NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Organization and Significant Accounting Policies

Organization — Ultra Clean Holdings, Inc. (the “Company” or “UCT”) was founded in November 2002 for the purpose of acquiring Ultra Clean Technology Systems and Service Inc. Ultra Clean Technology Systems and Service, Inc. was founded in 1991 by Mitsubishi Corporation and was operated as a subsidiary of Mitsubishi until November 2002, when it was acquired by UCT. UCT became a publicly traded company in March 2004. In June 2006, the Company completed the acquisition of Sieger Engineering, Inc. to enhance its position as a subsystem supplier to the semiconductor, research, flat panel, energy and medical equipment industries. Ultra Clean Technology (Shanghai) Co., Ltd and Ultra Clean Micro-Electronics Equipment (Shanghai) Co., Ltd. were established in 2005 and 2007, respectively, to facilitate the Company’s operations in China. Ultra Clean Asia Pacific, Pte, Ltd. (Singapore) was established in fiscal year 2008 to facilitate the Company’s operations in Singapore. In July 2012, UCT acquired American Integration Technologies LLC (“AIT”) to add to the Company’s existing customer base in the semiconductor and medical spaces and to provide additional manufacturing capabilities. In November 2014, the Company launched Prototype Asia, its 3D printing business in Singapore, to develop additive manufacturing capabilities for the Company’s customer base. In February 2015, UCT acquired Marchi Thermal Systems, Inc. (“Marchi”), a designer and manufacturer of specialty heaters, thermocouples and temperature controllers. Marchi delivers flexible heating elements and thermal solutions to our customers. The Company believes heaters are increasingly critical in equipment design for the most advanced semiconductor nodes.

The Company is a global leader in the design, engineering, and manufacture of production tools, modules and subsystems for the semiconductor capital equipment industry and industry segments with similar requirements including consumer, medical and flat panel display. The Company focuses on providing specialized engineering and manufacturing solutions for these applications. The Company enables its customers to realize lower manufacturing costs and reduced design-to-delivery cycle times while maintaining high quality standards.

The Company provides its customers with complete solutions that combine its expertise in design, scan, assembly, test and component characterization. The Company’s customers value its highly flexible global manufacturing operations, its excellence in quality control and its scale and financial stability. The Company’s global footprint enables the Company to reduce manufacturing costs and design-to-delivery cycle times and maintains high quality standards for the Company’s customers. The Company believes that these characteristics allow the Company provides global solutions for its customers’ growing product demands. The Company ships the majority of its products to U.S. registered customers with locations both in and outside the U.S. In addition to its U.S. manufacturing capabilities, the Company manufactures products in its Asian facilities to support local and U.S. based customers. The Company conducts its operating activities primarily through its wholly owned subsidiaries, Ultra Clean Technology Systems and Service, Inc., AIT LLC, Ultra Clean Technology (Shanghai) Co., Ltd., Ultra Clean Micro-Electronics Equipment (Shanghai) Co., Ltd., Ultra Clean Asia Pacific, Pte Ltd. (Singapore), and subsequent to February 2, 2015, Marchi. The Company’s international sales represented 32.6% and 32.8% for the three months ended June 26, 2015 and June 27, 2014, respectively, and 32.2% and 29.0% of sales for the six months ended June 26, 2015 and June 27, 2014, respectively. See Note 9 to the Company’s Condensed Consolidated Financial Statements for further information about the Company’s geographic areas.

Basis of Presentation — The unaudited condensed consolidated financial statements included in this quarterly report on Form 10-Q include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). This financial information reflects all adjustments which are, in the opinion of the Company, normal, recurring and necessary to present fairly the statements of financial position, results of operations and cash flows for the dates and periods presented. Certain information and footnote disclosures normally included in our annual financial statements, prepared in accordance with GAAP, have been condensed or omitted. The Company’s December 26, 2014 balance sheet data were derived from its audited financial statements as of that date.

- 6 -

Principles of Consolidation — The Company’s condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and all intercompany accounts and transactions have been eliminated in consolidation. The Company uses a 52-53 week fiscal year ending on the Friday nearest December 31. All references to quarters refer to fiscal quarters and all references to years refer to fiscal years.

Foreign Currency Translation — The Company has reviewed its non-U.S. subsidiaries (of which all of its non-U.S. asset base resides in Asia) that operate in a local currency environment to determine their functional currency by examining how and in what currency each subsidiary generates cash through billings and cash receipts and how and in what currency the subsidiary expends cash through payment of its vendors and payment of its workforce. Also, these subsidiaries’ individual assets and liabilities that are primarily denominated in the local foreign currency are examined for their impact on the Company’s cash flows. All have been determined to have the U.S. dollar as its functional currency. Foreign currency transaction gains and losses are recorded in interest and other income (expense), net.

Use of Accounting Estimates — The presentation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates and assumptions include reserves on accounts receivable and inventory, valuation of deferred tax assets and impairment of goodwill and other long-lived assets. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, future events are subject to change and the best estimates and judgments may require adjustment. Actual amounts may differ from those estimates.

Certain Significant Risks and Uncertainties — The Company operates in a dynamic industry and, accordingly, can be affected by a variety of factors. For example, any of the following areas could have a negative effect on the Company in terms of its future financial position, results of operations or cash flows: the general state of the global economy, the highly cyclical nature of the industries the Company serves; the loss or bankruptcy of any customers within the Company’s small customer base; ability to obtain additional financing if needed; inability to meet certain debt covenants; failure to successfully integrate completed acquisitions; ineffectiveness in pursuing acquisition opportunities; regulatory changes; fundamental changes in the technology underlying semiconductor, flat panel, solar and medical device manufacturing processes or manufacturing equipment that the Company fails to be prepared for; the hiring, training and retention of key employees; successful and timely completion of product design efforts; and new product design introductions by competitors.

Concentration of Credit Risk — Financial instruments which subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company sells its products primarily to semiconductor capital equipment manufacturers in the United States. The Company performs credit evaluations of its customers’ financial condition and generally requires no collateral.

Significant sales to customers — The Company’s most significant customers (having accounted for 10% or more of sales) and their related sales as a percentage of total sales were as follows:


	Three months ended						Six months ended
	June 26, 2015			June 27, 2014			June 26, 2015			June 27, 2014
Lam Research Corporation		55.4	%		34.9	%		50.9	%		34.6	%
Applied Materials, Inc.		25.8			19.4			27.4			22.5
ASM International		—	*		17.1			—	*		18.3
GT Advanced Technologies (GTAT)		—	*		11.1			—	*		—	*

Total		81.2	%		82.5	%		78.3	%		75.4	%

*	Total sales for the period are below 10%.

Three customers’ accounts receivable balances, Applied Materials, Inc., Lam Research Corporation and ASM International, were individually greater than 10% of accounts receivable as of June 26, 2015, and in the aggregate represented approximately 83.4% of accounts receivable. Three customers’ accounts receivable balances, Applied Materials, Inc., Lam Research Corporation and ASM International, were individually greater than 10% of accounts receivable as of December 26, 2014, and in the aggregate represented approximately 73.7% of accounts receivable.

Fair Value of Financial Instruments — The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable and bank borrowings. The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximates their fair value because of their short-term nature.

The accounting guidance for fair value measurements prioritizes the inputs used in measuring fair value in the following hierarchy:

Level 1 — Quoted prices in active markets for identical assets or liabilities,

Level 2 — Observable inputs other than the Level 1 prices for similar assets or liabilities; quoted prices in active markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities,

Level 3 — Unobservable inputs in which there is little or no market data, and that are significant to the fair value of the assets or liabilities.

The Company’s only financial asset measured at fair value on a recurring basis is an overnight sweep account invested in money market funds with maturities of less than 90 days from purchase and is thus classified as cash and cash equivalents on the Company’s balance sheet. These money market funds had a carrying value and fair value of $3.8 million at June 26, 2015 based on Level 1 inputs. The fair value of the Company’s long term debt was based on level 2 inputs and fair value was determined using quoted prices for similar liabilities in inactive markets. The fair value of the Company’s outstanding borrowings under the Company’s revolving credit facility was based on level 2 inputs and fair value was determined using inputs other than quoted prices that are observable, specifically, discounted cash flows of expected payments at current borrowing rates. The Company’s carrying value approximates fair value for the Company’s long term debt and revolving credit facility.

Financial assets measured at fair value are summarized below (in thousands):


	Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs
	June 26, 2015				December 26, 2014
	(level 1)		(level 2)		(level 1)		(level 2)
Money market fund deposits (1)	$	3,794	$	—	$	14,396	$	—

(1)	Included in cash and cash equivalents on the condensed consolidated balance sheet. The carrying amounts approximate fair value due to the short-term maturities of the cash equivalents.

Inventories — Inventories are stated at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market. The Company evaluates the valuation of all inventories, including raw materials, work-in-process, finished goods and spare parts on a periodic basis. Obsolete inventory or inventory in excess of management’s estimated usage is written-down to its estimated market value less costs to sell, if less than its cost. Inherent in the estimates of market value are management’s estimates related to economic trends, future demand for products, and technological obsolescence of the Company’s products.

Inventory write downs inherently involve judgments as to assumptions about expected future demand and the impact of market conditions on those assumptions. Although the Company believes that the assumptions it used in estimating inventory write downs are reasonable, significant changes in any one of the assumptions in the future could produce a significantly different result. There can be no assurances that future events and changing market conditions will not result in significant increases in inventory write downs.

Equipment and Leasehold Improvements — Equipment and leasehold improvements are stated at cost, or, in the case of equipment under capital leases, the present value of future minimum lease payments at inception of the related lease. Depreciation and amortization are computed using the straight-line method over the lesser of the estimated useful lives of the assets or the terms of the leases. Useful lives range from three to fifteen years.

Product Warranty — The Company provides warranties on its products for a period of up to two years and provides for warranty costs at the time of sale based on historical activity. The determination of such provisions requires the Company to make estimates of product return rates and expected costs to repair or replace the products under warranty. If actual return rates and/or repair

- 8 -

and replacement costs differ significantly from these estimates, adjustments to cost of sales may be required in future periods. Components of the reserve for warranty costs consisted of the following (in thousands):


	Three months ended
	June 26, 2015			June 27, 2014
Beginning balance	$	109		$	101
Change in reserve		10			100
Warranty costs incurred in the current period		(35	)		(74	)

Ending balance	$	84		$	127

Income Taxes — The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible amounts in the future. In evaluating our ability to realize our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. In projecting future taxable income, we begin with historical results and incorporate assumptions about the amount of future state, federal, and foreign pretax operating income adjusted for items that do not have tax consequences. The assumptions about future taxable income require significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, we consider recent cumulative income (loss). A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized.

The Company continued to maintain a full valuation allowance on its California, Oregon, and one of its Chinese subsidiaries deferred tax amounts as of June 26, 2015 totaling $3.2 million. Income tax positions must meet a more likely than not recognition threshold to be recognized. Income tax positions that previously failed to meet the more likely than not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more likely than not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of income as income tax expense. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a material impact on its results of operations and financial position. Management believes that it has adequately provided for any adjustments that may result from these examinations; however, the outcome of tax audits cannot be predicted with certainty.

The determination of the Company’s tax provision is subject to judgments and estimates.

Revenue Recognition — Product revenue is generally recorded upon shipment. When arrangements specify title transfer upon delivery, revenue is not recognized until the product is delivered. The Company recognizes revenue when persuasive evidence of an arrangement exists, shipment has occurred, price is fixed or determinable and collectability is reasonably assured. If the Company has not substantially completed a product or fulfilled the terms of a sales agreement at the time of shipment, revenue recognition is deferred until fulfillment. The Company’s standard arrangement for its customers includes a signed purchase order or contract, no right of return of delivered products and no customer acceptance provisions. The Company assesses collectability based on the credit worthiness of the customer and past transaction history. The Company continually performs credit evaluations of its customers and, if necessary, may require collateral from its customers.

Research and Development Costs — Research and development costs are expensed as incurred.

Net Income per Share — Basic net income per share is computed by dividing net income by the weighted average number of shares outstanding for the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares outstanding and common equivalent shares from dilutive stock options and restricted stock using the treasury stock method, except when such shares are anti-dilutive (see Note 7 to condensed consolidated financial statements).

Comprehensive Income — The Company reports by major components and as a single total, the change in its net assets during the period from non-owner sources. Comprehensive income for all periods presented was the same as net income.

- 9 -

Segments — The Financial Accounting Standards Board’s (FASB) guidance regarding disclosure about segments in an enterprise and related information establishes standards for the reporting by public business enterprises of information about reportable segments, products and services, geographic areas, and major customers. The method for determining what information to report is based on the manner in which management organizes the reportable segments within the Company for making operational decisions and assessments of financial performance. The Company’s chief operating decision-maker is considered to be the Chief Executive Officer. The Company operates in one reporting segment.

Business Combinations — The Company recognizes assets acquired (including goodwill and identifiable intangible assets) and liabilities assumed at fair value on the acquisition date. Subsequent changes to the fair value of such assets acquired and liabilities assumed are recognized in earnings, after the expiration of the measurement period, a period not to exceed 12 months from the acquisition date. Acquisition-related expenses and acquisition-related restructuring costs are recognized in earnings in the period in which they are incurred.

Stock-Based Compensation Expense

The Company maintains stock-based compensation plans which allow for the issuance of equity-based awards to executives and certain employees. These equity-based awards include stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”) which can be either time-based or performance-based. The Company also maintains an employee stock purchase plan that provides for the issuance of shares to all eligible employees of the Company at a discounted price.

Stock-based compensation expense includes compensation costs related to estimated fair values of stock options and awards granted. The estimated fair value of the Company’s equity-based awards, net of expected forfeitures, is amortized over the awards’ vesting period on a straight-line basis over a weighted average period of four years for stock options, three years for RSUs and one year for RSAs, and will be adjusted for subsequent changes in estimated forfeitures related to all equity-based awards and performance as it relates to performance-based RSUs.

The Company applies the fair value recognition provisions based on the FASB’s guidance regarding stock-based compensation. The exercise price of each stock option equals the market price of the Company’s stock on the date of grant. Most options are scheduled to vest over four years and expire no later than ten years from the grant date. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The determination of the fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding certain variables. These variables include the expected term of the awards; the Company’s expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends. The Company estimates the expected term of share-based awards granted based on the Company’s historical option term experience. The Company estimates the volatility of its common stock based upon the Company’s historical stock price volatility over the length of the expected term of the options. The Company bases the risk-free interest rate that it uses in the option valuation model on U.S. Treasury zero-coupon issues with remaining maturities similar to the expected term of the options. The Company does not anticipate paying any cash dividends in the foreseeable future and therefore uses an expected dividend yield of zero in the option valuation model. The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and records share-based compensation expense only for those awards that are expected to vest. The Company also considers, each quarter, whether there have been any significant changes in facts and circumstances that would affect its estimated forfeiture rate.

Employee Stock Purchase Plan

The Company also maintains an employee stock purchase plan (“ESPP”) that provides for the issuance of shares to all eligible employees of the Company at a discounted price. Under the ESPP, substantially all employees may purchase the Company’s common stock through payroll deductions at a price equal to 95 percent of the fair market value of the Company’s stock at the end of each applicable purchase period.

Restricted Stock Units and Restricted Stock Awards

The Company grants RSUs to employees and RSAs to non-employee directors as part of the Company’s long term equity compensation plan.

Restricted Stock Units — RSUs are granted to employees with a per share or unit purchase price of zero dollars and either have time based or performance based vesting. RSUs typically vest over three years, subject to the employee’s continued service with the Company. For purposes of determining compensation expense related to these RSUs, the fair value is determined based on the closing market price of the Company’s common stock on the date of award. The expected cost of the grant is reflected over the service period, and is reduced for estimated forfeitures.

During the quarter ended March 27, 2015, the Company granted 456,500 RSU’s, with a weighted average fair value of $8.68 per share, and granted 90,500 performance stock units with a weighted average fair value of $8.35 per share. During the quarter ended June 26, 2015, the Company granted 134,000 RSU’s, with a weighted average fair value of $6.53 per share.

During the six months ended June 26, 2015, 39,938 vested shares were withheld to satisfy withholding tax obligations, resulting in the net issuance of 313,712 shares. As of June 26, 2015, approximately $ 7.0 million of stock-based compensation cost, net of estimated forfeitures, related to RSU’s remains to be amortized over a weighted average period of 2.3 years. As of June 26, 2015, a total of 1,169,306 RSU’s remain outstanding with an aggregate intrinsic value of $ 7.6 million and a weighted average remaining contractual term of 1.5 years.

Restricted Stock Awards — As of June 26, 2015, a total of 56,000 RSAs remain outstanding. The total unamortized expense of the Company’s unvested restricted stock awards as of June 26, 2015, was $ 0.3 million.

Recent Accounting Pronouncements

In April 2015, the FASB issued authoritative guidance that requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts. The authoritative guidance is effective for the Company in the first quarter of fiscal 2017 and should be applied retrospectively. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company’s consolidated financial statements.

3. Acquisitions

On February 5, 2015, the Company completed the acquisition of certain of the assets and liabilities of Marchi, a designer and manufacturer of specialty thermocouples, heaters and temperature controllers, for approximately $29.9 million in cash and 1,437,500 shares of newly issued common stock for a total purchase price of approximately $43.7 million. In addition, the Company incurred approximately $0.2 million of costs related to the acquisition. The Company completed this acquisition primarily in order to expand its capabilities with existing customers and to bring the Company closer to the customer in the design stage of new products and next generation equipment. The Company financed the cash portion of the acquisition by borrowing a total of $29.7 million under a new Credit Agreement. See further discussion of the new borrowing arrangements in Note 5 to the Notes to Condensed Consolidated Financial Statements.

The Company allocated the purchase price of Marchi to the tangible assets, liabilities and identifiable intangible assets acquired, based on their estimated fair values. The excess of purchase price over the aggregate fair value was recorded as goodwill. Goodwill associated with the acquisition is primarily attributable to the future technology, market presence and knowledgeable and experienced workforce. Although goodwill is not amortized for financial accounting purposes, it is amortized in its entirely for tax purposes over fifteen years. The fair value assigned to identifiable intangible assets acquired was determined using the income approach taking into account the Company’s consideration of a number of inputs, including an independent third party analysis that was based upon estimates and assumptions provided by the Company. These estimates and assumptions were determined through established and generally accepted valuation techniques. The estimated fair value of the tangible and intangible assets acquired was allocated at Marchi’s acquisition date. The primary areas of the preliminary purchase price allocation that are not yet finalized relate to the fair values of inventory, non-income based taxes and residual goodwill.

During the measurement period, which can be no more than one year from the date of acquisition, we expect to continue to obtain information to assist us in determining the final fair value of the net assets acquired at the acquisition date during the measurement period. The preliminary purchase price for the acquisition is allocated as follows:


Fair Market Values (in thousands)

Property and equipment, net		767
Goodwill		18,380
Purchased intangible assets		23,370
Other non-current assets		26

Customer relationships	10	$	9,900
Trade name	6		1,170
Intellectual properties/know-how	8 - 12		12,300

Total purchased intangible assets		$	23,370

Goodwill is not amortized but is reviewed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.

The results of operations for the Company for the first half of fiscal 2015 include five full months of operating activity for Marchi. For the three and six months ended June 26, 2015, net sales of approximately $4.1 million and $6.2 million, respectively and operating income of approximately $1.5 million and $2.2 million, respectively attributable to Marchi were included in the consolidated results of operations. For the three and six months ended June 26, 2015, results of operations included charges of $0.7 million and $1.1 million, respectively, attributable to amortization of purchased intangible assets and $0.2 million of deal costs associated with the acquisition. Deal costs are included in general and administrative expenses in the Company’s consolidated results of operations.

The following unaudited pro forma consolidated results of operations assume the acquisition was completed as of the beginning of the year of the reporting periods presented. The unaudited pro forma consolidated results of operations for the three and six months ended June 26, 2015 and June 27, 2014 (in thousands, except per share amounts) as follows:


	Three Months Ended				Six Months Ended
	June 26, 2015		June 27, 2014		June 26, 2015		June 27, 2014
Net sales	$	117,549	$	135,405	$	244,443	$	283,184

Diluted earnings per share	$	0.06	$	0.16	$	0.10	$	0.35

The unaudited pro forma results above include adjustments related to the purchase price allocation and financing of the acquisition, primarily to increase amortization for the identifiable intangible assets, to increase interest expense for the additional debt incurred to complete the acquisition, to reflect the related income tax effect and to adjust weighted shares issued as part of the acquisition. The unaudited pro forma results for the three and six months ended June 26, 2015 include acquisition related costs of $0.2 million which are not expected to occur in future quarters. The unaudited pro forma condensed combined financial information has been prepared by management for illustrative purposes only and are not necessarily indicative of the condensed consolidated financial position or results of income in future periods or the results that actually would have been realized had UCT and Marchi been a combined company during the specified periods. The unaudited pro forma condensed combined financial information does not reflect any operating efficiencies and/or cost savings that we may achieve with respect to the combined companies, or any liabilities that may result from integration activities.

4. Goodwill and Purchased Intangible Assets

The Company’s methodology for allocating the purchase price relating to acquisitions is determined through established and generally accepted valuation techniques. Goodwill is measured as the excess of the cost of the acquisition over the sum of the amounts assigned to tangible and identifiable intangible assets acquired less liabilities assumed. The Company assigns assets acquired (including goodwill) and liabilities assumed to one or more reporting units as of the date of acquisition. Typically, acquisitions relate to a single reporting unit and thus do not require the allocation of goodwill to multiple reporting units. If the products obtained in an acquisition are assigned to multiple reporting units, the goodwill is distributed to the respective reporting units as part of the purchase price allocation process. Goodwill and purchased intangible assets with indefinite useful lives are not amortized, but are reviewed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The Company regularly monitors current business conditions and other factors including, but not limited to, adverse industry or economic trends and lower projections of profitability that may impact future operating results.

To test goodwill for impairment, the Company first performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, the Company then performs the two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. Under the two-step goodwill impairment test, the Company would in the first step compare the estimated fair value of each reporting unit to its carrying value. The Company determines the fair value of each of its reporting units based on a weighting of income and market approaches. If the carrying value of a reporting unit exceeds its fair value, the Company would then perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. If the Company determines that the carrying value of a reporting unit’s goodwill exceeds its implied fair value, the Company would record an impairment charge equal to the difference.

The evaluation of goodwill and intangible assets for impairment requires the exercise of significant judgment. In the event of future changes in business conditions, the Company will be required to reassess and update its forecasts and estimates used in future impairment analyses. If the results of these future analyses are lower than current estimates, a material impairment charge may result at that time.

Purchased Intangible Assets

Intangible assets are generally recorded in connection with a business acquisition. The Company evaluates the useful lives of its intangible assets each reporting period to determine whether events and circumstances require revising the remaining period of amortization. In addition, the Company reviews indefinite lived intangible assets for impairment when events or changes in circumstances indicate their carrying value may not be recoverable and tests definite lives intangible assets at least annually for impairment. Management considers such indicators as significant differences in product demand from the estimates, changes in the competitive and economic environment, technological advances, and changes in cost structure.

In addition to the Marchi and AIT tradename intangible assets of $3.1 million, the Company is also carrying a UCT tradename intangible asset of $9.0 million as a result of a previous acquisition. The Company concluded that the UCT tradename intangible asset life is indefinite and is therefore not amortized but is reviewed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.

- 14 -

The Company amortizes its tradenames (AIT and Marchi) and customer relationships (AIT) intangible assets using an accelerated method over the estimated economic life of the assets, ranging from 6 to 7 years. The Company amortizes its intellectual property/know-how intangible and customer relationships (Marchi) asset on a straight-line basis with an estimated economic life of the assets ranging from 7 to 12 years. Amortization expense were approximately $1.4 million and $1.2 million for the three months ended June 26, 2015 and June 27, 2014, respectively and $ 2.5 million and $2.4 million for the six months ended June 26, 2015 and June 27, 2014, respectively. Amortization expense is charged to General and Administrative. As of June 26, 2015, future estimated amortization expense is expected to be as follows (in thousands):

5. Borrowing Arrangements

Prior to February 5, 2015, the Company had borrowing arrangements with Silicon Valley Bank under a Loan and Security Agreement (the “Loan Agreement”) which included a $40.0 million revolving credit facility (the “Revolver”), maturing on July 3, 2016, and a $40.0 million term loan (the “Term Loan”), maturing on July 3, 2016. The interest rate on the Revolver during the month of January 2015 was 3.75%.

On February 2, 2015, the Company entered into a new credit agreement (the “Credit Agreement”) by and among the Company, certain of its subsidiaries, East West Bank and Citi National Bank (collectively, the “Lenders”). The new credit agreement was amended in April 3, 2015 (as amended, the “Credit Agreement”) to modify certain term of the agreement. The Credit Agreement provides for a term loan in an aggregate principal amount of $40.0 million (the “New Term Loan”) and a revolving credit facility in an aggregate principal amount of $40.0 million (the “New Revolving Credit Facility”), a letter of credit facility in the aggregate availability amount of $20.0 million (as a sublimit of such New Revolving Credit Facility) (the “L/C Facility”) and a swingline sub-facility in the aggregate availability amount of $5.0 million (as a sublimit of the New Revolving Credit Facility) (together with the Term Loan, the Revolving Credit Facility and the L/C Facility, the “Senior Secured Credit Facility”). On February 2, 2015, the Company borrowed an aggregate of $40.0 million under the New Term Loan and approximately $6.5 million under the New Revolving Credit Facility. The borrowed funds were used to repay the outstanding balance to Silicon Valley Bank as lender under our prior Loan Agreement. The prior Loan Agreement was terminated in connection with this transaction and, as a result, the outstanding balance of the revolver of $31.3 million was classified as long-term debt as of December 26, 2014 in accordance with the terms of the new debt agreement. In addition, we expensed the unamortized debt issuance costs of approximately $0.7 million in the first quarter of 2015. On February 5, 2015, in order to finance the acquisition of Marchi, the Company borrowed $29.7 million under the New Revolving Credit Facility.

The New Term Loan must be repaid in consecutive quarterly installments of $1.25 million for the first four installments and $2.9 million for the remaining twelve installments, with the first payment made on March 31, 2015, and with the balance of the outstanding principal amount of the New Term Loan due at the final maturity, which is February 2, 2019. The New Revolving Credit Facility is available for the four-year period beginning on February 2, 2015. The Credit Agreement includes customary representations, warranties, covenants and events of default. The Company and certain of its subsidiaries have agreed to secure all of their obligations under the Credit Agreement by granting a first priority lien in substantially all of their respective personal property assets (subject to certain exceptions and limitations).

At the Company’s option, borrowings under the New Term Loan and New Revolving Credit Facility (subject to certain limitations) bear interest at either a base rate or at the London Interbank Offered Rate (“LIBOR”) (with the LIBOR being adjusted for certain Eurocurrency reserve requirements, if any, as described in the Credit Agreement), plus, in each case, an applicable margin based on the Company’s consolidated leverage ratio. All loans described above made on February 2, 2015 were initially base rate loans, carrying interest of 3.25%. The Company expects, however, that the effective interest rate will be higher due to the incurrence of certain loan-related costs of $0.6 million that have been treated as a discount on the debt and amortized over the life of the loan. As of June 26, 2015, the interest rates on the outstanding new Term Loan and new Revolving Credit facility were 2.69% and 3.00%, respectively.

- 15 -

The Credit Agreement requires the Company to maintain certain financial covenants including a consolidated fixed charge coverage ratio (as defined in the Credit Agreement) of at least 1.25 to 1.00 starting with the end of the first quarter of fiscal 2015 and a consolidated leverage ratio (as defined in the Credit Agreement) no greater than 3.5 to 1.00 starting with the end of the first quarter of fiscal 2015. The Credit Agreement also includes other customary affirmative and negative covenants. The Company was in compliance with all covenants for the quarter ended June 26, 2015.

The Credit Agreement also contains provisions requiring the following mandatory prepayments (subject to certain exceptions and limitations): annual prepayments in an amount equal to (a) 33% of excess cash flow (as defined in the Credit Agreement) if the aggregate outstanding principal amount of the New Term Loan equals or exceeds $20.0 million and (b) 25% of excess cash flow if the aggregate outstanding principal amount of the New Term Loan equals or exceeds $10.0 million but is less than $20.0 million. The Credit Agreement also restricts us from declaring or paying any cash dividends.

As of June 26, 2015, the outstanding amounts under the Company’s New Term Loan and New Revolving Credit Facility were $38.7 million and $36.2 million, respectively, which are gross of unamortized debt issuance costs of $0.5 million for a total debt balance of $74.4 million.

6. Income Tax

The Company’s income tax provision and effective tax rate for the three and six month periods ended June 26, 2015 were $0.9 million and 28.1% and $1.4 million and 29.0 %, respectively compared to $1.6 million and 20.7% and $3.1 million and 18.9%, respectively for the three and six month periods ended June 27, 2014. The change in respective rates reflects, primarily, changes in the geographic mix of worldwide earnings and financial results, as well as the impact of losses which have a full valuation allowance for the three and six month periods ended June 26, 2015 compared to the three and six month periods ended June 27, 2014. Our effective tax rates were lower than the statutory rates for the first and second quarters of fiscal years 2015 and 2014 primarily due to the geographic distribution of our world-wide earnings in foreign jurisdictions with lower tax rates or tax holidays, such as the tax holiday we are currently enjoying in Singapore.

Company management continuously evaluates the need for a valuation allowance and as of June 26, 2015, concluded that a full valuation allowance on its California, Oregon, and one of its Chinese subsidiaries was still appropriate.

The Company earns a significant amount of its operating income outside the United States, which is deemed to be indefinitely reinvested in foreign jurisdictions. As a result, most of the Company’s cash and cash equivalents are held by foreign subsidiaries. The Company currently does not intend nor foresee a need to repatriate these funds to the U.S. The Company expects existing domestic cash and cash flows from operations to continue to be sufficient to fund its domestic operating activities and cash commitments for investing and financing activities, such as debt repayment and capital expenditures, for at least the next 12 months and thereafter for the foreseeable future. If the Company should require more capital in the U.S. than is generated by its domestic operations, for example to fund significant discretionary activities such as business acquisitions, the Company could elect to repatriate future earnings from foreign jurisdictions or raise capital in the United States through debt or equity issuances. These alternatives could result in higher effective tax rates, increased interest expense, or dilution of our earnings. The Company has borrowed funds domestically and continues to believe it has the ability to do so at reasonable interest rates. The Company does not provide for U.S. taxes on its undistributed earnings of foreign subsidiaries that it intends to invest indefinitely outside the U.S., unless such taxes are otherwise required under U.S. tax law. In 2014, the Company determined that a portion of the current year earnings of one of its China subsidiaries may be remitted in the future to one of its foreign subsidiaries outside of mainland China and, accordingly, the Company provided for the related withholding taxes in its consolidated financial statements. If the Company changes its intent to reinvest its undistributed foreign earnings indefinitely or if a greater amount of undistributed earnings are needed than the previous anticipated remaining unremitted foreign earnings, the Company could be required to accrue or pay U.S. taxes on some or all of these undistributed earnings. As of June 26, 2015, the Company had undistributed earnings of foreign subsidiaries that are indefinitely invested outside of the U.S. of approximately $67.1 million. It is not practicable to determine the income tax liability that might be incurred if these earnings were to be distributed.

The following table summarizes the activity related to the Company’s unrecognized tax benefits (in thousands):


	Six months ended
	June 26, 2015			June 27, 2014
Balance as of the beginning of period	$	356		$	165
Increase (decrease) related to current year tax positions		(31	)		141

Balance as of the end of period	$	325		$	306

The Company’s gross liability for unrecognized tax benefits as of June 26, 2015 and December 26, 2014 was $0.3 million and $0.4 million, respectively. Increases or decreases to interest and penalties on uncertain tax positions are included in income tax provision in the condensed consolidated statements of operations. Interest related to uncertain tax positions was immaterial for each of the three and six month periods ended June 26, 2015 and June 27, 2014. Although it is possible some of the unrecognized tax benefits could be settled within the next twelve months, the Company cannot reasonably estimate the outcome at this time.

The determination of the Company’s tax provision is subject to judgments and estimates. The carrying value of the Company’s net deferred tax assets, which is made up primarily of tax deductions and net operating loss carryforwards, assumes the Company will be able to generate sufficient future income to fully realize the income tax benefit. In determining whether the realization of these deferred tax assets may be impaired, the Company makes judgments with respect to whether the Company is likely to generate sufficient future taxable income to realize these assets. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a material impact on the Company’s results of operations and financial position.

The Company files income tax returns in the U.S. federal jurisdiction, various states and foreign jurisdictions. The Company’s 2011 through 2013 federal income tax returns are open to audit through the statute of limitations by the Internal Revenue Service. The Company’s 2010 through 2013 state income tax returns are open to audit by the California Franchise Tax Board. The Company is also subject to examination in various other jurisdictions for various periods.

The Company is currently enjoying a zero rate tax holiday related to its Singapore subsidiary that will expire for tax years beginning January 2016. This tax rate is subject to achieving certain commitments agreed to with the Economic Development Board of Singapore including investment and employment thresholds. The Company’s Singapore subsidiary recorded a net profit of $2.4 million and $4.5 million for the three and six month periods ended June 26, 2015, respectively.

7. Net Income Per Share

Basic net income per share excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that would occur if outstanding securities or other contracts to issue common stock were exercised or converted into common stock.

The following is a reconciliation of the numerators and denominators used in computing basic and diluted net income per share (in thousands, except per share data):


	Three months ended				Six months ended

The Company had securities outstanding which could potentially dilute basic net income per share in the future, but the incremental shares from the assumed exercise of these securities were excluded in the computation of diluted net income per share, as their effect would have been anti-dilutive. Such outstanding securities consisted of 391,676 stock options and 387,437 stock options for the three and six month periods ended June 26, 2015, respectively, and 261,479 stock options and 274,858 stock options for the three and six month periods June 27, 2014, respectively.

8. Commitments and Contingencies

The Company had commitments to purchase inventory totaling approximately $45.4 million at June 26, 2015.

The Company leases properties domestically in Hayward, California; Austin, Texas, Pflugerville, Texas; Chandler, Arizona; and South San Francisco, California and internationally in China, Singapore and the Philippines. The Company leases certain of its facilities under non-cancelable leases, which expire on various dates through 2022.

As of June 26, 2015, future minimum payments under these operating leases were as follows (in thousands):


Fiscal Year
2015 (remaining in year)	$	3,095
2016		5,337
2017		4,712
2018		3,573
2019		2,737
Thereafter		7,770

Total minimum lease payments	$	27,224

From time to time, the Company is subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings and claims cannot be predicted with certainty, the Company has not had a history of outcomes to date that have been material to the statement of operations and does not believe that any of these proceedings or other claims will have a material adverse effect on its consolidated financial condition or results of operations.

9. Segment and Geographic Information

The Company operates in one reportable segment and is engaged in the development, manufacture and supply of critical subsystems for the semiconductor capital equipment, consumer, medical, energy, industrial, flat panel and research industries. Multiple operating segments were aggregated into one reportable segment as the nature of the Company’s products and production processes, as well as type of customers and distribution methods, is consistent among all of the Company’s products. The Company’s foreign operations are conducted primarily through its wholly-owned subsidiaries in China and Singapore. The Company’s principal markets include North America, Asia and, to a lesser degree, Europe. Sales by geographic area represent sales to unaffiliated customers.

All information on sales by geographic area is based upon the location to which the products were shipped. The following table sets forth revenue by geographic area (in thousands):


	Three months ended				Six months ended
	June 26, 2015		June 27, 2014		June 26, 2015		June 27, 2014
United States	$	79,961	$	94,221	$	169,430	$	200,026
China		5,288		18,885		17,250		36,426
Singapore		29,170		13,046		47,402		30,666
Other		3,130		6,525		8,785		9,783

	$	117,549	$	132,677	$	242,867	$	276,901

At June 26, 2015 and June 27, 2014, approximately $8.5 million and $4.0 million, respectively, of the Company’s net long-lived assets were located in Asia, and the remaining balances were located in the United States.

10. Subsequent Events

On July 31, 2015, the Company completed the acquisition of all of the assets and liabilities of Miconex S.R.O. (“Miconex”), a provider of manufacturing services in advanced precision milling and welding of plastics for the semiconductor industry located in the Czech Republic. The purchase price of approximately $22.8 million includes $15.0 million in cash, subject to certain post-closing adjustments, 500,000 shares of newly issued common stock and up to $4.0 million of potential cash “earn-out” payments payable over a two-year period, based on Miconex’s achievement of specified performance targets. In addition, the Company expects to incur approximately $0.4 million of costs related to the acquisition, which have been expensed as incurred. The Company financed the entire cash portion of the acquisition through its existing Asia operating cash. The Company’s primary reason for this acquisition is to expand its manufacturing capabilities with its existing customers. Due to the limited time since the acquisition date and limitations on access to Miconex’s information prior to the acquisition date, the initial accounting for the business combination is incomplete at this time. As a result, the Company is unable to provide amounts recognized as of the acquisition date for major classes of assets and liabilities acquired and the information required for indemnification of assets, contingencies, non-controlling interests and goodwill. Also, because the initial accounting for the transaction is incomplete, the Company is unable to provide the supplemental pro forma revenue and earnings of the combined entity.

Overview

We are a global leader in the design, engineering, and manufacture of production tools, modules and subsystems for the semiconductor capital equipment industry and industry segments with similar requirements including consumer, medical and flat panel display. We focus on providing specialized engineering and manufacturing solutions for these applications. We enable our customers to realize lower manufacturing costs and reduced design-to-delivery cycle times while maintaining high quality standards.

We provide our customers with complete solutions that utilize our expertise in design, scan, assembly, test and component characterization. Our customers value our highly flexible global manufacturing operations, our excellence in quality control and our scale and financial stability. Our global footprint helps us to drive down total manufacturing costs, reduce design-to-delivery cycle times and maintain high quality standards for our customers. We believe that these characteristics provide global solutions for our customers’ growing product demands. We ship the majority of our products to U.S. registered customers with locations both in and outside the U.S. In addition to U.S. manufacturing, we manufacture products in our Asian facilities to support local and U.S. based customers. We conduct our operating activities primarily through our wholly owned subsidiaries, Ultra Clean Technology Systems and Service, Inc., AIT LLC, Ultra Clean Technology (Shanghai) Co., Ltd., Ultra Clean Micro-Electronics Equipment (Shanghai) Co., Ltd., Ultra Clean Asia Pacific, Pte Ltd. (Singapore), and subsequent to February 4, 2015, Marchi. On February 5, 2015, we acquired certain assets of Marchi to expand our capabilities with our existing customers and bring us closer to the customer in the design stage of new products and next generation equipment. On July 31, 2015, the Company completed the acquisition of all of the assets and liabilities of Miconex s.r.o. (“Miconex”), a provider of manufacturing services in advanced precision milling and welding of plastics for the semiconductor industry located in the Czech Republic, for a total purchase price of approximately $22.8 million. See Note 10 to the Notes to Condensed Consolidated Financial Statements for further details of this acquisition.

In February 2015, we reached an agreement with Intuitive Surgical (ISI) on the insourcing of manufacturing for their next generation robot, the da Vinci Xi Patient Side Cart. We will continue to manufacture previous generation robots and also assist with machined components and spare parts for current and future ISI production. This was a mutual decision driven by ISI’s manufacturing needs at the time and our desire to adhere to our targeted gross margin profile. The impact of this change is a decrease in revenue of approximately $7.1 million and $11.0 million for the three month and six months ended June 26, 2015, when compared to the same periods of the previous year. Included in our revenue for the first half of fiscal 2015 is a payment of $1.0 million we received from ISI as compensation for this arrangement.

Financial Highlights

Sales for the three months ended June 26, 2015, was $117.5 million, a decrease of $15.1 million, or 11.4%, from the comparable quarter of 2014. Gross profit for the three months ended June 26, 2015 decreased $2.3 million to $18.8 million, or 16.0% of sales, from $21.2 million, or 15.9% of sales, for the three months ended June 27, 2014. Total operating expenses for the three months ended June 26, 2015, were $15.4 million, or 13.1% of sales, compared to $13.1 million, or 9.9% of sales, for the three months ended June 27, 2014. We had net income of $2.2 million for the three months ended June 26, 2015, compared to net income of $6.0 million for the three months ended June 27, 2014.

Sales for the six months ended June 26, 2015, were $242.9 million, a decrease of $34.0 million, or 12.3%, from the comparable period of 2014. Gross profit for the six months ended June 26, 2015 decreased $5.7 million to $38.7 million, or 16.0 % of sales, from

- 20 -

$44.5 million, or 16.1 % of sales, during the comparable period of 2014. Total operating expenses for the six months ended June 26, 2015, were $32.7 million, or 13.5 % of sales, compared to $27.2 million, or 9.8% of sales, for the six months ended June 27, 2014. We earned net income of $3.4 million for the six months ended June 26, 2015 as compared to $13.1 million for the six months ended June 27, 2014.

We had significant sales to two customers for the three and six months ended June 26, 2015, for which each customer accounted for 10% or more of total sales. For further discussion, see Note 1. Organization and Significant Accounting Policies - Significant Sales to Customers in Notes to Condensed Consolidated Financial Statements above.

Results of Operations

For the periods indicated, the following table sets forth certain costs and expenses and other income items as a percentage of sales. The table and subsequent discussion should be read in conjunction with our condensed consolidated financial statements and notes thereto included elsewhere in our quarterly report.

Sales

Sales for the three months ended June 26, 2015, was $117.5 million, a decrease of $15.1 million, or 11.4%, from $132.7 million in the comparable quarter of 2014. The decrease in sales for the three months ended June 26, 2015 when compared to the same period of 2014 reflects a decrease in non-semiconductor sales of $24.0 million and an increase in semiconductor sales of $8.9 million. The decrease in overall sales in the second quarter of 2015 compared to the second quarter of 2014 is due in part to the bankruptcy of GTAT in October of 2014 and to a decrease in the volume of products shipped to ISI in the second quarter of 2015 due to their decisions to insource the manufacturing of their products in the first quarter of 2015. On a geographic basis, sales in the U.S. decreased by $9.9 million to $79.2 million, or 67.4% of sales, for the three months ended June 26, 2015 as compared to $89.1 million, or 67.1% of sales for the same period of 2014. Foreign sales also decreased by $5.2 million to $38.4 million, or 32.6% of sales, for the three months ended June 26, 2015 as compared to $43.5 million, or 32.8% of sales, for the same period of 2014. We expect sales to be higher in the third quarter of fiscal 2015 as compared to the second quarter of fiscal 2015 due to increasing overall customer demand.

Sales for the six months ended June 26, 2015, were $242.9 million, a decrease of $34.0 million, or 12.3%, from $276.9 million in the comparable period of 2014. The decrease in sales for the six months ended June 26, 2015, which includes decreases of $1.2 million and $32.8 million in both semiconductor and non-semiconductor industries, respectively, was due to a decrease in the volume of products shipped, which is attributable in part to the GTAT bankruptcy and in part to ISI insourcing the manufacturing of its products in the first quarter of 2015. Sales in the US for the six months ended June 26, 2015 decreased by $31.8 million to $164.7 million while sales in Asia also decreased by $2.3 million to $78.2 million.

Gross Profit

Cost of goods sold consists primarily of purchased materials, labor and overhead, including depreciation related to certain capital assets associated with the design and manufacture of products sold. Gross profit for the three months ended June 26, 2015 decreased by $2.3 million to $18.8 million, or 16.0% of sales, from $21.2 million, or 15.9% of sales, for the three months ended June 27, 2014. Gross profit for the six months ended June 26, 2015, decreased by $5.7 million to $38.7 million, or 16.0% of sales, from

- 21 -

$44.5 million, or 16.1% of sales, for the six months ended June 27, 2014. The decreases in absolute dollars of gross profit when comparing the three and six month periods ended June 26, 2015 with the same periods in 2014 is primarily due to lower sales volume and a sales mix which included lower margin products. We expect gross profit to be consistent in the third quarter of 2015 compared to the second quarter of 2015.

Research and Development Expense

Research and development expense consists primarily of activities related to new component testing and evaluation, test equipment and fixture development, product design, and other product development activities. Research and development expense for the three months ended June 26, 2015, increased by $0.6 million, or 33.5 %, to $2.4 million, or 2.0% of sales, compared to $1.8 million, or 1.4% of sales in the comparable period in 2014. Research and development expense for the six months ended June 26, 2015 increased by $1.4 million, or 39.3 %, to $5.0 million, or 2.0% of sales, compared to $3.6 million, or 1.3% of sales in the comparable period in 2014. The increases in absolute dollars for research and development expenses when comparing the three and six month period ended June 26, 2015 with the comparable periods in 2014 was due primarily to the inclusion of Marchi’s research and development activities in the first quarter of 2015.

Sales and Marketing Expense

Sales and marketing expense consists primarily of salaries and commissions paid to our sales and service employees, salaries paid to our engineers who work with the sales and service employees to help determine the components and configuration requirements for new products and other costs related to the sales of our products. Sales and marketing expense for the three months ended June 26, 2015 increased by $0.2 million, or 8.2%, to $2.8 million, or 2.4% of sales, compared to $2.6 million, or 2.0% of sales, in the comparable period of 2014. Sales and marketing expenses for the six months ended June 26, 2015, increased by $0.4 million to $5.7 million, or 2.3% of sales, compared to $5.3 million, or 1.9% of sales in the comparable period of 2014. The increase in sales and marketing expense for the three and six month period ended June 26, 2015 compared to the same period in the prior year is primarily due to additional headcount and related payroll expense in 2015 related in part to the inclusion of Marchi in the first quarter for 2015.

General and Administrative Expense

Our general and administrative expense has historically consisted primarily of salaries and overhead associated with our administrative staff, professional fees and amortization of our intangible assets. General and administrative expense increased approximately $1.5 million, or 17.1 %, for the three months ended June 26, 2015, to $10.2 million, or 8.7% of sales, compared with $8.7 million, or 6.6% of sales, in the comparable period of 2014. General and administrative expense increased approximately $3.6 million, or 19.7%, for the six months ended June 26, 2015, to $22.0 million, or 9.1% of sales, compared with $18.4 million, or 6.7% of sales, in the comparable period of 2014. The increase in absolute dollars when comparing the three months ended June 26, 2015 with the comparable period in 2014 is primarily due to higher compensation spend as a result of higher headcount and due to higher amortization of finite-lived intangibles obtained in conjunction with the acquisition of Marchi. The increase in absolute dollars when comparing the six months ended June 26, 2015 with the comparable period in 2014 is primarily due to severance of $2.4 million paid to our former CEO in the first quarter of 2015, $0.2 million of costs related to the acquisition of Marchi, Marchi’s general and administrative expenses of $0.8 million, offset by a decrease of $0.9 million in share-based compensation expense due to the cancellation of the unvested restricted stock units of our former CEO upon his retirement on January 19, 2015.

Interest and Other Income (Expense), net

Interest and other income (expense), net, for the three and six months ended June 26, 2015, was $(0.4) million and $(1.3) million compared to $(0.5) million and $(1.1) million in the comparable period of 2014. The increase in net expense for the six month period ended June 26, 2015 compared to the same period in the prior year is primarily due to the write-off of $0.7 million in the first quarter of 2015 of unamortized debt issuance costs related to the previous credit facility offset by the increase in interest income due to the increase of the average cash balance during the period.

Income Tax Provision

Our tax expense and effective tax rate for the three months ended June 26, 2015 and June 27, 2014 were $0.9 million and 28.1%, and $1.6 million and 20.7%, respectively. Our tax expense and effective tax rate for the six months ended June 26, 2015 and June 27, 2014 was $1.4 million and 29.0 %, and $3.1 million and 18.9%, respectively. The change in respective rates reflects, primarily, changes in the geographic mix of worldwide earnings and financial results, as well as the impact of losses which have a full valuation allowance for the three and six month periods ended June 26, 2015 compared to the three and six month periods ended June 26, 2014.

- 22 -

Company management continuously evaluates the need for a valuation allowance on its deferred tax assets and as of June 26, 2015, concluded that a full valuation allowance on its California, Oregon, and one of its Chinese subsidiaries was still appropriate.

For the three and six months ended June 26, 2015, we determined that a portion of the current year earnings of one of our China subsidiaries will be remitted in the future to one of our foreign subsidiaries outside of mainland China and, accordingly, we provided for the related foreign withholding taxes in our condensed consolidated financial statements. Accordingly, no provision for U.S. taxes has been provided with respect to these unremitted earnings. If we change our intent to reinvest our undistributed foreign earnings indefinitely or if a greater amount of undistributed earnings are needed than the previously anticipated remaining unremitted foreign earnings, we could be required to accrue or pay U.S. taxes on some or all of these undistributed earnings.

Liquidity and Capital Resources

We have required capital principally to fund our acquisitions and working capital needs, satisfy our debt obligations, maintain our equipment and purchase new capital equipment. As of June 26, 2015, we had cash of $76.6 million compared to $79.0 million as of December 26, 2014. Our cash and cash equivalents, as well as cash generated from operations, was our principal source of liquidity as of June 26, 2015.

For the six months ended June 26, 2015, we generated cash from operating activities of $4.1 million compared to cash provided from operating activities of $7.6 million for the comparable period of 2014. Operating cash flows in the six months ended June 26, 2015, included $ 7.0 million of non-cash activity comprised of depreciation, amortization of intangibles, stock compensation expense and amortization of debt issuance costs. Cash generated from operating activities included decreases in accounts receivable and deferred income taxes of $4.3 million and $0.7 million, respectively and increases in accrued compensation and related benefits of $1.1 million offset by the increases in inventory, prepaids and other and other non-current assets of $6.5 million, $1.6 million and $0.1 million, respectively and decreases in accounts payable and income taxes payable of $3.8 million and $0.4 million, respectively. Our cash flows from operations in any given period are largely driven by the timing of sales, the collection of accounts receivable and the payment of accounts payable.

Net cash used in investing activities for the six months ended June 26, 2015 was approximately $33.5 million and consisted of cash paid in connection with the acquisition of Marchi of $29.7 million and capital expenditures of $3.8 million primarily attributable to the expansion of our Singapore facility.

Net cash provided in financing activities for the six months ended June 26, 2015 was $27.0 million compared to net cash provided of $2.6 million for the comparable period of 2014. For the six months ended June 26, 2015, our net cash provided in financing activities was due primarily to the cash proceeds from the new term and revolver loans obtained on February 2, 2015 of $76.2 million and proceeds from the issuance of common stock related to our employee stock plans of $2.3 million. These increases were offset primarily by the $48.8 million payoff on the previous credit facility, $1.3 million of loan payment under the new credit facility and payment of $0.6 million of debt issuance costs related to the new credit facility.

We anticipate that our existing cash balance and operating cash flow will be sufficient to service our indebtedness and meet our working capital requirements and technology development projects for at least the next twelve months. The adequacy of these resources to meet our liquidity needs beyond that period will depend on our growth, the state of the global economy, our ability to meet our financial covenants under our credit facility, the cyclical expansion or contraction of the semiconductor capital equipment industry and the other industries we serve. As of June 26, 2015, approximately $63.2 million of non-U.S. cash and cash equivalents held by foreign subsidiaries may be subject to U.S. taxes if repatriated for U.S. operations. Of this amount, we intend to permanently reinvest all of these funds outside of the U.S. and we do not plan to repatriate these funds. The Company used its Asia cash and cash equivalents to finance the cash portion of the acquisition of Miconex on July 31, 2015. In order to expand our business or acquire additional complementary businesses or technologies, we may need to raise additional funds through equity or debt financings. If required, additional financing may not be available on terms that are favorable to us, if at all. If we raise additional funds through the issuance of equity or convertible debt securities, our stockholders’ equity interest will be diluted and these securities might have rights, preferences and privileges senior to those of our current stockholders. We may also require the consent of our senior lenders to raise additional funds through equity or debt financings. No assurance can be given that additional financing will be available or that, if available, such financing can be obtained on terms favorable to our stockholders and us.

Borrowing Arrangements

On February 2, 2015, we entered into a new credit agreement (the “Credit Agreement”) by and among us, certain of our subsidiaries, East West Bank and Citi National Bank (collectively, the “Lenders”). The credit agreement was amended on April 3, 2015 to delete from the definition of a change of control certain specified changes in the composition of our board of directors or a material change in our management. A change of control, as defined in the credit agreement, is an event of default under the credit agreement. The Credit Agreement provides for a term loan in an aggregate principal amount of $40.0 million (the “New Term Loan”)

- 23 -

and a revolving credit facility in an aggregate principal amount of $40.0 million (the “New Revolving Credit Facility”), a letter of credit facility in the aggregate availability amount of $20.0 million (as a sublimit of such New Revolving Credit Facility) (the “L/C Facility”) and a swingline sub-facility in the aggregate availability amount of $5.0 million (as a sublimit of the New Revolving Credit Facility) (together with the Term Loan, the Revolving Credit Facility and the L/C Facility, the “Senior Secured Credit Facility”). On February 2, 2015, we borrowed an aggregate of $40.0 million under the New Term Loan and approximately $6.5 million under the New Revolving Credit Facility. The borrowed funds were used to repay the outstanding balance to Silicon Valley Bank as lender under our prior Loan Agreement. The prior Loan Agreement was terminated in connection with this transaction and, as a result, the outstanding balance of the revolver of $31.3 million was classified as long-term debt as of December 26, 2014 in accordance with the terms of the new debt agreement. In addition, we expensed the unamortized debt issuance costs of approximately $0.7 million in the first quarter of 2015. On February 5, 2015, in order to finance the acquisition of Marchi, we borrowed $29.7 million under the New Revolving Credit Facility.

The New Term Loan must be repaid in consecutive quarterly installments of $1.25 million for the first four installments and $2.9 million for the remaining twelve installments, with the first payment made on March 31, 2015, and with the balance of the outstanding principal amount of the New Term Loan due at the final maturity, which is February 2, 2019. The New Revolving Credit Facility is available for the four-year period beginning on February 2, 2015. The Credit Agreement includes customary representations, warranties, covenants and events of default. We and certain of our subsidiaries have agreed to secure all of their obligations under the Credit Agreement by granting a first priority lien in substantially all of our respective personal property assets (subject to certain exceptions and limitations).

At our option, borrowings under the New Term Loan and New Revolving Credit Facility (subject to certain limitations) bear interest at either a base rate or at the London Interbank Offered Rate (“LIBOR”) (with the LIBOR being adjusted for certain Eurocurrency reserve requirements, if any, as described in the Credit Agreement), plus, in each case, an applicable margin based on our consolidated leverage ratio. All loans described above made on February 2, 2015 and February 5, 2015 were initially base rate loans, carrying interest of 3.25%. As of June 26, 2015, the interest rates on the outstanding new Term Loan and new Revolving Credit facility were 2.69% and 3.00%, respectively. We expect, however, that the effective interest rate will be higher due to the incurrence of certain loan-related costs of $0.6 million that have been treated as debt discount and amortized over the life of the loan.

The Credit Agreement requires us to maintain certain financial covenants including a consolidated fixed charge coverage ratio (as defined in the Credit Agreement) of at least 1.25 to 1.00 starting with the end of the first quarter of fiscal 2015 and a consolidated leverage ratio (as defined in the Credit Agreement) no greater than 3.5 to 1.00 starting with the end of the first quarter of fiscal 2015. The Credit Agreement also includes other customary affirmative and negative covenants. The Company was in compliance with all covenants for the quarter ended June 26, 2015.

Capital Expenditures

Capital expenditures were $5.8 million in the six months ended June 26, 2015. The Company’s anticipated capital expenditures for the remainder of 2015 are anticipated to be financed through cash from operations.

Off-Balance Sheet Arrangements

During the periods presented, we did not have any relations with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Contractual Obligations

Other than operating leases for certain equipment and real estate and purchase order commitments primarily for inventory, we have no off-balance sheet transactions, unconditional purchase obligations or similar instruments and, other than the arrangements described under “Borrowing Arrangements” above, are not a guarantor of any other entities’ debt or other financial obligations. The

Critical Accounting Policies, Significant Judgments and Estimates

Our condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, which require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosure at the date of our consolidated financial statements. On an on-going basis, we evaluate our estimates and judgments, including those related to sales, inventories, goodwill and intangible assets, stock compensation and income taxes. We base our estimates and judgments on historical experience and on various other factors that we believe to be reasonable under the circumstances, the results of which form the basis of our judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. We consider certain accounting policies related to revenue recognition, inventory valuation, accounting for income taxes, business combinations, valuation of intangible assets and goodwill, and equity incentives to employees to be critical policies due to the estimates and judgments involved in each.

ITEM 3.

Quantitative and Qualitative Disclosures About Market Risk

We are exposed to financial market risks, including changes in currency exchange rates and interest rates.

Foreign Exchange Rates

Currently, a significant majority of our sales and arrangements with third-party suppliers provide for pricing and payment in US dollars, which are not subject to material exchange rate fluctuations. While increases in the value of the U.S. dollar relative to other currencies would make our products more expensive relative to competing products priced in such other currencies, which could negatively impact our ability to compete and conversely, decreases in the value of the U.S. dollar relative to other currencies could result in our foreign suppliers raising their prices in order to continue doing business with us, we do not expect foreign currency exchange rate fluctuations to have a material effect on our results of operations.

Chinese authorities recently relaxed controls of China’s currency, the Renminbi, and allowed the currency to strengthen against other world currencies, including the U.S. dollar. We continue to monitor any potential impact of the appreciation of the Renminbi on our operations in China as well as globally. Changes in the value of the Renminbi did not have a material impact on our results of operations for any period presented in this Form 10-Q.

Interest Rates

Our interest rate risk relates primarily to our debt which totals $74.4 million (net of debt issuance costs) as of June 26, 2015, and carries interest rates pegged to either the prime rate or LIBOR. An immediate increase in interest rates of 100 basis points would increase our interest expense by approximately $0.2 million per quarter. This would be partially offset by increased interest income on our invested cash. Conversely, an immediate decline of 100 basis points in interest rates would decrease our interest expense by approximately $0.2 million per quarter. This would be partially offset by decreased interest income on our invested cash.

ITEM 4.

Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (the “Exchange Act”), management, including our Chief Executive Officer and Chief Financial Officer, conducted an evaluation as of the end of the period covered by this report, of the effectiveness of our disclosure controls and procedures as defined in Exchange Act Rule 13a-15(e). Based upon our evaluation, we concluded that our disclosure controls and procedures were effective as of June 26, 2015.

As required by Rule 13a-15(d), management, including our Chief Executive Officer and Chief Financial Officer, also conducted an evaluation of our internal control over financial reporting to determine whether any changes occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on our evaluation, we concluded that there has been no change during the fiscal quarter covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Any system of controls, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system will be met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events.

PART II. OTHER INFORMATION

ITEM 1.

Legal Proceedings

From time to time, we are subject to various legal proceedings and claims, either asserted or unasserted, that arise in the ordinary course of business. Although the outcome of the various legal proceedings and claims cannot be predicted with certainty, we have not had a history of outcomes to date that have been material to our statement of operations and do not believe that any of these proceedings or other claims will have a material effect on our consolidated financial condition or results of operations.

ITEM 1A.

Risk Factors

The cyclical and highly volatile nature of the industries we serve could harm our operating results.

Our business and operating results depend in significant part upon capital expenditures by manufacturers in the semiconductor capital equipment, consumer, medical, energy, industrial, flat panel and research industries, which in turn depend upon the current and anticipated market demand for such products. Historically, the industries we serve (in particular the semiconductor industry) have been highly cyclical, with recurring periods of over-supply of products that have had a severe negative effect on the demand for capital equipment used to manufacture such products. We have experienced and anticipate that we will continue to experience significant fluctuations in customer orders for our products through such cycles. Slowdowns in the industries we serve have had, and future slowdowns may also have, a material adverse effect on our operating results. During periods of decreasing demand for our products, we must be able to appropriately align our cost structure with prevailing market conditions, effectively manage our supply chain and motivate and retain employees. During periods of increased demand, we must increase manufacturing capacity and inventory to meet customer demands, effectively manage our supply chain and attract, retain and motivate a sufficient number of employees. If the industries we serve experience downturns, or if we are not able to timely and appropriately adapt to the changes in our business environment, our results of operations will be harmed. Also, the cyclical and volatile nature of the industries we serve make future revenues, results of operations and net cash flows difficult to estimate.

We rely on a small number of original equipment manufacturing customers for a significant portion of our sales, and any adverse change in our relationships with these customers, including a decision by such customers to insource critical subsystems or to give market share to one of our competitors, would adversely affect our business, results of operation and financial condition. Our customers also exert a significant amount of negotiating leverage over us, which may require us to accept lower operating margins, increased liability risk or changes in our operations in order to retain or expand our market share with them.

A relatively small number of OEM customers have historically accounted for a significant portion of our sales, and we expect this trend to continue. As a group, two customers accounted for 78.3% of our sales for the six month period ended June 26, 2015 and three customers accounted for 76.0% and 81.0% of our sales for fiscal years 2014 and 2013, respectively, and we expect that our sales will continue to be concentrated among a small number of customers. In addition, our customer contracts generally do not require customers to purchase any particular volume of products in any particular time period. Accordingly, the success of our business depends on OEMs continuing to outsource the manufacturing of critical subsystems to us. Because of the small number of OEMs in the markets we serve, most of which are already our customers, it would be difficult to replace lost revenue resulting from the loss of, or the reduction, cancellation or delay in purchase orders by, any one of these customers, whether due to their decision to not continue to outsource all or a portion of their critical subsystems for their capital equipment, their giving market share to our competitors or for

- 26 -

other reasons, such as customer’s bankruptcy or insolvency or decreased demand for such customer’s products. We have in the past lost business from customers who have taken the manufacturing of our products in-house or given market share to our competitors. For example, in February 2015 UCT came to an agreement with ISI to transition to insourced manufacturing for their next generation robot. UCT will continue to manufacture previous ISI’s generation robots and also assist with machined components and spare parts for current and future ISI production. Further, since our customers generally own the designs and other intellectual property to the products we manufacture, we cannot prevent them from licensing such designs and other intellectual property to our competitors for the manufacture of such products. If we are unable to replace revenue from customers who determine to take subsystem assembly in-house or give market share to our competitors, such events could have a material adverse impact on our financial position and results of operation.

In addition, consolidation among our customers, or a decision by any one or more of our customers to outsource all or most manufacturing and assembly work to a single equipment manufacturer, may further concentrate our business in a limited number of customers and expose us to increased risks relating to dependence on an even smaller number of customers.

In addition, by virtue of our largest customers’ size and the significant portion of revenue that we derive from them, as well as the competitive landscape, our customers are able to exert significant influence and pricing pressure in the negotiation of our commercial agreements and individual purchase orders and on the conduct of our business with them. Our customers often require reduced prices or other pricing, quality or delivery commitments as a condition to their awarding of market share to us or the placement of orders with us in any given period, which may, among other things, result in reduced operating margins in order to maintain or expand our market share. Our customers’ negotiating leverage also can result in customer agreements or terms and conditions that may contain significant liability risk to us. For example, some of our customers insist that we provide them indemnification against certain liabilities in our agreements with them, including claims of losses by their customers caused by our products, which may be uncapped. In some cases, we have determined to self-insure against liability risk in our customer agreements, meaning that we may be directly responsible for high magnitude liability claims by our customers without recourse to insurance proceeds from third-party insurers. Our customers may also pressure us to make other concessions in order to preserve or expand our market share with them, which may harm our business. For example, one or more of our customers may require us to move the manufacturing of our products from lower-cost geographies or locations such as China to higher-cost geographies or locations that are closer to such customer’s facilities, such as Singapore, which could result in reduced margins and a sub-optimal cost structure. If we are unable to retain and expand our business with our customers on favorable terms, or at all, our business and operating results will be adversely affected, or we may be susceptible to increased liability risk which, if realized, may have a material adverse effect on our business, cash flows, results of operation and financial condition.

We have also had to qualify, and are required to maintain our qualified status, as a supplier for each of our customers. This is often a lengthy process that involves the inspection and approval by a customer of our engineering, documentation, manufacturing and quality control procedures before that customer will place volume orders. Our ability to lessen the adverse effect of any loss of, or reduction in sales to, an existing customer through the rapid addition of one or more new customers is limited because of these qualification requirements. Consequently, the risk that our business, operating results and financial condition would be adversely affected by the loss of or any reduction in orders by, any of our significant customers is increased. Moreover, if we lost our existing status as a qualified supplier to any of our customers, such customer could cancel its orders from us or otherwise terminate its relationship with us, which could have a material adverse effect on our results of operation, cash flows and financial condition.

We are exposed to risks associated with weakness in the global economy.

We rely to a significant extent on OEM customers, whose business, in turn, depends largely on consumer spending and capital expenditures by businesses. Continuing uncertainty regarding the global economy continue to pose challenges to our business. Economic uncertainty and related factors, including current unemployment levels, uncertainty in European debt markets, fiscal uncertainty in the U.S. economy, market volatility and the slow rate of recovery of many countries from recent recessions, exacerbate negative trends in business and consumer spending and may cause certain of our customers to push out, cancel, or refrain from placing orders for products or services, which may reduce sales and materially affect our results of operation and financial condition. Difficulties in obtaining capital, uncertain market conditions, or reduced profitability may also cause some customers to scale back operations, exit businesses, merge with other manufacturers, or file for bankruptcy protection and potentially cease operations, leading to customers’ reduced research and development funding and/or capital expenditures and, in turn, lower orders from our customers and/or additional slow moving or obsolete inventory or bad debt expense for us. These conditions may also similarly affect key suppliers, which could impair their ability to deliver parts and result in delays for our products or require us to either procure products from high-cost suppliers, or if no additional suppliers exist, to reconfigure the design and manufacture of our products, and we may be unable to fulfill some customer orders. For example, on October 6, 2014, one of our new customers GT Advanced Technologies (GTAT), filed for bankruptcy under chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for the District of New Hampshire which impaired the collectability of our outstanding accounts receivable as well as the value of our on-hand inventory related to GTAT and also resulted in a charge for non-cancelable vendor commitments.

- 27 -

We have significant existing indebtedness; the restrictive covenants under our credit agreement or other limitations on financing may limit our ability to expand or pursue our business strategy or make capital expenditures; if we are forced to pay some or all of our indebtedness prior to its maturity, our financial position could be severely and adversely affected.

On February 2, 2015, we entered into a new credit agreement by and among us, certain of our subsidiaries, East West Bank and Citi National Bank. This credit agreement provides for a term loan in an aggregate principal amount of $40.0 million and a revolving credit facility in an aggregate principal amount of $40.0 million, a letter of credit facility in the aggregate availability amount of $20.0 million and a swingline sub-facility in the aggregate availability amount of $5.0 million. On February 2, 2015, we borrowed an aggregate of $46.5 million under this new credit agreement from East West Bank and Citi National Bank to repay the remaining outstanding balance from the loan obtained from Silicon Valley Bank, U.S. Bank National Association and HSBC Bank. On February 5, 2015, we borrowed an additional $29.7 million under this new credit agreement from East West Bank and Citi National Bank to finance the acquisition of Marchi. As of June 26, 2015, the long-term portion of our outstanding indebtedness, net of debt issuance costs, under our new credit facility was $67.9 million, and the short-term portion was $6.5 million.

Our new credit agreement contains certain covenants that restrict our ability to take certain actions, including our ability to:

•

incur additional debt, including guarantees, or create liens;

•

pay dividends and make distributions in respect of our capital stock;

•

repurchase capital stock;

•

make investments or other restricted payments;

•

engage in transactions with stockholders and affiliates;

•

sell or otherwise dispose of assets;

•

make payments on subordinated indebtedness; and

•

engage in certain mergers and acquisitions, new lines of business or make other fundamental changes.

The restrictive covenants in our credit agreement may therefore limit our strategic and financing options and our ability to return capital to our stockholders through dividends or stock buybacks.

Our new credit agreement also requires us to maintain certain financial and other covenants. We cannot assure you that we will be able to maintain compliance with such financial or other covenants. Our failure to comply with these covenants could result in an event of default which, if not cured or waived, could result in the acceleration of all of our indebtedness, which would materially adversely affect our financial health if we are unable to access sufficient funds to repay all the outstanding amounts. Moreover, if we are unable to meet our debt obligations as they come due, we could be forced to restructure or refinance such obligations, seek additional equity financing or sell assets, which we may not be able to do on satisfactory terms, or at all.

In addition, the credit agreement has certain mandatory prepayment provisions, including annual prepayments of excess cash flow above certain thresholds. As long as our indebtedness remains outstanding, the restrictive covenants and mandatory prepayment provisions could impair our ability to expand or pursue our business strategies or obtain additional funding.

Our dependence on our suppliers may prevent us from delivering an acceptable product on a timely basis.

We rely on both single-source and sole-source suppliers, some of whom are relatively small, for many of the components we use in our products. In addition, our customers often specify components of particular suppliers that we must incorporate into our products. Our suppliers are under no obligation to provide us with components. As a result, the loss of or failure to perform by any of these suppliers could adversely affect our business and operating results. In addition, the manufacturing of certain components and subsystems is a complex process. Therefore, if a supplier were unable to provide the volume of components we require on a timely basis and at acceptable prices and quality, we would have to identify and qualify replacements from alternative sources. However, the process of qualifying new suppliers for complex components is also lengthy and could delay our production, which would adversely affect our business, operating results and financial condition.

We may also experience difficulty in obtaining sufficient supplies of components and raw materials in times of significant growth in our business. For example, we have in the past experienced shortages in supplies of various components, such as mass flow controllers, valves and regulators, and certain prefabricated parts, such as sheet metal enclosures, used in the manufacture of our products. In addition, one of our competitors manufactures mass flow controllers that may be specified by one or more of our customers. If we are unable to obtain these particular mass flow controllers from our competitor or convince a customer to select alternative mass flow controllers, we may be unable to meet that customer’s requirements, which could result in a loss of market share.

- 28 -

If we, or our suppliers, are unable to procure sufficient quantities of components or raw materials from suppliers, it could influence decisions by our customers to delay or cancel orders and decisions by our vendors to fulfill our purchase orders and, consequently, have a material adverse effect on our results of operations.

We may not be able to respond quickly enough to changes in demand for our products.

Demand shifts in the industries we serve are rapid and difficult to predict, and we may not be able to anticipate or respond quickly enough to changes in demand. Our ability to increase sales of our products in periods of increasing demand depends, in part, upon our ability to:

•

mobilize our supply chain in order to maintain component and raw material supply;

•

optimize the use of our design, engineering and manufacturing capacity in a timely manner;

•

deliver our products to our customers in a timely fashion;

•

expand, if necessary, our manufacturing capacity; and

•

maintain our product quality as we increase production.

If we are unable to respond to rapid increases in demand for our products on a timely basis or to manage any corresponding expansion of our manufacturing capacity effectively, our customers could increase their purchases from our competitors, which would adversely affect our business.

Our ability to remain profitable and mitigate the impact on our business in periods of decreasing demand depends, in part, upon our ability to:

•

optimize our inventory levels and reduce or cancel orders to our suppliers without compromising our relationships with such suppliers;

•

reduce our variable costs through a reduction of our manufacturing workforce;

•

continue to motivate our employees; and

•

maintain the prices, quality and delivery cycles of our products in order to retain our customers’ business.

We may not be able to fund our future capital requirements or strategic acquisitions from our operations, and financing from other sources may not be available on favorable terms or at all.

We made capital expenditures of approximately $5.8 million and $1.4 million for the six months period ended June 26, 2015 and June 27, 2014, respectively related to our manufacturing facilities in the United States, China and Singapore. In February 2015, we paid approximately $29.9 million and issued 1,437,500 shares of our common stock in connection with our acquisition of Marchi. The cash portion of the merger consideration was financed through the new credit facility described above; of which an aggregate of $74.9 million was outstanding as of June 26, 2015. The amount of our future capital requirements or strategic acquisitions will depend on many factors, including:

•

the cost required to ensure access to adequate manufacturing capacity;

•

the timing and extent of spending to support product development efforts;

•

the timing of introductions of new products and enhancements to existing products;

•

the cost required to complete AIT and Marchi’s enterprise resource planning implementation and to migrate AIT and its subsidiaries and Marchi to our enterprise resource planning system;

•

changing manufacturing capabilities to meet new customer requirements;

•

market acceptance of our products; and

•

our ability to identify appropriate acquisition opportunities and successfully negotiate the terms of such acquisitions.

We had $76.6 million in cash and cash equivalents as of June 26, 2015 of which $63.2 million was held by our foreign subsidiaries. If the cash and cash equivalents held by our foreign subsidiaries is needed for our operations or to fund capital expenditures or other strategic acquisitions in the U.S., we would be required to accrue and pay U.S. taxes to repatriate these funds.

Given our significant existing leverage, limited availability under our new revolving line of credit and the potential tax effects of repatriating foreign cash or other factors, we may need to raise additional funds through public or private equity or debt financing if

- 29 -

our current domestic cash and cash flow from operations are insufficient to fund our future activities. We may not be able to obtain additional debt financing when and if necessary in a timely manner. Access to capital markets has, in the past, been unavailable to companies such as ours and there can be no assurance that we would be able to complete an equity or other financing arrangement with terms satisfactory to us or at all. In addition, equity financings could be dilutive to holders of our common stock, and debt financings would likely involve additional covenants that restrict our business operations. Any potential strategic acquisition or significant capital expenditure may also require the consent of our existing lenders. If we cannot raise funds on acceptable terms, if and when needed, we may not be able to develop or enhance our products, take advantage of future opportunities, including potential acquisitions, grow our business or respond to competitive pressures or unanticipated requirements, any of which could adversely affect our business, operating results and financial condition.

Our quarterly revenue and operating results fluctuate significantly from period to period, and this may cause volatility in our common stock price.

Our quarterly revenue and operating results, including our gross margin, have fluctuated significantly in the past, and we expect them to continue to fluctuate in the future for a variety of reasons which may include:

•

demand for and market acceptance of our products as a result of the cyclical nature of the industries we serve or otherwise, often resulting in reduced sales during industry downturns and increased sales during periods of industry recovery or growth;

•

overall economic conditions;

•

changes in the timing and size of orders by our customers;

•

loss of business from one or more significant customers due to strategic decisions by our customers to terminate their outsourcing relationship with us or give market share to our competitors, or due to decreased demand for our customers’ products by end customers;

•

strategic consolidation by our customers;

•

cancellations and postponements of previously placed orders;

•

pricing pressure from either our competitors or our customers, resulting in the reduction of our product prices, margins or loss of market share;

•

disruptions or delays in the manufacturing of our products or in the supply of components or raw materials that are incorporated into or used to manufacture our products, thereby causing us to delay the shipment of products;

•

decreased margins for several or more quarters following the introduction of new products, especially as we introduce new subsystems;

•

delays in ramp-up in production, low yields or other problems experienced at our manufacturing facilities in China;

•

changes in design-to-delivery cycle times;

•

inability to reduce our costs quickly in step with reductions in our prices or in response to decreased demand for our products;

•

changes in our mix of products sold;

•

write-offs of excess or obsolete inventory due to a customer’s bankruptcy or insolvency;

•

one-time expenses or charges associated with failed acquisition negotiations or completed acquisitions;

•

inability to control our operating costs consistent with target levels;

•

announcements by our competitors of new products, services or technological innovations, which may, among other things, render our products less competitive; and

•

geographic mix of customer orders or worldwide earnings.

As a result of the foregoing, we believe that quarter-to-quarter comparisons of our revenue and operating results may not be meaningful and that these comparisons may not be an accurate indicator of our future performance. Changes in the timing or terms of a small number of transactions could disproportionately affect our operating results in any particular quarter. Moreover, our operating results in one or more future quarters may fail to meet our guidance or the expectations of securities analysts or investors. If this occurs, we would expect to experience an immediate and significant decline in the trading price of our common stock.

- 30 -

We have established, and as markets will allow, intend to expand our operations in Asia, which exposes us to risks associated with operating in a foreign country.

We generated approximately 32.2 % and 29.0% of our sales in international markets for the six months period ended June 26, 2015 and June 27, 2014, respectively. Depending on market conditions, we intend to expand our operations in Asia, principally in China and Singapore. In addition, through our acquisition of AIT, we acquired a manufacturing facility in Cebu, Philippines. The carrying amount of our fixed assets in Asia was $8.5 million as of June 26, 2015.

We are exposed to political, economic, legal and other risks associated with operating in Asia, including:

•

foreign currency exchange fluctuations;

•

political, civil and economic instability;

•

tariffs and other barriers;

•

timing and availability of export licenses;

•

disruptions to our and our customers’ operations due to increased risk of outbreak of diseases, such as SARS and avian flu;

•

disruptions in operations due to China’s developing domestic infrastructure, including transportation and energy;

•

difficulties in developing relationships with local suppliers;

•

difficulties in attracting new international customers;

•

difficulties in accounts receivable collections;

•

difficulties in staffing and managing distant international subsidiary and branch operations;

•

the burden of complying with foreign and international laws and treaties;

•

legal systems potentially subject to undue influence or corruption;

•

difficulties in transferring funds to other geographic locations; and

•

potentially adverse tax consequences, including restrictions on the repatriation of earnings to the United States.

In addition, due to generally lower labor and materials costs in the Asian markets in which we currently operate, a shift in the mix of orders from our customers away from such Asian markets could adversely affect our operating margins.

Our operations in Asia also subject us to U.S. laws governing the export of equipment. These laws are complex and require us to obtain clearances for the export to Asia of certain equipment. We may fail to comply with these laws and regulations, which could require us to cease the export of certain equipment and expose us to fines or penalties.

Over the past several years, the Chinese government has pursued economic reform policies, including the encouragement of private economic activity and greater economic decentralization. The Chinese government may not continue these policies or may significantly alter them to our detriment from time to time without notice. Changes in laws and regulations or their interpretation, the imposition of confiscatory taxation policies, new restrictions on currency conversion or limitations on sources of supply could materially and adversely affect our Chinese operations, which could result in the partial or total loss of our investment in that country and materially and adversely affect our future operating results.

We are subject to order and shipment uncertainties and any significant reductions, cancellations or delays in customer orders could cause our revenue to decline and our operating results to suffer.

Our revenue is difficult to forecast because we generally do not have a material backlog of unfilled orders and because of the short time frame within which we are often required to design, produce and deliver products to our customers. Most of our revenue in any quarter depends on customer orders for our products that we receive and fulfill in the same quarter. We do not have long-term purchase orders or contracts that contain minimum purchase commitments from our customers. Instead, we receive non-binding forecasts of the future volume of orders from our customers. Occasionally, we order and build component inventory in advance of the receipt of actual customer orders. Customers may cancel order forecasts, change production quantities from forecasted volumes or delay production for reasons beyond our control. Furthermore, reductions, cancellations or delays in customer order forecasts, which may occur for various reasons, including reduced demand for our customer’s products, customer bankruptcies or customer insolvency, usually occur without penalty to, or compensation from, the customer. Reductions, cancellations or delays in forecasted orders could cause us to hold inventory longer than anticipated, which could reduce our gross profit, restrict our ability to fund our operations and cause us to incur unanticipated reductions or delays in revenue. Moreover, most of the products we manufacture are custom built for our customers and are therefore not fungible with products we sell to other customers. If we do not obtain orders as we anticipate, we

- 31 -

could have excess component inventory for a specific product that we would not be able to sell to another customer, likely resulting in inventory write-offs, which could have a material adverse effect on our business, financial condition and operating results. In addition, because many of our costs are fixed in the short term, we could experience deterioration in our gross profit and operating margins when our production volumes decline.

The manufacturing of our products is highly complex, and if we are not able to manage our manufacturing and procurement process effectively, our business and operating results will suffer.

The manufacturing of our products is a highly complex process that involves the integration of multiple components and requires effective management of our supply chain while meeting our customers’ design-to-delivery cycle time requirements. Through the course of the manufacturing process, our customers may modify design and system configurations in response to changes in their own customers’ requirements. In order to rapidly respond to these modifications and deliver our products to our customers in a timely manner, we must effectively manage our manufacturing and procurement process. If we fail to manage this process effectively, we risk losing customers and damaging our reputation. We may also be subject to liability under our agreements with our customers if we or our suppliers fail to re-configure manufacturing processes or components in response to these modifications, which may lead to product defect claims by our customers. In addition, if we acquire inventory in excess of demand or that does not meet customer specifications, we could incur excess or obsolete inventory charges. These risks are even greater during the current extended period of macroeconomic uncertainty, and as we continue to expand our business beyond gas delivery systems into new subsystems. Certain of our suppliers may go out of business, which could require us to either procure products from higher-cost suppliers or, if no additional suppliers exist, reconfigure the design and manufacture of our products. This could limit our growth and have a material adverse effect on our business, financial condition and operating results.

If our new products are not accepted by OEMs or other customers or if we are unable to obtain historical margins on our new products, our operating results would be adversely impacted.

We design, develop and market critical systems and subsystems to OEMs and other customers. The introduction of new products is inherently risky because it is difficult to foresee the adoption of new standards, coordinate our technical personnel and strategic relationships and win acceptance of new products by OEMs and other customers. We may not be able to recoup design and development expenditures if our new products are not accepted by OEMs or other customers. Newly introduced products typically carry lower gross margins than existing products for several or more quarters following their introduction. If any of our new systems or subsystems are not successful in the market, or if we are unable to obtain gross margins on new products that are similar to the gross margins we have historically achieved, our business, operating results and financial condition could be adversely affected.

Interruption or failure of our information technology and communications systems could impair our ability to effectively deliver our products, which could cause us to lose customers and harm our results of operations.

The manufacture and delivery of our products depends on the continuing operation of our technology infrastructure and systems, particularly our data center located in California. Any damage to or failure of our systems could result in interruptions in our ability to manufacture or deliver products on agreed upon lead times, or at all, on a local or worldwide basis. Interruptions could reduce our sales and profits, and our reputation could be damaged if people believe our systems are unreliable. Our systems and operations are vulnerable to damage or interruption from earthquakes, terrorist attacks, floods, fires, power loss, hacking, hardware or software failures, telecommunications failures, computer viruses or other attempts to harm our systems, and similar events. The critical components of the system are not redundant and we currently do not have a backup data center. Accordingly, the risk associated with earthquakes, fire, power loss, telecommunications failure, and other events beyond our control is heightened.

Any unscheduled interruption in our manufacturing or deliveries would result in an immediate loss of sales and could have a material adverse effect on our results of operation and financial position. If we experience frequent or persistent system failures, the attractiveness of our products to customers could be permanently harmed. Any steps we take to increase the reliability and redundancy of our systems may be expensive, reduce our operating margin and may not be successful in reducing the frequency or duration of unscheduled interruptions.

Acquisitions could result in operating and integration difficulties, dilution, margin deterioration and other consequences that may adversely impact our business and results of operations.

We have made, and may in the future make, acquisitions of, or significant investments in, businesses that offer complementary products, services, technologies or market access. We expect that management will evaluate potential strategic transactions regularly with its advisors and our board of directors in the ordinary course of business. We may not be successful in negotiating the terms of potential acquisitions or financing potential acquisitions, and our due diligence may fail to identify all of the problems, liabilities or other challenges associated with an acquired business, product or technology, including issues related to intellectual property, product

- 32 -

quality or product architecture, regulatory compliance practices, revenue recognition or other accounting practices or employee or customer retention issues. In addition, we may not be successful in effectively integrating the acquired business, product or technology into our existing business and operations. The areas where we face risks include:

•

Management of the larger, more complex, combined business, including integrating supply and distribution channels, computer and accounting systems, and other aspects of operations;

•

Deterioration of gross margins due to the acquisition of the same customer base resulting in reduced pricing leverage;

•

Integration of the capabilities of the acquired businesses while maintaining focus on providing consistently high quality products;

•

Incorporation of different financial and reporting controls, processes, systems and technologies into our existing business environment;

•

Unknown liabilities and unforeseen expenses, delays or regulatory conditions associated with the acquisitions for which we do not have recourse under their respective agreements;

•

Performance shortfalls as a result of the diversion of management’s attention from the company’s operations;

•

Cultural challenges associated with integrating employees from the acquired business into our organization, and retention of employees from the businesses we acquire;

•

Retention of customers and partners of acquired business; and/or

•

Difficulties associated with the transition of customers into our existing business.

Our failure to address these risks or other problems encountered in connection with our past or future acquisitions and investments could cause us to fail to realize the anticipated benefits of such acquisitions or investments, incur unanticipated liabilities and substantial costs, and materially harm our business generally.

Our acquisitions could also result in dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities, or amortization expenses, impairment charges and restructuring charges, any of which could harm our financial condition or results. Also, the anticipated benefits or value of our acquisitions or investments may not materialize. Even if an acquisition or other investment is not completed, we may incur significant management time and effort and financial cost in evaluating such acquisition or investment, which could have an adverse effect on our results of operations. Furthermore, due to limited liquidity in the credit market and our existing leverage, the financing of any such acquisition may be difficult to obtain, and the terms of such financing may not be favorable.

If we were required to write down all or part of our goodwill and other intangible assets, our net income and net worth could be materially adversely affected.

We had $112.0 million of goodwill and other intangible assets recorded on our consolidated balance sheet as of June 26, 2015. Goodwill represents the excess of cost over the fair market value of net tangible and finite lived, identifiable intangible assets acquired in business combinations. If our market capitalization drops significantly below the amount of net equity recorded on our balance sheet, it could indicate a decline in our value and would require us to further evaluate whether our goodwill has been impaired. During the fourth quarter of each year, we perform an annual review of our goodwill to determine if it has become impaired, in which case we would write down the impaired portion of our goodwill. We also evaluate goodwill for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If we were required to write down all or a significant part of our goodwill, our financial results and net worth could be materially adversely affected.

Our business is largely dependent on the know-how of our employees, and we generally do not have an intellectual property position that is protected by patents.

Our business is largely dependent upon our design, engineering, manufacturing and testing know-how. We rely on a combination of trade secrets and contractual confidentiality provisions and, to a much lesser extent, patents, copyrights and trademarks to protect our proprietary rights. Accordingly, our intellectual property position is more vulnerable than it would be if it were protected primarily by patents. If we fail to protect our proprietary rights successfully, our competitive position could suffer, which could harm our operating results. We may be required to spend significant resources to monitor and protect our proprietary rights, and, in the event infringement or breach of our proprietary rights occurs, our competitive position in the market may be harmed. In addition, competitors may design around our technology or develop competing technologies and know-how. Further, since our customers generally own the designs and other intellectual property to the products we manufacture, we cannot prevent them from licensing such designs and other intellectual property to our competitors for the manufacture of such products.

- 33 -

Third parties have claimed and may in the future claim we are infringing their intellectual property, which could subject us to litigation or licensing expenses, and we may be prevented from selling our products if any such claims prove successful.

We have in the past and may in the future receive claims that our products, processes or technologies infringe the patents or other proprietary rights of third parties. In addition, we may be unaware of intellectual property rights of others that may be applicable to our products. Any litigation regarding our patents or other intellectual property could be costly and time-consuming and divert our management and key personnel from our business operations, any of which could have a material adverse effect on our business and results of operations. The complexity of the technology involved in our products and the uncertainty of intellectual property litigation increase these risks. Claims of intellectual property infringement may also require us to enter into costly license agreements. However, we may not be able to obtain licenses on terms acceptable to us, or at all. We also may be subject to significant damages or injunctions against the development, manufacture and sale of certain of our products if any such claims prove successful. We also rely on design specifications and other intellectual property of our customers in the manufacture of products for such customers. While our customer agreements generally provide for indemnification of us by our customers if we are subjected to litigation for third-party claims of infringement of such customer intellectual property, such indemnification provisions may not be sufficient to fully protect us from such claims, or our customers may breach such indemnification obligations to us, which could result in costly litigation to defend against such claims or enforce our contractual rights to such indemnification.

If we do not keep pace with developments in the industries we serve and with technological innovation generally, our products may not be competitive.

Rapid technological innovation in the markets we serve requires us to anticipate and respond quickly to evolving customer requirements and could render our current product offerings and technology obsolete. Technological innovations are inherently complex. We must devote resources to technology development in order to keep pace with such rapidly evolving technologies. We believe that our future success will depend upon our ability to design, engineer and manufacture products that meet the changing needs of our customers. This requires that we successfully anticipate and respond to technological changes in design, engineering and manufacturing processes in a cost-effective and timely manner. If we are unable to integrate new technical specifications into competitive product designs, develop the technical capabilities necessary to manufacture new products or make necessary modifications or enhancements to existing products, our business prospects could be harmed.

The timely development of new or enhanced products is a complex and uncertain process which requires that we:

•

design innovative and performance-enhancing features that differentiate our products from those of our competitors;

•

identify emerging technological trends in the industries we serve, including new standards for our products;

•

accurately identify and design new products to meet market needs;

•

collaborate with OEMs to design and develop products on a timely and cost-effective basis;

•

ramp-up production of new products, especially new subsystems, in a timely manner and with acceptable yields at acceptable costs;

•

successfully manage development production cycles; and

•

respond effectively to technological changes or product announcements by others.

If we are unsuccessful in keeping pace with technological developments for the reasons above or other reasons, our business prospects, results of operations and financial condition could be materially and adversely affected.

The industries in which we participate are highly competitive and rapidly evolving, and if we are unable to compete effectively, our operating results will be harmed.

We face intense competition from subsystem and component manufacturers in the industries we serve. Increased competition has in the past resulted, and could in the future result, in price reductions, reduced gross margins or loss of market share, any of which would harm our operating results. We are subject to significant pricing pressure as we attempt to maintain and increase market share with our existing customers. Competitors may offer reduced prices or introduce new products for the markets currently served by our products. These products may have better performance, lower prices and achieve broader market acceptance than our products. Further, OEMs typically own the design rights to their products and may provide these designs to other subsystem manufacturers. If our competitors obtain proprietary rights to these designs such that we are unable to obtain the designs necessary to manufacture products for our OEM customers, our business, financial condition and operating results could be adversely affected.

Our competitors may have greater financial, technical, manufacturing and marketing resources than we do. As a result, they may be able to respond more quickly to new or emerging technologies and changes in customer requirements, devote greater resources to

- 34 -

the development, promotion, sale and support of their products, and reduce prices to increase market share. Moreover, there may be merger and acquisition activity among our competitors and potential competitors that may provide our competitors and potential competitors an advantage over us by enabling them to expand their product offerings and service capabilities to meet a broader range of customer needs. Further, if one of our customers develops or acquires the internal capability to develop and produce critical systems or subsystems that we produce, the loss of that customer could have a material adverse effect on our business, financial condition and operating results. The introduction of new technologies and new market entrants may also increase competitive pressures.

We must achieve design wins to retain our existing customers and to obtain new customers.

New capital equipment typically has a lifespan of several years, and OEMs frequently specify which systems, subsystems, components and instruments are to be used in their equipment. Once a specific system, subsystem, component or instrument is incorporated into a piece of capital equipment, it will likely continue to be incorporated into that piece of equipment for at least several months before the OEM would be in a position to switch to the product of another supplier. Accordingly, it is important that our products are designed into the new capital equipment of OEMs, which we refer to as a design win, in order to retain our competitive position with existing customers and to obtain new customers.

We incur technology development and sales expenses with no assurance that our products will ultimately be designed into an OEM’s capital equipment. Further, developing new customer relationships, as well as maintaining and increasing our market share at existing customers, requires a substantial investment of our sales, engineering and management resources without any assurance from prospective customers that they will place significant orders. We believe that OEMs often consider long-term relationships in selecting and placing orders with suppliers. Accordingly, we may have difficulty achieving design wins from OEMs that are not currently our customers. Our operating results and potential growth could be adversely affected if we fail to achieve design wins with leading OEMs.

Defects in our products could damage our reputation, decrease market acceptance of our products, cause the unintended release of hazardous materials and result in potentially costly litigation or indemnification liability.

A number of factors, including design flaws, material and component failures, workmanship issues, contamination in the manufacturing environment, impurities in the materials used and unknown sensitivities to process conditions, such as temperature and humidity, as well as equipment failures, may cause our products to contain undetected errors or defects. Problems with our products may:

•

cause delays in product introductions and shipments for us or our customers;

•

result in increased costs and diversion of development resources;

•

cause us to incur increased charges due to unusable inventory;

•

require design modifications;

•

result in liability for the unintended release of hazardous materials or other damages to our or our customers’ property;

•

create claims for rework, replacement and/or damages under our contracts with customers, as well as indemnification claims from customers;

•

decrease market acceptance of, or customer satisfaction with, our products, which could result in decreased sales and product returns; or

•

result in lower yields for semiconductor manufacturers.

If any of our products contain defects or have reliability, quality or compatibility problems, our reputation might be damaged and customers might be reluctant to buy our products. We may also face a higher rate of product defects as we increase our production levels. Product defects could result in warranty and indemnification liability, the loss of existing customers or impair our ability to attract new customers. In addition, we may not find defects or failures in our products until after they are installed in a manufacturer’s fabrication facility. We may have to invest significant capital and other resources to correct these problems. Our current or potential customers also might seek to recover from us any losses resulting from defects or failures in our products. Hazardous materials flow through and are controlled by our products and an unintended release of these materials could result in serious injury or death. Liability claims could require us to spend significant time and money in litigation or pay significant damages or indemnification claims.

- 35 -

The technology labor market is very competitive, and our business will suffer if we are unable to hire and retain key personnel.

Our future success depends in part on the continued service of our key executive officers, as well as our research, engineering, sales, manufacturing and administrative personnel, most of whom are not subject to employment or non-competition agreements. In addition, competition for qualified personnel in the technology industry is intense, and we operate in geographic locations in which labor markets are particularly competitive.

Our business is particularly dependent on expertise which only a limited number of engineers possess. The loss of any of our key employees and officers, including our Chief Executive Officer (CEO), our Chief Financial Officer, any of our Senior Vice Presidents or any of the senior managers, or the failure to attract and retain new qualified employees, could adversely affect our business, operating results and financial condition. Further, our Chairman and (former) Chief Executive Officer, Clarence L. Granger retired as our CEO effective January 19, 2015. If our transition of Mr. Granger’s roles and responsibilities to our new CEO, James P. Scholhamer is not successful, our business, financial results and financial position could be materially adversely affected.

The challenges of employee retention has also increased during the integration process with AIT because of the necessity of combining personnel with varied business backgrounds and combining different corporate cultures and objectives, and several AIT employees, including members of AIT’s senior management, have left our company. The process of integrating operations and making such adjustments could cause an interruption of, or loss of momentum in, the activities of one or more of our businesses and the loss of key personnel. Employee uncertainty, lack of focus or turnover during the integration process may also disrupt our businesses. We may experience similar challenges with the integration of Marchi’s employees and business.

If we fail to maintain an effective system of internal controls, we might not be able to report our financial results accurately or prevent fraud; in that case, our stockholders could lose confidence in our financial reporting, which would harm our business and could negatively impact the price of our stock.

Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. In addition, Section 404 of the Sarbanes-Oxley Act of 2002 requires us and our independent registered public accounting firm to evaluate and report on our internal control over financial reporting. The process of maintaining and updating our internal controls and complying with Section 404 is expensive and time consuming, and requires significant attention from management and company resources. In addition, beginning in fiscal year 2013, we were required to evaluate and report on AIT’s internal controls and the attestation report we are required to obtain from our independent registered public accounting firm must include AIT’s internal control over financial reporting. Integrating AIT’s internal control framework into the Company and upgrading AIT’s controls to comply with the Sarbanes-Oxley Act has required substantial resources, and we cannot assure you that we will be able to successfully or effectively maintain adequate controls over our financial processes at AIT or for our consolidated business. In addition, even though we have concluded, and our independent registered public accounting firm has concurred, that our internal control over financial reporting provides reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles as of December 26, 2014, because of its inherent limitations, internal control over financial reporting may not prevent or detect fraud or misstatements, and our internal control may not be effective as of future periods. Failure to maintain existing or implement new or improved controls, or difficulties encountered in their implementation, could harm our results of operations or cause us to fail to meet our reporting obligations. If we or our independent registered public accounting firm discover a material weakness, the disclosure of that fact, even if quickly remedied, could reduce the market’s confidence in our financial statements and harm our stock price.

Fluctuations in currency exchange rates may adversely affect our financial condition and results of operations.

Our international sales are denominated primarily, though not entirely, in U.S. dollars. Many of the costs and expenses associated with our Chinese subsidiaries and Singapore subsidiary are paid in Chinese Renminbi and Singapore dollars, respectively, and we expect our exposure to Chinese Renminbi and Singapore dollars to increase as we increase production in those facilities. In addition, purchases of some of our components are denominated in Japanese Yen and Euros. Changes in exchange rates among other currencies in which our revenue or costs are denominated and the U.S. dollar may affect our revenue, cost of sales and operating margins. While fluctuations in the value of our revenue, cost of sales and operating margins as measured in U.S. dollars have not materially affected our results of operations historically, we do not currently hedge our foreign exchange exposure, and exchange rate fluctuations could have an adverse effect on our financial condition and results of operations in the future.

If environmental contamination were to occur in one of our manufacturing facilities, we could be subject to substantial liabilities.

We use substances regulated under various foreign, domestic, federal, state and local environmental laws in our manufacturing facilities. In addition, we may not be aware of or in compliance with all environmental laws or regulations that could subject us to liability in the U.S. or internationally. Our failure or inability to comply with existing or future environmental laws could result in significant remediation liabilities, the imposition of fines or the suspension or termination of the production of our products, and thus a material adverse impact on our business.

- 36 -

Our business is subject to the risks of earthquakes, fire, power outages, floods, and other catastrophic events, and to interruption by man-made disruptions, such as terrorism.

Our facilities could be subject to a catastrophic loss caused by natural disasters, including fires and earthquakes. We have facilities in areas with above average seismic activity, such as our manufacturing facility in South San Francisco, California and our manufacturing and headquarters facilities in Hayward, California. If any of our facilities were to experience a catastrophic loss, it could disrupt our operations, delay production and shipments, reduce revenue and result in large expenses to repair or replace the facility. In addition, we have in the past experienced, and may in the future experience, extended power outages at our facilities. We do not carry insurance policies that cover potential losses caused by earthquakes or other natural disasters or power loss.

In addition, disruption in supply resulting from natural disasters or other causalities or catastrophic events, such as earthquakes, severe weather such as storms or floods, fires, labor disruptions, power outages, terrorist attacks or political unrest, may result in certain of our suppliers being unable to deliver sufficient quantities of components or raw materials at all or in a timely manner, disruptions in our operations or disruptions in our customers’ operations. For example, in 2011, the northern region of Japan experienced a severe earthquake followed by a tsunami. These geological events caused significant damage in that region and adversely affected Japan’s infrastructure and economy. Some of our suppliers are located in Japan and they have experienced, and may experience in the future, shutdowns or disruptions as a result of these types of events, and their operations may be negatively impacted by these events. Many of our customers and suppliers are also located in California, and may be subject to the same risk of seismic activity as described for us above.

To the extent that natural disasters or other calamities or causalities should result in delays or cancellations of customer orders, or the delay in the manufacture or shipment of our products or services, our business, financial condition and operating results would be adversely affected.

Changes in tax rates or tax assets and liabilities could affect results of operations.

As a global company, we are subject to taxation in the United States and various other countries. Significant judgment is required to determine and estimate worldwide tax liabilities. Our future annual and quarterly tax rates could be affected by numerous factors, including changes in the: (1) applicable tax laws; (2) amount and composition of pre-tax income in countries with differing tax rates; or (3) valuation of our deferred tax assets and liabilities.

In addition, we are subject to regular examination by the Internal Revenue Service and other tax authorities, and from time to time we initiate amendments to previously filed tax returns. We regularly assess the likelihood of favorable or unfavorable outcomes resulting from these examinations and amendments to determine the adequacy of our provision for income taxes, which requires estimates and judgments. Although we believe our tax estimates are reasonable, there can be no assurance that the tax authorities will agree with such estimates. We may have to engage in litigation to achieve the results reflected in the estimates, which may be time-consuming and expensive. There can be no assurance that we will be successful or that any final determination will not be materially different from the treatment reflected in our historical income tax provisions and accruals, which could materially and adversely affect our financial condition and results of operations.

We are currently enjoying a zero rate tax holiday in Singapore that is scheduled to expire at the end of fiscal year 2015. This tax rate is subject to achieving certain commitments agreed to with the Singapore tax authorities, including investment and employment thresholds, and our tax rate could be significantly affected if we are unable to meet these commitments or if we are unable to favorably renegotiate the commitment requirements.

The market for our stock is subject to significant fluctuation.

The size of our public market capitalization is relatively small, and the average volume of our shares that are traded is relatively low. The market price of our common stock could be subject to significant fluctuations. Among the factors that could affect our stock price are:

•

quarterly variations in our operating results;

•

our ability to successfully introduce new products and manage new product transitions;

•

changes in revenue or earnings estimates or publication of research reports by analysts;

•

speculation in the press or investment community;

•

strategic actions by us, our customers or our competitors, such as acquisitions or restructurings;

- 37 -

•

announcements relating to any of our key customers, significant suppliers or the semiconductor manufacturing and capital equipment industry generally;

•

general market conditions;

•

the effects of war and terrorist attacks; and

•

domestic and international economic factors unrelated to our performance.

The stock markets in general, and the markets for technology stocks in particular, have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock.

New regulations related to conflict minerals could adversely impact our business.

The Dodd-Frank Wall Street Reform and Consumer Protection Act contains provisions to improve transparency and accountability concerning the supply of certain minerals, known as conflict minerals, originating from the Democratic Republic of Congo (DRC) and adjoining countries. As a result, in August 2012 the SEC adopted annual disclosure and reporting requirements for those companies who use conflict minerals mined from the DRC and adjoining countries in their products. These requirements require us to perform on-going due diligence efforts on our supply chain and require public disclosure of the nature and results of these efforts. We filed our most recent conflict minerals report on Form SD on June 1, 2015 reporting that we could not yet determine whether the conflict minerals we source were, directly or indirectly, used to finance or benefit armed groups in the Covered Countries. There have been and there will be costs associated with complying with these disclosure requirements to determine the sources of conflict minerals used in our products and other potential changes to products, processes or sources of supply as a consequence of such verification activities. Complying with these rules could adversely affect the sourcing, supply and pricing of materials used in our products and result in substantial additional costs. As there may be only a limited number of suppliers offering “conflict free” conflict minerals, we cannot be sure that we will be able to obtain necessary conflict minerals from such suppliers in sufficient quantities or at competitive prices. Also, we may face reputational challenges if we determine that certain of our products contain minerals not determined to be conflict free or if we are unable to sufficiently verify the origins for all conflict minerals used in our products through the procedures we may implement. In addition, if we are unable to comply with these rules, we could be subject to enforcement actions by the Securities and Exchange Commission and liability under the Securities Exchange Act of 1934, as amended, which could result in material adverse consequences to our business, as well as significant fines and penalties.

If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse opinion regarding our stock, our stock price and trading volume could decline.

The trading market for our common stock is influenced by the research and reports that industry or securities analysts publish about us or our business. If any of the analysts who cover us issue an adverse opinion regarding our stock, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

We do not currently intend to pay dividends on our common stock and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

We do not intend to declare and pay dividends on our capital stock for the foreseeable future. We currently intend to invest our future earnings, if any, to fund our growth. Additionally, the terms of the credit agreement we entered into in February 2015 restrict our ability to pay dividends. Therefore, you are not likely to receive any dividends on your common stock for the foreseeable future.
