The loss of Applied Materials, Inc. or Lam Research Corp. as a customer could have a material adverse effect on our results of operations. Backlog Our backlog was approximately $258.9 million at December 31, 2019, a 246.6% increase from $74.7 million at December 31, 2018. Backlog increased primarily due to the Artesyn acquisition, which added new backlog in the Data Center Computing and Telecom & Networking markets and incremental backlog in Industrial & Medical, as well as strengthening demand for semiconductor equipment late in the fiscal year. For more information related to our expectations for the markets we serve, see Business Environment and Trends in Item 7 "Management’s Discussion and Analysis of Financial Condition and Results of Operations." Backlog orders are firm orders scheduled to be filled and shipped in the next 12 months. Backlog orders are not necessarily an indicator of future sales levels because of variations in lead times and customer production demand pull systems, which are not reflected in orders or backlog. 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. Marketing, Sales and Distribution We sell our products through direct and indirect sales channels in North America, Europe and Asia. Our sales operations are primarily located in the United States, the PRC, the United Kingdom, Germany, Israel, Japan, South Korea, India, Singapore, Philippines, Hong Kong, Ireland and Taiwan. In addition to a direct sales force, we have independent sales representatives, channel partners and distributors that support our selling efforts. We maintain customer service offices at many of the locations listed above, as well as other sites near our customers’ locations. We believe that customer service and technical support are important competitive factors and are essential to building and maintaining close, long-term relationships with our customers. 9 The following table presents our sales by geographic region for the years ended December 31, 2019, 2018, and 2017.

See Item 1A "Risk Factors" for a discussion of certain risks related to our foreign operations. Manufacturing The manufacturing of our products is primarily performed in major sites in the PRC and the Philippines. We have begun pilot production and expect to open an additional major manufacturing site in Penang, Malaysia in 2020. In addition, we perform limited specialty manufacturing for some of our products in the United States of America, United Kingdom, Germany and Denmark. Manufacturing in these locations, primarily the PRC, exposes us to risks, such as exchange controls and currency restrictions, changes in local economic conditions, changes in laws and regulations, government actions, political conditions, and other regional risks including natural disasters and health risks, and an inability to meet customer demands if one of our facilities becomes impaired. 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. We seek to reduce costs and to lower the risks of production and service interruptions, as well as shortages of key parts by: • selecting and qualifying alternate suppliers 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 product at 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; • 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 on a timely basis and in geographies that reduce costs without degradation in quality; locating certain manufacturing operations in areas that are closer to suppliers and customers; and competitively sourcing parts through electronic bidding tools to ensure the lowest total cost is achieved for the parts needed in our products. 10 Intellectual Property We seek patent protection for inventions governing new products or technologies as part of our ongoing research and development. We currently hold 273 United States patents and 341 foreign issued patents, and have 119 patent applications pending in the United States, 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. Litigation may, from time to time, be necessary to enforce patents issued to us, to protect trade secrets or know- how owned by us, to defend us against claimed infringement of the rights of others, or to determine the scope and validity of the proprietary rights of others. See "We are highly dependent on our intellectual property" in Item 1A "Risk Factors." Competition The markets we serve are highly competitive and characterized by rapid technological development and changing customer requirements. We face a wide variety of competitors and no single company dominates any of our markets. Significant competitive factors in our markets include product performance, compatibility with adjacent products, price, quality, reliability, and level of customer service and support. We encounter substantial competition from foreign and domestic companies for each of our product lines. Our list of competitors has increased over the past year due to the acquisition of Artesyn’s Embedded Power business, which competes in different markets and against different competitors. Some of our competitors have greater financial and other resources than we do. In some cases, competitors are smaller than we are, but are well established in specific product niches. Adtec Plasma Tech. Co., Ltd., COMET Holding AG., Daihen Corp., Kyosan Electric Mfg. Co., Ltd., MKS Instruments, Inc., New Power Plasma Co., Ltd. and TRUMPF Hüttinger GmbH + Co. KG. are primary competitors to our power conversion products for semiconductor and thin film processing. Competitors to our low voltage AC-DC and DC-DC embedded power conversion offerings include, but are not limited to ABB Ltd., Acbel Polytech Inc., Cosel Co., Ltd., Delta Electronics, Inc., Flex Ltd., Lite-On Technology Corp., Murata Manufacturing, MEAN WELL Enterprises, TDK-Lambda Americas Inc. and XP Power Ltd. In high voltage DC-DC, our competitors include, but are not limited to Crane Co., Matsusada Precision, Inc., and Spellman High Voltage Electronics Corp. CD Automation, Control Concepts Inc., Eurotherm and Spang Power Electronics offer products that compete with our power control modules. BASF SE., Fluke Corp., LayTec AG. and Photon Control Inc. offer products that compete with our thermal measurement and instrumentation products. Honeywell International, Inc., Morgan Schaffer Ltd., Qualitrol Corp. and Williamson Corp. offer products that compete with our gas detection and monitoring products. In addition, a focus on local content is causing new competitors to emerge around the world, with strong support from local governments, industry leaders, and investors. Our ability to continue to compete successfully in these markets depends on our ability to make timely introduction of new products and enhancements to existing products, to localize these development and production activities in key world regions close to our customers, and to produce high quality products. We expect our competitors will continue to improve the design and performance of their products and introduce new products with competitive performance characteristics. We believe that we compete effectively with respect to these factors, although we cannot assure that we will be able to compete effectively in the future. Research and Development The market for our products is characterized by ongoing technological changes and evolving customer requirements. We believe that continued and timely development of new highly-differentiated products and enhancements to existing products to support end user and OEM requirements is necessary for us to maintain a competitive position in the markets we serve. Accordingly, we continue to devote a significant portion of our personnel and financial resources to research and development projects and seek to maintain close relationships with our key customers and other industry leaders in order to remain responsive to their product requirements now and in the future. 11 Research and development expenses were $101.5 million in 2019, $76.0 million in 2018, and $58.0 million in 2017, representing 12.9% of our sales in 2019, 10.6% of our sales in 2018, and 8.6% of our sales in 2017. Employees As of December 31, 2019, we had a total of 10,917 employees. Our employees are not represented by unions, except for statutory organization rights applicable to our employees in the PRC and Germany. We believe that our continued success depends, in part, on our ability to attract and retain qualified personnel. We consider our relations with our employees to be good. Environmental Matters We are subject to federal, state, and local environmental laws and regulations, as well as the environmental laws and regulations of the foreign federal and local jurisdictions in which we have manufacturing and service facilities. We believe we are in material compliance with all such laws and regulations. Compliance with federal, state, and local laws and regulations has not had, and is not expected to have, an adverse effect on our capital expenditures, competitive position, financial condition, or results of operations. Available Information Our website address is www.advancedenergy.com. We make available, free of charge on our website, our Annual Report on Form 10 - K, quarterly reports on Form 10 - Q, current reports on Form 8 - K, and all amendments to these reports as soon as reasonably practicable after filing such reports with, or furnishing them to, the Securities and Exchange Commission (“SEC”). Such reports are also available at www.sec.gov. Information contained on our website is not incorporated by reference in, or otherwise part of, this Annual Report on Form 10 - K nor any of our other filings with the SEC. 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 significant based on information that is currently available. These risks and uncertainties have the potential to materially affect our business, financial condition, results of operations, cash flows and future results. Such risks and uncertainties may also impact the accuracy of forward-looking statements included in this Form 10 - K and other reports we file with the SEC. COVID-19 (“Coronavirus”) and the Impact on our Business As we have grown our locations worldwide, our risk to regional and worldwide viruses and diseases has also grown. For example, the continuing spread in early 2020 of the Coronavirus and related government actions may adversely affect our manufacturing locations in China and worldwide. If the Coronavirus continues on its current path, we may see adverse impact on 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. Further, we may experience adverse impact with our global supply chain partners and transportation service providers. Our customers may also delay orders should our products be included as a subsystem into their systems. The Coronavirus could adversely impact our near- term and long-term revenues, earnings and cash flow and will require expenditures in the short-term to address the current situation in Asia. This situation is developing rapidly, and other impacts may arise that we are not aware of currently. We have created a rapid response team to mitigate risks we are aware of and as they arise. 12 The industries in which we compete are subject to volatile and unpredictable cycles. As a supplier to the global semiconductor equipment, telecom & networking, data center computing and industrial & medical industries, we are subject to business cycles, the timing, length, and volatility of which can be difficult to predict. Certain of these industries historically have been cyclical due to sudden changes in customers’ manufacturing capacity requirements and spending, which depend in part on capacity utilization, demand for customers’ products, inventory levels relative to demand, and access to affordable capital. These changes have affected the timing and amounts of customers’ purchases and investments in technology, and continue to affect our orders, net sales, operating expenses, and net income. In addition, we may not be able to respond adequately or quickly to the declines in demand by reducing our costs. We may be required to record significant reserves for excess and obsolete inventory as demand for our products changes. 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 a sufficient number of qualified individuals. If we are not able to timely and appropriately adapt to changes in our business environment or to accurately assess where we are positioned within a business cycle, our business, financial condition, or results of operations may be materially and adversely affected. For example, following record levels of demand in the first half of 2018, the semiconductor equipment market experienced a decline, and, as a result, Advanced Energy’s revenue from the semiconductor equipment market declined 24.5% during 2019, as compared to 2018. Although the semiconductor equipment market improved during the fourth quarter of 2019, it is unclear at this time if the market will recover to previous levels. In addition, the market may be characterized in the future with more “mini-ramps” rather than sustained growth periods as experienced during 2015-2017. In addition, our Data Center Computing and Telecom Networking markets are characterized by large program investments, which can cause variations in quarterly or annual revenues. Deterioration of economic conditions could negatively impact our business. Our business may be adversely affected by changes in national or global economic conditions, including inflation, interest rates, availability of capital markets, consumer spending rates, energy availability and costs (including fuel surcharges) and the effects of government initiatives to manage economic conditions. Any such changes could adversely affect the demand for our products both in domestic and export markets, or the cost and availability of our needed raw materials and packaging materials, thereby negatively affecting our financial results. A disruption in credit and other financial markets and deterioration of national and global economic conditions, could, among other things: • negatively impact global demand for our products, which could result in a reduction of sales, operating income and cash flows; • make it more difficult or costly for us to obtain financing for our operations or investments or to refinance our debt in the future; cause our lenders to depart from prior credit industry practice and make more difficult or expensive the granting of any technical or other waivers under our debt agreements to the extent we may seek them in the future; decrease the value of our investments; and impair the financial viability of our insurers. • • Our long-term success and results of operations depend on our ability to successfully integrate Artesyn’s business and operations and realize the anticipated benefits from the acquisition. In September 2019, we acquired Artesyn Embedded Technologies, Inc.’s (“Artesyn”) Embedded Power business, and we are currently in the early stages of combining Artesyn’s Embedded Power business with our business. The acquisition of Artesyn’s Embedded Power business has significantly increased our embedded power product offerings, increased our exposure to the industrial and medical, datacenter computing, and telecom networking end markets, and significantly increased the number of employees and facilities. We believe there is minimal product overlap 13 between Artesyn’s Embedded Power business and our other acquisitions, including the acquisition of Excelsys Technologies in 2017. To realize the anticipated benefits of the acquisition, we must successfully combine our businesses in an efficient and effective manner and realize our synergy and cost-savings targets. Integrating Artesyn’s Embedded Power business and operations with ours will require significant management attention, efforts and expenditures, and we may not be able to achieve the integration in an effective, complete, timely or cost-efficient manner. Potential risks related to our acquisition of Artesyn’s Embedded Power business include our ability to: • maintain and improve Artesyn’s financial and operating results while integrating and optimizing our • • • • • • • • • • • • • combined sales, marketing, manufacturing and corporate administrative organizations; avoid lost revenue due to customer confusion, alienation or misinformation regarding the transaction, and retain and expand Artesyn’s customer base with aligning our sales efforts; avoid lost revenue resulting from the distraction or confusion of our personnel as a consequence of the acquisition and ongoing integration efforts; optimize our combined worldwide manufacturing footprint while utilizing Artesyn’s vertically integrated manufacturing model for a broader set of company products; realize expected synergies and cost savings across the organization while managing our existing businesses, contracts and relationships; successfully eliminate fixed costs previously absorbed by other businesses prior to the transaction; recognize and capitalize on anticipated product sales and technology enhancement opportunities presented by our combined businesses; expand our financial and management controls and reporting systems and procedures to integrate and manage Artesyn; integrate our information technology systems to mitigate cyber-security risks and enable the management and operation of the combined business; effectively manage risks related to Artesyn’s foreign operations, including foreign currency risk, geographic risks, and local employee related risks; integrate Artesyn into our global tax structure and manage the related impact on our current and future tax rates as a result of the acquisition; identify and retain key Artesyn personnel and transition their critical knowledge; adequately familiarize us with Artesyn’s products and technology and certain of its markets and customer base such that we can manage Artesyn’s business effectively; successfully integrate our respective corporate cultures such that we achieve the benefits of acting as a unified company; and • meet target deadlines in achieving regulatory compliance. Other potential risks related to our acquisition of Artesyn’s Embedded Power business include: • • the assumption of unknown or contingent liabilities, or other unanticipated events or circumstances; and the potential to incur or record significant cash or non-cash charges or write down the carrying value of intangible assets and goodwill obtained in the Artesyn acquisition, which could adversely impact our cash flow or lower our earnings in the period or periods for which we incur such charges or write down such assets. If we are unable to successfully or timely integrate the operations of Artesyn’s Embedded Power business into our business, we may be unable to realize the revenue growth, synergies, cost-savings and other anticipated benefits resulting from the acquisition and our business could be adversely affected. Additionally, we have incurred and will continue to incur transaction-related costs, including legal, regulatory and other costs associated with implementing integration plans, including facilities and systems consolidation costs and employment-related costs. Although we expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow us to offset transaction and integration-related costs over time, this net benefit may not be achieved in the near term, or at all. Further, we may not realize the expected benefits from the acquisition. Artesyn’s 14 Embedded Power business and operations may not achieve the anticipated revenues and operating results. Any of the foregoing risks could materially harm our business, financial condition and results of operations. 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. As of December 31, 2019, our total debt was $341.3 million, excluding unamortized debt issuance costs, of which $17.5 million was classified as current. We are contractually obligated to make quarterly payments of $4.4 million, plus accrued interest, with any outstanding balance due in September 2024. 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 indebtedness. 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 restrictions 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; • 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 of our assets; and create liens on our assets to secure debt. • Our debt obligations contain certain customary events of default. Any breach of the covenants or other event of default could cause a default on our debt obligations, which could restrict our ability to borrow under our revolving credit facility. If there were an event of default under certain provisions of our debt arrangements that was not cured or waived, the holders of the defaulted debt may be able to cause all amounts outstanding with respect to the debt instrument, plus any required settlement costs, to be due and payable immediately. 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 such outstanding debt instruments or applicable laws or equity. Any of these events could have a material adverse effect on our business, financial condition, results of operations, and cash flows. Significant developments stemming from recent U.S. government actions and proposals concerning tariffs and other economic proposals could have a material adverse effect on us. Recent U.S. government actions are imposing greater restrictions and economic disincentives on international trade impacting imports and exports. The U.S. government has adopted changes, and intends to adopt further changes, to trade policy and in some cases, to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements. It has initiated the imposition of additional tariffs on certain foreign goods, including steel and aluminum, semiconductor manufacturing equipment and spare parts thereof. Additionally, the government may also propose export rule changes that lower the percentage of permissible U.S. content for certain non-U.S. manufactured goods being sold to companies on the U.S. Entity List, further restrict the sale of foreign-made goods that are based on U.S. technology, and regulate the use of any U.S. origin content in certain manufacturing equipment used to produce goods for certain companies. 15 Examples of recent actions are tariffs on steel and aluminum product imports announced by the U.S. Department of Commerce in March 2018, the scope of which increased on Feb. 8, 2020, and a 25% tariff on certain products that originate in China announced by the United States Trade Representative (“USTR”) in June 2018. The USTR also announced in June and July 2018 two additional supplemental lists of products that are subject to tariffs if the goods imported into the United States originate in China, which would increase the cost of imported products. These supplemental lists issued by the USTR added an additional 25% on certain semiconductor equipment and parts originating in China that are sold by us or used in our business in the United States. In August 2018, the second list was made effective with a 25% tariff and in September 2018 the third list was made effective with a 10% tariff, increasing to 25% in May 2019. A fourth list was proposed by USTR in May 2019 for all remaining items originating in China. A portion of the fourth list (“4a”), was made effective September 1, 2019, with an additional tariff of 15%, reduced to 7.5% on February 14, 2020. The remainder of the fourth list (“4b”) was scheduled to have an additional tariff of 15% go into effect on December 15, 2019, however on December 13, 2019, the tariffs for list 4b were suspended after the U.S. announced it would enter into a trade agreement with China (the “Phase 1 Agreement”). The Phase 1 Agreement is expected to have no impact on the tariffs imposed on Company products. Any increase in the cost of importing such goods and parts could decrease our margins, reduce the competitiveness of our products, or inhibit our ability to sell products or purchase necessary parts, which could have a material adverse effect on our business results, results of operations, or financial condition. The U.S. Department of Commerce is currently considering proposed rules that decrease the amount of U.S. origin content allowed for non-U.S. manufactured products that are sold to companies on the U.S. Entity List, expand the restrictions on the sale of foreign-made goods that are based on U.S. technology or software, and regulate the use of U.S. origin semiconductor manufacturing equipment that produces semiconductor devices for certain companies. At this time, the potential rule changes are not anticipated to impact the Company’s sales of non-U.S. products; however, the developments in this area are fast-moving and any unpredicted rule changes could adversely affect our business results, operations or financial condition. 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. We cannot predict future trade policy, the terms of any renegotiated trade agreements or additional imposed tariffs and their impact on our business. The adoption and expansion of trade restrictions, the occurrence of a trade war, or other governmental action related to tariffs or trade agreements or policies has the potential to 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. Our operations in the People’s Republic of 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 outside the United States are located in the PRC, 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 PRC laws and regulations, possible expropriation or other 16 PRC government actions, and unsettled political conditions including potential changes in U.S. policy regarding overseas manufacturing. In addition, Artesyn added a significant additional footprint in both facilities and resources in the PRC. These factors may have a material adverse effect on our operations, business, results of operations, and financial condition. See "We are exposed to risks associated with worldwide financial markets and the global economy" risk factor below. The PRC’s economy differs from the economies of most developed countries in many respects, including with respect to the amount of government involvement, level of development, rate of growth, control of foreign exchange and allocation of resources. While the economy of the PRC has experienced significant growth in the past 20 years, growth has been uneven across different regions and amongst various economic sectors of the PRC. The PRC government has implemented various measures to encourage economic development and guide the allocation of resources. Strikes by workers and picketing in front of the factory gates of certain companies in Shenzhen have caused unrest among some workers seeking higher wages, which could impact our manufacturing facility in Shenzhen. While some of the government’s measures may benefit the overall economy of the PRC, they may have a negative effect on us. For example, our financial condition and results of operations may be materially and adversely affected by government control over capital investments or changes in tax regulations that are applicable to us as well as work stoppages. We are subject to risks inherent in international operations. Sales to our customers outside the United States were approximately 59.2% and 48.4% of our total sales for the year ended December 31, 2019 and 2018, respectively. The international acquisitions have increased our 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; 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 intellectual property and contract rights; trade restrictions, political instability, disruptions in financial markets, and deterioration of economic conditions; customs regulations and the import and export of goods (including customs audits in various countries that occur from time to time); the ability to provide enough levels of technical support in different locations; our ability to obtain business licenses that may be needed in international locations to support expanded operations; timely collecting accounts receivable from foreign customers including significant balances in accounts receivable from foreign customers as of December 31, 2019; collection of accounts receivable from foreign customers can also be unexpectedly delayed beyond our payment terms if the project itself is delayed and/or government funded. For example, tariffs and slower growth have impacted certain of our Chinese markets which have delayed projects. If these projects are permanently delayed or cancelled it could have a negative impact on our financial results or projections; changes in tariffs, taxes, and foreign currency exchange rates; and recent protests and rioting in Hong Kong have affected travel in the region and may result in governmental actions that could impact business in the region. Our profitability and ability to implement our business strategies, maintain market share and compete successfully in international markets will be compromised if we are unable to manage these and other international risks successfully. 17 Our product lines are manufactured only at a few sites and our sites are not generally interchangeable. Our power products for the semiconductor industry are manufactured in Shenzhen, PRC. Our high voltage products are manufactured in Ronkonkoma and Lockport, New York, Littlehampton, United Kingdom and Shenzhen, PRC. Our thermal instrumentation products are manufactured in Vancouver, Washington, Santa Clara, California, Littlehampton, United Kingdom and Frankfurt, Germany. Our pyrometry solutions are manufactured in Ballerup, Denmark and Santa Clara, California. Our Telecom & Networking and Data Center Computing products are manufactured in Zhongshan, PRC, Rosario, Philippines and Santa Rosa, Philippines. Some of Artesyn’s Embedded Power business’ products will be contract manufactured by the carved-out former Artesyn consumer group at their Luoding, China facility until September 2020. Each facility is under operating lease 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. Each facility manufactures different products, and therefore, is not interchangeable. Natural, uncontrollable occurrences or other operational issues at any of our manufacturing facilities could significantly reduce our productivity at such site and could prevent us from meeting our customers’ requirements in a timely manner, or at all. For example, recent concerns regarding the spread of the Coronavirus and related government actions may result in temporary shut-down of our facilities and impact availability of materials supply and manufacturing employees, particularly in our China operations. Any potential losses from such occurrences could significantly affect our relationship with customers, operations and results of operations for a prolonged period. As a result, we are investing in additional production options in Malaysia. We believe this investment will help to mitigate our exposure to regional risks, improve our business continuity profile and lower costs over time. Our restructuring and other cost reduction efforts have included transitioning manufacturing operations to our facility in Shenzhen from other manufacturing facilities, such as Fort Collins, Colorado and Littlehampton, United Kingdom, which renders us increasingly reliant upon our Shenzhen facility. We have been notified that we will be required to relocate our Shenzhen, PRC manufacturing facility by December 2021. A disruption in manufacturing at our Shenzhen facility, from whatever cause, could have a significantly adverse effect on our ability to fulfill customer orders, our ability to maintain customer relationships, our costs to manufacture our products and, as a result, our results of operations and financial condition. To mitigate these risks, we are investing in a dual manufacturing facility in Penang, Malaysia that will be capable of manufacturing our semiconductor and other products. We have begun pilot production for qualification and expect to open the facility in 2020. Our evolving manufacturing footprint may increase our risk. The nature of our manufacturing is evolving as we continue to grow by acquisition. Historically, our principal manufacturing location has been in Shenzhen, PRC; however, we have also added specialized manufacturing at our Littlehampton, United Kingdom, Ballerup, Denmark, Frankfurt, Germany, Ronkonkoma and Lockport, New York and Santa Clara, California facilities. From time to time we may be required to or we may choose to relocate manufacturing or migrate manufacturing of specific products between facilities or to third party manufacturers as part of our cost consolidation efforts. A disruption in supply because of these manufacturing relocations could have a significantly adverse effect on our ability to fulfill customer orders. We have been notified that we will be required to relocate our Shenzhen, PRC manufacturing facility by December 2021. If we do not successfully coordinate the timely manufacturing and distribution of our products during this time, we may have insufficient supply of products to meet customer demand, we could lose sales, we may experience a build-up in inventory, or we may incur additional costs. In addition, we are investing in a second factory in Malaysia to help mitigate business continuity, geopolitical and other risks. If we do not successfully implement this factory it could result in increased expenses and disruption of supply to our customers during the transition period. In addition, the acquisition of Artesyn’s Embedded Power business added significant vertically integrated manufacturing sites in China and the Philippines. These sites represent large fixed costs which are difficult to flex as economic and other conditions change. If we do not successfully integrate these operations and operate them in an efficient manner, we could experience greater losses in times of revenue reduction. 18 With the acquisition of Artesyn, our strategy is to optimize and reduce our manufacturing footprint over the next several years primarily in China and the Philippines. Our strategy will require the expenditure on facilities, employee severance and other related operations. If we are not successful in this strategy, we may impact our manufacturing capability and not reduce long-term costs as we had planned. Raw material, part, component, and subassembly shortages, exacerbated by our dependence on sole and limited source suppliers, could affect our ability to manufacture products and systems and could delay our shipments. Our business depends on our ability to manufacture products that meet the rapidly changing demands of our customers. Our ability to timely manufacture our products depends in part on the timely delivery of raw materials, parts, components, and subassemblies from suppliers. We rely on sole and limited source suppliers for some of our raw materials, parts, components, and subassemblies that are critical to the manufacturing of our products. This reliance involves several risks, including the following: • • • • • • • • • the inability to obtain an adequate supply of required parts, components, or subassemblies; supply shortages, if a sole or limited source provider ceases operation; the need to fund the operating losses of a sole or limited source provider; reduced control over pricing and timing of delivery of raw materials and parts, components, or subassemblies; the need to qualify alternative suppliers; suppliers that may provide parts, components or subassemblies that are defective, contain counterfeit goods or are otherwise misrepresented to us in terms of form, fit or function; the inability of our suppliers to develop technologically advanced products to support our growth and development of new products; the impact of geopolitical issues or tariffs that could affect the cost and availability of required parts, components, or subassemblies; and the impact of regional or global health issues and related actions could affect the availability of required parts, components, or subassemblies. From time to time, our sole or limited source suppliers have given us notice that they are ending supply of critical parts, components, and subassemblies that are required for us to deliver product. If we cannot qualify alternative suppliers before ending supply of critical parts from the sole or limited source suppliers, we may be required to make a last-time-buy(s) and take possession of material amounts of inventory in advance of customer demand. In some instances, the last-time-buy materials required to be purchased may be for several years which in turn exposes us to additional excess and obsolescence risk. If we cannot qualify alternative suppliers before the last-time-buy materials are utilized in our products or legacy inverter warranty operations, we may be unable to deliver further product or legacy inverter warranty service to our customers. Qualifying alternative suppliers could be time consuming and lead to delays in, or prevention of delivery of products to our customers, as well as increased costs. If we are unable to qualify additional suppliers and manage relationships with our existing and future suppliers successfully, if our suppliers experience financial difficulties including bankruptcy, or if our suppliers cannot meet our performance or quality specifications or timing requirements, we may experience shortages, delays, or increased costs of raw materials, parts, components, or subassemblies. This in turn could limit or prevent our ability to manufacture and ship our products, which could materially and adversely affect our relationships with our current and prospective customers and our business, financial condition, and results of operations. Our orders of raw materials, parts, components, and subassemblies are based on demand forecasts. 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. Orders with our 19 suppliers cannot always be amended in response. In addition, in order 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 amount 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, in order to fulfill just in time orders, regardless of whether the customers expect to place such orders. We currently have firm purchase commitments and agreements with various suppliers to ensure the availability of components. If demand for our products does not continue at current levels, we might not be able to use all of the components that we are required to purchase under these commitments and agreements, and our reserves for excess and obsolete inventory may increase, which could have a material adverse effect on our results of operations. If demand for our products exceeds our customers’ and our forecasts, we may not be able to timely obtain enough raw materials, parts, components, or subassemblies, on favorable terms or at all, to fulfill the excess demand. Increased governmental action on income tax regulations could negatively 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. Such an increase in audit activity could have a negative impact on companies which operate internationally, as we do. Activities necessary to integrate acquisitions may result in costs in excess of current expectations or be less successful than anticipated. We have completed acquisitions in the past and we may acquire other businesses in the future. The success of such transactions will depend on, among other things, our ability to integrate assets and personnel acquired in these transactions and to apply our internal controls process to these acquired businesses. The integration of acquisitions may require significant attention from our management, and the diversion of management’s attention and resources could have a material adverse effect on our ability to manage our business. Furthermore, we may not realize the degree or timing of benefits we anticipated when we first entered into the acquisition transaction. If actual integration costs are higher than amounts originally anticipated, if we are unable to integrate the assets and personnel acquired in an acquisition as anticipated, or if we are unable to fully benefit from anticipated synergies, our business, financial condition, results of operations, and cash flows could be materially adversely affected. Additionally, our efforts to optimize our manufacturing footprint through consolidation and relocation resulting from acquisitions may result in a disruption in our ability to supply our customers which could adversely affect our operations. We have historically made acquisitions and divestitures. However, we may not find suitable acquisition candidates in the future and we may not be able to successfully integrate and manage acquired businesses. In either an acquisition or a divestiture, we may be required to make fundamental changes in our ERP, business processes and tools which could disrupt our core business and harm our financial condition. In the past, we have made strategic acquisitions of other corporations and entities, as well as asset purchases, and we continue to evaluate potential strategic acquisitions of complementary companies, products, and technologies. We have also divested businesses. In the future, we could: • • • • • issue stock that would dilute our current stockholders’ percentage ownership; pay cash that would decrease our working capital; incur debt; assume liabilities; or incur expenses related to impairment of goodwill and amortization. Acquisitions and divestitures also involve numerous risks, including: • • problems combining or separating the acquired/divested operations, systems, technologies, or products; an inability to realize expected sales forecasts, operating efficiencies or product integration benefits; 20 • • • • • • • • difficulties in coordinating and integrating geographically separated personnel, organizations, systems, and facilities; difficulties integrating business cultures; unanticipated costs or liabilities; diversion of management’s attention from our core business; adverse effects on existing business relationships with suppliers and customers; potential loss of key employees, particularly those of purchased organizations; incurring unforeseen obligations or liabilities in connection with either acquisitions or divestitures; and the failure to complete acquisitions even after signing definitive agreements which, among other things, would result in the expensing of potentially significant professional fees and other charges in the period in which the acquisition or negotiations are terminated. We may not be able to successfully identify appropriate acquisition candidates, to integrate any businesses, products, technologies, or personnel that we might acquire in the future or achieve the anticipated benefits of such transactions, which may harm our business. We may be unable to realize expected benefits from our cost reduction and restructuring efforts In order to operate more efficiently and control costs, we announce from time to time restructuring plans, which include workforce reductions, global facility optimizations or consolidations and other cost reduction initiatives. These plans are intended to generate operating expense savings through reductions in direct and indirect expenses as well as improved efficiencies. These types of cost reduction and restructuring activities are complex. If we do not successfully manage our current restructuring activities, or any future restructuring activities, expected efficiencies and benefits might be delayed or not realized, and our operations and business could be disrupted. 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 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. 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. The acquisition of Artesyn may change our mix of earnings in various tax jurisdictions and may impact our overall current or future tax rate. 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 foreign-derived intangible income (FDII), global intangible low-tax income (GILTI) and base erosion and anti-abuse tax laws (BEAT); 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 21 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, as a result 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 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. We are exposed to risks associated with worldwide financial markets and the global economy. Our business depends on the expansion of manufacturing capacity in our end markets and the installation base for the products we sell. In the past, severe tightening of credit markets, turmoil in the financial markets, and a weakening global economy have contributed to slowdowns in the industries in which we operate. Some of our key markets depend largely on consumer spending. Economic uncertainty, such as that recently experienced in the PRC, exacerbates negative trends in consumer spending and may cause our customers to push out, cancel, or refrain from placing orders. Difficulties in obtaining capital and uncertain market conditions may also lead to a reduction of our 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 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. As discussed in "Our orders of raw materials, parts, components, and subassemblies are based on demand forecasts," a significant percentage of our expenses are relatively fixed and based, in part, on expectations of future net sales. If a sudden decrease in demand for our products from one or more customers were to occur, the inability to adjust spending quickly enough to compensate for any shortfall would magnify the adverse impact of a shortfall in net sales on our results of operations. Conversely, if market conditions were to unexpectedly improve and demand for our products were to increase suddenly, we might not be able to respond quickly enough, which could have a negative impact on our results of operations and customer relations. Our results of operations could be affected by natural disasters and other events in the locations in which we or our customers or suppliers operate. We have manufacturing and other operations in locations subject to natural occurrences such as severe weather and geological events including earthquakes or tsunamis that could disrupt operations. In addition, our suppliers and customers also have operations in such locations. A natural disaster, fire, explosion, public health issue (for example, an outbreak of a pandemic disease such as Coronavirus, avian influenza, measles or Ebola) 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. We transitioned a significant amount of our supply base to Asian suppliers. We transitioned the purchasing of a substantial portion of components for our products to Asian suppliers to lower our materials costs and shipping expenses. These components might require us to incur higher than anticipated testing or repair costs, which would have an adverse effect on our operating results. Customers who have strict and extensive qualification requirements might not accept our products if these lower-cost components do not meet their requirements. A delay or refusal by our customers to accept such products, as well as an inability of our suppliers to meet our purchasing requirements, might require us to purchase higher-priced components from our existing suppliers or might cause us to lose sales to these customers, either of which could lead to decreased revenue and gross margins and have an adverse effect on our results of operations. 22 We must continually design and introduce new products into the markets we serve to respond to competition and rapid technological changes. We operate in a highly competitive environment where innovation is critical, our future success depends on many factors, including the effective commercialization and customer acceptance of our products and services. The development, introduction and support of a broadening set of products is critical to our continued success. Our results of operations could be adversely affected if we do not continue to develop new products (including software and firmware capabilities), improve and develop new applications for existing products, and differentiate our products from those of competitors resulting in their adoption by customers. 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 customers demand the markets we serve are constantly changing in terms of advancement in applications, core technology and competitive pressures. New products we design for capital equipment manufacturers typically have a lifespan of five to ten years. 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, and we may win or lose new design wins for our existing customers or new customers next generations of equipment. In case existing or new customers do not choose our products as a result of the development, evaluation and qualification efforts related to the design win process, our market share will be reduced, the potential revenues related to the lifespan of our customers’ products, which can be five to ten years, will not be realized, and our business, financial condition and results of operations would be materially and adversely impacted. We generally have no long-term contracts with our customers requiring them to purchase any specified quantities from us. 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. If we are unable to adjust our business strategy successfully for some of our product lines to reflect the increasing price sensitivity on the part of our customers, 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. As a result of recent economic conditions and changes in various markets that we serve, our customers have experienced significant cost pressures. We have observed increased price sensitivity on the part of our customers. If competition against any of our product lines should come to focus solely on price rather than on product performance and technology innovation, we will need to adjust our business strategy and product offerings accordingly, and if we are unable to do so, our business, financial condition, and results of operations could be materially and adversely affected. Our competitive position could be weakened if we are unable to convince end users to specify that our products be used in the equipment sold by our customers. The end users in our markets may direct equipment manufacturers to use a specified supplier’s product in their equipment at a particular facility. This occurs with frequency because our products are critical in manufacturing process control for thin-film applications. Our success, therefore, depends in part on our ability to have end users specify that our products be used at their facilities. In addition, we may encounter difficulties in changing established relationships of competitors that already have a large installed base of products within such facilities. 23 The markets we operate in are highly competitive. We face substantial competition, primarily from established companies, some of which have greater financial, marketing, and technical resources than we do. We expect our competitors will continue to develop new products in direct competition with ours, improve the design and performance of their products, and introduce new products with enhanced performance characteristics including software and firmware capabilities. In order to remain competitive, we must improve and expand our products and product offerings. In addition, we may need to maintain a high level of investment in research and development and expand our sales and marketing efforts, particularly outside of the United States. We might not be able to make the technological advances and investments necessary to remain competitive. If we were unable to improve and expand our products and product offerings, our business, financial condition, and results of operations could be materially and adversely affected. A significant portion of our sales and accounts receivable are concentrated among a few customers. Our ten largest customers accounted for 57.3%, 62.5% and 70.4% of our sales for the year ended December 31, 2019, 2018 and 2017, respectively. During the year ended December 31, 2019, sales to Applied Materials, Inc. and Lam Research were $164.7 million and $88.3 million, respectively. During the year ended December 31, 2018 sales to Applied Materials, Inc., and Lam Research were $258.0 million and $109.0 million, respectively. During the year ended December 31, 2017, sales to Applied Materials, Inc., and Lam Research were $224.8 million and $155.3 million, respectively. A new customer, Nidec Motor Corporation, acquired in connection with the acquisition of Artesyn’s Embedded Power business, had a $38.1 million accounts receivable balance as of December 31, 2019. Applied Material, Inc. had a $36.8 million and $34.3 million accounts receivable balance as of December 31, 2019 and December 31, 2018, respectively. In addition, the Company has several large customers in China dependent on the Chinese government for project funding. A significant decline in sales from these or other large customers, or the Company’s inability to collect on these sales, could materially and adversely impact our business, results of operations and financial condition. We maintain significant amounts of cash in international locations. 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 negatively affected by liquidity, credit deterioration, financial results, economic risk, political risk, sovereign risk or other factors. The Company intends to utilize its foreign cash to expand our international operations through internal growth and strategic acquisitions. If our intent changes or if these funds are needed for our U.S. operations, or we are negatively impacted by any of the factors above, our financial condition and results of operations could be materially adversely affected. Globalization of sales increases risk of compliance with policy. We operate in an increasingly complex sales environment around the world which places greater importance on our global control environment and imposes additional oversight risk. Such increased complexity could adversely affect our operating results by increasing compliance costs in the near-term and by increasing the risk of control failures in the event of non-compliance. Market pressures and increased low-cost competition may reduce or eliminate our profitability. Our customers continually exert pressure on us to reduce our prices and extend payment terms. Given the nature of our customer base and the highly competitive markets in which we compete, we may be required to reduce our prices or extend payment terms to remain competitive. We have recently seen pricing pressure from our largest customers due in part to low-cost competition and market consolidation. As a result of the competitive markets we serve, from time to time we may enter into long term pricing agreements with our largest customers that results in reduced product pricing. Such reduced product pricing may result in product margin declines unless we are successful in reducing our product costs ahead of such price reductions. In addition, our newly acquired business competes in markets that are more price competitive which may include dual or multi sourcing. We believe some of our Asian competitors benefit from local governmental funding incentives and purchasing preferences from end-user customers in their 24 respective countries. Moreover, in order to be successful in the current competitive environment, we are required to accelerate our investment in research & development to meet time-to-market, performance and technology adoption cycle needs of our customers simply in order to compete for design wins, and if successful, receive potential purchase orders. Given such up-front investments we must make and the competitive nature of our markets, we may not be able to reduce our expenses in an amount enough to offset potential margin declines or loss of business and may not be able to meet customer product time-line expectations. The potential decrease in cash flow could materially and adversely impact our financial condition. We are highly dependent on our intellectual property. Our success depends significantly on our proprietary technology. We attempt to protect our intellectual property rights through patents and non-disclosure agreements; however, we might not be able to protect our technology, and competitors might be able to develop similar technology independently. 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 patent protection in other countries, including the PRC. The cost of applying for patents in foreign countries and translating the applications into foreign languages requires us to select carefully the inventions for which we apply for patent protection and the countries in which we seek such protection. Generally, our efforts to obtain international patents have been concentrated in the European Union and certain industrialized countries in Asia, including Korea, Japan, and Taiwan. If we are unable to protect our intellectual property successfully, our business, financial condition, and results of operations could be materially and adversely affected. The PRC commercial law is relatively undeveloped compared to the commercial law in the United States. Limited protection of intellectual property is available under PRC law. Consequently, manufacturing our products in the PRC may subject us to an increased risk that unauthorized parties may attempt to copy our products or otherwise obtain or use our intellectual property. We may not be able to protect our intellectual property rights effectively. Additionally, we may not have adequate legal recourse if we encounter infringements of our intellectual property in the PRC. 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 increasing claims from customers and suppliers and increasing 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 brought against us 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 tax” 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 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 cost of repair parts, among other factors. See Note 4. Disposed and Discontinued Operations in Part II, Item 8 "Financial Statements and Supplementary Data" contained herein. 25 Our products may suffer from defects or errors leading to damage 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. If any of our products are defective or fail because of their design, 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. We accrue a warranty reserve for estimated costs to provide warranty services including the cost of technical support, product repairs, and product replacement for units that cannot be repaired. Our estimate of costs to fulfill our warranty obligations is based on historical experience and expectation of future conditions. To the extent we experience increased warranty claim activity or increased costs associated with servicing those claims, our warranty accrual will increase, resulting in decreased gross profit. In recent years, we have experienced increased warranty costs for our legacy inverter product lines, which is reflected in "Income from discontinued operations, net of income taxes." See Note 4. Disposed and Discontinued Operations in Part II, Item 8 "Financial Statements and Supplementary Data" contained herein. 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, most sales made by our foreign subsidiaries are denominated in the currency of the country in which these products are sold and the currency in which they receive payment for such sales could be less valuable at the time of receipt as a result of exchange rate fluctuations. Given recent acquisitions in Europe and Asia, our exposure to fluctuations in the value of the Euro and Chinese Yuan is becoming more significant. From time to time, we enter into forward exchange contracts and local currency purchased options to reduce currency exposures related to likely or pending transactions including those arising from intercompany sales of inventory. However, we cannot be certain that our efforts will be adequate to protect us against significant currency fluctuations or that such efforts will not expose us to additional exchange rate risks, which could materially and adversely affect our results of operations. Recent developments relating to the United Kingdom’s referendum vote in favor of leaving the European Union and related actions could adversely affect us. On June 23, 2016, the United Kingdom (UK) held a referendum in which voters approved an exit from the European Union ("EU"). On January 23, 2020, the UK left the EU, which is commonly referred to as "Brexit". The UK and the EU are now in a transitionary period through the end of 2020. Negotiation on the UK’s withdrawal from the EU as well as its relationship with the EU going forward, including the terms of trade between the UK and the EU, is unclear. Although it is unknown what those terms will be, it is possible that there will be greater restrictions on imports and exports between the UK and EU countries and increased regulatory complexities. These changes may adversely affect our sales, operations and financial results. Our operations in the UK may be adversely affected by extreme fluctuations in the UK exchange rates. Moreover, the imposition of any import restrictions and duties levied on our UK products as imported for EU customers may make our products more expensive for such customers and less competitive from a pricing perspective. Changes in the value of the Chinese yuan could impact the cost of our operation in the PRC and our sales growth in our PRC markets. The PRC 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 may impact our ability to control the cost of our products in the world market. Specifically, the decision by the PRC government to allow the yuan to begin to float against the United States dollar could significantly increase the labor and other costs incurred in the operation of our Shenzhen and Zhongshan facilities and the cost of raw materials, parts, components, and subassemblies that we source in the PRC, thereby having a material and adverse effect on our financial condition and results of operations. 26 Difficulties with our enterprise resource planning ("ERP") system and other parts of our global information technology system could harm our business and results of operation. Like many multinational corporations, we maintain a global information technology system, including software products licensed from third parties. The acquisition of Artesyn’s Embedded Power business adds additional information systems that are initially different from current systems. Any system, network or Internet failures, misuse by system users, government intervention, the hacking into or disruption caused by unauthorized access or loss of license rights could disrupt our ability to timely and accurately manufacture and ship products or to report our financial information in compliance with the timelines mandated by the SEC. Any such failure, misuse, hacking, unauthorized access, disruptions or loss would likely cause a diversion of management’s attention from the underlying business and could harm our operations. In addition, a significant failure of our global information technology system could adversely affect our ability to complete an evaluation of our internal controls and attestation activities pursuant to Section 404 of the Sarbanes-Oxley Act of 2002. If our network security measures are breached and unauthorized access is obtained to a customer’s data or our data or our information technology systems, 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. Unauthorized access to our data, including any regarding our 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, as a result of third-party action, employee error, 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 in order 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 could result in a loss of confidence by our customers, damage our reputation, disrupt our business, lead to legal liability and negatively impact our future sales. 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 user growth or engagement, or otherwise harm our business. Regulatory authorities around the world 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 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. These legislative and regulatory proposals, if adopted, and such interpretations could, in addition to the possibility of fines, result in an order 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. Recent legal developments in Europe have created compliance uncertainty regarding certain transfers of personal data from Europe to the United States. For example, the General Data Protection Regulation ("GDPR"), effective in the EU starting on May 25, 2018, applies to all our activities conducted from an establishment in the EU or related to products and services that we offer to EU users. The GDPR creates a range of new compliance obligations, which could cause us to change our business practices, and will significantly increase financial penalties for noncompliance (including possible fines of up to 4% of global annual turnover for the preceding financial year or €20 million (whichever is higher) for the most serious infringements). Moreover, the China cybersecurity law enacted in 2017 and subsequent regulations and interpretations create compliance and data access risks for multinational corporations such as our Company. 27 The loss of any of our 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 key management, technical, marketing, and sales employees. We may not be successful in retaining our key employees or attracting or retaining additional skilled personnel as required. Failure to retain or attract key personnel could significantly harm our results of operations and competitive position. 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 availability of career development opportunities, and our ability to offer a challenging and rewarding work environment. We must develop our personnel to provide succession plans capable of maintaining continuity during the inevitable unpredictability of personnel retention. While we have plans for key management succession and long-term compensation plans designed to retain our senior employees, if our succession plans do not operate effectively, our business could be adversely affected. We have been, and in the future may again be, involved in litigation. Litigation is costly and could result in further restrictions on our ability to conduct business or make use of market relationships we have developed, or an inability to prevent others from using technology. Litigation may be necessary to enforce our commercial or property rights, to defend ourselves against claimed violations of such rights of others, or to protect our interests in regulatory, tax, customs, commercial, and other disputes or similar matters. In particular, we have been experiencing increased litigation related to our legacy inverter product line and an adverse court ruling in any of our cases could adversely affect our financial condition and results of operations. Litigation often requires a substantial amount of our management’s time and attention, as well as financial and other resources, including: • • • • substantial costs in the form of legal fees, fines, and royalty payments; restrictions on our ability to sell certain products or in certain markets; an inability to prevent others from using technology we have developed; and a need to redesign products or seek alternative marketing strategies. Any of these events could have a significant adverse effect on our business, financial condition, and results of operations. Return on investments or interest rate declines on plan investments could result in additional unfunded pension obligations for our pension plans. 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 plans 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. Pension Liability in Part II, Item 8 "Financial Statements and Supplementary Data" contained herein. Funds associated with our marketable securities that we have traditionally held as short-term investments may not be liquid or readily available. In the past, certain of our investments have been affected by external market conditions that impacted the liquidity of the investment. We do not currently have investments with reduced liquidity, but external market conditions that we cannot anticipate or mitigate may impact the liquidity of our marketable securities. Any changes in the liquidity associated with these investments may require us to borrow funds at terms that are not favorable or repatriate cash from international locations at a significant cost. We cannot be certain that we will be able to borrow funds or continue to repatriate cash on favorable terms, or at all. If we are unable to do so, our available cash may be reduced until those investments can be liquidated. The lack of available cash may prevent us from taking advantage of business 28 opportunities that arise and may prevent us from executing some of our business plans, either of which could cause our business, financial condition or results of operations to be materially and adversely affected. Our intangible assets may become impaired. As of December 31, 2019, we have $202.9 million of goodwill and $184.0 million in intangible assets. We periodically review the estimated useful lives of our identifiable 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 material and adverse effect on our financial position and results of operations and could harm the trading price of our common stock. 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. 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; • • we could be prohibited from offering particular products in specified markets. our production or shipments could be suspended; and 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. Financial reform legislation will result in new laws and regulations that may increase our costs of operations. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") requires various federal agencies to adopt a broad range of new implementing rules and regulations, and to prepare numerous studies and reports for Congress. On August 22, 2012, under the Dodd-Frank Act, the SEC adopted new requirements for companies that use certain minerals and metals, known as conflict minerals, in their products, whether or not these products are manufactured by third parties. These requirements require companies to perform due diligence, disclose and report whether or not such minerals originate from the Democratic Republic of Congo and adjoining countries. We must perform sufficient due diligence to determine whether such minerals are used in the manufacture of our products. With regard to our acquisition of Artesyn, we will need to complete due diligence over the minerals used in the manufacture of those products. In addition, we incur costs to comply with the disclosure requirements, including costs related to determining the source of any of the relevant minerals and metals used in our products. Since our supply chain is complex, we may not be able to sufficiently verify the origins for these minerals and metals used in our products through the due diligence procedures that we implement, which may harm our reputation. In such event, we may also face difficulties in satisfying customers who require that all the components of our products are certified as conflict mineral free. 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 have been especially volatile and have often fluctuated for reasons that are unrelated to their operating performance. In the past, companies that have experienced volatility in 29 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. 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. ITEM 1B. UNRESOLVED STAFF COMMENTS None. 30 ITEM 2.

LEGAL PROCEEDINGS We are presently 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 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. An unfavorable decision in a collection action against a customer we sold products to, or a claim or counterclaim from a customer related to alleged product failures, could also have a material adverse effect on our financial position or reported results of operations. We are engaged presently in such disputes and legal actions with customers and supplier for the inverter product line. 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. For further information see Note 19. Commitments and Contingencies in Part II, Item 8 “Financial Statements and Supplementary Data.” ITEM 4. MINE SAFETY DISCLOSURES Not applicable. 32 PART II ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Principal Market Our common stock is listed on the NASDAQ Global Select Market under the symbol “AEIS.” At February 28, 2020, the number of common stockholders of record was 303. Dividend Policy We have not declared or paid any cash dividends on our capital stock in our history as a public company. We currently intend to retain all future earnings to finance our business or make stock repurchases and do not anticipate paying cash or other dividends on our common stock in the foreseeable future. Purchases of Equity Securities by the Issuer In September 2015, our Board of Directors (the “Board”) authorized a program to repurchase up to $150.0 million of our stock over a thirty-month period. In November 2017, the Board approved an extension of the share repurchase program to December 2019 from its original maturity of March 2018. In May 2018, the Board approved a $50 million increase in the repurchase authorization. On December 18, 2019, the Board authorized to remove the expiration date from the repurchase program and increased the balance available for stock repurchase by $25.1 million. As of December 31, 2019, the Company was authorized to repurchase shares of the Company’s common stock of up to a total of $50.0 million.

All shares repurchased were executed in the open market, and no shares were repurchased from related parties. Repurchased shares are retired and assumed the status of authorized and unissued shares. Accordingly, the associated cost of the repurchased shares was recognized as a reduction to additional paid-in capital. Performance Graph The performance graph below shows the five-year cumulative total stockholder return on our common stock during the period from December 31, 2014 through December 31, 2019. This is compared with the cumulative total 33 return of the NASDAQ Composite Index and the Philadelphia Semiconductor Index (PHLX) over the same period. The comparison assumes $100 was invested on December 31, 2014 in Advanced Energy common stock and in each of the foregoing indices and assumes reinvestment of dividends, if any. Dollar amounts in the graph are rounded to the nearest whole dollar. The performance shown in the graph represents past performance and should not be considered an indication of future performance.

We recognized a tax benefit of $33.8 million, or $0.84 per diluted share, in 2017 related to the continued wind down of our solar inverter business which was discontinued in 2015. 35 (5) In 2015, we discontinued the development, sales and distribution of our solar inverter product line. ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Certain statements set forth below under this caption constitute forward-looking statements. See “Special Note Regarding Forward-Looking Statements” in this Annual Report on Form 10 - K for additional factors relating to such statements and see “Risk Factors” in Item 1A for a discussion of certain risks applicable to our business, financial condition and results of operations. This section of this Form 10-K discusses and compares the results of operations for 2019 and 2018. The discussion and analysis comparing the results of operations for 2017 to 2018 are not included in this Form 10-K and can be found within Part II, Item 7, Management’s Discussion and Analysis for Financial Condition and Results of Operations in our 2018 Form 10-K for the fiscal year ended December 31, 2018. Overview We design, manufacture, sell, and support power conversion products that transform power into various usable forms. Our highly-engineered, mission-critical, precision power conversion, measurement and control solutions enable innovative complex semiconductor manufacturing processes, power medical equipment, control industrial manufacturing processes, provide high efficiency power to data center equipment and deliver efficient and reliable power to communication infrastructure and to a wide range of industrial equipment. Our network of global service support centers provides a recurring revenue opportunity as we offer repair services, conversions, upgrades, and refurbishments and used equipment to companies using our products. Driven by continuing technology migration and changing customer demands, the markets we serve are constantly changing in terms of advancement in applications, core technology and competitive pressures. New products we design for capital equipment manufacturers typically have a lifespan of five to ten years. 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 work with these original equipment 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, and we may win or lose new designs for our existing customers’ or new customers’ next generations of equipment. If existing or new customers do not choose our products as a result of the development, evaluation and qualification efforts related to the design win process, our market share may be reduced, our potential revenues related to the lifespan of our customers’ products, which can be 5 - 10 years, may not be realized, and our business, financial condition and results of operations may be materially and adversely impacted. 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. Operations and Summary of 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. 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, 36 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. The Company believes 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 expense. Revenue Recognition We recognize revenue when we have satisfied our performance obligations which typically occurs when control of the products or completion of services have been transferred to our customers. 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. Shipping and handling fees, if any, are recognized as revenue. The related shipping and handling costs are recognized in cost of sales. Support services include warranty and non-warranty repair services, upgrades, and refurbishments on the products we sell. Repairs that are covered under our standard warranty do not generate revenue. We maintain a credit approval process and we make significant 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 based upon our historical experience and any specific customer collection issues that we have identified. While such credit losses have historically been within our expectations and the provisions established, a significant change in the liquidity or financial position of our customers could have a material adverse impact on the collectability of accounts receivable and our future operating results. Additionally, if our credit loss rates prove to be greater than we currently estimate, we record additional reserves for doubtful accounts. 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 property, plant and equipment and intangible assets, including those with indefinite lives. The estimates also include the fair value of contracts including commodity purchase and sale agreements, storage contracts, and transportation contracts. 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 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. Inventory We value our inventory at the lower of cost (first-in, first-out method) or net realizable value. We regularly review inventory quantities on hand and record a provision to write-down excess and obsolete inventory to its estimated net realizable value, if less than cost, based primarily on our estimated forecast of product demand. Our industry is subject to technological change, new product developments, and changes in end-user demand for our products which can fluctuate significantly. Any significant changes in end-user demand, technology or new product developments could have a significant impact on the value of our inventory and our reported operating results. 37 Warranty Costs We offer warranty coverage for a majority of our products for periods typically ranging from 12 to 24 months after shipment. We provided warranties on our inverter products for five to ten years and also provided the option to purchase additional warranty coverage up to 20 years. Our standard inverter product warranty expense is reported within discontinued 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, in light of 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. See Note 4. Disposed and Discontinued Operations in Part II, Item 8 "Financial Statements and Supplementary Data" for more information on our discontinued operations and Note 15. Warranties in Part II, Item 8 "Financial Statements and Supplementary Data" for more information. Contingencies and Legal Reserves Contingencies and legal reserves are recorded, when probable, using our best estimate of loss. Estimates of loss, when required, are made based on an evaluation of the range of loss related to such matters and where the amount and range can be reasonably estimated. Any such matters are generally resolved over future periods and only when one or more future events occur or fail to occur. Following our initial determination, we regularly reassess and revise the potential liability related to any pending matters as new information becomes available. We disclose pending loss contingencies when the loss is deemed reasonably possible, which requires significant judgment. As a result of the inherent uncertainty of these matters, the ultimate conclusion and actual cost of settlement may materially differ from our estimates. We did not record any significant contingencies or legal reserves during the years ended December 31, 2019 or 2018. See Note 18. Commitments and Contingencies in Part II, Item 8 "Financial Statements and Supplementary Data" for further information. Goodwill, Intangible and Other Long-Lived Assets We evaluate the carrying value of our goodwill for impairment at least annually or when an interim triggering event occurs that would indicate that impairment may have taken place. Our annual impairment test was performed as of December 31st, the last day of our last fiscal quarter. We evaluate our other definite-lived intangible assets for impairment when evidence exists that certain events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. Significant judgments and assumptions are required in such impairment evaluations. The annual impairment test of goodwill may be performed using an assessment of qualitative factors if it is considered more likely than not that goodwill is not impaired. If this qualitative assessment indicates that it is more likely than not that goodwill is impaired, then the next step of impairment testing compares the fair value of a reporting unit to its carrying value. If fair value exceeds carrying value, the we conclude that no goodwill impairment has occurred. Conversely, if carrying value exceeds fair value, we recognize am impairment loss. We evaluate definite-lived intangible assets and other long-lived assets whenever there is an indicator of impairment. 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 . If our expectations of future results and cash flows are significantly diminished, intangible assets, long-lived assets, and goodwill may be impaired and the resulting charge to operations may be material. Changes in these estimates could result in significant revisions to the carrying value of these assets and may result in material charges to our results of operations. 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 38 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." On December 22, 2017, the U.S. enacted the Tax Act into law. Due to the complexity and scope of the Tax Act, the SEC issued SAB 118, which provided for a one-year measurement period from the date of enactment in which to complete the associated tax analysis. This analysis included finalization of the transition tax, re-measuring our U.S. deferred tax assets and liabilities based on the reduction of the corporate income tax rate to 21%, as well as reassessing our indefinite reinvestment position. The analysis of the impact of the Tax Act was completed within the SAB 118 measurement period and are included in the results of operations as of December 31, 2019. Business Environment and Trends Advanced Energy operates in a single segment structure for power electronics conversion products. The acquisition of Artesyn’s Embedded Power business added additional products and market verticals to our business. Following the acquisition, we have continued to be organized on a global, functional basis in order to achieve the anticipated synergies associated with the acquisition. We operate in four vertical markets or applications and provide revenue information to enable tracking of market trends. We also provide information on an organic basis, which is comprised of the Company without Artesyn and LumaSense, and on an inorganic basis, which consists of Artesyn and LumaSense, to improve comparability during the interim periods. The demand environment in each of our markets is impacted by various market trends, customer buying patterns, design wins, macro-economic and other factors. In the fourth quarter of 2019 we saw strengthening demand in semiconductor and datacenter computing markets and weakening demand in our telecom networking market. See below for a further discussion of our market trends. In the beginning of the first quarter of 2020, we began to see an impact of COVID-19 on our operations particularly in China, which has affected both our own workforce and supply chain. This situation is developing rapidly and may continue to affect our operations. See further discussion in Risk Factors above. SEMICONDUCTOR MARKET Growth in the semiconductor market is driven by growing integrated circuits (IC) content across many industries, increased demand for processing and storage in advanced applications such as artificial intelligence or autonomous vehicles, and the rapid adoption of advanced mobile connectivity solutions such as 5G, enhancing existing and enabling new wireless applications. To address the long-term growing demand for semiconductor devices, the industry continues to invest in production capacities for advanced logic devices at the 14nm technology node and beyond, the latest memory devices including 3D-NAND, DRAM and new emerging memories such as MRAM, and back-end test and advanced wafer-level packaging. The industry’s transition to advanced technology nodes in logic and 39 DRAM and to increased layers in 3D memory devices is requiring an increased number of etch and deposition process tools and higher content of our advanced power solutions per tool. As etching and deposition face new challenges such as increasing aspect ratios in advanced 3D devices, more advanced radio frequency (RF) and direct current (DC) technologies are needed, and we are meeting these challenges by providing a broader range of more complex RF and DC power solutions. Beyond etch and deposition processes, the growing complexity at the advanced nodes also drive a higher number of other processes across the fab, including inspection, metrology, thermal, ion implantation, and semiconductor test, 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. The acquisition of Artesyn’s Embedded Power business in September 2019 expanded Advanced Energy’s reach within the Semiconductor Equipment market by targeting back-end test and assembly equipment makers and providing low voltage embedded power content used in auxiliary power applications in semiconductor equipment. Starting in the second half of 2018 and continuing into the first half of 2019, the semiconductor industry went through a period of weakening equipment investment as a result of slowing growth in end market demand for semiconductor devices, ongoing digestion of equipment capacity, and consumption of existing inventory. In the second half of 2019, demand from the semiconductor equipment markets improved from the first half of 2019 as a result of increased investments in advanced logic and foundry equipment and by increased investment by Chinese fabricators, which drove higher demand for our products. Based on limited visibility, we expect demand from the Semiconductor Equipment markets will continue to improve in 2020. However, it is difficult to determine when or if overall market investment in semiconductor capital equipment will return to first half 2018 levels. INDUSTRIAL & MEDICAL MARKETS Customers in the Industrial & Medical markets incorporate our industrial 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, motor drives and connected light-emitting diodes. OEM customers design equipment utilizing our process power technologies in a variety of industrial applications including glass coating, glass manufacturing, flat panel displays, photovoltaics solar cell manufacturing, and similar thin film manufacturing, including data storage and decorative, hard and optical coatings. These applications employ similar technologies to those used in the semiconductor market to deposit films on non-semiconductor substrates. Our strategy around these applications is to leverage our thin film deposition technologies into an expanded set of new materials and applications in adjacent markets. Advanced Energy serves Industrial & Medical markets with mission-critical power components that deliver high reliability, precise, low noise or differentiated power to the equipment they serve. Examples of products sold into Industrial & Medical markets include high voltage products for analytical instrumentation, medical equipment, low voltage power supplies used in applications for medical devices, test and measurement, medical lasers, scientific instrumentation and industrial equipment, and power control modules and thermal instrumentation products for material fabrication, processing and treatment. Our gas monitoring products serve multiple applications in the energy market, air quality monitoring and automobile emission monitoring and testing. Our strategy in the Industrial & Medical markets is to grow and expand our addressable market both organically through our global distribution channels and through acquisitions of products and technologies that are complimentary and adjacent to our core power conversion applications. In 2019 we saw weakening demand for our thin film industrial products driven by macro weakness offset by improvements in medical and other embedded power products and the addition of Artesyn Embedded Power products during the third and fourth quarter of 2019. 40 DATA CENTER COMPUTING MARKETS Following the acquisition of Artesyn’s Embedded Power business in September 2019, Advanced Energy entered the Data Center Computing market with industry-leading products and low-voltage power conversion technologies. We sell to many data center server and storage manufacturers, original design manufacturers of server and storage systems, and cloud service providers, or hyperscalers, who are designing and deploying their own data center server and storage equipment. Driven by the growing adoption of cloud computing and increased consumer internet traffic, market demand for server and storage equipment has shifted from enterprise on-premise computing to the data center. This trend drove a strong year of data center investments in 2018, but the industry moderated investments in the first half of 2019 before recovering in the second half of 2019. With a growing presence at both cloud service providers, hyperscalers, and industry-leading data center server and storage vendors, we believe Advanced Energy is well positioned to continue to capitalize on the ongoing shift towards cloud computing. We generated revenue from the Data Center Computing market during the third and fourth quarters of 2019. TELECOM & NETWORKING MARKETS The acquisition of Artesyn’s Embedded Power business in September 2019 brought us a portfolio of products and technologies that are used across the Telecom & Networking markets. Our customers include many leading vendors and original design manufacturing of wireless and wireline 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 have started to invest in 5G, and this trend is expected to drive demand of our products into the Telecom & Networking markets. In networking, demand is driven by networking investments by telecom service providers and enterprises upgrading of their network, as well as cloud data center networking investments. In the third and fourth quarters of 2019, we generated revenue from the Telecom & Networking markets following the acquisition of Artesyn. Results of Continuing Operations The analysis presented below is organized to provide the information we believe will facilitate an understanding of our historical performance and relevant trends going forward, and should be read in conjunction with our Consolidated Financial Statements, including the notes thereto, in Item 8 "Financial Statements and Supplementary Data" of this Annual Report on Form 10 - K.

Revenue in fiscal 2019 benefited from $220.3 million in inorganic sales from the acquisition of Artesyn’s Embedded Power business and $38.0 million associated with our acquisition of LumaSense. Organic sales in fiscal 2019 decreased $170.8 million primarily due to the overall decline in demand in the semiconductor capital equipment market and lower sales of our industrial thin film products due to a weaker overall macroeconomic environment. Sales in fiscal 2018 includes $17.4 million associated with our acquisition of LumaSense. In 2019, sales to the semiconductor equipment market decreased 24.5% to $403.0 million from $533.8 million in 2018, and decreased to 51.1% of total sales compared to 74.2% of total sales in 2018. The decrease in sales during 2019 is primarily due to an overall decrease in production and demand for semiconductor equipment used in deposition and etch applications, related to advanced memory, and the timing of new technology investment. This was partially offset by strengthening demand for foundry logic equipment late in the fiscal year. Sales to the industrial & medical markets increased 32.9% to $246.0 million in 2019 from $185.1 million in 2018. Our customers in these markets are primarily global and regional original equipment and device manufacturers. Inorganic growth contributed $111.7 million in 2019, while organic sales in the industrial and medical markets decreased $35.8 million, or 21.1%. The decrease in organic sales was primarily due to slowing macro-economic conditions and lower demand in the consumer hard coating and flat panel display markets impacting our thin film deposition markets partially offset by growth in medical and other embedded power products. Sales in the data center computing market were $91.4 million in fiscal 2019 and $0.0 million in fiscal 2018. The increase in data center computing sales is due to the addition of new product verticals through inorganic growth. Sales in the telecom and networking market were $48.5 million in fiscal 2019 and $0.0 million in fiscal 2018. The increase in telecom and networking sales is due to the addition of new product verticals through inorganic growth. Sales to Applied Materials Inc. and Lam Research Corp., our two largest customers, decreased $114.1 million to $253.0 million, and 31.9% of sales, in 2019 from $367.0 million, and 51.1% of sales in 2018. Our sales to Applied Materials Inc. and Lam Research Corp. included sales for the semiconductor capital equipment market, as well as industrial capital equipment used in the solar and flat panel display markets. Backlog Our backlog was $258.9 million at December 31, 2019 as compared to $74.7 million at December 31, 2018. Backlog increased primarily due to the Artesyn acquisition, which added new backlog in the Data Center Computing and Telecom & Networking markets and incremental backlog in Industrial & Medical, as well as strengthening demand for semiconductor equipment late in the fiscal year. GROSS PROFIT Gross profit decreased $50.0 million to $315.6 million, or 40.0%, in 2019 as compared to $365.6 million, or 50.9%, in 2018. The decrease in gross profit as a percent of revenue is due primarily to the mix of products from Artesyn, which carry a lower gross margin, as well as the impact of lower volume, organic product mix and higher freight and customs costs. Gross profit in fiscal 2019 includes $44.8 million and $22.7 million, respectively, from our acquisitions of Artesyn and LumaSense. Gross profit in fiscal 2018 includes 8.3 million associated with our acquisition of LumaSense. 43 OPERATING EXPENSE Research and Development We perform research and development 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. Research and development expenses in 2019 increased $25.5 million to $101.5 million, from $76.0 million in 2018, and increased as a percentage of total revenue to 12.9% in 2019 from 10.6% in 2018. Research and development expenses include $14.2 million and $7.4 million, respectively, from our acquisitions of Artesyn and LumaSense. Research and development expenses in fiscal 2018 include $3.0 million from our acquisition of LumaSense. The increase in research and development expenses is primarily due to increased headcount and material costs 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 $34.6 million to $142.6 million in 2019 as compared to $108.0 million in 2018. SG&A expenses include $19.3 million and $11.3 million, respectively, from our acquisitions of Artesyn’s Embedded Power business and LumaSense. SG&A expenses in 2018 include $6.1 million from our acquisition of LumaSense. Organic SG&A expenses increased by $8.4 million for legal, professional, and transition costs primarily related to the acquisition of Artesyn’s Embedded Power business, as well as a $4.2 million increase in allowance for doubtful accounts related to exposure in China as a result of deferred programs due in part to the recent Coronavirus. Excluding these items, SG&A decreased $2.6 million primarily due to reductions in travel, selling expenses and other outside services as we were able to implement certain cost reduction measures while still preserving recent infrastructure investments in personnel and geographic footprint. Amortization of Intangibles Amortization expense increased $6.4 million to $12.2 million in 2019 from $5.8 million in 2018. The increase in 2019 is primarily driven by incremental amortization of intangible assets related to our acquisition of LumaSense and Artesyn, which we acquired in September of 2018 and 2019, respectively. Restructuring In connection with the restructuring actions management previously put in place to optimize our manufacturing footprint to lower-cost regions, and improvements in operating efficiencies and synergies related to our recent acquisitions including Artesyn, during 2019, we recognized $2.6 million in restructuring charges primarily related to employee termination benefits and recognition of excess lease space as we optimize our facility footprint. During 2019, we paid approximately $5.0 million in severance related costs. 44 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 $12.8 million in 2019, as compared to $0.8 million in 2018. In May 2019 we sold our central solar inverter repair and service operation and recorded a one-time gain of $14.8 million. Other income (expense) excluding the effect of the sale of the central inverter service and repair business was $2.0 million of expense in 2019 as compared to $0.8 million of income in 2018. The decrease in other income is primarily due to higher interest expenses in the second half of 2019 related to the debt issued in connection with the acquisition of Artesyn’s Embedded Power business. Provision for Income Taxes In 2019, we recorded income tax expense for our continuing operations of $10.7 million or an effective tax rate of 15.9%. Income tax expense in 2018 was $25.2 million or an effective tax rate of 14.6%. Included in our 2018 tax expense is $5.7 million of expense associated with finalization of the Tax Act items within the SAB 118 measurement period. After giving consideration to the above item, tax expense in 2018 for our continuing operations would have been $19.5 million or an effective tax rate of 11.3%. The 2019 effective tax rate differs from the federal statutory rate of 21% primarily due to the benefit of tax credits and earnings in foreign jurisdictions which are subject to lower tax rates, offset by additional GILTI tax in the US and withholding taxes. Discontinued Operations In December 2015, we completed the wind down of engineering, manufacturing and sales of our solar inverter product line (the "inverter business"). Accordingly, the results of our inverter business have been reflected as “Income (loss) from discontinued operations, net of income taxes” on our Consolidated Statements of Operations for all periods presented herein. The effect of our sales of the remaining extended inverter warranties to our customers continues to be reflected in deferred revenue 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. Extended warranties related to the inverter product line are no longer offered. In May 2019, we divested our grid-tied central solar inverter repair and service operation. In conjunction with the divesture, the initial product warranty for the previously sold grid-tied central solar inverters was transferred to the buyer. Accordingly, a gain of $8.6 million net of tax expense of $2.4 million was recognized in Other income (expense) and Provision (benefit) for income taxes, respectively, in our discontinued operations for the year December 31, 2019. Operating income from discontinued operations for the year ended December 31, 2019 and 2018, also includes the impacts of changes in our estimated product warranty liability, the recovery of accounts receivable and foreign exchange gain or (losses).

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. 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 Tax Act.

However, we continuously monitor operating price increases, particularly in connection with the supply of component parts used in our manufacturing process. To the extent permitted by competition, we pass increased costs on to our customers by increasing sales prices over time. Sales price increases, however, were not significant in any of the years presented herein. 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 and, cash generated from current operations. At December 31, 2019, we had $346.4 million in cash, cash equivalents, and marketable securities. We believe that adequate liquidity and cash generation will be important to the execution of our strategic initiatives. We believe that our current cash levels and our cash flows from future operations will be adequate to meet anticipated working capital needs, anticipated levels of capital expenditures, and contractual obligations for the next twelve months. At December 31, 2019, we had $125.1 million in cash, cash equivalents, and marketable securities held by foreign subsidiaries. As a result of the recent Tax Act, we have provided for U.S. tax on all foreign unremitted earnings. Accordingly, cash related to these unremitted earnings could be repatriated to the U.S. with minimal additional taxes. Additional taxes would include foreign withholding taxes and U.S. state income taxes. During 2018 and 2019, the Company changed its policy regarding indefinite investment of unremitted earnings, and recognized the tax expense associated with this change in election. Consistent with the Company’s capital deployment initiatives, the Company intends to utilize foreign cash to expand our operations through internal growth and strategic acquisitions, provide for service of existing debt, and opportunistically return cash to stockholders. Credit Facility In connection with the acquisition of Artesyn’s Embedded Power business in 2019, the Company 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 47 facility (“Revolving Facility”). Both the Term Loan Facility and Revolving Facility mature on September 10, 2024. At December 31, 2019, we had $150.0 million in available funding under the Revolving Facility. In connection with the entry into the Credit Agreement, the Company terminated its then-existing Loan Agreement, as amended (the "Loan Agreement"), which previously provided a revolving line of credit of up to $150.0 million subject to certain funding conditions. The Company expensed all unused line of credit fees at the time of termination of the Loan Agreement. See Note 22. Credit Facility in Part II, Item 8 "Financial Statements and Supplemental Data" for additional information. Share Repurchase On December 18, 2019, the Board of Directors authorized to remove the expiration date to the Company’s common stock share repurchase program and increase the authorized amount by $25.1 million increasing the. authorization to repurchase shares up to a total of $50.0 million. As of December 31, 2019, a total of $50.0 million remained available for future share repurchases. We repurchased 1.7 million shares for $95.1 million and 0.4 million shares for $30.0 million in fiscal 2018 and 2017, respectively. There were no shares repurchased in fiscal 2019.

The decrease in net cash flows from operating activities was primarily due to overall decreases in sales to the semiconductor equipment market resulting in decreased earnings from continuing operations. Net cash provided by operating activities in the fourth quarter and full year of 2019 was impacted by net payments due to acquisition related activities and assumed liabilities of approximately $27.0 million, partially offset by receipt of approximately $10.0 million in cash related to the transfer of inventory and other current assets to Smart Global Holdings, Inc. in connection with the completion of the pre-acquisition carve-out of the Embedded Computing business. 48 Net cash used in investing activities Net cash used in investing activities in 2019 was $393.8 million, compared to $113.6 million in 2018. In 2019, we used $366.1 million for the acquisition of Artesyn’s Embedded Power business, as compared to $93.8 million used in 2018 to acquire LumaSense, Trek and the electrostatic technology and product line from Monroe Electronics, Inc. Capital expenditures increased $5.0 million from $20.3 million in 2018 to $25.3 million in 2019 to support new facilities and manufacturing operations. Net cash used in financing activities Net cash provided by financing activities in 2019 was $338.8 million and included the effect of cash proceeds of $350.0 million, net of financing costs of $2.5 million, from our Term Loan Facility, partially offset by $8.8 million in principal repayments. Net cash used in financing activities in 2018 was $97.1 million, which included $95.1 million for the repurchase of company stock.

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 49 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. Operations and Summary of 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, credit facility, and foreign exchange rate risk related to our foreign operations and foreign currency transactions. Interest Rate Risk Our market risk exposure relates to changes in interest rates in our investment portfolio and credit facility. We generally place our investments with high-credit quality issuers and by policy are averse to principal loss and seek to protect and preserve our invested funds by limiting default risk, market risk, and reinvestment risk. As of December 31, 2019, our investments consisted primarily of certificates of deposit with maturity of less than 1 year. As a measurement of the sensitivity of our portfolio and assuming that our investment portfolio balances remain constant, a hypothetical decrease of 100 basis points (1%) in interest rates would decrease annual pre-tax earnings by a nominal amount. As of December 31, 2019, we had $341.3 million of borrowings under our Credit Facility at a rate based on a reserve adjusted Eurodollar Rate or a Base Rate plus an applicable margin. Our quarterly commitments of interest payments are impacted by an increase or decrease of interest rate fluctuations. If our $341.3 million in borrowings had been outstanding for the full year ended December 31, 2019, a hypothetical increase of 100 basis points (1%) in interest rates would increase our commitments by $3.4 million. 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. The functional currencies of our worldwide facilities primarily include the USD, EUR, KRW, TWD, ILS, GBP, and CNY. Our purchasing and sales activities are primarily denominated in the USD, JPY, EUR and CNY. We may be impacted by changes in the relative buying power of our customers, which may impact sales volumes either positively or negatively. As these currencies fluctuate against each other, and other currencies, we are exposed to foreign currency exchange rate risk on sales, purchasing transactions and labor. 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 therefore 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 50 into derivative contract instruments for risk management purposes only. We do not enter into or issue derivatives for trading or speculative purposes. 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 of 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 weighted-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. 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. Effect of currency translation on cash The effect of foreign currency translations on cash had a $1.5 million unfavorable impact for the year ended December 31, 2019 compared to a $1.0 million unfavorable impact for the year ended December 31, 2018. Our foreign operations primarily sell product and incur expenses in the related local currency. Exchange rate 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 adversely impacted. The functional currencies of our worldwide operations include U.S. dollar ("USD"), Canadian Dollar ("CAD"), Swiss Franc ("CHF"), Chinese Yuan ("CNY"), Danish Krone ("DKK"), Euro ("EUR"), Pound Sterling ("GBP"), Israeli New Shekel ("ILS"), Indian Rupee ("INR"), Japanese Yen ("JPY"), Philippines Peso ("PHP"), South Korean Won ("KRW"), Singapore Dollar ("SGD") and New Taiwan Dollar ("TWD"). Our purchasing and sales activities are primarily denominated in USD, CNY, EUR, and JPY. The change in these key currency rates during the years ended December 31, 2019 and 2018 are as follows: Years Ended December 31, To 2019 2018 From 4.7 % (7.9)% CAD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheet of Advanced Energy Industries, Inc. (the Company) as of December 31, 2019, the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for the year ended December 31, 2019, 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, 2019, and the results of its operations and its cash flows for the year ended December 31, 2019, 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, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 2, 2020 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 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 the financial statements are free of material misstatement, whether due to error or fraud. Our audit 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 audit 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 audit provides a reasonable basis for our opinion. Critical Audit Matters The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. Accounting for the acquisition of Artesyn Description of the Matter As described in Note 2 to the consolidated financial statements, during the year ended December 31, 2019, the Company completed the acquisition of Artesyn Embedded Technologies, Inc’s Embedded Power business (“Artesyn”) for a total purchase price of $361.3 million. The transaction was accounted for as a business combination. Auditing the Company's accounting for its acquisition of Artesyn was complex due to the significant estimation required by management in determining the fair value of the identified intangible assets, which primarily consisted of customer relationships of $75.0 million, technology of $28.0 million and tradenames of $21.0 million. The significant estimation was primarily due to the judgmental nature of the inputs to the valuation models used to measure the fair value of these intangible assets, as well as the sensitivity of the respective fair values to the underlying significant assumptions. The 53 significant assumptions used to estimate the fair value of the intangible assets included customer attrition, revenue growth rates, technology obsolescence rates and economic useful lives. These significant assumptions are forward-looking and could be affected by future economic and market conditions. How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design and tested the operating effectiveness of the controls over the Company’s accounting for the acquisition. For example, we tested controls over the valuation of intangible assets, including management’s review of the valuation model and underlying assumptions used to develop the estimated fair value of the intangible assets. To test the estimated fair value of the intangible assets, we performed audit procedures that included, among others, evaluating the Company's valuation methodology and testing the significant assumptions used in the model, as described above, including the completeness and accuracy of the underlying data. For example, we compared the significant assumptions to current industry and market trends, as well as historical results. We also considered how the significant assumptions, specifically technology obsolescence rates, compared to the Company’s prior acquisitions and to Artesyn’s own products. We involved our valuation specialists to assist with our evaluation of the methodology used by the Company and significant assumptions included in the fair value estimates. Accounting for income taxes Description of the Matter As described in Notes 1 and 5 to the consolidated financial statements, the Company is subject to income taxes in the U.S. and numerous foreign jurisdictions, which affect the Company’s provision for income taxes. Specifically, the Company is entitled to claim US foreign tax credits for taxes paid in international tax paying jurisdictions. The Company is also subject to taxation of global intangible low-taxed income (GILTI) earned by foreign subsidiaries. For the year ended December 31, 2019, the Company’s provision for income taxes was $10.7 million. Auditing the Company's provision for income taxes, particularly the effects of foreign tax credits and GILTI, was especially challenging because interpretation of the relevant foreign tax regulations and the application of these interpretations to the calculation of the foreign tax credits and GILTI is highly complex. How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design and tested the operating effectiveness of the controls over the Company’s accounting for income taxes. For example, we tested controls over management’s identification and assessment of changes in applicable tax regulations. We also tested controls over the calculation of the foreign tax credits and GILTI, including review of the completeness and accuracy of the inputs and underlying data. To test the Company’s provision for income taxes, we performed audit procedures that included, among others, evaluating the Company's assessment of applicable tax regulations and testing the calculation of the provision, including the completeness and accuracy of the underlying data. We also evaluated the Company’s significant assumptions and the completeness and accuracy of the data used to determine the amount of the foreign tax credits and GILTI, including foreign earnings and profits, and tested the accuracy of such calculations. As part of these procedures, we engaged tax subject matter professionals with knowledge of and experience with international and local income tax laws to evaluate the application of these regulations to the Company’s tax positions. We have also evaluated the Company’s income tax disclosures included in Note 5 of the consolidated financial statements in relation to these matters. /s/ Ernst & Young LLP We have served as the Company’s auditor since 2019.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (in thousands, except per share amounts) NOTE 1. OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND ESTIMATES 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 from the utility and convert it into various types of highly- controllable usable power that is predictable, repeatable and customizable. We operate in a single segment structure for power electronics conversion products and we operate in four vertical markets or applications to enable tracking of market trends. Our power solutions enable innovation in complex semiconductor and thin film plasma processes such as dry etch, strip, chemical and physical deposition, high and low voltage applications such as process control, computing, networking, telecommunication, analytical instrumentation, medical equipment, industrial technology and temperature- critical thermal applications such as material and chemical processing. We also supply related instrumentation products for advanced temperature measurement and control, electrostatic instrumentation products for test and measurement applications, and gas sensing and monitoring solutions for multiple industrial markets. Our network of global service support centers provides local repair and field service capability in key regions as well as provide upgrades and refurbishment services, and sales of used equipment to businesses that use our products. As of December 31, 2015, we discontinued our Inverter production, engineering, and sales product line. As such, all Inverter revenues, costs, assets and liabilities are reported in Discontinued Operations for all periods presented herein. See Note 4. Disposed and Discontinued Operations for more information. Principles of Consolidation — Our Consolidated Financial Statements include our accounts and the accounts of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. Our Consolidated Financial Statements are stated in United States dollars and have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). 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, and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We believe that the significant estimates, assumptions, and judgments when accounting for items and matters such as allowances for doubtful accounts, excess and obsolete inventory, warranty reserves, acquisitions, asset valuations, asset life, depreciation, amortization, recoverability of assets, impairments, deferred revenue, stock option and restricted stock grants, taxes, and other provisions are reasonable, based upon information available at the time they are made. Actual results may differ from these estimates, making it possible that a change in these estimates could occur in the near term. 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 at 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 US 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, net in our Consolidated Statements of Operations. 61 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) 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). The Company’s 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 at 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. The Company categorizes fair value measurements within the fair value hierarchy based upon the lowest level of the most significant inputs used to determine fair value. 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. The fair value of derivatives is estimated utilizing observable foreign exchange rates adjusted for non-performance credit risk associated with our counterparties. The fair value of contingent consideration and other acquired assets and liabilities associated with the acquisition of Artesyn, are based on Level 3 inputs. There were no transfers of financial assets or liabilities into or from Level 3. The fair value of borrowings approximates the recorded borrowing value based upon market interest rates for similar facilities. See Note 8, Derivative Financial Instruments and Note 22, Credit Facility for additional information. The Company’s non-financial assets, which primarily consist of property and equipment, 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 and indefinite-lived intangible assets), 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. 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 to be cash equivalents, and those with stated maturities of greater than three months as marketable securities. Cash and cash equivalents are highly liquid investments that consist primarily of short-term money market instruments and demand deposits with insignificant interest rate risk and original maturities of three months or less at the time of purchase. Sometimes we invest excess cash in money market funds not insured by the Federal Deposit Insurance Corporation. We believe that the investments in money market funds are on deposit with credit-worthy financial institutions and that the funds are highly liquid. The investments in money market funds are reported at fair value, with interest income recorded in earnings and are included in “Cash and cash equivalents.” Concentrations of Credit Risk — Financial instruments, which potentially subject us to 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. 62 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) We have established an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends, and other information. Accounts Receivable and Allowance for Doubtful Accounts — Accounts receivable are recorded at net realizable value. We maintain a credit approval process and we make significant 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 based upon our historical experience and any specific customer collection issues that we have identified. While such credit losses have historically been within our expectations and the provisions established, there is no assurance that we will continue to experience the same credit loss rates that we have in the past. For example, in the fourth quarter, we increased our allowance for doubtful accounts by $4.2 million relating to a customer exposure in China resulting from economic softness and funding delays causing uncertainty in large program timing which uncertainty is now exacerbated by the spreading Coronavirus. A significant change in the liquidity or financial position of our customers could have a material adverse impact on the collectability of accounts receivable and our future operating results. Changes in allowance for doubtful accounts are summarized as follows: Balances at beginning of period . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ Additions from acquisition . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Inventories are valued at the lower of cost (first-in, first-out method) or net realizable value and are presented net of reserves for excess and obsolete inventory. We regularly review inventory quantities on hand and record a provision to write-down excess and obsolete inventory to its estimated net realizable value, if less than cost, based primarily on historical usage and our estimated forecast of product demand. 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. In addition, our industry is subject to technological change, new product development, and product technological obsolescence that could result in an increase in the amount of obsolete inventory quantities on hand. Therefore, any significant unanticipated changes in demand or technological developments could have a significant impact on the value of our inventory and our reported operating results. Property and Equipment — Property and equipment is 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. Estimated useful lives for financial reporting purposes are as follows: buildings, 20 to 40 years; machinery, equipment, furniture and fixtures and vehicles, 3 to 15 years; and computer and communication equipment, 3 years. Amortization of leasehold improvements is calculated using the straight-line method over the lease term or the estimated useful life of the assets, whichever period is shorter. Leasehold additions and improvements are capitalized, while maintenance and repairs are expensed as incurred. 63 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) 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, net, in our Consolidated Statements of Operations. Purchase accounting — 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 expenses as incurred. 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. The annual impairment test for goodwill can be performed 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 — The Company has incurred debt issuance costs in connections it its debt facilities. Amounts paid directly to lenders are classified as issuance costs. Commitment fees and other costs directly associated with obtaining credit facilities are deferred financing costs which are recorded in the Consolidated Balance Sheets and amortized over the term of the facility. The Company allocates deferred debt issuance costs incurred for its 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. All deferred debt issuance costs are amortized using the effective interest rate method to interest expense within Other income (expense), net on the Company’s Consolidated Statements of Operations. See Note 22. Credit Facility for additional details. Revenue Recognition — We recognize revenue when we have satisfied our performance obligations which typically occurs when control of the products or services have been transferred to our customers. 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. Shipping and handling fees billed to customers, if any, are recognized as revenue. The related cost for shipping and handling fees are recognized in cost of sales. We expense incremental costs of obtaining contracts when the amortization period of the costs is less than 1 year. These costs are included in selling, general, and administrative expenses. Repairs that are covered under our standard warranty do not generate revenue. 64 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) We maintain a worldwide support organization in 10 countries, including the United States, the PRC, Japan, Korea, Taiwan, Germany, Ireland, Singapore, Israel and Great Britain. Support services include warranty and non- warranty repair services, upgrades, and refurbishments on the products we sell. Repairs that are covered under our standard warranty do not generate revenue. As part of our ongoing service business, we satisfy our service obligations under extended warranties and preventive maintenance contracts. Extended warranties had previously been offered on our discontinued inverter products. Any up-front fees received for extended warranties or maintenance plans are deferred and recognized ratably over the service periods, as defined in the agreements. 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 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. Disposed and 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, in light of 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 payment awards made to employees and directors based on estimated fair values. We have estimated the fair value of all stock options and awards on the date of grant using the Black-Scholes-Merton pricing model, which is affected by our stock price, as well as assumptions regarding a number of complex and subjective variables. These variables include our expected stock price volatility over the term of the awards, actual and projected employee option exercise behaviors, risk-free interest rates and expected dividends. We also estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from our estimates. Our expected volatility assumption is based on the historical daily closing price of our stock over a period equivalent to the expected life of the options. 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 a number of 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 65 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) 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. On December 22, 2017, the Tax Act was enacted into law and the new legislation contains several key tax provisions that affected us, including a one-time mandatory transition tax on accumulated foreign earnings and a reduction of the corporate income tax rate to 21%, among others. In conjunction with the Tax Act enactment, the SEC issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act ("SAB 118"), which allowed for the recording of provisional amounts related to the Tax Act and subsequent adjustments related to the Tax Act during an up to one-year measurement period. The Company recorded what it believed to be reasonable estimates during the SAB 118 measurement period which lasted from December 2017 to December 2018. During the quarter ended December 31, 2018, the Company finalized the accounting treatment of the income tax effects of the Tax Act. Although the SAB 118 measurement period has ended, there may be some aspects of the Tax Act that remain subject to future regulations and/or notices which may further clarify certain provisions of the Tax Act. Accordingly, the Company may need to adjust its previously recorded amounts to reflect the recognition and measurement of its tax accounting positions in accordance with Accounting Standards Codification Topic - 740, "Income Taxes" which could be material. Leases — We lease manufacturing and office space under non-cancelable operating leases. 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. Right-of-use assets and operating lease liabilities are recognized at the present value of the future lease payments at 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. Our lease terms include periods under options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Right-of-use assets also include any prepaid lease payments and lease incentives. Operating lease expense is recognized on a straight-line basis over the lease term. 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 66 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) 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 New Accounting Standards Adopted In February 2018, the FASB issued ASU 2018 - 02, "Income Statement—Reporting Comprehensive Income" to give companies the option to reclassify the income tax effects on items within accumulated other comprehensive income resulting from the Tax Act to retained earnings. ASU 2018 - 02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those years. We adopted ASU 2018 - 02 during the first quarter of fiscal year 2019 which did not materially impact our Consolidated Financial Statements. In June 2018, the FASB issued ASU 2018 - 07, "Compensation-Stock Compensation (Topic 718)", Improvements to Non-employee Share-based Payments (“ASU 2018 - 07”). This ASU expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. ASU 2018 - 07 is effective for fiscal years beginning after December 15, 2018. The new guidance is required to be applied retrospectively with the cumulative effect recognized at the date of initial application. We adopted ASU 2018 - 07 during the first quarter of fiscal year 2019 which did not materially impact our Consolidated Financial Statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” to increase transparency and comparability among organizations by recognizing lease right-of-use assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within the year of adoption. We adopted ASU 2016-02 using the modified retrospective approach and recorded $38.2 million of operating lease right-of-use assets and $38.4 million of operating lease liabilities as the cumulative-effect in the first quarter of fiscal year 2019. As of December 31, 2019, we had recorded $105.4 million of operating lease right-of-use assets and $108.9 million of operating lease liabilities. The adoption of ASU 2016-02 did not materially impact the Company’s Consolidated Statement of Operations or Consolidated Statement of Cash Flows for the year ended December 31, 2019. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" and has subsequently issued several supplemental and/or clarifying ASUs (collectively known as "ASC 606"). ASC 606 implements a five- step model for how an entity should recognize revenue in order to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We adopted ASC 606 during the first quarter of fiscal year 2018 using the modified retrospective approach and recorded an adjustment to reflect the cumulative-effect of its adoption on all contracts with customers. New Accounting Standards Issued But Not Yet Adopted In June 2016, the FASB issued ASU 2016 - 13, "Financial Instruments—Credit Losses (Topic 326)", Measurement of Credit Losses on Financial Instruments ("ASU 2016 - 13"). This ASU changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. ASU 2016 - 13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. We are currently assessing the impact ASU 2016 - 13 will have on our Consolidated Financial Statements. In August 2018, the FASB issued ASU 2018 - 13, "Fair Value Measurement (Topic 820)" ("ASU 2018 - 13"). ASU 2018 - 13 modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, based on the concepts in the Concepts Statement, including the consideration of costs and benefits. ASU 2018 - 13 is effective for fiscal years ending after December 15, 2019 and shall be applied to all periods presented on a 67 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) retrospective basis. Early adoption is permitted. We are currently assessing and do not believe ASU 2018 - 13 will have a significant impact on our fair value measurements disclosure requirements. In August 2018, the FASB issued ASU 2018 - 14, "Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715 - 20)" ("ASU 2018 - 14"). ASU 2018 - 14 eliminates requirements for certain disclosures and requires additional disclosures under defined benefit pension plans and other post-retirement plans. ASU 2018 - 14 is effective for fiscal years ending after December 15, 2020 and shall be applied to all periods presented on a retrospective basis. Early adoption is permitted. We are currently assessing and do not believe ASU 2018 - 14 will have a significant impact on our defined benefit plan disclosure requirements. In December 2019, the FASB issued authoritative guidance intended to simplify the accounting for income taxes (ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes”). This guidance eliminates certain exceptions to the general approach to the income tax accounting model, and adds new guidance to reduce the complexity in accounting for income taxes. This guidance is effective for annual periods after December 15, 2020, including interim periods within those annual periods. We are currently evaluating the potential impact of this guidance on our financial statements. NOTE 2. BUSINESS ACQUISITIONS 2019 Acquisitions In September 2019, we completed the acquisition of Artesyn pursuant to the Stock Purchase Agreement (“Acquisition Agreement”), as amended, dated May 14, 2019. Pursuant to the Acquisition Agreement, we acquired all of Artesyn’s issued and outstanding shares for a preliminary purchase price of $361.3 million, net of cash acquired, including the assumption of certain liabilities and subject to an adjustment for net working capital. The purchase price included the contingent consideration related to a potential payment back to the seller per the Acquisition Agreement for any tax benefit arising from the utilization of acquired net operating losses through 2021 at the federal income tax rate of 21.0%. The amount recorded represents our best estimate of the present value of the tax benefit we will achieve utilizing the acquired net operating losses through 2021. In connection with the Acquisition Agreement, we entered into a credit agreement that provided us with aggregate financing of $500.0 million which was used to partially fund the Artesyn acquisition. See Note 22. Credit Facility for additional details related to the credit agreement. Advanced Energy is in the process of finalizing the assessment of fair value for the assets acquired and liabilities assumed related to the Artesyn acquisition. Artesyn’s Embedded Power business is one of the world’s largest providers of highly engineered, application- specific power supplies for demanding applications. This acquisition will diversify our product portfolio and give us access to additional growth markets, including hyperscale data centers, telecom infrastructure in next generation 5G networks, embedded industrial power applications and medical power for diagnostic and treatment applications.

NOTE 3. REVENUE Revenue Recognition We recognize revenue when we have satisfied our performance obligations which typically occurs when control of the products or services have been transferred to our customers. 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. Shipping and handling fees billed to customers, if any, are recognized as revenue. The related shipping and handling costs are recognized in cost of sales. Support services include warranty and non- warranty repair services, upgrades, and refurbishments on the products we sell. Repairs that are covered under our standard warranty do not generate revenue. Nature of goods and services Products 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 electrical power into various usable forms. Our power conversion products refine, modify and control the raw electrical power from a utility and convert it into power that is predictable, repeatable and customizable. Our products enable thin film manufacturing processes such as plasma enhanced chemical and physical deposition and etch for various semiconductor and industrial products, industrial thermal applications for material and chemical processes, and specialty power for critical industrial technology applications. We also supply thermal instrumentation products for advanced temperature measurement and control in these markets. As a result of the Artesyn acquisition, we now sell precision power conversion products into the telecom and networking, data center, and additional medical and industrial markets. 72 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) Our products are designed to enable new process technologies, improve productivity, and lower the cost of ownership for our customers. We also provide repair and maintenance services for all our products. We principally serve original equipment manufacturers ("OEM") and end customers in the semiconductor, flat panel display, high voltage, solar panel, telecom and networking, data center, medical, and other industrial capital equipment markets. Our advanced power products are used in diverse markets, applications, and processes including the manufacture of capital equipment for semiconductor device manufacturing, thin film applications for thin film renewables and architectural glass, and for other thin film applications including flat panel displays, and industrial coatings. Our embedded power products are used in a wide range of applications, including 5G, datacenter including hyperscale and other industrial and medical applications. Services Our global support services group offers warranty and after-market repair services in the regions in which we operate, providing us with preventive maintenance opportunities. Our customers continue to pursue low cost of ownership of their capital equipment and are increasingly sensitive to the costs of system downtime. They expect that suppliers offer comprehensive local repair service and customer support. To meet these market requirements, we maintain a worldwide support organization comprising of both direct and indirect activities, through partnership with local distributors, primarily in the United States ("U.S."), the People’s Republic of China ("PRC"), Japan, South Korea, Taiwan, Germany, Singapore and United Kingdom. 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. We record a contract liability for payments received for extended warranties or maintenance plans for which we have not yet provided the services. Revenue under these arrangements is recognized ratably over the underlying terms as we do not have historical information which would allow us to project the estimated service usage pattern at this time. In May 2019, we sold our grid-tied central inverter repair and service operation to a third party. In connection with this sale, approximately $22.0 million of deferred revenue related to extended warranties and service contracts, were transferred to the buyer. See Note 4. Disposed and Discontinued Operations below for additional information. Contract liabilities related to our extended warranties and service contracts were $9.2 million as of December 31, 2019 and $33.4 million as of December 31, 2018. We expect to recognize between $0.2 million and $1.0 million per year through 2031.

DISPOSED AND DISCONTINUED OPERATIONS Disposed Operations In May 2019, we sold our grid-tied central solar inverter services business to Bold Renewables Holdings, LLC (“Buyer”) for $1.00 dollar and assumption of our initial product warranty and our extended warranty service obligations. In connection with this transaction, we entered into a Loan and Security Agreement with the Buyer. Under this agreement, we initially loaned $2.8 million to the buyer at closing and loaned an additional $1.5 million in the fourth quarter of 2019. We have made available an additional $3.75 million that may be borrowed in the future, subject to certain operating and liquidity covenants, for operating needs over the next ten years. The borrowings under the Loan and Security Agreement bear interest at 0% for the first seven years and 5% thereafter. Additionally, the Loan and Security Agreement provides for early payment discounts of 50% during the first three years, 45% for years four and five and 40% thereafter up to 30 days prior to the maturity of the Loan and Security Agreement. A discount on the initial $2.8 million funding under the Loan and Security Agreement of $2.3 million has been recognized as a reduction to the gain recognized on the sale. As a result of the transaction, we reduced our liabilities held in discontinued operations approximately $10.9 million related to initial product warranty and reduced Other liabilities of our continuing operations of approximately $22.0 million related to extended warranty service obligations as well as other assets and liabilities associated with the continuing grid-tied central solar inverter service and repair business. A $14.8 million non-cash gain was recognized in Other income (expense), net from continuing operations and an $8.6 million non-cash gain, net of tax expense of $2.4 million, was recognized in Income from discontinued operations. Discontinued Operations In December 2015, we completed the wind down of engineering, manufacturing and sales of our solar inverter product line (the "inverter business"). Accordingly, the results of our inverter business have been reflected as “Income (loss) from discontinued operations, net of income taxes” on our Consolidated Statements of Operations for all periods presented herein. The effect of our sales of extended inverter warranties to our customers continues to be reflected in deferred revenue 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 74 ADVANCED ENERGY INDUSTRIES, INC.

The Company’s effective tax rate differs from the U.S. federal statutory rate of 35% for the year ended December 31, 2017, primarily due to the benefit related to the wind down of our solar inverter business and earnings in foreign jurisdictions, which are subject to lower tax rates, offset by the impact of U.S. tax reform.

As of December 31, 2019, the Company has recorded a valuation allowance on $16.0 million of its U.S. domestic deferred tax assets, largely attributable to acquired federal capital loss carryforwards for which the Company does not have sufficient income in the character to realize that attribute, and 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 $60.2 million and is associated primarily with operations in Austria, Germany, Hong Kong and Switzerland. As of December 31, 2019, 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, 2019 valuation allowance balance reflects an increase of $45.3 million during the year. The change in the valuation allowance is primarily due to increases from acquired Artesyn positions and current year activity, partially offset by decreases due to foreign exchange movements As of December 31, 2019, the Company had U.S., foreign and state tax loss carryforwards of $54.4 million, $206.8 million, and $146.2 million, respectively. Additionally, the Company had $40.7 million and $32.9 million of capital loss and interest expense limitation carryforwards, respectively. Finally, the Company had U.S. and state tax credit carryforwards of $3.8 million and $1.8 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 77 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) the case of the interest expense limitation amount, no expiration period. The majority of the foreign jurisdiction, and $4.6 million of the federal net operating loss carry forwards, have no expiration period. We operate under a tax holiday in one of our foreign jurisdictions. This tax holiday is in effect through June 30, 2027. The tax holiday is conditional upon our meeting certain employment and investment thresholds. The impact of the tax holiday decreased foreign taxes by $4.0 million and $17.8 million for 2019 and 2018, respectively. The benefit of the tax holiday on earnings per diluted share was $0.12 and $0.47 for 2019 and 2018, respectively. In the third quarter of 2019, following a review of our operations, liquidity and funding, tax implications of cash repatriation, political risk, and investment opportunities, we determined that the ability to access certain amounts of foreign earnings that were previously indefinitely reinvested would provide greater investment returns, treasury controls, and other working capital needs if repatriated to the U.S. Accordingly, in the third quarter of 2019, we withdrew the permanent reinvestment assertion on $123.9 million of earnings generated by certain of our operations through December 2018. Resulting from this change in permanent reinvestment assertion, the Company recorded a deferred tax liability of $2.9 million related to withholding and state income taxes. There is no certainty as to the timing of when such foreign earnings will be distributed to the United States in whole or in part. Certain foreign subsidiary earnings are subject to U.S. taxation under the U.S. Tax Act, which also repeals U.S. taxation on the subsequent repatriation of those earnings. We have not provided for U.S. state or foreign income taxes on $26.5 million of our subsidiaries’ undistributed earnings as of December 31, 2019. The $26.5 million of undistributed foreign earnings continue to be reinvested in our foreign operations, as we have determined that these earnings are necessary to support our planned growth and strategic acquisitions in our foreign operations, and as a result, these earnings remain indefinitely reinvested in those operations. In making this decision, we considered cash needs for investing in our existing businesses, currency controls, and the tax cost of cash repatriation. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable. We account for uncertain tax positions by applying a minimum recognition threshold to tax positions before recognizing these positions in the financial statements. The reconciliation of our total gross unrecognized tax benefits is as follows: Years Ended December 31, 2018 2017 2019 Balance at beginning of period . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 13,162 $ 15,990 $ 11,401 1,258 Additions based on tax positions taken during a prior period . . . . . . . . . . . . . . . . . . . . . — Additions based on tax positions taken during a prior period - acquisitions . . . . . . . . . . 4,433 Additions based on tax positions taken during the current period . . . . . . . . . . . . . . . . . . — Reductions based on tax positions taken during a prior period . . . . . . . . . . . . . . . . . . . .

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 $3.0 million and $1.2 million of accrued interest and penalties at December 31, 2019 and 2018, respectively. We expect the total amount of tax contingencies will decrease by approximately $3.5 million in 2020 based on statute of limitation expiration. 78 ADVANCED ENERGY INDUSTRIES, INC.

NOTE 6. EARNINGS PER SHARE Basic earnings per share (“EPS”) is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the denominator is increased 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, and if such assumed conversion is dilutive.

In November 2017, our Board of Directors approved an extension of the share repurchase program to December 2019 from its original maturity of March 2018. In May 2018, our Board of Directors approved a $50 million increase in its authorization to repurchase shares of our common stock under this same program. On December 18, 2019, the Board of Directors authorized to remove the expiration date to the Company’s share repurchase program and increase the authorized amount by $25.1 million. As of December 31, 2019, the Company is authorized to repurchase shares of the Company’s common stock of up to a total of $50.0 million. 79 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) In order to execute the repurchase of shares of our common stock, the Company periodically enters into stock repurchase agreements.

The maturities of our certificates of deposit as of December 31, 2019 ranged from March 18, 2020 to October 17, 2020. The value and liquidity of the marketable securities we hold are affected by market conditions, as well as the ability of the issuers of such securities to make principal and interest payments when due, and the functioning of the markets in which these securities are traded. As of December 31, 2019, we do not believe any of the underlying issuers of our marketable securities are at risk of default. NOTE 8. DERIVATIVE FINANCIAL INSTRUMENTS We are impacted by changes in foreign currency exchange rates. We may manage these risks through the use of derivative financial instruments, primarily forward contracts with banks. During the years ended December 31, 2018 and 2017, we entered into foreign currency exchange forward contracts to manage the exchange rate risk associated with intercompany debt denominated in nonfunctional currencies. These derivative instruments are not designated as hedges; however, they do economically offset the fluctuations of our intercompany debt due to foreign exchange rate changes. These forward contracts are typically for one-month periods. We did not have any currency exchange rate forward contracts outstanding as of December 31, 2019 and 2018. At December 31, 2017, we had outstanding Euro and Pound Sterling forward contracts. The notional amount of foreign currency exchange forward contracts outstanding at December 31, 2017 was $16.3 million and the fair value of these contracts was not significant at December 31, 2017. During the years ended December 31, 2019, 2018, and 2017, the gains and losses recorded related to the foreign currency exchange rate forward contracts are as follows: Foreign currency loss from foreign currency exchange rate forward contracts . . . . . $ 2019 Years Ended December 31, 2018 (750) $ (1,438) — $ 2017 These gains and losses were offset by corresponding foreign currency gains and losses on the related intercompany debt and both are included as a component of Other income (expense), net, in our Consolidated Statements of Operations. 80 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) During the first quarter of 2017, we entered into a foreign currency exchange rate forward contract at a cost of $3.5 million, to mitigate the exchange rate risk associated with a planned offshore acquisition which was not consummated. The hedge expired upon maturity in the first quarter of 2017. The cost of the forward contract is recorded as a component of Other income (expense), net in our Consolidated Statement of Operations.

These receivables are all short term in nature and do not include any financing components. Unbilled receivables consist of amounts where we have satisfied our contractual obligations related to inventory stocking contracts with customers. Such amounts are typically invoiced to the customer upon their consumption of the inventory managed under the stocking contracts. We anticipate that substantially all unbilled receivables will be invoiced and collected over the next twelve months. These contracts do not include any financing components. NOTE 10.

LEASES The Company adopted authoritative guidance related to leases effective January 1, 2019 using the modified retrospective method. The comparative information presented in the Consolidated Financial Statements was not restated and is reported under the accounting standards in effect for the periods presented. See the section Leases in Note 1. Operations and Summary of Significant Accounting Policies and Estimates for a discussion of the significant changes resulting from adoption of the guidance. The Company’s leases consist primarily of manufacturing and office space under non-cancelable operating leases expiring at various dates through 2033. Leases with an original term of twelve months or less are not reported in the Consolidated Balance Sheet; expense for these short-term leases is recognized on a straight-line basis over the lease term. Most leases include one or more options to renew. The exercise of these renewal options is at the Company’s 84 ADVANCED ENERGY INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) discretion. We regularly evaluate the renewal options and when they are reasonably certain of exercise, we include the renewal period in the lease term, the right-of-use assets and lease liabilities. Due to the Company’s centralized treasury function, the Company utilizes a portfolio approach to discount its lease obligations. The Company assesses the expected lease term at lease inception and discounts the lease using a fully secured annual incremental borrowing rate, adjusted for time value corresponding with the expected lease term. New leases are negotiated and executed to meet business objectives on an on-going basis. During the first fiscal quarter of 2020, we expect to record additional right of use assets and related liabilities for facilities in Fort Collins, Colorado, USA. The lease extensions in Fort Collins, Colorado commenced in January 2020 and extended the expected lease terms to 16 years; the right of use asset and operating lease liability recorded at commencement will be $21.8 million.

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 as determined by law. Participants are immediately vested in their contributions. Profit-sharing contributions to the plan, which are discretionary, are approved by the Board of Directors. Vesting in the profit-sharing contribution account is based on years of service, with most participants fully vested after four years of credited service. For the years ended December 31, 2019, 2018, and 2017 our contribution for participants in our 401(k) plan was based on matching 50% of contributions made by employees up to 6% of the employee’s compensation. During the years ended December 31, 2019, 2018, and 2017 we recognized total defined contribution plan costs of $1.6 million, $1.4 million, and $1.1 million, respectively. Defined Benefit Plan We maintain defined benefit pension plans for certain of our non-U.S. employees in the U.K., Germany, and Philippines. Each plan is managed locally and in accordance with respective local laws and regulations. In order to measure the expense and related benefit obligation, various assumptions are made including discount rates used to value the obligation, expected return on plan assets used to fund these expenses and estimated future inflation rates. These assumptions are based on historical experience as well as facts and circumstances. An actuarial analysis is used to measure the expense and liability associated with pension benefits. In connection with the acquisition of Artesyn in September of 2019, the Company acquired certain pension plans and, as a result, started including the related balances in its Consolidated Balance Sheets at December 31, 2019 and the expenses attributable to these plans for the period from September 10, 2019 to December 31, 2019 in its Consolidated Statement of Operations. See Note 2. Business Acquisitions for more details on this transaction. 86 ADVANCED ENERGY INDUSTRIES, INC.

The asset and growth funds aim to generate an ‘equity-like’ return over an economic cycle with significantly reduced volatility relative to equity markets and have 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. The bond fund and gilt fund are invested in index-linked gilts and corporate bonds. 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 expectations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (continued) (in thousands, except per share amounts) NOTE 18. STOCK-BASED COMPENSATION As of December 31, 2019, we had two active stock-based incentive compensation plan: the 2017 Omnibus Incentive Plan and the Employee Stock Purchase Plan (“ESPP”). All new equity compensation grants are issued 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. Our stock plans are administered by the Board of Directors Compensation Committee. At December 31, 2019, there were 3.3 million shares reserved and 2.5 million shares available for future grant under our stock-based incentive plans. On May 4, 2017, the stockholders approved the Company’s 2017 Omnibus Incentive Plan ("the 2017 Plan") and reserved 5.2 million shares under the plan. The 2017 Plan replaced the 2008 Omnibus Incentive Plan ("the 2008 Plan"), and all awards previously granted under the 2008 Plan continue to vest and/or are exercisable under the 2017 Plan in accordance with their original terms and conditions. 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. Additionally, awards issued may be issued as performance-based awards to align stock compensation awards to the attainment of annual or long-term performance goals. As of December 31, 2019, there were 2.3 million shares available for grant under the 2017 Plan. The Company grants restricted stock units and performance stock units. The grant date fair values of restricted stock units and performance stock units are based on the closing market price of our common stock on the grant date. Our restricted stock units vest based on continued service. Our performance stock units vest based on achievement of certain performance goals and certification of performance achievement by the Compensation Committee of the Board of Directors. Stock-based compensation expense, net of forfeitures, is recognized on a straight-line basis over the requisite service period. For performance stock units, compensation expense is updated for the Company’s expected performance level against performance goals at the end of each reporting period, which involves judgment as to achievement of certain performance metrics. 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 for the three years ended December 31 is as follows: Stock-based compensation expense . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 7,327 $ 9,703 $ 12,549 Our stock-based compensation expense is based on the value of the portion of share-based payment awards that are ultimately expected to vest, assuming estimated forfeitures at the time of grant. Estimated forfeiture rates for our stock-based compensation expense applicable to stock options and restricted stock units ("RSU’s") was approximately 10%, 10% and 17% for the years ended December 31, 2019, 2018 and 2017, respectively.

As of December 31, 2019, there was $5.9 million of total unrecognized compensation cost, net of expected forfeitures related to non-vested RSUs granted, which is expected to be recognized through fiscal November 2022, with a weighted-average remaining vesting period of 1.3 years. Stock Options Stock option awards are generally granted 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 as determined at the time of grant. Stock option awards generally have a term of 10 years. The fair value of options granted during the year ended December 31, 2015 was estimated on the date of grant using the Black-Scholes-Merton option pricing model using the following assumptions: the risk-free interest rate was 1.1% - 1.4%, the expected term was 4.3 years and expected volatility was 43%. The risk-free interest rate was based on the five-year U.S. Treasury Bill at the time of the grant. We utilize our historical experience in determining the expected term of our stock options and volatility of our common stock. We have not historically issued dividends. Changes in our outstanding stock options during the years ended December 31, 2019, 2018 and 2017 were as follows: 2019 Weighted- Average Exercise Price 2018 Weighted- Average Exercise Price 2017 Weighted- Average Exercise Shares Shares Shares Price Options outstanding at beginning of period. . . . . . . . . . . . . . . . . .

In May 2010, stockholders approved an increase from 500,000 to 1,000,000 shares authorized for sale under our ESPP. Employees below the Vice President level are eligible to participate in the ESPP if employed by us 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. At December 31, 2019, 0.2 million shares remained available for future issuance under the ESPP. Purchase rights granted under the ESPP are valued using the Black-Scholes-Merton model. As of December 31, 2019, there was $0.2 million of total unrecognized compensation cost related to the ESPP that is expected to be recognized over a remaining period of five months. Total compensation expense was $0.5 million for the year ended December 31, 2019 and $0.4 million for the year ended December 31, 2018, and $0.2 million for the year ended December 31, 2017.

COMMITMENTS AND CONTINGENCIES Disputes and Legal Actions 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 patent 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 patent 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. The Company is currently not a party to any legal action that the Company believes would reasonably have a material adverse impact on its business, financial condition, results of operations or cash flows.

NOTE 22. CREDIT FACILITY In September 2019, in connection with the Artesyn Acquisition Agreement, the Company 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”). Both the Term Loan Facility and Revolving Facility mature on September 10, 2024. The Revolving Facility and Term Loan Facility bear interest, at the option of the Company, at a rate based on a reserve adjusted Eurodollar Rate or a Base Rate, as defined in the Credit Agreement, plus an applicable margin. Additionally, the Revolving Facility is subject to an unused line fee. As of December 31, 2019, the effective interest rate for the Revolving Facility and Term Loan Facility was 2.55% and the effective rate for the unused line fee was 0.10%. As of December 31, 2019, the Company had $150.0 million available to withdraw on the Revolving Facility and was in compliance with all covenants.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE On March 25, 2019, the Audit Committee (the “Audit Committee”) of the Board of Directors (the “Board”) of Advanced Energy Industries, Inc. (the “Company”) dismissed Grant Thornton LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm, effective immediately, and provided Grant Thornton with notice of such dismissal. During the Company’s two most recent fiscal years ended December 31, 2018 and December 31, 2017, and during the subsequent interim period through March 25, 2019, (i) there were no disagreements (as that term is described in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with Grant Thornton on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreement(s), if not resolved to Grant Thornton’s satisfaction, would have caused Grant Thornton to make reference to the subject matter of the disagreement(s) in connection with its reports, and (ii) there were no “reportable events” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K). On March 27, 2019, the Company engaged Ernst & Young LLP (“E&Y”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2019, which engagement was approved by the Audit Committee and effective on March 27, 2019. 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 (the "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 Act is accumulated and communicated to management, including our Principal Executive Officer (Yuval Wasserman, Chief Executive Officer) and Principal Financial Officer (Paul Oldham, Chief Financial Officer & Executive Vice President), 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, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2019. The conclusions of the Chief Executive Officer and Chief Financial Officer from this evaluation were communicated to the Audit Committee. We intend to continue to review and document our disclosure controls and procedures, including our internal controls and procedures for 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 September 2019, we acquired Artesyn Embedded Technologies, Inc.’s Embedded Power business (“Artesyn”), as discussed in Note 2. Business Acquisitions in Item 8 "Financial Statements and Supplementary Data." The objectives of Artesyn established internal controls over financial reporting is consistent, in all material 97 respects, with Advanced Energy’s objectives. We are in the process of completing a more comprehensive review of Artesyn’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 and the changes that are anticipated to be made, and in accordance with the general guidance issued by the SEC regarding exclusion of certain acquired businesses, we have excluded Artesyn from the December 31, 2019 assessment of Advanced Energy’s internal controls over financial reporting. Artesyn accounted for approximately 45% of Advanced Energy’s total assets at December 31, 2019, and 28% of Advanced Energy’s total net sales for the fiscal year ended December 31, 2019. 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, 2019, 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, 2019. 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 attestation report, included herein, on the effectiveness of our internal control over financial reporting as of December 31, 2019. Changes in Internal Control over Financial Reporting There was no change in our internal control over financial reporting that occurred during 2019 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. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and the Board of Directors of Advanced Energy Industries, Inc. Opinion on Internal Control Over Financial Reporting We have audited Advanced Energy Industries, Inc.’s internal control over financial reporting as of December 31, 2019, 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, 2019, 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 Artesyn Embedded Technologies, Inc.’s Embedded Power business which was acquired during the year ended December 31, 2019, which are included in the 2019 consolidated financial statements of the Company and constituted 45% of total assets as of December 31, 2019 and 28% of sales 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 this entity. 98 We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2019, the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for the year ended December 31, 2019, and the related notes and our report dated March 2, 2020 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. /s/ Ernst & Young LLP Denver, Colorado March 2, 2020 ITEM 9B.
