NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 — Basis of Presentation and New Accounting Pronouncements

Basis of Presentation

The accompanying condensed consolidated financial information ~~included herein~~of FormFactor, Inc. is unaudited and has been prepared ~~by FormFactor, Inc. without audit,~~ in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange ~~Commission (“SEC”).~~Commission. However, such information reflects all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods. The financial information as of December ~~30, 2017~~29, 2018 is derived from our ~~2017~~2018 Annual Report on Form 10-K. The condensed consolidated financial statements included herein should be read in conjunction with the consolidated financial statements and the notes thereto included in our ~~2017~~2018 Annual Report on Form 10-K. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year.

Fiscal Year

We operate on a 52/53 week fiscal year, whereby the fiscal year ends on the last Saturday of December. Fiscal ~~2018~~2019 and ~~2017~~2018 each contain 52 weeks and the three months ended March 30, 2019 and March 31, 2018 ~~and April 1, 2017~~ each contained 13 weeks. Fiscal ~~2018~~2019 will end on December ~~29, 2018.~~28, 2019.

Reclassifications

Certain immaterial reclassifications were made to the prior period financial statements to conform to the current period presentation.

Critical Accounting Policies

Our critical accounting policies have not changed during the three months ended March ~~31, 2018~~30, 2019 from those disclosed in our Annual Report on Form 10-K for the year ended December ~~30, 2017, except for:~~

~~Revenue Recognition~~

Revenue is recognized upon transferring control of products and services, and the amounts recognized reflect the consideration we expect to be entitled to receive in exchange for these products and services. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. An arrangement may include some or all of the following products and services: probe cards, systems, accessories, installation services, service contracts and extended warranty contracts. We sell our products and services direct to customers and to partners in two distribution channels: global direct sales force and through a combination of manufacturers’ representatives and distributors.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. In contracts with multiple performance obligations, we identify each performance obligation and evaluate whether the performance obligation is distinct within the context of the contract at contract inception. Performance obligations that are not distinct at contract inception are combined and accounted for as one unit of account. Generally, the performance obligations in a contract are considered distinct within the context of the contract and are accounted for as separate units of account.

Our products may be customized to our customers’ specifications, however, control of our products are typically transferred to the customer at the point in time the product is either shipped or delivered, depending on the terms of the arrangement, as the criteria for overtime recognition are not met. In limited circumstances, substantive acceptance by the customer exists which results in the deferral of revenue until acceptance is formally received from the customer. Judgment may be required in determining if the acceptance clause is substantive.

Installation services are routinely provided to customers purchasing our systems. Installation services are a distinct performance obligation apart from the systems and recognized in the period they are performed. Service contracts, which include repair and maintenance service contracts, and extended warranty contracts are also distinct performance obligations and recognized as our performance obligations are satisfied. This is typically the contractual service period, which ranges from one to two years. For these service contracts recognized over time, we use an input measure, days elapsed, to measure progress.

A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. In determining the transaction price, we evaluate whether the price is subject to refund or adjustment to determine the net consideration to which we expect to be entitled. We generally do not grant return privileges, except

for defective products during the warranty period. Sales incentives and other programs that we may make available to these customers are considered to be a form of variable consideration, which is estimated in determining the contract’s transaction price to be allocated to the performance obligations. We have elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component as our standard payment terms are less than one year.

For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation based on its relative standalone selling price. The stand-alone selling prices are determined based on the prices at which we separately sell these products. For items that are not sold separately, we estimate the stand-alone selling prices using our best estimate of selling price.

~~Transaction price allocated to the remaining performance obligations:~~ On March 31, 2018, we had $3.6 million of remaining performance obligations, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. We expect to recognize approximately 20.6% of our remaining performance obligations as revenue in fiscal 2019, and additional 8.7% in fiscal 2020 and thereafter. The foregoing excludes the value of other remaining performance obligations as they have original durations of one year or less, and also excludes information about variable consideration allocated entirely to a wholly unsatisfied performance obligation.

~~Contract balances:~~ The timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable is recorded at the invoiced amount, net of an allowance for doubtful accounts. A receivable is recognized in the period we deliver goods or provide services or when our right to consideration is unconditional. A contract asset is recorded when we have performed under the contract but our right to consideration is conditional on something other than the passage of time. Contract assets as of March 31, 2018 and December 30, 2017 were $1.5 million and $1.6 million, respectively, and are reported on the Condensed Consolidated Balance Sheet as a component of Prepaid expenses and other current assets.

Contract liabilities include payments received in advance of performance under a contract and are satisfied as the associated revenue is recognized. Contract liabilities are reported on the Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period as a component of Deferred revenue and Deferred rent and other liabilities. Contract liabilities as of March 31, 2018 and December 30, 2017 were $5.2 million and $5.7 million, respectively. During the period ended March 31, 2018, we recognized $2.4 million of revenue that was included in contract liabilities as of December 30, 2017.

~~Costs to obtain a contract:~~ ~~We generally expense sales commissions when incurred as a component of Selling, general and administrative expense as the amortization period is typically less than one year.~~

~~Revenue by Category:~~ ~~Refer to Note 12 of Notes to Consolidated Financial Statements for further details.~~29, 2018.

New Accounting Pronouncements

ASU ~~2016-10, ASU 2015-14 and ASU 2014-09~~2018-15

In ~~May 2014,~~August 2018, the Financial Accounting Standard Board ("FASB") issued Accounting Standards Update ("ASU") ~~No. 2014-09,~~2018-15, "~~Revenue from Contracts with Customers,~~Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ~~and, in August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,~~” which defers the effective date of ASU 2014-09 by one year. ASU 2014-09 requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The new guidance also requires expanded disclosures relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The standard permits the use of either the retrospective or modified retrospective transition methods. In April 2016, the FASB issued ASU 2016-10, “~~Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing~~” which was issued to clarify ASC Topic 606, “Revenue from Contracts with Customers” related to (i) identifying performance obligations; and (ii) the licensing implementation guidance. We adopted Accounting Standards Codification (“ASC”) 606, ~~Revenue from Contracts with Customers~~ and all related amendments (collectively “ASC 606”), on December 31, 2017, the first day of fiscal 2018, using the modified retrospective method. We applied ASC 606 to all contracts not completed as of the date of adoption in order to determine any adjustment to the opening balance of retained earnings. Under the modified retrospective adoption method, the comparative financial information has not been restated and continues to be reported underclarifies the accounting ~~standards~~for implementation costs in ~~effect for those periods, ASC 605, "Revenue Recognition", which is also referred to herein as "legacy GAAP."~~

The adoption of ASC 606 did not have a material impact on our consolidated financial statements as of December 31, 2017. No adjustment was recorded to accumulated deficit as of the adoption date and reported revenue would not have been different under

~~legacy GAAP. Additionally, we do not expect the adoption of the revenue standard to have a material impact to our net income on an ongoing basis.~~

cloud computing arrangements. ASU ~~2017-12~~

~~In August 2017, the FASB issued ASU2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities~~," which changes the recognition and presentation requirements of hedge accounting, including eliminating the requirement to separately measure and report hedge ineffectiveness and changing the presentation to include all items that affect earnings in the same income statement line item as the hedged item. ASU 2017-12 also provides new alternatives for applying hedge accounting to additional hedging strategies, measuring the hedged item in fair value hedges of interest rate risk, reducing the cost and complexity of applying hedge accounting and reducing the risk of material error correction if a company applies the shortcut method inappropriately. ASU 2017-122018-15 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, ~~2018,~~2019. Early adoption is permitted. ASU 2018-15 should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We have not yet determined the impact of this standard on ~~a prospective basis. We early adopted ASU 2017-12 on December 31, 2017, the first day of fiscal 2018, resulting in an immaterial adjustment in~~ our ~~accumulated deficit on December 30, 2017. The adjustment was reflected in our Condensed Consolidated Balance Sheets as of that date.~~financial statements.

ASU ~~2017-09~~2016-02, ASU 2018-10, ASU 2018-11 and ASU 2019-01

~~In May 2017, the FASB issued ASU 2017-09, "Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting,~~" which provides clarity and reduces both diversity in practice and the cost and complexity when accounting for a change to the terms of a stock-based award. ASU 2017-09 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017, on a prospective basis. We adopted ASU 2017-09 on December 31, 2017, the first day of fiscal 2018. There were no modifications to any stock-based awards during the three months ended March 31, 2018.

~~ASU 2017-04~~

~~In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment,~~" which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, if applicable. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. The same impairment test also applies to any reporting unit with a zero or negative carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. ASU 2017-04 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2019, on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. We do not expect the adoption of ASU 2017-04 to have a material effect on our financial position, results of operations or cash flows.

~~ASU 2016-18~~

~~In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230) - Restricted Cash,~~" which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, an entity should include amounts generally described as restricted cash or restricted cash equivalents within cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Prior to this ASU, there was no guidance to address how to classify and present changes in restricted cash or restricted cash equivalents. The updated guidance is effective for interim and annual periods beginning after December 15, 2017. We adopted ASU 2016-18 as of December 31, 2017, the first day of fiscal 2018 and retrospectively applied such guidance to our Consolidated Statements of Cash Flows.

The following table provides a reconciliation of Cash and cash equivalents as previously reported within the Condensed Consolidated Statements of Cash Flows to Cash, cash equivalents and restricted cash as currently reported in the Condensed Consolidated Statements of Cash Flows (in thousands):

December 30, 2017 April 1, 2017 December 31, 2016

Cash, cash equivalents and restricted cash as currently reported in the Condensed Consolidated Statements of Cash Flows $ 92,726
$ 115,557
$ 102,596

~~As of March 31, 2018, Restricted cash was comprised primarily of funds held by our foreign subsidiaries for employee obligations, office leases and customer deposits.~~

~~ASU 2016-02~~

In February 2016, the FASB issued ASU 2016-02, ~~"Leases,~~"Leases (Topic 842)," which requires the recognition of right-of-use assets and lease liabilities for all long-term leases, including operating leases, on the balance sheet. ~~The new standard also~~ASU 2016-02 was amended in July 2018 by both ASU 2018-10, "Codification Improvements to Topic 842, Leases," and ASU 2018-11, "Leases (Topic 842): Targeted Improvements" and in March 2019 by ASU 2019-01, "Leases (Topic 842): Codification Improvements." ASU 2016-02 provides additional guidance on the measurement of the right-of-use assets and lease liabilities and ~~will require~~requires enhanced disclosures about ~~the Company’s~~our leasing arrangements. Under current accounting standards, substantially all of the Company’s leases are considered operating leases and, as such, are not recognized on the Consolidated Balance Sheet. This new standard is effective for the Company beginning on January 1, 2019, with early adoption permitted. As initially issued, the standard required a “modified retrospective” adoption, meaning the standard is applied to leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. In March 2019, the FASB approved an amendment toWe adopted Topic 842 ~~that~~and all related amendments on December 30, 2018, the first day of fiscal 2019, using the modified transition approach. The modified transition approach permits a company to use its effective date as the date of initial application to apply the standard to its leases, and, therefore, not restate comparative prior period financial information. ~~The Company~~Consequently, prior period financial information is ~~currently assessing~~not updated, and the ~~impact of~~disclosures required under the new standard will not be provided for dates and periods before December 30, 2018. The standard provides several optional practical expedients in transition. We elected the ‘package of practical expedients,’ which permits us to not reassess, under the new standard, our prior conclusions about lease identification, lease classification and initial direct costs. We did not elect the use-of-hindsight or the practical expedient pertaining to land easements; the latter not being applicable to us. The new standard also provides practical expedients for an entity’s ongoing accounting. We elected the short-term lease recognition exemption. This means, for those leases that qualify, we will not recognize a right-of-use asset or lease liability, and this includes not recognizing right-of-use assets or lease liabilities for existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all our leases. The adoption of the lease standard did not have any effect on ~~its~~ our previously reported Condensed

Consolidated ~~Financial~~ Statements of Operations and ~~has~~did not ~~yet determined its transition method.~~result in a cumulative catch-up adjustment to opening equity. See Note 12 for additional information.

Note 7 — Fair Value and Derivative Instruments

Whenever possible, the fair values of our financial assets and liabilities are determined using quoted market prices of identical securities or quoted market prices of similar securities from active markets. The three levels of inputs that may be used to measure fair value are as follows:

Level 1 valuations are obtained from real-time quotes for transactions in active exchange markets involving identical securities;

Level 2 valuations utilize significant observable inputs, such as quoted prices for similar assets or liabilities, quoted prices near the reporting date in markets that are less active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

Level 3 valuations utilize unobservable inputs to the valuation methodology and include our own data about assumptions market participants would use in ~~ricing~~pricing the asset or liability based on the best information available under the circumstances.

We did not have any transfers of assets or liabilities measured at fair value on a recurring basis to or from Level 1, Level 2 or Level 3 during the three months ended March ~~31, 2018~~30, 2019 or the year ended December ~~30, 2017.~~29, 2018.

The carrying values of Cash, Accounts receivable, net, Restricted cash, Prepaid expenses and other current assets, Accounts payable and Accrued liabilities approximate fair value due to their short maturities.

No changes were made to our valuation techniques during the first three months of fiscal ~~2018.~~

Cash Equivalents

The fair value of our cash equivalents is determined based on quoted market prices for similar or identical securities.

Marketable Securities

We classify our marketable securities as available-for-sale and value them utilizing a market approach. Our investments are priced by pricing vendors who provide observable inputs for their pricing without applying significant judgment. Broker pricing is used mainly when a quoted price is not available, the investment is not priced by our pricing vendors or when a broker price is more reflective of fair value. Our broker-priced investments are categorized as Level 2 investments because fair value is based on similar assets without applying significant judgments. In addition, all of our investments have a sufficient level of trading volume to demonstrate that the fair value is appropriate.

Unrealized gains and losses were immaterial and were recorded as a component of Accumulated other comprehensive income in

our Condensed Consolidated Balance Sheets. We did not have any other-than-temporary unrealized gains or losses at either period end included in these financial statements.

Interest Rate Swaps

The fair value of our interest rate swap contracts is determined at the end of each reporting period based on valuation models that use interest rate yield curves as inputs. For accounting purposes, our interest rate swap contracts qualify for, and are designated as, cash flow hedges. The cash flows associated with the interest rate swaps are reported in Net cash provided by operating activities in our Condensed Consolidated Statements of Cash Flows and the fair value of the interest rate swap contracts inare recorded within Prepaid expenses and other current assets and Other assets in our Condensed Consolidated Balance Sheets.

The impact of the interest rate swaps on our Condensed Consolidated Statements of Income was as follows (in thousands):

Foreign Exchange Derivative Contracts

We operate and sell our products in various global markets. As a result, we are exposed to changes in foreign currency exchange rates. We utilize foreign currency forward contracts to hedge against future movements in foreign exchange rates that affect certain existing foreign currency denominated assets and liabilities and forecasted foreign currency revenue and expense transactions. Under this program, our strategy is to have increases or decreases in our foreign currency exposures mitigated by gains or losses on the foreign currency forward contracts in order to mitigate the risks and volatility associated with foreign currency transaction gains or losses.

We do not use derivative financial instruments for speculative or trading purposes. For accounting purposes, certain of our foreign currency forward contracts are not designated as hedging instruments and, accordingly, we record the fair value of these contracts as of the end of our reporting period in our Condensed Consolidated Balance Sheets with changes in fair value recorded within Other ~~expense,~~income (expense), net in our Condensed Consolidated Statement of Income for both realized and unrealized gains and losses. Certain of our foreign currency forward contracts are designated as cash flow hedges, and, accordingly, we record the fair value of these contracts as of the end of our reporting period in our Condensed Consolidated Balance Sheets with changes in fair value recorded as a component of accumulated other comprehensive income and reclassified into earnings in the same period in which the hedged transaction affects earnings, and in the same line item on the Condensed Consolidated Statements of Income as the impact of the hedge transaction. At March 30, 2019, we expect to reclassify $0.4 million of the amount accumulated in other comprehensive income (loss) to earnings during the next 12 months, due to the recognition in earnings of the hedged forecasted transactions.

The fair value of our foreign exchange derivative contracts was determined based on current foreign currency exchange rates and forward points. All of our foreign exchange derivative contracts outstanding at March ~~31, 2018~~30, 2019 will mature in the ~~second~~fourth quarter of fiscal ~~2018.~~2019.

The following table provides information about our foreign currency forward contracts outstanding as of March ~~31, 2018~~30, 2019 (in thousands):

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

We measure and report goodwill and intangible assets at fair value on a non-recurring basis if we determine these assets to be impaired or in the period when we make a business acquisition. There were no assets or liabilities measured at fair value on a nonrecurring basis during the three months ended March 30, 2019 or March 31, ~~2018 or April 1, 2017.~~2018.

Note 8 — Warranty

We offer warranties on certain products and record a liability for the estimated future costs associated with warranty claims at the time revenue is recognized. The warranty liability is based upon historical experience and our estimate of the level of future costs. While we engage in product quality programs and processes, our warranty obligation is affected by product failure rates, material usage and service delivery ~~costs incurred in correcting a product failure.~~costs. We continuously monitor product returns for warranty and maintain a reserve for the related expenses based upon our historical experience and any specifically identified ~~field~~ failures. As we sell new products to our customers, we must exercise considerable judgment in estimating the expected failure rates. This estimating process is based on historical experience of similar products, as well as various other assumptions that we believe to be reasonable under the circumstances.

We provide for the estimated cost of product warranties at the time revenue is recognized as a component of Cost of revenues in our Condensed Consolidated Statement of Income.

Note 9 — Stockholders’ Equity and Stock-Based Compensation

Common Stock Repurchase Program

In February 2017, our Board of Directors authorized a program to repurchase up to $25 million of outstanding common stock to offset potential dilution from issuances of common stock under our employee stock purchase plan and equity incentive plan. The share repurchase program will expire on February 1, 2020. Repurchased shares are retired upon the settlement of the related transactions with the excess of cost over par value charged to additional paid-in capital. All repurchases are made in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.

During the three months ended March ~~31, 2018,~~30, 2019, we did not repurchase any shares. As of March ~~31, 2018,~~30, 2019, $6.0 million remained available for future repurchases.

Contractual Commitments and Purchase Obligations

Our ~~lease commitments,~~ purchase obligations and other contractual obligations have not materially changed as of March ~~31, 2018~~30, 2019 from those disclosed in our Annual Report on Form 10-K for the year ended December ~~30, 2017.~~29, 2018.

Legal Matters

From time to time, we may be subject to legal proceedings and claims in the ordinary course of business. As of March ~~31, 2018,~~30, 2019, and as of the filing of this Quarterly Report on Form 10-Q, we were not involved in any material legal proceedings.

Note 12 — Leases

We lease real estate space under non-cancelable operating lease agreements for commercial and industrial space, as well as our corporate headquarters located in Livermore, California. Our leases have remaining terms of 1 to 10 years, and some leases include options to extend up to 20 years. We also have operating leases for automobiles with remaining lease terms of 1 to 4 years. We did not include any of our renewal options in our lease terms for calculating our lease liability as the renewal options allow us to maintain operational flexibility and we are not reasonably certain we will exercise these options at this time. The weighted-average remaining lease term for our operating leases was 8 years at March 30, 2019 and the weighted-average discount rate was 4.7%.

Note 1213 — Revenue

Transaction price allocated to the remaining performance obligations: On March 30, 2019, we had $3.9 million of remaining performance obligations, which were comprised of deferred service contracts and extended warranty contracts not yet delivered. We expect to recognize approximately 74% of our remaining performance obligations as revenue in the remainder of fiscal 2019, and approximately 26% in fiscal 2020 and thereafter. The foregoing excludes the value of other remaining performance obligations as they have original durations of one year or less, and also excludes information about variable consideration allocated entirely to a wholly unsatisfied performance obligation.

Contract balances: The timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable is recorded at the invoiced amount, net of an allowance for doubtful accounts. A receivable is recognized in the period we deliver goods or provide services or when our right to consideration is unconditional. A contract asset is recorded when we have performed under the contract but our right to consideration is conditional on something other than the passage of time. Contract assets as of March 30, 2019 and December 29, 2018 were $0.6 million and $0.3 million, respectively, and are reported on the Condensed Consolidated Balance Sheets as a component of Prepaid expenses and other current assets.

Contract liabilities include payments received in advance of performance under a contract and are satisfied as the associated revenue is recognized. Contract liabilities are reported on the Condensed Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period as a component of Deferred revenue and Other liabilities. Contract liabilities as of March 30, 2019 and December 29, 2018 were $7.6 million and $5.7 million, respectively. During the three months ended March 30, 2019, we recognized $1.4 million of revenue that was included in contract liabilities as of December 29, 2018.

Costs to obtain a contract: We generally expense sales commissions when incurred as a component of Selling, general and administrative expense as the amortization period is typically less than one year.

Revenue by Category: Refer to Note 14 of Notes to Consolidated Financial Statements for further details.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Cautionary Statement Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Securities Exchange Act of 1934 and the Securities Act of 1933, which are subject to risks and uncertainties. The forward-looking statements include statements concerning, among other things, our business strategy, financial and operating results, gross margins, liquidity and capital expenditure requirements, impact of accounting standards and our share repurchase plan. In some cases, you can identify these statements by forward-looking words, such as "may," "might," "will," "could," "should," "expect," "plan," "anticipate," "believe," "estimate," "predict," "intend" and "continue," the negative or plural of these words and other comparable terminology.

The forward-looking statements are only predictions based on our current expectations and our projections about future events. All forward-looking statements included in this Quarterly Report on Form 10-Q are based upon information available to us as of the filing date of this Quarterly Report on Form 10-Q. You should not place undue reliance on these forward-looking statements. We have no obligation to update any of these statements. These forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to differ materially from those expressed or implied by these statements, including risks related to general market trends, our ability to execute our business strategy and other risks discussed in the section titled “Risk Factors” and elsewhere in our Annual Report on Form 10-K for the year ended December ~~30, 2017~~29, 2018 and in this Quarterly Report on Form 10-Q. You should carefully consider the numerous risks and uncertainties described under these sections.

The following discussion and analysis should be read in conjunction with our condensed consolidated financial statements and the accompanying notes contained in this Quarterly Report on Form 10-Q.

The ~~decrease~~increase in net income was primarily due to ~~decreased~~increased revenue from our Probe Cards segment, ~~and increased operating expenses,~~ partially offset by ~~improved gross margins.~~higher operating expenses and higher provision for income taxes.

Critical Accounting Policies and the Use of Estimates

Management’s Discussion and Analysis and Note 2 to the Consolidated Financial Statements in our ~~2017~~2018 Annual Report on Form 10-K describe the significant accounting estimates and critical accounting policies used in preparation of the Consolidated Financial Statements. Actual results in these areas could differ from management’s estimates. During the three months ended March ~~31, 2018, other than the adoption of new revenue recognition guidance as described in Note 1,~~30, 2019, there were no significant changes in our critical accounting policies or estimates from those reported in our Annual Report on Form 10-K for the year ended December ~~30, 2017,~~29, 2018, which was filed with the Securities and Exchange Commission on February ~~27, 2018.~~26, 2019.

The increase in Systems Segment revenue for the three months ended March 31, 2018 compared to the three months ended April 1, 2017 was driven by increased unit sales of thermal sub-systems due to increased customer demand, offset partially by lower revenue from probe stations due to changes in product sales mix which decreased the average selling price of unit sold.

Geographic revenue information is based on the location to which we ship the product. For example, if a certain South Korean customer purchases through their U.S. subsidiary and requests the products to be shipped to an address in South Korea, this sale will be reflected in the revenue for South Korea rather than U.S.

Changes in revenue by geographic region for the three months ended March ~~31, 2018~~30, 2019 compared to the three months ended ~~April 1, 2017~~March 31, 2018 were primarily attributable to changes in customer demand, shifts in customer regional manufacturing strategies, and product sales ~~mix as previously described.~~mix.

Cost of Revenues and Gross Margins

Cost of revenues consists primarily of manufacturing materials, ~~payroll,~~compensation and benefits, shipping and handling costs, manufacturing-related overhead and amortization of certain intangible assets. Our manufacturing operations rely on a limited number of suppliers to provide key components and materials for our products, some of which are a sole source. We order materials and supplies based on backlog and forecasted customer orders. Tooling and setup costs related to changing manufacturing lots at our suppliers are also included in the cost of revenues. We expense all warranty costs, inventory provisions and amortization of certain intangible assets as cost of revenues.

Corporate and Other includes unallocated expenses relating to amortization of intangible assets, share-based compensation expense, acquisition-related costs, including charges related to inventory stepped up to fair value, and other costs, which are not used in evaluating the results of, or in allocating resources to, our reportable segments. Acquisition-related costs include transaction costs and any costs directly related to the acquisition and integration of acquired businesses.

Liquidity and Capital Resources

Capital Resources

Our working capital was ~~$215.2~~$237.7 million at March ~~31, 2018~~30, 2019, which did not change significantly ~~with $213.7~~compared to $235.3 million at December ~~30, 2017.~~29, 2018.

Cash and cash equivalents primarily consist of deposits held at banks and money market funds. Marketable securities primarily consist of U.S. agency securities and corporate bonds. We typically invest in highly-rated securities with low probabilities of default. Our investment policy requires investments to be rated single A or better, and limits the types of acceptable investments, issuer concentration and duration of the investment.

Our cash, cash equivalents and marketable securities totaled approximately ~~$142.1~~$159.8 million at March ~~31, 2018, as~~30, 2019, compared to ~~$140.2~~$149.0 million at December ~~30, 2017.~~29, 2018. We believe that we will be able to satisfy our working capital requirements and scheduled term loan repayments for at least the next twelve months with the liquidity provided by our existing cash, cash equivalents, marketable securities and cash provided by operations. To the extent necessary, we may consider entering into short and long-term debt

obligations, raising cash through a stock issuance, or obtaining new financing facilities, which may not be available on terms favorable to us. Our future capital requirements may vary materially from those now planned.

If we are unsuccessful in maintaining or growing our revenues, maintaining or reducing our cost structure (in response to an industry demand downturn or other event), or increasing our available cash through debt or equity financings, our cash, cash equivalents and marketable securities may decline in fiscal ~~2018.~~2019.

We utilize a variety of tax planning and financing strategies ~~in an effort~~ to manage our worldwide cash and deploy funds to locations where ~~they are~~ needed. As part of these strategies, we indefinitely reinvest a ~~significant~~ portion of our foreign ~~earnings and our current plans do not demonstrate a need to repatriate these~~ earnings. Should we require additional capital in the United States, we may elect to repatriate indefinitely-reinvested foreign funds or raise capital in the United States.

Operating Activities

Net cash provided by operating activities for the three months ended March ~~31, 2018~~30, 2019 was primarily attributable to ~~our operations generating $18.3 million of cash (a~~ net income of ~~$2.1~~$5.5 million ~~which included $16.2~~and $20.6 million of net non-cash ~~expenses),~~expenses, offset by operating assets and liabilities using ~~$9.0~~$5.5 million of cash as discussed in more detail below.

Accrued liabilities decreased ~~$10.2~~$5.2 million to ~~$23.5~~$22.6 million at March ~~31, 2018~~30, 2019, compared to ~~$33.7~~$27.7 million at December ~~30, 2017~~29, 2018, as a result of timing of employee payroll, decreases in ~~accruals for~~ employee stock purchase plan ~~salaries~~withholdings due to timing within the plan's withholding period, and ~~bonuses.~~a decrease in accrued sales taxes due to timing of payments.

Investing Activities

Net cash used in investing activities for the three months ended March ~~31, 2018~~30, 2019 was primarily related to ~~$3.8~~$6.0 million of cash used in the acquisition of property, plant and equipment, ~~partially offset by $0.4~~as well as $3.3 million of net ~~maturities~~purchases of marketable securities.

Financing Activities

Net cash used in financing activities for the three months ended March ~~31, 2018~~30, 2019 primarily related to ~~$8.8~~$7.5 million of principal payments made towards the repayment of our term loan and ~~$0.4~~$0.3 million related to tax withholdings associated with the net share settlements of our equity awards, partially offset by ~~$4.8~~$3.9 million of proceeds received from issuances of common stock under our employee stock purchase plan and ~~exercise of~~ stock ~~options.~~option plans.

Debt Facility

On June 24, 2016, we entered into a credit agreement (the “Credit Agreement”) with HSBC Bank USA, National Association ("HSBC"). Pursuant to the Credit Agreement, the lenders provided us with a senior secured term loan facility of $150 million (the “Term Loan”). The proceeds of the Term Loan were used to finance a portion of the purchase price paid in connection with the acquisition of Cascade Microtech.

The Term Loan bears interest at a rate equal to, at our option, (i) the applicable London Interbank Offered Rate ("LIBOR") rate plus 2.00% per annum or (ii) Base Rate (as defined in the Credit Agreement) plus 1.00% per annum. We have currently elected to pay interest at 2.00% over the one-month LIBOR rate. Interest payments are payable in ~~quarterly~~monthly installments over a five-year period.

On July 25, 2016 we entered into an interest rate swap agreement with HSBC and other lenders to hedge the interest payments on the Term Loan for the notional amount of $95.6 million. As future levels of LIBOR over the life of the loan are uncertain, we entered into these interest-rate swap agreements to hedge the exposure in interest rate risks associated with movement in LIBOR rates. By entering into the agreements, we convert a floating rate interest at one-month LIBOR plus 2% into a fixed rate interest at 2.939%. As of March 30, 2019, the notional amount of the loan that is subject to this interest rate swap is $45.0 million. See Note 7 of Notes to Condensed Consolidated Financial Statements for additional information.

~~period.~~ The Term Loan amortizes in equal quarterly installments, which began June 30, 2016, in annual amounts equal to 5% for year one, 10% for year two, 20% for year three, 30% for year four and 35% for year five. The Credit Agreement allows voluntary prepayment to be made at any time to prepay the Term Loan in whole or in part without penalty or premium. As of March 30, 2019, we have made prepayments of $40.0 million in addition to scheduled installments per the Credit Agreement. For the three months ended March 30, 2019, we did not make any prepayments in addition to scheduled installments.

The obligations under the Term Loan are guaranteed by substantially all of our assets and the assets of our domestic subsidiaries, subject to certain customary exceptions.

The Credit Agreement contains negative covenants customary for financing of this type, as well as certain financial maintenance covenants. As of March ~~31, 2018,~~30, 2019, the balance outstanding pursuant to the ~~term loan~~Term Loan was ~~$97.5~~$57.5 million at an interest rate of ~~3.65%~~4.5% and we were in compliance with all covenants under the Credit Agreement.

The Credit Agreement allows voluntary prepayment to be made at any time and from time to time to prepay the Term Loan in whole or in part without penalty or premium. As of March 31, 2018, we have made prepayments of $30.0 million in addition to scheduled installments per the Credit Agreement. For the three months ended March 31, 2018, we made prepayment of $5.0 million in addition to scheduled installment.

Stock Repurchase Program

In February 2017, our Board of Directors authorized a program to repurchase up to $25 million of outstanding common stock to offset potential dilution from issuances of common stock under our stock-based compensation plans. The share repurchase program will expire on February 1, 2020. During the three months ended March ~~31, 2018,~~30, 2019, we did not repurchase any shares of common stock. As of March ~~31, 2018,~~30, 2019, $6.0 million remained available for future repurchases.

Repurchased shares are retired upon the settlement of the related trade transactions with the excess of cost over par value charged to additional paid-in capital. All repurchases were made in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.

Contractual Obligations and Commitments

~~Our~~Other than our operating lease commitments as disclosed in Note 12 of Notes to Condensed Consolidated Financial Statements, our contractual obligations and commitments have not materially changed as of March ~~31, 2018~~30, 2019 from those disclosed in our Annual Report on Form 10-K for the year ended December ~~30, 2017.~~29, 2018.

Off-Balance Sheet Arrangements

Historically, we have not participated in transactions that have generated relationships 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. As of March ~~31, 2018,~~30, 2019, we were not involved in any such off-balance sheet arrangements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

For financial market risks related to changes in interest rates and foreign currency exchange rates, reference is made to Item 7A “Quantitative and Qualitative Disclosures about Market Risk” contained in Part II of our Annual Report on Form 10-K for the fiscal year ended December ~~30, 2017.~~29, 2018. Our exposure to market risk has not changed materially since December ~~30, 2017.~~29, 2018.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), as of the end of the period covered by this report, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”)) are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

~~Beginning~~As of December ~~31, 2017,~~30, 2018, we implemented ~~ASC 606, "Revenue from Contracts with Customers", which required the implementation of~~ internal controls to ensure we adequately evaluated our contracts and properly ~~assessed~~valued the ~~impact on~~right-of-use assets and lease liabilities for the new accounting ~~standard. In addition, although the new revenue~~ standard ~~is expected~~related to ~~have an immaterial impact~~leases on our ~~ongoing revenue~~financial statements. There have been no other changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or ~~net income, we implemented changes~~are likely to materially affect, our ~~policies and~~ internal ~~controls related to revenue recognition.~~control over financial reporting.

Limitations on the Effectiveness of Controls

Control systems, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control systems’ objectives are being met. Further, the design of any control systems must reflect the fact that there are resource constraints, and the benefits of all controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of a simple error or mistake. Control systems can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based, in part, on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

CEO and CFO Certifications

We have attached as exhibits to this Quarterly Report on Form 10-Q the certifications of our Chief Executive Officer and Chief Financial Officer, which are required in accordance with the Exchange Act. We recommend that this Item 4 be read in conjunction with the certifications for a more complete understanding of the subject matter presented.

PART II - OTHER INFORMATION

Item 1A. Risk Factors

There have been no material changes during the three months ended March ~~31, 2018~~30, 2019 to the risk factors discussed in our Annual Report on Form 10-K for the year ended December ~~30, 2017.~~29, 2018. If any of the identified risks actually occur, our business, financial condition and results of operations could suffer. The trading price of our common stock could decline and you may lose all or part of your investment in our common stock. The risks and uncertainties described in our Annual Report on Form 10-K for the year ended December ~~30, 2017~~29, 2018 are not the only ones we face. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations.
