NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

     The interim unaudited consolidated financial statements included herein have been prepared by PDF Solutions, Inc., (the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) specifically instructions to Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. The unaudited interim consolidated financial statements reflect, in the opinion of management, all adjustments necessary, (consisting only of normal recurring adjustments) to present a fair statement of results for the interim periods presented. The operating results for any interim period are not necessarily indicative of the results that may be expected for other interim periods or the full fiscal year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2002.

     The preparation 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, liabilities, revenues and expenses. A significant portion of the Company’s revenues require estimates in regards to total costs which may be incurred and revenues earned. Actual results could differ from these estimates.

     The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries after the elimination of all significant intercompany balances and transactions. Certain amounts from prior years have been reclassified to conform to current-year presentation. These reclassifications did not change previously reported total assets, liabilities, stockholders’ equity or net income.

Stock Based Compensation

     The Company accounts for stock-based compensation in accordance with the provisions of Accounting Principles Board Opinion No. 25 “Accounting for Stock Issued to Employees” (“APB No. 25”), and complies with the disclosure provisions of Statement of Financial Accounting Standards No. 123 (“SFAS No. 123”) as amended by SFAS 148, “Accounting for Stock-Based Compensation — Transition and Disclosures”. Deferred compensation recognized under APB No. 25 is amortized to expense using the graded vesting method. The Company accounts for stock options and warrants issued to non-employees in accordance with the provisions of SFAS No. 123 and its related interpretations under the fair value based method.

-4-


Table of Contents

          The Company adopted the disclosure-only provisions of SFAS No. 123, and accordingly, no expense has been recognized for options granted to employees under the various stock plans. The Company amortizes deferred stock-based compensation on the graded vesting method over the vesting periods of the applicable stock purchase rights and stock options, generally four years. The graded vesting method provides for vesting of portions of the overall awards at interim dates and results in greater vesting in earlier years than the straight-line method. Had compensation expense been determined for employee awards based on the fair value at the grant date for the awards, consistent with the provisions of SFAS No. 123, the Company’s pro forma net income (loss) and pro forma net income (loss) per share would be as follows (in thousands, except per share data):

     During the first quarter of 2003, the Company recorded $227,000 in compensation expense for the fair value of options granted to two non-employees. The 45,000 common shares under the 2001 Stock Plan were granted at an exercise price of $7.59 per share, the fair market value per share on the grant date were fully vested at the date of grant and contained restrictions on when shares could be sold.

2. ACQUISITIONS

IDS Software Systems

     On September 24, 2003, the Company completed its acquisition of IDS Software Systems, Inc (“IDS”). IDS, a privately held company, developed and licensed yield management software applications and services dedicated to the semiconductor industry to enable customers to track, and identify areas for yield improvement. The acquisition of IDS will provide the Company’s customers with greater capabilities for managing product yield improvement through the use of the acquired technology and services. The aggregate purchase price was $51.0 million which included the issuance of cash of $23.0 million, the issuance of 2.0 million shares of PDF common stock valued at $25.0 million, the assumption of stock options valued at $1.7 million and acquisition costs of $1.3 million. The fair value of the Company’s common stock was determined based on the average closing price per share of the Company’s common stock over a 5-day period beginning two trading days before and ending two trading days after the amended terms of the acquisition were agreed to and announced (September 3, 2003). The fair values of the options assumed were calculated as of September 24, 2003, based on the Black-Scholes options pricing model. The acquisition was accounted for using the purchase method of accounting in accordance with Statement of Financial Accounting Standards (“SFAS”) No 141, Business Combinations, and accordingly the Company’s unaudited consolidated financial statements from September 24, 2003 include the impact of the acquisition.

            51,012  
 
           
 

     The acquisition was accounted for as a purchase transaction, and accordingly, the assets and liabilities of IDS were recorded at their estimated fair values at the date of the acquisition. With the exception of the goodwill and acquired in-process research and development (“IPR&D”), the identified intangible assets will be amortized on a straight-line basis over their estimated useful lives, with a weighted average life of approximately four years. The acquired IPR&D technology was immediately expensed because technological feasibility had not been established and no future alternative use exists. In assessing IDS’s IPR&D projects, the key characteristics of the products under development were considered as well as future prospects, the rate at which technology changes, product life cycles, and the projects’ stages of development. The IPR&D technology write-off is included as a component of operating expenses in the unaudited consolidated statement of operations. The fair value of IPR&D, as well as the fair value of the identifiable intangible assets, was determined, in part, by an independent third party appraiser through established valuation techniques.

     The acquisition of IDS was structured as a tax-free acquisition. Therefore, the difference between the recognized fair values of the acquired net assets and their historical tax basis are not deductible for tax purposes. A deferred tax liability has been recognized for the difference between the assigned fair values of intangible assets for book purposes and the tax basis of such assets.

     The following unaudited pro forma consolidated financial data represents the combined results of operations as if IDS had been combined with the Company at the beginning of the respective period. This pro forma financial data includes the straight line amortization of intangibles over their respective estimated useful lives and excludes the write-off of IPR&D (in thousands):

The unaudited pro forma consolidated financial information for the three and nine months ended September 30, 2003, have been restated to correct certain errors regarding the information used in such computations.

WaferYield

     On May 31, 2003 the Company acquired certain assets and liabilities of WaferYield, Inc., (“WaferYield”) a privately held company, which primarily included WaferYield’s proprietary shot map WAMA™ technology and related business. The WAMA product offering is designed to optimize semiconductor wafer shot maps to help semiconductor companies achieve greater yield and net die per wafer, higher stepper throughput and reduced probe test cost. This acquisition adds to the Company’s product offering and its capabilities in enabling semiconductor companies to improve yield and performance of ICs. The aggregate purchase price was $4.1 million, which included cash payments of $2.6 million and the recognition of $1.5 million in other liabilities associated with future payments that are contingent upon the attainment of certain revenue performance objectives. There were no other assets or liabilities assumed in connection with the acquisition. The agreement also contains additional payments in the event the Company achieves further performance objectives as specified in the agreement, up to an additional payment of $3.5 million. Any additional payments made as a result of achieving such operating levels, which exceed amounts currently accrued, will be accounted for as goodwill in relation to the purchase. The entire purchase price has been allocated to core technology which is being amortized over an estimated useful life of 4 years. The acquisition has been accounted for using the purchase method of accounting and accordingly, the Company’s consolidated financial statements from May 31, 2003 include the impact of the acquisition. Proforma results of operations have not been presented because the effect of the acquisition was not material to the Company.

3. RECENT ACCOUNTING PRONOUNCEMENTS

     In July 2002, the Financial Accounting Standards Board (“FASB”) issued Statements of Financial Accounting Standards (“SFAS”) No. 146, “Accounting for Costs Associated with Exit or Disposal Activities.” SFAS No. 146 addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies Emerging Issues Task Force (“EITF”) Issue No. 94-3, “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (Including Certain Costs Incurred in a Restructuring)” and must be applied beginning January 1, 2003. SFAS No. 146 requires that a liability for a cost associated with an exit or disposal activity be recognized when the liability is incurred rather than when the exit or disposal plan is approved. The Company adopted SFAS No. 146 on January 1, 2003. The adoption of this statement did not have an effect on the financial position and operating results of the Company.

     In November 2002, the FASB issued FASB Interpretation (“FIN”) No. 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others”. FIN 45 requires companies to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. Guarantees in existence at December 31, 2002 are grandfathered for the purposes of recognition and would only need to be disclosed. The Company adopted FIN 45 on January 1, 2003. The adoption of this statement did not have an effect on the Company’s financial position and operating results.

     The Company generally provides a warranty to its customers that its software will perform substantially in accordance with documentation typically for a period of 90 days following delivery of its products. The Company also indemnifies certain customers from third-party claims of intellectual property infringement relating to the use of its products. Historically, costs related to these guarantees have not been significant. The Company is unable to estimate the maximum potential impact of these guarantees on its future results of operations.

     In December 2002, the EITF reached a consensus on EITF 00-21, “Revenue Arrangements with Multiple Deliverables”. This issue addresses certain aspects of the accounting by a vendor for arrangements under which it will perform multiple revenue-generating activities. In some arrangements, the different revenue-generating activities (deliverables) are sufficiently separable and there exists sufficient evidence of their fair values to separately account for some or all of the deliverables (that is, there are separate units of accounting). In other arrangements, some or all of the deliverables are not independently functional, or there is not sufficient evidence of

-7-


Table of Contents

their fair values to account for them separately. This issue addresses when and, if so, how an arrangement involving multiple deliverables should be divided into separate units of accounting. This issue does not change otherwise applicable revenue recognition criteria. The guidance in this issue is effective for revenue arrangements entered into in fiscal periods beginning after June 15, 2003. The adoption of EITF 00-21 did not have an effect on the Company’s financial position and results of operations.

     In December 2002, the FASB issued SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure, an amendment to FASB Statement 123”. SFAS No. 148 provides alternative methods of transition for a voluntary change to the fair value based method of accounting of stock-based employee compensation. In addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123, “Accounting for Stock-Based Compensation”, to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The Company adopted the disclosure provisions of SFAS No. 148 effective December 31, 2002.

     In January 2003, the FASB issued Interpretation No. 46 (FIN 46), Consolidation of Variable Interest Entities. FIN 46 amended ARB 51, Consolidated Financial Statements, and established standards for determining under what circumstances a variable interest entity (VIE) should be consolidated with its primary beneficiary. FIN 46 also requires disclosures about VIE’s that the company is not required to consolidate, but in which it has a significant variable interest. We do not expect the adoption of FIN 46 will have a material effect on the Company’s financial position and results of operations.

4. ACCOUNTS RECEIVABLE

     Accounts receivable include amounts that are unbilled at the end of the period. Unbilled accounts receivable are determined on an individual contract basis and were approximately $1.3 million and $1.0 million at September 30, 2003 and December 31, 2002, respectively.

5. NET INCOME (LOSS) PER SHARE

     Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average common shares outstanding for the period (excluding shares subject to repurchase). Diluted net income (loss) per share reflects the weighted-average common shares outstanding plus the potential effect of dilutive securities which are convertible into common shares (using the treasury stock method), except in cases where the effect would be anti-dilutive. The following is a reconciliation of the numerators and denominators used in computing basic and diluted net income (loss) per share (in thousands):

                                   
      Three Months   Nine Months
      Ended September 30,   Ended September 30,

Table of Contents

     For the three month period ended September 30, 2002, the calculation of diluted net income per share does not include 250,000 outstanding common stock options as the effect would be anti-dilutive for the period presented. For the three and nine month periods ended September 30, 2003, the calculation of diluted net loss per share does not include, respectively 1.0 million and 590,000 outstanding common stock options and 392,000 and 579,000 shares of common stock subject to repurchase as the effect would be anti-dilutive for the periods presented.

6. COMPREHENSIVE INCOME (LOSS)

     The components of comprehensive income (loss) are as follows (in thousands):

                                 
    Three Months   Nine Months
    Ended September 30,   Ended September 30,

7. GOODWILL AND PURCHASED INTANGIBLE ASSETS

     On January 1, 2002, the Company adopted SFAS No. 142, Goodwill and Other Intangible Assets (“SFAS No. 142”). SFAS No. 142 requires goodwill to be tested for impairment under certain circumstances, written down when impaired, and requires purchased intangible assets other than goodwill to be amortized over their useful lives unless these lives are determined to be indefinite. Upon the adoption of SFAS No. 142 the Company ceased amortization of goodwill with a net book value totaling $662,000, which included $192,000 of acquired workforce intangibles, net of related deferred tax liabilities which were reclassified to goodwill pursuant to the requirements of SFAS No. 142.

     The following table provides information relating to the intangible assets and goodwill contained within the Company’s consolidated balance sheets as of September 30, 2003 and December 31, 2002 (in thousands):

     As required by SFAS No. 142, the Company performed its transitional impairment test of goodwill as of January 1, 2002, at which time the Company determined that the carrying value of goodwill had not been impaired. SFAS No. 142 also requires that goodwill be tested for impairment on an annual basis and more frequently in certain circumstances. Accordingly, the Company has selected the three-month period ending December 31, to perform the annual testing requirements. During the three-month period ending December 31, 2002, the Company completed its annual testing requirements and determined that the carrying value of goodwill had not been impaired.
