~~Company also records deferred revenue related to installation services when consideration is received before the services have~~ been performed. The standalone selling price for installation services is determined based on the estimated number of days of service technician time required for installation at standard service rates. The Company recognizes customer deposits and deferred revenue as net sales after control of the goods or services has been transferred to the customer and all revenue recognition criteria are met. The Company bills customers for extended warranties upon entering into the agreement with the customer, resulting in deferred revenue that is recognized over the period of the extended warranty contract. The Company recognizes revenue over time on contracts for the sale of large scale materials processing systems. The timing of customer payments on these contracts generally differs from the timing of revenue recognized. If revenue recognized exceeds customer payments, a contract asset is recorded and if customer payments exceed revenue recognized, a contract liability is recorded. Contract assets are included within prepaid expense and other current assets on the condensed consolidated balance sheets. Contract liabilities are included within accrued expenses and other current liabilities on the condensed consolidated balance sheets. Certain deferred revenues related to extended warranties in excess of one year from the balance sheet date are included within other long-term liabilities and deferred income taxes on the condensed consolidated balance sheets.

The following table reflects the changes in the Company's contract assets and liabilities for the nine months ended September 30, ~~2022~~2023 and ~~2021:~~2022:

5. FAIR VALUE MEASUREMENTS

The Company's financial instruments consist of cash equivalents, short-term investments, accounts receivable, accounts payable, drawings on revolving lines of credit, long-term debt and interest rate ~~swaps and contingent purchase consideration.~~swaps.

The valuation techniques used to measure fair value are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy: Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company classifies its financial instruments according to the prescribed criteria.

The ~~carrying amounts~~fair value of money market fund deposits, term deposits, accounts receivable, accounts payable and drawings on revolving lines of credit ~~are considered reasonable estimates of~~is reasonably close to their ~~fair market value~~carrying amounts due to the short maturity of most of these instruments or as a result of the competitive market interest rates, which have been negotiated.

The Company entered into an interest rate swap that is designated as a cash flow hedge associated with a long-term note issued during the second quarter of 2016 that will terminate with the long-term note in May 2023. The fair value at September 30, 2022 for the interest rate swap considered pricing models whose inputs are observable for the securities held by the Company.

At September 30, 2022, the Company's long-term note consisted of a variable rate note. The carrying value of the note approximates the estimated fair value of $16,328. At December 31, 2021, the Company's long-term notes consisted of a variable rate note and a fixed rate note. The fair value of the notes were estimated using a discounted cash flow model using observable market interest rates. The fair value of the long-term notes, including the current portion, at December 31, 2021, was $34,226 as compared to the carrying value of $34,157. The long-term notes were reported at amortized cost on the condensed consolidated balance sheets and were classified within Level 2 of the fair value hierarchy.

The fair values of contingent purchase consideration at December 31, 2021 were determined using an income approach at the respective business combination date and at the reporting date. The approach is based on significant inputs that are not observable in the market and include key assumptions such as assessing the probability of meeting certain milestones required to earn the contingent purchase consideration. The contingency period ended during the nine months ended September 30, 2022.

5. RESTRUCTURING AND IMPAIRMENT OF LONG-LIVED ASSETS

In the fourth quarter of 2022, the Company implemented a restructuring program at its Russian subsidiary. In the third quarter of 2023, the Company substantially completed the restructuring program. As a result, the remaining restructuring accrual was substantially recovered. This resulted in net restructuring recoveries of $1,501 and $357 for the three and nine months ended September 30, 2023, respectively. There was no restructuring related activity for the three or nine months ended September 30, 2022.

The remaining restructuring accrual was included in accrued expenses and other current liabilities in the Company's condensed consolidated balance sheets. Activity related to the restructuring accrual was as follows:


	Nine Months Ended September 30,

Balance, beginning of period	$	4,869
Charges	1,367
Cash payments	(3,630)
Recoveries	(1,724)

~~12.~~11. COMMITMENTS AND CONTINGENCIES

From time to time, the Company may be involved in legal disputes and other proceedings in the ordinary course of its business. These matters may include allegations of infringement of intellectual property, commercial disputes and employment matters. As of September 30, ~~2022~~2023 and through the filing date of these condensed consolidated financial statements, the Company is aware of no ongoing legal proceedings that management estimates could have a material effect on the Company's Consolidated Financial Statements.

The Company has submitted a number of voluntary self-disclosures regarding compliance with export control laws and regulations and the U.S. Department of Justice is conducting an investigation into certain shipments of equipment. At this time, the Company is not able to estimate the amount or probability of any monetary penalties or other expenses that the Company may incur as a result of this investigation.

~~13.~~12. INCOME TAXES

The effective tax rates were ~~21.0%~~18.9% and ~~26.4%~~21.0% for the three months ended September 30, ~~2022~~2023 and ~~2021,~~2022, respectively, and ~~22.7%~~23.8% and ~~24.6%~~22.7% for the nine months ended September 30, ~~2022~~2023 and ~~2021,~~2022 respectively. There ~~were~~was a net discrete tax ~~benefits~~detriment of ~~$3,644 and $1,424~~$169 for the three months ended September 30, ~~2022~~2023 and ~~2021, respectively,~~a net discrete tax benefit of $3,644 for the three months ended September 30, 2022. In the third quarter of 2023, the impact of relatively lower profits in high tax jurisdictions helped to reduce the third quarter tax rate by more than the impact of the reduced discrete benefits. There was a net discrete tax detriment of $390 and a net discrete tax benefit of $6,806 ~~and $5,849~~ for the nine months ended September 30, 2023 and 2022, respectively. The discrete detriment for the three and ~~2021, respectively.~~nine months ended September 2023 did not have a significant effect on the Company's tax rate. The 2022 discrete items include a reduction in taxes as a result of filing amended returns to obtain foreign tax incentives for capital investments in prior years and to changes in tax position agreed to with tax authorities for prior year ~~audits. The 2022 benefit is~~audits which were partly offset by the impact from tax deductions for equity-based compensation that were less than the compensation expense recognized for books. ~~The 2021 discrete items relate primarily to tax deductions for equity based compensation that exceeded book deductions and to provision to return adjustments.~~

The Company accounts for its uncertain tax positions in accordance with the accounting standards for income taxes. The Company classifies interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes. The following is a summary of the activity of the Company’s unrecognized tax benefits for the nine months ended September 30, 2023 and 2022:


	Nine Months Ended September 30,
	2023		2022
Balance, beginning of period	$	15,841	$	19,209
Change in prior period positions	(1,274)		(603)
Additions for tax positions in current period	3,738		—
Foreign currency translation	(527)		865
Balance, end of period	$	17,778	$	19,471

The liability for uncertain tax benefits is included in other long-term liabilities and deferred income taxes at September 30, 2023 and December 31, 2022. Substantially all of the liability for uncertain tax benefits related to various federal, state and foreign income tax matters would benefit the Company's effective tax rate, if recognized.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward looking statements that are based on management's current expectations, estimates and projections about our business and operations. Our actual results may differ materially from those currently anticipated and expressed in such forward-looking statements. See "Cautionary Statement Regarding Forward-Looking Statements."

Overview

We develop, manufacture and sell high-performance fiber lasers and diode lasers that are used for diverse applications, primarily in materials processing. We also manufacture and sell complementary products used with our lasers including optical delivery cables, fiber couplers, beam switches, optical processing heads, in-line sensors and chillers. In addition, we offer laser-based and non-laser based systems for certain markets and applications. Our portfolio of laser solutions is used in materials processing, medical and advanced applications. We sell our products globally to original equipment manufacturers ("OEMs"), system integrators and end users. We market our products internationally, primarily through our direct sales force. Our major manufacturing facilities are located in the United States ~~Germany, Russia~~ and ~~Belarus.~~Germany. In response to the risks from the Russia-Ukraine conflict, we have substantially reduced our reliance on our Russian operations, and have ceased new investments in our Russian and Belarus operations. We have and will continue to expand our manufacturing operations in Germany and the United States, and have added manufacturing capacity in Italy and Poland to meet the demand for our products and our sales and support needs. We have sales and service offices and applications laboratories worldwide.

We are vertically integrated such that we design and manufacture most of the key components used in our finished products, from semiconductor diodes to optical fiber preforms, finished fiber lasers and complementary products. Our vertically integrated operations allow us to reduce manufacturing costs, control quality, rapidly develop and integrate advanced products and protect our proprietary technology.

Factors and Trends That Affect Our Operations and Financial Results

In reading our financial statements, you should be aware of the following factors and trends that our management believes are important in understanding our financial performance.

~~Recent Events.~~Russia-Ukraine Conflict. The Russia-Ukraine conflict and the sanctions imposed in response to this crisis have significantly curtailed our ability to use our manufacturing operations in Russia to supply other IPG operations outside of Russia. The conflict and the risk of additional sanctions has also increased the levels of uncertainty and risks facing the Company. While sales to third-parties in Russia were approximately 2% of our revenue in the first three quarters of 2022, we rely on our facility in Russia to manufacture certain components that are used in our other manufacturing facilities. In addition, we supply finished products to China from Russia. The total value of product shipped to the Chinese market from Russia was approximately $50 million for the nine months ended September 30, 2022 of which $8 million was shipped in the third quarter. At September 30, 2022, we had working capital excluding cash and short-term investments of $150.5 million in Russia of which $116.4 million is inventory. In addition, we had $44.0 million cash and short term investments in Russia. The net asset value of our long lived assets was $94.7 million. We also have a factory in Belarus that supplies certain componentsCompany due to our ~~other~~ manufacturing facilities. The value of the long lived assets in Belarus was $44.0 million at September 30, 2022, and we had working capital excluding cash and short-term investments of $6.5 million in Belarus of which $5.5 million is inventory. In addition, we had $4.0 million cash and short term investmentsoperations in Belarus.

Since the start of the conflict, we have been navigating complex and evolving regulations, including sanctions, without material disruption to our ability to meet customer demand. Certain sanctions increase the cost of operating in Russia and Belarus as a result of shipping limitations, logistics challenges and changes in tariffs. Trade restrictions further limited our ability to ship components to Russia from Germany during the third quarter. The U.S. increased tariffs on Russian and Belarus goods late in the first quarter of 2022, impacting the results of operations for the remainder of the 2022.

~~In response to the risks from the Russia-Ukraine conflict, we are~~ executing on plans to reduce our reliance on our Russia and Belarus operations by adding capacity in other countries, increasing inventories worldwide and qualifying third-party suppliers. In ~~the first three quarters of~~ 2022, we began hiring and training additional employees, expanding capacity for increased production, and running additional shifts in the U.S. and ~~Europe. These~~Germany and adding additional manufacturing capacity in Italy and Poland.

We believe the contingency measures outlined above that we have already put in place mitigate substantially all the effects of the recent sanctions on our ability to supply finished products to customers. If we have not fully mitigated the effect of these and other trade restrictions, or if new sanctions are adopted, our ability to supply finished products to customers could be impacted. Although we believe our contingency plans ~~also include~~mitigate the risk of our ability to supply customers with finished product, these plans require additional investments in facilities outside of Russia and Belarus in the near term as well as additional ongoing operating costs, primarily associated with the higher cost of labor outside of Russia and Belarus. While we have sufficient financial resources to make these investments and expenditures, our gross margins and ~~other~~ financial results have been and will be adversely impacted by increased operating costs associated with these transitions. Over time, we intend to mitigate some of these increases by producing components in countries with ~~cost reductions,~~lower labor costs than the United States and Germany, with ongoing product expense reduction initiatives, higher productivity from automation, improved yields and product specifications.

~~In October 2022, the European Union introduced new sanctions that will restrict our ability~~ We are also continuing to ship and receive components from our factory in Russia to the E.U. beginning in January 2023. We believe the contingency measures outlined above that we have already put in place will mitigate the effect of the new sanctions. If we have not fully mitigated the effect of

these and other trade restrictions, our ability to supply finished products to customers could be impacted after they take effect. Our Board of Directors has been monitoring and continues to assess and monitor risks to our business associated with the Russia-Ukraine conflict.

We evaluated the recoverability of certain assets located in Russia during the fourth quarter of 2022 and incurred impairment charges that reduced the value of fixed assets, inventory and other current assets. We also incurred restructuring charges in 2022 and 2023. As of September 30, 2023, we have substantially completed the restructuring program in Russia and

recovered the majority of the remaining restructuring charges accrual. Refer to Note 5 "Restructuring and Impairment of Long-lived Assets" in the notes to the condensed consolidated financial statements for further information.

Sales to third-parties in Russia were approximately 3% of our revenue for both the first three quarters of 2023 and the full year ended December 31, 2022. Our Russian subsidiary has historically supplied finished goods for our China market. Sanctions have limited our ability to provide components to Russia for the completion of finished lasers. Although our Russian operation has built safety stock in anticipation of this situation, we are also producing more finished lasers for China at other IPG locations. The total value of product shipped to the Chinese market from Russia was approximately $13.3 million for the nine months ended September 30, 2023 and $61.5 million for the full year ended December 31, 2022.

At September 30, 2023, we had working capital excluding cash and cash equivalents of $21.2 million in Russia of which $18.1 million is inventory. We had $63.7 million of cash and cash equivalents in Russia. The net asset value of our Russian subsidiary was $87.9 million. In addition to the impairment charges referenced above, the net value of assets in Russia has been reduced by $146.2 million due to the cumulative translation effect of the Russian ruble compared to the U.S. dollar, which is included in the accumulated other comprehensive loss component of stockholders' equity. Depending upon the outcome of our review of our Russian operations, we may incur additional asset impairment charges and the cumulative translation effect of foreign exchange fluctuations that is currently included in accumulated other comprehensive loss on our condensed consolidated balance sheets may be charged to our condensed consolidated statements of income.

We continue to manufacture laser cabinets and other mechanical components in Belarus. Trade sanctions to date have not significantly affected our ability to supply these items from Belarus to other manufacturing locations. The value of the long lived assets in Belarus was $31.3 million at September 30, 2023, and we had working capital excluding cash of $4.9 million in Belarus of which $4.5 million is inventory. In addition, we had $5.1 million of cash in Belarus.

COVID-19. Global demand trends have been impacted by the ongoing COVID-19 ~~pandemic and therefore remain uncertain at this time~~.pandemic. While business conditions generally improved from the severe contraction experienced in 2020, it is difficult to predict whether conditions could change if there are additional restrictions imposed as a result of a resurgence in COVID-19 infections. To date, we have been able to accommodate these changes to our business operations and continue to meet customer demand. If guidelines or mandates from relevant authorities becomes more restrictive due to a resurgence of COVID-19 in a particular region, the effect on our operations could be more significant. ~~This uncertainty continues to make forecasting our business challenging in the near to medium-term.~~

Supply Chain. We and our customers are experiencing increased lead times and costs for certain components purchased from third party suppliers; particularly electronic components. We, our customers and our suppliers continue to face constraints related to supply chain and logistics, including availability of capacity, materials, air cargo space, sea containers and higher freight rates. ~~Supply~~While supply chain and logistics constraints ~~are expected~~have moderated, they have not yet fully returned to ~~continue for the foreseeable future and could impact our ability to supply products and our customers' demand for our product or readiness to accept deliveries.~~pre-pandemic conditions. Supply chain constraints have not significantly affected our business but they have moderately increased our freight costs, caused us to carry higher levels of safety stock for certain inventory items, and increased the cost of certain electronic components, pushed out customer deliveries and caused delays in recognizing revenue for certain custom processing systems in our Genesis business due to delays in receiving robots. Notwithstanding these effects, we believe we have the ability to meet the near-term demand for our products, but the situation is fluid and subject to change.components.

Net sales. Our net sales have historically fluctuated from quarter to quarter. The increase or decrease in sales from a prior quarter can be affected by the timing of orders received from customers, the timing of shipments, the mix of OEM orders and one-time orders for products with large purchase prices, competitive pressures, acquisitions, economic and political conditions in a certain country or region and seasonal factors such as the purchasing patterns and levels of activity throughout the year in the regions where we operate. Net sales can be affected by the time taken to qualify our products for use in new applications in the end markets that we serve. Our sales cycle varies substantially, ranging from a period of a few weeks to as long as one year or more, but is typically several months. The adoption of our products by a new customer or qualification in a new application can lead to an increase in net sales for a period, which may then slow until we penetrate new markets or obtain new customers. Foreign exchange rates also affect our net sales, due to changes in the U.S. dollar value of sales made in foreign currencies.

Our business depends substantially upon capital expenditures by end users, particularly by manufacturers using our products for materials processing, which includes general manufacturing, automotive including electric vehicles ("EV"), other transportation, aerospace, heavy industry, consumer, semiconductor and electronics. Approximately ~~91%~~90% of our revenues for both the first three quarters of ~~2022~~2023 and the full ~~2021~~2022 fiscal year, were from customers using our products for materials processing. Although applications within materials processing are broad, the capital equipment market in general is cyclical and historically has experienced sudden and severe downturns. For the foreseeable future, our operations will continue to depend upon capital expenditures by end users of materials processing equipment and will be subject to the broader fluctuations of capital equipment spending.

In response to inflation, some global central banks are adopting less accommodative monetary policy and have or expect to increase benchmark interest rates. An increase in interest rates could impact global demand and/or could lead to a recession

Table of Contents

that may reduce the demand for our products. In addition, an increase in interest rates would increase the cost of equipment financed with leases or debt.

In recent years, our net sales and margins have been negatively impacted by tariffs and trade policy. New tariffs and other changes in U.S. trade policy could trigger retaliatory actions by affected countries, and certain foreign governments.

We are also susceptible to global or regional disruptions such as political instability, geopolitical conflicts, acts of terrorism, significant fluctuations in currency values, natural disasters, macroeconomic concerns and the impact of the COVID-19 outbreak that affect the level of capital expenditures or global commerce. With respect to the COVID-19 outbreak specifically, the possible ~~affect~~effect over the longer term remains uncertain and dependent on future developments that cannot be

accurately predicted at this time, such as the severity and transmission rate of COVID-19 or new variants, the extent and effectiveness of containment actions taken, the approval, effectiveness, timing and widespread vaccination of the global population, and the impact of these and other factors on our customer base and general commercial activity.

The average selling prices of our products generally decrease as the products mature. These decreases result from factors such as increased competition, decreased manufacturing costs and increased unit volumes. We may also reduce selling prices in order to penetrate new markets and applications. Furthermore, we may negotiate discounted selling prices from time to time with certain customers that place high unit-volume orders.

The secular shift to fiber laser technology in large materials processing applications, such as cutting applications, had a positive effect on our sales trends in the past such that our sales trends were often better than other capital equipment manufacturers in both positive and negative economic cycles. As the secular shift to fiber laser technology matures in such applications, our sales trends are more susceptible to economic cycles which affect other capital equipment manufacturers broadly and the machine tool and industrial laser industries more specifically.

Gross margin. Our total gross margin in any period can be significantly affected by a number of factors, including net sales, production volumes, competitive factors, product mix, and by other factors such as changes in foreign exchange rates relative to the U.S. dollar, tariffs and shipping costs. Many of these factors are not under our control. The following are examples of factors affecting gross margin:

•As our products mature, we can experience additional competition which tends to decrease average selling prices and affects gross margin;

•Our gross margin can be significantly affected by product mix. Within each of our product categories, the gross margin is generally higher for devices with greater average power. These higher power products often have better performance, more difficult specifications to attain and fewer competing products in the marketplace;

•Higher power lasers also use a greater number of optical components, improving absorption of fixed overhead costs and enabling economies of scale in manufacturing;

•The gross margin for certain specialty products may be higher because there are fewer or sometimes no equivalent competing products;

•Customers that purchase devices in greater unit volumes generally are provided lower prices per device than customers that purchase fewer units. In general, lower selling prices to high unit volume customers reduce gross margin although this may be partially offset by improved absorption of fixed overhead costs associated with larger product volumes, which drive economies of scale;

•Gross margin on systems can be lower than gross margin for our laser, depending on the configuration, volume and competitive forces, among other factors; ~~and finally,~~

•Persistent inflation leading to increases in average manufacturing salaries as well as an increase in the purchase price of components including, but not limited to, electronic components and metal parts could negatively impact gross margin if we are not able to pass those increases on to customers by increasing the selling price of our ~~products.~~products; and finally,

•Changes in relative exchange rates between currencies we receive when selling our products and currencies we use to pay our manufacturing expenses.

We expect that some new technologies, products and systems will have returns above our cost of capital but may have gross margins below our corporate average. If we are able to develop opportunities that are significant in size, competitively advantageous or leverage our existing technology base and leadership, our current gross margin levels may not be maintained.

Table of Contents

Instead, we aim to deliver industry-leading levels of gross margins by growing sales, by taking market share in existing markets, or by developing new applications and markets we address, by reducing the cost of our products and by optimizing the efficiency of our manufacturing operations.

A high proportion of our costs is fixed so costs are generally difficult to adjust or may take time to adjust in response to changes in demand. In addition, our fixed costs increase as we expand our capacity. If we expand capacity faster than is required by sales growth, gross margins could be negatively affected. Gross margins generally decline if production volumes are lower as a result of a decrease in sales or a reduction in inventory because the absorption of fixed manufacturing costs will be reduced. Gross margins generally improve when the opposite occurs. If both sales and inventory decrease in the same period, the decline in gross margin may be greater if we cannot reduce fixed costs or choose not to reduce fixed costs to match the decrease in the level of production. If we experience a decline in sales that reduces absorption of our fixed costs, or if we have production issues, our gross margins will be negatively affected.

~~Table of Contents~~

We also regularly review our inventory for items that are slow-moving, have been rendered obsolete or are determined to be excess. Any provision for such slow-moving, obsolete or excess inventory affects our gross margins. For example, we recorded provisions for slow-moving, obsolete or excess inventory totaling ~~$12.9~~$9.1 million and ~~$7.9~~$12.9 million for the three months ended September 30, ~~2022~~2023 and ~~2021,~~2022, respectively, and ~~$38.4~~$32.4 million and ~~$23.5~~$38.4 million for the nine months ended September 30, ~~2022~~2023 and ~~2021,~~2022, respectively.

Selling and general and administrative expenses. In the past, we invested in selling and general and administrative costs in order to support continued growth in the Company. As the secular shift to fiber laser technology matures, our sales growth becomes more susceptible to the cyclical trends typical of capital equipment manufacturers. Accordingly, our future management of and investments in selling and general and administrative expenses will also be influenced by these trends, although we may still invest in selling or general and administrative functions to support certain initiatives even in economic down cycles. Certain general and administrative expenses are not related to the level of sales and may vary quarter to quarter based primarily upon the level of acquisitions, divestitures and litigation.

Research and development expenses. We plan to continue to invest in research and development to improve our existing components and products and develop new components, products, systems and applications technology. We believe that these investments will sustain our position as a leader in the fiber laser industry and will support development of new products that can address new markets and growth opportunities. The amount of research and development expense we incur may vary from period to period. As part of the telecommunications transmission product line divestiture mentioned below, we will no longer be incurring research and development expenses attributed to the development of telecommunications transmission products.

Goodwill and long-lived assets impairments. We review our intangible assets and property, plant and equipment for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill is required to be tested for impairment at least annually. Negative industry or economic trends, including reduced estimates of future cash flows, disruptions to our business, slower growth rates, lack of growth in our relevant business units, differences in the estimated product acceptance rates, or market prices below the carrying value of long-lived assets evaluated for sale could lead to impairment charges against our long-lived assets, including goodwill and other intangible assets. We ~~are evaluating certain U.S.-based~~have long-lived assets ~~for sale, including land, buildings and the corporate aircraft. If the estimated sales~~in Belarus with a carrying value of ~~any~~$31.3 million. If sanctions increase or if the geopolitical situation changes such that we can no longer use Belarus as a source of ~~these assets is below carrying value, then~~supply for our laser cabinets and other mechanical components, we may need to ~~record an asset~~evaluate those assets for impairment, ~~charge.~~which may result in impairment charges.

Our valuation methodology for assessing impairment requires management to make significant judgments and assumptions based on historical experience and to rely heavily on projections of future operating performance at many points during the analysis. Also, the process of evaluating the potential impairment of goodwill is subjective. We operate in a highly competitive environment and projections of future operating results and cash flows may vary significantly from actual results. If our analysis indicates potential impairment to goodwill in one or more of our reporting units, we may be required to record charges to earnings in our financial statements, which could negatively affect our results of operations.

Foreign exchange. Because we are a U.S.-based company doing business globally, we have both translational and transactional exposure to fluctuations in foreign currency exchange rates. Changes in the relative exchange rate between the U.S. dollar and the foreign currencies in which our subsidiaries operate directly affects our sales, costs and earnings. Differences in the relative exchange rates between where we sell our products and where we incur manufacturing and other operating costs (primarily in the U.S.~~, Germany, Russia~~ and ~~Belarus)~~Germany) also affects our costs and earnings. Certain currencies experiencing significant exchange rate fluctuations like the euro, the Russian ruble, and the Chinese yuan ~~and the Japanese yen~~ have had and could have an additional significant impact on our sales, costs and earnings. For the quarter ended September 30, ~~2022,~~2023, the foreign exchange gain was primarily created by the depreciation of the euro and ~~depreciation of~~ the Russian ruble ~~were~~ partially offset by a foreign exchange loss created by the depreciation of the Chinese yuan as compared to the U.S. dollar. ~~This is because our~~Our European and Russian subsidiaries have certain net assets denominated in U.S. dollars, and our Chinese subsidiary has certain net liabilities denominated in U.S. dollars.

Table of Contents

Our ability to adjust the foreign currency selling prices of products in response to changes in exchange rates is limited and may not offset the impact of the changes in exchange rates on the translated value of sales or costs. In addition, if we increase the selling price of our products in local currencies, this could have a negative impact on the demand for our products.

Income taxes. We are evaluating the impact of countries adopting tax legislation in accordance with the proposals presented by the OECD (Pillars 1 and 2). Based on the current drafts of the proposals, the tax impact in most countries will not be significant in 2024 due to an effective tax rate in those countries in excess of 15% or as a result of the transition rules that are proposed.

Major customers. While we have historically depended on a few customers for a large percentage of our annual net sales, the composition of this group can change from period to period. Net sales derived from our five largest customers as a percentage of our net sales was ~~16%~~14% for the nine months ended September 30, ~~2022~~2023 and ~~19%~~15%, and ~~24%~~19% for the full years ~~2021~~2022 and ~~2020,~~2021, respectively. One of our customers accounted for ~~13%~~16% and ~~22%~~14% of our net accounts receivable at September 30, ~~2022~~2023 and December 31, ~~2021,~~2022, respectively. We seek to add new customers and to expand our relationships with existing customers. We anticipate that the composition of our significant customers will continue to change. We generally do not enter into agreements with our customers obligating them to purchase a fixed number or large volume of our products. If any of our significant customers substantially reduced their purchases from us, our results would be adversely affected.

Effect of exchange rates on net sales, gross profit and operating expenses. We estimate that, if exchange rates relative to the U.S. dollar had been the same as one year ago, which were on average euro ~~0.85,~~0.99, Russian ruble ~~73,~~59, Japanese yen ~~110~~138 and Chinese yuan ~~6.47,~~6.85, respectively, we ~~would have expected~~estimate that net sales for the three months ended September 30, ~~2022 to be $26.0~~2023 would have been $5.7 million higher, gross profit ~~to be $13.7~~would have been $4.4 million higher and total operating expenses would have been ~~$0.5~~$1.2 million higher.

~~Gain on divestiture.~~Impairment of long-lived assets. ~~During~~We recorded a non-cash long-lived asset impairment charge of $1.2 million for the ~~quarter~~three months ended September 30, ~~2022, we divested our telecommunications transmission product lines for $56.2 million. The divestiture resulted in a gain of $21.7~~2023 as compared to $0.9 million for the ~~quarter-ended~~three months ended September 30, ~~2022.~~2023, related to the right-of-use ("ROU") asset for a leased building associated with our Submarine Network Division business that was previously divested. Attempts to sublease the space have been unsuccessful. As of September 30, 2023, the ROU asset related to this lease has been reduced to zero.

Restructuring charges (recoveries), net. In the third quarter of 2023, we substantially completed the restructuring program at our Russian subsidiary. As a result, we released $1.5 million that had been accrued in relation to restructuring expenses.

Gain on foreign exchange. We incurred a foreign exchange transaction gain of ~~$0.5~~$0.4 million for the three months ended September 30, ~~2022~~2023 as compared to a ~~$3.6~~$0.5 million gain for the three months ended September 30, ~~2021.~~2022.

Materials processing

Sales for materials processing applications decreased due to decreases in sales of high power CW lasers, pulsed lasers, medium power CW lasers and QCW lasers, partially offset by higher sales of laser and non-laser systems ~~pulsed lasers,~~and other laser products and ~~service and medium power CW lasers.~~service.

•High power CW laser sales decreased due to lower sales for cutting applications ~~partially offset by an increase in sales for welding applications. Within cutting applications, the decrease in sales was attributable~~due to softer demand in China and Europe and increased competition in China. ~~The increase in sales of high power CW lasers used in welding applications was driven by higher sales supporting E-mobility including electric vehicles, battery manufacturing and electric motors.~~

•The ~~increase~~decrease in medium power CW sales related to ~~an increase~~a decrease in demand for ~~welding~~micromaterial processing and ~~additive manufacturing applications,~~cutting, partially offset by ~~a decrease in cutting applications.~~additive manufacturing.

Other Applications

Sales from other applications ~~increased~~decreased due to ~~increased~~decreased sales in telecommunications products, as a result of the business divestiture during the third quarter of 2022, and decreased demand for lasers used in medical procedures, partially offset by ~~decreased~~increased demand for lasers used in advanced ~~applications and decreased demand for telecommunications products as well as the business divestiture during the third quarter.~~applications.

Cost of sales and gross margin. Cost of sales ~~increased~~decreased by ~~$35.4~~$40.4 million, or ~~6.3%~~6.7%, to $561.0 million for the nine months ended September 30, 2023 from $601.4 million for the nine months ended September 30, ~~2022 from $566.0 million~~2022. Our gross margin decreased to 43.2% for the nine months ended September 30, ~~2021. Our gross margin decreased to~~2023 from 45.1% for the nine months ended September 30, ~~2022 from 48.4% for the nine months ended September 30, 2021.~~2022. Gross margin decreased mainly due to an increase in cost of product sold from inventory, ~~provisions,~~partially offset by decreases in shipping costs and tariffs and ~~cost of products sold from~~inventory provisions for excess and obsolete inventory as a percentage of sales. The strong U.S. dollar has negatively affected gross margin because a disproportionate amount of our manufacturing costs are denominated in U.S. ~~dollars~~dollar as compared to our sales which are predominantly denominated in foreign ~~currency.~~currencies.

Sales and marketing expense. Sales and marketing expense increased by $4.7 million, or 8.0%, to $63.5 million for the nine months ended September 30, 2023 compared with $58.8 million for the nine months ended September 30, 2022. The increase is due to higher personnel and related costs and travel and entertainment costs, offset by lower depreciation and amortization expenses. As a percentage of sales, sales and marketing expense increased to 6.4% from 5.4% for the nine months ended September 30, 2023 and 2022, respectively.

Research and development expense. Research and development expense decreased by ~~$13.3~~$18.5 million, or ~~12.9%~~20.7%, to $71.0 million for the nine months ended September 30, 2023, compared to $89.5 million for the nine months ended September 30, ~~2022,~~2022. Decreases in personnel and related costs, amortization of production licenses, and other R&D expense are primarily the result of the divestiture of our telecommunications transmission product line in the third quarter of 2022. Further, depreciation expenses decreased primarily as a result of the impairment of Russian long-lived assets in 2022. Lastly, we incurred lower information systems and contractor expenses compared to ~~$102.8 million for~~ the nine months ended September 30, 2021, primarily as a result of a decrease in personnel and related costs, expenses related to materials used for research and development projects, and consultants costs. The decrease in personnel and related costs and expenses related to materials used for research and development was partially driven by the telecommunications transmission product line divestiture in the third quarter.2022. As a percentage of sales, research and development expense decreased to 7.2% for the nine months ended September 30, 2023 from 8.2% for the nine months ended September 30, ~~2022 from 9.4% for the nine months ended September 30, 2021.~~2022.

General and administrative expense. General and administrative expense ~~increased~~decreased by ~~$4.2~~$7.2 million, or ~~4.5%~~7.4%, to $90.7 million for the nine months ended September 30, 2023 from $97.9 million for the nine months ended September 30, 2022, ~~from $93.7 million for the nine months ended September 30, 2021,~~ primarily as a result of ~~increases~~decreases in consultant costs, ~~bad debt provisions~~repairs and ~~information systems~~maintenance costs, and depreciation expenses. The expense reductions were partially offset by ~~an increase~~a net loss of $1.3 million related to the sales of our buildings in ~~bad debt recoveries.~~Alabama and California in the third quarter of 2023. As a percentage of sales, general and administrative expense increased to 9.2% for the nine months ended September 30, 2023 from 8.9% for the nine months ended September 30, ~~2022 from 8.5% for the nine months ended September 30, 2021.~~2022.

Effect of exchange rates on net sales, gross profit and operating expenses. We estimate that, if exchange rates relative to the U.S. dollar had been the same as one year ago, which were on average euro ~~0.84,~~0.94, Russian ruble ~~74,~~70, Japanese yen ~~109~~128 and Chinese yuan ~~6.47,~~6.60, respectively, we would have expected net sales for the nine months ended September 30, ~~2022~~2023 to be ~~$54.0~~$29.8 million higher, gross profit to be ~~$28.2~~$17.6 million higher and total operating expenses would have been $3.3 million higher.

~~Gain on divestiture.~~Table of Contents

Impairment of long-lived assets. ~~During the quarter ended September 30, 2022, we divested our telecommunications transmission product lines for $56.2 million. The divestiture resulted in~~We recorded a ~~gain~~non-cash long-lived asset impairment charge of ~~$21.7~~$1.2 million for the nine months ended September 30, ~~2022.~~2023 as compared to $0.9 million for the nine months ended September 30, 2022, related to the ROU asset for a leased building associated with our Submarine Network Division business that was previously divested. Attempts to sublease the space have been unsuccessful. As of September 30, 2023, the ROU asset related to this lease has been reduced to zero.

~~Loss~~Restructuring charges (recoveries), net. In the third quarter of 2023, we substantially completed the restructuring program at our Russian subsidiary. As a result, we released $1.5 million that had been accrued in relation to restructuring expenses.

Gain on foreign exchange. We ~~incurred~~benefited from a foreign exchange transaction gain of $1.8 million for the nine months ended September 30, 2023 as compared to a loss of $11.3 million for the nine months ended September 30, ~~2022 as compared to a gain of $8.0 million for the nine months ended September 30, 2021.~~2022. Our European and Russian subsidiaries have certain net assets denominated in U.S. dollars, and our Chinese subsidiary has certain net liabilities denominated in U.S. dollars. The ~~loss~~gain for the nine months ended September 30, ~~2022~~2023 was primarily attributable to ~~loss resulted~~gain from the ~~appreciation~~depreciation of the Russian ruble, ~~and depreciation of the Chinese yuan,~~ partially offset by loss from the ~~gain from~~ depreciation of ~~the~~Chinese yuan and euro as compared to the U.S. dollar.

Interest income, ~~(expense),~~ net. Interest income, net, was ~~$4.7~~$28.4 million for the nine months ended September 30, ~~2022~~2023 as compared to ~~$1.2~~$4.7 million of ~~expense~~income for the nine months ended September 30, ~~2021.~~2022. The ~~change~~increase in interest income, ~~(expense),~~ net, iswas due to an increase in yields on cash equivalents and short-term investments that resulted infrom higher market interest rates as compared to prior year rates.

Provision for income taxes. Provision for income taxes was $55.3 million for the nine months ended September 30, 2023 compared to $59.7 million for the nine months ended September 30, 2022, ~~compared to $69.4~~representing an effective tax rate of 23.8% and 22.7% for the nine months ended September 30, 2023 and 2022, respectively. There was a net discrete tax detriment of $0.4 million and a net discrete tax benefit of $6.8 million for the nine months ended September 30, ~~2021, representing an effective tax rate of 22.7%~~2023 and ~~24.6%~~2022, respectively.

Net income attributable to IPG Photonics Corporation as a percentage of our net sales decreased by ~~1.0~~0.5 percentage point to 18.0% for the nine months ended September 30, 2023 from 18.5% for the nine months ended September 30, 2022 ~~from 19.5% for the nine months ended September 30, 2021~~ due to the factors described above.

Liquidity and Capital Resources

We believe that our existing cash and cash equivalents, short-term investments, our cash flows from operations and our existing ~~lines~~line of credit provide us with the financial flexibility to meet our liquidity and capital needs. We expect to continue making investments in capital expenditures, to assess acquisition opportunities and to repurchase shares of our stock in accordance with our repurchase program. The extent and timing of such expenditures may vary from period to period. Our future long-term capital requirements will depend on many factors including ~~investments in European and North American manufacturing capacity in order to execute plans to reduce reliance on Russia for manufacturing capacity,~~ our level of sales, the impact of the economic environment on our growth, ~~including any ongoing impact of the COVID-19 pandemic on certain global or regional economies, global or regional recessions,~~ the timing and extent of spending to support development efforts, expansion of global sales and marketing activities, government regulation including trade sanctions, the timing and introductions of new products, the need to ensure access to adequate manufacturing capacity and the continuing market acceptance of our products.

~~With respect~~ In the near term, we will incur capital expenditures related to the expansion of capacity outside of Russia because of the reduction in manufacturing activity and capacity at our Russian factory that we can access due to sanctions. As of September 30, 2023, we had no off-balance sheet arrangements that have, or are reasonably likely to have, a current ~~geopolitical situation involving Ukraine~~or future material effect on our consolidated financial condition, results of operations, liquidity, capital expenditures or capital resources.

Included in cash and ~~Russia, the imposition of capital controls by the Russian government restricts our ability to access company~~ cash ~~in Russia, but would not materially disrupt our liquidity as a whole. The current balance~~equivalents are $63.7 million of cash and cash equivalents ~~and short term investments~~located in Russia, ~~is approximately 3%~~and $5.1 million of ~~total current~~ cash and cash equivalents located in Belarus, as of September 30, 2023. Cash and ~~short term investments.~~cash equivalents in Russia are subject to capital controls that prevent repatriation by dividend or distribution of capital. There are currently no restrictions on our ability to use cash and cash equivalents in Russia for operating purposes including converting cash to foreign currency for the payment of goods received from vendors outside of Russia. The Russian operations are self-funding. ~~We attempt to keep only amounts that are needed for working capital in Russia and approximately 12%~~Approximately 5% of our consolidated working capital including cash, cash equivalents and ~~short term~~short-term investments is located in Russia. We are making no new investments in Russia.

The banks have made amendments of our credit agreements to modify LIBOR and EONIA reference rates as these rates are phased out as borrowing rates. We do not plan to amend our long-term unsecured note as it matures prior to the final phase-out of LIBOR.

We are required to meet certain financial covenants associated with ~~our U.S. revolving line of~~this credit ~~and long-term debt facility.~~line. These covenants, tested quarterly, include an interest coverage ratio and a funded debt to earnings before interest, taxes, depreciation and amortization ("EBITDA") ratio. The interest coverage covenant requires that we maintain a trailing twelve-month ratio of EBITDA to interest on all obligations that is at least 3.0:1.0. The funded debt to EBITDA covenant requires that the sum of all indebtedness for borrowed money on a consolidated basis be less than three times our trailing twelve months EBITDA. Funded debt is decreased by our cash and available marketable securities not classified as long-term investments in the U.S.A. in excess of $50 million up to a maximum of $500 million. We were in compliance with all such financial covenants as of and for the three months ended September 30, ~~2022.~~2023.

The financial covenants in our loan documents may cause us to not make or to delay investments and actions that we might otherwise undertake because of limits on capital expenditures and amounts that we can borrow or lease. In the event that we do not comply with any one of these covenants, we would be in default under the loan agreement or loan agreements, which may result in acceleration of the debt, cross-defaults on other debt or a reduction in available liquidity, any of which could harm our results of operations and financial condition.

Operating activities. Net cash provided by operating activities ~~decreased~~increased by ~~$134.2~~$18.9 million to $189.9 million for the nine months ended September 30, 2023 from $171.0 million for the nine months ended September 30, 2022, ~~from $305.2 million for the nine months ended September 30, 2021,~~ primarily due to ~~an increase~~a decrease in cash used byin working capital. Our largest working capital items typically are inventory and accounts receivable. Items such as accounts payable to third parties, prepaid expenses and other current assets and accrued expenses and other liabilities are not as significant as our working capital investment in accounts receivable and inventory because of the amount of value added within IPG due to our vertically integrated structure. Accruals and payables for personnel costs including bonuses and income and other taxes payable are largely dependent on the timing of payments for those items. The ~~decrease~~increase in cash flow from operating activities in ~~2022~~2023 primarily resulted from:

•a decrease in cash used by inventory, as we moderate investment in safety stock related to supply chain disruptions for third party electronic parts and components internally manufactured by our factory in Russia;

•an increase in cash ~~used~~provided by income and other taxes payable driven by ~~the requirement to capitalize research and development expenses in the U.S and~~ the timing of estimated tax payments made and refunds received from filing tax ~~returns,~~returns; and

•~~an increase~~a decrease in cash used by accrued expenses due to ~~higher~~lower bonus payments, ~~and lower bonus accruals,~~

•partially offset by an increase in cash used by ~~inventory, including an increase~~contract liabilities, billings in ~~days inventory on hand as the company builds safety stocks for supply chain disruptions related to third party electronic parts~~excess of costs and ~~components internally manufactured~~estimated earning and accounting and legal accruals.

The increases in cash provided by ~~our factory in Russia,~~operating activities were partially offset by:

•a decrease in cash provided by net income after adjusting for non-cash operating ~~activities, partly driven by the non-cash gain on divestiture of the telecommunications transmission product lines; partially offset by,~~activities;

•an increase in cash ~~provided~~used by ~~accounts receivable, including a decrease in days sales outstanding~~prepaid expenses and other assets due to ~~increased collection efforts,~~timing of bank acceptance drafts, insurance prepayments and billings on custom systems; and

•an increase in cash ~~provided~~used by ~~prepaid expenses and other assets.~~accounts payable due to timing of payments.

Investing activities. Net cash ~~provided by~~used in investing activities was ~~$407.5~~$163.0 million for the nine months ended September 30, ~~2022~~2023 as compared to cash provided by investing activities of $407.5 million in 2022. The cash used in investing activities in 2023 related to $108.6 million of ~~$304.8~~net purchases of short-term investments and $85.3 million ~~in 2021.~~of cash used for capital expenditures; partially offset by $30.4 million of cash provided by sales of property, plant and equipment. The cash provided by investing activities in 2022 related to $441.3 million of net proceeds from short-term investments, and $52.1 million of proceeds received from the divestiture of the telecommunications transmission product lines, net of cash sold; partially offset by $84.6 million of cash used for capital expenditures. ~~The cash used in investing activities in 2021 related to $210.7 million of net purchases of short-term investments and $93.9 million of capital expenditures.~~

In ~~2022,~~2023, we expect to invest approximately $100 million to $110 million in capital expenditures, excluding acquisitions. Capital expenditures include investments in property, facilities and equipment to add capacity worldwide to support anticipated revenue growth, increase vertical integration, increase redundant manufacturing capacity for critical components and enhance research and development capabilities. The timing and extent of any capital expenditures in and between periods can have a significant effect on our cash flow. If we obtain financing for certain projects, our cash expenditures would be reduced in the year of expenditure. Many of the capital expenditure projects that we undertake have long lead times and are difficult to cancel or defer to a later period once a project has been started.

Financing activities. Net cash used in financing activities was ~~$400.9~~$176.0 million for the nine months ended September 30, ~~2022~~2023 as compared to net cash used of ~~$72.1~~$400.9 million in ~~2021.~~2022. The cash used in financing activities in 2023 primarily related to the purchase of treasury stock of $159.5 million and principal payments on our long-term borrowings of $16.0 million. The cash used in financing activities in 2022 primarily related to the purchase of treasury stock of $382.9 million, and $17.8 million of principal payments on our long-term borrowings; the purchase of non-controlling interests of $2.5 million related to the divestiture of the telecommunications transmission product lines; partially offset by, the proceeds of $2.4 million from the issuance of common stock under the employee stock purchase plan and the exercise of stock options net of amounts disbursed in relation to shares withheld to cover employee income taxes due upon the vesting and release of restricted stock units. The cash used in financing activities in 2021 related to the purchase of treasury stock of $78.1 million, $2.9 million of principal payments on our long-term borrowings and $2.6 million of payments of purchase price holdbacks from business combinations; partially offset by, proceeds of $11.4 million from the exercise of stock options net of amounts disbursed in relation to shares withheld to cover employee income taxes due upon the vesting and release of restricted stock units.borrowings.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk in the ordinary course of business, which consists primarily of interest rate risk associated with our cash and cash equivalents ~~and our debt~~ and foreign exchange rate risk.

Interest rate risk. Certain interest rates are variable and fluctuate with current market conditions. Our investments have limited exposure to market risk. We maintain a portfolio of cash, cash equivalents and short-term investments consisting primarily of bank deposits, money market funds, certificates of deposit, commercial paper, corporate bonds and U.S treasury and agency obligations. None of these investments have a maturity date in excess of one year. Because of the short-term nature of these instruments, a sudden change in market interest rates would not be expected to have a material impact on our financial condition or results of operations.

We are also exposed to market risk as a result of increases or decreases in the amount of interest expense we must pay on our ~~bank debt and~~ borrowings on our bank credit facilities. ~~Our interest obligations on our long-term debt are fixed by means of an interest rate swap agreement.~~ Although our U.S. revolving line of credit ~~and our euro credit facility~~ have variable rates, we do not believe that a 10% change in market interest rates would have a material impact on our financial position or results of operations.

Exchange rates. Due to our international operations, a significant portion of our net sales, cost of sales and operating expenses are denominated in currencies other than the U.S. dollar, principally the euro, the Russian ruble, and the Chinese yuan. Changes in the exchange rate of the U.S. dollar versus the functional currencies of our subsidiaries affect the translated value and relative level of sales and net income that we report from one period to the next. In addition, our subsidiaries may have assets or liabilities denominated in a currency other than their functional currency which results in foreign exchange transaction gains and losses due to changes in the value of the functional currency versus the currency the assets and liabilities are denominated in. The gain on foreign exchange transactions totaled $0.4 million for the three months ended September 30, 2023 compared to a gain of $0.5 million for the three months ended September 30, ~~2022 compared to a gain of $3.6 million for the three months ended September 30, 2021.~~2022. Management attempts to minimize these exposures by partially or fully off-setting foreign currency denominated assets and liabilities at our subsidiaries that operate in different functional currencies. The effectiveness of this strategy can be limited by the volume of underlying transactions at various subsidiaries and by our ability to accelerate or delay inter-company cash settlements. As a result, we are unable to create a perfect offset of the foreign currency denominated assets and liabilities. At September 30, ~~2022,~~2023, our material foreign currency exposure is net U.S. dollar denominated assets at subsidiaries where the euro or the Russian ruble is the functional currency and U.S. dollar denominated liabilities where the Chinese yuan is the functional currency. The U.S. dollar denominated assets are comprised of cash, third party receivables and inter-company receivables. The U.S. dollar denominated

~~Table of Contents~~

liabilities are comprised of inter-company payables. A 5% change in the relative exchange rate of the U.S. dollar to the euro as of September 30, ~~2022~~2023 applied to the net U.S. dollar asset balances, would result in a foreign exchange gain of $2.0 million if the U.S. dollar appreciated and a $2.1 million foreign exchange loss if the U.S. dollar depreciated. A 5% change in the relative exchange rate of the U.S. dollar to the Russian ruble as of September 30, 2022 applied to the net U.S. dollar asset balances, would result in a foreign exchange gain of $1.5$1.4 million if the U.S. dollar appreciated and a $1.5 million foreign exchange loss if the U.S. dollar depreciated. A 5% change in the relative exchange rate of the U.S. dollar to the Russian ruble as of September 30, 2023 applied to the net U.S. dollar asset balances, would result in a foreign exchange gain of $0.2 million if the U.S. dollar appreciated and a $0.2 million foreign exchange loss if

the U.S. dollar depreciated. A 5% change in the relative exchange rate of the U.S. dollar to the Chinese yuan as of September 30, ~~2022~~2023 applied to the net U.S. dollar liabilities balances, would result in a foreign exchange loss of ~~$2.4~~$1.1 million if the U.S. dollar appreciated and a ~~$2.5~~$1.1 million foreign exchange gain if the U.S. dollar depreciated. Volatility between the U.S. dollar and the currencies to which we are exposed may be increased by the COVID-19 pandemic, sanctions on the Russian government and changes in central bank policy.

In addition, we are exposed to foreign currency translation risk for those subsidiaries whose functional currency is not the U.S. dollar as changes in the value of their functional currency relative to the U.S. dollar affect the translated amounts of our assets and liabilities. Changes in the translated value of assets and liabilities due to changes in functional currency exchange rates relative to the U.S. dollar result in foreign currency translation adjustments that are a component of other comprehensive income or loss.

Foreign currency derivative instruments can also be used to hedge exposures and reduce the risks of certain foreign currency transactions; however, these instruments provide only limited protection and can carry significant cost. We have no foreign currency derivative instruments as of September 30, ~~2022.~~2023. We will continue to analyze our exposure to currency exchange rate fluctuations and may engage in financial hedging techniques in the future to attempt to minimize the effect of these potential fluctuations. Exchange rate fluctuations may adversely affect our financial results in the future.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision of our chief executive officer and our chief financial officer, our management has evaluated the effectiveness of the design and operation of our "disclosure controls and procedures" (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as of the end of the period covered by this Quarterly Report on Form 10-Q (the "Evaluation Date"). Based upon that evaluation, our chief executive officer and our chief financial officer have concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective.

Changes in Internal Controls

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act) that occurred during the quarter ended September 30, ~~2022~~2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. ~~We are continually monitoring and assessing the changes to business processes resulting from COVID-19 to ensure the design and operating effectiveness of our controls are adequate.~~
