The computation of diluted weighted average common shares excludes options to purchase 198,000 shares and 14,000 shares for the three months ended June 30, 2013 and 2012 , respectively, and 208,000 shares and 14,000 shares for the six months ended June 30, 2013 and 2012 , respectively, because the effect would be anti-dilutive.

The Company computes net income per share in accordance with ASC 260- Earnings Per Share . Under the provisions of ASC 260, the Company is required to present basic and diluted earnings per share information separately for each class of equity instruments that participate in any income distribution with primary equity instruments. The Company calculates earnings per share in periods where a class of common stock was redeemable for other than fair value through the application of the two-class method. Until June 29, 2012, the Company had redeemable noncontrolling interests reported in the accompanying consolidated financial statements related to a 22.5% minority interest of the Company's Russian subsidiary, NTO IRE-Polus.

7. DERIVATIVE FINANCIAL INSTRUMENTS

The Company’s primary market exposures are to interest rates and foreign exchange rates. The Company uses certain derivative financial instruments to help manage these exposures. The Company executes these instruments with financial institutions it judges to be credit-worthy. The Company does not hold or issue derivative financial instruments for trading or speculative purposes.

The Company recognizes all derivative financial instruments as either assets or liabilities at fair value in the consolidated balance sheets. The Company has used foreign currency forward contracts as cash flow hedges of forecasted intercompany settlements denominated in foreign currencies of major industrial countries. The Company has no outstanding foreign currency forward contracts. The Company has interest rate swaps that are classified as a cash flow hedge of its variable rate debt. The Company has no derivatives that are not accounted for as a hedging instrument.

Cash flow hedges – The Company’s cash flow hedges are interest rate swaps under which it pays fixed rates of interest. The fair value amounts in the consolidated balance sheet were:



	Notional Amounts ¹				Other Assets				Other Long-Term Liabilities
	June 30,		December 31,		June 30,		December 31,		June 30,		December 31,
	2013		2012		2013		2012		2013		2012

8. FAIR VALUE MEASUREMENTS

The Company’s financial instruments consist of cash equivalents, accounts receivable, auction rate securities, accounts payable, drawings on revolving lines of credit, long-term debt and certain derivative instruments.

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 carrying amounts of cash equivalents, accounts receivable, accounts payable and drawings on revolving lines of credit are considered reasonable estimates of their fair market value, due to the short maturity of these instruments or as a result of the competitive market interest rates, which have been negotiated. If measured at fair value, accounts receivable and accounts payable would be classified as Level 3 and drawings on the revolving lines of credit would be classified as Level 2.

The following table presents information about the Company’s cash equivalents and assets and liabilities measured at fair value:

The fair value of the auction rate securities considered prices observed in inactive secondary markets for the securities held by the Company.

The fair value of accrued contingent consideration incurred was determined using an income approach at the acquisition date and reporting date. That approach is based on significant inputs that are not observable in the market. Key assumptions include assessing the probability of meeting certain milestones required to earn the contingent consideration.

During the three months ended June 30, 2013, the Company reduced the fair value of the accrued contingent purchase consideration associated with a 2012 purchase of a manufacturer of laser-based systems as of June 30, 2013 by $2,463 as management assessed that there was no possibility that any earn-out amounts included in the purchase agreement with the former owners would be achieved (see Note 9). The adjustment was included in total other (expense) income, net.

During the first quarter of 2012, the Company determined a final payment of contingent consideration and other related matters in association with the purchase of a technology company in 2010, increased the liability by $987 and reclassed the revised obligation to accrued expenses. The adjustment was included in total other (expense) income, net. As the payment was then fixed, it was no longer measured at its fair value.

Also, during the six months ended June 30, 2012, the Company terminated the warrant held by Rusnano as part of the redemption of Rusnano's redeemable noncontrolling interest for its fair value of $77 .

Amortization expense for the three months ended June 30, 2013 and 2012 was $646 and $546 , respectively. Amortization expense for the six months ended June 30, 2013 and 2012 was $1,109 and $1,097 , respectively.The estimated future amortization expense for intangibles for the remainder of 2013 and subsequent years is as follows:



2013	2014	2015	2016	2017	Thereafter	Total
$1,171	$2,185	$1,653	$1,443	$1,418	$3,086	$10,956

In accordance with ASC 350- Intangibles-Goodwill and Other , the Company assesses the impairment of its long-lived assets including its definite-lived intangible assets and goodwill, at least annually for goodwill, and whenever changes in events or circumstances indicate that the carrying value of such assets may not be recoverable. During each reporting period, the Company assesses for factors that may be present which would cause an impairment review.

During the second quarter of 2013, the Company undertook an impairment analysis of long-lived assets and goodwill related to IPG Microsystems ("IPGM"). The Company undertook the analysis because of certain qualitative factors including a decline in sales and bookings due to underlying weakness in the markets IPGM serves.

The Company performed an impairment analysis to assess whether there was permanent impairment of long-lived assets of IPGM including identifiable intangibles included in the table above using the guidance in ASU 360-10-35. The Company concluded that no impairment existed as the undiscounted cash flows from IPGM are forecasted to be greater than the carrying value of identified long-lived assets as at June 30, 2013 .

The Company carried out the two-step goodwill impairment test in accordance with the provisions of ASU 350-20-35. That analysis indicated that the fair value of IPGM, based on a discounted cash flow analysis, was less than the carrying value. The implied value of goodwill, as measured in step 2, was zero. Accordingly, the Company adjusted the value of goodwill associated with IPGM to $0 . The adjustment was included in total other (expense) income, net.

10. PRODUCT WARRANTIES

The Company typically provides one to three -year parts and service warranties on lasers and amplifiers. Most of the Company’s sales offices provide support to customers in their respective geographic areas. Warranty reserves have generally been sufficient to cover product warranty repair and replacement costs. The following table summarizes product warranty activity recorded during the six months ended June 30, 2013 and 2012 .



	2013			2012
Balance at January 1	$	10,714		$	8,631
Provision for warranty accrual	4,984			3,699
Warranty claims and other reductions	(2,586		)	(2,946		)
Foreign currency translation	(234		)	(224		)
Balance at June 30	$	12,878		$	9,160

Accrued warranty reported in the accompanying consolidated financial statements as of June 30, 2013 and December 31, 2012 consist of $8,344 and $7,838 in accrued expenses and other liabilities and $4,534 and $2,876 in other long-term liabilities, respectively.

11. INCOME TAXES

A reconciliation of the total amounts of unrecognized tax benefits is as follows:



	2013			2012
Balance at January 1	$	5,392		$	4,509
Reductions of prior period positions	(63		)	—
Additions for tax positions in prior period	—			—
Additions for tax positions in current period	313			18
Balance at June 30	$	5,642		$	4,527

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.

12. COMMITMENTS AND CONTINGENCIES

From time to time, the Company may be involved in disputes and legal proceedings in the ordinary course of its business. These proceedings may include allegations of infringement of intellectual property, commercial disputes and employment matters. In August 2013, the Company was sued for misappropriation of certain trade secrets, unfair trade practices, and correction of inventorship on a patent owned by the Company related to beam couplers and beam switches. The plaintiff seeks damages in an unspecified amount, double damages for misappropriation of trade secrets and treble damages for unfair trade practices. The Company has not filed a response. The Company intends to vigorously defend the claims. At this time, no loss is deemed probable and no amounts have been accrued in respect of this contingency.

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

You should read the following discussion in conjunction with our 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 and manufacture a broad line of high-performance fiber lasers, fiber amplifiers and diode lasers that are used in numerous applications, primarily in materials processing. 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.

We are vertically integrated such that we design and manufacture most of our key components used in our finished products, from semiconductor diodes to optical fiber preforms, finished fiber lasers and amplifiers. We also manufacture certain complementary products used with our lasers, including optical delivery cables, fiber couplers, beam switches, optical heads and chillers. In addition, we offer laser-based systems for certain markets and applications.

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.

Net sales. We derive net sales primarily from the sale of fiber lasers and amplifiers. We also sell diode lasers, communications systems, laser systems and complementary products. We sell our products through our direct sales organization and our network of distributors and sales representatives, as well as system integrators. We sell our products to OEMs that supply materials processing laser systems, communications systems and medical laser systems to end users. We also sell our products to end users that build their own systems which incorporate our products or use our products as an energy or light source. Our scientists and engineers work closely with OEMs, systems integrators and end users to analyze their system requirements and match appropriate fiber laser or amplifier specifications. 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.

Sales of our products generally are recognized upon shipment, provided that no obligations remain and collection of the receivable is reasonably assured. Our sales typically are made on a purchase order basis rather than through long-term purchase commitments.

We develop our products to standard specifications and use a common set of components within our product architectures. Our major products are based upon a common technology platform. We continually enhance these and other products by improving their components and developing new components and new product designs.

The average selling prices of our products generally decrease as the products mature. These decreases result from factors such as decreased manufacturing costs and increases in unit volumes, increased competition, the introduction of new products and market share considerations. In the past, we have lowered our 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 purchase multiple units.

Gross margin . Our total gross margin in any period can be significantly affected by total net sales in any period, by product mix, that is, the percentage of our revenue in the period that is attributable to higher or lower-power products, by sales mix between OEM customers and other customers, by mix of sales in different geographies and by other factors, some of which are not under our control.

Our product mix affects our margins because the selling price per watt is generally higher for low, mid-power devices and certain specialty products than for high-power devices sold in large volumes. The overall cost of high-power lasers may be partially offset by improved absorption of fixed overhead costs associated with sales of larger volumes of higher-power products because they use a greater number of optical components and drive economies of scale in manufacturing. Also, the profit margins on systems can be lower than margins for our laser and amplifier sources, depending on the configuration, volume and competitive forces, among other factors.

The mix of sales between OEM customers and other customers can affect gross margin because we provide sales price discounts on products based on the number of units ordered. As the number of OEM customers increases and the number of

Table of Contents

units ordered increases, the average sales price per unit will be reduced. We expect that the impact of reduced sales price per unit will be offset by the manufacturing efficiency provided by high unit volume orders, but the timing and extent of achieving these efficiencies may not always match the mix of sales in any given time period.

The mix of sales between geographies can effect gross margin primarily due to the affect of pass through costs like freight and duty. Pass through costs do not generally have a mark up so a higher proportion of of pass through cost to total selling price in one geography will yield a lower gross margin than another geography with lower pass through costs.

A high proportion of our costs is fixed so they are generally difficult or slow 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 or inventory write-downs, our gross margins will be negatively affected.

We also regularly review our inventory for items that are slow-moving, have been rendered obsolete or determined to be excess. Any write-off of such slow-moving, obsolete or excess inventory affects our gross margins. For example, we recorded provisions for inventory totaling $2.0 million and $1.8 million for the three months ended June 30, 2013 and 2012 , $3.6 million and $3.6 million for the six months ended June 30, 2013 and 2012 respectively and $8.2 million, $6.1 million and $2.7 million for the years ended December 31, 2012, 2011 and 2010, respectively.

Sales and marketing expense. We expect to continue to expand our worldwide direct sales organization, build and expand applications centers, hire additional personnel involved in marketing in our existing and new geographic locations, increase the number of units for demonstration purposes and otherwise increase expenditures on sales and marketing activities in order to support the growth in our net sales. As such, we expect that our sales and marketing expenses will increase in the aggregate.

Research and development expense. We plan to continue to invest in research and development to improve our existing components and products and develop new components, products and systems. The amount of research and development expense we incur may vary from period to period. In general, if net sales continue to increase we expect research and development expense to increase in the aggregate.

General and administrative expense. We expect our general and administrative expenses to increase as we continue to invest in systems and resources to support our worldwide operations. Legal expenses vary from quarter to quarter based primarily upon the level of litigation and transaction activities.

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 year to year. Net sales derived from our five largest customers as a percentage of our net sales were 22% for the six months ended June 30, 2013 and 16%, 17% and 19% for the full years 2012, 2011 and 2010, 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. If any of our significant customers were to substantially reduce their purchases from us, our results would be adversely affected.

Results of Operations for the three months ended June 30, 2013 compared to the three months ended June 30, 2012

Net sales. Net sales increased by $30.2 million , or 21.9% , to $168.2 million for the three months ended June 30, 2013 from $137.9 million for the three months ended June 30, 2012 .

addition, new welding processes using fiber lasers have been developed, increasing sales of lasers for this application, which are replacing traditional laser and non-laser welding technologies. We also increased sales of QCW and pulsed lasers used for cutting and welding thin sheet metal and for marking and engraving applications. Both of these applications increased because of higher demand in consumer electronics applications. The decrease in other applications sales relates primarily to a decrease in sales of telecommunications related product slightly offset by increases in lasers sold for advanced applications.

Cost of sales and gross margin. Cost of sales increased by $15.2 million , or 24.2% , to $78.2 million for the three months ended June 30, 2013 from $63.0 million for the three months ended June 30, 2012 . Our gross margin decreased to 53.5% for the three months ended June 30, 2013 from 54.3% for the three months ended June 30, 2012 . Gross margin decreased due to geographical mix of sales and an increase in sales volume to OEM customers which earn volume sales discounts. Additionally, gross margin was negatively impacted by 0.8 percentage points by an acquisition made in the fourth quarter of 2012 due to sales of inventory which was written up to fair value from cost at acquisition date and due to lower absorption of manufacturing costs.

Sales and marketing expense. Sales and marketing expense increased by $0.9 million , or 16.9% , to $6.8 million for the three months ended June 30, 2013 from $5.9 million for the three months ended June 30, 2012 , primarily as a result of increases in personnel costs and depreciation of product used for demonstration purposes. As a percentage of sales, sales and marketing expense decreased to 4.1% for the three months ended June 30, 2013 from 4.2% for the three months ended June 30, 2012 .

Research and development expense. Research and development expense increased by $3.3 million , or 45.0% , to $10.5 million for the three months ended June 30, 2013 , compared to $7.2 million for the three months ended June 30, 2012 , primarily as a result of increases in personnel costs and costs of material used for research and development. Included in the increase are $1.3 million of research and development costs associated with acquisitions made in the third quarter of 2012 and first quarter of 2013. Research and development continues to focus on developing new products at different wavelengths including ultra-violet ("UV"), green and mid-infrared, new pulsed products, enhancing the performance of our internally manufactured components, refining production processes to improve manufacturing yields, developing new accessories and achieving higher output powers. As a percentage of sales, research and development expense increased to 6.2% for the three months ended June 30, 2013 from 5.2% for the three months ended June 30, 2012 .

General and administrative expense. General and administrative expense increased by $4.1 million , or 46.9% , to $12.8 million for the three months ended June 30, 2013 from $8.7 million for the three months ended June 30, 2012 , primarily as a result of increased personnel, travel and premises costs as well as $0.8 million of general and administrative cost associated with acquisitions made in the fourth quarter of 2012 and first quarter of 2013 . As a percentage of sales, general and administrative expense increased to 7.6% for the three months ended June 30, 2013 from 6.3% for the three months ended June 30, 2012 .

Effect of exchange rates on net sales, gross profit and operating expenses. We estimate that, if exchange rates had been the same as one year ago, net sales for the three months ended June 30, 2013 would have been $0.1 million higher, gross profit would have been approximately the same and total operating expenses would have been $0.2 million higher.

Gain on foreign exchange. We incurred a foreign exchange gain of $0.1 million for the three months ended June 30, 2013 as compared to $3.4 million gain for the three months ended June 30, 2012 . The change is primarily attributable to the changes of the U.S. Dollar against the Euro, Russian Ruble and Chinese Yuan.

Interest (expense) income, net. Interest (expense) income, net decreased to $0.1 million of expense for the three months ended June 30, 2013 compared to $0.6 million of income for the three months ended June 30, 2012 . The decrease is the result of lower interest bearing deposits as compared to the prior period.

Other expense, net. Other expense, net increased slightly to $0.2 million of expense for the three months ended June 30, 2013 compared to $0.1 million of expense for the three months ended June 30, 2012 . $2.9 million goodwill impairment charge partially offset by a $2.5 million reduction in contingent consideration related to a 2012 acquisition are included for the three months ended June 30, 2013 .

Provision for income taxes. Provision for income taxes was $17.9 million for the three months ended June 30, 2013 compared to $17.1 million for the three months ended June 30, 2012 , representing an effective tax rates of 30.0% and 30.1% for the three months ended June 30, 2013 and 2012 , respectively. The increase in the provision for income taxes was primarily the result of increased income before income taxes.

Net income attributable to IPG Photonics Corporation. Net income attributable to IPG Photonics Corporation increased by $4.0 million to $41.7 million for the three months ended June 30, 2013 compared to $37.7 million for the three months

ended June 30, 2012 . Net income attributable to IPG Photonics Corporation as a percentage of our net sales decreased by 2.6 percentage points to 24.8% for the three months ended June 30, 2013 from 27.4% for the three months ended June 30, 2012 due to the factors described above.

Results of Operations for the six months ended June 30, 2013 compared to the six months ended June 30, 2012

Net sales. Net sales increased by $48.9 million , or 18.7% , to $310.0 million for the six months ended June 30, 2013 from $261.1 million for the six months ended June 30, 2012 .

Sales for materials processing applications increased primarily due to higher sales of high-power, medium-power and QCW lasers used in cutting and welding applications and pulsed lasers used in marking and engraving applications. We continue to see increased acceptance of the advantages of fiber laser technology. A growing number of OEM customers have developed cutting systems that use our high-power lasers and sales of these systems are gaining sales from gas laser systems. In addition, new welding processes using fiber lasers have been developed, increasing sales of lasers for this application, which are replacing traditional laser and non-laser welding technologies. We also increased sales of QCW and pulsed lasers used for cutting and welding thin sheet metal and for marking and engraving applications. Both of these applications increased because of higher demand in consumer electronics applications. The decrease in other applications sales relates primarily to a decrease in sales of telecommunications related product slightly offset by increases in lasers sold for advanced applications. Orders for certain advanced applications can be uneven and of high unit value so that they can both benefit and impact sales depending on their timing.

Cost of sales and gross margin. Cost of sales increased by $27.0 million , or 22.9% , to $144.5 million for the six months ended June 30, 2013 from $117.5 million for the six months ended June 30, 2012 . Our gross margin decreased to 53.4% from 55.0% for the six months ended June 30, 2013 and 2012, respectively. Gross margin decreased due to product and geographical mix of sales and an increase in sales volume to OEM customers which earn volume sales discounts. Product mix reduced gross margin due to lower sales of high brightness lasers in the six months ended June 30, 2013 . High brightness lasers have a higher average selling price per watt than other products. Additionally, product and gross margin was negatively impacted by 0.6 percentage points by an acquisitions made in the fourth quarter of 2012 due to sales of inventory which was written up to fair value from cost at acquisition date and due to lower absorption of manufacturing costs.

Sales and marketing expense. Sales and marketing expense increased by $1.7 million , or 15.7% , to $12.7 million for the six months ended June 30, 2013 from $11.0 million for the six months ended June 30, 2012 , primarily as a result of an increase in salaries and benefits and an increase in expenses for advertising and trade shows. As a percentage of sales, sales and marketing expense decreased slightly to 4.1% for the six months ended June 30, 2013 from 4.2% for the six months ended June 30, 2012 .

Research and development expense. Research and development expense increased by $4.9 million , or 34.2% , to $19.3 million for the six months ended June 30, 2013 , compared to $14.4 million for the six months ended June 30, 2012 , primarily due to an increase in personnel costs. Included in the increase are $1.7 million of research and development costs associated with companies which were acquired in the third quarter of 2012 and first quarter of 2013. Research and development continues to focus on developing new products at different wavelengths including UV, green and mid-infrared, new pulsed products, improving the electrical efficiency of high power products, enhancing the performance of our internally manufactured components, refining production processes to improve manufacturing yields, developing new accessories and achieving higher output powers. As a percentage of sales, research and development expense increased to 6.2% for the six months ended June 30, 2013 from 5.5% for the six months ended June 30, 2012 .

General and administrative expense. General and administrative expense increased by $5.9 million , or 31.9% , to $24.6 million for the six months ended June 30, 2013 from $18.7 million for the six months ended June 30, 2012 , primarily due to increased salaries and benefits, travel and premises expenses. General and administrative costs increased $1.6 million due to the additions of general and administrative costs for companies acquired in the fourth quarter of 2012 and the first quarter if 2013. As a percentage of sales, general and administrative expense increased to 7.9% for the six months ended June 30, 2013 from 7.2% for the six months ended June 30, 2012 .

Effect of exchange rates on net sales, gross profit and operating expenses. We estimate that, if exchange rates had been the same as one year ago, net sales for the six months ended June 30, 2013 would have been $1.7 million higher, gross profit would have been $1.0 million higher and total operating expenses would have been $0.3 million higher.

Gain on foreign exchange. We incurred a foreign exchange gain of $0.6 million for the six months ended June 30, 2013 as compared to $2.1 million gain for the six months ended June 30, 2012 . The change is primarily attributable to the changes of the U.S. Dollar against the Euro, Russian Ruble, Chinese Yuan and Korean Won.

Interest (expense) income, net. Interest (expense) income, net decreased to $0.1 million of expense for the six months ended June 30, 2013 compared to $0.5 million of income for the six months ended June 30, 2012 . The increase of income is the result of increases in interest bearing deposits during the period. The decrease is the result of lower interest bearing deposits as compared to the prior period.

Other expense, net. Other expense, net decreased to $0.2 million of expense for the six months ended June 30, 2013 compared to $1.2 million of expense for the six months ended June 30, 2012 . $2.9 million goodwill impairment charge partially offset by a $2.5 million reduction in contingent consideration related to a 2012 acquisition are included for the six months ended June 30, 2013 . $1.1 million for the six months ended June 30, 2012 related to final payments on a contingent consideration agreement from a prior acquisition.

Provision for income taxes. Provision for income taxes was $32.4 million for the six months ended June 30, 2013 compared to $30.5 million for the six months ended June 30, 2012 , representing an effective tax rate of 29.7% and 30.3% for the six months ended June 30, 2013 and 2012 , respectively. The increase in the provision for income taxes was primarily the result of increased income before provision for income taxes. The decrease in effective rate was due primarily to the mix of income earned in various tax jurisdictions as well as the benefit of 2012 research and development credits included in the American Taxpayer Relief Act of 2012 (the “Act”) which was signed into law on January 2, 2013. Because a change in tax law is accounted for in the period of enactment, certain provisions of the Act benefiting our 2012 U.S. federal taxes, including the research and experimentation credit, could not be recognized in our 2012 financial results and instead were reflected in our first quarter 2013 financial results.

Net income attributable to IPG Photonics Corporation. Net income attributable to IPG Photonics Corporation increased by $9.1 million to $76.8 million , or 13.6% for the six months ended June 30, 2013 compared to $67.7 million for the six months ended June 30, 2012 . Net income attributable to IPG Photonics Corporation as a percentage of our net sales decreased by 1.0 percentage point to 24.8% for the six months ended June 30, 2013 from 25.8% for the six months ended June 30, 2012 due to the factors described above.

Liquidity and Capital Resources

Our principal sources of liquidity as of June 30, 2013 consisted of cash and cash equivalents of $369.5 million, unused credit lines and overdraft facilities of $61.6 million and working capital (excluding cash and cash equivalents) of $226.9 million. This compares to cash and cash equivalents of $384.1 million, unused credit lines and overdraft facilities of $61.4 million and working capital (excluding cash and cash equivalents) of $155.5 million as of December 31, 2012 . The decrease in cash and cash equivalents of $14.6 million from December 31, 2012 relates primarily to cash provided by operating activities in the six months ended June 30, 2013 of $24.3 million which includes cash payments for corporation tax in Germany of approximately $32 million for a final payment of fiscal year 2011 and revised estimated payment for fiscal year 2012 which both became due when we filed our fiscal year 2011 German tax return. Also, cash provided by financing activities of $1.7 million was offset by cash used in investing activities of $39.2 million which mostly relate to investments in fixed assets and our acquisition during the first quarter.

Our long-term debt consists primarily of a $13.3 million secured variable-rate note, of which $1.3 million is the current portion. This debt matures in June 2015, at which time the outstanding debt balance would be $10.7 million. The variable interest rate was fixed by means of interest rate swap instruments.

We believe that our existing cash and marketable securities, our cash flows from operations and our existing lines of credit provides us with the financial flexibility to meet our liquidity and capital needs, as well as to complete acquisitions of complementary businesses and technologies. Our future long-term capital requirements will depend on many factors including our level of sales, the impact of economic environment on our sales levels, the timing and extent of spending to support development efforts, the expansion of the global sales and marketing activities, the timing and introductions of new products, the need to ensure access to adequate manufacturing capacity and the continuing market acceptance of our products. The following table details our line-of-credit facilities as of June 30, 2013 :

Table of Contents




Description	Available Principal	Interest Rate	Maturity	Security
U.S. Revolving Line of Credit (1)	Up to $35.0 million	LIBOR plus 1.125% to 1.625%, depending on our performance	June 2015	Unsecured
Euro Credit Facility (Germany)(2)	Euro 20.0 million ($26.0 million)	Euribor + 1.25% or EONIA 1.75%	June 2014	Unsecured, guaranteed by parent company
Euro Overdraft Facilities	Euro 1.9 million ($2.5 million)	1.3%-6.5%	October 2013	Common pool of assets of German and Italian subsidiaries


(1)	$14.1 million of this revolving credit facility is available to our foreign subsidiaries in their respective local currencies, including India, China, Japan and South Korea. There were no drawings at June 30, 2013 .


(2)	$16.9 million of this credit facility is available to our German subsidiary, $3.9 million is available to our Russian subsidiary and $5.2 million is available to our Italian subsidiary. Total drawings at June 30, 2013 was $1.8 million with an interest rate of 1.3% .

Our largest committed credit lines are with Bank of America and Deutsche Bank in the amounts of $35.0 million and $26.0 million , respectively, and neither of them is syndicated.

We are required to meet certain financial covenants associated with our U.S. revolving line of credit and long-term debt facilities. These covenants, tested quarterly, include a debt service coverage ratio and a funded debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”) ratio. The debt service coverage covenant requires that we maintain a trailing twelve month ratio of cash flow to debt service that is greater than 1.5:1. Debt service is defined as required principal and interest payments during the period. Cash flow is defined as EBITDA less unfunded capital expenditures. The funded debt to EBITDA covenant requires that the sum of all indebtedness for borrowed money on a consolidated basis shall be less than two times our trailing twelve months EBITDA. We were in compliance with all such financial covenants as of and for the three months ended June 30, 2013 .

The financial covenants in our loan documents may cause us to not take 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 by $54.2 million to $24.3 million for the six months ended June 30, 2013 from $78.5 million for the six months ended June 30, 2012 , primarily resulting from:


•	A decrease in income and other taxes payable of $32.4 million in the six months ended June 30, 2013 compared to an increase of $11.0 million in the six months ended June 30, 2012 ;


•	An increase in inventory of $23.8 million in the six months ended June 30, 2013 compared to an increase of $10.1 million in the six months ended June 30, 2012 ;


•	An increase in accounts receivable of $21.2 million in the six months ended June 30, 2013 compared to an increase of $13.3 million in the six months ended June 30, 2012 ; offset by


•	An increase in cash provided by net income after adding back non-cash charges of $103.9 million in the six months ended June 30, 2013 as compared to $95.0 million in the same period in 2012 .

Given our vertical integration, rigorous and time-consuming testing procedures for both internally manufactured and externally purchased components and the lead time required to manufacture components used in our finished products, the rate at which we turn inventory has historically been comparatively low when compared to our cost of sales. Also, our historic growth rates required investment in inventories to support future sales and enable us to quote short delivery times to our customers, providing what we believe is a competitive advantage. Furthermore, if there was a disruption to the manufacturing capacity of any of our key technologies, our inventories of components should enable us to continue to build finished products for a reasonable period of time. We believe that we will continue to maintain a relatively high level of inventory compared to our cost of sales. As a result, we expect to have a significant amount of working capital invested in inventory. A reduction in our level of net sales or the rate of growth of our net sales from their current levels would mean that the rate at which we are able to convert our inventory into cash would decrease.

Investing activities. Net cash used in investing activities was $39.2 million and $20.3 million in the six months ended June 30, 2013 and 2012 , respectively. The cash used in investing activities in 2013 related to the construction of new buildings in the US, Germany and Russia as well as purchases of machinery and equipment and our acquisition during the first quarter. The cash used in investing activities in 2012 related to the construction of new buildings in the U.S., Germany and Russia. These expenditures were partially offset by the proceeds from the maturity of short-term investments of $15.7 million .

We expect to incur between $75 million and $80 million in capital expenditures, excluding acquisitions in 2013. The timing and extent of any capital expenditures in and between periods can have a significant effect on our cash flow. Many of the capital expenditure projects that we undertake have long lead times and are difficult to cancel or defer to a later period.

Financing activities. Net cash provided by financing activities was $1.7 million and $111.0 million in the six months ended June 30, 2013 and 2012 , respectively. The cash provided by financing activities in 2013 was primarily related to the cash provided by the exercise of stock options, issuances under our employee stock purchase plan and the related tax benefits of the exercises partially offset by the payments on our long-term debt and line-of-credit facilities. The cash provided by financing activities in 2012 was primarily related to the follow-on public stock offering for which we received $168.0 million , net of offering expenses partially offset by the repurchased 22.5% redeemable noncontrolling interest in our Russian subsidiary of $55.4 million.

This Quarterly Report on Form 10-Q contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, and we intend that such forward-looking statements be subject to the safe harbors created thereby. For this purpose, any statements contained in this Quarterly Report on Form 10-Q except for historical information are forward-looking statements. Without limiting the generality of the foregoing, words such as “may,” “will,” “expect,” “believe,” “anticipate,” “intend,” “could,” “estimate,” or “continue” or the negative or other variations thereof or comparable terminology are intended to identify forward-looking statements. In addition, any statements that refer to projections of our future financial performance, trends in our businesses, or other characterizations of future events or circumstances are forward-looking statements.

The forward-looking statements included herein are based on current expectations of our management based on available information and involve a number of risks and uncertainties, all of which are difficult or impossible to accurately predict and many of which are beyond our control. As such, our actual results may differ significantly from those expressed in any forward-looking statements. Factors that may cause or contribute to such differences include, but are not limited to, those discussed in more detail in Item 1, “Business” and Item 1A, “Risk Factors” of Part I of our Annual Report on Form 10-K for the year ended December 31, 2012 . Readers should carefully review these risks, as well as the additional risks described in other documents we file from time to time with the Securities and Exchange Commission. In light of the significant risks and uncertainties inherent in the forward-looking information included herein, the inclusion of such information should not be regarded as a representation by us or any other person that such results will be achieved, and readers are cautioned not to rely on such forward-looking information.

Recent Accounting Pronouncements

Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require

adoption until a future date are not expected to have a material impact on our financial statements upon adoption.

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 . Our investments have limited exposure to market risk. To minimize this risk, we maintain a portfolio of cash, cash equivalents and short-term investments, consisting primarily of bank deposits, money market funds and short-term government securities. The interest rates are variable and fluctuate with current market conditions. 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 interest rate swap agreements. Although our U.S. revolving line of credit and our Euro credit facility have variable rates, we do

Table of Contents

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 Japanese Yen, the Russian Ruble, and Chinese Yuan. As a result, our international operations give rise to transactional market risk associated with exchange rate movements of the U.S. dollar, the Euro, the Japanese Yen, the Russian Ruble, and Chinese Yuan. Gain on foreign exchange transactions totaled $0.1 million for the three months ended June 30, 2013 . Gain on foreign exchange transactions totaled $3.4 million for the three months ended June 30, 2012 . Management attempts to hedge these exposures by partially or fully off-setting foreign currency denominated assets and liabilities at our subsidiaries that operate in different functional currencies. 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 hedges as of June 30, 2013 . 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 last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we are party to various legal proceedings and other disputes incidental to our business. There have been no material developments to those proceedings reported in our Annual Report on Form 10-K for the year ended December 31, 2012 , except that Company was named a defendant in an action by a former consultant filed in August 2013 in the United States District Court for the District of Massachusetts. The plaintiff alleges in his complaint that we misappropriated certain trade secrets from him relating to beam couplers and beam switches in connection with a consulting relationship, that we engaged in unfair trade practices and that he should be identified as an inventor on a patent owned by us. He seeks damages in an unspecified amount, double damages for misappropriation of trade secrets, treble damages for unfair trade practices and correction of inventorship on one patent. We have not answered the complaint. Although we intend to vigorously contest the claims against us, we cannot predict the outcome of the proceeding.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2012 , which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form 10-K and Quarterly Reports on Form 10-Q are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

We are subject to litigation alleging that we are infringing third-party intellectual property rights. Intellectual property claims could result in costly litigation and harm our business.

In recent years, there has been significant litigation involving intellectual property rights in many technology-based industries, including our own. We face risks and uncertainties in connection with such litigation, including the risk that patents issued to others may harm our ability to do business; that there could be existing patents of which we are unaware that could be pertinent to our business; and that it is not possible for us to know whether there are patent applications pending that our products might infringe upon, since patent applications often are not disclosed until a patent is issued or published. Moreover, the frequency with which new patents are granted and the diversity of jurisdictions in which they are granted make it impractical and expensive for us to monitor all patents that may be relevant to our business.

From time to time, we have been notified of allegations and claims that we may be infringing patents or intellectual property rights owned by third parties. We are presently defending a lawsuit brought by a former consultant alleging in his complaint that we misappropriated certain trade secrets from him relating to beam couplers and beam switches in connection with the consulting relationship, that we engaged in unfair trade practices and that he should be identified as an inventor on a patent owned by us. He seeks damages in an unspecified amount, double damages for misappropriation of trade secrets, treble damages for unfair trade practices and correction of inventorship on one patent.

In 2007, we settled two patent infringement lawsuits filed against us and in 2010 we settled another patent infringement lawsuit filed against us. Following a federal jury trial in 2011, we won a patent infringement lawsuit asserted by IMRA America, Inc. in 2006 alleging that certain products we produce infringe one U.S. patent allegedly owned by IMRA America. IMRA America has also informed us that it has patents and applications in the United States and in foreign jurisdictions directed to fiber lasers and fiber amplifiers, but has not asserted them against us. We are engaged in opposition proceedings in Japan and Germany with respect to two patents allegedly owned by IMRA America related to the patent IMRA America asserted against us in the United States. In Japan, the patent office invalidated two claims, and subsequently the Japanese IP High Court concluded that the remaining 49 claims of an IMRA America patent were invalid. IMRA is appealing the IP High Court decision. The German Patent and Trademark Office concluded that IMRA's claims corresponding to its original patent request and several auxiliary requests were not patentable and found that claims relating to IMRA's final auxiliary request were patentable. We are appealing a portion of this decision favorable to IMRA.

There can be no assurance that we will be able to dispose without a material effect any claims or other allegations made or asserted in the future. The outcome of any litigation is uncertain. Even if we ultimately are successful on the merits of any such litigation or re-examination, legal and administrative proceedings related to intellectual property are typically expensive and time-consuming, generate negative publicity and divert financial and managerial resources. Some litigants may have greater financial resources than we have and may be able to sustain the costs of complex intellectual property litigation more easily than we can.

Table of Contents

If we do not prevail in any intellectual property litigation brought against us, it could affect our ability to sell our products and materially harm our business, financial condition and results of operations. These developments could adversely affect our ability to compete for customers and increase our revenues. Plaintiffs in intellectual property cases often seek, and sometimes obtain, injunctive relief. Intellectual property litigation commenced against us could force us to take actions that could be harmful to our business, competitive position, results of operations and financial condition, including the following:


•	stop selling our products or using the technology that contains the allegedly infringing intellectual property;


•	pay actual monetary damages, royalties, lost profits or increased damages and the plaintiff's attorneys' fees, which individually or in the aggregate may be substantial; and


•	attempt to obtain a license to use the relevant intellectual property, which may not be available on reasonable terms or at all.

In addition, intellectual property lawsuits can be brought by third parties against OEMs and end users that incorporate our products into their systems or processes. In some cases, we indemnify OEMs against third-party infringement claims relating to our products and we often make representations affirming, among other things, that our products do not infringe the intellectual property rights of others. As a result, we may incur liabilities in connection with lawsuits against our customers. Any such lawsuits, whether or not they have merit, could be time consuming to defend, damage our reputation or result in substantial and unanticipated costs.
