for doubling 
revenue, expanding gross margin, and growing earnings per share. With a diverse set of attractive 
 
end markets, strong customer relationships, one of the broadest portfolios of power technologies, a 
large team of over 1,500 power engineers, and a highly capable factory network, I am confident in 
our ability to achieve those long-term goals. 
On behalf of our employees and Board of Directors, we thank you for your continued support. 
Best regards, 
 
/s/ Stephen D. Kelley

health, safety, environmental, and ethics best practices. 
Employee Engagement  
We are committed to providing a collaborative and productive work environment for our employees. We 
periodically conduct confidential employee surveys to solicit feedback on confidence in Company leadership, ethical 
conduct, work environment, career growth opportunities, and we continually evaluate suggestions on how we can make 
Advanced Energy a great place to work. We communicate the results of these confidential employee surveys with our 
employees, leaders, executive team, and Board of Directors and use the feedback to identify opportunities to drive 
improvements across our Company. In 2024, we launched Powering Technology Together, our employee value 
proposition, to highlight our commitment to providing a best-in-class employee experience for our people across the 
globe and to differentiate ourselves as an employer of choice. We believe our employee value proposition will help us 
build our employer brand and attract and retain the best talent.  
Total Rewards 
We provide market-competitive compensation and benefits to our employees to attract and retain a talented, 
highly engaged workforce. Our compensation programs are focused on equitable and fair pay practices, including 
market-based compensation.  

10 
Learning and Development 
We create growth and development opportunities to support our employees and offer internal and external 
learning and development opportunities. We also perform internal talent reviews and succession planning. We provide a 
10-week leadership essential training program for our people leaders across all corporate levels. We also have internship 
and graduate development programs designed to develop a talent pipeline.  
Community Involvement 
We have an active Community Investment Steering Committee and offer employees paid time off to participate 
in Company organized initiatives and volunteer with non-profit organizations of their choice. Our Child of Employee 
Scholarship Program, available to children of Advanced Energy employees, celebrates education accomplishments and 
provides financial support for them to pursue their career and learning goals. We also offer an annual Advanced Energy 
STEM (science, technology, engineering, and mathematics) Scholarship in the U.S. to support and develop emerging 
talent in STEM. 
Environmental Matters 
We are subject to federal, state, and local environmental laws and regulations, as well as the environmental laws 
and regulations of the foreign federal and local jurisdictions in which we have manufacturing and service facilities. We 
believe we are in material compliance with all such laws and regulations.

ITEM 1A.         RISK FACTORS 
Our business, financial condition, operating results, and cash flows can be impacted by a number of factors, 
including, but not limited to, those set forth below, any of which could adversely impact our results and result in a 
decline in the value or loss of an investment in our common stock. Other factors may also exist that we cannot anticipate 
or that we currently do not consider to be material based on information that is currently available. These risks and 
uncertainties have the potential to materially affect our business, financial condition, results of operations, cash flows 
and future results. Such risks and uncertainties may also impact the accuracy of forward-looking statements included in 
this Form 10 - K and other reports we file with the SEC. 
Business and Industry Risks 
The industries in which we compete are subject to unpredictable fluctuation or cycles, which may be volatile. 
As a supplier to the global semiconductor equipment, industrial, medical, data center computing, 
telecommunication, and networking industries, we are subject to business fluctuations, the timing, length, and volatility 
of which can be difficult to predict. We are impacted by sudden changes in customers’ manufacturing capacity 
requirements and spending, which depend in part on technology transitions, capacity utilization, demand for customers’ 
products, inventory levels relative to demand, access to affordable capital, and changes in geopolitical factors, including 
tariffs. These changes have affected the timing and amount of customers’ purchases and investments in technology, and 
continue to affect our orders, net revenue, operating expenses, and net income. In addition, several of the markets in 
which we compete are highly cyclical and experience downturns characterized by diminished product demand, 
production overcapacity, high inventory levels, and price erosion, which has caused, and in the future could cause, our 
revenue and gross margin to decline, adversely impacting our results of operations. It is difficult to predict the timing, 
length, and severity of such fluctuations and downturns, and we may not be able to respond adequately or quickly to the 
changes in demand. 
To meet rapidly changing demand in each of the industries we serve, we must effectively manage our resources 
and production capacity. During periods of decreasing demand for our products, we must be able to appropriately align 
our cost structure with prevailing market conditions, effectively manage our supply chain, and motivate and retain key 
employees. During periods of increasing demand, we must have enough manufacturing capacity and inventory to fulfill 
customer orders, effectively manage our supply chain, and attract, retain, and motivate enough qualified individuals. If 
we are not able to timely and appropriately adapt to changes in our business environment or to accurately assess where 
we are positioned within a business cycle, our business, financial condition, or results of operations may be materially 
and adversely affected. 
For example, the semiconductor industry appears to be recovering from a cyclical downturn, and the Industrial 
and Medical market and Telecom and Networking market are rebalancing elevated inventory levels, which have 
adversely impacted demand for our products. If the semiconductor industry’s recovery does not continue as anticipated, 
if the length, severity, and/or volatility of the lower demand environments in the Industrial and Medical market and 
Telecom and Networking market exceeds our expectations, if we fail to achieve further growth in our other markets, our 
results of operations could be adversely impacted. 
We must achieve design wins to retain our existing customers and to obtain new customers, although design wins 
achieved may not necessarily result in substantial revenue or gross profit. 
Driven by continuing technology migration and changing customer demand, the markets we serve are 
constantly changing in terms of advancement in applications, core technology, and competitive pressures. New products 
designed for capital equipment manufacturers typically have a lifespan of many years. Increasingly, we are required to 
accelerate our investment in research and development to meet the time-to-market, performance, and technology 
adoption cycle needs of our customers simply to compete for design wins. Given such up-front investments we make to 
develop, evaluate, and qualify products in the design win process, our success and future growth depend on our products 
being designed into our customers’ new generations of equipment as they develop new technologies and applications. 
We must work with these manufacturers early in their design cycles to modify, enhance, and upgrade our products or 

12 
design new products that meet the requirements of their new systems. The design win process is highly competitive, the 
design windows may be narrow, and there is no assurance we will succeed with new design wins for our existing 
customers or new customers’ next generations of equipment. For example, in the last few years, we have made 
significant investments to launch new technology platforms and products into the semiconductor and industrial and 
medical markets. If existing or new customers do not choose our designs or we cannot agree to pricing, volumes, and 
other key commercial terms with these customers, our market share may decline, potential revenues related to the 
lifespan of our products may not be realized, and our business, financial condition, and results of operations could be 
materially and adversely impacted. Further, our ability to generate revenue or gross profit from design wins is in part or 
wholly dependent upon the success of our customers’ solutions. 
Failure to accurately forecast customer demand, supply chain disruptions, or manufacturing interruptions or delays 
could affect our ability to meet customer demand, lead to higher costs, or result in excess or obsolete inventory. 
We place orders with many of our suppliers based on our expectations as to demand for our products and our 
customers’ forecasts. As the quarter and the year progress, such demand and product mix can change rapidly or we may 
realize that our customers’ expectations were overly optimistic or pessimistic, especially when industry or general 
economic conditions change.  
Our sales are primarily made on a purchase order basis or are pulled from “just in time” bins or hubs by our 
customers, and we generally do not have long-term purchase commitments from our customers. As a result, we are 
limited in our ability to predict the level of future revenue or commitments from our current customers, which may 
diminish our ability to allocate labor, materials, and equipment in the manufacturing process effectively. In addition, we 
may purchase inventory in anticipation of sales that do not materialize, resulting in excess and obsolete inventory write-
offs. Customers may delay delivery of products or cancel orders prior to shipment and may not be subject to cancellation 
penalties. Delays in delivery schedules and/or customer changes to backlog orders during any particular period could 
cause a decrease in revenue and have a material adverse effect on our business and results of operations. Orders with our 
suppliers cannot always be amended in response to changing demand conditions.  
In addition, to assure availability of certain components or obtain priority pricing, we have entered into 
contracts with some of our suppliers that require us to purchase a specified number of components and subassemblies 
each quarter, even if we are not able to use such components or subassemblies. Moreover, we have obligations to some 
of our customers to hold a minimum amount of finished goods in inventory to fulfill just in time orders, regardless of 
whether the customers expect to place such orders. We currently have firm purchase commitments and agreements with 
various suppliers to ensure the availability of components. If demand for our products does not meet expected levels, we 
might not be able to use all of the components that we are required to purchase under these commitments and 
agreements, and our cost of revenue may increase, which could have a material adverse effect on our results of 
operations. If demand for our products exceeds our customers’ and our forecasts, we may not be able to timely obtain 
enough raw materials, parts, components, or subassemblies, on favorable terms or at all, to fulfill the excess demand. 
Furthermore, some of our products have lengthy lifecycles and are subject to supplier parts obsolescence, and sole-
sourced parts can create challenges in terms of purchasing parts on reasonable terms and lead-times. These situations 
may lead to customers cancelling orders prior to shipment causing a decrease in revenue, which may have a material 
adverse effect on our business and results of operations.  
In recent years, there was a shortage of critical components caused by a variety of factors, including increased 
demand for electronic components used in a wide variety of industries, the pandemic-driven rise in consumer demand 
for technology goods, logistics-related disruptions in shipping, capacity limitations at some suppliers, and labor 
shortages. These supply constraints led to longer lead times in procuring materials and subcomponents and, in some 
cases, meaningfully higher costs for the subcomponents. Our revenues, earnings, and cash flow may be adversely 
impacted if these conditions reoccur. 
We are exposed to risks associated with worldwide financial markets and the global economy. 
Uncertain or adverse economic and business conditions, including uncertainties and volatility in the financial 
markets, rising inflation and interest rates, economic recession, national debt, and fiscal or monetary concerns, could 

13 
materially adversely impact our operating results and financial condition. Disruptions in the global economy or financial 
markets, higher interest rates and market volatility could have an adverse impact on our access to and cost of capital. 
Additionally, tightening of credit markets, turmoil in the financial markets, and a weakening global economy have 
contributed in the past and could again contribute to slowdowns in the industries in which we operate and adversely 
impact the global demand for our products. Some of our key markets ultimately depend on a combination of consumer 
and business spending. Economic uncertainty exacerbates negative trends in consumer and business spending and may 
cause our customers to delay, cancel, or refrain from placing orders. Difficulties or increased costs in obtaining capital 
and uncertain market conditions may also lead to customer liquidity constraints, a reduction of revenue, and greater 
instances of nonpayment or other failures to perform their obligations. Adverse or uncertain economic conditions may 
similarly affect our key suppliers, which could affect their ability to deliver parts and result in delays for our products. 
Further, these conditions and uncertainty about future economic conditions could also make it challenging for us to 
forecast our operating results and evaluate the risks that may affect our business, financial condition, and results of 
operations.  
If we are unable to maintain our pricing strategy or adjust our business strategy successfully for some of our product 
lines to reflect our customers’ price sensitivity, our business and financial condition could be harmed. 
Our customers continually exert pressure on us to reduce our prices and extend payment terms and we have 
been and may be required to enter into long term reduced pricing agreements, extended payment terms, exclusivity 
arrangements, and other unfavorable contract terms. In addition, we compete in markets in which customers may dual or 
multi-source their power supply products. We believe some of our Asia-based competitors benefit from local 
governmental funding incentives and purchasing preferences from end-user customers in their respective countries. If 
competition against any of our product lines should come to focus solely on price rather than on product performance 
and technology innovation, we would need to adjust our business strategy, product offerings, and product costs 
accordingly, and if we are unable to do so, our business, financial condition, and results of operations could be materially 
and adversely affected. Conversely, in 2022, we not only increased prices but also implemented surcharges across many 
of our products to reflect our higher supply chain costs. Although these price changes were generally accepted by our 
customers, we did experience some loss of business. We continue to execute our pricing strategies and practices; 
however, any future price increases could make our products less competitive in the market over time and could have an 
adverse effect on our results of operations.  
A significant portion of our revenue and accounts receivable are concentrated among a few customers.  
Consistent with prior years, a limited number of customers accounted for a significant portion of our business, 
revenue and accounts receivable. A significant decline in revenue from these or our other large customers, the loss of 
these or other large customers, or any inability to collect from large customers could materially and adversely impact our 
business, results of operations, and financial condition.  
We expect that revenue from a few large customers will continue to account for a significant percentage of our 
total revenue in future periods; however, we generally do not have long-term purchase commitments. If our largest 
customers do not place orders, or if they substantially reduce, delay, or cancel orders, we may not be able to replace their 
business on a timely basis or at all. As a result, our future success depends on our ability to maintain and strengthen our 
existing customer relationships, build new customer relationships, and diversify our customer base. For more 
information about our significant customers, see Note 3. Revenue in Part II, Item 8 “Financial Statements and 
Supplementary Data.” 
If our information security measures are breached, disrupted, or fail, we may incur significant legal and financial 
exposure and liabilities.  
As part of our day-to-day business, we process, transmit and store our own confidential data and certain data 
about our customers and employees in our global information technology system. We are subject to ongoing data 
security threats, including phishing attempts, denial of service attacks, ransomware, viruses, and other malware, 
employee error or malfeasance, theft, natural disasters, and hardware or software malfunctions, any one of which could 
compromise our data security, cause the loss of critical data, or disrupt operations, which could materially adversely 

14 
affect our business and results of operations. Additionally, third parties may attempt to fraudulently induce employees or 
customers into disclosing sensitive information such as usernames, passwords, or other information to gain access to our 
customers’ data or our data or our information technology systems. We and our third party providers have experienced, 
and expect to continue to experience, cybersecurity events or confidential information theft incidents, some of which 
could be devastating. We continue to devote significant resources to cybersecurity, IP protection, data encryption, and 
other measures to protect our systems and data from unauthorized external access or internal misuse, and we may be 
required to expend greater resources in the future for cybersecurity protection, compliance, and remediation, especially 
in the face of continuously evolving and increasingly sophisticated cybersecurity threats and privacy and data protection 
laws. 
Despite our implementation of cybersecurity measures, there is no assurance that our actions will be sufficient 
to prevent future threats and incidents. Because the techniques used to obtain unauthorized access or to sabotage systems 
change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these 
techniques or to implement adequate preventative measures. A cybersecurity event or other breach, disruption, or failure 
of our information and operational systems, could: 
• 
result in the disclosure, misuse, corruption, or loss of our confidential business information, intellectual 
property including trade secrets, or our customers’ data;  
• 
damage our reputation;  
• 
lead to a loss of confidence by our current and potential customers; 
• 
adversely impact our future revenue; 
• 
disrupt our business; 
• 
divert management attention; and  
• 
expose us to significant remediation costs, legal liability, and litigation risk.  
Difficulties with the implementation or transition to our next generation enterprise resource planning and other new 
enterprise-wide information technology system applications could harm our business and impact our results of 
operations. 
Our business could be adversely affected to the extent we fail to appropriately manage, expand, and update our 
information technology infrastructure. In particular, we are in the process of implementing a global enterprise resource 
planning (“ERP”) system and other enterprise-wide applications that will upgrade and standardize our information 
systems. These implementations are expected to occur in phases over the next several years. Any delays, challenges, or 
failure to achieve our implementation goals may adversely impact our operations. In addition, the failure to anticipate the 
necessary readiness and training needs, manage the transition to systems, or appropriately convert historical and 
concurrent data could lead to business disruption and potential loss of business. Failure or abandonment of any part of 
the ERP system could result in a write-off of part or all of the costs that have been capitalized on the project. 
The loss of and inability to attract and retain key personnel could significantly harm our results of operations and 
competitive position.  
Our success depends to a significant degree upon the continuing contributions of our management, technical, 
marketing, and sales employees. We may not be successful in retaining our employees or attracting and retaining 
additional skilled personnel as required. If we are unable to attract, retain, and motivate qualified employees and leaders, 
we may be unable to fully capitalize on current and new market opportunities, which could adversely impact our 
business and results of operations. Our success in hiring and retaining employees depends on a variety of factors, 
including the attractiveness of our compensation and benefit programs, global economic or political and industry 
conditions, our organizational structure, our reputation, culture and working environment, competition for talent and the 
availability of qualified employees, the readiness for and availability of career development opportunities, and our ability 
to offer a challenging and rewarding work environment. We have experienced, and may continue to experience, 
increasing costs to attract and retain needed talent, driven by macroeconomic conditions and a highly competitive labor 
market.  

15 
In addition, the loss or retirement of key employees presents particular challenges to the extent the departing 
employee had particularly valuable knowledge or experiences. This requires us to identify and train existing or new 
employees to perform necessary functions, which we may be unable to do, or which could result in unexpected costs, 
reduced productivity, or difficulties with respect to internal processes and controls. If we fail to have succession plans in 
place or our succession plans do not operate effectively, we may not be able to maintain continuity and our business 
could be adversely affected. 
We are consolidating our manufacturing footprint, which brings risks.  
Our manufacturing facilities are located globally, and the majority of our products are manufactured in a select 
few key facilities. Most facilities are under operating leases, and interruptions in operations could be caused by early 
termination of existing leases by landlords or failure by landlords to renew existing leases upon expiration, including the 
possibility that suitable operating locations may not be available in proximity to existing facilities, which could result in 
labor or supply chain risks. Additionally, we are currently restructuring to optimize and consolidate our manufacturing 
operations and improve operating efficiencies, and we continue to evaluate our manufacturing facilities and may decide 
to conduct additional optimization and consolidation initiatives. These plans and any future initiatives may or may not be 
successful in achieving our intended results. If the expected costs and charges are greater than anticipated, the estimated 
cost savings are lower than anticipated, or we experience a loss of continuity or inefficiency during transitional periods, 
our business and results of operations may be adversely affected.  
Disruptions to our manufacturing or other operations or the operations of our customers or suppliers, due to natural 
or other disasters, uncontrollable events or other issues could affect our results of operations.  
Certain of our manufacturing and other operations are in locations subject to natural disasters, such as severe 
weather and geological events, including earthquakes or tsunamis, which could disrupt operations. Natural disasters, 
uncontrollable occurrences (including the emergence of pandemics, epidemics, or widespread outbreaks of infectious 
disease), or other operational issues at any of our manufacturing or other facilities could significantly reduce or disrupt 
our productivity and could prevent us from meeting our customers’ requirements in a timely manner, or at all. In 
addition, our suppliers and customers are also subject to natural and other disaster risk exposure. A natural disaster, fire, 
explosion, pandemic, or other event that results in a prolonged disruption to our operations or the operations of our 
customers or suppliers, may materially adversely affect our business, workforce, supply chain, results of operations, 
financial condition, or cash flows.  
Our long-term success and results of operations depend on our ability to successfully identify, close, integrate, and 
realize the anticipated benefits from our acquisitions and strategic investments. 
As part of our business strategy, we have and will likely continue to acquire companies or businesses and make 
investments to further our business. Risks associated with these transactions are many, including the following which 
could adversely affect our financial results: 
• 
the inability to source or complete transactions timely or at all; 
• 
any obligation to pay a termination fee or undergo litigation resulting from failed deals; 
• 
the failure to perform adequate due diligence on target companies; 
• 
the failure to realize expected revenues, gross and operating margins, net income, and other returns from 
acquired businesses; 
• 
the inability to successfully integrate product and/or service offerings to realize anticipated benefits from 
business combinations; 
• 
the inability to integrate acquired business into our existing enterprise resource planning and other global 
information technology systems to realize productivity improvement and cost efficiencies; 
• 
we have incurred and will incur additional depreciation and amortization expense over the useful lives of 
certain assets acquired in connection with business combination and, to the extent that the value of 

16 
goodwill or intangible assets acquired in connection with a business combination becomes impaired, we 
may incur additional material charges related to impairment of those assets; 
• 
deterioration in our effective tax rate; 
• 
a failure to retain and motivate key employees of acquired businesses; 
• 
our ability to maintain appropriate business processes, procedures, and internal controls at the acquired 
business; 
• 
litigation or claims associated with a proposed or completed transaction; and 
• 
unknown, underestimated, undisclosed or undetected commitments or liabilities or non-compliance by 
acquired business with laws, regulations, or policies.  
Our products may suffer from defects or errors leading to increased costs, damages, or warranty claims.  
Our products use complex system designs and components that may contain errors or defects in designs, 
manufacturing, firmware, software, component parts, or other materials. The manufacture of these products often 
involves a highly complex and precise process and the utilization of specially qualified components. The production of 
many of our products also requires highly skilled labor. As a result of the technical complexity of these products, design 
defects, skilled labor turnover, changes in our or our suppliers’ manufacturing processes or the inadvertent use of 
defective or nonconforming materials or components by us or our suppliers could adversely affect our manufacturing 
quality and product reliability. To the extent our products are defective or fail, we might be required to repair, redesign, 
replace, or recall those products, pay damages (including liquidated damages), or fulfill warranty claims, and we could 
suffer significant expenses as well as harm to our reputation. Furthermore, some of our products are used in medical 
device applications where malfunction of the device could result in serious injury. We accrue a warranty reserve for 
estimated costs to provide warranty services, including the cost of technical support, product repairs, and product 
replacement for units that cannot be repaired. Our estimate of costs to fulfill our warranty obligations is based on 
historical experience and expectation of future conditions. To the extent we experience increased warranty claim activity 
or increased costs associated with servicing those claims, our warranty accrual will increase, resulting in decreased gross 
profit. 
Our legacy inverter products may suffer higher than anticipated litigation, damage, or warranty claims.  
Our legacy inverter products (of which we discontinued the manufacture, engineering, and sale in 
December 2015 and which are reflected as discontinued operations in this filing) contain components that may contain 
errors or defects and were sold with product warranties ranging from one to 20 years. If any of our products are defective 
or fail because of their design, we might be required to repair, redesign, or recall those products or to pay damages 
(including liquidated damages) or warranty claims, and we could suffer significant harm to our reputation. We have 
experienced claims from customers and suppliers and are involved in litigation related to the legacy inverter product 
line. We review such claims and vigorously defend against such lawsuits in the ordinary course of our business. We 
cannot assure that any such claims or litigation will not have a material adverse effect on our business or financial 
statements. Our involvement in such litigation could result in significant expense to us and divert the efforts of our 
technical and management personnel. We also accrue a warranty reserve for estimated costs to provide warranty services 
including the cost of technical support, product repairs, and product replacement for units that cannot be repaired. Our 
estimate of costs to fulfill our warranty obligations is based on historical experience and expectation of future conditions. 
To the extent we experience increased warranty claim activity or increased costs associated with servicing those claims, 
our warranty accrual will increase, resulting in additional expenses in our Consolidated Statements of Operations in 
future periods. We plan to continue supporting inverter customers with service maintenance and repair operations. This 
includes performing service to fulfill obligations under existing service maintenance contracts. There is no certainty that 
these contracts can be performed profitably, and our business could be adversely affected by higher than anticipated 
product failure rates, loss of critical service technician skills, an inability to obtain service parts, customer demands and 
disputes, and the cost of repair parts, among other factors. 

17 
International Operations Risks 
We are subject to risks inherent in international operations. 
We are a global organization. We have employees in 16 countries, our manufacturing facilities are located 
across the globe (mainly in the Asia-Pacific region), and revenue from customers outside the United States represented 
66% of our total revenue during the year ended December 31, 2024.  
Given the global nature of our business, we have both domestic and international concentrations of cash and 
investments. The value of our cash, cash equivalents, and marketable securities can be adversely affected by liquidity, 
credit deterioration, inflation, foreign currency exchange rate fluctuations, financial results, economic risk, political risk, 
sovereign risk, or other factors. 
Additionally, our success producing goods internationally and competing in international markets is subject to 
our ability to manage various operational risks and difficulties, including, but not limited to:  
• 
our ability to effectively manage our employees at remote locations who are operating in different business 
environments from the United States; 
• 
our ability to develop and maintain relationships with suppliers and other local businesses; 
• 
interruptions to our and/or our suppliers’ supply chain; 
• 
global trade issues and changes in and uncertainties with respect to trade and export regulations, trade 
policies and sanctions, tariffs, and international trade disputes, including export regulations for certain 
exports to China and any retaliatory measures; 
• 
compliance with product safety requirements and standards that are different from those of the United 
States; 
• 
variations and changes in laws applicable to our operations in different jurisdictions, including 
enforceability of contract rights; 
• 
ineffective or inadequate legal and physical protection of intellectual property rights in certain countries; 
• 
delays or restrictions on personnel travel and in shipping materials or finished products between and within 
countries; 
• 
political instability, international hostilities, natural disasters, health epidemics, disruptions in financial 
markets, and deterioration of economic conditions; 
• 
our ability to maintain appropriate business processes, procedures, and internal controls, and comply with 
environmental, health and safety, anti-corruption, and other regulatory requirements; 
• 
customs regulations including customs audits in various countries that occur from time to time; 
• 
the ability to provide enough levels of technical support in different locations; 
• 
our ability to obtain business licenses that may be needed in international locations to support expanded 
operations; 
• 
changes in tariffs, income tax, value added tax, and foreign currency exchange rates; and 
• 
laws and regulations regarding privacy, data use and processing, data privacy and protection, cybersecurity, 
and network security. 
 
 
 

18 
Our operations in the Asia Pacific region, including China, are subject to significant political and economic 
uncertainties over which we have little or no control and we may be unable to alter our business practice in time to 
avoid reductions in revenues.  
A significant portion of our operations and supply chain outside the United States are located in the Asia Pacific 
region, including China, which exposes us to risks, such as exchange controls and currency restrictions, changes in local 
economic conditions, changes in customs regulations and tariffs, changes in tax policies, changes in local laws and 
regulations, possible retaliatory government actions, potential inability to enforce intellectual property protection or 
contracts terms, and changes in U.S. policy regarding overseas manufacturing and export controls. The U.S. and China 
regularly have significant disagreements over geopolitical, trade, and economic issues. Any escalating political 
controversies between the U.S. and China, whether or not directly related to our business, could have a material adverse 
effect on our operations, business, results of operations, and financial condition. Additionally, the Chinese government 
exercises substantial control over the Chinese economy, and our operations and supply chain in China may be subject to 
various government and regulatory interference. Policy changes, preferential treatment of local companies, or the 
imposition of new, stricter regulations or interpretations of existing regulations could require changes to our operating 
activities, increase our costs, or limit our ability to sell products in China. We continuously evaluate the risk of 
operations in China, including manufacturing and supply chain, and the potential financial impact to our operations. 
Unfavorable currency exchange rate fluctuations may lead to lower operating margins, or may cause us to raise 
prices, which could result in reduced revenue. 
Currency exchange rate fluctuations could have an adverse effect on our revenue and results of operations, and 
we could experience losses with respect to forward exchange contracts into which we may enter. Unfavorable currency 
fluctuations could significantly increase the labor and other costs incurred in the operation of our international facilities 
and the cost of raw materials, parts, components, and subassemblies that we source there, which could materially and 
adversely affect our results of operations. These increased costs could require us to increase prices to foreign customers, 
which could result in lower net revenue from such customers. Alternatively, if we do not adjust the prices for our 
products in response to unfavorable currency fluctuations, our results of operations could be materially and adversely 
affected. In addition, we have large, long-term liabilities, such as local lease and pension liabilities in Asia and Europe 
creating more significant exposure to fluctuations in numerous currencies. We do not attempt to hedge these exposures 
given the long-term nature of the underlying liabilities and the non-cash nature of the foreign exchange gain or loss.  
Regulatory, Legal, Tax, and Compliance Related Risks 
Continued restrictive global trade regulatory environment coupled with increasingly complex rules have 
adversely impacted our business, could further impact our business, and could erode the competitiveness of our 
products compared to local and global competitors. 
As a global company, we are subject to the trade policies, export/import controls, and other rules and 
regulations, including tariffs, trade sanctions, and license requirements of the U.S. and other government authorities. We 
expect continued exposure to risk arising from ongoing activity in both the promulgation of newly imposed global trade 
regulations and increased enforcement of existing regulations. The implementation and interpretation of these complex 
rules and other regulatory actions is uncertain and evolving, trending towards continued increasing restrictions, which is 
deleterious to our business and challenging for us to manage our operations and forecast our operating results.  
Since October 2022, we have been particularly affected by U.S. government-imposed export regulations on 
U.S. semiconductor and supercomputing technology and related parts and services sold in China. Over the past few 
years, the U.S. government has introduced several additional regulatory changes that impose extensive restrictions and 
compliance obligations, and Chinese customers may replace us with competitors who are not subject to U.S. export 
rules. Additionally, our ability to maintain business in China may be dependent at least in part on obtaining export 
licenses. Obtaining export licenses may be difficult, costly, and time-consuming, and there is no assurance we will be 
issued licenses in time to meet customer requirements or at all.  

19 
Recently, we were also subject to new anti-dumping and countervailing duty rates and increased Section 301 
tariffs that took effect in 2024 and 2025 for certain products we import from China. The Trump Administration has 
threatened further tariffs on imports. If we are unable to mitigate the impact of these import restrictions, our costs and 
results of operations could be adversely affected. 
We cannot predict the extent to which unfavorable international trade policies may be implemented in the future 
and to what extent our business may be impacted. Future regulatory changes that could materially and adversely affect 
our business include but are not limited to additional or increased tariffs, additions or updates to various restricted party 
lists, further restrictions on selling products to entities in certain countries whose actions or functions are intended to 
support policies contrary to U.S. national security, new customs rules or requirements, and retaliatory trade actions or 
trade wars. Additionally, with increasing geopolitical risks, we might experience customers or governments of our 
customers promoting their own domestic businesses and competitors. Any or all of the foregoing could decrease demand 
for our products, increase costs and decrease margins, reduce the competitiveness of our products, or restrict our ability 
to sell products, provide services or purchase necessary equipment and supplies, which in turn could have a material and 
adverse effect on our business, results of operations, or financial condition. 
We are highly dependent on our intellectual property. 
Our success depends significantly on our proprietary technology. We attempt to protect our intellectual property 
rights through a variety of methods including trade secrets, patents, and non-disclosure agreements; however, we might 
not be able to protect our technology, and customers or competitors might be able to develop similar technology 
independently. Infringement, misappropriation, and unlawful use of our intellectual property rights, and resulting 
unauthorized manufacture or sale of equipment using our IP rights, could result in lost revenue. Monitoring and 
detecting any unauthorized use of intellectual property is difficult and costly and we cannot be certain that the protective 
measures we have implemented will completely prevent theft or misuse. If we are unable to protect our intellectual 
property successfully, our business, financial condition, and results of operations could be materially and adversely 
affected. 
Patents, trademarks, and trade secret protection may not be adequate to deter infringement or misappropriation 
of our proprietary rights. For example, patents issued to us may be challenged, invalidated, or circumvented. The loss or 
expiration of any of our key patents could lead to a significant loss of sales of certain of our products and could 
materially affect our future operating results. The process of seeking patent protection can be time consuming and 
expensive and patents may not be issued for currently pending or future applications. Moreover, our existing patents or 
any new patents that may be issued may not be sufficient in scope or strength to provide meaningful protection or any 
commercial advantage to us. We may initiate claims, enforcement actions or litigation against third parties for 
infringement of our proprietary rights, which claims could result in costly litigation, the diversion of our technical and 
management personnel, and the assertion of counterclaims by defendants. 
In addition, the laws of some foreign countries might not afford our intellectual property the same protections 
as do the laws of the United States. Our intellectual property is not protected by patents in several countries in which we 
do business, and we have limited or no patent protection in other countries, including China. Consequently, 
manufacturing our products in China may subject us to an increased risk that unauthorized parties may attempt to copy 
our products or otherwise obtain or use our intellectual property. Generally, our efforts to obtain international patents 
have been concentrated in the European Union and Korea, Japan, and Taiwan. 
Third parties may also assert claims against us and our products. Claims that our products infringe the rights of 
others, whether or not meritorious, can be expensive and time-consuming to defend and resolve, and may divert the 
efforts and attention of management and personnel. The inability to obtain rights to use third party intellectual property 
on commercially reasonable terms could also have an adverse impact on our business. In addition, we may face claims 
based on the theft or unauthorized use or disclosure of third party trade secrets and other confidential business 
information. Any such incidents and claims could severely harm our business and reputation, result in significant 
expenses, harm our competitive position, and prevent us from selling certain products, all of which could have a material 
and adverse impact on our business and results of operations.  

20 
Our supply chain is subject to regulatory risk.  
Requirements applicable to our supply chain include rules aimed at promoting transparency as well as rules that 
restrict sourcing from certain locations or suppliers. For example, rules aimed at extinguishing forced labor require 
extensive efforts to map supply chains effectively and efficiently beyond tier 1 suppliers for any involvement in human 
rights abuses. Goods suspected of being manufactured with forced labor could be blocked from importation into the 
U.S., which could impact revenue. Another possible risk is foreign governments that restrict our access to supply; for 
example, if China were to further restrict export of rare earth minerals, our suppliers’ ability to obtain such supply may 
be constrained and we may be unable to obtain sufficient quantities, or obtain supply in a timely manner, or at a 
commercially reasonable cost. 
We are, and expect to continue to be, involved in litigation. Legal proceedings are costly and could have a material 
adverse effect on our commercial relationships, business, financial condition, and operating results.  
We may be involved in legal proceedings, litigation, enforcement actions, or claims arising from our business, 
including, but not limited to, those regarding product performance, product warranty, product certification, product 
liability, patent infringement, misappropriation of trade secrets, other intellectual property rights, antitrust, 
environmental regulations, securities, contracts, unfair competition, employment, workplace safety, and other matters. 
Legal proceedings, enforcement actions and claims, whether with or without merit, and associated internal 
investigations, may be time-consuming and expensive to prosecute, defend or conduct; divert management’s attention 
and other resources; inhibit our ability to sell our products or services; prevent us from using our technology; result in 
adverse judgments for damages, injunctive relief, penalties, and fines; and adversely affect our business. We can provide 
no assurance of the outcome of these legal proceedings, enforcement actions, or claims or that the insurance we maintain 
will provide coverage or be adequate to cover them. 
Changes in tax laws, tax rates, or mix of earnings in tax jurisdictions in which we do business could impact our 
future tax liabilities and related corporate profitability.  
We are subject to income taxes in the U.S. (federal and state) and numerous foreign jurisdictions. Tax laws, 
regulations, and administrative practices in various jurisdictions by their nature are complex and may be subject to 
significant change due to economic, political, and other conditions, and significant judgment is required in evaluating 
and estimating our provision and accruals for these taxes. As both domestic and foreign governments contemplate or 
make changes in tax law, our results could be adversely affected. Further, there are many transactions that occur during 
the ordinary course of business for which the ultimate tax determination is uncertain. Our effective tax rates could be 
adversely affected by earnings being lower than anticipated in jurisdictions where we have lower statutory rates and 
earnings higher than anticipated in jurisdictions where we have higher statutory rates, losses incurred in jurisdictions for 
which we are not able to realize the related tax benefit, changes in foreign currency exchange rates, entry into new 
businesses and geographies and changes to our existing businesses, acquisitions (including integrations) and 
investments, changes in our deferred tax assets and liabilities and their valuation, and changes in the relevant tax, 
accounting, and other laws, regulations, administrative practices, principles, and interpretations, including fundamental 
changes to the tax laws applicable to corporate multinationals. 
Furthermore, due to shifting economic and political conditions, tax policies, laws, or rates in various 
jurisdictions may be subject to significant changes in ways that could harm our financial condition and operating results. 
For example, various jurisdictions around the world have enacted or are considering revenue-based taxes such as digital 
services taxes and other targeted taxes, which could lead to inconsistent and potentially overlapping international tax 
regimes. The Organization for Economic Cooperation and Development is coordinating negotiations with the goal of 
achieving consensus around substantial changes to international tax policies, including the implementation of a 
minimum global effective tax rate of 15%. These changes could increase our effective tax rate and cash tax payments 
could increase in future years, create additional compliance burdens, and/or require changes to our tax compliance 
processes. 

21 
Increased governmental action on income tax regulations could adversely impact our business.  
International governments have heightened their review and scrutiny of multinational businesses like ours, 
which could increase our compliance costs and future tax liability to those governments. As governments continue to 
look for ways to increase their revenue streams, they could increase audits of companies to accelerate the recovery of 
monies perceived as owed to them under current or past regulations. As we are subject to examination by tax authorities 
in every jurisdiction where we do business, an unfavorable audit outcome could adversely affect us.  
Changes in our provision for income taxes or adverse outcomes resulting from examination of our income tax 
returns could adversely affect our results.  
Our provision for income taxes is subject to volatility and could be adversely affected by earnings being lower 
than anticipated in countries that have lower tax rates and higher than anticipated in countries that have higher tax rates; 
by changes in the valuation of our deferred tax assets and liabilities; by changes, regulations, and interpretations of 
research and development capitalization and tax credit regulations, foreign-derived intangible income (“FDII”), global 
intangible low-tax income (“GILTI”) and base erosion and anti-abuse tax (“BEAT”) laws; by expiration of or lapses in 
tax incentives; by transfer pricing adjustments, including the effect of acquisitions on our legal structure; by tax effects 
of nondeductible compensation; by tax costs and related tax effects from intercompany realignments; by changes in 
accounting principles; or by changes in tax laws and regulations, treaties, or interpretations thereof, including changes to 
the taxation of earnings of our foreign subsidiaries, the deductibility of expenses attributable to foreign income, and the 
foreign tax credit rules. Significant judgment is required to determine the recognition and measurement attribute 
prescribed in the accounting guidance for uncertainty in income taxes. The Organization for Economic Co-operation and 
Development (“OECD”), an international association, including the U.S., has made changes to numerous long-standing 
tax principles. There can be no assurance that these changes, once adopted by countries in which we operate, will not 
have an adverse impact on our provision for income taxes. Further, because of certain of our ongoing employment and 
capital investment actions and commitments, our income in certain countries is subject to reduced tax rates. Our failure 
to meet these commitments could adversely impact our provision for income taxes. In addition, we are the subject of 
regular examination of our income tax returns by tax authorities. We regularly assess the likelihood of adverse outcomes 
resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no 
assurance that the outcomes from these continuous examinations will not have an adverse effect on our operating results 
and financial condition. 
Our business is subject to complex and evolving U.S. and international laws and regulations regarding privacy and 
data protection. Many of these laws and regulations are subject to change and uncertain interpretation and could 
result in claims, changes to our business practices, penalties, increased cost of operations, or declines in customer 
growth or engagement, or otherwise harm our business.  
Regulatory authorities around the world have implemented or are considering several legislative and regulatory 
proposals concerning data protection. In addition, the interpretation and application of consumer and data protection 
laws in the U.S., Europe, China and elsewhere are often uncertain and in flux. It is possible that these laws may be 
interpreted and applied in a manner that is inconsistent with our data practices. Violation of any of these rules could 
result in fines or orders requiring that we change our data practices, which could have an adverse effect on our business 
and results of operations. Complying with these various laws could cause us to incur substantial costs or require us to 
change our business practices in a manner adverse to our business. 
We are subject to numerous governmental regulations.  
We are subject to federal, state, local and foreign regulations, including environmental regulations and 
regulations relating to the design and operation of our products and control systems and regulations governing the 
import, export and customs duties related to our products. We might incur significant costs as we seek to ensure that our 
products meet safety and emissions standards, many of which vary across the states and countries in which our products 
are used. In the past, we have invested significant resources to redesign our products to comply with these directives. In 
addition, through previous acquisitions, we expanded our presence in the medical market to include more highly 
regulated applications and added a medical-certified manufacturing center to our operating footprint. We may encounter 

22 
increased costs to maintain compliance with the quality systems and other regulations and requirements that apply to the 
acquired business. Compliance with future regulations, directives, and standards could require us to modify or redesign 
some products, make capital expenditures, or incur substantial costs. Also, we may incur significant costs in complying 
with the numerous imports, exports, and customs regulations as we seek to sell our products internationally. If we do not 
comply with current or future regulations, directives, and standards: 
• 
we could be subject to fines and penalties; 
• 
our production or shipments could be suspended; and 
• 
we could be prohibited from offering particular products in specified markets. 
If we were unable to comply with current or future regulations, directives and standards, our business, financial 
condition, and results of operations could be materially and adversely affected. 
We are subject to risks associated with environmental, health, and safety regulations.  
We are subject to environmental, health, and safety regulations in connection with our global business 
operations, such as regulations related to the development, manufacture, sale, shipping, and use of our products; 
handling, discharge, recycling and disposal of hazardous materials used in our products or in producing our products; 
restrictions on the presence of certain substances in our products; the operation of our facilities; and the use of our real 
property. The failure or inability to comply with existing or future environmental, health and safety regulations, 
including with respect to energy consumption and climate change, could result in significant remediation or other legal 
liabilities; the imposition of penalties and fines; restrictions on the development, manufacture, sale, shipping, or use of 
certain of our products; limitations on the operation of our facilities or ability to use our real property; and a decrease in 
the value of our real property. We could also be required to alter our manufacturing, operations, and product design, and 
incur substantial expenses to comply with environmental, health and safety regulations. Any failure to comply with these 
regulations could subject us to significant costs and liabilities that could adversely affect our business, financial 
condition, and results of operations. 
Our failure to maintain appropriate environmental, social, and governance (“ESG”) practices and disclosures could 
result in reputational harm, a loss of customer and investor confidence, and adverse business and financial results.  
Failure to adequately maintain appropriate ESG practices that meet diverse stakeholder expectations may result 
in an inability to attract customers, the loss of business, diluted market valuation, and an inability to attract and retain top 
talent. Maintaining possibly unlawful ESG programs could expose us to litigation threat. In addition, standards and 
processes for measuring and reporting carbon emissions and other sustainability metrics may change over time, resulting 
in inconsistent data, or could result in significant revisions to our sustainability commitments or our ability to achieve 
them. Any scrutiny of our carbon emissions or other sustainability disclosures or our failure to achieve related goals 
could adversely impact our reputation or performance. As governments impose greenhouse gas emission reporting and 
climate risk assessment requirements, along with other ESG-related laws, we are subject to at least some of these rules 
and concomitant regulatory risk exposure. Also, certain customers request ESG related performance data in relation to 
our products. ESG compliance and reporting costly, and we could be at a disadvantage compared to companies that do 
not have similar reporting requirements or that have more resources to devote to ESG efforts.  
 
 
 

23 
Commercial and Financial Related Risks 
Our debt obligations and the restrictive covenants in certain of the agreements governing our debt could limit our 
ability to operate our business or pursue our business strategies, could adversely affect our business, financial 
condition, results of operations, and cash flows, and could significantly reduce stockholder benefits from a change of 
control event. 
Our debt obligations could make us more vulnerable to general adverse economic and industry conditions and 
could limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate, 
thereby placing us at a disadvantage to our competitors that have less debt. We may enter into additional debt obligations 
at any time. 
Our Credit Agreement, including the associated revolving line of credit, imposes financial covenants on us and 
our subsidiaries that require us to maintain a certain leverage ratio. The financial covenants place certain restrictions on 
our business that may affect our ability to execute our business strategy successfully or take other actions that we believe 
would be in the best interests of our Company. These include limitations or restrictions, among other things, on our 
ability and the ability of our subsidiaries to: 
• 
incur additional indebtedness;  
• 
pay dividends or make distributions on our capital stock or certain other restricted payments or 
investments; 
• 
conduct stock buybacks; 
• 
make domestic and foreign investments and extend credit; 
• 
engage in transactions with affiliates; 
• 
transfer and sell assets; 
• 
effect a consolidation or merger or sell, transfer, lease, or otherwise dispose of all or substantially all our 
assets; and 
• 
create liens on our assets to secure debt. 
Any breach of the covenants or other event of default could cause a default on our Credit Agreement, which 
could result in the entire outstanding balance at that time being immediately due and payable. Such breach or default 
may also constitute a default of our Convertible Notes, which could also result in the entire outstanding balance being 
immediately due and payable. Our assets and cash flow may not be sufficient to fully repay borrowings under our 
outstanding debt instruments if accelerated upon an event of default. If we are unable to repay, refinance, or restructure 
our indebtedness as required, or amend the covenants contained in these agreements, the lenders can exercise all rights 
and remedies available under our debt obligations or applicable laws or equity. There can be no assurance that we will 
have sufficient financial resources or be able to arrange financing to repay any borrowings at such time. 
Return on investments or interest rate declines on plan investments could result in additional unfunded pension 
obligations for our pension plan. 
We currently have unfunded obligations to our pension plans. The extent of future contributions to the pension 
plan depends heavily on market factors such as the discount rate used to calculate our future obligations and the actual 
return on plan assets which enable future payments. We estimate future contributions to the plan using assumptions with 
respect to these and other items. Changes to those assumptions could have a significant effect on future contributions. 
Additionally, a material deterioration in the funded status of the plan could increase pension expenses and reduce our 
profitability. See Note 15. Employee Retirement Plans and Postretirement Benefits in Part II, Item 8 “Financial 
Statements and Supplementary Data” contained herein. 

24 
Our intangible assets and goodwill may become impaired.  
We periodically review the carrying value of our intangible assets and goodwill. We consider any events or 
circumstances that might result in either a diminished fair value, and for intangible assets, a revised useful life. The 
events and circumstances include significant changes in the business climate, legal factors, operating performance 
indicators, and competition. Any impairment or revised useful life could have a material and adverse effect on our 
financial position and results of operations and could harm the trading price of our common stock.  
The conditional conversion features of the Convertible Notes, if triggered, may adversely affect our financial 
condition and operating results. 
In the event any of the conditional conversion features of the Convertible Notes are triggered, holders will be 
entitled to convert at any time during specified periods at their option. If one or more holders elect to convert, we would 
be required to settle any converted principal amount of such Convertible Notes through payment of cash, which could 
adversely affect our liquidity. In addition, even if holders do not elect to convert, we could be required under applicable 
accounting rules to reclassify all or a portion of the outstanding principal of the Convertible Notes as current rather than 
long-term liability, which would result in a material reduction of our net working capital. 
Conversion of the Convertible Notes may dilute the ownership interest of our stockholders and the existence of the 
Convertible Notes may depress the price of our common stock. 
The conversion of some or all of the Convertible Notes may dilute the ownership interests of our stockholders. 
Upon conversion, we have the option to pay or deliver, as the case may be, cash, shares of our common stock, or a 
combination of cash and shares of our common stock with respect to the remainder, if any, of our conversion obligation 
in excess of the aggregate principal amount of the Convertible Notes being converted. If we elect to settle the remainder, 
if any, of our conversion obligation in excess of the aggregate principal amount of the Convertible Notes being 
converted in shares of our common stock or a combination of cash and shares of our common stock, that action will 
dilute the ownership interest of our stockholders. Additionally, any sales in the public market of our 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 could be used to satisfy short positions, and the anticipated conversion into shares of our common stock 
could depress the price of our common stock. 
The hedges and warrants in our own common stock may adversely affect the common stock’s trading price. 
In September 2023, we entered into hedge and warrant transactions on our own common stock. These contracts 
are expected to reduce the potential dilution to our common stock upon any conversion of the Convertible Notes and/or 
offset any cash payments we are required to make in excess of the principal amount. The warrants could separately have 
a dilutive effect on our common stock to the extent that the market price per share of our common stock exceeds the 
exercise price. 
In addition, the counterparties or their affiliates may modify their hedge positions by entering into or unwinding 
various derivatives with respect to our common stock and sell our common stock prior to the maturity of the Convertible 
Notes (and are likely to do so in connection with any conversion or redemption). This activity could cause fluctuations in 
the market price of our common stock. 
 
 

25 
We are subject to counterparty default risk with respect to the Note Hedges. 
The counterparties are financial institutions, and we are subject to the risk that any or all of them might default. 
Our exposure is not secured by any collateral. If a counterparty becomes subject to insolvency proceedings, we will 
become an unsecured creditor. Our exposure will depend on many factors but, generally, an increase in our exposure will 
correlate to an increase in the market price and in the volatility of our common stock. In addition, counterparties may not 
be financially stable or viable. Upon a default by a counterparty, we may suffer adverse tax consequences and more 
dilution than we currently anticipate with respect to our common stock.  
Risks Relating to Ownership of Our Common Stock 
The market price of our common stock has fluctuated and may continue to fluctuate for reasons over which we have 
no control. 
The stock market has from time to time experienced, and is likely to continue to experience, extreme price and 
volume fluctuations. Prices of securities of technology companies are especially volatile and have often fluctuated for 
reasons that are unrelated to their operating performance. In the past, companies that have experienced volatility in the 
market price of their stock have been the subject of securities class action litigation. If we were the subject of securities 
class action litigation, it could result in substantial costs and a diversion of management’s attention and resources. 
We may not pay dividends on our common stock. 
Holders of our common stock are only entitled to receive dividends when and if they are declared by our Board 
of Directors. Our Credit Agreement restricts our ability to pay dividends on our capital stock under certain 
circumstances. Although we have declared cash dividends on our common stock since 2021, we are not required to do 
so, and we may reduce or eliminate our cash dividend in the future. This could adversely affect the market price of our 
common stock. For information on our Credit Agreement, see Note 18. Long-Term Debt and Note 7. Derivative 
Financial Instruments in Part II, Item 8 “Financial Statements and Supplementary Data.” 
Our operating results are subject to fluctuations, and if we fail to meet the expectations of securities analysts or 
investors, our share price may decrease significantly. 
Our annual and quarterly results may vary significantly depending on various factors, many of which are 
beyond our control. Because our operating expenses are based on anticipated revenue levels, our revenue cycle for 
development work is relatively long, and a high percentage of our expenses are fixed for the short term, a small variation 
in the timing of recognition of revenue can cause significant variations in operating results from period to period. If our 
earnings do not meet the expectations of securities analysts or investors, the price of our stock could decline.

ITEM 1C.         CYBERSECURITY 
Cybersecurity Risk Management and Assessment 
Advanced Energy understands the importance of managing risks from cybersecurity threats and maintains a 
comprehensive cybersecurity program developed with reference to the National Institute of Standards and Technology 
(“NIST”) cybersecurity framework. Our cybersecurity program includes administrative, organizational, technical, and 
physical safeguards reasonably designed to protect the confidentiality, integrity, and availability of our data. We devote 
significant resources to network, operations, and product security, data encryption, business continuity/disaster recovery, 
vulnerability management, event monitoring and incident response, and other measures to protect our systems and data 
from unauthorized external access or internal misuse, including, but not limited to, the following: 
• 
Operational Security. Access to our systems is restricted to those who require access in accordance with the 
principle of least privilege. We also conduct background checks for our employees where permitted by 
local law, require signed confidentiality agreements and acceptable use agreements, and follow 
termination/access removal processes. 
• 
Employee Training. We provide all employees with annual training on information security, data 
protection, and relevant Company policies so that they are empowered to identify cybersecurity risks and 
take action. To further enhance awareness and responsiveness to potential threats, we also conduct regular 
phishing simulations and email communications on cybersecurity trends awareness throughout the year.  
• 
Third Party Assessment. We engage independent third party consultants to review the effectiveness and 
maturity of our cybersecurity program.  
• 
Incident Response Plan. We maintain an incident response plan to respond to and mitigate the effects of an 
information security incident. The plan provides for the formation of a multi-functional incident response 
team led by the Chief Information Officer (“CIO”) and comprised of IT, legal, corporate communications, 
internal audit, operational personnel, and members of the Board of Directors.  
• 
Global Recovery. We have developed global cyber and disaster recovery processes for our information 
technology systems and critical information assets to preserve business continuity in the event of a 
cybersecurity incident. 
• 
Third Parties. We have an assessment and audit process for third party vendors. Prior to granting key 
vendor access to our systems or data, we conduct pre-engagement diligence to ensure that each of our third 
party vendors involved in processing sensitive data have reasonable cybersecurity processes and 
procedures in place. We also have contractual provisions with key vendors for prompt notification of 
material cybersecurity incidents.  
• 
Insurance. We maintain cyber insurance coverage to mitigate the risk of losses from a cybersecurity 
incident. 
• 
Risk Monitoring. Management and our Board monitor cybersecurity and data protection developments, 
including new or forthcoming changes to the legislative and regulatory landscape as well as Advanced 
Energy’s cybersecurity processes, investments, and actions as described below. 
Cybersecurity risk is a component of Advanced Energy’s broader risk management program and managed at 
the highest levels of the Company, starting with Advanced Energy’s CIO, who meets with the Chief Executive Officer 
and other members of executive management regularly to discuss issues, assess risks, and coordinate Company-wide 
cybersecurity initiatives. Our CIO leads a dedicated cybersecurity technical team that manages, monitors, and enforces 
compliance with the cybersecurity program.  
Although we have experienced non-material information security incidents from time to time in the past, in the 
last three years, we have not experienced any material cybersecurity incidents, nor has any incident had a material 
impact on our operations or financial condition. For a discussion of how risks from cybersecurity threats are reasonably 
likely to affect us, including our business strategy, results of operations, or financial condition, please see “If our 
information security measures are breached, disrupted, or fail, we may incur significant legal and financial exposure and 
liabilities” under the heading Part I, Item 1A “Risk Factors”.  

27 
Cybersecurity Governance 
Pursuant to its charter, the Audit and Finance Committee of our Board of Directors is principally responsible 
for oversight of managements’ actions to monitor and control cybersecurity risk exposure. The CIO routinely reports to 
the Audit and Finance Committee on enterprise cybersecurity matters, including, as appropriate, information security 
strategy, policies, and procedures, status of cybersecurity initiatives, results of third party assessments, emerging 
cybersecurity threats and risks, steps taken to mitigate such threats and risks, and cybersecurity developments and trends. 
The Audit and Finance Committee reports to the full Board and, if warranted, coordinates with the Board to address 
material risks. In addition, two members of the Board have been delegated authority to serve as initial points of contact 
for the Board in the event of a severe information security incident. The full Board receives a cybersecurity briefing 
from the CIO annually. 
As discussed above, our cybersecurity risk management and strategy are led by our CIO, who has extensive 
leadership experience with enterprise information technology in the manufacturing and telecom industries, where he has 
held various executive roles in which he developed and executed IT strategy, including cybersecurity programs, helped 
achieve and maintain Sarbanes-Oxley compliance, and brought companies into compliance with ISO 27001, among 
other things.

adjustments based on these assessments. 
ITEM 3.            LEGAL PROCEEDINGS 
We are involved in disputes and legal actions arising in the normal course of our business. Although it is not 
possible to predict the outcome of these matters, we believe that the results of these proceedings will not have a material 
adverse effect on our financial condition, results of operations, or liquidity. For further information see Note 17.

PART II 
ITEM 5.            MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER 
MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES 
Market Information and Dividends 
Our common stock is listed on the NASDAQ Global Select Market under the symbol “AEIS.” On January 31, 
2025, the number of common stockholders of record was 196. This does not include stockholders whose shares are held 
in “street name” through brokers or other nominees.  
In each of the four quarters in 2024, we paid quarterly cash dividends of $0.10 per share, totaling $15.4 million 
for the full year. We currently anticipate that a quarterly cash dividend of $0.10 per share will continue to be paid on a 
quarterly basis, although the declaration of any future cash dividend is at the discretion of the Board and will depend on 
our financial condition, results of operations, capital requirements, business conditions, and other factors.

To repurchase shares of our common stock, we periodically enter into share repurchase agreements, open 
market transactions, and/or other transactions in accordance with applicable federal securities laws. Before repurchasing 
our shares, we consider the market price of our common stock, the nature of other investment opportunities, available 
liquidity, cash flows from operations, general business and economic conditions, and other relevant factors.  
 
We did not repurchase any shares during the fourth quarter of 2024. At December 31, 2024, the remaining 
amount authorized by our Board for future share repurchases was $197.4 million with no time limitation.

ITEM 7.            MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
RESULTS OF OPERATIONS 
Certain statements set forth below under this caption constitute forward-looking statements. See “Special 
Note Regarding Forward-Looking Statements” in this annual report on Form 10 - K for additional factors relating to such 
statements and see “Risk Factors” in Part I, Item 1A for a discussion of certain risks applicable to our business, financial 
condition, and results of operations. 
The following section discusses our results of operations for 2024 and 2023 and year-to-year comparisons 
between those periods. 
Company Overview 
Advanced Energy provides highly engineered, critical, precision power conversion, measurement, and control 
solutions to our global customers. We design, manufacture, sell and support precision power products that transform, 
refine, and modify the raw electrical power coming from either the utility or the building facility and convert it into 
various types of highly controllable, usable power that is predictable, repeatable, and customizable to meet the necessary 
requirements for powering a wide range of complex equipment. Many of our products enable customers to reduce or 
optimize their energy consumption through increased power conversion efficiency, power density, power coupling, and 
process control across a wide range of applications. 
We are organized on a global, functional basis and operate as a single segment of power electronics conversion 
products. Within this segment, our products are sold into the Semiconductor Equipment, Industrial and Medical, Data 
Center Computing, and Telecom and Networking markets. 
On June 20, 2024, we acquired Airity Technologies, Inc. (“Airity”). This acquisition added high voltage power 
conversion technologies and products, broadening our range of targeted applications within the Semiconductor 
Equipment and Industrial and Medical markets. See Note 2. Acquisition in Part II, Item 8 “Financial Statements and 
Supplementary Data.” 
Business Environment and Trends 
2024 Summary Results and Key Activities 
For the year ended December 31, 2024, our revenue was $1,482.0 million, representing a decline of 10.5% as 
compared to 2023. The decline was attributable to lower revenue from our Industrial and Medical and Telecom and 
Networking markets due to customer inventory rebalancing, resulting in a lower demand environment. These declines 
were partially offset by higher revenues in the Semiconductor Equipment market, from the 2023 trough level, and 
growing AI-related demand in the Data Center Computing market. For more details on the trends in our end markets, see 
“End Markets Summary and Trends” elsewhere in this Item 7. 
In 2024, we reported higher operating expenses of $492.7 million, an increase of $14.0 million primarily 
attributable to higher stock-based compensation expense, higher research and development (“R&D”) program costs, 
higher restructuring charges from initiatives focused on optimizing manufacturing and support operations, partially 
offset by a general workforce reduction to align to our revenue levels. The restructuring actions should largely be 
completed in 2026 and are expected to enable a more efficient and cost-effective operating structure.  
In the third quarter of 2024, we approved further manufacturing consolidation initiatives, including the closure 
of our Zhongshan, China manufacturing facility. In connection with the 2024 Plan, we recorded a $29.6 million charge 
primarily associated with expected employment-related charges and facility exit costs. See Note 12. Restructuring, Asset 
Impairments, and Other Charges in Part II, Item 8 “Financial Statements and Supplementary Data.” 

31 
In the third quarter of 2024, we entered into an amendment to the Credit Agreement to increase the capacity on 
the Revolving Facility from $200.0 million to $600.0 million. This amendment was in connection with the concurrent 
prepayment, using existing cash on hand, of the full $345.0 million outstanding principal balance under our Term Loan 
Facility. See Note 18. Long-Term Debt in Part II, Item 8 “Financial Statements and Supplementary Data” and Liquidity 
and Capital Resources below. 
During 2024, we continued progress on a new factory near Bangkok, Thailand, which we expect to be 
operational in 2026. 
End Markets Summary and Trends 
The demand environment in each of our markets is impacted by macroeconomic conditions, various market 
trends, customer buying patterns, design wins, and other factors. Although we are currently experiencing a lower 
demand environment in certain markets, we continue to believe that the long-term market growth drivers support our 
long-term strategy, research and development efforts, and capital investments. However, in the short-term it is unclear 
how certain macroeconomic conditions, including the effect of higher interest rates impacting end customers’ capital 
investment, the timing of inventory digestion, and customer buying patterns, will affect customer demand and our 
revenue. 
Semiconductor Equipment Market 
The Semiconductor Equipment market appears to be slowly recovering from a cyclical downturn, which 
bottomed in 2023. Demand improved in 2024, but a number of external factors continue to limit the market recovery, 
including unfavorable macroeconomic conditions, prolonged weak demand for consumer electronics, low fab utilization, 
and U.S. export restrictions to China.  
We continue to believe the long-term growth drivers will support cyclical growth for this market. Growth 
drivers include more manufacturing capacity needed to support increasing demand for semiconductor devices, increasing 
etch and deposition process steps with new technology inflections, and the transition to advanced technology nodes 
requiring higher content of advanced power solutions per tool. In addition, we believe our investment in new products 
can enable market share gains resulting in higher than market growth.  
Industrial and Medical Market 
Beginning in the second half of 2023, the impact of weaker macroeconomic conditions started to lower demand 
for our products in the Industrial and Medical market. In addition, in the previous two years, many customers built 
inventories of our products following the supply chain disruption and extended lead times. As lead times normalized in 
2024, customers rebalanced their elevated inventory levels resulting in further decline in revenue. We expect these 
factors will continue to limit our revenue in the near term but believe that growth will return to this market after 
customer inventories return to normal levels and end markets recover.  
Data Center Computing Market 
Revenue in the Data Center Computing market was weak in the first quarter of 2024 driven by reduced 
investments by our hyperscale customers, lower demand for enterprise systems, and the timing of large customer orders. 
Starting in the second quarter of 2024, demand rebounded driven by accelerated investments in AI and customers 
starting to ramp new generations of high power solutions, resulting in revenue growth in 2024. We expect these factors 
will continue to support strong demand for the next few quarters.  
Telecom and Networking Market 
In 2023, improved supply of critical components drove a meaningful increase in revenue, which more than 
offset weakening market conditions in the Telecom and Networking market. End demand further weakened during 2024. 
In addition, customers rebalanced their elevated inventory levels as lead times normalized, resulting in a further decline 
in our revenue. We expect the current market conditions to continue for several quarters.

Results of Continuing Operations 
The analysis presented below is organized to provide the information we believe will be helpful for 
understanding of our historical performance and relevant trends going forward and should be read in conjunction with 
our consolidated financial statements, including the notes thereto, in Part II, Item 8 “Financial Statements and 
Supplementary Data” of this annual report on Form 10 - K. Also included in the following analysis are measures that are 
not in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). A 
reconciliation of the non-GAAP measures to U.S. GAAP is provided below.

Total revenue decreased from the same period in the prior year due primarily to lower end demand and 
customer inventory rebalancing, resulting in lower demand in our Industrial and Medical and Telecom and Networking 
markets. The Semiconductor Equipment market modestly recovered from the cyclical trough in 2023, and revenue in the 
Data Center Computing market grew as hyperscale customers increased investments in AI.  
Revenue by Market  
Sales in the Semiconductor Equipment market increased $48.8 million, or 6.6%, to $792.6 million, as compared 
to $743.8 million in the prior year. The increase was primarily due to improved demand as we emerge from the cyclical 
trough in 2023. 
Sales in the Industrial and Medical market decreased $158.3 million, or 33.4%, to $316.2 million, as compared 
to $474.4 million in the prior year. After a record year in 2023, the decrease was primarily due to lower end demand and 
customers working down their elevated inventories on shortened lead times following the supply chain disruption.  
Sales in the Data Center Computing market increased $34.3 million, or 13.7%, to $284.2 million, as compared 
to $249.9 million in the prior year. The increase was due to accelerated hyperscale investments in AI and growing 
adoption of next generation high power solutions.  
Sales in the Telecom and Networking market decreased $98.6 million, or 52.5%, to $89.1 million as compared 
to $187.7 million in the prior year. The decrease was due to the prior year benefiting from the improved supply of 
critical components. This enabled fulfillment of outstanding orders in 2023, which did not continue in 2024. In addition, 
we experienced a slow demand environment and inventory rebalancing at many of our customers, which we expect to 
continue.

Research and Development 
Research and development expenses increased $9.4 million to $211.8 million, as compared to $202.4 million in 
the prior year. The increase is related to higher stock-based compensation expense as well as higher program and 
materials costs compared to the prior year. This was partially offset by lower variable compensation.  
Selling, General and Administrative 
Selling, general and administrative expenses increased $3.5 million to $224.5 million, as compared to $221.0 
million in the prior year. The increase is primarily driven by higher stock-based compensation expense, partially offset 
by actions taken to control costs, including headcount reduction and lower variable compensation. 
Amortization of Intangible Assets 
Amortization expense decreased $2.2 million to $26.0 million, as compared to $28.3 million in the prior year. 
Certain intangible assets reached the end of their estimated useful life in the current year. This was partially offset by 
amortization of intangible assets acquired in the Airity acquisition. For additional information, see Note 2. Acquisition 
and Note 11. Intangible Assets and Goodwill in Part II, Item 8 “Financial Statements and Supplementary Data.” 
 
 

35 
Restructuring, Asset Impairments and Other Charges 
In the third quarter of 2024, we approved further manufacturing consolidation initiatives, including the closure 
of our Zhongshan, China manufacturing facility. In connection with the 2024 Plan, we recorded a $29.6 million charge 
primarily associated with expected employment-related charges and facility exit costs. The amounts incurred as a result 
of the approved actions are estimates and actual results may differ, which could result in incremental restructuring 
charges in future periods. We anticipate the 2024 Plan will be substantially completed by the end of second quarter of 
2025, with final activities expected to conclude in 2026.  
For additional information about this and prior year restructuring plans, see Note 12. Restructuring, Asset 
Impairments, and Other Charges in Part II, Item 8 “Financial Statements and Supplementary Data.” 
 
Interest Income, Interest Expense, and Other Income (Expense), net 
We experienced an increase in interest income on higher cash balances, due in part to proceeds from the 
issuance of the Convertible Notes in the third quarter of 2023, our ability to concentrate cash in investment accounts, and 
higher short term market interest rates. 
Interest expense increased due to interest associated with the Convertible Notes and a higher interest rate on the 
portion of our Term Loan Facility subject to a variable interest rate. We prepaid in full the Term Loan Facility on 
September 9, 2024, and the interest rate swap contracts expired on September 10, 2024. Should we have future 
borrowings under our Term Loan Facility or Revolving Facility, those borrowings would be subject to a variable rate.  
Other expense, net was $2.0 million in 2024, as compared to $1.8 million of expense in the prior year. Other 
expense, net consists primarily of foreign exchange gains and losses and other miscellaneous items. We had unrealized 
foreign exchange losses during the year 2024 compared to unrealized gains in the prior year. Additionally, in 2024, we 
incurred costs associated with foreign currency translation adjustments related to liquidated foreign operations and debt 
discount and fees associated with our Term Loan Facility prepayment. There were no such costs during the same periods 
in the prior year. 
See Note 18. Long-Term Debt in Part II, Item 8 “Financial Statements and Supplementary Data” for 
information regarding our debt.

Effective tax rate 
 
  
 (7.5)%  
 (6.8)% 
 
Our effective tax rates differ from the U.S. federal statutory rate of 21% for the years ended December 31, 2024 
and 2023, primarily due to the intercompany transfer of intellectual property among certain of our subsidiaries in 2024 
and a valuation allowance release in 2023. Additionally, both 2024 and 2023 included the benefit of earnings in foreign 
jurisdictions which are subject to lower tax rates, as well as tax credits, partially offset by net U.S. tax on foreign 
operations. 
Our future effective income tax rate depends on various factors, such as changes in tax laws, regulations, 
accounting principles, or interpretations thereof, and the geographic composition of our pre-tax income. We carefully 
monitor these factors and adjust our effective income tax rate accordingly. 
As of January 1, 2024, the Pillar II minimum global effective tax rate of 15% enacted by the Organization for 
Economic Cooperation and Development (“OECD”) was effectuated. More than 140 countries agreed to enact the 
Pillar II global minimum tax. However, the timing of the implementation for each country varies. For the year ended 
December 31, 2024, we included an estimate of global minimum tax liability as a result of those countries where we 
conduct business that have adopted Pillar II. As countries continue to make revisions to their legislation and release 
additional guidance with respect to the global minimum tax, we continue to determine any potential impact in the 
countries in which we operate. The impact of these changes may have a material impact on our cash tax expense and tax 
rate. 
Non-GAAP Results 
Management uses non-GAAP operating income and non-GAAP earnings per share (“EPS”) to evaluate 
business performance without the impacts of certain non-cash charges and other charges which are not part of our usual 
operations. We use these non-GAAP measures to assess performance against business objectives, and make business 
decisions, including developing budgets and forecasting future periods. In addition, management’s incentive plans 
include these non-GAAP measures as criteria for achievements. These non-GAAP measures are not prepared in 
accordance with U.S. GAAP and may differ from non-GAAP methods of accounting and reporting used by other 
companies. However, we believe these non-GAAP measures provide additional information that enables readers to 
evaluate our business from the perspective of management. The presentation of this additional information should not be 
considered a substitute for results prepared in accordance with U.S. GAAP. 
The non-GAAP results presented below exclude the impact of non-cash related charges, such as stock-based 
compensation, amortization of intangible assets, and long-term unrealized foreign exchange gains and losses. In 
addition, we exclude discontinued operations and other non-recurring items such as acquisition-related costs, facility 
expansion and related costs, and restructuring expenses, as they are not indicative of future performance. The tax effect 
of our non-GAAP adjustments represents the anticipated annual tax rate applied to each non-GAAP adjustment after 
consideration of their respective book and tax treatments. Finally, non-GAAP results exclude one-time tax benefits and 
losses associated with changes in our legal entity structure or ownership of certain assets.

Liquidity and Capital Resources 
Liquidity 
Adequate liquidity and cash generation are important to the execution of our strategic initiatives. Our ability to 
fund our operations, acquisitions, capital expenditures, and product development efforts may depend on our ability to 
generate cash from operating activities, which is subject to future operating performance, as well as general economic, 
financial, competitive, legislative, regulatory, and other conditions, some of which may be beyond our control. Our 
primary sources of liquidity continue to be our available cash, cash generated from operations, and available borrowing 
capacity under the Revolving Facility (refer to Note 18. Long-Term Debt in Part II, Item 8 “Financial Statements and 
Supplementary Data”).  
As of December 31, 2024, our cash and cash equivalents totaled $722.1 million, and our available funding 
under our Revolving Facility is $600.0 million. Additionally, we generated $132.9 million of cash flow from continuing 
operations in 2024. We believe our sources of liquidity will be adequate to meet anticipated debt service, share 
repurchase programs, and dividends. During the ordinary course of business, we evaluate our cash requirements and, if 
necessary, adjust our expenditures to reflect the current market conditions and our projected revenue and demand. Our 
capital expenditures are primarily directed towards manufacturing and operations and can materially influence our 
available cash for other initiatives. 
In addition, we may seek additional debt or equity financing from time to time; however, such additional 
financing may not be available on acceptable terms, if at all. 
Debt 
On September 9, 2024, we used existing cash on hand to prepay the full $345.0 million outstanding principal 
balance under our Term Loan Facility. On the same date, we entered into an additional amendment to the Credit 
Agreement to increase the capacity on the Revolving Facility from $200.0 million to $600.0 million.  
As of December 31, 2024, our only outstanding debt is the $575.0 million Convertible Notes, which mature on 
September 15, 2028 and carry a 2.5% interest rate. 
The interest rate swap contracts previously entered into related to the Term Loan Facility expired on 
September 10, 2024. Should we have future borrowings under our Term Loan Facility or Revolving Facility, those 
borrowings would be subject to a variable rate. 
As of December 31, 2024, no amounts were outstanding under the Revolving Facility, and we had $600.0 
million in available funding.  
In addition to the available capacity on the Revolving Facility, prior to the maturity date of the Credit 
Agreement, we may request an increase to the financing commitments in either the Term Loan Facility or Revolving 
Facility by an aggregate amount not to exceed $250.0 million. Any requested increase is subject to lender approval. 
For more information see Note 18. Long-Term Debt in Part II, Item 8 “Financial Statements and Supplementary 
Data.” 
Dividends 
During 2024, we paid quarterly cash dividends of $0.10 per share, totaling $15.4 million. We currently 
anticipate that a cash dividend of $0.10 per share will continue to be paid on a quarterly basis, although the declaration 
of any future cash dividend is at the discretion of the Board of Directors and will depend on our financial condition, 
results of operations, capital requirements, business conditions, and other factors.

Share Repurchases  
To repurchase shares of our common stock, we periodically enter into share repurchase agreements. The 
following table summarizes these repurchases:

Net Cash From Operating Activities 
Net cash from operating activities from continuing operations was $132.9 million, a decrease of $80.0 million, 
compared to $212.9 million in the prior year. The decrease was primarily due to lower net income from continuing 
operations, primarily due to a decline in revenue. Additionally, during the current year, we had a significant use of cash 
for inventories due to a strategic inventory buildup. In addition, we had net cash usage related to accounts payable, 
accrued expenses, restructuring payments, and other liabilities. 
Net Cash From Investing Activities  
Net cash used in investing activities in 2024 was $73.5 million, an increase of $8.7 million, compared to $64.8 
million in the prior year. The increase was primarily due to our acquisition of Airity for $13.8 million and continued 
capital investments in our Mexico and Thailand manufacturing facilities. 
Net Cash From Financing Activities 
Net cash used in financing activities in 2024 was $377.1 million, compared to a cash inflow of $445.7 million 
in the prior year. In 2024, we used existing cash on hand to make payments towards our Term Loan Facility for $355.0 
million, including $10.0 million in principal payment made in the first half of the year and the September prepayment of 
the remaining $345.0 million outstanding principal balance, and repurchased common stock for $1.8 million. We do not 
have any scheduled debt maturities in the next twelve months. 

40 
During 2023, we received $561.1 million net proceeds from the issuance of long-term debt from our 
Convertible Note. In conjunction with the Convertible Note issuance, we also received $74.9 million proceeds from sale 
of warrants and made a $115.0 million payment for purchase of note hedges. We also repurchased $40.1 million of our 
common stock.  
Critical Accounting Estimates 
The preparation of consolidated financial statements and related disclosures in conformity with U.S. GAAP 
requires us to make judgments, assumptions, and estimates that affect the amounts reported. Note 1. Summary of 
Operations and Significant Accounting Policies and Estimates in Part II, Item 8 “Financial Statements and 
Supplementary Data” describes the significant accounting policies used in the preparation of our consolidated financial 
statements. The accounting positions described below are significantly affected by critical accounting estimates. Such 
accounting policies and estimates require significant judgments and assumptions to be used in the preparation of the 
consolidated financial statements and actual results could differ materially from the amounts reported based on 
variability in factors affecting these estimates. 
Inventories 
We value inventories at the lower of cost or net realizable value, computed on a first-in, first-out basis. General 
market conditions, as well as our design activities, can cause certain products to become obsolete and we adjust our 
inventory carrying value for estimated excess and obsolescence equal to the difference between the cost of inventory and 
the estimated net realizable value based on projected end-user demand, which is determined by considering historical 
usage, customer orders and forecast, and qualitative considerations such as market and economic conditions. The 
determination of projected end-user demand requires the use of estimates and assumptions related to projected unit sales 
for each product. Demand for our products can fluctuate significantly. A significant decrease in demand could result in 
an increase in the charges for excess inventory quantities on hand.  
Income Taxes 
We follow the liability method of accounting for income taxes under which deferred tax assets and liabilities 
are recognized for future tax consequences. A deferred tax asset or liability is computed for both the expected future 
impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future 
tax benefit to be derived from tax loss and tax credit carryforwards. Tax rate changes are reflected in the period such 
changes are enacted.  
We assess the recoverability of our net deferred tax assets and the need for a valuation allowance on a quarterly 
basis. Our assessment includes several factors, including historical results and taxable income projections for each 
jurisdiction. The ultimate realization of deferred income tax assets is dependent on the generation of taxable income in 
appropriate jurisdictions during the periods in which those temporary differences are deductible. We consider the 
scheduled reversal of deferred income tax liabilities, projected future taxable income, and tax planning strategies in 
determining the amount of the valuation allowance. Based on the level of historical taxable income and projections for 
future taxable income over the periods in which the deferred income tax assets are deductible, we determine if we will 
more likely than not realize the benefits of these deductible differences.  
Due to uncertainties in any tax audit outcome, our estimates of the ultimate settlement of our unrecognized tax 
positions may change and the actual tax benefits may differ significantly from the estimates. We regularly assess the 
likelihood of favorable or unfavorable outcomes resulting from these examinations to determine the adequacy of our 
provision for income taxes. This evaluation is based on factors including, but not limited to, changes in facts or 
circumstances, changes in tax law, effectively settled issues under audit, and new audit activity. 
For more details see Note 4. Income Taxes in Part II, Item 8 “Financial Statements and Supplementary Data.” 

41 
Business Combinations 
We record the assets acquired and liabilities assumed in a business combination at their acquisition date fair 
values. Fair values of assets acquired, and liabilities assumed are based upon available information and may involve 
engaging an independent third party to perform an appraisal. Estimating fair values can be complex and subject to 
significant business judgment. We must also identify and include in the allocation all acquired tangible and intangible 
assets that meet certain criteria, including assets that were not previously recorded by the acquired entity. The estimates 
most commonly involve intangible assets. The excess of the purchase price over the net fair value of acquired assets and 
assumed liabilities is recorded as goodwill, which is not amortized but instead is evaluated for impairment at least 
annually. Pursuant to U.S. GAAP, an entity is allowed a reasonable period of time (not to exceed one year) to obtain the 
information necessary to identify and measure the fair value of the assets acquired and liabilities assumed in a business 
combination. 
Off-Balance Sheet Arrangements 
As of December 31, 2024, we did not have any off-balance sheet arrangements pursuant to Regulation S-K. 
Contractual Obligations 
In the normal course of business, we enter into contracts and commitments that obligate us to make payments in 
the future. Information regarding our obligations relating to income taxes, lease obligations, pension liabilities, and debt 
is provided in Note 4. Income Taxes, Note 14. Leases, Note 15. Employee Retirement Plans and Postretirement Benefits, 
and Note 18. Long-Term Debt, respectively, in Part II, Item 8 “Financial Statements and Supplementary Data.” 
Recent Accounting Pronouncements 
From time to time, updates to the Accounting Standards Codification are communicated through issuance of an 
Accounting Standards Update. Unless otherwise discussed, we believe that the impact of recently issued guidance, 
whether adopted or to be adopted in the future, is not expected to have a material impact on our consolidated financial 
statements upon adoption. 
To understand the impact of recently issued guidance from the Financial Accounting Standards Board 
(“FASB”) or other standards setting bodies, whether adopted or to be adopted, please review the information provided in 
Note 1. Summary of Operations and Significant Accounting Policies and Estimates in Part II, Item 8 “Financial 
Statements and Supplementary Data.” 
 
ITEM 7A.         QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 
Market Risk and Risk Management 
In the normal course of business, we have exposures to interest rate risk from our investments and Credit 
Agreement. We also have exposure to foreign exchange rate risk related to our foreign operations and foreign currency 
transactions. 
Foreign Currency Exchange Rate Risk 
We are impacted by changes in foreign currency exchange rates through revenue and purchasing transactions 
when we sell products and purchase materials in currencies different from the currency in which product and 
manufacturing costs were incurred. Our reported financial results of operations, including the reported value of our 
assets and liabilities, are also impacted by changes in foreign currency exchange rates. Assets and liabilities of 
substantially all our subsidiaries outside the U.S. are translated at period end rates of exchange for each reporting period. 
Operating results and cash flow statements are translated at average rates of exchange during each reporting period. 
Although these translation changes have no immediate cash impact, the translation changes may impact future 
borrowing capacity, and overall value of our net assets.  

42 
The functional currencies of our worldwide facilities primarily include the United States Dollar, Euro, South 
Korean Won, New Taiwan Dollar, Japanese Yen, Pound Sterling, and Chinese Yuan. We are subject to risks associated 
with revenue and purchasing activities and costs to operate that are denominated in currencies other than our functional 
currencies, such as the Singapore Dollar, Malaysian Ringgit, Mexican Peso, Philippine Peso, and Thai Baht. 
Historically, the impact of changes to these particular exchange rates has not been material to our operating results.  
From time to time, we may enter into foreign currency exchange rate contracts to hedge against changes in 
foreign currency exchange rates on assets and liabilities expected to be settled at a future date, including foreign 
currency, which may be required for a potential foreign acquisition. Market risk arises from the potential adverse effects 
on the value of derivative instruments that result from a change in foreign currency exchange rates. We may enter into 
foreign currency forward contracts to manage the exchange rate risk associated with intercompany debt denominated in 
nonfunctional currencies. We minimize our market risk applicable to foreign currency exchange rate contracts by 
establishing and monitoring parameters that limit the types and degree of our derivative contract instruments. We enter 
into derivative contract instruments for risk management purposes only. We do not enter into or issue derivatives for 
trading or speculative purposes. 
Interest Rate Risk 
At the present time, a change in interest rates does not have an impact upon our future earnings and cash flow 
because our only outstanding debt is the Convertible Notes, which carry a fixed 2.5% interest rate. However, increases in 
interest rates could impact the decision to borrow under our Credit Agreement and our ability to refinance existing 
maturities or acquire additional debt on favorable terms. 
For more information see Note 18. Long-Term Debt in Part II, Item 8 “Financial Statements and Supplementary 
Data.”

Report of Independent Registered Public Accounting Firm 
To the Stockholders and the Board of Directors of Advanced Energy Industries, Inc. 
Opinion on the Financial Statements 
We have audited the accompanying consolidated balance sheets of Advanced Energy Industries, Inc. (the 
Company) as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive 
income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2024, and the 
related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated 
financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2024 
and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 
2024, in conformity with U.S. generally accepted accounting principles. 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2024, based on 
criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (2013 framework), and our report dated February 18, 2025 expressed an unqualified opinion 
thereon. 
Basis for Opinion 
These financial statements are the responsibility of the Company's management. Our responsibility is to express 
an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with 
the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal 
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan 
and perform the audit to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material 
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those 
risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made 
by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits 
provide a reasonable basis for our opinion. 
Critical Audit Matter 
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.

 Inventory valuation  
Description of the 
Matter 
 As more fully described in Notes 1 and 9 to the consolidated financial statements, the 
Company has inventories with a carrying value of $360.4 million as of December 31, 2024. 
The Company adjusts its inventory carrying value for estimated excess or obsolescence equal 
to the difference between the cost of inventory and the estimated net realizable value based on 
projected customer demand, which is determined by considering historical usage, customer 
orders and forecast, and qualitative considerations such as market and economic conditions. 
Auditing management’s inventory valuation was complex and involved judgment because a 
critical factor in determining excess and obsolete inventory requires management to determine 
projected customer demand, which could be impacted by future market and economic 
conditions. 
How We Addressed the 
Matter in Our Audit 
 We obtained an understanding, evaluated the design, and tested the operating effectiveness of 
internal controls related to the Company’s process for evaluating inventory valuation inclusive 
of controls related to the development of and management’s review of the underlying data, 
including historical usage and the estimation of projected customer demand. 
We evaluated certain inventories for excess or obsolescence by testing key inputs, including 
historical usage and projected customer demand, and by testing the completeness and 
accuracy of the underlying data supporting management’s inventory valuation assessment. 
Specifically, we compared the Company’s projected customer demand to historical sales and 
inventory usage. We assessed historical trends of management’s estimates and performed 
analyses to evaluate management’s excess and obsolete inventory estimates and underlying 
assumptions. We also performed a retrospective review of the prior year valuation 
assumptions, including inventory write-off history.

Report of Independent Registered Public Accounting Firm 
To the Stockholders and the Board of Directors of Advanced Energy Industries, Inc. 
Opinion on Internal Control Over Financial Reporting 
We have audited Advanced Energy Industries, Inc.’s internal control over financial reporting as of 
December 31, 2024, based on criteria established in Internal Control—Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, 
Advanced Energy Industries, Inc. (the Company) maintained, in all material respects, effective internal control over 
financial reporting as of December 31, 2024, based on the COSO criteria. 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the 
related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of 
the three years in the period ended December 31, 2024, and the related notes and our report dated February 18, 2025 
expressed an unqualified opinion thereon. 
Basis for Opinion 
The Company’s management is responsible for maintaining effective internal control over financial reporting 
and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying 
Management’s Annual 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. 

47 
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.

ADVANCED ENERGY INDUSTRIES, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
 
53 
NOTE 1.           SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES AND 
ESTIMATES 
Advanced Energy Industries, Inc., a Delaware corporation, and its consolidated subsidiaries (“we,” “us,” “our,” 
“Advanced Energy,” or the “Company”) provides highly engineered, critical, precision power conversion, measurement, 
and control solutions to our global customers. We design, manufacture, sell and support precision power products that 
transform, refine, and modify the raw electrical power coming from either the utility or the building facility and convert 
it into various types of highly controllable, usable power that is predictable, repeatable, and customizable to meet the 
necessary requirements for powering a wide range of complex equipment. Many of our products enable customers to 
reduce or optimize their energy consumption through increased power conversion efficiency, power density, power 
coupling, and process control across a wide range of applications. 
In December 2015, we completed the wind down of engineering, manufacturing, and sales of our solar inverter 
product line. We have continuing involvement with regard to certain warranty obligations. Accordingly, the results of 
our inverter business are reflected as loss from discontinued operations, net of income taxes on our Consolidated 
Statements of Operations. 
Principles of Consolidation  
Our consolidated financial statements include the Company and its subsidiaries. All intercompany accounts and 
transactions have been eliminated. Our consolidated financial statements are stated in United States (“U.S.”) Dollars and 
have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”).  
Reclassifications 
We reclassified certain prior period amounts to conform to the current year presentation. Within the operating 
activities section of our Consolidated Statements of Cash Flows, we present activity associated with our operating leases 
separately in the caption “Operating lease right-of-use assets and operating lease liabilities, net.” Additionally, we 
separately present “Amortization and write-off of debt issuance costs and debt discount.” Previously the above activity 
was included within “Other liabilities and accrued expenses.” 
Use of Estimates in the Preparation of the Consolidated Financial Statements  
The preparation of our consolidated financial statements in conformity with U.S. GAAP requires us to make 
estimates, assumptions, and judgments that affect the reported amounts of assets and liabilities, the disclosure of 
contingent liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the 
reporting period. The significant estimates, assumptions, and judgments include, but are not limited to, excess and 
obsolete inventory, income taxes and other provisions, and acquisitions and asset valuation. 
Segment Information 
Our Chief Executive Officer (“CEO”) is the chief operating decision maker who reviews financial information 
on a consolidated basis for purposes of allocating resources and evaluating financial performance. Accordingly, we 
determined we operate in a single reporting segment – power electronics conversion products. Within this segment, our 
products are sold into the Semiconductor Equipment, Industrial and Medical, Data Center Computing, and Telecom and 
Networking markets.  
Our CEO assesses performance and decides how to allocate resources primarily based on consolidated net 
income, which is reported on our Consolidated Statements of Operations. Total assets on the Consolidated Balance 
Sheets represent our segment assets. 

ADVANCED ENERGY INDUSTRIES, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued)

Foreign Currency Translation 
The functional currency of certain of our foreign subsidiaries is the local currency. Assets and liabilities of these 
foreign subsidiaries are translated to the United States Dollar at prevailing exchange rates on the balance sheet date. 
Revenues and expenses are translated at the average exchange rates in effect for each period. Translation adjustments 
resulting from this process are reported as a separate component of other comprehensive income.  
For certain other subsidiaries, the functional currency is the U.S. Dollar. Foreign currency transactions are 
recorded based on exchange rates at the time such transactions arise. Subsequent changes in exchange rates for foreign 
currency denominated monetary assets and liabilities result in foreign currency transaction gains and losses, which are 
reflected as unrealized (based on period end remeasurement) or realized (upon settlement of the transactions) in other 
income (expense), net in our Consolidated Statements of Operations. 
Derivatives 
We use derivative financial instruments to manage risks associated with foreign currency. Unless we meet 
specific hedge accounting criteria, changes in the fair value of derivative financial instruments are recognized in the 
Consolidated Statements of Operations within other income (expense), net.  
Fair Value 
We value certain financial assets and liabilities using fair value measurements.  
U.S. GAAP for fair value establishes a hierarchy that prioritizes fair value measurements based on the types of 
inputs used for the various valuation techniques (market approach, income approach, and cost approach). Our financial 
assets and liabilities are measured using inputs from the three levels of the fair value hierarchy. The three levels of the 
hierarchy and the related inputs are as follows: 
• 
Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can 
access on the measurement date. 
• 
Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or 
liability, either directly or indirectly. 
• 
Level 3 — Unobservable inputs for the asset or liability. 
We categorize fair value measurements within the fair value hierarchy based upon the lowest level of the most 
significant inputs used to determine fair value. Our assessment of the significance of a particular input to the fair value 
measurement requires judgment and may affect the valuation of the fair value of assets and liabilities and their 
placement within the fair value hierarchy levels.

assets, and future inflation rates 
 
The carrying amounts of our cash and cash equivalents, accounts receivable, accounts payable and other current 
assets and liabilities approximate fair value as recorded due to the short-term nature of these instruments.  
Our non-financial assets, which primarily consist of property and equipment, operating lease right-of-use assets, 
goodwill, and other intangible assets, are not required to be carried at fair value on a recurring basis and are reported at 
carrying value. However, on a periodic basis or whenever events or changes in circumstances indicate that their carrying 
value may not be fully recoverable (and at least annually for goodwill), non-financial instruments are assessed for 
impairment and, if applicable, written down to and recorded at fair value. See Note 11. Intangible Assets and Goodwill 
for further discussion and presentation of these amounts. 
Cash and Cash Equivalents 
We consider all amounts on deposit with financial institutions and highly liquid investments with an original 
maturity of three months or less at the time of purchase to be cash equivalents. Cash and cash equivalents consist 
primarily of short-term money market instruments and demand deposits with insignificant interest rate risk.  
In some instances, we invest excess cash in money market funds not insured by the Federal Deposit Insurance 
Corporation. The investments in money market funds are on deposit with credit-worthy financial institutions and the 
funds are highly liquid. These investments are reported at fair value and included in cash and cash equivalents.  
We classify investments with stated maturities of greater than three months at time of purchase in other current 
assets on the Consolidated Balance Sheets.  
Concentrations of Credit Risk 
Financial instruments with potential credit risk include cash and cash equivalents and trade accounts receivable. 
To preserve capital and maintain liquidity, we invest with financial institutions we deem to be of high quality and sound 
financial condition. Our investments are in low-risk instruments, and we limit our credit exposure in any one institution 
or type of investment instrument based upon criteria, including creditworthiness.

Allowance for Credit Losses  
We evaluate collection risk and establish expected credit loss primarily through a combination of the following: 
continuous monitoring of customer credit, analysis of historical aging and credit loss experience, current economic 
conditions, and customer specific information.  
Our standard payment terms are net 30 days. Certain large volume customers have longer payment terms. 
Generally, we do not require collateral from customers. 
Inventories 
We value inventories at the lower of cost or net realizable value, computed on a first-in, first-out basis. General 
market conditions, as well as our design activities, can cause certain products to become obsolete and we adjust our 
inventory carrying value for estimated excess and obsolescence equal to the difference between the cost of inventory and 
the estimated net realizable value based on projected end-user demand, which is determined by considering historical 
usage, customer orders and forecast, and qualitative considerations such as market and economic conditions. The 
determination of projected end-user demand requires the use of estimates and assumptions related to projected unit sales 
for each product. Demand for our products can fluctuate significantly. A significant decrease in demand could result in 
an increase in the charges for excess inventory quantities on hand.  
Property and Equipment 
Property and equipment are stated at cost or estimated fair value if acquired in a business combination. We 
compute depreciation over the estimated useful lives using the straight-line method. Additions and improvements are 
capitalized, while maintenance and repairs are expensed as incurred. We evaluate the useful life and test for impairment 
whenever events or changes in circumstances indicate the carrying amount of an asset group containing the property and 
equipment may not be recoverable. 
When depreciable assets are retired, or otherwise disposed of, the cost and related accumulated depreciation are 
removed from the accounts, and any related gains or losses are included in other income (expense), net, in our 
Consolidated Statements of Operations. 
Internal-Use Software Development Costs 
We capitalize qualifying costs associated with software applications developed for internal use. We begin 
capitalization after meeting two criteria: (i) the preliminary project stage is completed and (ii) it is probable that the 
software will be completed and used for its intended function. We also capitalize costs related to specific upgrades and 
enhancements when it is probable the expenditures will result in significant additional functionality. We cease 
capitalization when the software is substantially complete and ready for its intended use, including the completion of all 
significant testing. 
Costs related to preliminary project activities, post-implementation operating activities, maintenance, and minor 
upgrades are expensed as incurred. 
We classify capitalized software development costs within property and equipment, net and other assets on the 
Consolidated Balance Sheets. These costs are amortized on a straight-line basis over the software’s estimated useful life. 
Amortization is included in both cost of revenue and operating expenses. We evaluate the useful life and test for 
impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. 

ADVANCED ENERGY INDUSTRIES, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued)

Leases 
We lease manufacturing and office space under non-cancelable operating leases. Some of these leases contain 
provisions for landlord funded leasehold improvements, which we record as a reduction to right-of-use (“ROU”) assets 
and the related operating lease liabilities. Our lease agreements generally contain lease and non-lease components, and 
we combine fixed payments for non-lease components with lease payments and account for them together as a single 
lease component. Certain lease agreements may contain variable payments, which are expensed as incurred and not 
included in the right-of-use lease assets and operating lease liabilities. When renewal options are reasonably certain of 
exercise, we include the renewal period in the lease term. In many cases, we have leases with a term of less than one 
year. We elected the practical expedient to exclude these short-term leases from our ROU assets and operating lease 
liabilities. On an ongoing basis, we negotiate and execute new leases to meet business objectives. 
Right-of-use assets and operating lease liabilities are recognized at the present value of the future lease 
payments on the lease commencement date. The interest rate used to determine the present value of the future lease 
payments is our incremental borrowing rate because the interest rate implicit in our leases is not readily determinable. 
Our incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms 
and payments. We have a centrally managed treasury function; therefore, we apply a portfolio approach for determining 
the incremental borrowing rate applicable to the lease term. Operating lease expense is recognized on a straight-line 
basis over the lease term. 
We evaluate the useful life and test for impairment whenever events or changes in circumstances indicate the 
carrying amount of an asset group containing the right-of-use assets may not be recoverable. 
Intangible Assets and Goodwill 
Our intangible assets consist of customer relationships, developed technology, trademarks, patents, and 
intellectual property, which are stated at cost less accumulated amortization. Intangible assets, which are considered 
long-lived assets, are amortized over their estimated useful lives and reviewed for impairment when events or changes in 
circumstances indicate that the carrying amount of an asset group containing these assets may not be recoverable. 
Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired in 
a business combination. We evaluate goodwill for impairment as a single reporting unit annually during the fourth 
quarter or when events or changes in circumstances indicate the carrying value may not be recoverable.  
Our goodwill impairment evaluation consists of a qualitative assessment. If this assessment indicates it is more 
likely than not that the Company’s estimated fair value exceeds the carrying value of our net assets, we do not consider 
goodwill to be impaired. Otherwise, we perform a quantitative assessment by comparing the Company’s fair value to the 
carrying value of our net assets, including goodwill. If the carrying value of our net assets exceeds the fair value, we 
consider goodwill to be impaired.  
Based on the facts and circumstances, we determine the fair value based on an income, market, or cost 
approach. Each method is subjective in nature and involves the use of significant estimates and assumptions, which can 
include projected financial results, discount rates, long-term growth rates, and industry trends. 
Debt Issuance Costs 
We capitalize costs associated with issuing debt. Depending on the nature of the agreement, we record these 
costs on the Consolidated Balance Sheets either in other assets or as a direct deduction from the carrying amount of the 
debt. We amortize the costs over the term of the agreement using the effective interest method. Amortization expense is 
reflected within interest expense on the Consolidated Statements of Operations. See Note 18. Long-Term Debt for 
additional details.

Revenue Recognition 
Net revenue consists of products and support services. 
We recognize substantially all revenue at a point in time when we satisfy our performance obligations. 
Typically, this occurs on shipment of goods because, at that point, we transfer control to our customer. The transaction 
price is based upon the standalone selling price. In most transactions, we have no obligations to our customers after the 
date products are shipped, other than pursuant to warranty obligations. We recognize revenue net of any taxes collected 
from customers, which are subsequently remitted to governmental authorities. Surcharges, cost recoveries, and shipping 
and handling fees billed to customers, if any, are recognized as revenue. The related cost for shipping and handling fees 
is recognized in cost of revenue.  
Support services include warranty and non-warranty repair services, upgrades, and refurbishments on the 
products we sell. Repairs covered under our standard warranty do not generate revenue. We recognize substantially all 
non-warranty revenue upon completion of the service because that is the point in time when we satisfy our performance 
obligation. 
As part of our ongoing service business, we satisfy our service obligations under preventative maintenance 
contracts and extended warranties. Up-front fees received for extended warranties or maintenance plans are deferred and 
recorded in customer deposits and other on the Consolidated Balance Sheets. Revenue under these arrangements is 
recognized ratably over the underlying terms, as we do not have historical information that would allow us to project the 
estimated service usage pattern at this time.  
We expense the incremental costs of obtaining contracts when the amortization period of the costs is less than 
one year. These costs are included in selling, general, and administrative expenses in our Consolidated Statements of 
Operations.  
Our remaining performance obligations primarily relate to customer purchase orders for products we have not 
yet shipped. We expect to fulfill the majority of these performance obligations within one year. 
Research and Development Expenses 
Costs incurred to advance, test, or otherwise modify our technology or develop new technologies are considered 
research and development costs and are expensed when incurred. These costs are primarily comprised of costs associated 
with the operation of our laboratories and research facilities, including internal labor, materials, and overhead. 
Stock-Based Compensation 
Accounting for stock-based compensation requires the measurement and recognition of compensation expense 
for all stock-based awards made to employees and directors based on estimated fair value at the grant date.  
We estimate the fair value of restricted stock units (“RSUs”) on the grant date. For RSUs that contain a time-
based and/or performance-based vesting condition, we estimate fair value using the closing share price on the grant date.  
We record stock-based compensation expense for awards with time-based vesting conditions on a straight-line 
basis over the requisite service period. For awards with a performance-based vesting condition, we record stock-based 
compensation expense (based on our assessment of the probability of meeting the performance conditions) over the 
estimated period to achieve the performance conditions. If the awards are forfeited, we reverse the stock-based 
compensation expense. 

ADVANCED ENERGY INDUSTRIES, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) 
59 
Certain RSUs vest based on a market condition. Our stock-based compensation expense is based on an estimate 
of the fair value and probability of achievement for each tranche of these awards using a Monte Carlo simulation. For 
these RSUs, we recognize stock-based compensation expense over each tranche’s estimated achievement period even if 
some or all of the shares never vest. 
For all stock awards, we estimate forfeitures at the grant date and revise those estimates in subsequent periods if 
actual forfeitures differ from our estimates.  
Income Taxes 
We follow the liability method of accounting for income taxes under which deferred tax assets and liabilities 
are recognized for future tax consequences. A deferred tax asset or liability is computed for both the expected future 
impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future 
tax benefit to be derived from tax loss and tax credit carryforwards. Tax rate changes are reflected in the period such 
changes are enacted. 
We assess the recoverability of our net deferred tax assets and the need for a valuation allowance on a quarterly 
basis. Our assessment includes several factors, including historical results and taxable income projections for each 
jurisdiction. The ultimate realization of deferred income tax assets is dependent on the generation of taxable income in 
appropriate jurisdictions during the periods in which those temporary differences are deductible. We consider the 
scheduled reversal of deferred income tax liabilities, projected future taxable income, and tax planning strategies in 
determining the amount of the valuation allowance. Based on the level of historical taxable income and projections for 
future taxable income over the periods in which the deferred income tax assets are deductible, we determine if we will 
more likely than not realize the benefits of these deductible differences. 
Accounting for income taxes requires a two-step approach to recognize and measure uncertain tax positions. 
The first step is to evaluate the tax position for recognition by determining, if based on the technical merits, it is more 
likely than not that the position will be sustained upon audit, including resolutions of related appeals or litigation 
processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of 
being realized upon ultimate settlement. We regularly assess the likelihood of favorable or unfavorable outcomes 
resulting from these examinations to determine the adequacy of our provision for income taxes. This evaluation is based 
on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues 
under audit, and new audit activity. 
Under U.S. GAAP, an accounting policy election can be made to either recognize deferred taxes for temporary 
basis differences expected to reverse as global intangible low-tax income (“GILTI”) in future years, or to provide for the 
tax expense related to GILTI in the year that the tax is incurred as a period expense only. We have elected to account for 
GILTI in the year that the tax is incurred. 
Commitments and Contingencies 
We are involved in disputes and legal actions arising in the normal course of our business. While we currently 
believe that the amount of any ultimate loss would not be material to our financial position, the outcome of these actions 
is inherently difficult to predict. In the event of an adverse outcome, the ultimate loss could have a material adverse 
effect on our financial position or reported results of operations. An unfavorable decision in intellectual property 
litigation also could require material changes in production processes and products or result in our inability to ship 
products or components found to have violated third party intellectual property rights. We accrue loss contingencies in 
connection with our commitments and contingencies, including litigation, when it is probable that a loss has occurred, 
and the amount of such loss can be reasonably estimated. We are not currently a party to any legal action that we believe 
would reasonably have a material adverse impact on our business, financial condition, results of operations or cash 
flows.

New Accounting Standards 
From time to time, the Financial Accounting Standards Board (“FASB”) or other standards setting bodies issue 
new accounting pronouncements. Updates to the FASB Accounting Standards Codification (“ASC”) are communicated 
through issuance of an Accounting Standards Update (“ASU”). Unless otherwise discussed, we believe that the impact 
of recently issued guidance, whether adopted or to be adopted in the future, will not have a material impact on the 
consolidated financial statements upon adoption. 
New Accounting Standards Adopted 
In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280) Improvements to 
Reportable Segment Disclosures.” The amendments in ASU 2023-07 expand disclosure requirements. In addition, the 
ASU enhances interim disclosures, clarifies circumstances in which an entity can disclose multiple segment measures of 
profit or loss, and provides new disclosures requirements for entities with a single reportable segment. We adopted this 
guidance on December 31, 2024, and it was not material to our consolidated financial statements. 
New Accounting Standards Issued But Not Yet Adopted  
In December 2023, the FASB issued ASU 2023-09 “Improvements to Income Tax Disclosures.” ASU 2023-09 
requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional 
disclosure on income taxes paid. This guidance will be effective for us on January 1, 2025 for annual disclosures. We do 
not expect the above guidance to materially impact our consolidated financial statements. 
In March 2024, the SEC issued climate-related disclosure rules. These rules do not change accounting 
treatment, but they significantly expand the climate-related information companies are required to disclose. Several 
petitions were filed challenging these climate-related disclosure rules and, in April 2024, the SEC voluntarily stayed the 
rules, pending completion of judicial review. Disclosure requirements, absent the results of pending legal challenges, 
may begin phasing in with our annual reporting for the year ending December 31, 2025. We do not expect the above 
disclosure requirement to materially impact our consolidated financial statements. We are evaluating the disclosure 
requirements and changes to our business processes, systems, and controls to support the additional disclosures.  
In November 2024, the FASB issued ASU 2024-03 final standard on Income Statement: Disaggregation of 
Income Statement Expenses, which requires disaggregated disclosure of income statement expenses for public business 
entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it 
requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the 
financial statements. This guidance will be effective for us on January 1, 2027. We do not expect the above guidance to 
materially impact our consolidated financial statements.

Deferred tax assets and liabilities are recognized for the future tax consequences of differences between the 
carrying amounts of assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in 
which the differences are expected to be reversed. Significant deferred tax assets and liabilities consist of the following:

Of the $120.8 million and $100.5 million net deferred tax assets as of December 31, 2024 and 2023, 
respectively, $121.4 million and $107.9 million, respectively, were included as a net non-current deferred tax asset 
within other assets on the Consolidated Balance Sheets. $0.6 million and $7.4 million, respectively, were included as a 
net non-current deferred tax liability within other long-term liabilities on the Consolidated Balance Sheets. 
During the fourth quarter of 2024, we completed the transfer of certain intellectual property between certain of 
our legal entities in connection with simplifying our corporate legal entity structure. The tax impact of the transfer 
resulted in the recognition of deferred tax assets totaling approximately $23.0 million with a corresponding decrease to 
tax expense.  
As of December 31, 2024, we have recorded a total valuation allowance on $2.9 million of our U.S. domestic 
deferred tax assets, largely attributable to state carryforward attributes that are expected to expire before sufficient 
income can be realized in those jurisdictions. The remaining valuation allowance on deferred tax assets approximates 
$39.4 million and is associated primarily with operations in Hong Kong, Germany, China, and Switzerland. As of 
December 31, 2024, there is not sufficient positive evidence to conclude that such deferred tax assets, presently reduced 
by a valuation allowance, will more likely than not be recognized. The December 31, 2024 valuation allowance balance 
reflects an increase of $4.4 million during the year. 
As of December 31, 2024, we had U.S., foreign and state tax loss carryforwards of $31.3 million, $277.7 
million, and $107.2 million, respectively. Additionally, we had $1.6 million and $30.5 million of capital loss and interest 
expense limitation carryforwards, respectively. Finally, we had U.S. and state tax credit carryforwards of $0.1 million 
and $2.3 million, respectively. The U.S. and state net operating losses, tax credits, and interest expense limitation are

subject to various utilization limitations under Section 382 of the Internal Revenue Code and applicable state laws. 
These Section 382 limited attributes have various expiration periods through 2036 or, in the case of the interest expense 
limitation amount, no expiration period. Much of the foreign loss carryforwards, and $9.7 million of the federal net 
operating loss carry forwards, have no expiration period. 
We operate under a tax holiday in Singapore, China, and Malaysia. These tax holidays are in effect through 
June 30, 2027, December 31, 2025, and January 31, 2025, respectively. The tax holidays are conditional upon our 
meeting certain employment and investment thresholds. The expected benefit of these tax holidays may be limited by the 
impact of Pillar II global minimum tax or other actions taken by these countries. For the years ended December 31, 
2024, 2023 and 2022, the impact of the tax holidays decreased foreign taxes by $12.4 million, $14.3 million, and $19.4 
million, respectively, and the benefit on earnings per diluted share was $0.33, $0.38, and $0.52, respectively. 
As of December 31, 2024, we have undistributed earnings in certain foreign subsidiaries of approximately 
$36.3 million that we have indefinitely invested, and on which we have not recognized deferred taxes. Estimating the 
amount of potential tax is not practicable because of the complexity and variety of assumptions necessary to compute the 
tax. 
We account for uncertain tax positions by applying a minimum recognition threshold to tax positions before 
recognizing these positions in the consolidated financial statements. The following table provides a reconciliation of our 
total gross unrecognized tax benefits, which we include within other long-term liabilities on the Consolidated Balance 
Sheets:

The unrecognized tax benefits of $5.7 million, if recognized, will impact our effective tax rate. In accordance 
with our accounting policy, we recognize accrued interest and penalties related to unrecognized tax benefits as a 
component of tax expense. We had $0.8 million and $0.7 million of accrued interest and penalties on December 31, 2024 
and 2023, respectively. With few exceptions, we are no longer subject to federal, state, or foreign income tax 
examinations by tax authorities for years before 2020. 
 
As of January 1, 2024, the Pillar II minimum global effective tax rate of 15% enacted by the Organization for 
Economic Cooperation and Development (“OECD”) was effectuated. More than 140 countries agreed to enact the 
Pillar II global minimum tax. However, the timing of the implementation for each country varies. For the year ended 
December 31, 2024, we included an estimate of global minimum tax liability as a result of those countries where we 
conduct business that have adopted Pillar II. As countries continue to make revisions to their legislation and release 
additional guidance with respect to the global minimum tax, we continue to determine any potential impact in the 
countries in which we operate. The impact of these changes may have a material impact on our cash tax expense and tax 
rate.

We compute basic earnings per share of common stock (“Basic EPS”) by dividing income available to common 
stockholders by the weighted-average number of common shares outstanding during the period.  
See Note 18. Long-Term Debt for information regarding our Convertible Notes, Note Hedges, and Warrants. 
For diluted earnings per share of common stock (“Diluted EPS”), we increase the weighted-average number of common 
shares outstanding during the period, as needed, to include the following: 
• 
Additional common shares that would have been outstanding if our outstanding stock awards had been 
converted to common shares using the treasury stock method. We exclude any stock awards that have 
an anti-dilutive effect; 
• 
Dilutive impact associated with the Convertible Notes using the if-converted method. The Convertible 
Notes are repayable in cash up to par value and in cash or shares of common stock for the excess over 
par value. When the stock price is lower than the strike price, there is no dilutive or anti-dilutive 
impact. Prior to conversion, we do not consider the Note Hedges for purposes of Diluted EPS as their 
effect would be anti-dilutive. Upon conversion, we expect the Note Hedges to offset the dilutive effect 
of the Convertible Notes when the stock price is above $137.46 but below $179.76; and 
• 
Dilutive effect of the Warrants issued concurrently with the Convertible Notes using the treasury stock 
method. For all periods presented, the Warrants did not increase the weighted-average number of 
common shares outstanding because the $179.76 exercise price of the Warrants exceeded the average 
market price of our common stock.

NOTE 7.           DERIVATIVE FINANCIAL INSTRUMENTS 
Changes in foreign currency exchange rates impact our results of operations and cash flows. We may manage 
these risks through the use of derivative financial instruments, primarily forward contracts with banks. These forward 
contracts manage the exchange rate risk associated with assets and liabilities denominated in nonfunctional currencies. 
Typically, we execute these derivative instruments for one-month periods and do not designate them as hedges for 
accounting purposes; however, they do partially offset the economic fluctuations of certain of our assets and liabilities 
due to foreign exchange rate changes. The gains and losses related to these foreign currency exchange contracts are 
intended to offset the corresponding gains and losses on the revaluation of the underlying assets and liabilities. Both are 
included as a component of other income (expense), net in our Consolidated Statements of Operations. 
At December 31, 2024 we have $70.6 million foreign currency forward contracts outstanding. There were no 
foreign currency forward contracts outstanding at December 31, 2023. 
We had interest rate swap contracts that fixed a portion of the interest payments on our Term Loan Facility. The 
interest rate swap contracts expired on September 10, 2024. In connection with the expiration, there are no longer any 
related balances for these contracts within accumulated other comprehensive income (loss) on the Consolidated Balance 
Sheets as of December 31, 2024. See Note 18. Long-Term Debt in Part II, Item 8 “Financial Statements and 
Supplementary Data.” 
See Note 6. Fair Value Measurements for information regarding the fair value of derivative instruments. 
As a result of using derivative financial instruments, we are exposed to the risk that counterparties to contracts 
could fail to meet their contractual obligations. We manage this credit risk by reviewing counterparty creditworthiness 
on a regular basis and limiting exposure to any single counterparty. 
NOTE 8.           ACCOUNTS RECEIVABLE, NET 
We record accounts receivable at net realizable value. Our accounts receivable, net balance on the Consolidated 
Balance Sheets was $265.3 million at December 31, 2024. The following table summarizes the changes in expected

Restructuring 
We have several restructuring plans in process: 
2024 Plan 
On July 29, 2024, we approved actions in furtherance of our manufacturing consolidation initiatives intended to 
optimize our manufacturing footprint and cost structure, including the closure of our Zhongshan, China manufacturing 
facility (the “2024 Plan”). In connection with the 2024 Plan, we recorded a $29.6 million charge primarily associated 
with expected employment-related charges for, among other things, one-time cash payments for severance, benefits 
expenses, payroll taxes, and other ancillary costs. The charge includes estimated liabilities for lease termination and 
facility exit costs, which could be subject to further adjustments. The remaining contractual rental obligations under the 
lease agreements are recorded in current portion of operating lease liabilities and operating lease liabilities on our 
Consolidated Balance Sheets. 
 
The amounts incurred as a result of the approved actions are estimates and actual results may differ, which 
could result in incremental restructuring charges in future periods. We anticipate the 2024 Plan will be substantially 
completed by the end of second quarter of 2025, with final activities expected to conclude in 2026. 
 
2023 Plan 
In 2023, we approved a plan intended to optimize and further consolidate our manufacturing operations and 
functional support groups as well as a general reduction-in-force to align our expenses to revenue levels (the “2023 
Plan”). We expect to incur approximately $1.0 million in additional charges through the second quarter of 2025. The 
2023 Plan is substantially complete, with the final activities expected to conclude in 2026.  
 
2022 Plan 
This plan was approved to improve our operating efficiencies and drive the realization of synergies from our 
business combinations by consolidating our operations, optimizing our factory footprint, including moving certain 
production into our higher volume factories, reducing redundancies, and lowering our cost structure. The 2022 Plan is 
now complete.

NOTE 15.           EMPLOYEE RETIREMENT PLANS AND POSTRETIREMENT BENEFITS 
Defined Contribution Plans 
We have a 401(k) profit-sharing and retirement savings plan covering substantially all full-time 
U.S. employees. Participants may defer up to the maximum amount permitted by law. Participants are immediately 
vested in both their own contributions and profit-sharing contributions. Profit-sharing contributions, which are 
discretionary, are approved by the Board. For all periods presented, we based our profit-sharing contribution on 
matching 100% of employee contributions up to 3% of compensation plus an additional match of 50% on the next 2% of 
compensation. 
During the years ended December 31, 2024, 2023, and 2022 we recognized total defined contribution plan costs 
of $5.0 million, $5.1 million, and $4.5 million, respectively. 
Defined Benefit Plans 
We maintain defined benefit pension plans for certain of our non-U.S. employees in the United Kingdom, 
Germany, and Philippines. Each plan is managed locally and in accordance with respective local laws and regulations.  
To measure the expense and related benefit obligation, we make various assumptions, including discount rates 
used to value the obligation, expected return on plan assets used to fund these expenses, and estimated future inflation 
rates. We base these assumptions on historical experience as well as current facts and circumstances. We use an actuarial 
analysis to measure the expense and liability associated with pension benefits. 
The information provided below includes one pension plan which is part of discontinued operations. As such, 
for all periods presented, all related expenses are reported in discontinued operations in the Consolidated Statements of 
Operations.

(the “2023 Incentive Plan”) and the Employee Stock Purchase Plan (“ESPP”). We issue all new equity compensation 
grants under the 2023 Incentive Plan. Outstanding awards previously issued under inactive plans will continue to vest 
and remain exercisable in accordance with the terms of the respective plans. 
The 2023 Incentive Plan provides for the grant of awards including stock options, stock appreciation rights, 
performance stock units, performance units, stock, restricted stock, restricted stock units, and cash incentive awards.  
The following table summarizes information related to our stock-based incentive compensation plans:

Stock-based Compensation Expense 
We recognize stock-based compensation expense based on the fair value of the awards issued and the functional 
area of the employee receiving the award. For the year ended December 31, 2024, stock-based compensation expense 
includes $1.8 million related to a modification for accounting purposes of prior awards and $1.9 million related to the 
Airity acquisition (see Note 2. Acquisition). Stock-based compensation expense was as follows:

Restricted Stock Units 
Generally, we grant restricted stock units (“RSUs”) with a three year time-based vesting schedule. Certain 
RSUs contain performance-based or market-based vesting conditions in addition to the time-based vesting requirements. 
RSUs are generally granted with a grant date fair value based on the market price of our stock on the date of grant.

The weighted-average grant date fair value for RSUs granted in the years ended December 31, 2024, 2023, and 
2022 was $104.84, $100.04, and $74.62, respectively. The fair value of RSUs vested for the years ended December 31, 
2024, 2023 and 2022 was $28.2 million, $19.5 million, and $13.5 million, respectively. As of December 31, 2024, there 
was $53.4 million of total unrecognized compensation cost, net of expected forfeitures, related to non-vested RSUs, that 
we expect to recognize through December 2027, with a weighted-average remaining vesting period of 1.0 years. 
Stock Options 
Generally, we grant stock option awards with an exercise price equal to the market price of our stock at the date 
of grant and with either a three or four-year vesting schedule or performance-based vesting. Stock option awards 
generally have a term of ten years. 
Changes in our stock options were as follows:

outstanding and exercisable was $2.6 million and $1.8 million, respectively. As of December 31, 2024, there was $0.2 
million of total unrecognized compensation cost, net of expected forfeitures, related to the unvested options that we 
expect to recognize over a remaining period of 0.2 years.  
Employee Stock Purchase Plan 
The ESPP is a stockholder-approved plan that allows eligible employees to purchase our common stock at a 
discount. Employees who meet the eligibility criteria may contribute up to the lesser of 15% of their eligible earnings or 
$5,000 during each plan period. Currently, the plan period is six months. The purchase price of common stock purchased 
under the ESPP is currently equal to the lower of 1) 85% of the fair market value of our common stock on the 
commencement date of each plan period or 2) 85% of the fair market value of our common shares on each plan period 
purchase date.  
As of December 31, 2024, there was $0.5 million of total unrecognized compensation cost related to the ESPP 
that we expect to recognize over a remaining period of five months.

Deferred Compensation Plan  
We offer certain employees the opportunity to elect to defer compensation for salary, bonus, commission, and 
stock awards. The Company maintains a rabbi trust in connection with the deferred compensation plan. Assets of the 
rabbi trust not held in Company shares are presented in other assets, and the fair value of the Company shares held in the 
rabbi trust is classified in stockholders’ equity. After a holding period, employees have the option to diversify the 
Company shares into other funds. Stock awards that have been elected for deferral but have not yet vested and are 
probable of vesting are reported as deferred compensation in the temporary equity section of the Consolidated Balance 
Sheets. The stock awards recorded in temporary equity are recognized at fair value, with any difference from stock-
based compensation recorded in retained earnings.  
 
 
NOTE 17.           COMMITMENTS AND CONTINGENCIES 
We are involved in disputes and legal actions arising in the normal course of our business. While we currently 
believe that the amount of any ultimate loss would not be material to our financial position, the outcome of these actions 
is inherently difficult to predict. In the event of an adverse outcome, the ultimate loss could have a material adverse 
effect on our financial position or reported results of operations. An unfavorable decision in intellectual property 
litigation also could require material changes in production processes and products or result in our inability to ship 
products or components found to have violated third party intellectual property rights. We accrue loss contingencies in 
connection with our commitments and contingencies, including litigation, when it is probable that a loss has occurred, 
and the amount of such loss can be reasonably estimated. We are not currently a party to any legal action that we believe 
would have a material adverse impact on our business, financial condition, results of operations or cash flows.  
We maintain defined benefit pension plans for certain of our non-U.S. employees, including those in the United 
Kingdom. In light of the United Kingdom’s High Court ruling in the case of Virgin Media Ltd v. NTL Pension 
Trustees II Ltd & Ors, we reviewed past amendments made to our United Kingdom pension plans. While unlikely, 
should there be a challenge to any previous amendments, we could face potential litigation and compliance risks. We 
continue to account for our United Kingdom pension plans in accordance with the plan agreements and amendments, as 
we believe they represent a mutual understanding and agreement among all parties.

Credit Agreement 
Our credit agreement dated as of September 10, 2019, as amended (the “Credit Agreement”) consists of a senior 
unsecured term loan facility (“Term Loan Facility”) and a senior unsecured revolving facility (“Revolving Facility”), 
both maturing on September 9, 2026.  
On September 9, 2024, we entered into an amendment to the Credit Agreement to increase the capacity on the 
Revolving Facility from $200.0 million to $600.0 million. This amendment was in connection with the concurrent 
prepayment, using existing cash on hand, of the full $345.0 million outstanding principal balance under our Term Loan 
Facility. 
For all periods presented, no amounts were outstanding on the Revolving Facility. The following table 
summarizes our availability to withdraw on the Revolving Facility:

In addition to our available capacity on the Revolving Facility, prior to the maturity date of the Credit 
Agreement, we may request an increase to the financing commitments in either the Term Loan Facility or Revolving 
Facility by an aggregate amount not to exceed $250.0 million. Any requested increase is subject to lender approval. 
The interest rate swap contracts previously entered into relative to the Term Loan Facility expired on September 
10, 2024. Should we have future borrowings under the Term Loan Facility or Revolving Facility, they will bear interest, 
at our option, at a rate based on the Base Rate or SOFR, as defined in the Credit Agreement, plus an applicable margin. 
 
Convertible Senior Notes due 2028 
On September 12, 2023, we completed a private, unregistered offering of $575.0 million aggregate principal 
amount of 2.50% convertible senior notes due 2028 (“Convertible Notes”). The $564.7 million remaining outstanding 
principal amount of the Convertible Notes, net of unamortized issuance costs, continues to be classified as long-term 
debt as none of the conversion triggers occurred as of December 31, 2024.  
The Convertible Notes mature on September 15, 2028, unless earlier repurchased, redeemed, or converted. 
Interest is payable semi-annually in arrears in March and September. We do not maintain a sinking fund.  

ADVANCED ENERGY INDUSTRIES, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) 
83 
We may redeem for cash all or any portion of the Convertible Notes, at our option, on or after September 20, 
2026 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for 
at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period (including the last 
trading day of such period). The redemption price is 100% of the principal amount plus accrued and unpaid interest. 
Prior to May 15, 2028, holders have the option to convert all or a portion of their Convertible Notes under the 
following circumstances: 
• 
during any calendar quarter if the last reported sale price of our common stock, for at least 20 trading 
days (whether or not consecutive) during a period of 30 consecutive trading days is greater than or 
equal to 130% of the conversion price on each applicable trading day;  
• 
during the five business day period immediately after any five consecutive trading day period in which 
the trading price per $1,000 principal amount of the Convertible Notes for each trading day was less 
than 98% of the product of the last reported sale price of our common stock on each such trading day 
and the conversion rate on each such trading day;  
• 
if Advanced Energy calls any or all of the Convertible Notes for redemption; or  
• 
upon the occurrence of specified corporate transactions or events described in the indenture. 
From May 15, 2028 through the maturity date, holders have the option to convert at any time regardless of 
circumstances. 
The initial conversion rate is 7.2747 shares of common stock per $1,000 principal amount, which is equivalent 
to an initial conversion price of approximately $137.46 per share of common stock. The conversion rate is subject to 
adjustment upon the occurrence of certain specified events as set forth in the indenture.  
Upon conversion, Advanced Energy will do the following: 
• 
pay cash up to the aggregate principal amount to be converted; and  
• 
pay or deliver cash, shares of our common stock, or a combination (at our election) with respect to the 
remainder, if any, of the conversion obligation in excess of the aggregate principal amount being 
converted.  
Concurrent with the Convertible Notes issuance, we entered into hedges (“Note Hedges”) with respect to our 
common stock and sold warrants to purchase our common stock (“Warrants”). In combination, the Note Hedges and 
Warrants synthetically increase the initial conversion price on the Convertible Notes from $137.46 to $179.76, reducing 
the potential dilutive effect. 
The Warrants provide the counterparties the option to acquire approximately 4.2 million aggregate shares of our 
common stock (subject to customary anti-dilution adjustments), which is the same number of shares of our common 
stock covered by the Note Hedges at a $179.76 per share initial exercise price, which represents a 70% premium over the 
$105.74 closing price of our common stock on September 7, 2023. The Warrants expire on July 7, 2029.  
If the market value per share of our common stock exceeds the exercise price of the Warrants during the 
measurement period at the maturity of such Warrants, the Warrants will have a dilutive effect on our earnings per share 
as we will owe the counterparties a number of shares of common stock in an amount based on the excess of such market 
price per share of the common stock over the Warrants’ exercise price.  

ADVANCED ENERGY INDUSTRIES, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) 
84 
The Note Hedge and Warrants are separate from the Convertible Notes. The Convertible Notes holders have no 
rights with respect to the Note Hedges and Warrants. Counterparties in the Note Hedge and Warrants transactions have 
no rights with respect to the Convertible Notes.  
We use level 2 measurements to estimate the fair value of our debt. As of December 31, 2024, we estimate the 
fair value of our Convertible Notes to be $624.6 million.

ITEM 9.            CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND 
FINANCIAL DISCLOSURE 
Not applicable. 
ITEM 9A.          CONTROLS AND PROCEDURES 
Evaluation of Disclosure Controls and Procedures 
We have established disclosure controls and procedures, which are designed to ensure that information required 
to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported, 
within the time periods specified in the SEC’s rules and forms. These disclosure controls and procedures include, 
without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports 
that we file or submit under the Exchange Act is accumulated and communicated to management, including our 
Principal Executive Officer (Stephen D. Kelley, President and Chief Executive Officer) and Principal Financial Officer 
(Paul R. Oldham, Executive Vice President and Chief Financial Officer), as appropriate, to allow timely decisions 
regarding required disclosures. 
As of the end of the period covered by this report, we conducted an evaluation, with the participation of 
management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and 
operation of the disclosure controls and procedures pursuant to the Exchange Act Rule 13a-15(b). Based upon this 
evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and 
procedures were effective as of December 31, 2024. The conclusions of the Chief Executive Officer and Chief Financial 
Officer from this evaluation were communicated to the Audit and Finance Committee. Management recognizes that any 
controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving 
their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible 
controls and procedures. We intend to continue to review and document our disclosure controls and procedures, 
including our internal controls over financial reporting, and may from time to time make changes aimed at enhancing 
their effectiveness and to ensure that our systems evolve with our business. 
Management’s Annual Report on Internal Control over Financial Reporting 
It is management’s responsibility to establish and maintain effective internal control over our financial 
reporting, which is a process designed under the supervision of our Chief Executive Officer and Chief Financial Officer 
and effected by our Board of Directors, management, and other personnel. Our internal control over financial reporting 
is designed to provide reasonable assurance concerning the reliability of our financial reporting and the preparation of 
our financial statements for external purposes in accordance with generally accepted accounting principles.  
Management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the 
effectiveness of our internal control over financial reporting as of December 31, 2024, using the criteria described in 
Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission. Based upon this evaluation, management concluded that our internal control over financial reporting was 
effective as of December 31, 2024. 
Ernst & Young LLP, an independent registered public accounting firm, has audited our consolidated financial 
statements included in this Form 10 - K, and as part of the audit, has issued an audit report, included herein, on the 
effectiveness of our internal control over financial reporting as of December 31, 2024. 
Changes in Internal Control over Financial Reporting 
There was no change in our internal control over financial reporting that occurred during the fourth quarter of 
the current year that has materially affected, or is reasonably likely to materially affect, our internal control over 
financial reporting. 

86 
Limitations on Controls and Procedures 
Management concluded that our disclosure controls and procedures and internal control over financial reporting 
provide reasonable assurance that the objectives of our control system are met. We do not expect, however, that our 
disclosure controls and procedures or internal control over financial reporting will prevent or detect all misstatements, 
errors, or fraud, if any. All control systems, no matter how well designed and implemented, have inherent limitations, 
and therefore no evaluation can provide absolute assurance that every misstatement, error, or instance of fraud, if any, or 
risk thereof, has been or will be prevented or detected. The occurrence of a misstatement, error, or fraud, if any, would 
not necessarily require a conclusion that our controls and procedures are not effective. 
ITEM 9B.          OTHER INFORMATION 
During the fourth quarter of 2024, two of our officers adopted a “Rule 10b5-1 trading arrangement” (as defined 
in Item 408 of Regulation S-K) intended to satisfy the affirmative defense conditions of Rule 10b5-1(c), as amended.
