NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(In thousands, except share and per share data)

1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation — The accompanying unaudited condensed consolidated financial statements have been prepared by IPG Photonics Corporation, or "IPG", "its" or the "Company". Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). The condensed consolidated financial statements include the Company's accounts and those of its subsidiaries. All intercompany balances have been eliminated in consolidation. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

In the opinion of the Company's management, the financial information for the interim periods presented reflects all adjustments necessary for a fair presentation of the Company's financial position, results of operations and cash flows. The results reported in these condensed consolidated financial statements are not necessarily indicative of results that may be expected for the entire year.

Accounts Receivable and Allowance for Credit Losses — The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that will not be collected. The allowance is based upon an estimate of expected credit losses over the life of outstanding receivables. The estimate involves an assessment of customer creditworthiness, historical payment experience, an assumption of future expected credit losses, and the age of outstanding receivables.

Activity related to the allowance for doubtful accounts was as follows:

	Three Months Ended March 31,
	2024		2023
Balance, beginning of period	$	1,763	$	2,639
Provision for bad debts, net of (recoveries)	93		(209)
Uncollectible accounts written off	(25)		(50)
Foreign currency translation	(14)		(17)
Balance, end of period	$	1,817	$	2,363

Comprehensive Income — Comprehensive income includes charges and credits to equity that are not the result of transactions with stockholders. Included within comprehensive income is the cumulative foreign currency translation adjustment and unrealized gains or losses on derivatives. These adjustments are accumulated within the condensed consolidated statements of comprehensive income.

Subsequent Events — The Company has considered the impact of subsequent events through the filing date of these financial statements. There were no events through the filing date of these financial statements required to be disclosed.

2. RECENT ACCOUNTING PRONOUNCEMENTS

Adopted Pronouncements — In November 2023, the FASB issued ASU No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" ("ASU 2023-07"), which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an annual and interim basis. Under the new guidance an entity is required to disclose the title and position of the chief operating decision maker ("CODM") and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The ASU also requires that an entity that has a single reportable segment provide all the disclosures required by this ASU and all existing segment disclosures in Topic 280. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted this standard during fiscal year 2024, and will start disclosing the required information in fiscal year ending December 31, 2024. The Company does not expect this standard to have a material impact.

Pronouncements Currently Under Evaluation — In December 2023, the FASB issued ASU No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" ("ASU 2023-09"), which requires an entity on an annual basis to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The guidance also requires an entity to disclose on an annual basis information about income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. The Company is evaluating the impact of this ASU and does not expect this standard will have a material impact.

3. REVENUE FROM CONTRACTS WITH CUSTOMERS

Sales are derived from products for different applications: fiber lasers, diode lasers, systems and accessories for materials processing; fiber lasers, diodes and amplifiers for advanced applications; and fiber lasers, systems and fibers for medical applications.

One of the Company's customers accounted for 21% and 14% of the Company's net accounts receivable as of March 31, 2024 and December 31, 2023, respectively.

The Company enters into contracts to sell lasers and spare parts, for which revenue is generally recognized upon shipment or delivery, depending on the terms of the contract. The Company also provides installation services and extended warranties. The Company frequently receives consideration from a customer prior to transferring goods to the customer under the terms of a sales contract. The Company records customer deposits related to these prepayments, which represent a contract liability. The 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.

4. FAIR VALUE MEASUREMENTS

The Company's financial instruments consist of cash equivalents, short-term investments, accounts receivable, accounts payable, and revolving lines of credit.

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 fair value of money market fund deposits, cash equivalent term deposits, accounts receivable, accounts payable and drawings on revolving lines of credit is reasonably close to their 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 fair value of the Company's commercial paper, corporate bonds, U.S. Treasury and agency obligations and term deposits are based on Level 2 inputs.

availability under this line was $72,289 at March 31, 2024. In addition, the Company maintains Euro lines of credit facilities with a total principal amount of €6,500 ($7,014 as of March 31, 2024), which are available to certain European subsidiaries.

10. 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 March 31, 2024 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 Condensed Consolidated Financial Statements.

11. INCOME TAXES

The effective tax rates were 28.3% and 27.8% for the three months ended March 31, 2024 and 2023, respectively. There was a net discrete tax detriment of $1,997 for the three months ended March 31, 2024 and a net discrete tax detriment of $1,972 for the three months ended March 31, 2023. The detriment in 2024 relates primarily to the increase in tax expense for equity-based compensation expense reflected in financial statement income in excess of the deductions allowed for tax purposes. This item was partially offset by a decrease in uncertain tax positions due to the conclusion of tax audits. There was a similar but smaller detriment for equity base compensation in 2023.

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 three months ended March 31, 2024 and 2023:

	Three Months Ended March 31,
	2024		2023
Balance, beginning of period	$	17,176	$	15,841
Change in prior period positions	(2,000)		42
Additions for tax positions in current period	76		—
Foreign currency translation	—		(78)
Balance, end of period	$	15,252	$	15,805

The liability for uncertain tax benefits is included in other long-term liabilities and deferred income taxes at March 31, 2024 and December 31, 2023. 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, advanced applications and communications. 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 and 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 Poland and expanded capacity in Italy 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.

On April 30, 2024, we announced that Mark Gitin has been appointed Chief Executive Officer effective June 5, 2024. Dr. Gitin will succeed Dr. Eugene Scherbakov who will remain a member of the Board of Directors and will serve as an advisor to Dr. Gitin. Dr. Gitin has more than 30 years of experience in the lasers and optics sector, most recently overseeing the Photonics Solutions Division at MKS Instruments.

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.

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 due to our manufacturing operations in Belarus. Since the start of the conflict, we have been 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. Since 2022, we have been hiring and training additional employees, expanding capacity for increased production, running additional shifts in the U.S. and 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 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 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 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 lower labor costs than the United States and Germany, with ongoing product expense reduction initiatives, higher productivity from automation, improved yields and product specifications. We are also continuing to review our operations in Russia and Belarus. For additional information regarding the risks and potential impacts of the Russia-Ukraine conflict, see “Risk Factors – The ongoing conflict between Russia and

15

Ukraine may adversely affect our business and results of operations” in Item 1A of Part I of Form 10-K for the year ended December 31, 2023.

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 December 31, 2023, we have substantially completed the restructuring program in Russia.

Sales to third-parties in Russia were approximately 4% of our revenue for the first quarter of 2024, and 3% for the full year ended December 31, 2023. 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 $3.8 million for the three months ended March 31, 2024 and $15.8 million for the full year ended December 31, 2023.

At March 31, 2024, we had working capital excluding cash and cash equivalents of $29.1 million in Russia of which $22.2 million is inventory. We had $73.6 million of cash and cash equivalents in Russia. The net asset value of our Russian subsidiary was $104.5 million. In addition to the impairment charges referenced above, the net value of assets in Russia has been reduced by $141.6 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 other comprehensive loss that is currently in the equity section of 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 $30.6 million at March 31, 2024, and we had working capital excluding cash of $3.9 million in Belarus of which $3.8 million is inventory. In addition, we had $3.5 million of cash in Belarus. If additional sanctions are imposed on Belarus or Belarus places restrictions on our operations there, it could trigger an asset impairment evaluation and may result in impairment charges in the future.

Our Board of Directors has been monitoring and continues to assess and monitor risks to our business associated with the Russia-Ukraine conflict and our Russian and Belarus operations. Our Directors request and receive management reports from management regarding our Russian and Belarus operations, contingency planning and execution, and impacts on our business at

its quarterly and special meetings.

Supply Chain. Because of disruptions to our supply chain caused by the COVID-19 pandemic and Russia-Ukraine related sanctions, we increased our inventory safety stocks and placed non-cancellable orders for long lead time items. These caused our inventory levels and our days inventory on hand to increase. Our ability to reduce inventory will depend on sales volume and demand for the items we have on stock. If inventory on hand becomes excess or obsolete, our inventory reserves may increase. We may also be affected by changes in freight costs as a result of other global supply chain disruptions that may occur from time to time.

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 90% of our revenues for both the first quarter of 2024 and the full fiscal year of 2023 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.

16

In response to inflation in recent years, some global central banks have adopted less accommodating monetary policy and have increased benchmark interest rates in several major global economies. The increase in interest rates is intended to dampen demand that could lead to regional or global recession that may reduce demand for our products. In addition, an increase in interest rates would increase the cost of equipment financed with leases or debt. If inflation starts to moderate in 2024, global central banks may adopt more accommodating monetary policy and reduce benchmark interest rates.

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 and pandemics to the extent that they affect macroeconomic conditions, global supply chains or individual IPG locations.

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 welding and 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 can broadly affect the demand for capital equipment including machine tools and industrial lasers, and competition from other fiber laser manufacturers.

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;

•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;

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

•Our gross margin from products on new manufacturing lines can be lower due to production inefficiencies and high scrap costs.

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

17

advantageous or leverage our existing technology base and leadership, our current gross margin levels may not be maintained. 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.

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 $12.8 million and $12.1 million for the three months ended March 31, 2024 and 2023, 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, litigation and project related consulting expenses.

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.

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 have long-lived assets in Belarus with a carrying value of $30.6 million. If sanctions increase or if the geopolitical situation changes such that we can no longer use Belarus as a source of supply for our laser cabinets and other mechanical components, we may need to evaluate those assets for impairment, 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. and Germany) also affects our costs and earnings. Certain currencies experiencing significant exchange rate fluctuations like the euro, the Russian ruble, the Chinese yuan and Japanese yen have had and could have an additional significant impact on our sales, costs and earnings. For the quarter ended March 31, 2024, the foreign exchange loss was primarily created by the depreciation of the Chinese yuan as compared to the U.S. dollar. 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. Our ability to adjust the foreign currency selling prices of products in response to changes in

18

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 13% for the three months ended March 31, 2024 and 13%, and 15% for the full years 2023 and 2022, respectively. One of our customers accounted for 21% and 14% of our net accounts receivable at March 31, 2024 and December 31, 2023, 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.

Results of Operations for the Three Months Ended March 31, 2024 Compared to the Three Months Ended March 31, 2023

Net sales. Net sales decreased by $95.2 million, or 27.4%, to $252.0 million for the three months ended March 31, 2024 from $347.2 million for the three months ended March 31, 2023.

Materials processing

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

•High power CW laser sales decreased due to lower sales for cutting and welding applications. Within cutting applications, the decrease in sales was attributable softer industrial demand and inventory management by OEM customers while welding was primarily impacted by a slowdown in the e-mobility investments.

•Medium power CW laser sales increased driven by higher demand in additive manufacturing applications.

•Pulsed laser sales, including high power pulsed lasers, decreased due to lower sales for solar cell manufacturing, marking and engraving, and foil cutting applications.

•QCW laser sales increased driven by higher demand in fine processing for consumer electronics applications.

•Laser and non-laser systems sales declined due to lower demand for LightWELD.

Other Applications

Sales from other applications decreased due to decreased demand for lasers used in advanced applications and medical procedures applications.

Cost of sales and gross margin. Cost of sales decreased by $45.7 million, or 22.8%, to $154.5 million for the three months ended March 31, 2024 from $200.2 million for the three months ended March 31, 2023. Our gross margin decreased to 38.7% for the three months ended March 31, 2024 from 42.3% for the three months ended March 31, 2023. The decrease in gross margin was driven by an increase in unabsorbed manufacturing costs and an increase in inventory provisions as a percentage of sales. The decrease in gross margin was partially offset by a decrease in cost of product sold due to product mix and shipping costs and tariffs, 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 as compared to our sales which are predominantly denominated in foreign currencies.

Sales and marketing expense. Sales and marketing expense increased by $1.9 million, or 9.0%, to $23.0 million for the three months ended March 31, 2024 compared with $21.1 million for the three months ended March 31, 2023. The increase is due to higher personnel and related costs and premises costs. As a percentage of sales, sales and marketing expense increased to 9.1% from 6.1% for the three months ended March 31, 2024 and 2023, respectively.

Research and development expense. Research and development expense increased by $6.6 million, or 28.9%, to $29.4 million for the three months ended March 31, 2024, compared to $22.8 million for the three months ended March 31, 2023. The increase is due to higher personnel and related costs, premises costs and expense for materials used for research and development projects. As a percentage of sales, research and development expense increased to 11.7% for the three months ended March 31, 2024 from 6.6% for the three months ended March 31, 2023.

20

General and administrative expense. General and administrative expense increased by $1.1 million, or 3.7%, to $31.2 million for the three months ended March 31, 2024 from $30.1 million for the three months ended March 31, 2023. The increase was due to an increase in expenses related to information systems, premises and accounting costs, partially offset by lower personnel and related costs. As a percentage of sales, general and administrative expense increased to 12.4% from 8.7% for the three months ended March 31, 2024 and 2023, respectively.

Gain on sale of assets. The gain on sale of assets of $6.8 million for the three months ended March 31, 2024 was related to the sales of a building in the U.S. and a building in the U.K.

Effect of exchange rates on net sales, gross profit and operating expenses. If exchange rates relative to the U.S. dollar had been the same as one year ago, which were on average euro 0.93, Russian ruble 73, Japanese yen 132 and Chinese yuan 6.84, respectively, we estimate that net sales for the three months ended March 31, 2024 would have been $7.8 million higher, gross profit would have been $4.7 million higher and total operating expenses would have been $1.9 million higher.

Loss on foreign exchange. We incurred a foreign exchange transaction loss of $1.7 million for the three months ended March 31, 2024 as compared to a $2.7 million gain for the three months ended March 31, 2023. 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 foreign exchange loss for the three months ended March 31, 2024 was primarily attributable to a loss related to the depreciation of the Chinese yuan as compared to the U.S. dollar.

Interest income, net. Interest income, net was $14.2 million for the three months ended March 31, 2024 as compared to $7.5 million of income for three months ended March 31, 2023. The change in interest income, net was due to an increase in yields on cash equivalents and short term investments that resulted from higher market interest rates as compared to prior year rates.

Provision for income taxes. Provision for income taxes was $9.5 million for the three months ended March 31, 2024 compared to $23.2 million for the three months ended March 31, 2023, representing an effective tax rate of 28.3% and 27.8% for the three months ended March 31, 2024 and 2023, respectively. The decrease in tax expense was primarily due to a decrease income before provision for income taxes for 2024 as compared to 2023. There were net discrete tax detriments of $2.0 million for the three months ended March 31, 2024 and net discrete detriment of $2.0 million for the three months ended March 31, 2023. Both 2024 and 2023 discrete items included an increase in tax expense from equity-based compensation expense reflected in financial statement income in excess of the deductions allowed for tax purposes. However, the 2024 discrete tax detriment from equity-based compensation was partially offset by a decrease in uncertain tax positions due the conclusion of tax audits.

Net income attributable to IPG Photonics Corporation. Net income attributable to IPG Photonics Corporation decreased by $36.0 million to $24.1 million for the three months ended March 31, 2024 compared to $60.1 million for the three months ended March 31, 2023. Net income attributable to IPG Photonics Corporation as a percentage of our net sales decreased by 7.7 percentage points to 9.6% for the three months ended March 31, 2024 from 17.3% for the three months ended March 31, 2023 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 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 our level of sales, the impact of the economic environment on our growth, 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. 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 March 31, 2024, we had no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on our consolidated financial condition, results of operations, liquidity, capital expenditures or capital resources.

21

Included in cash and cash equivalents are $73.6 million of cash and cash equivalents located in Russia, and $3.5 million of cash and cash equivalents located in Belarus, as of March 31, 2024. Cash and 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. Approximately 6% of our consolidated working capital including cash, cash equivalents and short-term investments is located in Russia. We are making no new investments in Russia.

The following table presents our principal sources of liquidity:

	March 31,		December 31,
	2024		2023
	(In thousands)
Cash and cash equivalents	$	496,452	$	514,674
Short-term investments	643,655		662,807
Unused credit lines and overdraft facilities	77,729		78,506
Working capital (excluding cash, cash equivalents and short-term investments)	497,385		522,312

Short-term investments at March 31, 2024 consist of liquid investments including commercial paper, corporate bonds, U.S. Treasury and agency obligations and term deposits with original maturities of greater than three months but less than one year. See Note 4, "Fair Value Measurements" in the notes to the condensed consolidated financial statements for further information about our short-term investments.

The following table details our line-of-credit facilities as of March 31, 2024: 

Description	Total Facility	Interest Rate	Maturity	Security
U.S. Revolving Line of Credit (1)	$75.0 million	BSBY plus 0.8% to 1.2%, depending on our performance	April 2025	Unsecured
Euro Credit Facility (Germany) (2)	Euro 5.0 million ($5.4 million)	€STR rate plus 0.97%	December 2028	Unsecured, guaranteed by parent company
Euro Facility (3)	Euro 1.5 million ($1.6 million)	Euribor plus 1.25%	June 2024	Common pool of assets of Italian subsidiary

(1) This facility is available to certain foreign subsidiaries in their respective local currencies. At March 31, 2024, there were no amounts drawn on this line; however, there were $2.7 million of guarantees issued against the line which reduces total availability.

(2) This facility is available to certain foreign subsidiaries in their respective local currencies. At March 31, 2024, there were no amounts drawn on this line; however, there were $1.6 million of guarantees issued against the line which reduces total availability.

(3) At March 31, 2024, there were no drawings.

At March 31, 2024, our committed credit line is with Bank of America N.A. in the amount of $75.0 million and it is not syndicated. We are required to meet certain financial covenants associated with this credit 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 March 31, 2024.

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.

See Note 9, "Financing Arrangements" in the notes to the condensed consolidated financial statements for further information about our facilities.

The following table presents cash flow activities:

	Three Months Ended March 31,
	2024		2023
	(In thousands)
Cash provided by operating activities	$	54,596	$	37,280
Cash provided by (used in) investing activities	23,736		(96,018)
Cash used in financing activities	(90,774)		(117,236)

Operating activities. Net cash provided by operating activities increased by $17.3 million to $54.6 million for the three months ended March 31, 2024 from $37.3 million for the three months ended March 31, 2023, primarily due to an increase in cash provided by 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 increase in cash flow from operating activities in 2024 primarily resulted from:

•an increase in cash provided by accounts receivable due to timing of collection;

•an increase in cash provided by inventory, as we moderate investment in safety stock related to supply chain disruptions for third party electronic parts and internally manufactured components;

•a decrease in cash used by income and other taxes payable driven by lower taxable income and the timing of estimated tax payments made and refunds received from filing tax returns;

•an increase in cash provided by accounts payable due to timing of payments; and

•a decrease in cash used by prepaid expenses and other assets due to timing of bank acceptance drafts and billings on custom systems.

The increases in cash provided by operating activities were partially offset by:

•a decrease in cash provided by net income after adjusting for non-cash operating activities, mainly due to lower sales; and

•an increase in cash used by accrued expenses due to an increase in cash used by contract liabilities, partially offset by lower accrual related to personnel payments.

Investing activities. Net cash provided by investing activities was $23.7 million for the three months ended March 31, 2024 as compared to cash used in investing activities of $96.0 million in 2023. The cash provided by investing activities in 2024 related to $26.4 million of net proceeds of short-term investments and $25.3 million of cash provided by sales of property, plant and equipment; partially offset by $28.1 million of cash used for capital expenditures. The cash used in investing activities in 2023 related to $64.3 million of net purchases of short-term investments and $33.4 million of cash used for capital expenditures.

In 2024, we expect to invest approximately $120 million to $130 million in capital expenditures, net of asset divestitures. Capital expenditures include investments in property, facilities and equipment to replace capacity in Russia that we can no longer use to manufacture optical components and finished goods and upgrade or replace equipment at other facilities that is beyond its useful life. Capital expenditures also include investments to 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. We intend to finance our capital expenditures with existing cash, cash equivalents and short term investments as well as with cash generated from operations.

Financing activities. Net cash used in financing activities was $90.8 million for the three months ended March 31, 2024 as compared to net cash used of $117.2 million in 2023. The cash used in financing activities in 2024 primarily related to the purchase of treasury stock of $89.6 million. The cash used in financing activities in 2023 primarily related to the purchase of treasury stock of $113.1 million and the net cash outflow of $3.8 million from the issuance of common stock under the

23

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.

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 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 borrowings on our bank credit facilities. Although our U.S. revolving line of credit 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 loss on foreign exchange transactions totaled $1.7 million for the three months ended March 31, 2024 compared to a gain of $2.7 million for the three months ended March 31, 2023. 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.

24

At March 31, 2024, 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 net U.S. dollar denominated assets are comprised of cash, third party receivables and inter-company receivables offset by third party and inter-company U.S. dollar denominated payables. The U.S. dollar denominated 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 March 31, 2024 applied to the net U.S. dollar asset balances, would result in a foreign exchange gain of $1.0 million if the U.S. dollar appreciated and a $1.0 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 March 31, 2024 applied to the net U.S. dollar asset balances, would result in a foreign exchange gain of $0.1 million if the U.S. dollar appreciated and a $0.1 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 Chinese yuan as of March 31, 2024 applied to the net U.S. dollar liabilities balances, would result in a foreign exchange loss of $0.9 million if the U.S. dollar appreciated and a $0.9 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, primarily, related to interest rates..

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 on the condensed consolidated statements of comprehensive income.

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 March 31, 2024. 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 March 31, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
