SEMICONDUCTOR EQUIPMENT MARKET

The Semiconductor Equipment market is driven by the long-term growing need for more semiconductor production capacity and new process technologies. While the semiconductor and semiconductor equipment industries are inherently cyclical, over the long-term, integrated circuits content is growing across many industries driven by increased demand for processing, storing, and transmitting the growing amount of data. To meet the growing demand, the chip industry continues to invest in production capacity for both leading-edge and trailing-edge nodes logic devices, the latest memory devices, back-end test, and advanced wafer-level packaging. The industry’s transition to advanced technology nodes and to increased layers in memory devices require an increased number of plasma-based etch and deposition process tools and higher content of our advanced power solutions per tool. As etching and deposition processes become more challenging due to shrinking device geometry and increasing aspect ratios in advanced 3D devices, more advanced RF and DC plasma generation technologies are needed. We strive to provide a broad range of best-in-class, industry-leading RF and DC power solutions. Beyond etch and deposition processes, growing complexity at advanced nodes also drives a higher number of other process steps across the wafer fab, including inspection, metrology, thermal, ion implantation, and semiconductor test and assembly, where Advanced Energy is actively participating as a critical technology provider. In addition, our global support services group offers comprehensive local repair service, upgrade, and retrofit offerings to extend the useable life of our customers’ capital equipment for additional technology generations. Our strategy in the Semiconductor Equipment market is to defend our proprietary positions in our core applications by capturing new design and product generations, growing our market position in applications where we have lower market share, such as remote plasma source and dielectric etch, and leveraging our product portfolio in areas including embedded power, high voltage power systems, and critical sensing and controls to grow our market share and content at our original OEM customers.

Refer to Note 3. Revenue in Part II, Item 8 “Financial Statements and Supplementary Data” for information regarding our revenue by geographic area and Part I, Item 1A “Risk Factors” for a discussion of certain risks related to our foreign operations.

Manufacturing

The manufacturing of our products is primarily performed at our sites in the Philippines, Malaysia, and China. In addition, we perform limited specialty manufacturing for some of our products in the U.S., Mexico, United Kingdom, and Europe. See Part I, Item 1A, “Risk Factors” for a discussion of certain risks related to our manufacturing operations.

Manufacturing requires raw materials, including a wide variety of mechanical and electrical components, to be manufactured to our specifications. We use numerous companies, including contract manufacturers, to supply parts for the manufacture and support of our products. Although we make reasonable efforts to assure that parts are available from multiple qualified suppliers, some key parts may be obtained from a sole supplier or a limited group of suppliers. Global supply chain constraints have impacted the availability of materials, parts, and subcomponents needed for production. In some cases, we paid premiums or expedite fees to obtain critical parts to meet urgent customer needs. In some of those instances, we passed the additional costs along to our customers. We expect the related supply chain challenges will continue into 2023. However, we seek to reduce costs, lower the risks of production and service interruptions, and mitigate key parts shortages by:

| ● | selecting and qualifying alternate suppliers where practical for key parts using rigorous technical and commercial evaluation of suppliers’ products and business processes including testing their components’ performance, quality, and reliability on our power conversion products used in our customers’ and their customers’ processes. The qualification process for our process power products, particularly as it pertains to semiconductor customers, follows semiconductor industry standard practices, such as “copy exact;”

| ● | monitoring the financial condition and overall performance of key suppliers from stable geographies;

| ● | procuring alternate parts from commercial, widely available nodes and processes;

| ● | maintaining appropriate inventories of key parts, including making last time purchases of key parts when notified by suppliers that they are ending the supply of those parts;

| ● | qualifying new parts where possible and in geographies that reduce costs without degradation in quality; and

| ● | locating certain manufacturing operations in areas that are closer to suppliers and customers.

Intellectual Property

We seek patent protection for inventions governing new products or technologies as part of our ongoing research and development. We currently hold 350 U.S. issued patents and 416 foreign issued patents, and we have 568 patent applications pending in the U.S., Europe, and Asia. A substantial majority of our patents are related to our process power products and solutions business. Generally, our efforts to obtain international patents have been concentrated in the industrialized countries within Europe and Asia because there are other manufacturers and developers of power conversion and control systems in those countries, as well as customers for those systems for which our intellectual property applies. In addition to patents, we possess other intellectual property, including trademarks, know-how, trade secrets, and copyrights. We leverage our proprietary technology and trade secrets to deliver on our strategy of selling differentiated products for our most important customer solutions. During 2022 we strengthened our trade secret and confidential information protection measures including by disabling USB drives on company-issued laptops, increasing the frequency of internal data loss protection searches, and we brought lawsuits against two former employees who misappropriated confidential data.

​

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 cause our results to be adversely impacted and could 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 Securities and Exchange Commission.

Macroeconomic and Industry Risks

The industries in which we compete are subject to volatile and unpredictable fluctuation or cycles.

As a supplier to the global semiconductor equipment, telecom, networking, data center computing, industrial, and medical industries, we are subject to business fluctuations, the timing, length, and volatility of which can be difficult to predict. We are also 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, and access to affordable capital. These changes have affected the timing and amount of customers’ purchases and investments in technology, and continue to affect our orders, net sales, operating expenses, and net income. We may not be able to respond adequately or quickly to the decline in demand by reducing our costs.

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.

We must achieve design wins to retain our existing customers and to obtain new customers, although design wins achieved do not necessarily result in substantial sales.

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

12

Table of Contents

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 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. If existing or new customers do not choose our designs or we agree to suboptimal commercial terms with these customers, our market share may be reduced, the potential revenues related to the lifespan of our customers’ products may not be realized, and our business, financial condition and results of operations could be materially and adversely impacted.

Supply chain disruptions, manufacturing interruptions or delays, or the failure to accurately forecast customer demand, 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 customers’ quarterly forecasts and our annual forecasts. These forecasts are based on our customers’ and our expectations as to demand for our products. As the quarter and the year progress, such demand 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, and we generally have no long-term purchase commitments from our customers, which is typical in the industries we serve. As a result, we are limited in our ability to predict the level of future sales 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, subject to possible cancellation penalties. Delays in delivery schedules and/or customer changes to backlog orders during any particular period could cause a decrease in sales and have a material adverse effect on our business and results of operations. Orders with our suppliers cannot always be amended in response. In addition, to assure availability of certain components or to 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 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. This may lead to customers cancelling orders prior to shipment causing a decrease in sales, which may have a material adverse effect on our business and results of operations.

Beginning in 2021 and continuing into 2023, there has been 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, labor shortages, and other factors. These supply constraints led to longer lead times in procuring materials and subcomponents and, in some cases, meaningfully higher costs for the subcomponents. It is not clear how long global supply constraint conditions will continue, how quickly the supply chain will recover, the extent to which our mitigating actions will be successful, or to what extent we can recover our higher costs. As such, our forward-looking projections of revenues, earnings, and cash flow may be adversely impacted if any of these situations continue for longer than we expect or further deteriorate.

Table of Contents

COVID-19 could continue to affect our business, workforce, supply chain, results of operations, financial condition and/or cash flows.

The COVID-19 pandemic has adversely impacted our ability (a) to manufacture, test, service and ship our products, (b) to get required materials and sub-assemblies to build and service our products and (c) to staff labor and management for manufacturing, research and development, supply chain, service, and administrative operations.

COVID-19 continues to impact the global supply chain causing disruptions such as higher input costs through material premiums, expedite fees, price increases, and higher logistic costs. The pandemic has also resulted in economic volatility in many countries, which could adversely impact future customer purchases of our products. The COVID-19 situation continues to evolve and to the extent that it adversely affects our business, financial condition, operating results, and cash flows, it may also have the effect of heightening many of the other risks described in this “Risk Factors” section. Other impacts may arise that we are not aware of currently.

Our results of operations could be affected by natural or other disasters in the locations in which we or our customers or suppliers operate.

We have manufacturing and other operations in locations subject to natural disasters such as severe weather and geological events including earthquakes or tsunamis that could disrupt operations. In addition, our suppliers and customers are also subject to natural and other disaster risk exposure. A natural disaster, fire, explosion, 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, results of operations, or financial condition.

If our information security measures are breached or fail and a customer’s or our data is improperly obtained or unauthorized access to our information technology systems occurs, we may incur significant legal and financial exposure and liabilities.

As part of our day-to-day business, we store our data and certain data about our customers in our global information technology system. We and our third-party providers have experienced, and expect to continue to experience, cybersecurity or confidential information theft incidents, some of which may be successful. We continue to devote significant resources to network security, data encryption, network redundancy, 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, especially in the face of continuously evolving and increasingly sophisticated cybersecurity threats and privacy and data protection laws. Unauthorized access to our data or inability to access our data (e.g. through ransomware or denial of service), including any regarding our technology or customers, could expose us to a risk of loss of this information, loss of business, litigation, and possible liability. These security measures may be breached by intentional misconduct by computer hackers, employee error, employee malfeasance, or otherwise. 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, including our intellectual property and other confidential business information, or our information technology systems. 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. Any security breach or theft of any kind of confidential information including trade secrets could result in a loss of confidence by our customers, damage our reputation, disrupt our business, lead to legal liability, and adversely impact our future sales.

Business Risks

We continue to evolve our manufacturing footprint and where our product lines are manufactured.

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. Natural disasters, uncontrollable occurrences, or other operational issues at any of our manufacturing facilities could significantly reduce or disrupt our productivity at such site and could prevent us from meeting our customers’ requirements in a timely manner, or at all. Additionally, we continue to evaluate our manufacturing facilities and may decide to conduct optimization and consolidation initiatives, which may or may not be successful.

If we are unable to 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 business strategy for many of our product lines has been focused on product performance and technology innovation to provide enhanced efficiencies and productivity. Our customers continually exert pressure on us to reduce our prices and extend payment terms and we may be required to enter into long term reduced pricing agreements, extended payment terms, exclusivity arrangements, or other unfavorable contract terms with our largest customers to remain competitive. In addition, we compete in markets in which customers may dual or multi-source their power. 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. Further, in 2022, we increased prices and implemented surcharges across many of our products to reflect our higher supply chain costs. Although these price changes have generally been accepted by our customers, the higher prices 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 sales and accounts receivable are concentrated among a few customers.

Consistent with prior years, in 2022, two customers each represented over 10% of our total revenue, and our ten largest customers, in the aggregate, accounted for over half of our total revenue. At December 31 2022, one customer accounted for over 10% of our total accounts receivable.

A significant decline in sales from these or our other large customers, or our inability to collect on these sales, could materially and adversely impact our business, results of operations and financial condition.

​

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 macro-economic conditions and a highly competitive labor market. We must develop succession plans capable of maintaining continuity during the inevitable unpredictability of

15

Table of Contents

employee retention. If our succession plans do not operate effectively, our business could be adversely affected. In addition, the loss or retirement of key employees presents particular challenges to the extent it involves the departure of employees with 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 could result in unexpected costs, reduced productivity, or difficulties with respect to internal processes and controls.

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 facility 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 Facility, see Note 21. Credit Facility and Note 8. 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 sales 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.

Our long-term success and results of operations depend on our ability to successfully 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 complete proposed transactions timely or at all due to the failure to obtain regulatory or other approvals, litigation or other disputes, and any ensuing obligation to pay a termination fee;

| ● | 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 all anticipated benefits from business combinations;

| ● | a failure to perform adequate due diligence with respect to business combination and investment transactions and our ability to evaluate the results, is dependent upon the completeness and accuracy of statements and disclosures made or actions taken by third parties and their representatives;

| ● | 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 investment transactions and, to the extent that the value of goodwill or intangible assets acquired in connection with a business combination

|  | and investment transaction becomes impaired, we may be required to 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;

| ● | an inability to integrate with our existing enterprise resource planning (“ERP”) and other global information technology systems to realize productivity improvement and cost efficiencies;

| ● | our ability to diligence and maintain appropriate business processes, procedures, and internal controls at the acquired business;

| ● | the risk of litigation or claims associated with a proposed or completed transaction; and

| ● | unknown, underestimated, undisclosed or undetected commitments or liabilities or non-compliance with laws, regulations, or policies.

During the year ended December 31, 2022, we acquired SL Power, and we are continuing to integrate SL Power with our business. Integrating SL Power’s operations with ours requires significant management attention, effort, and expenditures, and we may not be able to achieve the longer-term integration or other business goals in an effective, complete, timely or cost-efficient manner.

Commercial and Financial Related Risks

We are subject to risks inherent in international operations.

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.

Sales to customers outside the United States represented 61% of our total revenue during the year ended December 31, 2022. Refer to Note 3. Revenue in Part II, Item 8 “Financial Statements and Supplementary Data” for additional information regarding our revenue by geographic area

We are a global organization with an expanding presence in international locations.

Our success producing goods internationally and competing in international markets is subject to our ability to manage various 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;

| ● | 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 protection of intellectual property rights in certain countries;

| ● | 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 new and changing export regulations for certain exports to China and any retaliatory measures;

​

Our debt obligations and the restrictive covenants in 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 debt obligations impose 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 debt obligations, which could result in our credit facility being immediately due and payable, and such default may also constitute a default of our other obligations. 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.

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, or fiscal or monetary concerns, could materially adversely impact our operating results. Tightening of credit markets, turmoil in the financial markets, and a weakening global economy have 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 depend largely on consumer spending. Economic uncertainty exacerbates negative trends in consumer and business spending and may cause our customers to push out, cancel, or refrain from placing orders.

Difficulties or increased costs in obtaining capital and uncertain market conditions may also lead to a reduction of sales and greater instances of nonpayment. These 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 including inflation, interest rates, the transition away from the London Interbank Offered Rate and transition to the Secured Overnight Financing Rate, availability of capital markets, consumer spending rates, energy availability and costs and the effects of government initiatives to manage economic conditions could 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.

​

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 original product warranties ranging from one to ten years with an option to purchase additional warranty coverage for up 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 are experiencing 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 the line “Income (loss) from discontinued operations, net of income taxes” on our Consolidated Statement 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 can be performed profitably, and they 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.

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, particularly when we incorporate new technology into our products or release new versions. Further, the manufacture of these products often involves a highly complex and precise process and the utilization of specially qualified components that conform to stringent specifications. Many of our products also require 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 by us or our suppliers could adversely affect our manufacturing yields and product reliability. If any of our products are defective or fail, we might be required to repair, redesign, or recall those products, pay damages (including liquidated damages) or warranty claims, and we could suffer significant 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,

Table of Contents

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.

Unfavorable currency exchange rate fluctuations may lead to lower operating margins, or may cause us to raise prices, which could result in reduced sales.

Currency exchange rate fluctuations could have an adverse effect on our sales and results of operations, and we could experience losses with respect to forward exchange contracts into which we may enter. Unfavorable currency fluctuations could require us to increase prices to foreign customers, which could result in lower net sales by us to 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 the value of the Philippine Peso, Chinese Yuan, British Pound, Euro, Hong Kong Dollar, and New Taiwan Dollar. 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.

The Chinese government is continually pressured by its trading partners to allow its currency to float in a manner like other major currencies. Any change in the value of the Chinese Yuan could significantly increase the labor and other costs incurred in the operation of our China 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.

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 laws and regulations, possible retaliatory government actions, potential inability to enforce intellectual property protection or contracts terms, and recent 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. We continuously evaluate the risk of operations in China, including manufacturing and supply chain, and the potential financial impact to our operations

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 17. Employee Retirement Plans and Postretirement Benefits in Part II, Item 8 “Financial Statements and Supplementary Data” contained herein.

Our intangible assets may become impaired.

We periodically review the carrying value of our goodwill and the estimated useful lives of our intangible assets, taking into consideration any events or circumstances that might result in either a diminished fair value, or 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

20

material and adverse effect on our financial position and results of operations and could harm the trading price of our common stock.

Regulatory, Legal, Tax, and Compliance Related Risks

Significant developments stemming from recent U.S. government actions with respect to trade policies and export regulations, including export license requirements, tariffs, and trade sanctions have adversely impacted and could further adversely impact our business.

U.S. government actions are imposing greater restrictions and economic disincentives on international trade. Recently, the government has amended and expanded export regulations regarding sales to companies on the U.S. Entity List preventing sales of U.S. foreign direct product, and in October 2022, placed unilateral export controls on the export, reexport, and transfer of technology sold in China for certain advanced computing and semiconductor manufacturing equipment and related parts and services. The implementation and interpretation of these rules is ongoing and evolving and creates challenges in managing our operations and international sales and increases our exposure to foreign competitors. The U.S. government may promulgate additional export controls or license requirements that will further limit our ability to sell products and services to non-U.S. customers, including China. Additionally, the U.S. Department of Defense continues to issue lists of companies it has determined to be owned or controlled by China’s People’s Liberation Army on which sanctions could be levied by executive order, and the Department of Commerce continues to expand the list of designated military end users from China and Russia for whom export licenses are now required. In addition, the US Government has previously initiated the imposition of additional tariffs on certain foreign goods, including steel and aluminum, semiconductor manufacturing equipment and spare parts thereof and has also announced the imposition of import license requirements on aluminum articles.

China has passed numerous regulations, including the Export Control Law of the People’s Republic of China, effective December 1, 2020, the Rules on Counteracting Unjustified Extra-territorial Application of Foreign Legislation and Other Measures promulgated on January 9, 2021, and the Anti-Foreign Sanctions Law of the People’s Republic of China, released on July 24, 2021. These laws provide China with the framework to ban exports to specific foreign entities on its Control List, block application of foreign laws, impose its own sanctions on entities and countries and provides a counterweight to the U.S. government’s restrictions through provisions for retaliatory action and extraterritorial jurisdiction. The potential imposition of retaliatory measures could adversely impact demand for our products, prohibit our ability to sell products or purchase necessary components, and could adversely affect our business.

Changes in U.S. trade policy could result in one or more U.S. trading partners adopting responsive trade policy making it more difficult or costly for us to export our products to those countries. As indicated above, these measures could also result in increased costs for goods imported into the U.S. This in turn could require us to increase prices to our customers which may reduce demand, or, if we are unable to increase prices, result in lowering our margin on goods and services sold. To the extent that trade tariffs and other restrictions imposed by the U.S. increase the price of semiconductor equipment and related parts imported into the U.S., the cost of our materials may be adversely affected and the demand from customers for products and services may be diminished, which could adversely affect our revenues and profitability.

The adoption and expansion of trade restrictions, the occurrence of a trade war, or other governmental action related to tariffs, trade sanctions, or policies has the potential to further adversely impact demand for our products, our costs, our customers, our suppliers, and the U.S. economy, which in turn could adversely impact our business, financial condition, and results of operations.

Changes in U.S. social, political, regulatory, and economic conditions or in laws and policies governing foreign trade, manufacturing, development and investment in the territories and countries where we currently develop and sell products, and any negative sentiments towards the United States as a result of such changes, could adversely affect our business. In addition, negative sentiments towards the United States among non-U.S. customers and among non-U.S. employees or prospective employees could adversely affect sales or hiring and retention, respectively.

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 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 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.

Patent, trademark laws, and trade secret protection may not be adequate to deter infringement or misappropriation of our patents, trademarks, trade secrets and similar proprietary rights. In addition, 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 certain industrialized countries in Asia, 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.

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 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

22

Table of Contents

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 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 to raise more revenues, 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. The U.S., many countries in the European Union, and several other countries are actively considering changes in this regard.

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 related to 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 comprised of 36 countries, including the United States, has made changes to numerous long-standing tax principles. There can be no assurance that these changes, once adopted by countries, 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, including measures to ensure that encryption of users’ data does not hinder law enforcement agencies’ access to that data. 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 recent 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 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; 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 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 in order 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.

Governments, customers, investors, and employees are enhancing their focus on ESG practices and disclosures, and expectations in this area are rapidly evolving and increasing. 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. 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.

Overview

Advanced Energy provides highly engineered, mission-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.

Our plasma power solutions enable innovation in complex semiconductor and thin film plasma processes such as dry etch and deposition. Our broad portfolio of high and low voltage power products are used in a wide range of applications, such as semiconductor equipment, industrial production, medical and life science equipment, data centers computing, networking, and telecommunications. We also supply related sensing, controls, and instrumentation products primarily for advanced measurement and calibration of power and temperature for multiple industrial markets. Our network of global service support centers provides repair services, calibration, conversions, upgrades, refurbishments, and used equipment to companies using our products.

Critical Accounting Estimates

The preparation of consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America (“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 positions require significant judgments, assumptions, and estimates to be used in the preparation of the consolidated financial statements, actual results could differ materially from the amounts reported based on variability in factors affecting these statements.

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.

Income Taxes

We are subject to income taxes in the United States and numerous foreign jurisdictions. Significant judgment is required in determining our provision for income taxes and income tax assets and liabilities, including evaluating uncertainties in the application of accounting principles and complex tax laws. We record a provision for income taxes for the anticipated tax consequences of the reported results of operations using the asset and liability method. Under this method, we recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. We calculate tax expense consistent with intraperiod tax allocation methodology resulting in an allocation of current year tax expense/benefit between continuing operations and discontinued operations. We record a valuation allowance to reduce our deferred tax assets to the net amount that we believe is more likely than not to be realized.

We recognize tax benefits from uncertain tax positions only if we believe that it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. Although we believe that we have adequately reserved for our uncertain tax positions, we can provide no assurance that the final tax outcome of these matters will not be materially different. We adjust these reserves when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made and could have a material impact on our financial condition and operating results. The provision for income taxes includes the effects of any reserves that we believe are appropriate, as well as the related net interest and penalties. For more details see Note 5. Income Taxes in Part II, Item 8 “Financial Statements and Supplementary Data.”

Inventories

Inventories are valued at the lower of cost (using the first-in, first-out method) or net realizable value. 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.

Defined Benefit Pension Plans

Accounting for pension plans requires that we make assumptions that involve considerable judgment which are significant inputs in the actuarial models that measure our net pension obligations and ultimately impact our earnings. These include the discount rate, long-term expected rate of return on assets, compensation trends, inflation considerations, health care cost trends and other assumptions, as well as determining the fair value of assets in our funded plans. Specifically, the discount rates, as well as the expected rates of return on assets and plan asset fair value determination, are important assumptions used in determining the plans’ funded status and annual net periodic pension and benefit costs. We evaluate these critical assumptions at least annually on a plan and country-specific basis. We also, with the help of actuaries, periodically evaluate other assumptions involving demographic factors, such as retirement age, mortality, and turnover, and update them to reflect our experience and expectations for the future. We believe the accounting estimates related to our pension plans are critical accounting estimates because they are highly susceptible to change from period to period based on the performance of plan assets, actuarial valuations, market conditions and contracted benefit changes. While we believe that our assumptions are appropriate, significant differences in our actual experience or significant changes in our assumptions may materially affect our net pension and postretirement benefit obligations and related expenses.

Business Environment and Trends

Advanced Energy is organized on a global, functional basis and operates in the single segment for 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.

In April 2022, we acquired SL Power. See Note 2. Acquisitions in Part II, Item 8 “Financial Statements and Supplementary Data.” This acquisition added complementary products to Advanced Energy’s medical power offerings and extends our presence in several advanced industrial markets.

The demand environment in each of our markets is impacted by various market trends, customer buying patterns, design wins, macroeconomic and other factors. During 2022, growth in all four of our markets was strong driven by investment in new technology, capacity, and macroeconomic recovery. However, we were limited in our ability to fulfill this demand due to supply chain shortages for critical integrated circuits, resulting in longer lead times for our products. These supply constraints have led to longer lead times in procuring materials and subcomponents and, in some cases, meaningfully higher costs for the subcomponents. We have implemented measures to improve the supply of critical materials and components and to mitigate the impact of these higher input costs, and these actions have enabled us to better meet customer demand. However, it is not clear how long global supply constraint conditions will continue, how quickly the supply chain will recover, the extent to which our mitigating actions will be successful, or to what extent we can recover our higher costs. One result of the supply chain constraints is that our backlog throughout the first three quarters of the year remained above backlog at the end of 2021. Backlog declined at the end of 2022 to $875.3 million, a decrease as compared to $1,093.0 million at the end of the third quarter of 2022, driven by approximately 40% of sequential decline from China-based semiconductor customers’ orders as a result of U.S. export controls introduced in October 2022, and the remainder from lower demand and changes in ordering patterns from our semiconductor customers as we improved our lead times. Despite the decline at the end of 2022, backlog remains high compared to previous years.

COVID related disruptions did materially impact our liquidity, ability to access capital, ability to comply with our debt covenants or the fair value of our assets in 2022.

SEMICONDUCTOR EQUIPMENT MARKET

The Semiconductor Equipment market is driven by the long-term growing need for more semiconductor production capacity and new process technologies. While the semiconductor and semiconductor equipment industries are inherently cyclical, over the long-term, integrated circuits content is growing across many industries driven by increased demand for processing, storing, and transmitting the growing amount of data. To meet the growing demand, the chip industry continues to invest in production capacity for both leading-edge and trailing-edge nodes logic devices, the latest memory devices, back-end test, and advanced wafer-level packaging. The industry’s transition to advanced technology nodes and to increased layers in memory devices require an increased number of plasma-based etch and deposition process tools and higher content of our advanced power solutions per tool. As etching and deposition processes become more challenging due to shrinking device geometry and increasing aspect ratios in advanced 3D devices, more advanced RF and DC plasma generation technologies are needed. We strive to provide a broad range of best-in-class, industry-leading RF and DC power solutions. Beyond etch and deposition processes, growing complexity at advanced nodes also drives a higher number of other process steps across the wafer fab, including inspection, metrology, thermal, ion implantation, and semiconductor test and assembly, where Advanced Energy is actively participating as a critical technology provider. In addition, our global support services group offers comprehensive local repair service, upgrade, and retrofit offerings to extend the useable life of our customers’ capital equipment for additional technology generations. Our strategy in the Semiconductor Equipment market is to defend our proprietary positions in our core applications by capturing new design and product generations, growing our market position in applications where we have lower market share, such as remote plasma source and dielectric etch, and leveraging our product portfolio in areas including embedded power, high voltage power systems, and critical sensing and controls to grow our market share and content at our original OEM customers.

Table of Contents

The Semiconductor Equipment market continued to experience demand growth driven by investments in both leading and trailing edge semiconductor capacity throughout the first three quarters of 2022. Advanced Energy participated in the market growth while overcoming supply chain challenges and delivered record revenue from the Semiconductor Equipment market in 2022. Starting in the fourth quarter of 2022, the market entered a cyclical downturn due to changing macroeconomic conditions, overcapacity in the market for memory devices, general semiconductor inventory digestion resulting in falling fab utilization and reduced fab expansion plans, and new export restrictions to China for certain semiconductor equipment. These factors adversely impacted our demand, backlog, and revenue in the fourth quarter of 2022 and are expected to continue in 2023. We believe long-term drivers for demand growth in this market will eventually resume, due to the need to invest in new fab capacity to support growing demand for semiconductor devices in a wide range of applications, the continued transition to next generation processing nodes, increased complexity of advanced processes requiring more complex and innovative power solutions, and the regionalization of some semiconductor capacity.

INDUSTRIAL AND MEDICAL MARKET

Advanced Energy serves the Industrial and Medical market with mission-critical power components that deliver high reliability, precise, low noise or differentiated power to the equipment they serve. Growth in the Industrial and Medical market is driven by investment in complex manufacturing processes or automation, increased adoption of smart power, sensing, and control solutions across many industrial applications, new investments in clean and sustainable technologies, and growing investment in medical devices and life science equipment. Our customers in the Industrial and Medical market are primarily global and regional original equipment manufacturers, incorporating our advanced power, embedded power, and measurement products into a wide variety of equipment used in applications, such as advanced material fabrication, medical devices, analytical instrumentation, test and measurement equipment, robotics, industrial production, and large-scale connected light-emitting diode applications. Examples of products sold into the Industrial and Medical market include high voltage and low voltage power supplies used in applications such as medical devices, scientific instrumentation and industrial equipment, power control modules and thermal instrumentation products for material fabrication, production process control and many precision industrial sensing applications. Our strategy in the Industrial and Medical market is to expand our product offerings and channel reach, leveraging common platforms, derivatives, and customizations to further penetrate a broader set of applications.

During 2022, we saw increased demand in the Industrial and Medical market as our customers increased investments in their production capacity and the medical technology industry recovered from the pandemic-related slowdown. Although overall customer demand increased, supply constraints of critical components limited our ability to fulfill product shipments at the level of customer demand and resulted in increased backlog. Going into 2023, we expect product delivery and revenue levels will depend on the level of customers’ demand and on resolving supply chain constraints. It is not clear how long these supply chain constraints will persist or on what timeline our supply chain will recover.

DATA CENTER COMPUTING MARKET

Advanced Energy serves the Data Center Computing market with industry leading power conversion products and technologies, which we sell to OEMs and original design manufacturers (“ODMs”) of data center server and storage systems, as well as cloud service providers and their partners. Driven by the growing adoption of cloud computing, market demand for server and storage equipment has shifted from traditional enterprise on-premises computing to the data center, driving investments in data center infrastructure. Beyond the cloud, demand for edge computing is also growing, driven by the need for faster processing, lower latency, and higher data security at edge applications. In addition, the data center industry has begun transitioning from 12 Volt to 48 Volt infrastructure in data center server racks to improve overall power efficiency. Advanced Energy benefits from these trends by being an industry leader in providing high-efficiency 48 Volt server power solutions to the data center industry. Further, the rapid growth and adoption of artificial intelligence and machine learning are driving accelerated demand for server and storage racks with increased power density and higher efficiency, which complements Advanced Energy’s strengths. With a growing presence at both cloud service providers and industry-leading data center server and storage vendors, our strategy in the Data Center and Computing market is to penetrate selected customers and applications based on our differentiated capability and competitive strengths in power density, efficiency, and controls.

Table of Contents

Customer demand for our products rose during 2022 with continued demand for cloud and network applications. In addition, we were able to secure additional critical components compared to the prior year, allowing us to deliver higher revenue in the Data Center Computing market. Despite the improved performance, the supply of the critical components remains highly constrained, impacting our ability to fulfill product shipments at the level of customer demand. Although we expect lower overall demand in 2023 as cloud and enterprise customers slow investments to digest capacity investments, we continue to be supply constrained and our performance will be partially dependent on our ability to secure critical components and customers’ timing of new programs. It is not clear how long these supply chain constraints will persist or how quickly our supply chain will recover.

TELECOM AND NETWORKING MARKET

Our customers in the Telecom and Networking market include many leading vendors of wireless infrastructure equipment, telecommunication equipment and computer networking. The wireless telecom market continues to evolve with more advanced mobile standards. 5G wireless technology promises to drive substantial growth opportunities for the telecom industry as it enables new advanced applications such as autonomous vehicles and virtual/augmented reality. Telecom service providers are investing in 5G infrastructure, and this trend is expected to drive demand for our products into the Telecom and Networking market. In datacom, demand is driven by networking investments by telecom service providers and enterprises upgrading their networks, as well as cloud service providers and data centers investing in their networks for increased bandwidth. Our strategy in the Telecom and Networking market is to optimize our portfolio of products to more differentiated applications, and to focus on 5G infrastructure applications.

Revenues in the Telecom and Networking market increased in 2022 compared to the same period in the prior year due to increased customer demand and our ability to secure additional critical components. We expect demand to remain stable in this market in 2023, but supply chain constraints continue to prevent us from fulfilling product shipments at the level of customer demand. It is not clear how long these supply shortages will persist or how quickly our supply chain will recover.

SALES AND BACKLOG

Sales

Sales increased $389.5 million, or 26.8%, to $1,845.4 million, as compared to $1,456.0 million in the prior year. The increase in sales was primarily due to increased demand for our products across all four of our markets and measures we took to improve material availability and capacity, which allowed us to better meet higher demand. In addition, premium recoveries, which are revenues we collected from our customers to partially reimburse us for premiums we paid to secure scarce materials, represented $68.3 million in revenue in 2022 compared to $14.3 million in 2021. The acquisition of SL Power contributed $50.3 million to our total sales in 2022. For additional information, see Note 2. Acquisitions in Part II, Item 8 “Financial Statements and Supplementary Data.”

Backlog

The following table summarizes our backlog (in thousands):

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | December 31, | ​ | December 31, | ​ | Change from Year End | ​
​ |  | 2022 |  | 2021 |  | Dollar |  | Percent | ​
Backlog | ​ | $ | 875,346 | ​ | $ | 927,810 | ​ | $ | (52,464) | ​ | (5.7) | %

​

Backlog represents outstanding orders for products we expect to deliver within the next 12 months. Backlog at the end of 2022 decreased from the end of 2021 primarily due to the impact of the China export controls regulation announced in October 2022 by the U.S. Commerce Department, lower demand in the Semiconductor Equipment market, and changes in order patterns for our semiconductor customers as we improved lead times, which occurred in the fourth quarter of 2022. Backlog in our other markets increased for the year.

We believe the current backlog levels provide some level of revenue protection if demand levels are reduced due to macroeconomic factors. We expect to bring our backlog back into normalized levels of $400 million to $500 million over the next several quarters as parts availability improves and lead times are reduced.

Backlog at any particular date is not necessarily indicative of actual sales which may be generated for any succeeding period. In addition, there is uncertainty of the timing of when backlog can convert into revenue due to continuing supply constraints. Because our customers generally order on a purchase order basis, they can typically cancel, change, or delay product purchase commitments with little or no notice.

Sales by Market

Sales in the Semiconductor Equipment market increased $220.6 million, or 31.1%, to $930.8 million, as compared to $710.2 million in the prior year. The increase in sales was primarily due to the growth in the Semiconductor Equipment market, particularly highlighted by the 40% increase in sales to our top two customers who are primarily in this market. In addition, we improved our ability to secure critical components and increased delivery to our customers in this market.

Sales in the Industrial and Medical market increased $85.6 million, or 25.1%, to $426.8 million, as compared to $341.2 million in the prior year. The increase in sales was primarily due to the acquisition of SL Power, which added incremental sales of $46.5 million in this market. The remainder of the increase in revenue was due to increased demand for our portfolio of products across our medical and industrial applications and improved material availability.

Sales in the Data Center Computing market increased $56.5 million, or 20.9%, to $327.5 million, as compared to $270.9 million in the prior year. The increase in Data Center Computing market sales was due to better supply availability, enabling us to partially fulfill product shipments against higher customer demand.

Sales in the Telecom and Networking market increased $26.7 million, or 20.0%, to $160.4 million as compared to $133.7 million in the prior year. The increase in sales was primarily due to improved material availability, allowing us to meet the increased demand.

​

GROSS PROFIT AND GROSS MARGIN

Gross profit dollars in 2022 increased by $143.2 million to $675.5 million, or 36.6% of revenue, as compared to prior year’s $532.3 million, or 36.6% of revenue, primarily driven by higher revenue.

Gross margin percentage remained flat year over year as the benefit of higher volume and favorable mix was offset primarily by higher material costs related to premiums paid to brokers for scarce parts. Premium recoveries, which represent revenue at zero gross margin, impacted gross margins by approximately 140 basis points, compared to approximately 35 basis points in the prior year. Additionally, higher material costs not recovered impacted gross margins

36

Table of Contents

by approximately 200 basis points, compared to approximately five basis points in the prior year. We expect that the amount of higher material costs and related recoveries will abate as the supply chain normalizes and scarce parts become more available from original manufacturers.

OPERATING EXPENSE

Research and Development

We perform R&D of products to develop new or emerging applications, technological advances to provide higher performance, lower cost, or other attributes that we may expect to advance our customers’ products. We believe that continued development of technological applications, as well as enhancements to existing products and related software to support customer requirements, are critical for us to compete in the markets we serve. Accordingly, we devote significant personnel and financial resources to the development of new products and the enhancement of existing products, and we expect these investments to continue.

R&D expenses increased $29.2 million to $191.0 million, as compared to $161.8 million in the prior year. The increase in research and development expense is primarily driven by increased headcount and compensation costs of $20.4 million, as we invest in new programs to maintain and increase our technological leadership and provide solutions to our customers’ evolving needs.

Selling, General and Administrative

Our selling expenses support domestic and international sales and marketing activities that include personnel, trade shows, advertising, third-party sales representative commissions, and other selling and marketing activities. Our general and administrative expenses support our worldwide corporate, legal, tax, financial, governance, administrative, information systems, and human resource functions in addition to our general management, including acquisition related activities.

Selling, general and administrative (“SG&A”) expenses increased $26.5 million to $218.5 million, as compared to $192.0 million in the prior year. The increase in SG&A is primarily related to $16.9 million from increased headcount and associated costs including sales commissions and compensation driven by higher revenue and $6.0 million from the addition of SL Power. See Note 2. Acquisitions in Part II, Item 8 “Financial Statements and Supplementary Data” for additional details.

Amortization of Intangibles

Amortization expense increased $4.1 million to $26.1 million, as compared to $22.1 million in the prior year. The increase was primarily driven by incremental amortization of newly acquired intangible assets from the SL Power acquisition. For additional information, see Note 2. Acquisitions and Note 13. Intangible Assets in Part II, Item 8 “Financial Statements and Supplementary Data.”

Restructuring

In the fourth quarter of 2022, management approved a restructuring plan (the “2022 Plan”), which is expected to further 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, and reducing redundancies. The majority of these actions impact our factory operations and should partially mitigate the impact of lower volumes on gross margins. We anticipate the 2022 Plan will be substantially completed, and associated expenses will be incurred by 2024.

In 2018, we committed to a restructuring plan (the “2018 Plan”) to optimize our manufacturing footprint and to improve our operating efficiencies and synergies related to business combinations. We incurred severance costs primarily related to the transition and exit of our facility in Shenzhen, China and actions associated with synergies related to the acquisition of Artesyn Embedded Technologies, Inc.’s embedded power business (“Artesyn”). This plan is

Table of Contents

substantially complete with the closure of our Shenzhen facility expected in 2023. For additional information, see Note 14. Restructuring Costs in Part II, Item 8 “Financial Statements and Supplementary Data.”

Other Income (Expense), net

Other income (expense), net consists primarily of interest income and expense, foreign exchange gains and losses, gains and losses on sales of fixed assets, and other miscellaneous items.

​

Other income (expense), net was $8.6 million in 2022, as compared to ($3.0) million in the prior year. The increase in income between periods is primarily a result of higher unrealized foreign exchange gains of $4.2 million due to the strengthening U.S. dollar compared to our other foreign currencies and a one-time gain on the sale of intellectual property from a previous acquisition. This was partially offset by higher interest expenses because of increasing interest rates.

Provision for Income Taxes

Provision for income taxes | ​ | $ | 39,850 | ​ | $ | 14,004 | ​
Effective tax rate | ​ | ​ | 16.5 | % | ​ | 9.4 | %

​

Our effective tax rate increased in 2022 compared to 2021, primarily driven by a change in tax law from the 2017 Tax Cuts and Jobs Act related to the capitalization of R&D expenses, as it impacts the net U.S. tax on foreign operations, that went into effect in January 2022, offset by the benefit of earnings in foreign jurisdictions which are subject to lower tax rates.

The Inflation Reduction Act (“IRA”) and CHIPS and Science Act (“CHIPS Act”) were both enacted in August 2022. The IRA introduced new provisions including a 15% corporate alternative minimum tax for certain large corporations that have at least an average of $1 billion adjusted financial statement income over a consecutive three-tax-year period and a 1% excise tax surcharge on stock repurchases. The CHIPS Act provides a variety of incentives associated with investments in domestic semiconductor manufacturing and related activities. The IRA and the CHIPS Act are applicable for tax years beginning after December 31, 2022 and had no benefit to our consolidated financial statements for any of the periods presented, and we do not expect them to have a direct material impact on our future results of operations, financial condition, or cash flows.

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.

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, 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 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.

Table of Contents

The non-GAAP results presented below exclude the impact of non-cash related charges, such as stock-based compensation and amortization of intangible assets. In addition, they exclude discontinued operations and other non-recurring items such as acquisition-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 and effect of adoption of the 2017 Tax Cuts and Jobs Act.

Impact of Inflation

In previous years, inflation did not have a material impact on our operations. However, more recently, we have experienced inflationary pressure from price increases in select components driven by factors such as higher global demand, supply chain disruptions, higher labor expenses, and increased freight costs. In this environment, we are actively working with our customers to adjust pricing that helps offset the inflationary pressure on the cost of our components. We have also been able to recover some premiums on pricing related to securing scarce materials with our customers, thus limiting the financial impact of inflationary pressures.

Liquidity and Capital Resources

Liquidity

We believe that adequate liquidity and cash generation is 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 are our available cash, investments, cash generated from current operations, and available borrowing capacity under the Revolving Facility (defined below).

The following table summarizes our cash, cash equivalents, and marketable securities (in thousands):

​ | ​ | ​ | ​
​ | ​ | December 31, 2022
Cash and cash equivalents | ​ | $ | 458,818
Marketable securities | ​ |  | 2,128
Total cash, cash equivalents, and marketable securities | ​ | $ | 460,946

​

We believe the above sources of liquidity will be adequate to meet anticipated working capital needs, anticipated levels of capital expenditures, contractual obligations, debt repayment, share repurchase programs, and dividends for the next 12 months and on a long-term basis. In addition, we may, depending upon the number or size of additional acquisitions, seek additional debt or equity financing from time to time; however, such additional financing may not be available on acceptable terms, if at all.

Credit Facility

In September 2019, in connection with the acquisition of Artesyn, we entered into a credit agreement (“Credit Agreement”) that provided aggregate financing of $500.0 million, consisting of a $350.0 million senior unsecured term loan facility (the “Term Loan Facility”) and a $150.0 million senior unsecured revolving facility (the “Revolving Facility” and together with the Term Loan Facility, the “Credit Facility”).

In April 2020, we executed interest rate swap contracts with independent financial institutions to partially reduce the variability of cash flows in LIBOR indexed debt interest payments on our Term Loan Facility. The interest rate swap contracts fixed a portion of the outstanding principal balance on our term loan to a total interest rate of 1.271%. For information additional information, see Note 8. Derivative Financial Instruments in Part II, Item 8 “Financial Statements and Supplementary Data.”

In September 2021, we amended the Credit Agreement whereby we borrowed an additional $85.0 million, which increased the aggregate amount outstanding under the Term Loan Facility to $400.0 million. In addition, we increased the Revolving Facility capacity by $50.0 million to $200.0 million. Both the Term Loan Facility and Revolving Facility mature on September 9, 2026.

​

As of December 31, 2022, we had $200.0 million in available funding under the Revolving Facility. The Term Loan Facility requires quarterly repayments of $5.0 million plus accrued interest, with the remaining balance due in September 2026.

In addition to the available capacity on the Revolving Facility, prior to the maturity date of our Credit Agreement, we may also 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 at identical terms to our existing Credit Facility.

For additional information on our Credit Facility, see Note 21. Credit Facility in Part II, Item 8 “Financial Statements and Supplementary Data.”

Dividends

In March 2021, the Board of Directors (the “Board”) declared the first quarterly cash dividend since our inception as a public company. During 2022, we paid quarterly cash dividends of $0.10 per share, totaling $15.2 million for the full year. 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 and will depend on our financial condition, results of operations, capital requirements, business conditions, and other factors.

Share Repurchases

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

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Years Ended December 31,

Average repurchase price per share | ​ | $ | 74.90 | ​ | $ | 86.76 | ​ | $ | 47.75

​

In July 2022, the Board of Directors approved an increase to the share repurchase plan that increased the remaining amount authorized for future repurchases to a maximum of $200.0 million with no time limitation. At December 31, 2022, the remaining amount authorized by the Board of Directors for future share repurchases was $199.3 million.

​

Net Cash From Operating Activities

Net cash from operating activities from continuing operations was $183.7 million, an increase of $42.8 million, compared to $140.9 million in the prior year. The increase is primarily due to an increase in net income. This was partially offset by an unfavorable increase in net operating assets driven primarily by an increase in accounts receivable due to our strong revenue growth.

Net Cash From Investing Activities

Net cash from investing activities in 2022 was ($208.3) million, driven by the following:

| ● | ($58.9) million in purchases of property and equipment as we invested in our manufacturing footprint and capacity; and

| ● | ($149.4) million for business combinations.

Net cash from investing activities in 2021 was ($47.3) million, and primarily related to investment in facilities and capacity.

Net Cash From Financing Activities

Net cash from financing activities in 2022 was ($61.9) million and included:

| ● | ($15.2) million for dividend payments;

| ● | ($20.0) million for repayment of long-term debt; and

| ● | ($26.6) million related to repurchases of our common stock.

The net cash from financing activities in 2021 was ($25.4) million and included:

| ● | $83.7 million in proceeds from borrowings, net of debt-issuance costs paid;

| ● | ($15.4) million for dividend payments;

| ● | ($13.8) million for repayment of long-term debt;

42

Table of Contents

| ● | ($78.1) million related to repurchases of our common stock; and

| ● | ($1.8) million related to stock-based award activities.

Off-Balance Sheet Arrangements

As of December 31, 2022, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of 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 are provided in Note 5. Income Taxes, Note 16. Leases, Note 17. Employee Retirement Plans and Postretirement Benefits, and Note 21. Credit Facility, respectively, in Part II, Item 8 “Financial Statements and Supplementary Data.”

Recent Accounting Pronouncements

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, is not expected to have a material impact on our consolidated financial statements upon adoption.

To understand the impact of recently issued guidance, 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 Facility. 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 sales 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.

The functional currencies of our worldwide facilities primarily include the United States Dollar (USD), Euro, South Korean Won, New Taiwan Dollar, Japanese Yen, Pound Sterling, Chinese Yuan, and Mexican Peso. Our purchasing and sales activities are primarily denominated in the USD, Japanese Yen, Euro, and Chinese Yuan.

43

Table of Contents

Currency exchange rates vary daily and often one currency strengthens against the USD while another currency weakens. Because of the complex interrelationship of the worldwide supply chains and distribution channels, it is difficult to quantify the impact of a change in one or more particular exchange rates.

As currencies fluctuate against each other we are exposed to foreign currency exchange rate risk on sales, purchasing transactions, and labor. Exchange rate fluctuations could require us to increase prices to foreign customers, which could result in lower net sales. Alternatively, if we do not adjust the prices for our products in response to unfavorable currency fluctuations, our results of operations could be adversely impacted. Changes in the relative buying power of our customers may impact sales volumes.

Acquisitions are a large component of our capital deployment strategy. A significant number of acquisition target opportunities are located outside the U.S., and their value may be denominated in foreign currency. Changes in exchange rates therefore may have a material impact on their valuation in USD and may impact our view of their attractiveness.

​

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

Our market risk exposure relates primarily to changes in interest rates on our Credit Facility. The following table summarizes borrowings (in thousands) under our Credit Facility and the associated interest rate.

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | December 31, 2022
​ | ​ | Balance |  | Interest Rate |  | Unused Line Fee
Term Loan Facility subject to a fixed interest rate | ​ | $ | 238,219 | ​ | 1.271% | ​ | —
Term Loan Facility subject to a variable interest rate | ​ | ​ | 136,781 | ​ | 5.134% | ​ | —
Revolving Facility subject to a variable interest rate | ​ | ​ | — | ​ | 5.134% | ​ | 0.10%
Total borrowings under the Credit Agreement | ​ | $ | 375,000 | ​ | ​ | ​ | ​

​

For more information on the Term Loan Facility see Note 21. Credit Facility in Part II, Item 8 “Financial Statements and Supplementary Data.” For more information on the interest rate swap that fixes the interest rate for a portion of our Term Loan Facility, see Note 8. Derivative Financial Instruments in Part II, Item 8 “Financial Statements and Supplementary Data.” The Term Loan Facility and Revolving Facility bear interest, at our option, at a rate based on a reserve adjusted “Eurodollar Rate” or “Base Rate,” as defined in the Credit Agreement, plus an applicable margin.

Our interest payments are impacted by interest rate fluctuations. With respect to the portion of our Credit Facility that is subject a variable interest rate, a hypothetical increase of 100 basis points (1%) in interest rates would have a $1.4 million annual impact on our interest expense. A change in interest rates does not have a material impact upon our future earnings and cash flow for fixed rate debt. However, increases in interest rates could impact our ability to refinance existing maturities and acquire additional debt on favorable terms.

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, 2022 and 2021, 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, 2022, 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, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, 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, 2022, 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 17, 2023 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.

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 10 to the consolidated financial statements, the Company has inventories with a carrying value of $376.0 million as of December 31, 2022. 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 end-user 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 a high degree of judgment because a critical factor in determining excess and obsolete inventory requires management to determine projected end-user 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 end-user demand. We evaluated certain inventories for excess or obsolescence by testing key inputs, including historical usage and projected end-user 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 end-user 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.

Opinion on Internal Control Over Financial Reporting

We have audited Advanced Energy Industries, Inc.’s internal control over financial reporting as of December 31, 2022, 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, 2022, based on the COSO criteria.

As indicated in the accompanying Management’s Annual Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of SL Power Electronics, which is included in the 2022 consolidated financial statements of the Company and constituted 2% and 3% of total and net assets, respectively, as of December 31, 2022 and 3% and 3% of revenues and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of SL Power Electronics.

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, 2022 and 2021, 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, 2022, and the related notes and our report dated February 17, 2023 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.

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.

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”) 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.

Our plasma power solutions enable innovation in complex semiconductor and thin film plasma processes such as dry etch and deposition. Our broad portfolio of high and low voltage power products are used in a wide range of applications, such as semiconductor equipment, industrial production, medical and life science equipment, data centers computing, networking, and telecommunications. We also supply related sensing, controls, and instrumentation products primarily for advanced measurement and calibration of power and temperature for multiple industrial markets. Our network of global service support centers provides repair services, calibration, conversions, upgrades, refurbishments, and used equipment to companies using our products.

As of December 31, 2015, we discontinued our engineering, production, and sales of our inverter product line. As such, all inverter product revenues, costs, assets, and liabilities are reported in Discontinued Operations for all periods presented herein. See Note 4. Discontinued Operations for more information. Ongoing inverter repair and service operations are reported as part of our continuing 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”). We reclassified certain prior period amounts to conform to the current year presentation.

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; ● pension obligations; | ● acquisitions and asset valuations, and ● income taxes and other provisions.

​

Segment Information — Our Chief Executive Officer 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.

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 and interest rate fluctuations. 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.

For derivatives designated as cash flow hedges, changes in fair value are recorded to accumulated other comprehensive income (loss) on the Consolidated Balance Sheets and are reclassified into earnings when the underlying forecasted transaction affects earnings. We reassess the probability of the underlying forecasted transactions occurring on a quarterly basis.

Fair Value — We value our 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.

We have various assets and liabilities measured at fair value on a recurring basis, including:

Foreign currency forward contracts

We estimate the fair value based on the movement in the forward rates of foreign currency cash flows in which the hedging instrument is denominated.

Interest rate swaps

We determine the fair value by estimating the net present value of the expected cash flows based on market rates and the associated yield curves, adjusted for non-performance credit risk, as applicable.

Contingent consideration associated with business combinations

We determine the fair value by estimating the net present value of the expected cash flows based on the probability of expected payment.

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.

56

Table of Contents

ADVANCED ENERGY INDUSTRIES, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued)
(in thousands, except per share amounts)

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 12. Goodwill and Note 13. Intangible Assets for further discussion and presentation of these amounts.

The fair value of borrowings approximates the recorded borrowing value based upon market interest rates for similar facilities. See Note 21. Credit Facility for additional information. The fair value of contingent consideration and other acquired assets and liabilities associated with our acquisitions are based on Level 3 inputs.

Cash, Cash Equivalents, and Marketable Securities — 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. We believe 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 record interest income within other income (expense), net in our Consolidated Statement of Operations.

We classify investments with stated maturities of greater than three months at time of purchase as marketable securities.

Concentrations of Credit Risk — Financial instruments with potential credit risk include cash and cash equivalents, marketable securities, 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.

We establish a reserve for credit losses based upon factors surrounding the credit risk of specific customers, historical trends, and other information.

Accounts Receivable and Reserve for Credit Losses — Accounts receivable are recorded at net realizable value. We maintain a credit approval process and we make judgments in connection with assessing our customers’ ability to pay. Despite this assessment, from time to time, our customers are unable to meet their payment obligations. We continuously monitor our customers’ credit worthiness and use our judgment in establishing a provision for estimated credit losses. We do not require collateral from customers. Our principal customers are original equipment manufacturers (“OEM”) and end user customers, which operate globally through wholly owned subsidiaries that purchase our products under substantially the same credit terms, with similar historical credit risks. As a result, we assess credit risks as a single group. We evaluate collection risk and establish expected credit loss primarily through a combination of the following: an assessment of customer credit risk ratings utilizing third party credit risk data, analysis of historical aging and credit loss experience, and customer specific information.

Inventories — Inventories are valued at the lower of cost (using the first-in, first-out method) or net realizable value. 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

57

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued)
(in thousands, except per share amounts)

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. Depreciation is computed over the estimated useful lives using the straight-line method. Additions and improvements are capitalized, while maintenance and repairs are expensed as incurred.

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.

Business Combinations — Business combinations are accounted for using the purchase method of accounting. Under the purchase method, assets and liabilities, including intangible assets, are recorded at their fair values as of the acquisition date. Acquisition costs in excess of amounts assigned to assets acquired and liabilities assumed are recorded as goodwill. Transaction related costs associated with business combinations are expensed as incurred.

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.

Intangible Assets, Goodwill, and Other Long-Lived Assets — As a result of our acquisitions, we identified and recorded intangible assets and goodwill. Intangible assets are valued based on estimates of future cash flows and amortized over their estimated useful lives. Goodwill is subject to annual impairment testing, as well as testing upon the occurrence of any event that indicates a potential impairment. Intangible assets and other long-lived assets are subject to an impairment test if there is an indicator of impairment. The carrying value and ultimate realization of these assets is dependent upon our estimates of future earnings and benefits that we expect to generate from their use. If our expectations of future results and cash flows are significantly diminished, intangible assets and goodwill may be impaired and the resulting charge to operations may be material. When we determine that the carrying value of intangibles or other long-lived assets may not be recoverable based upon the existence of one or more indicators of impairment, we use the projected undiscounted cash flow method to determine whether an impairment exists, and then measure the impairment using discounted cash flows.

The estimation of useful lives and expected cash flows requires us to make judgments regarding future periods that are subject to some factors outside of our control. Changes in these estimates can result in revisions to our carrying value of these assets and may result in material charges to our results of operations.

(in thousands, except per share amounts)

We conduct an annual goodwill impairment analysis using an assessment of qualitative factors in determining if it is more likely than not that goodwill is impaired. If this assessment indicates that it is more likely than not that goodwill is impaired, the next step of impairment testing compares the fair value of a reporting unit to its carrying value. Goodwill would be impaired if the resulting implied fair value of goodwill was less than the recorded carrying value of the goodwill.

Debt Issuance Costs — We incurred debt issuance costs in connection with our debt facilities. Amounts paid directly to lenders are classified as issuance costs. Commitment fees and other costs directly associated with obtaining credit facilities are classified as deferred financing costs, which are recorded in the Consolidated Balance Sheets and amortized over the term of the debt facility. We allocated deferred debt issuance costs incurred for the current credit facility between the revolver and term loan based on their relative borrowing capacity. Deferred debt issuance costs associated with the revolving credit facility are recorded within other assets and those associated with the term loan are recorded as a reduction of the carrying value of the debt on the Consolidated Balance Sheets. We amortize the majority of deferred debt issuance costs to interest expense using the effective interest rate method. Deferred debt issuance costs on the line of credit are amortized on the straight-line basis over the life of the debt agreement. Amortization of debt issuance costs is reflected in other income (expense), net on the Consolidated Statements of Operations. See Note 21. Credit Facility for additional details.

Revenue Recognition — Net sales consist of revenue from the sale 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. Revenue is recognized 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 sales. 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. Payment terms for customers’ extended credit are typically net 30 days.

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 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, which had previously been offered on our discontinued inverter products. Any up-front fees received for extended warranties or maintenance plans are deferred. 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.

Research and Development Expenses — Costs incurred to advance, test, or otherwise modify our proprietary 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.

Warranty Costs — We provide for the estimated costs to fulfill customer warranty obligations upon the recognition of the related revenue. We offer warranty coverage for a majority of our precision power products for periods typically ranging from 12 to 24 months after shipment. We warranted our inverter products for five to ten years and provided the option to purchase additional warranty coverage for up to 20 years. The warranty expense accrued

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued)

related to our standard inverter product warranties is now considered part of our discontinued operations and is recorded as such on our Consolidated Balance Sheets. See Note 4. Discontinued Operations for more information. See Note 15. Warranties for more information on our warranties from continuing operations. We estimate the anticipated costs of repairing our products under such warranties based on the historical costs of the repairs. The assumptions we use to estimate warranty accruals are reevaluated periodically, considering actual experience, and when appropriate, the accruals are adjusted. Should product failure rates differ from our estimates, actual costs could vary significantly from our expectations.

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 utilize the Black-Scholes Merton option pricing model to estimate the fair value of stock options and Employee Stock Purchase Plan (“ESPP”) purchase rights. This model requires various estimates and assumptions, including:

Fair value of the common stock

We use the market closing price of our common stock, as reported on the NASDAQ Exchange.

​

Expected term

The expected term is based on historical experience and represents the period we expect the stock option or ESPP purchase right to be outstanding.

​

Expected volatility

We derive the expected volatility from the historical volatility of our common stock over a period equivalent to the expected term.

​

Risk -free interest rate

We obtain the risk-free interest rate from the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the expected term of the stock-based award.

​

Expected dividend

The expected dividend is based on the assumption that future dividend payments will follow recent historical practice.

​

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 management’s assessment of the probability of meeting the performance conditions) over the estimated period to achieve the performance conditions. Upon forfeiture or expiration of these awards, we reverse the stock-based compensation expense.

Certain RSUs vest based on a market condition. We estimate the fair value and probability of achievement for each tranche of these awards using a Monte Carlo simulation. Because the probability of achievement is a factor in the Monte Carlo simulation, 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.

(in thousands, except per share amounts)

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 realize the benefits of these deductible differences.

Accounting for income taxes requires a two-step approach to recognize and measure uncertain tax positions. In general, we are subject to regular examination of our income tax returns by the Internal Revenue Service and other tax authorities. 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 — From time to time 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 in a particular period. An unfavorable decision, particularly in patent litigation, 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 patent rights. We accrue loss contingencies when it is probable that a loss has occurred or will occur, and the amount of the loss can be reasonably estimated. Our estimates of probability of losses are subjective, involve significant judgment and uncertainties, and are based on the best information we have at any given point in time. Resolution of these uncertainties in a manner inconsistent with our expectations could have a significant impact on our results of operations and financial condition.

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.

(in thousands, except per share amounts)

New Accounting Standards Adopted

In October 2021, the FASB issued ASU 2021-08, “Business Combinations (Topic 806) Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” The amendments in ASU 2021-08 address diversity and inconsistency related to the recognition and measurement of contract assets and contract liabilities acquired in a business combination. ASU 2021-08 requires an acquirer to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers.

We adopted ASU 2021-08 on a prospective basis effective January 1, 2022. The adoption will impact business combinations subsequent to that date and require recognition and measurement of acquired contract assets and liabilities in accordance with ASC 606. Specifically, we will account for the related revenue contracts of the acquiree as if we originated the contracts. Adoption of ASU 2021-08 did not impact acquired contract assets or liabilities from prior business combinations.

New Accounting Standards Issued But Not Yet Adopted

The FASB issued the following ASUs:

​

Issuance Date | ASU | Title
March 2020 | 2020-04 | Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ​
January 2021 | 2021-01 | Reference Rate Reform (Topic 848): Scope ​
December 2022 ​ | 2022-06 | Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848

​

This collective guidance provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria that reference LIBOR or another reference rate that is expected to be discontinued. The above accounting standards will be in effect through December 31, 2024.

​

Our Credit Facility (refer to Note 21. Credit Facility) and interest rate swap agreements (refer to Note 8. Derivative Financial Instruments) reference the one-month USD LIBOR rate. Both agreements contain provisions for transition to a new reference rate upon discontinuance of LIBOR. We expect the one-month USD LIBOR rate to be available through June 2023. We are currently assessing the potential timing of transitioning to a replacement interest rate benchmark for our Credit Facility (refer to Note 21. Credit Facility) and do not expect the above guidance to materially impact our consolidated financial statements.

NOTE 2. ACQUISITIONS

SL Power Electronics Corporation

On April 25, 2022, we acquired 100% of the issued and outstanding shares of capital stock of SL Power Electronics Corporation (“SL Power”), which is based in Calabasas, California. We accounted for this transaction as a business combination. This acquisition added complementary products to Advanced Energy’s medical power offerings and extends our presence in several advanced industrial markets.

NOTE 4. DISCONTINUED OPERATIONS

In December 2015, we completed the wind down of engineering, manufacturing, and sales of our solar inverter product line. Accordingly, the results of our inverter business are reflected as income (loss) from discontinued operations, net of income taxes on our Consolidated Statements of Operations.

We defer revenue associated with sales of extended inverter warranties and include them within customer deposits and other in our Consolidated Balance Sheets. Deferred revenue for extended inverter warranties and the associated costs of warranty service will be reflected in Sales and Cost of goods sold, respectively, from continuing operations in future periods in our Consolidated Statement of Operations as the deferred revenue is earned and the associated services are rendered. We no longer offer extended warranties related to the inverter product line.

​

Our effective tax rate increased in 2022 compared to 2021, primarily driven by a change in tax law from the 2017 Tax Cuts and Jobs Act related to the capitalization of R&D expenses, as it impacts the net U.S. tax on foreign operations, that went into effect in January 2022, offset by the benefit of earnings in foreign jurisdictions which are subject to lower tax rates.

​

Our effective tax rate decreased in 2021 compared to 2020, primarily driven by one-time tax benefits due to reductions in uncertain tax positions and increased tax credits.

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:

As of December 31, 2022, we have recorded a 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 $33.1 million and is associated primarily with operations in Germany, Hong Kong, and Switzerland. As of December 31, 2022, there is not sufficient positive evidence to conclude that such deferred tax assets, presently reduced by a valuation allowance, will be recognized. The December 31, 2022 valuation allowance balance reflects a decrease of $6.0 million during the year. The change in the valuation allowance is primarily due to decreases from foreign exchange movements and current year activity.

As of December 31, 2022, we had U.S., foreign and state tax loss carryforwards of $45.2 million, $120.1 million, and $106.5 million, respectively. Additionally, we had $0.7 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 $0.9 million and $1.9 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 $8.0 million of the federal net operating loss carry forwards, have no expiration period.

We operate under a tax holiday in Singapore and China. These tax holidays are in effect through June 30, 2027 and December 31, 2022, respectively. The tax holiday is conditional upon our meeting certain employment and investment thresholds. The impact of the tax holidays decreased foreign taxes by $19.4 million and $13.3 million for 2022 and 2021, respectively. The benefit of the tax holiday on earnings per diluted share was $0.52 and $0.35 for 2022 and 2021, respectively.

As of December 31, 2022, we have undistributed earnings in certain foreign subsidiaries of approximately $33.3 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:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Years Ended December 31,
​ |  | 2022 |  | 2021 |  | 2020

Balance at end of period | ​ | $ | 7,467 | ​ | $ | 5,513 | ​ | $ | 9,673

​

The unrecognized tax benefits of $7.5 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 $0.6 million and $0.4 million of accrued interest and penalties on December 31, 2022

and 2021, respectively. With few exceptions, we are no longer subject to federal, state, or foreign income tax examinations by tax authorities for years before 2019.

​

The Inflation Reduction Act (“IRA”) and CHIPS and Science Act (“CHIPS Act”) were both enacted in August 2022. The IRA introduced new provisions including a 15% corporate alternative minimum tax for certain large corporations that have at least an average of $1 billion adjusted financial statement income over a consecutive three-tax-year period and a 1% excise tax surcharge on stock repurchases. The CHIPS Act provides a variety of incentives associated with investments in domestic semiconductor manufacturing and related activities. The IRA and the CHIPS Act are applicable for tax years beginning after December 31, 2022 and had no benefit to our consolidated financial statements for any of the periods presented, and we do not expect them to have a direct material impact on our future results of operations, financial condition, or cash flows.

​

NOTE 6. EARNINGS PER SHARE

We compute basic earnings per share (“EPS”) by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. The diluted EPS computation is similar to basic EPS except we increase the denominator to include the number of additional common shares that would have been outstanding (using the if-converted and treasury stock methods) if our outstanding stock options and restricted stock units had been converted to common shares (when such conversion is dilutive).

The following table summarizes our earnings per share:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​ |  | 2022 |  | 2021 |  | 2020

There were no shares repurchased from related parties. Repurchased shares were retired and assumed the status of authorized and unissued shares.

In July 2022, the Board of Directors approved an increase to the share repurchase plan that increased the remaining amount authorized for future repurchases to a maximum of $200.0 million with no time limitation. At December 31, 2022, the remaining amount authorized by the Board of Directors for future share repurchases was $199.3 million.

NOTE 8. DERIVATIVE FINANCIAL INSTRUMENTS

Changes in foreign currency exchange rates impact us. 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; however, they do partially offset the economic fluctuations of certain of our assets and liabilities due to foreign exchange rate changes.

Gains and losses related to foreign currency exchange contracts were offset by corresponding gains and losses on the revaluation of the underlying assets and liabilities. Both are included as a component of other income (expense),

(in thousands, except per share amounts)

net in our Consolidated Statements of Operations. As of December 31, 2022 and 2021, there were no foreign currency forward contracts outstanding.

In April 2020, we executed interest rate swap contracts with independent financial institutions to partially reduce the variability of cash flows in LIBOR indexed debt interest payments on our Term Loan Facility (under our existing Credit Agreement dated September 10, 2019, as amended). These transactions are accounted for as cash flow hedging instruments.

The interest rate swap contracts fixed a portion of the outstanding principal balance on our term loan to a total interest rate of 1.271%. This is comprised of an 0.521% average fixed rate per annum in exchange for a variable interest rate based on one-month USD-LIBOR-BBA plus the credit spread in our existing Credit Agreement (see Note 21. Credit Facility), which is 75 basis points at current leverage ratios.

The following table summarizes the notional amount of our qualified hedging instruments:

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | December 31, | ​ | December 31,
​ |  | 2022 |  | 2021
Interest rate swap contracts | ​ | $ | 238,219 | ​ | $ | 255,719

​

The following table summarizes the amounts recorded in accumulated other comprehensive income (loss) on the Consolidated Balance Sheets for qualifying hedges.

​ |  | 2022 |  | 2021
Interest rate swap contract gains | ​ | $ | 11,779 | ​ | $ | 2,107

​

See Note 7. 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 9. ACCOUNTS AND OTHER RECEIVABLE, NET

We record accounts and other receivable at net realizable value. Components of accounts and other receivable, net of reserves, were as follows:

“Amounts billed, net” represents amounts invoiced to customers in accordance with our terms and conditions. These receivables are short term in nature and do not include any financing components.

“Unbilled receivables” consist of amounts where we satisfied our contractual obligations associated with customer inventory stocking agreements. Such amounts typically become billable upon the customer’s consumption of the inventory. We anticipate invoicing and collecting substantially all unbilled receivables within the next 12 months.

NOTE 14. RESTRUCTURING COSTS

In the fourth quarter of 2022, management approved a restructuring plan (the “2022 Plan”), which is expected to further improve our operating efficiencies and drive the realization of synergies from business combinations by consolidating our operations, optimizing our factory footprint including moving certain production into our higher volume factories, and reducing redundancies. We anticipate the 2022 Plan will be substantially completed, and associated expenses will be incurred by 2024.

​

In 2018, we committed to a restructuring plan (the “2018 Plan”) to optimize our manufacturing footprint and to improve our operating efficiencies and synergies related to business combinations. We incurred severance costs primarily related to the transition and exit of our facility in Shenzhen, China and actions associated with synergies related to the acquisition of Artesyn Embedded Technologies, Inc.’s embedded power business (“Artesyn”). This plan is substantially complete with the final closure of our Shenzhen facility expected in early 2023. The table below summarizes the charges related to our restructuring plans:

NOTE 17. 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 allowed 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 of Directors. For the year ended December 31, 2022 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. For the years ended December 31, 2021 and 2020 we based our profit-sharing contribution on matching 50% of employee contributions up to 6% of the employee’s compensation.

During the years ended December 31, 2022, 2021, and 2020 we recognized total defined contribution plan costs of $4.5 million, $3.1 million, and $2.6 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 diversified growth fund aims to generate an “equity-like” return over an economic cycle with significantly reduced volatility relative to equity markets and has the scope to use a diverse range of asset classes, including equities, bonds, cash, and alternatives (e.g., property, infrastructure, high yield bonds, floating rate debt, private, equity, hedge funds and currency). These investments are intended to provide a degree of protection against changes in the value of our plan’s liabilities related to changes in long-term expectations for interest rates and inflation.

Expected future payments during the next ten years for our defined benefit pension plans are as follows:

NOTE 18. STOCK-BASED COMPENSATION

The Board of Directors Compensation Committee administers our stock plans. As of December 31, 2022, we had two active stock-based incentive compensation plans: the 2017 Omnibus Incentive Plan (“the 2017 Plan”) and the ESPP. We issue all new equity compensation grants under these two plans; however, outstanding awards previously issued under inactive plans will continue to vest and remain exercisable in accordance with the terms of the respective plans.

On May 4, 2017, the stockholders approved the 2017 Plan, and all shares that were then available for issuance under the 2008 Omnibus Incentive Plan (“the 2008 Plan”) are now available for issuance under the 2017 Plan. The 2017 Plan and 2008 Plan provide for the grant of stock options, stock appreciation rights, restricted stock, stock units (including deferred stock units), unrestricted stock, and dividend equivalent rights. Any of the awards issued may be issued as performance-based awards to align stock compensation awards to the attainment of annual or long-term performance goals.

The following table summarizes information related to our stock-based incentive compensation plans:

​

​ | ​ | ​
​ | ​ | ​
​ | ​ | December 31, 2022
Shares available for future issuance under the 2017 Omnibus Incentive Plan | ​ | 1,475
Shares available for future issuance under the Employee Stock Purchase Plan | ​ | 619

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. Stock-based compensation was as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Years Ended December 31,
​ |  | 2022 |  | 2021 |  | 2020
Stock-based compensation expense | ​ | $ | 19,849 | ​ | $ | 15,739 | ​ | $ | 12,272

​

Estimated forfeiture rates for our stock-based compensation expense applicable to stock options and RSUs were approximately 9%, 8% and 5% for the years ended December 31, 2022, 2021 and 2020, respectively.

Restricted Stock Units

Generally, we grant 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.

Changes in our unvested RSUs were as follows:

​

​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended December 31, 2022
​ |  | ​ |  | Weighted-
​ | ​ | ​ | ​ | Average
​ | ​ | Number of | ​ | Grant Date
​ | ​ | RSUs | ​ | Fair Value
RSUs outstanding at beginning of period |  | 627 | ​ | $ | 76.37
RSUs granted |  | 593 | ​ | $ | 74.62
RSUs vested |  | (162) | ​ | $ | 83.16
RSUs forfeited |  | (255) | ​ | $ | 61.39
RSUs outstanding at end of period |  | 803 | ​ | $ | 78.46

​

The total intrinsic value of RSUs converted to shares for the years ended December 31, 2022, 2021 and 2020 was $13.6 million, $19.2 million, and $9.2 million, respectively. As of December 31, 2022, there was $35.3 million of total unrecognized compensation cost, net of expected forfeitures, related to non-vested RSUs, that we expect to recognize through December 2025, with a weighted-average remaining vesting period of 1.3 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.

The total intrinsic value of options exercised for the years ended December 31, 2022, 2021 and 2020 was $2.6 million, $2.6 million, and $1.9 million, respectively. Options outstanding on December 31, 2022 have aggregate intrinsic value of $4.6 million. As of December 31, 2022, there was $1.8 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 2.2 years.

Employee Stock Purchase Plan

The ESPP, a stockholder-approved plan, provides for the issuance of rights to purchase up to 1.5 million shares of common stock. Most employees are eligible to participate in the ESPP if employed for at least 20 hours per week during at least five months per calendar year. Participating employees 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, 2022, 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.

Estimating Fair Value

We estimated the fair value of each stock option and ESPP purchase right on the grant date using the Black-Scholes-Merton option pricing model with the following assumptions:

NOTE 19. 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 the 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.

NOTE 20. SIGNIFICANT CUSTOMER INFORMATION

During the year ended December 31, 2022, Applied Materials, Inc. and Lam Research Corporation accounted for 20% and 14%, respectively, of our total revenue compared to 20% and 10%, respectively, of our total revenue during the year ended December 31, 2021 and 18% and 10%, respectively, of our total revenue during the year ended December 31, 2020.

As of December 31, 2022 and 2021, the account receivable balance from Applied Materials, Inc. accounted for 18% of our total accounts receivable. No other customer’s account receivable exceeded 10% of our total accounts receivable in the periods presented.

​

NOTE 21. CREDIT FACILITY

In September 2019, in connection with the acquisition of Artesyn, we entered into a credit agreement (“Credit Agreement”) that provided aggregate financing of $500.0 million, consisting of a $350.0 million senior unsecured term loan facility (the “Term Loan Facility”) and a $150.0 million senior unsecured revolving facility (the “Revolving Facility” and together with the Term Loan Facility, the “Credit Facility”).

In September 2021, we amended the Credit Agreement whereby we borrowed an additional $85.0 million, which increased the aggregate amount outstanding under the Term Loan Facility to $400.0 million. In addition, we increased the Revolving Facility capacity by $50.0 million to $200.0 million. Both the Term Loan Facility and Revolving Facility mature on September 9, 2026.

The following table summarizes borrowings under our Credit Facility and the associated interest rate.

For more information on the interest rate swap that fixes the interest rate for a portion of our Term Loan Facility, see Note 8. Derivative Financial Instruments. The Term Loan Facility and Revolving Facility bear interest, at our option, at a rate based on a reserve adjusted “Eurodollar Rate” or “Base Rate,” as defined in the Credit Agreement, plus an applicable margin.

For all periods presented, we were in compliance with the Credit Agreement covenants. The following table summarizes our availability to withdraw on the Revolving Facility.

In addition to the available capacity on the Revolving Facility, prior to the maturity date of our Credit Agreement, we may also 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 at identical terms to our existing Credit Facility.

The fair value of the Term Loan Facility approximates the outstanding balance of $375.0 million as of December 31, 202 2.

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 Securities Exchange Act of 1934 (“Exchange Act”) is recorded, processed, summarized, and reported, within the time periods specified in the Securities and Exchange Commission’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 Oldham, 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, 2022. 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.

In April 2022, we acquired SL Power. Refer to Note 2. Acquisitions in Part II, Item 8 “Financial Statements and Supplementary Data” for additional information. SL Power’s objectives regarding internal controls over financial reporting are consistent, in all material respects, with Advanced Energy’s objectives. We are in the process of completing a more comprehensive review of SL Power’s internal control over financial reporting and will be implementing changes to better align their reporting and controls with the rest of Advanced Energy. As a result of the timing of the acquisition, anticipated changes, and general guidance issued by the SEC regarding exclusion of certain acquired businesses, we excluded SL Power from Advanced Energy’s December 31, 2022 assessment of internal controls over financial reporting. SL Power accounted for approximately 2% of our total assets at December 31, 2022, and 3% of our total net sales for the year ended December 31, 2022.

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, 2022, 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, 2022.

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, 2022.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during 2022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Controls and Procedures

Management has 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.
