NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1.	BASIS OF PRESENTATION

Advanced Energy Industries, Inc., a Delaware corporation, and its wholly-owned subsidiaries ("we," "us," "our," "Advanced Energy," or the "Company") design, manufacture, sell, and support power conversion products that transform power into various usable forms. Our products enable manufacturing processes that use thin film deposition for various products, such as semiconductor devices, flat panel displays, thin film renewables, and architectural glass. We also supply thermal instrumentation products for advanced temperature control in the thin film process for these same markets. Our solar inverter products support renewable power generation solutions for primarily commercial, and utility-scale solar projects and installations. Our network of global service support centers provides a recurring revenue opportunity as we offer repair services, conversions, upgrades, and refurbishments to companies using our products. We also offer a wide variety of operations and maintenance service plans that can be tailored for individual photovoltaic ("PV") sites of all sizes.

We are organized into two strategic business units ("SBU") based on the products and services provided.

Thin Films Processing Power Conversion and Thermal Instrumentation ("Thin Films") SBU offers products for direct current ("DC"), pulsed DC mid frequency, and radio frequency ("RF") power supplies, matching networks and RF instrumentation as well as thermal instrumentation products.

Solar Energy SBU offers both a transformer-based or transformerless advanced grid-tied PV inverter solution for commercial and utility-scale system installations. Our PV inverters are designed to convert renewable solar power, drawn from large and small scale solar arrays, into high-quality, reliable electrical power.

In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting of normal, recurring adjustments, necessary to present fairly the financial position of the Company at June 30, 2013 , and the results of our operations and cash flows for the three and six months ended June 30, 2013 and 2012 .

The Condensed Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012 and other financial information filed with the SEC.

ESTIMATES AND ASSUMPTIONS

The preparation of our Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires us to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We believe that the significant estimates, assumptions, and judgments when accounting for items and matters such as allowances for doubtful accounts, excess and obsolete inventory, warranty reserves, acquisitions, asset valuations, goodwill, asset life, depreciation, amortization, recoverability of assets, impairments, deferred revenue, stock option and restricted stock grants, taxes, and other provisions are reasonable, based upon information available at the time they are made. Actual results may differ from these estimates, making it possible that a change in these estimates could occur in the near term.

REVENUE RECOGNITION

Our accounting policies are described in our audited Consolidated Financial Statements and Notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2012 .

NEW ACCOUNTING STANDARDS

From time to time, the Financial Accounting Standards Board ("FASB") or other standards setting bodies issue new accounting pronouncements. Updates to the FASB Accounting Standards Codification ("ASC") are communicated through issuance of an Accounting Standards Update ("ASU"). Unless otherwise discussed, we believe that the impact of recently issued guidance,

whether adopted or to be adopted in the future, is not expected to have a material impact on the Condensed Consolidated Financial Statements upon adoption.


NOTE 2.	BUSINESS ACQUISITION & DISPOSITION

Acquisition

Solvix SA

On November 8, 2012, we acquired Solvix SA ("Solvix"), a privately-held Switzerland based company, pursuant to a stock purchase agreement dated November 8, 2012 between AEI International Holdings, CV ("AEI CV"), a wholly-owned subsidiary of Advanced Energy incorporated in the Netherlands, and CPA Group SA ("CPA Group"), a privately held Switzerland company. Pursuant to the stock purchase agreement, AEI CV purchased 100% of the outstanding stock of Solvix.

We acquired all of the outstanding Solvix common stock for total consideration with a fair value of approximately $21.2 million consisting of cash payments totaling $16.0 million , net of cash acquired, and contingent consideration payable to the former shareholders of Solvix. The additional cash consideration of up to $7.9 million is payable to CPA Group if certain milestone targets are met during the year ending December 31, 2013 and certain financial targets are met in the three years ended December 31, 2015. The estimated fair value of this contingent consideration is approximately $5.3 million as of November 8, 2012, of which the remaining balance of $2.0 million is included in Other accrued expenses and $2.3 million is included in Other long-term liabilities on the Condensed Consolidated Balance Sheet.

Solvix is a manufacturer of power supplies for the surface treatment and thin films industry. Solvix manufactures products that bring plasma-based sputtering and cathodic arc deposition applications to Advanced Energy's existing product portfolio and is included in our Thin Film business unit. Solvix has approximately 10 employees and had revenues of $5.2 million in its fiscal year ended September 30, 2012.

The Solvix product line will continue to be manufactured in Switzerland under a contract manufacturing agreement with CPA Group until production is moved to our Shenzhen facility in 2013.

The components of the fair value of the total consideration transferred for the Solvix acquisition are as follows (in thousands):



Cash paid to owners	$	16,673

The cost of the acquisition may increase or decrease based on the final amount payable to the former owner of Solvix related to the financial targets to be met during the three years ending December 31, 2015. Advanced Energy is in the process of finalizing valuations of other intangibles, estimates of the fair value of liabilities associated with the acquisition and deferred taxes and expects to complete the acquisition accounting and required disclosures prior to December 31, 2013.

Refusol Holding

On April 8, 2013, we acquired all the outstanding shares of Refusol Holding GmbH pursuant to a Sale and Purchase Agreement (the "Agreement ") between AEI Holdings, GmbH (formerly Blitz S13-103, GmbH) ("AEI Holdings"), an indirect wholly-owned subsidiary of Advanced Energy Industries, Inc. and Jolaos Verwaltungs GmbH ("Jolaos") and Prettl Beteilgungs Holding GmbH. Refusol Holding GmbH ("Refusol Holding") owns all of the shares of Refusol GmbH and its subsidiaries (collectively and together with Refusol Holding, "Refusol"). Refusol develops, manufactures, distributes and services photovoltaic inverters.

All of the outstanding shares of Refusol Holding were acquired for total consideration of approximately $89.1 million , consisting of a cash payment of $77.2 million , net of cash acquired and a working capital reduction and assumption of debt totaling $11.9 million . The agreement calls for additional cash consideration if certain stretch financial targets are met by our Solar Energy

Goodwill and intangible assets are recorded in the functional currency of the entity and are subject to changes due to translation at each balance sheet date. The goodwill associated with the acquisition is the result of expected synergies and expansion of the technology into additional markets that we already serve.

The cost of the acquisition may increase or decrease based on the final amount payable to the former owner of Refusol related to the financial targets to be met during the twelve month period subsequent to April 1, 2013. Advanced Energy is in the process of finalizing valuations of other intangibles, property, plant and equipment, estimates of the fair value of liabilities associated with the acquisition and deferred taxes.

The results of Refusol operations are included in our Condensed Consolidated Statements of Operations beginning April 8, 2013 . For the period ended June 30, 2013 , net sales of approximately $19.8 million and operating loss of $5.4 million attributable to Refusol were included in the consolidated results of operations. Refusol's results of operations included restructuring charges of $3.8 million and amortization of purchased intangible assets of $0.7 million .

Disposition

On October 15, 2010, we completed the sale of our gas flow control business, which included the Aera ^® mass flow control and related product lines to Hitachi Metals, Ltd. ("Hitachi"), for approximately $43.3 million . Assets and liabilities sold included, without limitation, inventories, real property in Hachioji, Japan, equipment, certain contracts, intellectual property rights related to the gas flow control business and certain warranty liability obligations.

In connection with the closing of this asset disposition, we entered into a Master Services Agreement and a Supplemental Transition Services Agreement pursuant to which we provided certain transition services until October 2011 and we became an authorized service provider for Hitachi in all countries other than Japan. In March 2012, we entered into an agreement to sell certain fixed assets to Hitachi and cease providing contract manufacturing services. As of May 31, 2012, we ceased providing contract manufacturing services to Hitachi and completed the sale of certain fixed assets related to that manufacturing. The sale of these assets resulted in a $1.9 million gain, which is recorded in Other income (expense), net in our Condensed Consolidated Statements of Operations. As of June 30, 2012 , all manufacturing activities and relationships with Hitachi related to the previously owned gas flow control business have ended. We do not anticipate any additional activity with Hitachi in respect of these assets that would materially impact our financial statements in the future.

In accordance with authoritative accounting guidance for reporting discontinued operations, for the periods reported in this Form 10-Q, the results of continuing operations were reduced by the revenue and costs associated with the gas flow control business, which are included in the Income from discontinued operations, net of income taxes, in our Condensed Consolidated Statements of Operations.

Operating results of discontinued operations are as follows (in thousands):

Effective tax rate	17.8		%	32.8		%	32.6		%	32.3		%

The provision for income taxes is based on the current estimate of the annual effective tax rate adjusted to reflect the impact of discrete items. The tax expense for both the three and six months ended June 30, 2013 , reflects a benefit primarily attributable to restructuring expenses.

Our policy is to classify accrued interest and penalties related to unrecognized tax benefits in our income tax provision. For the three and six months ended June 30, 2013 and 2012 , the amount of interest and penalties accrued related to our unrecognized tax benefits was not significant.


NOTE 4.	EARNINGS PER SHARE FOR CONTINUING OPERATIONS

Basic earnings per share ("EPS") is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the numerator is increased to exclude charges that would not have been incurred, and the denominator is increased to include the number of additional common shares that would have been outstanding (using the if-converted and treasury stock methods), if securities containing potentially dilutive common shares (e.g., stock options and restricted stock units) had been converted to common shares, and if such assumed conversion is dilutive.

As of June 30, 2013 , we do not believe any of the underlying issuers of our marketable securities are presently at risk of default.


NOTE 6.	DERIVATIVE FINANCIAL INSTRUMENTS

We are impacted by changes in foreign currency exchange rates. We manage these risks through the use of derivative financial instruments, primarily forward contracts. During the three and six months ended June 30, 2013 and 2012 , we entered into foreign currency exchange forward contracts to manage the exchange rate risk associated with intercompany debt denominated in nonfunctional currencies. These derivative instruments are not designated as hedges; however, they do offset the fluctuations of our intercompany debt due to foreign exchange rate changes. These forward contracts are typically for one month periods. At June 30, 2013 and December 31, 2012 we had outstanding Euro, Swiss Franc, and Canadian Dollar forward contracts.

The notional amount of foreign currency exchange contracts at June 30, 2013 and 2012 was $39.0 million and $31.2 million , respectively, and the fair value of these contracts was not significant at June 30, 2013 and 2012 . During the three months ended June 30, 2013 and 2012 , we recognized an insignificant gain and a $1.5 million gain, respectively, on our foreign currency exchange contracts. During the six months ended June 30, 2013 and 2012, we recognized a gain of $0.6 million and $0.5 million , respectively. These gains and losses were offset by corresponding gains and losses on the related intercompany debt and both are included as a component of Other income (expense), net, in our Condensed Consolidated Statements of Operations.

NOTE 13.	RESTRUCTURING COSTS

In April 2013, we committed to a restructuring plan to take advantage of additional cost saving opportunities in connection with our acquisition of Refusol. Under the plan, we will consolidate certain facilities, further centralize our manufacturing and rationalize certain products to most effectively meet customer needs. Collectively, these steps will enable us to more efficiently use our resources to achieve strategic goals.

As a part of the product rationalization initiated under the restructuring plan, we determined that the intangible assets associated with certain technology should be tested for recoverability. To test the intangible assets for recoverability, we compared the carrying value of the assets with their fair value which resulted in an impairment of $17.7 million which is recorded in restructuring charges (benefit) and asset impairment in the Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2013 .

Over the next six months, we will continue to consolidate facilities; transfer the remaining supply chain activities of our Thin Films business unit to the Shenzhen, China manufacturing facility; and rationalize the inverter product line to most effectively meet the needs of its customers. As a result, we anticipate additional charges in the amount of $11.0 million to $13.0 million , of which approximately $1.5 million to $3.0 million are expected to be cash expenditures. Estimated total expenses to be incurred under the plan are approximately $35.0 million to $37.0 million . Of the this total, approximately $5.5 million to $6.0 million relates to severance costs, $4.5 million to $5.0 million is for space consolidation, and $25.0 million to $26.0 million will be for product rationalization and impairments of the intangible assets associated with the technology around those products.

The following table summarizes the components of our restructuring costs incurred under the 2013 plan (in thousands):



	Three and Six Months Ended

In September 2011, we approved and committed to several initiatives to realign our manufacturing and research and development activities in order to foster growth and enhance profitability. These initiatives are designed to align research and development activities with the location of our customers and reduce production costs. Under this plan, we reduced our global headcount, consolidated our facilities by terminating or exiting several leases, and recorded impairments for assets no longer in use due to the restructuring of our business. All activities under this restructuring plan were completed prior to December 31, 2012. The following table summarizes our restructuring liabilities under this plan (in thousands):

Stock Options

Stock option awards, other than awards under our 2012-2014 Long Term Incentive Plan ("LTI Plan"), are generally granted with an exercise price equal to the market price of our common stock at the date of grant, a four -year vesting schedule, and a term of 10 years.

Under the LTI Plan, we made grants of performance based options and awards during the first quarter of 2012, which will vest annually over a three-year period based on the Company's achievement of return on net assets targets established by our Board of Directors at the beginning of each year. These awards are granted with an exercise price equal to the market price of our common stock at the date of grant and have a term of 10 years. The fair value of each grant was estimated on the date of grant using the Black-Scholes-Merton option pricing model utilizing an expected volatility of 61.5% , a risk-free rate of 1.2% , a dividend yield of zero , and an expected term of 5.6 years. The weighted-average grant date fair value of the options is $6.19 per share. The weighted average grant date fair value of the awards is $11.03 per share.

NOTE 20.	CREDIT FACILITIES

In October 2012, we, along with two of our wholly-owned subsidiaries, AE Solar Energy, Inc. and Sekidenko, Inc., entered into a Credit Agreement, subsequently amended in November 2012 and August 2013, (the "Credit Agreement") with Wells Fargo Bank, National Association ("Wells Fargo"), as agent for and on behalf of certain lenders (each a "Lender"), which provides for a new secured revolving credit facility of up to $50.0 million (the "Credit Facility"). The Credit Facility provides us with the ability to borrow up to $50.0 million , although the amount of the Credit Facility may be increased by an additional $25.0 million up to a total of $75.0 million subject to receipt of lender commitments and other conditions. Borrowings under the Credit Facility are subject to a borrowing base based upon our domestic accounts receivable and inventory and are available for various corporate purposes, including general working capital, capital expenditures, and certain permitted acquisitions. The Credit Agreement also permits us to issue letters of credit. The maturity date of the Credit Facility is October 12, 2017 .

At our election, the loans comprising each borrowing will bear interest at a rate per annum equal to either: (a) a "base rate" plus between one-half ( 0.5% ) and one ( 1.0% ) full percentage point depending on the amount available for additional draws under the Credit Facility ("Base Rate Loan"); or (b) the LIBOR rate then in effect plus between one and one-half ( 1.5% ) and two ( 2% ) percentage points depending on the amount available for additional draws under the Credit Facility. The "base rate" for any Base Rate Loan will be the greatest of the federal funds rate plus one-half ( 0.5% ) percentage point; the one-month LIBOR rate plus one ( 1.0% ) percentage point; and Wells Fargo's "prime rate" then in effect. As of June 30, 2013 , the rate in effect was 4.25% .

The Credit Agreement requires us to pay certain fees to the Lenders and contains affirmative and negative covenants, which, among other things, require us to deliver to the Lenders specified quarterly and annual financial information, and limit us and our Guarantors (as defined below), subject to various exceptions and thresholds, from, among other things: (i) creating liens on our assets; (ii) merging with other companies or engaging in other extraordinary corporate transactions; (iii) selling certain assets or properties; (iv) entering into transactions with affiliates; (v) making certain types of investments; (vi) changing the nature of our business; and (vii) paying certain distributions or certain other payments to affiliates. Additionally, there are the following financial covenants: (i) during any period in which $12.5 million or less is available to us under the Credit Facility and for sixty (60) days thereafter, the Credit Agreement requires the maintenance of a defined consolidated fixed charge coverage ratio; and (ii) if there is any indebtedness under any issued and outstanding convertible notes, we are required to maintain a speficied level of liquidity.

The Credit Agreement requires us to pay certain fees to the Lenders, including a $2,500 collateral management fee for each month that the Credit Facility is in place, and a fee based on the unused amount of the Credit Facility. In addition, if the Credit Agreement is terminated by us within one (1) year we will be obligated to pay an early termination fee equal to one percent ( 1% ) of the maximum amount that may be drawn or borrowed under the Credit Facility. During the six months ended June 30, 2013 , we expensed $0.2 million in interest and fees related to unused line of credit fees and amortization of debt issuance costs. We did not borrow against the Credit Facility in the three and six month periods of 2013 .

Table Of Contents

Pursuant to a Guaranty and Security Agreement (the "GS Agreement"), borrowings under the Credit Facility are guaranteed by our wholly-owned subsidiaries Aera Corporation and AEI US Subsidiary, Inc., (collectively the " Guarantors"). Under the GS Agreement, we and the Guarantors granted the Lenders a security interest in certain, but not all, of our and the Guarantors' assets.

As part of the acquisition of Refusol described in Note 2. Business Acquisitions and Disposition , we assumed the outstanding debt of Refusol as of the acquisition date. There are three outstanding loans with banks related to this debt.

Refusol, GmbH has an outstanding loan agreement with Commerzbank Aktiengesellschaft ("Commerzbank") for up to 8.0 million Euros ("Commerzbank Loan Agreement"). The agreement allows Refusol to borrow up to 8.0 million Euros through various types of instruments including an overdraft (revolving) facilities, money market (term) loans, surety loans, or guarantees. There is no maturity date. Borrowings under the revolving credit facility bear interest at 5.32% . Surety and guarantee loans bear interest at 1.5% . Money market loans are granted by separate agreement when requested and must meet certain Euro thresholds related to the value depending on the maturity date chosen. The Commerzbank Loan Agreement requires the payment of a credit commission of 0.5% of the total loan amount. The agreement contains a various covenants including a financial covenant requiring a specified level of equity.

Refusol, GmbH also has an outstanding loan agreement with Bayerische Landesbank ("Bayern") allowing it to borrow up to 4.0 million Euros either as overdraft facilities, term loans, or guarantees with repayment occurring one lump sum at the maturity date of the individual transaction with respect to term loans, or maturity of the loan agreement which is July 31, 2013 (the "Bayern Loan Agreement"). The overdraft facility bears interest at 4.5% . Term loans bear interest at the money market rate established by Bayern at the time of the loan plus a margin of 1.9% . Guarantees bear interest at 1.25% and have an issuing fee per guarantee. Loan commitment fees are 0.25% on the unused portion of the total loan amount. The Bayern Loan Agreement contains certain reporting requirements and a financial covenant requiring a specified level of equity. We intend to enter into an extension of this loan agreement.

Refusol, Inc., a wholly-owned subsidiary of Refusol, GmbH located in the United States, has a revolving line of credit with Wells Fargo with an aggregate principal amount of $1.5 million and a maturity date of July 1, 2013 . Borrowings under the line of credit are secured by all of Refusol, Inc.'s accounts receivable, inventory, and property, plant, and equipment and a letter of credit issued under the Commerzbank Loan Agreement. The line of credit bears interest at either (a) a fluctuating rate per annum one quarter of one percent ( 0.25% ) above the Prime Rate or (b) the LIBOR rate then in effect plus two percent ( 2.0% ). Refusol, Inc. has the option to select the method of interest each month. A commitment fee of 0.125% is payable by Refusol, Inc. on the unused portion of the line of credit.

Total Sales

Overall, our sales increased $24.1 million , or 20.8% , to $139.7 million for the three months ended June 30, 2013 from $115.7 million for the three months ended June 30, 2012 . The increase in sales is the result of improved market conditions in our Thin Films business coupled with the acquisition of the three-phase string inverter product line. Sales in the thin film semiconductor markets continue to improve as we gained market share from prior design wins and expanded into other applications. The increase in sales in non-semiconductor markets is partially due to the acquisition of Solvix in the fourth quarter of 2012 coupled with increased sales to the flat panel display market.

For the six months ended June 30, 2013 , sales increased $30.1 million , or 13.6% , to $251.5 million from $221.4 million for the six months ended June 30, 2012 . The acquisition of the three-phase string inverter product line drove higher sales in our Solar Energy business while significant improvements in the flat panel display market resulted in higher sales in the Thin Films business unit.

Thin Films

Results for our Thin Films SBU for the three and six months ended June 30, 2013 and 2012 were as follows (in thousands):



	Three Months Ended June 30,				Six Months Ended June 30,
	2013		2012		2013		2012

Sales	$	71,702	$	64,843	$	133,479	$	125,233
Operating Income	14,406		8,881		21,917		12,048

Thin Films sales increased 10.6% to $71.7 million , or 51.3% of sales, for the three months ended June 30, 2013 versus $64.8 million , or 56.1% of sales, for the three months ended June 30, 2012 . For the six months ended June 30, 2013 sales were $133.5 million , an increase of $8.2 million , or 6.6% , from the same period of 2012. The increase for both periods reflects the market improvements noted above coupled with sales attributable to our acquisition of Solvix.

Table Of Contents

In the three months ended June 30, 2013 , sales in the thin film semiconductor market increased 12.1% to $41.1 million , or 29.4% of sales, from $36.6 million , or 31.7% of sales for the three months ended June 30, 2012 . For the six months ended June 30, 2013 , sales in the thin film semiconductor market were relatively flat at $73.8 million , or 29.3% of sales, compared to $75.0 million , or 33.9% of sales for the six months ended June 30, 2012 . The decline in end user capital expansion that characterized most of 2012 began to improve in the first quarter of 2013 and continued to increase through the second quarter of 2013. This coupled with prior design wins and expansion into etch and gas abatement applications drove higher sales in the semiconductor markets. Although the stronger capital spending is expected to remain through the remainder of the year and into 2014, we expect an industry pause which will result in sales being flat to slightly lower in the second half of 2013.

Sales in the thin film non-semiconductor capital equipment markets increased 20.9% to $18.5 million , or 13.2% of sales, for the three months ended June 30, 2013 compared to $15.3 million , or 13.2% of sales, for the three months ended June 30, 2012 . Sales in the thin film non-semiconductor capital equipment markets increased 38.4% to $35.1 million , or 14.0% of sales, for the six months ended June 30, 2013 compared to $25.4 million , or 11.5% of sales, for the six months ended June 30, 2012 . The markets that comprise the thin film non-semiconductor capital equipment markets include solar panel, flat panel display, data storage, architectural glass and other industrial thin film manufacturing equipment markets. Our customers in these markets are primarily global OEMs. The flat panel display market continues to drive the increase in the non-semiconductor market.

Sales to customers in the thin film solar panel market were relatively flat at $1.9 million , or 1.4% of total sales, for the three months ended June 30, 2013 as compared to $1.9 million , or 1.7% of total sales, for the three months ended June 30, 2012 . Sales to customers in the thin film solar panel market declined $1.7 million to $2.2 million for the six months ended June 30, 2013 as compared to the same period of 2012. As capacity in the solar panel market continues to exceed demand, significant new investment in this market is not anticipated in the foreseeable future. We expect sales to the solar panel market to remain at historically low levels through the second half of 2013.

The flat panel market experienced significant growth in the first quarter of 2013 which continued into the second quarter, increasing 277.3% for the three months ended June 30, 2013 and 379.9% in the six months ended June 30, 2013 compared to the same periods in 2012. Continued investments in the transition to active-matrix light-emitting diode ("AMOLED") technology have resulted in stronger sales through the first half of 2013. As installations of the investments from the first half of 2013 continue into the third quarter, we expect investments in the flat panel display market to pause resulting in lower demand for our products in the second half of 2013.

Our global support revenue decreased to $12.1 million , or 8.7% of total sales, for the three months ended June 30, 2013 , compared to $12.9 million , representing 11.2% of sales, for the three months ended June 30, 2012 . Global support revenue for the six months ended June 30, 2013 were flat compared to the six months ended June 30, 2012 . Although revenue declined slightly in the second quarter of 2013, growing interest in upgrades and refurbishment programs coupled with our preventative maintenance offering is expected to result in stable to higher revenues for our global support business.

Operating income for Thin Films was $14.4 million for the three months ended June 30, 2013 , an increase of $5.5 million from the same period of 2012. For the six months ended June 30, 2013 , operating income for Thin Films was $21.9 million compared to $12.0 million for the same period of 2012. The increase for both periods is the result of higher sales and improved gross margins resulting from improved manufacturing efficiencies on higher production volumes.

Solar Energy

Results for our Solar Energy SBU for the three and six months ended June 30, 2013 and 2012 are as follows (in thousands):



	Three Months Ended June 30,					Six Months Ended June 30,
	2013			2012		2013			2012

Sales	$	68,009		$	50,815	$	118,046		$	96,212
Operating income	(1,772		)	2,740		(1,564		)	3,233

Solar Energy sales were $68.0 million , or 48.7% of sales, for the three months ended June 30, 2013 as compared to $50.8 million , or 43.9% of sales, for the three months ended June 30, 2012 . For the six months ended June 30, 2013 , Solar Energy sales were $118.0 million , or 46.9% of sales, as compared to $96.2 million , or 43.4% of sales, for the three months ended June 30, 2012 . The increase in sales in 2013 for both the quarter and full year as compared to the same periods a year ago is due to the acquisition of the three-phase string inverter product line discussed in

Note 2. Business Acquisition and Disposition in Part I Item I of this Form 10-Q.

Table Of Contents

Operating income for Solar Energy was $(1.8) million for the three months ended June 30, 2013 as compared to $2.7 million for the three months ended June 30, 2012 . For the six months ended June 30, 2013, operating income was $(1.6) million compared to $3.2 million for the same period of 2012. The decrease in operating income for both the three months and six months ended June 30, 2013 as compared to the same periods in 2012 is due to additional operating expenses associated with the acquired three-phase string inverter product line. The benefits from the restructuring plan discussed below will begin impacting results in the third quarter of 2013 bringing these operating expenses down.

Backlog

Our overall backlog was $87.8 million at June 30, 2013 as compared to $92.7 million at December 31, 2012 . During the last week of the second quarter we received a large order in our solar business which we were not able to confirm through our normal process until the first day of the third quarter. Had this order been confirmed prior to June 30, 2013, our backlog would have been $123.7 million .

GROSS PROFIT

Our gross profit was $53.3 million , or 38.1% of sales, for the three months ended June 30, 2013 , as compared to $43.7 million , or 37.8% of sales for the three months ended June 30, 2012 . Gross profit for the six months ended June 30, 2013 was $95.1 million , or 37.8% of sales as compared to $83.5 million , or 37.7% of sales for the six months ended June 30, 2012 . The year-over-year increase in terms of absolute dollars for both the quarter and year-to-date periods is due to the overall increase in sales in our Thin Films business and the acquisition of the three-phase string inverter product line. Gross profit as a percentage of sales was relatively flat compared to the same quarter in the prior year as the mix of sales between our two business units shifted a higher portion to the Solar Energy business which has lower gross margins.

OPERATING EXPENSE

The following table summarizes our operating expenses as a percentage of sales for the three and six months ended June 30, 2013 and 2012 (in thousands):



	Three Months Ended June 30,									Six Months Ended June 30,

As a result of declines in certain markets that we serve, we initiated a plan in September 2011 to re-align our manufacturing and research and development activities to be closer to our customers and reduce production costs. These initiatives included headcount reductions, facilities closures, and asset impairments and were completed in the fourth quarter of 2012.

In April 2013, in connection with our acquisition of Refusol Holdings GmbH ("Refusol") described in Note 2. Business Acquisitions and Disposition in Part I Item I of this Form 10-Q, we committed to a restructuring plan to take advantage of additional cost saving opportunities. During the three months ended June 30, 2013, we incurred restructuring charges of $24.2 million related to reductions in headcount, facility closures, and intangible asset impairments. Over the next six months, we will continue our efforts to consolidate facilities including moving the remaining manufacturing in Bend, Oregon to our Fort Collins, Colorado facility; transfer the remaining supply chain activities of our Thin Films business unit to the Shenzhen, China manufacturing facility; and rationalize the inverter product line. As a result, we anticipate additional charges in the amount of $11.0 million to $13.0 million , of which approximately $1.5 million to $3.0 million are expected to be cash expenditures. Estimated total expenses to be incurred under the plan are approximately $35.0 million to $37.0 million . Of this total, approximately $5.5 million to $6.0 million relates to severance costs, $4.5 million to $5.0 million is for space consolidation, and $25.0 million to $26.0 million will be for product rationalization and impairments of the intangible assets associated with the technology related to those products. The actions taken under this restructuring plan as well as those underway and already taken are expected to deliver annual savings of approximately $70.0 to $75.0 million.

Research and Development

The markets we serve constantly present opportunities to develop products for new or emerging applications and require technological changes driving for higher performance, lower cost, and other attributes that we expect may advance our customers’ products. We believe that continued and timely development of new and differentiated products, as well as enhancements to existing products to support customer requirements, are critical for us to compete in the markets we serve. Accordingly, we devote significant personnel and financial resources to the development of new products and the enhancement of existing products, and we expect these investments to continue. All of our research and development costs have been expensed as incurred, except those incurred as a result of a business acquisition.

Research and development expenses for the three months ended June 30, 2013 were $15.7 million , or 11.3% of sales, as compared to $14.5 million , or 12.5% of sales, for the three months ended June 30, 2012 . Research and development costs increased slightly in the three months ended June 30, 2013 as compared to the same period in 2012 primarily due to the acquisition of the three-phase string inverter product line and the addition of expenses incurred for the research and development activities related to that product. Research and development costs were flat for the six months ended June 30, 2013 as compared to the same period of 2012. The higher costs associated with the acquisition of the three-phase string inverter product were offset by the full year impact in 2013 of the cost savings associated with the restructuring plan announced in late 2011 and implemented throughout 2012.

Selling, General and Administrative

Our selling expenses support domestic and international sales and marketing activities that include personnel, trade shows, advertising, third-party sales representative commissions, and other selling and marketing activities. Our general and administrative expenses support our worldwide corporate, legal, tax, financial, governance, administrative, information systems, and human resource functions in addition to our general management, including acquisition-related activities.

Selling, general and administrative ("SG&A") expenses increased $6.2 million and $3.8 million in the three months and six months ended June 30, 2013 as compared to the same periods in 2012 . The increases are primarily due to the acquisition of the three-phase string inverter product line coupled with higher purchased services and incentive compensation accruals.

Amortization Expense

Amortization of intangible assets expense was $2.0 million and $4.2 million for the three months and six months ended June 30, 2013 , compared to $1.4 million and $2.7 million for the same periods ending June 30, 2012 . During the second quarter of 2013, we recorded a partial impairment of intangible assets acquired from PV Powered in May 2010. As a result of the acquisition of the three-phase string inverter product line, we assessed the overall Solar product line for product optimization, resulting in an impairment to the technology purchased from PV Powered. This reduced amortization related to these products which was offset by amortization related to the intangible assets acquired with Refusol and Solvix.

Other Income (Expenses), net

Other income (expenses), net consists primarily of interest income and expense, foreign exchange gains and losses, gains and losses on sales of fixed assets, and other miscellaneous items. Other income (expenses), net was a $0.3 million loss for the three months ended June 30, 2013 as compared to a $ 1.8 million gain in the same period of 2012 . For the six month period ended June 30, 2013, other income (expenses), net was a loss of $0.5 million compared to income of $2.2 million in the prior year. The loss in the current year is primarily due to foreign exchange losses while the prior year gain resulted from the sale of fixed assets for both the quarter and year-to-date periods.

Provision for Income Taxes

We recorded an income tax benefit from continuing operations for the three months ended June 30, 2013 of $2.1 million compared to expense of $4.3 million for the three months ended June 30, 2012 , resulting in effective tax rates of 17.8% and 32.8% , respectively. For the six months ended June 30, 2013, we recorded an income tax benefit of $1.4 million compared to an expense of $4.6 million for the same period of 2012, resulting in effective tax rates of 32.6% and 32.3% , respectively. Our tax rate is lower than the U.S. federal income tax rate primarily due to the benefit of earnings in foreign jurisdictions which are subject to lower tax rates. In addition, during the three months ended June 30, 2013 , we recognized a discrete tax benefit of $1.4 million related to the January 2, 2013 reinstatement of the 2012 U.S. research and development tax credit.

Table Of Contents

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

Discontinued Operations

On October 15, 2010, we completed the sale of our gas flow control business, which includes the Aera ^® mass flow control and related product lines to Hitachi, for $43.3 million . Assets and liabilities sold include, without limitation, inventory, real property in Hachioji, Japan, equipment, certain contracts, intellectual property rights related to the gas flow control business, and certain warranty liability obligations. Results of continuing operations for 2012 were reduced by the revenue and costs associated with the gas flow control business which are included in Income from discontinued operations, net of income taxes, in our Condensed Consolidated Statements of Operations.

Non-GAAP Results

To evaluate business performance against business objectives and for planning purposes, management uses non-GAAP results. We believe these measures will enhance investors’ ability to review our business from the same perspective as management and facilitate comparisons of this period’s results with prior periods. These non-GAAP measures are not in accordance with U.S. GAAP and may differ from non-GAAP methods of accounting and reporting used by other companies. The presentation of this additional information should not be considered a substitute for results prepared in accordance with U.S. GAAP.

The non-GAAP results presented below exclude the impact of restructuring charges, stock-based compensation, amortization of intangible assets, and acquisition-related costs (in thousands):

Impact of Inflation

In recent years, inflation has not had a significant impact on our operations. However, we continuously monitor operating price increases, particularly in connection with the supply of component parts used in our manufacturing process. To the extent permitted by competition, we pass increased costs on to our customers by increasing sales prices over time. From time to time, we may also receive pressure from customers to decrease sales prices due to reductions in the cost structure of our products from cost improvement initiatives and decreases in component part prices. Sales price increases and decreases, however, were not significant in any of the periods presented herein.

Liquidity and Capital Resources

LIQUIDITY

We believe that adequate liquidity and cash generation is important to the execution of our strategic initiatives. Our ability to fund our operations, acquisitions, capital expenditures, and product development efforts may depend on our ability to generate cash from operating activities which is subject to future operating performance, as well as general economic, financial, competitive,

Table Of Contents

legislative, regulatory, and other conditions, some of which may be beyond our control. Our primary sources of liquidity are our available cash, investments, and cash generated from current operations as well as our credit facilities discussed in Note 20. Credit Facilities in Part I Item 1 of this Form 10-Q.

At June 30, 2013 , we had $99.1 million in cash, cash equivalents, and marketable securities. We believe that our current cash levels and our cash flows from future operations will be adequate to meet anticipated working capital needs, anticipated levels of capital expenditures, and contractual obligations for the next twelve months. We may seek additional financing from time to time.

On October 12, 2012, we entered into an agreement with Wells Fargo Bank, National Association which provides for a secured revolving credit facility ("Credit Facility") of up to $50.0 million. Borrowings under the Credit Facility are subject to a borrowing base based upon our accounts receivable and inventory and are available for various corporate purposes. The Credit Facility provides us further flexibility for execution of our strategic plans including acquisitions. With the acquisition of Refusol, we assumed the outstanding balances under their existing lines of credit. Refusol has three notes with various banks that provide up to 12.0 million Euros of borrowing and $1.5 million of borrowing. As of June 30, 2013 there was $13.3 million outstanding on these notes. For more information on these Credit Facilities see

Note 20. Credit Facilities of our Consolidated Financial Statements.

On October 30, 2012, we announced a $25.0 million share repurchase program authorized by our Board of Directors. The repurchase program is authorized through October 2013, requires no minimum number of shares to be repurchased, and may be discontinued at any time. No repurchases have been made under this program.

2013 CASH FLOWS COMPARED TO 2012

Net cash provided by (used in) operating activities

Net cash used in operating activities for the six months ended June 30, 2013 was $10.0 million , compared to cash provided by operating activities of $64.8 million for the same period ended June 30, 2012 . The decrease of $74.8 million in net cash flows from operating activities is primarily due to higher uses of working capital. The increase in revenues noted above have resulted in the related growth of accounts receivable balances. In addition, there were increases in cash paid for taxes resulting from the improved operating results.

Net cash used in investing activities

Net cash used in investing activities for the six months ended June 30, 2013 was $67.5 million , an increase of $62.3 million from the same period ended June 30, 2012 . The increase in cash used is due to the cash payment of $77.2 million for the acquisition of Refusol. Capital expenditures for the three and six months ended June 30, 2013 were down $0.4 million compared to the same period in 2012 . We expect to fund future capital expenditures with cash generated from operations.

Net cash provided by (used in) financing activities

Net cash provided by financing activities in the six months ended June 30, 2013 was $17.8 million , a $73.8 million change from the cash used in financing activities of $56.0 million in the same period of 2012 . The exercise of stock options provided

Table Of Contents

$16.9 million of cash in 2013 as compared to $1.6 million in 2012 . The six months ended June 30, 2012 included stock repurchases of $57.1 million while no repurchases have been made in 2013.

Effect of currency translation on cash

During the six months ended June 30, 2013 , currency translation had a positive $0.2 million impact on cash compared to a negative impact of $1.0 million in the same period of 2012 . The functional currencies of our worldwide operations primarily include U.S. dollar ("USD"), Japanese Yen ("JPY"), Chinese Yuan ("CNY"), New Taiwan Dollar ("TWD"), South Korean Won ("KRW"), British Pound ("GBP"), Swiss Franc ("CHF"), Canadian Dollar ("CAD") , Euro ("EUR"), and Indian Rupee ("INR"). Our purchasing and sales activities are primarily denominated in USD, JPY, CNY, and EUR. The change in these key currency rates during the six months ended June 30, 2013 and 2012 are as follows:



		Six Months Ended June 30,
From	To	2013		2012
CNY	USD	1.1	%	(0.8	)%

CAD	USD	(5.7	)%	(0.1	)%
CHF	USD	(3.1	)%	(1.7	)%
INR	USD	(7.7	)%	(2.7	)%

Off Balance Sheet Arrangements

We have no off-balance sheet arrangements or variable interest entities.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with U.S. GAAP requires us to make judgments, assumptions and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Note 1 to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2012 describes the significant accounting policies and methods used in the preparation of our Consolidated Financial Statements. Our critical accounting estimates, discussed in the Management's Discussion and Analysis of Financial Condition and Results of Operations in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2012 , include estimates for allowances for doubtful accounts, determining useful lives for depreciation and amortization, the valuation of assets and liabilities acquired in business combinations, assessing the need for impairment charges for identifiable intangible assets and goodwill, establishing warranty reserves, accounting for income taxes, and assessing excess and obsolete inventories. Such accounting policies and estimates require significant judgments and assumptions to be used in the preparation of the Condensed Consolidated Financial Statements and actual results could differ materially from the amounts reported based on variability in factors affecting these estimates.

Our management discusses the development and selection of our critical accounting policies and estimates with the Audit Committee of our Board of Directors at least annually. Our management also internally discusses the adoption of new accounting policies or changes to existing policies at interim dates, as it deems necessary or appropriate.


ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our market risk exposure relates to changes in interest rates in our investment portfolio and credit facility. We generally place our investments with high-credit quality issuers and by policy are averse to principal loss and seek to protect and preserve our invested funds by limiting default risk, market risk, and reinvestment risk.

Table Of Contents

As of June 30, 2013 , our investments consisted primarily of certificates of deposit, municipal bonds, and institutional money markets, all with maturity of less than 2 years. As a measurement of the sensitivity of our portfolio and assuming that our investment portfolio balances remain constant, a hypothetical decrease of 100 basis points (1%) in interest rates would decrease annual pre-tax earnings by approximately $0.1 million .

We had $13.4 million of debt outstanding as of June 30, 2013 under various debt instruments, some with variable interest rates and principal payments. Assuming a full drawdown on all outstanding loan agreements subject to variable interest rates, and holding other variables constant, a hypothetical immediate one percentage point change in interest rates would be expected to have an impact on pre-tax earnings and cash flows of approximately $0.5 million over the course of 12 months.

Foreign Currency Exchange Rate Risk

We are impacted by changes in foreign currency exchange rates through sales and purchasing transactions when we sell products and purchase materials in currencies different from the currency in which product and manufacturing costs were incurred. Our purchasing and sales activities are primarily denominated in the USD, JPY, CNY and EUR. As these currencies fluctuate against each other, and other currencies, we are exposed to foreign currency exchange rate risk on sales, purchasing transactions and labor.

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

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

Currency exchange rates vary daily and often one currency strengthens against the USD while another currency weakens. Because of the complex interrelationship of the worldwide supply chains and distribution channels, it is difficult to quantify the impact of a change in one or more particular exchange rates.

See the "Risk Factors" set forth in Part I, Item 1A of our Annual Report on Form 10-K for more information about the market risks to which we are exposed. There have been no material changes in our exposure to market risk from December 31, 2012 .


ITEM 4.	CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures, which are designed to ensure that information required to be disclosed in reports filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. These disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports that we file or submit under the Act is accumulated and communicated to management, including our Principal Executive Officer (Garry Rogerson, Chief Executive Officer) and Principal Financial Officer (Danny C. Herron, Executive Vice President & Chief Financial Officer), as appropriate, to allow timely decisions regarding required disclosures.

As of the end of the period covered by this report, we conducted an evaluation, with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures pursuant to the Exchange Act Rule 13a-15(b). Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2013 . The conclusions of the Chief Executive Officer and Chief Financial Officer from this evaluation were communicated to the Audit Committee. We intend to continue to review and document our disclosure controls and procedures, including our internal controls and procedures for financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

Changes in Internal Control over Financial Reporting

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

As discussed in Note 2, Business Acquisition and Disposition, to our Condensed Consolidated Financial Statements, on April 8, 2013, we acquired Refusol. We considered the results of our pre-acquisition due diligence activities, the continuation by Refusol of their established internal control over financial reporting, and our implementation of additional internal control over financial reporting activities as part of our overall evaluation of disclosure controls and procedures as of June 30, 2013. We believe the design of Refusol's established internal control over financial reporting is sufficiently different from our overall design and the controls implemented to integrate Refusol's financial operations into our existing operations constitute a change in internal controls. We are in the process of completing a more complete review of Refusol's internal control over financial reporting and will be implementing changes to better align its reporting and controls with the rest of Advanced Energy. As a result of the timing of the acquisition and the changes that are anticipated to be made, we currently intend to exclude Refusol from the December 31, 2013 assessment of our internal control over financial reporting.

We are involved in disputes and legal actions arising in the normal course of our business.

There have been no material developments in legal proceedings in which we are involved during the quarter ended June 30, 2013 . For a description of previously reported legal proceedings refer to Part I, Item 3, "Legal Proceedings" of our Annual Report on Form 10-K for the year ended December 31, 2012 .


ITEM 1A.	RISK FACTORS

Item 1A, "Risk Factors," of our Annual Report on Form 10-K for the year ended December 31, 2012 describes some of the risks and uncertainties associated with our business. The risk factors set forth below update such disclosures. Other factors may also exist that we cannot anticipate or that we currently do not consider to be significant based on information that is currently available. These risks and uncertainties have the potential to materially affect our business, financial condition, results of operations, cash flows and future results. Such risks and uncertainties also may impact the accuracy of forward-looking statements included in this Form 10-Q and other reports we file with the Securities and Exchange Commission.

Activities necessary to integrate acquisitions may result in costs in excess of current expectations or be less successful than anticipated.

As noted in

Note 2. Business Acquisitions and Disposition in Part I Item 1 of this Form 10-Q, we recently acquired Refusol Holding GmbH, and we may acquire other businesses in the future. The success of such transactions will depend on, among other things, our ability to integrate assets and personnel acquired in these transactions and to apply our internal controls process to these acquired businesses. The integration of acquisitions may require significant attention from our management, and the diversion of management's attention and resources could have a material adverse effect on our ability to manage our business. Furthermore, we may not realize the degree or timing of benefits we anticipated when we first entered into the acquisition transaction, or the acquired business may cause us to incur unanticipated costs or liabilities. If actual integration costs are higher than amounts originally anticipated, if we are unable to integrate the assets and personnel acquired in an acquisition as anticipated, if we are unable to benefit from anticipated sales, or if we are unable to fully benefit from anticipated synergies, our business, financial condition, results of operations and cash flows could be materially adversely affected.

There are increased risks associated with restructuring plans and transferring further activities to our Shenzhen, China and Pune, India facilities.

As part of our April 2013 restructuring plan, we are taking steps to reduce operating costs across the company. These steps include transferring even more of our various operating activities, such as supply chain management, manufacturing, engineering and other activities, to our Shenzhen, China facility. This means that we will be even more highly dependent on our China-based operations. Given our recent acquisition of Refusol, we are also looking at ways to reduce our operating costs by transferring activities to their Pune, India facility. Such concentration exposes us to political, labor, culture, currency, tax, customs and other various risks unique to those regions. These risks may have a material adverse effect on our operations, business, results of operations, and financial condition.

We must continually design and introduce new products into the markets we serve to respond to competition and rapid technological changes.

As we operate in a highly competitive environment where innovation is critical, our future success depends on many factors, including the effective commercialization and customer acceptance of our products and services. The development, introduction and support of a broadening set of products (such as the recent introduction of our 1 megawatt solar inverter) is critical to our continued success. Our results of operations could be adversely affected if we do not continue to develop new products, improve and develop new applications for existing products, and differentiate our products from those of competitors resulting in their adoption by customers.
