Advanced Energy Industries, Inc., a Delaware corporation, and its consolidated subsidiaries ("we," "us," "our," "Advanced Energy," or the "Company") design, manufacture, sell, and support precision power products that transform, refine, and modify the raw electrical power coming from either the utility or the building facility and convert it into various types of highly controllable, usable power that is predictable, repeatable, and customizable to meet the necessary requirements for powering a wide range of complex equipment.

Our plasma power solutions enable innovation in complex semiconductor and thin film plasma processes such as dry etch, strip and deposition. Our broad portfolio of high and low voltage power products are used in a wide range of applications, such as semiconductor equipment, industrial production, medical and life science equipment, data center and telecommunication. We also supply related sensing, controls, and instrumentation products for advanced measurement and calibration of radio frequency ( " RF " ) power and temperature, 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 a recurring revenue opportunity as we offer repair services, conversions, upgrades, refurbishments, and used equipment to companies using our products.

In management's opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal, recurring adjustments, necessary to present fairly the financial position of the Company as of June 30, 2022, and the results of our operations and cash flows for the three and six months ended June 30, 2022 and 2021.

The unaudited consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been omitted pursuant to such rules and regulations. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2021 and other financial information filed with the SEC.

Use of Estimates in the Preparation of the Consolidated Financial Statements

The preparation of our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The significant estimates, assumptions, and judgments include, but are not limited to:

● excess and obsolete inventory; ● pension obligations; ● acquisitions and asset valuations; and ● taxes and other provisions.

Significant Accounting Policies

Our accounting policies are described in Note 1 to our audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2021 .

We reclassified certain prior period amounts within these consolidated financial statements to conform to the current year presentation.

New Accounting Standards

From time to time, the Financial Accounting Standards Board ("FASB") or other standards setting bodies issue new accounting pronouncements. Updates to the FASB Accounting Standards Codification ("ASC") are communicated through issuance of an Accounting Standards Update ("ASU"). Unless otherwise discussed, we believe that the impact of recently issued guidance, whether adopted or to be adopted in the future, will not have a material impact on the consolidated financial statements upon adoption.

New Accounting Standards Adopted

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

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

New Accounting Standards Issued But Not Yet Adopted

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04"). In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848): Scope" ("ASU 2021-01"). This collective guidance provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate that is expected to be discontinued. ASU 2020-04 and ASU 2021-01 will be in effect through December 31, 2022. We are currently assessing the potential impact of ASU 2020-04 and ASU 2021-01 on our consolidated financial statements.

Our Credit Facility (refer to Note 18. Credit Facility ) and interest rate swap agreements (refer to Note 7. Derivative Financial Instruments ) reference the one-month USD LIBOR rate. Both agreements contain provisions for transition to a new reference rate upon discontinuance of LIBOR. We expect the one-month USD LIBOR rate to be available through June 2023. We are currently assessing the potential timing of transitioning to a replacement interest rate benchmark for our Credit Facility and do not expect ASU 2020-04 and ASU 2020-01 to materially impact our consolidated financial statements.

(In thousands, except per share data)

As part of our ongoing service business, we satisfy our service obligations under preventative maintenance contracts and extended warranties which had previously been offered on our discontinued inverter products. Any up-front fees received for extended warranties or maintenance plans are deferred. Revenue under these arrangements is recognized ratably over the underlying terms as we do not have historical information which would allow us to project the estimated service usage pattern at this time.

Performance obligations

Our unsatisfied performance obligations primarily relate to customer purchase orders for products we have not yet shipped. We expect to fulfill the majority of these performance obligations within one year. As a result, we elected not to disclose the amount of these remaining performance obligations.

NOTE 4. INCOME TAXES

The following table summarizes tax expense and the effective tax rate for our income from continuing operations:

​	​	​	​	​	​	​	​	​	​	​	​	​	​
​	​	Three Months Ended June 30,					​	Six Months Ended June 30,					​
​		2022			2021			2022			2021		​
Income from continuing operations, before income taxes	​	$	56,014	​	$	37,418	​	$	99,829	​	$	81,093	​
Provision for income taxes	​	$	11,203	​	$	1,876	​	$	18,156	​	$	7,160	​
Effective tax rate	​	​	20.0	%	​	5.0	%	​	18.2	%	​	8.8	%

Our effective tax rates differ from the U.S. federal statutory rate of 21 % for the three and six months ended June 30, 2022 and 2021, respectively, primarily due to the benefit of earnings in foreign jurisdictions which are subject to lower tax rates, as well as tax credits, partially offset by net U.S. tax on foreign operations. The effective tax rate for both the three and six months ended June 30, 2022 was higher than the same periods in 2021 primarily driven by the global impact to our provision from capitalizing and amortizing research and development expenses rather than immediately expensing them starting in 2022 as required by the 2017 Tax Cuts and Jobs Act. Congress has proposed tax legislation to delay the effective date of this change, but it is uncertain whether the proposed delay will ultimately be enacted into law. Additionally, there were beneficial discrete events in 2021 that did not recur in 2022.

NOTE 5. EARNINGS PER SHARE

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

The following is a reconciliation of the weighted-average shares outstanding used in the calculation of basic and diluted earnings per share:

​	​	​	​	​	​	​	​	​	​	​	​	​	​
​	​	Three Months Ended June 30,					​	Six Months Ended June 30,					​
​		2022			2021			2022			2021		​
Income from continuing operations	​	$	44,811	​	$	35,542	​	$	81,673	​	$	73,933	​
Less: income from continuing operations attributable to noncontrolling interest	​		21	​		31	​		7	​		64	​
Income from continuing operations attributable to Advanced Energy Industries, Inc.	​	$	44,790	​	$	35,511	​	$	81,666	​	$	73,869	​
​	​	​	​	​	​	​	​	​	​	​	​	​	​
Basic weighted-average common shares outstanding	​		37,520	​		38,389	​		37,535	​		38,359	​
Assumed exercise of dilutive stock options and restricted stock units	​		190	​		197	​		219	​		230	​
Diluted weighted-average common shares outstanding	​		37,710	​		38,586	​		37,754	​		38,589	​
​	​	​	​	​	​	​	​	​	​	​	​	​	​
Continuing operations:	​			​			​			​			​
Basic earnings per share	​	$	1.19	​	$	0.93	​	$	2.18	​	$	1.93	​

The fair value of foreign currency forward contracts is based on the movement in the forward rates of foreign currency cash flows in which the hedging instrument is denominated. We determine the fair value of interest rate swaps by estimating the net present value of the expected cash flows based on market rates and associated yield curves, adjusted for non-performance credit risk, as applicable. See Note 7. Derivative Financial Instruments for additional information. The fair value of contingent consideration is determined by estimating the net present value of the expected cash flows based on the probability of expected payment. For all periods presented, there were no transfers into or out of Level 3.

NOTE 7. DERIVATIVE FINANCIAL INSTRUMENTS

Changes in foreign currency exchange rates impact us. We may manage these risks through the use of derivative financial instruments, primarily forward contracts with banks. These forward contracts manage the exchange rate risk associated with assets and liabilities denominated in nonfunctional currencies. Typically, we execute these derivative instruments for one-month periods and do not designate them as hedges; however, they do economically offset the fluctuations of our assets and liabilities due to foreign exchange rate changes.

The following table summarizes the notional amount of outstanding foreign currency forward contracts:

​	​	​	​	​
​	​	June 30,	​	December 31,
​		2022		2021
Foreign currency forward contracts	​	$ 63,743	​	$ —

Gains and losses related to foreign currency exchange contracts were offset by corresponding gains and losses on the revaluation of the underlying assets and liabilities. Both are included as components of other income (expense), net in our Consolidated Statements of Operations.

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

The interest rate swap contracts fixed a portion of the outstanding principal balance on our term loan to a total interest rate of 1.271 %. This is comprised of 0.521 % average fixed rate per annum in exchange for a variable interest rate based on one-month USD-LIBOR-BBA plus the credit spread in our existing Credit Agreement (see Note 18. Credit Facility ), which is 75 basis points at current leverage ratios.

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

​	​	​	​	​
​	​	June 30,	​	December 31,
​		2022		2021
Interest rate swap contracts	​	$ 246,969	​	$ 255,719

The following table summarizes the balances recorded in accumulated other comprehensive loss on the Consolidated Balance Sheets for qualifying hedges.

​	​	​	​	​
​	​	June 30,	​	December 31,
​		2022		2021
Interest rate swap contract gains	​	$ 9,975	​	$ 2,107

See Note 6. Fair Value Measurements for information regarding fair value of derivative instruments.

As a result of using derivative financial instruments, we are exposed to the risk that counterparties to contracts could fail to meet their contractual obligations. We manage this credit risk by reviewing counterparty creditworthiness on a regular basis and limiting exposure to any single counterparty.

NOTE 8. ACCOUNTS AND OTHER RECEIVABLES, NET

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

​	​	​	​	​	​
​	​	June 30,		​	December 31,
​		2022			2021
Amounts billed, net	​	$	254,396	​	$ 217,549
Unbilled receivables	​	​	16,443	​	19,678
Total receivables, net	​	$	270,839	​	$ 237,227

"Amounts billed, net" represents amounts invoiced to customers in accordance with our terms and conditions and reflects an allowance for expected credit losses. These receivables are short term in nature and do not include any financing components.

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

The following table summarizes the changes in expected credit losses:

NOTE 16. STOCK-BASED COMPENSATION

As of June 30, 2022, we had two active stock-based incentive compensation plans: the 2017 Omnibus Incentive Plan ("the 2017 Plan") and the Employee Stock Purchase Plan ("ESPP"). We issue all new equity compensation grants under these two plans; however, outstanding awards previously issued under inactive plans will continue to vest and remain exercisable in accordance with the terms of the respective plans.

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

NOTE 17. COMMITMENTS AND CONTINGENCIES

We are involved in disputes and legal actions arising in the normal course of our business. While we currently believe that the amount of any ultimate loss would not be material to our financial position, the outcome of these actions is inherently difficult to predict. In the event of an adverse outcome, the ultimate loss could have a material adverse effect on our financial position or reported results of operations. An unfavorable decision in intellectual property litigation also could require material changes in production processes and products or result in our inability to ship products or components found to have violated third-party intellectual property rights. We accrue loss contingencies in connection with our commitments and contingencies, including litigation, when it is probable that a loss has occurred, and the amount of the loss can be reasonably estimated. We are not currently a party to any legal action that we believe would reasonably have a material adverse impact on its business, financial condition, results of operations or cash flows.

NOTE 18. CREDIT FACILITY

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

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

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

​	​	​	​	​	​	​	​
​		June 30, 2022
​	​	Balance			Interest Rate		Unused Line Fee
Term Loan Facility subject to a fixed interest rate	​	$	246,969	​	1.271 %	​	—
Term Loan Facility subject to a variable interest rate	​	​	138,031	​	2.416 %	​	—
Revolving Facility subject to a variable interest rate	​	​	—	​	2.416 %	​	0.10 %
Total borrowings under the Credit Agreement	​	$	385,000	​	​	​	​

For more information on the interest rate swap that fixes the interest rate for a portion of our Term Loan Facility, see Note 7. Derivative Financial Instruments . The Term Loan Facility and Revolving Facility bear interest, at our option, at a rate based on a reserve adjusted "Eurodollar Rate" or "Base Rate," as defined in the Credit Agreement, plus an applicable margin.

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

At the beginning of 2020 we saw the spread of COVID-19, which grew into a global pandemic. Our focus on providing a healthy and safe working environment for our employees led to intermittent shutdowns of our manufacturing facilities to implement new health and safety protocols and additional investments to comply with government guidelines. Since 2020, there have been periods when some of our manufacturing facilities were not operating or were operating at reduced capacity due to government mandates to restrict travel, maintain social distancing, and implement health and safety procedures. Additionally, during the first half of 2022, there were ongoing restrictions related to COVID-19 and disruptions in an already challenged global supply chain that disrupted our workforce and limited the availability of certain materials, parts, subcomponents, and subassemblies needed for production, which impacted our ability to fulfill product shipments to meet customer demand and contributed to increased backlog. The shortage of critical components was caused by a variety of factors including the pandemic-driven rise in consumer demand for technology goods, increased demand for electronic components used in a wide variety of industries, logistics-related disruptions in shipping, and capacity limitations at some suppliers due to COVID-19 and its variants, labor shortages, and other factors. We expect the challenges associated with this environment to continue for the remainder of 2022.

Although COVID-19 has impacted our revenues and manufacturing efficiency for the last two years, COVID-19 has not materially impacted our liquidity, our ability to access capital, our ability to comply with our debt covenants or the fair value of our assets. Additionally, we believe the accommodations we have made to our work environment, including employees utilizing work-from-home arrangements where necessary, will not impact our ability to maintain effective internal controls over financial reporting.

Looking forward, we expect that for the remainder of 2022 customer demand will remain strong across our served markets; however, our ability to procure critical components to meet our customers’ needs will continue to be limited by the ongoing constraints in the global supply chain. These supply constraints have led to longer lead times in procuring materials and subcomponents and, in some cases, higher costs and inventory level requirements. We have implemented measures to improve supply of critical materials and components and to mitigate the impact of these higher input costs, and these actions have enabled us to better meet customer demand. However, it is not clear how long this supply chain condition will continue, how quickly it may recover, the extent to which our mitigating actions will be successful, or to what extent we can recover our higher costs. In addition, recent increases in global inflation, interest rates, geopolitical tensions, and other factors impacting macroeconomic growth may impact future demand and our cost base. As such, our forward-looking projections of revenues, earnings, and cash flow may be adversely impacted if the supply chain constraint, COVID-19, or macroeconomic environment continues or further deteriorates .

For additional discussion on the potential impacts of COVID-19 to the future operations of our business, please see the information under the caption "Risk Factors" in Part II, in Item 1A of this Quarterly Report on Form 10-Q and Part I, Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2021 .

Semiconductor Equipment Market

Growth in the Semiconductor Equipment market is driven by growing integrated circuits content across many industries such as processing and storage in advanced applications including artificial intelligence, edge and cloud computing, autonomous vehicles, and the rapid adoption of advanced mobile connectivity solutions such as 5G, which enhances existing and enables new wireless applications. To address the long-term growing demand for semiconductor devices, the industry continues to invest in production capacities for both leading-edge and trailing-edge nodes, logic devices, the latest memory devices, back-end test, and advanced wafer-level packaging. The industry’s transition to advanced technology nodes in logic and DRAM and to increased layers in 3D NAND memory devices require an increased number of plasma-based etch and deposition process tools and higher content of our advanced power solutions per tool. As etching and deposition processes become more challenging due to increasing aspect ratios in advanced 3D devices, more advanced RF and direct current ("DC") plasma generation technologies are needed. We strive to meet 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 wafer fab, including inspection, metrology, thermal, ion implantation, and semiconductor test and assembly, where Advanced Energy is actively participating as a critical technology provider. In addition, our global support services group offers comprehensive local repair service, upgrade, and retrofit offerings to extend the useable life of our customers’ capital equipment for additional technology generations. Our strategy in the Semiconductor Equipment market is to defend our proprietary positions in our core applications, grow our market position in applications where we have lower share, including remote plasma source and dielectric etch, and leverage our product portfolio in areas such as embedded power, high voltage power system, and critical sensing and controls to grow our share and contents at our key original equipment manufacturer ("OEM") customers.

SALES AND BACKLOG

Total Sales

Sales increased $79.6 million, or 22.0%, to $440.9 million for the three months ended June 30, 2022 and $125.5 million, or 17.6%, to $838.4 million for the six months ended June 30, 2022 as compared to the same periods in the prior year.

The increase in sales was primarily due to growth in the overall Semiconductor Equipment market and measures we took to improve material availability and capacity, which allowed us to better meet the demand across our markets. During the three and six months ended June 30, 2022, the acquisition of SL Power Electronics Corporation ("SL Power") contributed $12.9 million to our total sales. For additional information, see Note 2. Acquisitions in Part I, Item 1 "Unaudited Consolidated Financial Statements."

Revenues in the first half of 2022 continued to be constrained relative to demand across all of our markets by supply chain shortages for certain integrated circuits and other components, which limited our ability to fulfill product shipments to meet our total demand. As a result, we saw an increase in backlog, as indicated in the table below.

Backlog

The following table summarizes our backlog (in thousands):

​	​	​	​	​	​	​	​	​	​	​	​	​	​	​	​	​
​		June 30,	​	December 31,		June 30,	​	Change from Year End			​	​	Change from Same Period One Year Ago			​
​		2022		2021		2021		Dollar		Percent	​		Dollar		Percent	​
Backlog	​	$ 1,166,490	​	$ 927,810	​	$ 534,707	​	$ 238,680	​	25.7	%	​	$ 631,783	​	118.2	%

Backlog represents outstanding orders for products we expect to deliver within the next 12 months. Backlog increased meaningfully from the end of last year and the same period one year ago due to the global supply constraint environment, resulting in customers placing larger orders than historical levels in anticipation of longer-term demand and our lead time extending. We believe these higher backlog levels provide some level of revenue protection if demand levels are reduced due to macroeconomic factors.

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

Sales by Market

Sales in the Semiconductor Equipment market increased $52.1 million, or 29.5%, to $228.8 million for the three months ended June 30, 2022 and $74.4 million, or 20.8%, to $431.8 million for the six months ended June 30, 2022 as compared to the same periods in the prior year. The increase in sales during 2022 is primarily due to growth in the semiconductor equipment market, improving parts availability, increases in factory output, market share gains in selected areas, and expansion of our product portfolio.

Sales in the Industrial and Medical market increased $21.8 million, or 26.1%, to $105.0 million for the three months ended June 30, 2022 and $26.2 million, or 16.2%, to $187.8 million for the six months ended June 30, 2022, as compared to the same periods in the prior year. The increase in sales relative to the same period in the prior year was primarily due to incremental sales from our acquisition of SL Power, improved material availability, and increased demand for our products.

Sales in the Data Center Computing market decreased $0.3 million, or 0.4%, to $69.2 million for the three months ended June 30, 2022 and increased $16.8 million, or 13.1%, to $145.4 million for the six months ended June 30, 2022 as compared to the same periods in the prior year. The increase in Data Center Computing market sales during the

32

Table of Contents

six months ended June 30, 2022 is due in part to the digestion of equipment at key accounts in early 2021 and better supply availability, which enabled us to partially fulfill product shipments against higher customer demand.

Sales in the Telecom and Networking market increased $6.1 million, or 18.9%, to $38.0 million for the three months ended June 30, 2022 and $8.1 million, or 12.4%, to $73.4 million for the six months ended June 30, 2022 as compared to the same periods in the prior year. The increase in sales was primarily due to improved material availability enabling us to better meet higher customer demand.

GROSS PROFIT

For the three months ended June 30, 2022, gross profit increased $27.1 million to $162.2 million, or 36.8% of revenue, as compared to $135.0 million, or 37.4% of revenue, in the same period in the prior year. For the six months ended June 30, 2022, gross profit increased $33.9 million to $306.5 million, or 36.6% of revenue, as compared to $272.5 million, or 38.2% of revenue, in the same period in the prior year. The decrease in gross profit as a percent of revenue is largely related to higher material and freight costs. Additional drivers of our decrease in gross profit as a percentage of sales include productivity inefficiencies resulting from supply constraints, COVID-19 capacity restrictions, and the transition of our Shenzhen, People’s Republic of China manufacturing to Penang, Malaysia. These factors were partly offset by increased volume and favorable product mix.

OPERATING EXPENSE

Research and Development

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

Research and development expenses increased $7.9 million to $48.0 million for the three months ended June 30, 2022 and increased $11.3 million to $91.6 million for the six months ended June 30, 2022 as compared to the same periods in the prior year. The increase in research and development expense is related to the acquisition of SL Power, increased headcount and associated costs, outside technical services, and engineering materials 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 $6.9 million to $55.0 million for the three months ended June 30, 2022 and increased $9.5 million to $104.3 million for the six months ended June 30, 2022 as compared to the same periods in the prior year. The increase in SG&A is principally related to acquisition related activities, sales commissions driven by higher revenue, an increase in headcount, and an increase in variable compensation.

Amortization of Intangibles

Amortization expense increased $1.0 million to $6.5 million during the three months ended June 30, 2022 and increased $1.1 million to $12.0 million for the six months ended June 30, 2022, as compared to the same periods in the prior year. The increase is primarily driven by incremental amortization of newly acquired intangible assets. For

33

Table of Contents

additional information, see Note 2. Acquisitions and Note 12. Intangible Assets in Part I, Item 1 "Unaudited Consolidated Financial Statements."

Restructuring

Restructuring charges relate to previously announced management plans to optimize our manufacturing footprint to lower cost regions, improvements in operating efficiencies, and synergies related to acquisitions. For additional information, see Note 13. Restructuring Costs in Part I, Item 1 "Unaudited Consolidated Financial Statements."

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 increased $6.9 million to $3.2 million for the three months ended June 30, 2022 and increased $6.6 million to $2.4 million for the six months ended June 30, 2022 as compared to the same periods in the prior year. The increase in income between periods is primarily a result of higher unrealized foreign exchange gains due to the strengthening US dollar compared to our other foreign currencies. This was partially offset by higher interest expense on increasing interest rates.

PROVISION FOR INCOME TAXES

The following table summarizes tax expense (in thousands) and the effective tax rate for our income from continuing operations:

​	​	​	​	​	​	​	​	​	​	​	​	​	​
​	​	Three Months Ended June 30,					​	Six Months Ended June 30,					​
​		2022			2021			2022			2021		​
Income from continuing operations, before income taxes	​	$	56,014	​	$	37,418	​	$	99,829	​	$	81,093	​
Provision for income taxes	​	$	11,203	​	$	1,876	​	$	18,156	​	$	7,160	​
Effective tax rate	​	​	20.0	%	​	5.0	%	​	18.2	%	​	8.8	%

Our effective tax rates differ from the U.S. federal statutory rate of 21% for the three and six months ended June 30, 2022 and 2021, respectively, primarily due to the benefit of earnings in foreign jurisdictions which are subject to lower tax rates, as well as tax credits, partially offset by net U.S. tax on foreign operations. The effective tax rate for both the three and six months ended June 30, 2022 was higher than the same periods in 2021 primarily driven by the global impact to our provision from capitalizing and amortizing research and development expenses rather than immediately expensing them starting in 2022 as required by the 2017 Tax Cuts and Jobs Act. Congress has proposed tax legislation to delay the effective date of this change, but it is uncertain whether the proposed delay will ultimately be enacted into law. Additionally, there were beneficial discrete events in 2021 that did not recur in 2022.

Our future effective income tax rate depends on various factors, such as changes in tax laws, regulations, accounting principles, or interpretations thereof, and the geographic composition of our pre-tax income. We carefully monitor these factors and adjust our effective income tax rate accordingly.

Non-GAAP Results

Management uses non-GAAP operating income and non-GAAP earnings per share ("EPS") to evaluate business performance without the impacts of certain non-cash charges and other charges which are not part of our usual operations. We use these non-GAAP measures to assess performance against business objectives, make business decisions, including developing budgets and forecasting future periods. In addition, management’s incentive plans include these non-GAAP measures as criteria for achievements. These non-GAAP measures are not in accordance with U.S. GAAP and may differ from non-GAAP methods of accounting and reporting used by other companies. However, we believe these non-GAAP measures provide additional information that enables readers to evaluate our business from the perspective of management. The presentation of this additional information should not be considered a substitute for results prepared in accordance with U.S. GAAP.

Table of Contents

The non-GAAP results presented below exclude the impact of non-cash related charges, such as stock-based compensation, amortization of intangible assets, and non-economic foreign exchange gains/losses. In addition, they exclude discontinued operations and other non-recurring items such as acquisition-related costs and restructuring expenses, as they are not indicative of future performance. The tax effect of our non-GAAP adjustments represents the anticipated annual tax rate applied to each non-GAAP adjustment after consideration of their respective book and tax treatments and effect of adoption of the 2017 Tax Cuts and Jobs Act.

Impact of Inflation

In previous years, inflation has not had a significant impact on our operations. However, more recently we are experiencing inflationary pressure from price increases in select components driven by factors such as higher global demand, supply chain disruptions, higher labor expenses, and increased freight costs. In this environment, we are actively working with our customers to adjust pricing that helps offset the inflationary pressure on the cost of our components.

Liquidity and Capital Resources

Liquidity

We believe that adequate liquidity and cash generation is important to the execution of our strategic initiatives. Our ability to fund our operations, acquisitions, capital expenditures, and product development efforts may depend on our ability to generate cash from operating activities which is subject to future operating performance, as well as general economic, financial, competitive, legislative, regulatory, and other conditions, some of which may be beyond our control. Our primary sources of liquidity are our available cash, investments, cash generated from current operations, and available borrowing capacity under the Revolving Facility (defined in Note 18. Credit Facility in Part I, Item 1 "Unaudited Consolidated Financial Statements").

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

​	​	​
​	​	June 30, 2022
Cash and cash equivalents	​	$ 372,685
Marketable securities	​	2,162
Total cash, cash equivalents, and marketable securities	​	$ 374,847

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

Credit Facility

For information on our Credit Facility, see Note 18. Credit Facility and Note 7. Derivative Financial Instruments in Part I, Item 1 "Unaudited Consolidated Financial Statements."

The following table summarizes borrowings under our Credit Facility and the associated interest rate (in thousands, except for interest rates).

​	​	​	​	​	​	​	​
​		June 30, 2022
​	​	Balance			Interest Rate		Unused Line Fee
Term Loan Facility subject to a fixed interest rate	​	$	246,969	​	1.271%	​	—
Term Loan Facility subject to a variable interest rate	​	​	138,031	​	2.416%	​	—
Revolving Facility subject to a variable interest rate	​	​	—	​	2.416%	​	0.10%
Total borrowings under the Credit Agreement	​	$	385,000	​	​	​	​

As of June 30, 2022, we had $200.0 million in available funding under the Revolving Facility. The Term Loan Facility requires quarterly repayments of $5.0 million plus accrued interest, with the remaining balance due in September 2026.

In addition to the available capacity on the Revolving Facility, prior to the maturity date of our Credit Agreement, we may also request an increase to the financing commitments in either the Term Loan Facility or Revolving Facility by an aggregate amount not to exceed $250.0 million at identical terms to our existing Credit Facility.

Table of Contents

Dividends

In March 2021, the Board of Directors (the "Board") declared the first quarterly cash dividend since our inception as a public company. During the six months ended June 30, 2022, we paid quarterly cash dividends of $0.10 per share totaling $7.6 million. We currently anticipate that a cash dividend of $0.10 per share will continue to be paid on a quarterly basis, although the declaration of any future cash dividend is at the discretion of the Board and will depend on our financial condition, results of operations, capital requirements, business conditions, and other factors.

Share Repurchase

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

​	​	​	​	​	​	​	​	​	​
​	​	Three Months Ended June 30,			​	Six Months Ended June 30,			​
(in thousands, except per share amounts)		2022		2021		2022		2021	​
Amount paid or accrued to repurchase shares	​	$ 17,019	​	$ 6,503	​	$ 23,613	​	$ 6,503	​
Number of shares repurchased	​	230	​	72	​	312	​	72	​
Average repurchase price per share	​	$ 74.12	​	$ 90.34	​	$ 75.68	​	$ 90.34	​

At June 30, 2022, the remaining amount authorized by the Board of Directors for future share repurchases was $104.8 million. In July 2022, the Board of Directors approved an increase to the share repurchase plan that changed the remaining amount authorized for future repurchases to a maximum of $200.0 million with no time limitation.

Cash Flows

A summary of our cash from operating, investing, and financing activities is as follows (in thousands):

​	​	​	​	​	​
​	​	Six Months Ended June 30,			​
​		2022		2021	​
Net cash from operating activities from continuing operations	​	$ 47,541	​	$ 88,066	​

Cash and cash equivalents, end of period	​	$ 372,685	​	$ 507,176	​

Net Cash From Operating Activities

Net cash from operating activities from continuing operations for the six months ended June 30, 2022, was $47.5 million, as compared to $88.1 million for the same period in the prior year. The decrease of $40.6 million in net cash flows from operating activities as compared to the same period in the prior year is due to an unfavorable increase in net operating assets driven primarily by our increased investment in inventory as we attempted to mitigate supply chain constraints.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires us to make judgments, assumptions and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Note 1. Operation and Summary of Significant Accounting Policies and Estimates to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2021, describes the significant accounting policies and methods used in the preparation of our consolidated financial statements. Our critical accounting estimates, discussed in the "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2021, include:

● estimates for the valuation of assets and liabilities acquired in business combinations;

● accounting for income taxes;

● inputs to actuarial models that measure our pension obligations; and

● assessing excess and obsolete inventories.

Such accounting policies and estimates require significant judgments and assumptions to be used in the preparation of the consolidated financial statements and actual results could differ materially from the amounts reported based on variability in factors affecting these estimates.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk and Risk Management

In the normal course of business, we have exposures to interest rate risk from our investments and credit facility. We have exposure to foreign exchange rate risk related to our foreign operations and foreign currency transactions.

See the "Risk Factors" set forth in Part I, Item 1A of our Annual Report on Form 10-K and Part II, Item 1A of this Form 10-Q for more information about the market risks to which we are exposed. There have been no material changes in our exposure to market risk from December 31, 2021.

Foreign Currency Exchange Rate Risk

We are impacted by changes in foreign currency exchange rates through sales and purchasing transactions when we sell products and purchase materials in currencies different from the currency in which product and manufacturing costs were incurred.

Our reported financial results of operations, including the reported value of our assets and liabilities, are also impacted by changes in foreign currency exchange rates. Assets and liabilities of substantially all our subsidiaries outside the U.S. are translated at period end rates of exchange for each reporting period. Operating results and cash flow statements are translated at average rates of exchange during each reporting period. Although these translation changes have no immediate cash impact, the translation changes may impact future borrowing capacity, and overall value of our net assets.

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

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.

39

Table of Contents

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

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

From time to time, we may enter into foreign currency exchange rate contracts to hedge against changes in foreign currency exchange rates on assets and liabilities expected to be settled at a future date, including foreign currency, which may be required for a potential foreign acquisition. Market risk arises from the potential adverse effects on the value of derivative instruments that result from a change in foreign currency exchange rates. We may enter into foreign currency forward contracts to manage the exchange rate risk associated with intercompany debt denominated in nonfunctional currencies. We minimize our market risk applicable to foreign currency exchange rate contracts by establishing and monitoring parameters that limit the types and degree of our derivative contract instruments. We enter into derivative contract instruments for risk management purposes only. We do not enter into or issue derivatives for trading or speculative purposes.

Interest Rate Risk

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

​	​	​	​	​	​	​	​
​		June 30, 2022
​	​	Balance			Interest Rate		Unused Line Fee
Term Loan Facility subject to a fixed interest rate	​	$	246,969	​	1.271%	​	—
Term Loan Facility subject to a variable interest rate	​	​	138,031	​	2.416%	​	—
Revolving Facility subject to a variable interest rate	​	​	—	​	2.416%	​	0.10%
Total borrowings under the Credit Agreement	​	$	385,000	​	​	​	​

For more information on the Term Loan Facility see Note 18. Credit Facility in Part I, Item 1 "Unaudited Consolidated Financial Statements." For more information on the interest rate swap that fixes the interest rate for a portion of our Term Loan Facility, see Note 7. Derivative Financial Instruments in Part I, Item 1 "Unaudited Consolidated Financial Statements." The Term Loan Facility and Revolving Facility bear interest, at our option, at a rate based on a reserve adjusted "Eurodollar Rate" or "Base Rate," as defined in the Credit Agreement, plus an applicable margin.

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

ITEM 4. 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 ("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 (Stephen D. Kelley, President and Chief Executive Officer) and Principal Financial Officer (Paul Oldham, Chief Financial Officer), as appropriate, to allow timely decisions regarding required disclosures.

As of the end of the period covered by this report, we conducted an evaluation, with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures pursuant to the Exchange Act Rule 13a-15(b). Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2022. 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 over financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the quarter covered by this Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are involved in disputes and legal actions arising in the normal course of our business. Although it is not possible to predict the outcome of these matters, we believe that the results of these proceedings will not have a material adverse effect on our financial condition, results of operations, or liquidity.

ITEM 1A. RISK FACTORS

Information concerning our risk factors is contained in Part I, Item 1A, “Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2021. The risks described in our Annual Report on Form 10-K are not the only risks that we face; additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, or operating results. There have been no material changes to the risk factors previously disclosed in our Annual Report on Form 10-K.
