NOTE 1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

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 this raw power into various types of highly controllable, usable power that is predictable, repeatable, and customizable to meet the necessary requirements for powering a wide range of complex equipment. Many of our products enable our original equipment manufacturer (“OEM”) customers to optimize their energy consumption through increased power conversion efficiency, power density, power coupling, and process control across a wide range of applications.

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

In management's opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal, recurring adjustments, necessary to present fairly Advanced Energy’s financial position as of September 30, 2023, and the results of our operations and cash flows for the three and nine months ended September 30, 2023 and 2022.

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, 2022 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 ● income tax 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, 2022.

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 Acco unting Standards Adopted

The FASB issued the following ASUs that we adopted in the current year:

​

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

​

This collective guidance provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria that reference LIBOR or another reference rate that is expected to be discontinued.

Our Credit Agreement (see Note 18. Long-Term Debt) and interest rate swap agreements (see Note 7. Derivative Financial Instruments) referenced the one-month USD LIBOR rate. On March 31, 2023, we executed agreements with our debt holders and the counterparties to our interest rate swap agreements to transition the benchmark interest rate from LIBOR to the one-month-USD Term Secured Overnight Financing Rate (“SOFR”). The impact of this transition and the adoption of the above guidance was not material to our consolidated financial statements.

NOTE 2. ACQUISITIONS

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

The components of the fair value of the total consideration transferred were as follows:

​

​ | ​ | ​ | ​
Cash paid for acquisition | ​ | $ | 145,693
Less cash acquired | ​ | ​ | (3,484)
Total fair value of purchase consideration | ​ | $ | 142,209

​

We allocated the purchase price consideration to the assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date, with the excess allocated to goodwill.

​

​ | ​ | ​ | ​
​ | ​ | Fair Value
Current assets and liabilities, net | ​ | $ | 12,329
Property and equipment | ​ | ​ | 3,567
Operating lease right-of-use assets | ​ | ​ | 4,640
Deferred tax and other liabilities | ​ | ​ | (2,326)
Intangible assets | ​ | ​ | 57,600
Goodwill | ​ | ​ | 71,039
Operating lease liability | ​ | ​ | (4,640)
Total fair value of net assets acquired | ​ | $ | 142,209

​

The following table summarizes the intangible assets acquired:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | ​ | ​ |  | Amortization |  | Useful Life
​ | ​ | Fair Value | ​ | Method | ​ | (in years)
Customer relationships | ​ | $ | 50,500 |  | Straight-line |  | 10
Technology | ​ |  | 7,100 |  | Straight-line |  | 5
Total | ​ | $ | 57,600 |  |  |  |

​

To estimate the fair value of intangible assets, we used a multi-period excess earnings approach for the customer relationships and a relief from royalty approach for developed technology. Goodwill represents SL Power’s assembled workforce and the expected operating synergies from combining operations. We expect virtually all of the goodwill to be deductible for tax purposes.

NOTE 4. INCOME TAX

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

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended September 30, | ​ | Nine Months Ended September 30, | ​
​ |  | 2023 |  | 2022 |  | 2023 |  | 2022 | ​
Income from continuing operations, before income tax | ​ | $ | 34,525 | ​ | $ | 86,512 | ​ | $ | 106,263 | ​ | $ | 186,341 | ​
Provision for income tax | ​ | $ | 874 | ​ | $ | 11,639 | ​ | $ | 13,405 | ​ | $ | 29,795 | ​
Effective tax rate | ​ | ​ | 2.5% | ​ | ​ | 13.5% | ​ | ​ | 12.6% | ​ | ​ | 16.0% | ​

​

Our effective tax rates differ from the U.S. federal statutory rate of 21% for the three and nine months ended September 30, 2023 and 2022, 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 the three and nine months ended September 30, 2023 was lower than the same periods in 2022 primarily due to the greater impact of beneficial discrete items primarily related to tax strategies we implemented in the three months ended September 30, 2023 relative to the beneficial discrete items recorded in the three months ended September 30, 2022.

​

We compute basic earnings per share of common stock (“Basic EPS”) by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period.

See Note 18. Long-Term Debt for information regarding our Convertible Notes, Note Hedges, and Warrants. For diluted earnings per share of common stock (“Diluted EPS”), we increase the weighted-average number of common shares outstanding during the period, as needed, to include the following:

| ● | Dilutive impact associated with the Convertible Notes using the if-converted method. The Convertible Notes are repayable in cash up to par value and in cash or shares of common stock for the excess over par value. Prior to conversion, we do not consider the Note Hedges for purposes of Diluted EPS as their effect would be anti-dilutive. Upon conversion, we expect the Note Hedges to offset the dilutive effect of the Convertible Notes when the stock price is above $137.46;

| ● | Additional common shares that would have been outstanding if our outstanding stock awards had been converted to common shares using the treasury stock method. We exclude any stock awards that have an anti-dilutive effect; and

| ● | Dilutive effect of the Warrants issued concurrently with the Convertible Notes using the treasury stock method. For all periods presented, the Warrants did not increase the weighted-average number of common shares outstanding because the exercise price of the Warrants exceeded the average market price of our common stock.

Share Repurchase

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

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended September 30, | ​ | Nine Months Ended September 30,

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

At September 30, 2023, the remaining amount authorized by the Board of Directors (“the Board”) for future share repurchases was $199.3 million with no time limitation.

NOTE 7. DERIVATIVE FINANCIAL INSTRUMENTS

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

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

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | September 30, | ​ | December 31,
​ |  | 2023 |  | 2022
Foreign currency forward contracts | ​ | $ | 104,137 | ​ | $ | —

​

Gains and losses related to foreign currency exchange contracts were offset by corresponding gains and losses on the revaluation of the underlying assets and liabilities. Both are included as a component of other income (expense), 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, see Note 18. Long-Term Debt). On March 31, 2023, we executed agreements with our debt holders and the counterparties to our interest rate swap agreements to transition the benchmark interest rate from LIBOR to SOFR. The interest rate swap contracts expire on September 10, 2024 and are accounted for as cash flow hedging instruments.

(In thousands, except per share data)

​

The interest rate swap contracts fix a portion of the outstanding principal balance on our Term Loan Facility to a total interest rate of 1.172%. This is comprised of a 0.322% average fixed rate per annum in exchange for a variable interest rate based on SOFR plus the credit spread in our existing Credit Agreement (see Note 18. Long-Term Debt), which is 75 basis points at current leverage ratios plus a LIBOR to SOFR transitional rate adjustment of 0.10%.

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

Interest rate swap contracts | ​ | $ | 225,094 | ​ | $ | 238,219

Interest rate swap contract gains | ​ | $ | 7,885 | ​ | $ | 11,779

​

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 13. RESTRUCTURING COSTS

In the fourth quarter of 2022, we approved a restructuring plan (the “2022 Plan”), which is expected to further improve our operating efficiencies and drive the realization of synergies from our business combinations by consolidating our operations, optimizing our factory footprint, including moving certain production into our higher volume factories, reducing redundancies, and lowering our cost structure. The majority of these actions impact our factory operations and should partially mitigate the impact of lower volumes on gross margins. Although we expect additional charges under this plan as we refine and execute our actions, we anticipate the 2022 Plan will be substantially completed, and associated expenses will be incurred, by the end of 2024.

​

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

The tables below summarize the charges related to our restructuring plans:

NOTE 16. STOCK-BASED COMPENSATION

The Compensation Committee of our Board administers our stock plans. As of September 30, 2023, we have two active stock-based incentive compensation plans: the 2023 Omnibus Incentive Plan (“the 2023 Plan”) and the Employee Stock Purchase Plan (“ESPP”). The 2023 Plan was approved on April 27, 2023. 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.

The 2023 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, stock units, unrestricted stock, and dividend equivalent rights. Any of the awards issued may be issued as performance-based awards to align stock compensation awards to the attainment of annual or long-term performance goals.

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

​

​ | ​ | ​
​ | ​ | September 30, 2023
Shares available for future issuance under the 2023 Plan | ​ | 2,318
Shares available for future issuance under the ESPP | ​ | 598

​

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

Generally, we grant stock option awards with an exercise price equal to the market price of our stock at the date of grant and with either a three or four-year vesting schedule or performance-based vesting. Stock option awards generally have a term of ten years.

We recognize stock-based compensation expense based on the fair value of the awards issued and the functional area of the employee receiving the award. Stock-based compensation was as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

NOTE 17. COMMITMENTS AND CONTINGENCIES

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

Convertible Senior Notes due 2028

On September 12, 2023, we completed a private, unregistered offering of $575.0 million aggregate principal amount 2.50% convertible senior notes (“Convertible Notes”) and received net proceeds of approximately $562.1 million after the discount for the initial purchasers’ fees. We used $40.0 million of the net proceeds to repurchase approximately 0.4 million shares of common stock and $40.1 million to fund the net cost of convertible note hedge transactions (“Note Hedges”) (after such costs were offset by the proceeds from the sale of warrants to purchase our common stock (“Warrants”).

The Convertible Notes mature on September 15, 2028, unless earlier repurchased, redeemed, or converted. Interest is payable semi-annually in arrears in March and September. We do not maintain a sinking fund.

We may redeem for cash all or any portion of the Convertible Notes, at our option, on or after September 20, 2026 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading-day period (including the last trading day of such period). The redemption price is 100% of the principal amount plus accrued and unpaid interest.

Prior to May 15, 2028, holders have the option to convert all or a portion of their Convertible Notes under the following circumstances:

| ● | during any calendar quarter if the last reported sale price of our common stock, for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days is greater than or equal to 130% of the conversion price on each applicable trading day;

| ● | during the five business day period immediately after any five consecutive trading day period in which the trading price per $1,000 principal amount of the Convertible Notes for each trading day was less than 98% of the product of the last reported sale price of our common stock on each such trading day and the conversion rate on each such trading day;

| ● | if Advanced Energy calls any or all of the Convertible Notes for redemption; or

| ● | upon the occurrence of specified corporate transactions or events described in the indenture.

From May 15, 2028 through the maturity date, holders have the option to convert at any time regardless of circumstances.

The initial conversion rate is 7.2747 shares of common stock per $1,000 principal amount, which is equivalent to an initial conversion price of approximately $137.46 per share of common stock. The conversion rate is subject to adjustment upon the occurrence of certain specified events as set forth in the indenture.

Upon conversion, Advanced Energy will do the following:

| ● | pay cash up to the aggregate principal amount to be converted; and

| ● | pay or deliver cash, shares of our common stock, or a combination (at our election) with respect to the remainder, if any, of the conversion obligation in excess of the aggregate principal amount being converted.

Concurrent with the Convertible Notes issuance, we entered into the Note Hedges with respect to our common stock. We will exercise the Note Hedges simultaneously when the Convertible Notes are settled. The Note Hedges have a $137.46 per share initial exercise price and cover, subject to customary anti-dilution adjustments, the number of shares of common stock that initially underlie the Convertible Notes and are expected to reduce the potential dilution to the common stock and/or offset potential cash payments in excess of the principal amount upon conversion of

​

the Convertible Notes. We paid approximately $115.0 million in cash for the Note Hedges, which we recorded to additional paid-in capital in our Statements of Stockholders’ Equity.

Also concurrent with the issuance of our Convertible Notes, we sold Warrants, which provide the counterparties the option to acquire approximately 4.2 million aggregate shares of our common stock (subject to customary anti-dilution adjustments), which is the same number of shares of our common stock covered by the Note Hedges at a $179.76 per share initial exercise price, which represents a 70% premium over the $105.74 closing price of our common stock on September 7, 2023. The Warrants expire on July 7, 2029. We received aggregate proceeds of $74.9 million for the sale of Warrants, which we recorded to additional paid-in capital in our Statements of Stockholders’ Equity.

If the market value per share of our common stock exceeds the exercise price of the Warrants during the measurement period at the maturity of such Warrants, the Warrants will have a dilutive effect on our earnings per share as we will owe the counterparties a number of shares of common stock in an amount based on the excess of such market price per share of the common stock over the Warrants’ exercise price.

The Note Hedge and Warrants are separate from the Convertible Notes. The Convertible Notes holders have no rights with respect to the Note Hedges and Warrants. Counterparties in the Note Hedge and Warrants transactions have no rights with respect to the Convertible Notes. However, in combination, the Note Hedges and Warrants synthetically increase the initial conversion price on the Convertible Notes from $137.46 to $179.76, reducing the potential dilutive effect of the Convertible Notes.

We recorded a $26.1 million deferred tax asset to reflect the impact of the Convertible Notes and Note Hedges.

Credit Agreement

Our credit agreement dated as of September 10, 2019, as amended (the “Credit Agreement”) consists of a senior unsecured term loan facility (“Term Loan Facility”) and a senior unsecured revolving facility (“Revolving Facility”). Both mature on September 9, 2026.

On March 31, 2023, we executed agreements pursuant to the Credit Agreement to transition the benchmark interest rate from LIBOR to SOFR. The impact of this transition was not material to our consolidated financial statements.

On September 7, 2023, we entered into an additional amendment to the Credit Agreement to amend certain definitions, covenants, and events of default to enable the issuance of the Convertible Notes and the entry into the Note Hedges and Warrants.

The following table summarizes our availability to withdraw on the Revolving Facility:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | September 30, | ​ | December 31,
​ |  | 2023 |  | 2022
Available capacity on Revolving Facility | ​ | $ | 200,000 | ​ | $ | 200,000

​

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 $115.0 million.

We use level 2 measurements to estimate the fair value of our debt. As of September 30, 2023, the outstanding principal balance on our Term Loan Facility approximates fair value, and we estimate the fair value of our Convertible Notes to be $575.0 million.

The demand environment in each of our markets is impacted by various market trends, customer buying patterns, design wins, macroeconomic conditions, and other factors. Since the fourth quarter of 2022, demand in some of our markets began to decline, most notably due to the semiconductor cyclical downturn and reduced investments in the Data Center Computing market. Subsequently, in the third quarter of 2023, demand in the Industrial and Medical market started to moderate due to macroeconomic conditions, and in this market, our ability to fulfill demand continues to be partially limited by ongoing supply constraints for some materials and components. We were constrained by supply chain shortages for critical integrated circuits, resulting in longer lead times for our products in 2022. Some of these supply constraints continued into 2023. We implemented measures to improve the supply of critical materials and components and to mitigate the impact of these higher input costs, and these actions have enabled us to better meet customer demand. Due to improved component supply, lead times for our products declined, which resulted in our 12-month backlog normalizing from $875.3 million at the end of 2022 to $514.5 million at the end of the third quarter of 2023.

Semiconductor Equipment Market

The Semiconductor Equipment market is driven by the long-term growing need for more semiconductor production capacity and new process technologies to meet increasing demand for integrated circuits that enable processing, storing, and transmitting a growing amount of data across many industries. To meet this demand, the chip industry continues to invest in production capacity for both leading-edge and trailing-edge nodes, logic devices, the latest memory devices, back-end test, and advanced wafer-level packaging. The industry’s transition to advanced technology nodes and to increased layers in memory devices requires an increased number of plasma-based etch and deposition process tools and higher content of our advanced power solutions per tool. Advanced Energy is a critical technology leader in the industry and provides one of the industry’s broadest portfolios of power conversion and related products, including plasma power, high-voltage power, and adjacent sensing solutions, to semiconductor capital equipment OEMs targeting a wide range of process technologies and device types. Our strategy in this market is to defend our proprietary positions in our core applications by capturing new design and product generations, grow our market position in applications where we have lower market share, such as remote plasma source and dielectric etch, and leverage our broad product portfolio in areas such as high and low voltage embedded power products to grow our market share and content at our OEM customers.

The Semiconductor Equipment market experienced demand growth driven by investments in both leading and trailing edge semiconductor capacity throughout the first three quarters of 2022. Starting in the fourth quarter of 2022, the market entered a downturn due to deteriorating macroeconomic conditions, overcapacity in the market for memory devices, prolonged weakness in demand for consumer electronics, such as smartphone, impacting leading-edge wafer capacity investments plans, general semiconductor inventory digestion resulting in falling fab utilization, and new U.S. export restrictions to China for certain semiconductor equipment. During the first nine months of 2023, these factors continued to impact our revenue, and they are expected to continue in the fourth quarter of 2023 and into 2024. We believe long-term drivers for demand growth in this market will eventually resume, due to the need to invest in new fab capacity to support growing demand for semiconductor devices in a wide range of applications, the continued transition to next generation processing nodes, increased complexity of advanced processes requiring more complex and innovative power solutions, and the regionalization of some semiconductor capacity.

Industrial and Medical Market

Advanced Energy serves the Industrial and Medical market with mission-critical, precision power products and solutions that deliver precise and highly reliable, low noise or differentiated power to OEM equipment. We also supply sensing, control, and instrumentation products to complement our power solutions. Growth in the Industrial and Medical market is driven by investment in complex manufacturing processes or automation, increased adoption of smart power, sensing, and control solutions across many industrial applications, new investments in clean and sustainable technologies, and growing investment in medical devices and life science equipment. Our customers are primarily global and regional OEMs that incorporate our solutions into a wide variety of applications, such as advanced material fabrication, medical devices, analytical instrumentation, test and measurement equipment, robotics, industrial production, and large-scale connected light-emitting diode applications. We serve this diverse market through both our direct sales force and indirect sales channels including independent sales representatives, channel partners, and distributors. Our strategy in the market is to expand our product offerings and channel reach, leveraging common platforms, derivatives, and customizations to further penetrate a broader set of applications.

During 2022, we saw increased demand in the Industrial and Medical market as our customers increased investments in their production capacity and the medical technology industry recovered from the pandemic-related slowdown. Although overall customer demand increased, supply constraints on critical components limited our ability to fulfill product shipments at the level of customer demand and resulted in increased backlog. During the first nine months of 2023, we secured critical components, enabling us to deliver record revenues in the first nine months in this market. However, in the third quarter of 2023 we began to see lower demand in this market due largely to macroeconomic factors and normalization of backlog levels. It is unclear how the macroeconomic conditions, including higher interest rates impacting end customer’s capital investment and potential recession, may affect customer demand and our revenue in the remainder of 2023 and into 2024. In addition, although the supply of critical components has improved, we continue to see some shortages and product delivery, and revenue levels in this market will continue to be partially dependent on our ability to secure supplies of critical components. Long-term, we continue to believe the diverse Industrial and Medical market offers many growth opportunities, and we plan to continue our investments to grow revenue in this market.

Data Center Computing Market

Advanced Energy serves the Data Center Computing market with industry-leading power conversion products and technologies, which we sell to OEMs and original design manufacturers of data center server and storage systems, as well as cloud service providers and their partners. Driven by the growing adoption of cloud computing and increasing demand for edge applications, the server and storage market is shifting from traditional enterprise on-premises computing to the data center. In addition, the rapid growth and adoption of artificial intelligence and machine learning are driving increased demand for substantially higher power server racks requiring increased power density and higher efficiency in server power supplies and accelerating the transition from 12 Volt to 48 Volt infrastructure in data center server racks. Advanced Energy benefits from these trends as an industry leader in providing high-efficiency, high-density, 48 Volt server power solutions to data center infrastructure customers. Our strategy in the market is to penetrate selected customers and applications based on our differentiated capabilities and competitive strengths in power density, efficiency, and controls.

In the first half of 2023, we saw reduced revenues due to slowing demand in the enterprise server and storage market as customers delayed investments. In addition, ongoing supply constraints limited our ability to meet the full demand. However, improved supply of critical components and demand for high end computing applications from some customers led to increased revenue in the third quarter of 2023 from the lower levels in first half of 2023. It is not clear how quickly our enterprise server and storage customers will return to their historical level of investments.

29

Table of Contents

Telecom and Networking Market

Advanced Energy’s customers in the Telecom and Networking market include many leading OEMs of wireless infrastructure equipment, telecommunication equipment and computer networking equipment. Growth in the market is driven by adoption of more advanced mobile standards, including 5G technologies which enable new advanced applications such as autonomous vehicles and virtual/augmented reality. In datacom, demand is driven by networking investments by telecom service providers and enterprises upgrading their networks, as well as cloud service providers and data centers investing in their networks for increased bandwidth. Our strategy in the market is to optimize our portfolio of power conversion products to more differentiated applications, and to focus on 5G infrastructure applications.

During the first nine months of 2023, substantially improved supply of critical components allowed us to largely fulfill outstanding demand from the prior year and drive strong revenue growth in the Telecom and Networking market as compared to the first nine months of 2022. However, leading companies in this market have reported end user weakness, and we do not expect to sustain the revenue levels of the first nine months of 2023 in the fourth quarter of 2023 and into 2024.

SALES AND BACKLOG

Total Sales

Sales decreased $106.3 million, or 20.6%, to $410.0 million for the three months ended September 30, 2023 and decreased $104.1 million, or 7.7%, to $1,250.5 million for the nine months ended September 30, 2023 as compared to the same periods in the prior year.

Revenues in three months ended September 30, 2023 declined from the same period in the prior year mainly due to the impact of market downturns in all of our markets, particularly the Semiconductor Equipment and Data Center Computing markets. Revenues in the first nine months of 2023 were also impacted by Semiconductor Equipment and Data Center Computing market downturns, but revenues in the Industrial and Medical and the Telecom and Networking markets increased as compared to the same periods in the prior year due to improved supply of certain components.

Backlog

The following table summarizes our backlog (in thousands):

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | September 30, | ​ | December 31, | ​ | Change from Year End | ​
​ |  | 2023 |  | 2022 | ​ | Dollar |  | Percent | ​
Backlog | ​ | $ | 514,471 | ​ | $ | 875,346 | ​ | $ | (360,875) | ​ | (41.2) | %

​

Backlog represents outstanding orders for products we expect to deliver within the next 12 months. Backlog at September 30, 2023 decreased from the end of 2022 due primarily to lower demand in some of our markets and improved lead times, which allowed our customers to reduce placing new orders for products with targeted deliveries in the later part of the 12-month backlog period.

We believe the current backlog levels provide some level of revenue protection should demand continue to decrease due to macroeconomic factors. We continue to expect backlog to return to a more normalized range of $400 million to $500 million.

Backlog at any particular date is not necessarily indicative of actual sales which may be generated for any succeeding period and may be adversely impacted by factors such as decreased demand, cancellations, or export controls. Our customers can typically cancel, change, or delay product purchase commitments with little or no notice.

Sales by Market

Sales in the Semiconductor Equipment market decreased $81.6 million, or 30.6%, to $185.0 million for the three months ended September 30, 2023 and $145.9 million, or 20.9%, to $552.4 million for the nine months ended September 30, 2023 as compared to the same periods in the prior year. The decrease in sales compared to the same periods in the prior year was primarily due to a cyclical downturn in the semiconductor industry and the U.S. export controls restricting shipments of equipment to Chinese semiconductor customers. The revenue decline in the first nine months was partially mitigated by strong service revenues and growth in certain applications, such as high voltage power supplies.

Sales in the Industrial and Medical market decreased $4.4 million, or 3.6%, to $115.2 million for the three months ended September 30, 2023 as compared to same period in the prior year. Sales increased $58.4 million, or 19.0%, to $365.8 million for the nine months ended September 30, 2023 as compared to the same period in the prior year. The decrease in sales for the three month period was primarily related to softer macroeconomic conditions in the third quarter of 2023. The increase in sales for the nine month period was primarily due to relatively stable demand for our portfolio of products across several industrial and medical applications and improved material availability.

Table of Contents

Sales in the Data Center Computing market decreased $19.3 million, or 22.0%, to $68.3 million for the three months ended September 30, 2023 and $45.9 million, or 19.7%, to $187.0 million for the nine months ended September 30, 2023 as compared to the same periods in the prior year. The decrease in Data Center Computing market sales was due to the cyclical downturn in the data center server and storage market, partially offset by increased demand for advanced computing applications by some customers.

Sales in the Telecom and Networking market decreased $1.1 million, or 2.6%, to $41.4 million for the three months ended September 30, 2023 and increased $29.3 million, or 25.3%, to $145.3 million for the nine months ended September 30, 2023 as compared to the same periods in the prior year. The decrease in sales during the three month period was due to slowing market demand. The increase in sales for the nine month period was primarily due to substantially improved material availability, allowing us to largely fulfill outstanding demand from the prior year.

GROSS PROFIT

For the three months ended September 30, 2023, gross profit decreased $43.9 million to $147.3 million, or 35.9% of revenue, as compared to $191.2 million, or 37.0% of revenue, in the same period in the prior year. For the nine months ended September 30, 2023, gross profit decreased $48.2 million to $449.5 million, or 35.9% of revenue, as compared to $497.7 million, or 36.7% of revenue, in the same period in the prior year.

The decrease in gross profit as a percentage of revenue for the three and nine months ended September 30, 2023 was largely due to the decline in sales, unfavorable product mix, and higher operating costs based on investments made in 2022, partially offset by lower premiums and related recoveries for securing critical parts.

OPERATING EXPENSES

Research and Development

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

R&D expenses increased $0.6 million to $50.4 million for the three months ended September 30, 2023 and increased $12.0 million to $153.4 million for the nine months ended September 30, 2023 as compared to the same periods in the prior year. The increase in R&D expense for the three months ended September 30, 2023 was primarily driven by increased headcount and compensation costs. The increase for the nine months ended September 30, 2023 was primarily driven by increased headcount and compensation costs of $8.3 million, which was partially due to the SL Power acquisition. In addition, during the nine months ended September 2023, we incurred $3.8 million in higher program and material costs as we invested 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, corporate development, and human resource functions.

Selling, general and administrative (“SG&A”) expenses decreased $1.6 million to $55.1 million for the three months ended September 30, 2023 and increased $5.0 million to $166.1 million for the nine months ended September 30, 2023 as compared to the same periods in the prior year. The decrease in SG&A during the three month period was primarily due to lower employee variable compensation expense, partially offset by higher stock-based compensation cost. The increase in SG&A for the nine month period was primarily related to higher stock-based compensation cost and the addition of SL Power, partially offset by lower employee variable compensation expense.

Amortization of Intangibles

Amortization expense remained the same at $7.0 million during the three months ended September 30, 2023 and increased $2.1 million to $21.2 million for the nine months ended September 30, 2023 as compared to the same periods in the prior year. The increase was primarily driven by incremental amortization of acquired intangible assets from the SL Power acquisition. For additional information, see Note 2. Acquisitions and Note 12. Intangible Assets in Part I, Item 1 “Unaudited Consolidated Financial Statements.”

Restructuring

In the fourth quarter of 2022, we approved a restructuring plan (the “2022 Plan”), which is expected to further improve our operating efficiencies and drive the realization of synergies from our business combinations by consolidating our operations, optimizing our factory footprint, including moving certain production into our higher volume factories, reducing redundancies, and lowering our cost structure. The majority of these actions impact our factory operations and should partially mitigate the impact of lower volumes on gross margins. Although we expect additional charges under this plan as we refine and execute our actions, we anticipate the 2022 Plan will be substantially completed, and associated expenses will be incurred, by the end of 2024.

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

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 decreased $4.4 million to $4.5 million for the three months ended September 30, 2023, and decreased $5.0 million to $6.3 million for the nine months ended September 30, 2023 as compared to the same periods in the prior year.

The decrease in income between periods was primarily a result of lower unrealized foreign exchange gains and a one-time gain in 2022 from the sale of intellectual property from a previous acquisition that did not recur in 2023. In addition, we experienced an increase in interest expense due to a higher interest rate on the portion of our Term Loan Facility subject to a variable interest rate and the issuance of our Convertible Notes. This was partially offset by higher interest income on our cash due to higher interest rates and additional cash on hand in the last month of the quarter as a result of the Convertible Notes issuance.

See Note 18. Long-Term Debt in Part I, Item 1 “Unaudited Consolidated Financial Statements” for information regarding our Convertible Notes.

PROVISION FOR INCOME TAX

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

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended September 30, | ​ | Nine Months Ended September 30, | ​
​ |  | 2023 |  | 2022 |  | 2023 |  | 2022 | ​
Income from continuing operations, before income tax | ​ | $ | 34,525 | ​ | $ | 86,512 | ​ | $ | 106,263 | ​ | $ | 186,341 | ​
Provision for income tax | ​ | $ | 874 | ​ | $ | 11,639 | ​ | $ | 13,405 | ​ | $ | 29,795 | ​
Effective tax rate | ​ | ​ | 2.5% | ​ | ​ | 13.5% | ​ | ​ | 12.6% | ​ | ​ | 16.0% | ​

Table of Contents

​

Our effective tax rates differ from the U.S. federal statutory rate of 21% for the three and nine months ended September 30, 2023 and 2022, 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 the three and nine months ended September 30, 2023 was lower than the same periods in 2022 primarily due to the greater impact of beneficial discrete items primarily related to tax strategies we implemented in the three months ended September 30, 2023 relative to the beneficial discrete items recorded in the three months ended September 30, 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, and make business decisions, including developing budgets and forecasting future periods. In addition, management’s incentive plans include these non-GAAP measures as criteria for achievements. These non-GAAP measures are not in accordance with U.S. GAAP and may differ from non-GAAP methods of accounting and reporting used by other companies. However, we believe these non-GAAP measures provide additional information that enables readers to evaluate our business from the perspective of management. The presentation of this additional information should not be considered a substitute for results prepared in accordance with U.S. GAAP.

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

Impact of Inflation

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

Liquidity and Capital Resources

Liquidity

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. Long-Term Debt in Part I, Item 1 “Unaudited Consolidated Financial Statements”).

​

37

Table of Contents

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

​ | ​ | ​ | ​
​ | ​ | September 30, 2023
Cash and cash equivalents | ​ | $ | 985,931
Marketable securities | ​ |  | 155
Total cash, cash equivalents, and marketable securities | ​ | $ | 986,086

​

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

Debt

On September 12, 2023, we completed a private, unregistered offering of $575.0 million Convertible Notes and received net proceeds of approximately $562.1 million after the discount for the initial purchasers’ fees. We intend to use the net proceeds to fund future growth, which may include strategic acquisitions, opportunistically repay existing outstanding indebtedness, repurchase our common stock, or general corporate purposes.

The following table summarizes our borrowings (in thousands, except for interest rates).

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | September 30, 2023
​ | ​ | Balance |  | Interest Rate |  | Unused Line Fee
Convertible Notes | ​ | $ | 575,000 | ​ | 2.50% | ​ | —
Term Loan Facility at fixed interest rate due to interest rate swap | ​ | ​ | 225,094 | ​ | 1.17% | ​ | —
Term Loan Facility at variable interest rate | ​ | ​ | 134,906 | ​ | 6.17% | ​ | —
Revolving Facility at variable interest rate | ​ | ​ | — | ​ | 6.17% | ​ | 0.10%
Total borrowings | ​ | $ | 935,000 | ​ | ​ | ​ | ​

As of September 30, 2023, 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 $115.0 million.

For more information see Note 18 Long-Term Debt 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.”

Dividends

During the three months ended September 30, 2023, we paid a quarterly cash dividend of $0.10 per share, totaling $3.8 million. We currently anticipate that a cash dividend of $0.10 per share will continue to be paid on a quarterly basis, although the declaration of any future cash dividend is at the discretion of the Board of Directors (“the Board”) and will depend on our financial condition, results of operations, capital requirements, business conditions, and other factors.

Net Cash From Operating Activities

Net cash from operating activities from continuing operations for the nine months ended September 30, 2023, was $128.2 million, as compared to $113.0 million for the same period in the prior year. The increase of $15.2 million in net cash flows from operating activities as compared to the same period in the prior year was primarily due to a favorable decrease in net operating assets driven primarily by a decrease in accounts receivable and inventories. This was partially offset by a decrease in accounts payable and accrued expenses and lower net income from continuing operations.

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. Summary of Operations and Significant Accounting Policies and Estimates to the consolidated financial statements in the 2022 Form 10-K 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 the 2022 Form 10-K, 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 exposure to interest rate risk from our investments and Credit Agreement. We also have exposure to foreign exchange rate risk related to our foreign operations and foreign currency transactions.

See “Risk Factors” set forth in Part I, Item 1A of the 2022 Form 10-K and Part II 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, 2022.

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.

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 debt. The following table summarizes our borrowings (in thousands).

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | September 30, 2023
​ | ​ | Balance |  | Interest Rate |  | Unused Line Fee
Convertible Notes | ​ | $ | 575,000 | ​ | 2.50% | ​ | —
Term Loan Facility at fixed interest rate due to interest rate swap | ​ | ​ | 225,094 | ​ | 1.17% | ​ | —
Term Loan Facility at variable interest rate | ​ | ​ | 134,906 | ​ | 6.17% | ​ | —
Revolving Facility at variable interest rate | ​ | ​ | — | ​ | 6.17% | ​ | 0.10%
Total borrowings | ​ | $ | 935,000 | ​ | ​ | ​ | ​

​

For more information see Note 18 Long-Term Debt 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 the Base Rate or SOFR, as defined in the Credit Agreement, plus an applicable margin. The interest rate swap contracts expire on September 10, 2024. After that date, this portion of our Term Loan Facility will be subject to a variable interest rate.

Our interest payments are impacted by interest rate fluctuations. With respect to the portion of our Credit Agreement that is subject to 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 Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SECs rules and forms. These disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Principal Executive Officer (Stephen D. Kelley, President and Chief Executive Officer) and Principal Financial Officer (Paul Oldham, Executive Vice President and Chief Financial Officer), as appropriate, to allow timely decisions regarding required disclosures.

As of the end of the period covered by this report, we conducted an evaluation, with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures pursuant to the Exchange Act Rule 13a-15(b). Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2023. The conclusions of the Chief Executive Officer and Chief Financial Officer from this evaluation were communicated to the Audit and Finance Committee. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. We intend to continue to review and document our disclosure controls and procedures, including our internal controls over financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

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 the 2022 Form 10-K. 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. Aside from the risk factors below, there have been no material changes to the risk factors previously disclosed in the 2022 Form 10-K.

The conditional conversion feature of the Convertible Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion feature of the Convertible Notes is triggered, holders will be entitled to convert at any time during specified periods at their option. If one or more holders elect to convert, we would be required to settle any converted principal amount of such notes through payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Convertible Notes as current rather than long-term liability, which would result in a material reduction of our net working capital.

Conversion of the Convertible Notes may dilute the ownership interest of our stockholders and the existence of the Convertible Notes may depress the price of our common stock.

The conversion of some or all of the Convertible Notes may dilute the ownership interests of our stockholders. Upon conversion, we have the option to pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock with respect to the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted. If we elect to settle the remainder, if any, of our conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted in shares of our common stock or a combination of cash and shares of our common stock, that action will dilute the ownership interest of our stockholders. Additionally, any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock.

In addition, the existence of the Convertible Notes may encourage short selling by market participants because the conversion could be used to satisfy short positions, and the anticipated conversion into shares of our common stock could depress the price of our common stock.

The hedges and warrants in our own common stock may adversely affect the common stock’s trading price.

In September 2023, we entered into hedge and warrant transactions on our own common stock. These contracts are expected to reduce the potential dilution to our common stock upon any conversion of the Convertible Notes and/or offset any cash payments we are required to make in excess of the principal amount. The warrants could separately have a dilutive effect on our common stock to the extent that the market price per share of our common stock exceeds the exercise price.

44

Table of Contents

In addition, the counterparties or their affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to our common stock and sell our common stock prior to the maturity of the Convertible Notes (and are likely to do in connection with any conversion or redemption). This activity could cause fluctuations in the market price of our common stock.

We are subject to counterparty default risk with respect to the Note Hedges.

The counterparties are financial institutions, and we will be subject to the risk that any or all of them might default. Our exposure is not secured by any collateral. If a counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor. Our exposure will depend on many factors but, generally, an increase in our exposure will correlate to an increase in the market price and in the volatility of our common stock. In addition, upon a default by a counterparty, we may suffer adverse tax consequences and more dilution than we currently anticipate with respect to our common stock. We can provide no assurances as to the financial stability or viability of the counterparties.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

​

To repurchase shares of our common stock, we periodically enter into stock repurchase agreements, open market transactions, and/or other transactions in accordance applicable federal securities laws. Before repurchasing our shares, we consider the market price of our common stock, the nature of other investment opportunities, available liquidity, cash flows from operations, general business and economic conditions, and other relevant factors.

The following table summarizes these repurchases:
