     In the opinion of management, the accompanying unaudited condensed consolidated balance sheets; statements of income; stockholders’ equity and comprehensive income; and cash flows contain all adjustments, consisting of normal, recurring adjustments necessary to present fairly the financial position of Advanced Energy Industries, Inc., a Delaware corporation, and its wholly owned subsidiaries (the “Company”) at June 30, 2008 and December 31, 2007, and the results of their operations for the three and six month periods ended June 30, 2008 and 2007 and cash flows for the six month periods ended June 30, 2008 and 2007.

     The unaudited condensed consolidated financial statements presented herein have been prepared in accordance with the instructions to Form 10-Q and do not include all the information and note disclosures required by accounting principles generally accepted in the United States. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2007.

     SEGMENT REPORTING — The Company operates in one segment for the manufacture, marketing and servicing of key products, primarily to the semiconductor capital equipment industry, in accordance with Statement of Financial Accounting Standard (“SFAS”) No. 131, “Disclosures About Segments of an Enterprise and Related Information”. Since the Company operates in one segment, all financial information required by SFAS No. 131 can be found in the condensed consolidated financial statements and notes thereto.

     ESTIMATES AND ASSUMPTIONS — The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States requires the Company’s management to make estimates and assumptions 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. Significant estimates are used when establishing allowances for doubtful accounts; determining useful lives for fixed assets and intangible assets; assessing the need for impairment charges; establishing warranty reserves; establishing the fair value and forfeiture rate of stock-based compensation; estimating the fair value of financial instruments; accounting for income taxes; and assessing excess and obsolete inventory and various other items. The Company evaluates these estimates and judgments on an ongoing basis and bases its estimates on historical experience, current conditions and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Actual results may differ from these estimates under different assumptions or conditions.

     NEW ACCOUNTING PRONOUNCEMENTS — We adopted the provisions of SFAS No. 157, “Fair Value Measurements” (“FAS 157”) on January 1, 2008. FAS 157 defines fair value, establishes a market-based framework or hierarchy for measuring fair value, and expands disclosures about fair value measurements. FAS 157 is applicable whenever another accounting pronouncement requires or permits assets and liabilities to be measured at fair value. FAS 157 does not expand or require any new fair value measures, however the application of this statement may change current practice. In February 2008, the FASB decided that an entity need not apply this standard to nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis until 2009. Accordingly, our adoption of this standard in 2008 was limited to financial assets and liabilities, which primarily affects the valuation of our derivative contracts and marketable securities.

     We adopted SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities - - Including an Amendment of FASB Statement No. 115” (“FAS 159”) on January 1, 2008. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value. Entities that elect the fair value option will report unrealized gains and losses in earnings at each subsequent reporting date. The fair value option may be elected on an instrument-by-instrument basis, with few exceptions. FAS 159 also establishes presentation and disclosure requirements to facilitate comparisons between companies that choose different measurement attributes for similar assets and liabilities. The adoption of FAS 159 did not have an effect on our financial condition or results of operations as we did not elect this fair value option for any of our financial assets or liabilities, nor is it expected to have a material impact on future periods as the election of this option for our financial instruments is expected to be limited.

     REVENUE RECOGNITION — The Company’s product revenue is recognized when title passes to the customer, at either shipment, delivery or customer acceptance based on the terms of the sale. The Company’s post sale obligations are limited to product warranty obligations. In limited instances the Company provides installation of its products. In accordance with Emerging Issues Task Force Issue 00-21 “Accounting for Revenue Arrangements With Multiple Deliverables”, the Company allocates revenue based on the fair value of the delivered item, generally the product, and the undelivered item, installation, based on their respective fair values. Revenue related to the undelivered item is deferred until the services have been completed.

     In certain instances, based on the credit terms with the customer, the Company requires its customers to pay for a portion or all of their purchases prior to the Company building or shipping these products. Cash payments received prior to shipment are recorded as customer deposits and deferred revenue in the condensed consolidated balance sheets, and then recognized as revenue as appropriate based upon the transfer of title of the products. The Company does not offer price protection to customers, or allow returns, unless covered by our normal policy for repair of defective products.

     WARRANTY RESERVE POLICY — The Company offers product warranty coverage for periods typically ranging from 12 to 24 months after shipment. The Company estimates the anticipated costs of repairing products under warranty based on the historical cost of the repairs. The assumptions used to estimate the warranty reserve are reviewed periodically based on actual experience and, when appropriate, the warranty reserve is adjusted. Estimated warranty costs are recorded at the time of sale and are reflected in cost of sales in the consolidated statements of income.

     The following table summarizes the activity in the Company’s warranty reserve during the three and six months ended June 30, 2008 and 2007:

     EXCESS AND OBSOLETE INVENTORY— Inventory is evaluated regularly for usability, and if it is deemed as excess or obsolete, it is written down or written off accordingly. Estimating the net realizable value of inventory is based primarily upon forecasts of product demand. Charges for excess and obsolete inventory are recorded, as necessary, within cost of sales in the consolidated statements of income.

     COMMITMENTS AND CONTINGENCIES — The Company is subject to disputes and legal actions arising in the normal course of its business. The Company accrues loss contingencies in connection with its commitments and contingencies, when it is probable that a loss has occurred or may occur and the amount of the loss can be reasonably estimated. Loss contingencies may include, but are not limited to, litigation and contractual obligations.

     GOODWILL AND OTHER INTANGIBLE ASSETS — Goodwill represents the excess of the cost over the fair market value of net tangible and identifiable intangible assets of acquired businesses.

     Goodwill is subject to periodic (at least annual) tests for impairment. Impairment testing is performed in two steps: (i) goodwill is assessed for potential impairment by comparing the fair value of the Company’s reporting unit with the carrying value, and (ii) if potential impairment is indicated because the reporting unit’s fair value is less than its carrying amount, the amount of impairment loss is measured by comparing the implied fair value of goodwill with the carrying amount of that goodwill.

     Finite-lived intangible assets are amortized using the straight-line method over their estimated useful lives and are reviewed for impairment whenever events or circumstances indicate that their carrying amount may not be recoverable.

     The Company recognizes stock-based compensation expense in accordance with the provisions of Statement of Financial Accounting Standards No. 123R (“FAS 123R”), “Share-Based Payment”. Stock-based compensation was $1.3 million and $992,000 for the three months ended June 30, 2008 and 2007, respectively and $1.8 million for the six months ended June 30, 2008 and 2007, respectively.

     A summary of our stock option activity for the six month period ended June 30, 2008 is as follows:

     The total intrinsic value of options exercised during the three and six months ended June 30, 2008 was $758,000 and $748,000, respectively, and was $1.6 million and $2.8 million for the three and six months ended June 30, 2007, respectively, determined as of the exercise date. As of June 30, 2008, there was $13.5 million of total unrecognized compensation cost related to stock options granted and outstanding, which is expected to be recognized through fiscal year 2012, with a weighted average remaining vesting period of 3.0 years. Cash received from stock option exercises was $1.2 million during both the three and six months ended June 30, 2008. The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

     A summary of the Company’s non-vested Restricted Stock (“RSU”) activity for the six month period ended June 30, 2008 is as follows:

     The fair value of the Company’s RSUs is determined based upon the closing fair market value of the Company’s common stock on the grant date. At June 30, 2008, there was $5.2 million of total unrecognized compensation cost related to non-vested RSUs outstanding, which cost is expected to be recognized over a weighted average period of 1.7 years. During the quarter ended June 30, 2008, the total fair value of RSUs which vested was $534,000, based upon the closing fair market value of the Company’s common stock on the date the underlying common stock was released to the recipient.

     During the three months ended June 30, 2008, 15,000 shares were granted under the ESPP. As of June 30, 2008, there was $38,000 of total unrecognized compensation cost related to the ESPP that is expected to be recognized over a remaining period of two months.

          Upon adoption of FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No 109” (“FIN 48”) as of January 1, 2007, the Company increased the long-term liability associated with uncertain tax positions by $6 million and also increased the long-term receivable of $5 million consisting of offsetting tax benefits. As of December 31, 2007, the balance of our tax contingencies was $5.8 million. If the $5.8 million of tax contingencies reverse, $1.1 million would affect our effective tax rate. There have been no significant changes to these amounts during the quarter or six months ended June 30, 2008.

     The tax years 2003 through 2007 remain open to examination by the U.S. state and local taxing jurisdictions to which we are subject. The tax years 2004 through 2007 remain open to examination by the U.S. Internal Revenue Service. The foreign taxing jurisdictions have open tax years from 2001 through 2007. In accordance with our accounting policy, we recognize accrued interest and penalties related to unrecognized tax benefits as a component of tax expense. We did not have any accrued interest or penalties at December 31, 2007 or June 30, 2008. We do not anticipate a material change to the amount of unrecognized tax positions within the next 12 months.

     The Company’s expected tax rate is projected to be 27% for the year ended December 31, 2008, approximately 4% lower than the Company’s tax rate for the year ended December 31, 2007. The Company expects a favorable profit mix for tax purposes for its subsidiaries as more income is expected to be generated by our subsidiaries in lower income tax jurisdictions. Additionally, in 2008, the tax rate in Germany, where a portion of our profits are reported, was lowered from 39% to 30% where a portion of our profits are reported.

     While we believe we have adequately provided for all of our tax positions, amounts asserted by taxing authorities could materially differ from our accrued positions as a result of uncertain and complex application of tax regulations. Additionally, the recognition and measurement of certain tax benefits includes estimates and judgment by management and inherently includes subjectivity. Accordingly, additional provisions on federal and foreign tax-related matters could be recorded in the future as revised estimates are made or the underlying matters are settled or otherwise resolved. We do not believe any federal or foreign tax-related matters warrant additional provisions as of June 30, 2008.

     On March 5, 2008, the Company restructured a portion of its administrative operations. Related to this, the Company recorded restructuring charges of $393,000 and $1.07 million during the three and six month periods ended June 30, 2008, respectively, for severance costs. The Company expects to recognize an additional $185,000 related to this restructuring for severance and benefit costs through November 2008.

     In March 2007, the Company announced the closure of its operation located in Stolberg, Germany. Related to this closure, the Company recorded restructuring charges of $2.95 million, as of June 30, 2007, consisting primarily of $2.05 million for the accrual of employee severance and benefit costs associated with the reduction of employees at the facility and an asset impairment charge of approximately $900,000 related to the write-down of certain real and personal property to their estimated fair value.

     Investment securities with original maturities of more than three months at time of purchase are considered marketable securities. Marketable securities as of June 30, 2008 included certificates of deposit, municipal bonds and notes, institutional money markets and auction rate securities. The Company’s investments are classified as available for sale securities, and are recorded at fair value with temporary changes in fair market value recorded as unrealized holding gains or losses in other comprehensive income (loss), net of tax.

     The Company’s investments, both current and non-current, are carried at their fair value as further described in Note 14. For purposes of determining realized gains and losses, the cost of securities sold is based on specific identification. The composition of securities, classified as current and non-current assets is as follows at June 30, 2008, and December 31, 2007:

     Auction rate securities are debt instruments with long-term scheduled maturities, but have interest rates that are typically reset at pre-determined intervals, usually every 7, 28, 35 or 90 days, at which time the securities can typically be purchased or sold. Starting in February 2008, the Company experienced difficulty in selling these securities due to the failure of the auction mechanism which historically provided liquidity to these securities. The securities for which auctions have failed will continue to accrue interest and be auctioned every 35 days until the auction succeeds, the issuer calls the securities for redemption, or they mature. Accordingly, there may be no effective mechanism for selling these securities. In the first quarter of 2008, the Company reclassified the entire auction rate security investment balance from marketable securities to long-term investments on its condensed consolidated balance sheet because of the Company’s inability to determine when its investments in auction rate securities would settle. As of June 30, 2008, the Company recorded a temporary impairment of $1.7 million, net of taxes in other comprehensive income for its auction rate securities.

     Accounts receivable consisted of the following:

     Inventories consisted of the following:

     Inventories include costs of materials, direct labor and manufacturing overhead. Inventories are valued at the lower of cost or market and computed on a first-in, first-out basis.

     Goodwill and amortizable intangible assets consisted of the following as of June 30, 2008:

     Goodwill and amortizable intangible assets consisted of the following as of December 31, 2007:

     Amortization expense related to intangible assets for the three months ended June 30, 2008 and 2007 was $226,000 and $202,000, respectively, and $466,000 and $526,000 for the six months ended June 30, 2008 and 2007, respectively. Estimated amortization expense related to the Company’s acquired intangible assets fluctuates with changes in foreign currency exchange rates between the U.S. dollar, the Japanese yen and the euro. Estimated amortization expense related to amortizable intangibles for each of the five years 2008 through 2012 is as follows:

     Stockholders’ equity consisted of the following:

     On December 24, 2007, the Board of Directors authorized a program to repurchase up to $75 million of our common stock over a 12 month period. Purchases under the program may be made from time-to-time in the open market, through privately negotiated transactions, through block trades, Rule 10b5-1 trading plans or other available means. There is no minimum or maximum number of shares that may be repurchased under the program and the program may be discontinued at any time, without prior notice. During the three and six month periods ended June 30, 2008, we repurchased and retired 1,031,000 and 3,775,000 shares, respectively, of our common stock at an average market price of $13.75 and $13.24 per share respectively in such periods. All shares repurchased were executed in the open market and no shares were repurchased from related parties. Repurchased shares were retired and assumed the status of authorized and unissued shares.

     On April 22, 2008, the Company suspended its stock repurchase program previously announced December 27, 2007.

     Comprehensive income (loss) for the Company consists of net income, foreign currency translation adjustments and net unrealized holding gains (losses) on available-for-sale marketable securities and non-current investments as presented below (In thousands):

     We are involved in disputes and legal actions from time to time in the ordinary course of our business.

     On April 9, 2008, the Company was served with a complaint filed on December 20, 2007 in the U.S. District Court for the Western District of Texas by Celerity, Inc., alleging infringement by the Company’s PI-980 Mass Flow Controller product of 5 U.S. patents owned by Celerity and seeking injunctive and monetary relief. Celerity voluntarily dismissed the complaint on July 14, 2008.

     Between January 15 and April 28, 2008, the Customs Office of Taipei, Taiwan issued a series of orders to the Company’s Taiwanese subsidiary, Advanced Energy Taiwan, Ltd., requiring that certain Company products manufactured in mainland China and allegedly imported without proper authorization be removed from Taiwan. The Company has protested the orders based upon recent rulings of the Taiwan Bureau of Foreign Trade that the products were authorized for unrestricted import. The Company believes that even if its protest is unsuccessful, the cost of compliance with the orders would be immaterial to the Company’s operations.

     On November 5, 2007, a complaint was filed in the U.S. District Court for the District of Colorado by Xantrex Technology, Inc., alleging various breaches of confidence and interference with contractual duties in connection with the Company’s hiring of a former employee of Xantrex. Xantrex sought injunctive relief against both the Company and its former employee, and the Company filed a motion to dismiss all claims. A hearing on the cross motions was held on January 18 and 22, 2008. On May 23, 2008, the District Court denied the Company’s motion to dismiss and granted injunctive relief to Xantrex. The Company has filed an appeal with the Tenth Circuit Court of Appeals. The matter is proceeding in the District Court while the appeal is pending. The Company does not expect the proceedings to result in any material adverse impact on our business or financial results.

     The Company has firm purchase commitments and agreements with various suppliers to ensure the availability of components. The obligation at June 30, 2008 under these arrangements is approximately $32.3 million. Substantially all amounts under these arrangements are due in 2008. Actual expenditures will vary based upon the volume of the transactions and length of contractual service provided. In addition, the amounts paid under these arrangements may be less in the event that the arrangements are renegotiated, settled, or cancelled. Certain agreements provide for potential cancellation penalties. The Company’s policy with respect to all purchase commitments is to record losses, if any, when they are probable and reasonably estimable and believes it has adequate provision for potential exposure related to inventory on order which may go unused.

     As of June 30, 2008, stock options and restricted stock units relating to an aggregate of approximately 4.0 million shares were outstanding, and, as of June 30, 2007, stock options and restricted stock units relating to an aggregate of approximately 3.4 million shares were outstanding. Not included in the computation of diluted earnings per share are stock options in respect of 3.6 million shares for the three months ended June 30, 2008, stock options in respect of 2.6 million shares for the three months ended June 30, 2007, stock options in respect of 3.6 million shares for the six months ended June 30, 2008, and stock options in respect of 2.7 million shares for the six months ended June 30, 2007, respectively due to the anti-dilutive effect of these shares.

     The following is a reconciliation of the numerator and denominator used in the calculation of basic and diluted EPS for the three and six month periods ended June 30, 2008 and 2007:

     The Company has operations in the United States, Asia Pacific and Europe. The following is a summary of the Company’s operations by geographic region:

     Intercompany sales between the Company’s geographic areas are recorded on the basis of intercompany prices established by the Company.

     Applied Materials, Inc. is the Company’s largest customer and accounted for 23% and 28% of the Company’s sales for the three months ended June 30, 2008 and 2007, respectively and 24% and 29% for the six months ended June 30, 2008 and 2007, respectively. No other customer accounted for 10% or more of the Company’s sales during these periods.

     As stated in “—Note 1. Basis of Presentation And Summary of Significant Accounting Policies”, on January 1, 2008, the Company adopted the methods of fair value measurement as described in FAS No. 157 to value its financial assets and liabilities. As defined in FAS No. 157, fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, FAS No. 157 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:

     Determining where an asset or liability falls within the hierarchy depends on the lowest level input that is significant to the fair value measurement as a whole. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and considers counterparty credit risk in the assessment of fair value.

     Financial assets and liabilities carried at fair value as of June 30, 2008 are classified in the table below in one of the three categories described above:

     Due to the lack of observable market quotes on the Company’s auction rate securities portfolio, the Company utilizes a valuation model that relies exclusively on Level 3 inputs including market, tax status, credit quality, duration, recent market observations and overall capital market liquidity. The valuation of the Company’s auction rate securities is subject to uncertainties that are difficult to predict. Factors that may impact the Company’s valuation include changes to credit ratings of the securities as well as to the underlying assets supporting those securities, rates of default of the underlying assets, underlying collateral value, discount rates, counterparty risk and ongoing strength and quality of market credit and liquidity. Auction rate securities totaling approximately $3.9 million were liquidated, sold or recalled in the second quarter of 2008. The Company concluded that the fair value of the remaining auction rate securities at June 30, 2008 was $34.3 million, a decline of $2.3 million from par value during the six months ended June 30, 2008. The decline in fair value from December 31, 2007 was deemed temporary as the Company believes the decline in fair value of these investments is due to general market conditions, and the Company has the intent and ability to hold these investments until anticipated recovery in fair value occurs. Accordingly, the Company recorded the unrealized decline in fair value, net of tax, on these securities of $1.7 million in other comprehensive income.

     The Company continues to monitor the market for auction rate securities and consider its impact (if any) on the fair value of its investments. If the current market conditions deteriorate further, if a secondary market emerges for these securities, or if the anticipated recovery in fair values does not occur, the Company may be required to record additional losses.

     The following discussion contains, in addition to historical information, 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. Statements that are other than historical information are forward-looking statements. For example, statements relating to our beliefs, expectations and plans are forward-looking statements, as are statements that certain actions, conditions or circumstances will continue. Forward-looking statements involve risks and uncertainties, which are difficult to predict and many of which are beyond our control. Some of these risks and uncertainties are described in Part II Item 1A below and in other filings we make with the Securities and Exchange Commission, including our Annual Report on Form 10-K for the year ended December 31, 2007. As a result, our actual results may differ materially from the results discussed in the forward-looking statements. We assume no obligation to update any forward-looking statements or the reasons why our actual results might differ.

     We design, manufacture and support complex power conversion and control systems, and gas flow control and thermal measurement devices used in plasma-based, thin-film processing equipment. This equipment is essential to the manufacture of products as follows:

     We also design, manufacture and support commercial grade inverters for the solar power market which convert power generated by solar panels into usable power.

     Our global network of service centers provides local repair and field service capability in key regions. Our installed base provides a recurring revenue opportunity as we sell repair services, conversions, upgrades and refurbishments.

     We provide solutions to a diverse range of markets and geographic regions with the semiconductor capital equipment industry being our largest market and sales to the solar market being our second largest market. Sales to customers in the semiconductor capital equipment industry comprised 52% and 66% of our sales in the three months ended June 30, 2008 and 2007, respectively and 58% and 69% of our sales in the six months ended June 30, 2008 and 2007, respectively. Demand in the semiconductor capital equipment market has weakened over the past year and as such our revenues to that market have dropped. This cyclical downturn was the result of excess capital spending in 2006 and 2007 in the semiconductor market followed by a lack of spending in the market in 2008. Sales to customers in the solar market comprised 14% and 6% of our sales in the three months ended June 30, 2008 and 2007, respectively, and 12% and 6% of our sales in the six months ended June 30, 2008 and 2007, respectively. The investments in capacity for solar panel production lines have driven this growth in revenue. Our products are aligned with the polysilicon, copper indium gallium selenide (CIGS), copper indium selenide (CIS), cadmium telluride, and thin-film solar production processes. Other markets we sell to include flat panel display, data storage, architectural glass, and other industrial thin-film manufacturing equipment. Our customers in these markets are predominatly large original equipment manufacturers (OEM’s) for new equipment and we also derive additional revenue from our installed base by providing services to the end manufacturer. Our solar inverter revenue is included in our sales to the solar market.

     Sales for the second quarter of 2008 were $88.0 million, a 14.6% decrease compared to second quarter 2007 sales of $103.0 million. In the second quarter of 2008, we generated net income from operations of $6.9 million, or 7.9% of sales, compared to the second quarter of 2007, when we generated net income from operations of $16.3 million, or 15.8% of sales. Gross margin decreased to 40.1% in the first quarter of 2008 from 43.6% in the second quarter of 2007. We generated earnings of $0.14 per diluted share in the second quarter of 2008 compared to $0.25 per diluted share in the second quarter of 2007.

     The following tables summarize our unaudited net sales and percentages of net sales by semiconductor and non-semiconductor markets for the three and six month periods ended June 30, 2008 and 2007:

     The following tables summarize our unaudited net sales and percentages of net sales by geographic region for the three and six month periods ended June 30, 2008 and 2007:

     Sales were $88.0 million in the second quarter of 2008, a decrease of 14.6% compared to sales of $103.0 million in the second quarter of 2007. Our sales to the semiconductor capital equipment industry decreased approximately 33% compared to the second quarter of 2007, and decreased approximately 29% compared to the six months ended June 30, 2007. The decline was due to a reduction in demand from the semiconductor capital equipment industry as capital spending in the first half of 2007 for capacity expansion was strong. Demand in 2008 has reduced as semiconductor manufacturers absorb the capacity that they added in 2006 and 2007. Overall semiconductor manufacturers are optimizing the output from their installed capacity and are finding ways to improve output without spending capital on expansion. Sales to the markets outside of the semiconductor capital equipment market grew 22% which partially dampened the effect of the decline in the semiconductor capital equipment market. Sales to the solar market were strong as solar panel manufacturers invested in capacity expansion for solar panel production. Revenues to the solar market grew to 14% for the second quarter of 2008. Sales to the flat panel display market grew as well, as the leading flat panel display manufactures continued their investments in additional capacity. Our other non-semi markets showed growth which resulted in a shift in the balance of our business to 52% semi and 48% non-semi in the second quarter. This mix of revenues has been in the range of 67% semi and 37% non-semi in the past several quarters.

     Our gross profit was 40.1% and 40.2% in the three and six months ended June 30, 2008, compared to 43.6% and 44.3% in the three and six months ended June 30, 2007. The decline in revenues caused a lower absorption of our fixed costs which caused the decline decrease in our gross margin.

     The markets for our products constantly present us with opportunities to develop our products for new or emerging applications, along with requirements for technological changes driving for higher performance, lower cost, and other attributes that will 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, is 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. Since inception, all of our research and development costs have been expensed as incurred.

     Our research and development expenses were $13.8 million, or 15.6% of sales, in the second quarter of 2008 and $12.9 million, or 12.5% of sales, in the second quarter of 2007. The 6.6% increase from 2007 to 2008 was primarily due to increased efforts in the development of solar products and our inverter product line. We expect to continue these investments in order to deliver an expanded product suite to the solar equipment market as well as the solar inverter market.

     Our global sales and marketing activities comprise our selling expenses, which 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, patent, tax, financial, governance, administrative, information systems and human resource functions in addition to our general management.

     Selling, general and administrative (“SG&A”) expenses were $13.9 million, or 15.8% of sales, for the second quarter of 2008 and $15.4 million, or 15.0% of sales, for the second quarter of 2007. The $1.5 million decrease in SG&A expenses from 2007 to 2008 was primarily due to the ongoing implementation of our cost reduction program in the second quarter and $300,000 for the reversal of bad debt expense related to a balance that was collected in the second quarter. We expect the effect of the cost reduction efforts to continue through the end of the year. Partially offsetting these decreases, SG&A expenses in the second quarter included approximately $400,000 in legal fees related to litigation on various matters.

     Restructuring charges of $393,000 were incurred in the three months ended June 30, 2008 and restructuring charges of $1.1 million were incurred during the six month period ended June 30, 2008. The charges were severance charges incurred as the result of restructuring a portion of our sales and administrative operations. We expect to incur additional restructuring costs in the second half of 2008 including $185,000 in connection with the restructuring announced in the first half of 2008.

     Our restructuring charges in the first and second quarters of 2007 were incurred in conjunction with the closing of our factory located in Stolberg, Germany. The closure of the facility was completed by October 31, 2007. Related to this closure, we recorded restructuring charges of $158,000 and $3.0 million during the three and six month periods ended June 30, 2007, respectively, consisting of employee severance and benefit costs and an asset impairment charge relating to the write-down to estimated fair value of certain real and personal property at the facility.

     Other income, net consists primarily of investment income and expense, foreign exchange gains and losses and other miscellaneous gains, losses, income and expense items. Other income decreased 33.8% to $996,000 in the three months ended June 30, 2008 from $1.5 million in the three months ended June 30, 2007, and other income decreased 38.7% to $1.9 million in the six months ended June 30, 2008 from $3.1 million in the six months ended June 30, 2007, primarily due to lower interest rates, decreased investment balance, and increased foreign exchange loss due to strengthening of the Japanese yen and the euro in relation to the U.S. dollar. As of June 30, 2008, we had $36.6 million in auction rates securities earning interest. Although these securities have been classified as long-term on our balance sheet, we expect them to earn interest at the rates on the face of the security. Any impairment charge pertaining to auction rate securities, if it is determined to be other than temporary impairment, will be recorded in other income in future quarters.

     The income tax provision for the three and six month periods ended June 30, 2008 was $2.1 million and $4.4 million, respectively, which represented an effective tax rate of 26.1% and 27.1%, respectively in such periods compared to $6.1 million and $12.9 million for the three and six month periods ended June 30, 2007, respectively, which represented an effective tax rate of 34.4% and 34.7%, respectively in such periods. The decrease in the effective tax rate resulted primarily from a lower tax rate in Germany’s decrease of its tax rate from 39% to 30%. We expect that, for the balance of 2008, a greater portion of our income, as compared to 2007, will continue to be generated at our subsidiaries in jurisdictions with lower tax rates.

     At June 30, 2008, our principal sources of liquidity consisted of cash, cash equivalents and marketable securities of $139.7 million. In addition, we have auction rate securities of $34.3 million resulting in total invested cash of $175.7 million. During the six months ended June 30, 2008, following the reclass of $34.3 million in auction rates securities and $50 million in the repurchase of company stock, our cash, cash equivalents and marketable securities decreased $65.5 million, or 31.9%, from $205.3 million at December 31, 2007. Our working capital decreased $77.6 million, or 25%, to $228.4 million at June 30, 2008 from $306.0 million at December 31, 2007 primarily due to the reclass of the auction rate securities to long-term investments and the stock repurchase program.

     Our investment securities include auction rate securities that are not currently liquid or readily available to convert to cash. We do not believe that the current liquidity issues related to our auction rate securities will impact our ability to fund our ongoing business operations. However, if the global credit crisis persists or intensifies, it is possible that we will be required to further adjust the fair value of our auction rate securities. If we determine that the decline in the fair value of our auction rate securities is other than temporary, it would result in an impairment charge being recognized on our statement of income, which could be material and which could adversely affect our financial results. In addition, the lack of liquidity associated with these investments may require us to access our available lines of credit more frequently than otherwise until some or all of our auction rate securities are liquidated.

     Operating activities provided cash of $20.6 million in the six months ended June 30, 2008 primarily due to decreases in accounts receivable and inventory.

     Investing activities provided $36.2 million of cash in the six months ended June 30, 2008 and used $23.5 million in the six months ended June 30, 2007 primarily due to activity related to the sale of marketable securities. Capital expenditures in the first six months of 2008 were $3.9 million, compared to capital expenditures of $3.6 million in the first six months of 2007. We expect our total capital expenditures in 2008 to be approximately $8 to $10 million.

     Financing activities used cash of $48.6 million in the first six months of 2008 compared to cash provided of $4.1 million in the first six months of 2007 primarily due our purchase and retirement of treasury stock in the first six months of 2008.

     We believe that our working capital, together with cash anticipated to be generated by operations will be sufficient to satisfy our anticipated liquidity requirements for the next twelve months.

     In preparing our financial statements, we must make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ from these estimates under different assumptions or conditions.

     We believe that the following critical accounting policies, as discussed in this Form 10-Q and/or our Form 10-K for the year ended December 31, 2007, affect our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements:

     As of June 30, 2008, our investment securities currently include auction rate securities with a par value of $36.6 million, of which $30.4 million are tied to student loan debt and $6.2 million are tied to municipal debt. While the underlying securities commonly have long-term nominal maturities that exceed one year, the interest rates reset periodically in scheduled auctions (generally every 7-35 days). We have the opportunity to sell these investments during such periodic auctions subject to the availability of buyers. During the first six months of 2008, issues in the global credit and capital markets led to failed auctions with respect to a large portion of our auction rate securities. As a result, we recorded a $2.3 million unrealized loss ($1.7 million net of taxes) related to these investments

during the six month period ended June 30, 2008. We believe that we will be able to liquidate the investments at par within a reasonable time period. However, volatility in the credit markets could continue to negatively impact the liquidity of the investments and lead to additional adjustments to their carrying value. See Notes 5 and 14 to the Consolidated Condensed Financial Statements included in this Report and the “Risk Factors” set forth in Part II, Item 1A of this Report for more information. There were no additional material changes in the Company’s exposure to market risk from December 31, 2007.

     We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

     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, 2008. 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.

     There was no change in our internal control over financial reporting that occurred during our most recent quarter that has materially affected, or is reasonably likely to materially affect, the internal control over financial reporting.

     On April 9, 2008, the Company was served with a complaint filed on December 20, 2007 in the U.S. District Court for the Western District of Texas by Celerity, Inc., alleging infringement by the Company’s PI-980 Mass Flow Controller product of 5 U.S. patents owned by Celerity and seeking injunctive and monetary relief. Celerity voluntarily dismissed the complaint on July 14, 2008.

     Between January 15 and April 28, 2008, the Customs Office of Taipei, Taiwan issued a series of orders to the Company’s Taiwanese subsidiary, Advanced Energy Taiwan, Ltd., requiring that certain Company products manufactured in mainland China and allegedly imported without proper authorization be removed from Taiwan. The Company has protested the orders based upon recent rulings of the Taiwan Bureau of Foreign Trade that the products were authorized for unrestricted import. The Company believes that even if its protest is unsuccessful, the cost of compliance with the orders would be immaterial to the Company’s operations.

     On November 5, 2007, a complaint was filed in the U.S. District Court for the District of Colorado by Xantrex Technology, Inc., alleging various breaches of confidence and interference with contractual duties in connection with the Company’s hiring of a former employee of Xantrex. Xantrex sought injunctive relief against both the Company and its former employee, and the Company filed a motion to dismiss all claims. A hearing on the cross motions was held

on January 18 and 22, 2008. On May 23, 2008, the District Court denied the Company’s motion to dismiss and granted injunctive relief to Xantrex. The Company has filed an appeal with the Tenth Circuit Court of Appeals. The matter is proceeding in the District Court while the appeal is pending. The Company does not expect the proceedings to result in any material adverse impact on our business or financial results.

     We are involved in disputes and legal actions from time to time in the ordinary course of our business. For a description of the material pending legal proceedings to which we are a party, please see our 2007 Annual Report on Form 10-K, filed with the Securities and Exchange Commission on March 18, 2008 and Quarterly Report on Form 10-Q, filed with the Securities and Exchange Commission on May 9, 2008.

     Item 1A, “Risk Factors,” of our Annual Report on Form 10-K for the year ended December 31, 2007 describes some of the risks and uncertainties associated with our business. 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.

     Although we do not believe that there have been any material changes to the risk factors previously disclosed in the “Risk Factors” section of our Annual Report on Form 10-K, the risk factors set forth below have been updated with more current information.

     A significant portion of our sales is concentrated among a few customers.

     Our ten largest customers accounted for 49% and 51% of our total sales in the three and six months ended June 30, 2008, respectively and 51% and 55% of our total sales in the three and six months ended June 30, 2007, respectively. Applied Materials, Inc., our largest customer, accounted for 22% and 28% of our sales in the three month periods ended June 30, 2008 and 2007, respectively, and 24% and 29% for the six month periods ended June 30, 2008 and 2007, respectively. No other customer accounted for more than 10% of our sales during this period. The loss of any of our significant customers or a material reduction in any of their purchase orders could significantly harm our business, financial condition and results of operations.

     Market pressures may reduce or eliminate our profitability.

     Our customers continually exert pressure on us to reduce our prices and extend payment terms. Given the nature of our customer base and the highly competitive markets in which we compete, we may be required to reduce our prices or extend payment terms to remain competitive. We may not be able to reduce our expenses in an amount sufficient to offset potential margin declines.

     Funds associated with auction rate securities that we have traditionally held as short-term investments may not be liquid or readily available.

     As discussed previously in this Report, our investment securities include auction rate securities that are not currently liquid or readily available to convert to cash. We do not believe that the current liquidity issues related to our auction rate securities will impact our ability to fund our ongoing business operations. However, if the global credit crisis persists or intensifies or if a

secondary market results in lower values, it is possible that we will be required to further adjust the fair value of our auction rate securities. If we determine that the decline in the fair value of our auction rate securities is other than temporary, it would result in an impairment charge being recognized on our statement of income which could be material and which could adversely affect our financial results. In addition, the lack of liquidity associated with these investments may require us to access our available lines of credit more frequently until some or all of our auction rate securities are liquidated.

     On December 27, 2007, the Company announced a stock repurchase program under which the Company is authorized to acquire from time to time up to an aggregate of $75 million in Common Stock (the “Stock Repurchase Program”).

     Below is a summary of the Company’s purchases of its common stock during the first two quarters of 2008 under the Stock Repurchase Program.
