1. Summary of Significant Accounting Principles

Basis of Presentation

     The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In management’s opinion, the accompanying financial statements reflect all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the results for the interim periods presented.

     Interim financial results are not necessarily indicative of results anticipated for the full year. These unaudited financial statements should be read in conjunction with the Company’s 2003 audited financial statements and footnotes included in the Company’s Annual Report on Form 10-K.

     The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of expenses incurred during the reporting period. Actual results could differ from those estimates.

Fiscal Year

     The Company’s fiscal year is 52 or 53 weeks ending the Sunday closest to December 31, with quarters of 13 or 14 weeks ending the Sunday closest to March 31, June 30, and September 30.

Revenue Recognition

     The Company records revenue in accordance with the guidelines established by SEC Staff Accounting Bulletin No. 101 (“SAB 101”). Under SAB 101, revenue cannot be recorded until all the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the seller’s price to the buyer is fixed or determinable; and collectibility is reasonably assured. Product revenue consists of sales of oligonucleotides, arrays, assay reagents, genotyping systems and gene expression systems. Service revenue consists of revenue received for performing SNP genotyping services. Revenue for product sales is recognized generally upon shipment and transfer of title to the customer, provided no significant obligations remain and collection of the receivables is reasonably assured. BeadLab genotyping system revenue is recognized when earned, which is generally upon shipment, installation, training and fulfillment of contractually defined acceptance criteria. Reserves are provided for anticipated product warranty expenses at the time the associated revenue is recognized. Revenue for genotyping services is recognized generally at the time the genotyping analysis data is delivered to the customer. The Company has been awarded $9.1 million from the National Institutes of Health to perform genotyping services in connection with the International HapMap Project. A portion of the revenue from this project is earned at the time the related costs are incurred while the remainder of the revenue is earned upon the delivery of genotyping data. Research revenue consists of amounts earned under research agreements with government grants, which is recognized in the period during which the related costs are incurred. All revenues are recognized net of applicable allowances for returns or discounts.

     The Company received $10.0 million of non-refundable research funding from Applied Biosystems in connection with a licensing and development contract entered into in 1999. This amount was originally recorded as deferred revenue in accordance with the provisions of SAB 101 and would have been recognized as revenue at a contractually defined rate of 25% of the defined operating profit earned from sales of the products covered by the

collaboration agreement, had such sales occurred. The Company does not believe a collaboration product will be commercialized under the partnership agreement, and there are legal proceedings between the parties as more fully described in Note 6. The $10.0 million of research funding has been reclassified to an advance payment from former collaborator until the legal proceedings have been resolved.

Cash & Investments

     Cash and cash equivalents are comprised of highly liquid investments with a remaining maturity of less than three months from the date of purchase.

     The Company applies Statement of Financial Accounting Standards (“SFAS”) No. 115, Accounting for Certain Investments in Debt and Equity Securities, to its investments. Under SFAS No. 115, the Company classifies its investments as “Available-for-Sale” and records such assets at estimated fair value in the balance sheet, with unrealized gains and losses, if any, reported in stockholders’ equity. The cost of securities sold is determined based on the specific identification method. The Company invests its excess cash balances in marketable debt securities, primarily government securities and corporate bonds and notes, with strong credit ratings or short maturity mutual funds providing similar financial returns. The Company limits the amount of investment exposure as to institutions, maturity and investment type.

     Restricted cash and investments consist of corporate debt securities that are used as collateral against a letter of credit (see Note 7) and $100,000 in a money market fund for a bond deposit with the San Diego Superior Court related to the Applied Biosystems litigation (see Note 6).

Stock-Based Compensation

     At June 27, 2004, the Company had three stock-based employee and non-employee director compensation plans, which are described more fully in the Company’s 2003 Annual Report on Form 10-K. As permitted by SFAS No. 123, Accounting for Stock-Based Compensation, the Company accounts for common stock options granted, and restricted stock sold, to employees, founders and directors using the intrinsic value method and, thus, recognizes no compensation expense for options granted, or restricted stock sold, with exercise prices equal to or greater than the fair value of the Company’s common stock on the date of the grant. The Company has recorded deferred stock compensation related to certain stock options, and restricted stock, which were granted prior to the Company’s initial public offering with exercise prices below estimated fair value, which is being amortized on an accelerated amortization methodology in accordance with Financial Accounting Standards Board Interpretation Number (“FIN”) 28.

     Pro forma information regarding net loss is required by SFAS No. 123 and has been determined as if the Company had accounted for its employee stock options and employee stock purchases under the fair value method of that statement. The fair value for these options was estimated at the dates of grant using the fair value option pricing model (Black Scholes) with the following weighted-average assumptions:

     For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the vesting period. The Company’s pro forma information is as follows (in thousands except per share amounts):

                                 
    Three months ended

Add: Stock-based compensation expense recorded
    250       684       568       1,549  
Less: Assumed stock compensation expense
    (2,313 )     (2,129 )     (4,653 )     (4,283 )
 
   
 
     
 
     
 
     
 
 
Pro forma net loss
  $ (5,579 )   $ (10,037 )   $ (11,532 )   $ (20,286 )
 
   
 
     
 
     
 
     
 
 
Basic and diluted net loss per share:
                               
As reported
  $ (0.10 )   $ (0.27 )   $ (0.22 )   $ (0.55 )
 
   
 
     
 
     
 
     
 
 
Pro forma
  $ (0.16 )   $ (0.32 )   $ (0.34 )   $ (0.64 )
 
   
 
     
 
     
 
     
 
 

     The pro forma effect on net loss presented is not likely to be representative of the pro forma effects on reported net income or loss in future years because these amounts reflect less than five years of vesting.

     Deferred compensation for options granted, and restricted stock sold, to consultants has been determined in accordance with SFAS No. 123 and Emerging Issues Task Force 96-18 as the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measured. Deferred charges for options granted, and restricted stock sold, to consultants are periodically remeasured as the underlying options vest.

Net Loss per Share

     Basic and diluted net loss per common share are presented in conformity with SFAS No. 128, Earnings per Share for all periods presented. In accordance with SFAS No. 128, basic and diluted net loss per share is computed using the weighted-average number of shares of common stock outstanding during the period, less shares subject to repurchase. Diluted net loss per share is typically computed using the weighted average number of common and dilutive common equivalent shares from stock options using the treasury stock method. However, for all periods presented, diluted net loss per share is the same as basic net loss per share because the Company reported a net loss and therefore the inclusion of weighted average shares of common stock issuable upon the exercise of stock options would be antidilutive.

Comprehensive Income (Loss)
                               

     SFAS No. 130, Comprehensive Income, establishes rules for the reporting and disclosure of comprehensive income and its components. SFAS No. 130 requires the change in net unrealized gains or losses on marketable securities to be included in comprehensive income. As adjusted, our comprehensive loss is as follows (in thousands):

2. Segment Information

     The Company has determined that, in accordance with SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information, it operates in one segment as it only reports operating results on an aggregate basis to chief operating decision makers of the Company.

3. Inventories

     Inventories are stated at the lower of standard cost (which approximates actual cost) or market. Inventory includes raw materials and finished goods that may be used in the research and development process and such items are expensed as consumed. The components of net inventories are as follows:

4. Warranties

     The Company generally provides a one year warranty on genotyping systems. At the time revenue is recognized, the Company establishes an accrual for estimated warranty expenses associated with genotyping system sales. This expense is recorded as a component of cost of revenue.

     Changes in the Company’s warranty liability during the six months ended June 27, 2004 are as follows (in thousands):

5. Commitments and Long-Term Debt

     In July 2000, the Company entered into a 10-year lease to rent space in two newly constructed buildings that are now occupied by the Company. That lease contained an option to purchase the buildings together with certain adjacent land that has been approved for construction of an additional building. The Company exercised that option and purchased the properties in January 2002 and assumed a $26 million, 10-year mortgage on the property at a fixed interest rate of 8.36%. The Company is required to make monthly payments of $208,974 representing interest and principal through February 2012, at which time a balloon payment of $21.2 million will be due. On June 18, 2004, the Company entered into a conditional agreement to sell its land and buildings for $42.0 million and to lease back such property for an initial term of ten years. The sale is subject to certain closing conditions, including

the closing of the initial public offering of common stock of the buyer. There can be no assurances that these conditions will be satisfied in a timely manner or at all.

     The Company leases office space under non-cancelable operating leases that expire at various times through December 2006. These leases contain renewal options ranging from 2 to 3 years.

6. Collaborative Agreements

Applied Biosystems Group (part of Applera Corporation)

     In November 1999, the Company entered into a joint development agreement with Applied Biosystems Group (“Applied Biosystems”) under which the companies would jointly develop a SNP genotyping system that would combine the Company’s BeadArray technology with Applied Biosystems’ assay chemistry and scanner technology. Under this agreement, the Company was primarily responsible for developing and manufacturing the arrays and Applied Biosystems was primarily responsible for developing and manufacturing the instruments, SNP assay reagents, and software and for marketing the system worldwide. In conjunction with the agreement, Applied Biosystems purchased 1,250,000 shares of the Company’s Series C convertible preferred stock at $4.00 per share. In addition, Applied Biosystems agreed to provide the Company with non-refundable research and development support of $10.0 million, all of which was provided by December 2001. Upon commercialization of the system, the Company would have received a share of the operating profits resulting from the sale of all components of these systems. The Company had originally deferred recognition of revenue from the research funding of $10.0 million provided by Applied Biosystems, and would have recognized such amounts as revenue at a contractually defined rate of 25% of the total profit share the Company earned from the sales of collaboration products, had such sales occurred. As of December 28, 2003 this amount was reclassified to an advance payment from former collaborator.

     In July 2002, Applied Biosystems indicated that the planned mid-2002 launch of this genotyping system would be delayed a second time. This delay was related to Applied Biosystems’ inability to optimize and multiplex the SNP assay reagents. The Company does not believe that Applied Biosystems has any intention of continuing to develop a collaboration product with the Company, and Applied Biosystems has launched a competing product. As a result of the delay in developing the collaboration product, the Company launched its own production scale genotyping system in July 2002 utilizing the Company’s arrays and an independently developed scanner and assay method.

     In December 2002, Applied Biosystems filed a complaint, and later amended and refiled a complaint in March 2003, for a patent infringement suit against the Company in the federal court in Northern California asserting infringement of several patents related to Applied Biosystems’ patented assay intended for use in the collaboration. Applied Biosystems seeks a judgment granting it damages for infringement, treble damages alleging that such infringement is willful and a permanent injunction restraining the Company from the alleged infringement. The Company has answered the complaint, asserting various defenses, including that it does not infringe the patents or that the patents are invalid, and asserting counterclaims against Applied Biosystems seeking declaratory judgment relief related to the patents being asserted against it, and seeking damages from Applied Biosystems for its alleged unfair and unlawful conduct which constitutes attempted monopolization in violation of the antitrust laws. This action is currently stayed pending the outcome of an arbitration proceeding between the parties.

     Also in December 2002, Applied Biosystems sent a notification to the Company alleging that the Company had breached the joint development agreement entered into in November 1999 and seeking to compel arbitration pursuant to that agreement. This notification alleged that the Company’s production-scale genotyping products and services are collaboration products developed under the joint development agreement, and that the Company’s commercial activities with respect to its genotyping products and services are unlawful, unfair or fraudulent. Among other relief, Applied Biosystems is seeking compensatory damages of $30 million, disgorgement of all revenues received from sales of these products and services and a prohibition of future sales of these products or services.

     In December 2002, the Company filed a suit alleging breach of contract, breach of the implied covenant of good faith and fair dealing, unfair competition and other allegations against Applied Biosystems in San Diego Superior Court, and a motion for a temporary restraining order to prevent the arbitration of the joint development agreement sought by Applied Biosystems. In January 2004, the Company notified Applied Biosystems that it was terminating the joint development agreement.

     In December 2003, after having granted temporary and preliminary injunctions staying the arbitration, the San Diego Superior Court directed Applied Biosystems and the Company to resolve the contract dispute in a binding arbitration procedure. After the Superior Court ordered the parties to the arbitration process, Applied Biosystems purported to amend its demands for arbitration to add new allegations against the Company (including claims of malicious prosecution, abuse of process, fraud in the inducement, interference with a prospective economic advantage, declaratory judgment that the joint development agreement had not been terminated and a new claim of breach of contract based on alleged poor quality of the Company’s arrays) and to increase its demand for cash damages to an unspecified amount in excess of $60 million. An arbitrator has been selected, and the arbitration hearing is currently scheduled to be completed in December 2004, with a written decision from the arbitrator expected in early 2005.

     The Company will vigorously defend against the claims alleged by Applied Biosystems but the outcome of an arbitration proceeding is inherently uncertain and the Company cannot be sure that it will prevail. This arbitration could result in a range of potential outcomes, based solely on the judgment and discretion of the arbitrator, including (1) the award of all damages and injunctive relief sought by Applied Biosystems; (2) the award of all damages and relief sought by the Company; or (3) a partial award of damages and/or injunctive relief to either party. The Company has not accrued for any potential losses in this case because it believes that an adverse determination is not probable, and potential losses cannot be reasonably estimated. However, the Company’s financial statements include a $10.0 million advance payment from Applied Biosystems that would have been deducted from the profits otherwise payable to the Company from Applied Biosystems had the collaboration been successful and which could offset the impact on the Company’s consolidated results of operations of an adverse arbitration determination up to that amount. Any unfavorable arbitration determination, and in particular any significant cash amounts required to be paid by the Company or prohibition of the sale of its products or services, could result in a material adverse effect on the Company’s business, financial condition and results of operations.

     The Company is in the early stages of proceedings in the patent case brought by Applied Biosystems. In February 2004, the federal district court in Northern California ordered that the patent case be stayed pending completion of the arbitration process. The Company intends to vigorously defend against the claims alleged by Applied Biosystems and continue to pursue its counterclaims against Applied Biosystems. However, the Company cannot be sure that it will prevail in these matters. Any unfavorable determination, and in particular any significant cash amounts required to be paid by the Company or prohibition of the sale of the Company’s products or services, could result in a material adverse effect on its business, financial condition and results of operations.

Other Agreements

     The Company is the recipient of a grant from the National Institutes of Health covering its participation in the International HapMap Project, which is a $100.0 million, internationally funded successor project to the Human Genome Project that will help identify a map of genetic variations that may be used to perform disease-related research. The Company could receive up to $9.1 million of funding for this project which covers basic research activities, the development of SNP assays and the genotyping to be performed on those assays. As of June 27, 2004, the Company had approximately $3.8 million of funding remaining related to this project which is expected to be received in fiscal 2004 and 2005, depending on the actual amount of work that is performed by the Company.

7. Litigation Judgment

Notes to Condensed Consolidated Financial Statements (continued)
(Unaudited)

     In June 2002, the Company recorded a $7.7 million charge to cover total damages and estimated expenses awarded by a jury related to a termination-of-employment lawsuit. The Company believes that the termination was lawful in all respects and that the verdict was unsupported by evidence presented at the trial. The Company plans to vigorously defend its position on appeal. A notice of appeal in this case was filed on October 10, 2002, and the appeal process is ongoing. During the appeal process, the court requires the Company to incur interest charges on the judgment amount at statutory rates until the case is resolved. For each of the three and six months ended June 27, 2004 and June 29, 2003, the Company recorded litigation expense of $189,000 and $378,000 for interest.

     As a result of the Company’s decision to appeal the ruling, the Company filed a surety bond with the court equal to 1.5 times the judgment amount or approximately $11.3 million. Under the terms of the bond, the Company is required to maintain a letter of credit for 90% of the bond amount to secure the bond. Further, the Company was required to deposit approximately $12.5 million of marketable securities as collateral for the letter of credit and accordingly, these funds will be restricted from use for general corporate purposes until the appeal process is completed. An oral argument before the appeals court is expected to occur in the third quarter of 2004, and if a judgment is due, the Company expects payment will occur within 12 months.

8. Subsequent Events

     In July 2004, Affymetrix, Inc. (“Affymetrix”) filed a complaint in the U.S. District Court for the District of Delaware alleging that certain of the Company’s products infringe six Affymetrix patents. The suit seeks an unspecified amount of monetary damages and a judgment enjoining the sale of products, if any, that are determined to be infringing these patents. The Company has not yet responded to this complaint but believes it has meritorious defenses against each of the patents alleged by Affymetrix and intends to vigorously defend itself against this suit. However, the Company cannot be sure it will prevail in this matter. Any unfavorable determination, and in particular, any significant cash amounts required to be paid by the Company or prohibition of the sale of the Company’s products and services, could result in a material adverse effect on its business, financial condition and results of operations.

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

     This discussion and analysis should be read in conjunction with our financial statements and accompanying notes included in this report and the financial statements and notes thereto for the year ended December 28, 2003 included in the Company’s Annual Report on Form 10-K. Operating results are not necessarily indicative of results that may occur in future periods.

     The following discussion and analysis may contain forward-looking statements that involve risk and uncertainties, such as statements of our plans, objectives, expectations and intentions. The cautionary statements made in this discussion and analysis should be read as applying to all related forward-looking statements wherever they appear in this Quarterly Report on Form 10-Q. Our actual results could differ materially from those discussed here. Factors that could cause or contribute to these differences include those discussed in “Factors Affecting Operating Results” below as well as those discussed elsewhere.

Overview

     Illumina, Inc. was incorporated in April 1998. We are developing next-generation tools for the large-scale analysis of genetic variation and function. Understanding genetic variation and function is critical to the development of personalized medicine, a key goal of genomics. Using our technologies, we have developed a comprehensive line of products that are designed to provide the throughput, cost effectiveness and flexibility necessary to enable researchers in the life sciences and pharmaceutical industries to perform the billions of tests necessary to extract medically valuable information from advances in genomics. This information is expected to correlate genetic variation and gene function with particular disease states, enhancing drug discovery, allowing diseases to be detected earlier and more specifically, and permitting better choices of drugs for individual patients.

     In November 1999, we entered into a joint development agreement with Applied Biosystems under which the companies would jointly develop a SNP genotyping system that would combine our BeadArray technology with Applied Biosystems’ assay chemistry and scanner technology. Under this agreement, we were primarily responsible for developing and manufacturing the arrays and Applied Biosystems was primarily responsible for developing and manufacturing the instruments, SNP assay reagents, and software and for marketing the system worldwide. In conjunction with the agreement, Applied Biosystems purchased 1.25 million shares of our Series C convertible preferred stock at $4.00 per share. In addition, Applied Biosystems agreed to provide us with non-refundable research and development support of $10.0 million, all of which was provided by December 2001. Upon commercialization of the system, we would have received a share of the operating profits from the sales of all components of these systems. We had originally deferred recognition of revenue from the research funding of $10.0 million provided by Applied Biosystems, and would have recognized such amounts as revenue at a contractually defined rate of 25% of the total profit share we earned from the sales of collaboration products, had such sales occurred. As of December 28, 2003, this amount was reclassified to an advance payment from former collaborator.

     In July 2002, Applied Biosystems indicated that the planned mid-2002 launch of this genotyping system would be delayed a second time. This delay was related to Applied Biosystems’ inability to optimize and multiplex the SNP assay reagents. We do not believe that Applied Biosystems has any intention of continuing to develop a collaboration product with us, and it has launched a competing product. As a result of the delay in developing the collaboration product, we launched our own production-scale genotyping system in July 2002 utilizing our arrays and an independently developed scanner and assay method.

the complaint, asserting various defenses, including that we do not infringe the patents or that the patents are invalid, and asserting counterclaims against Applied Biosystems seeking declaratory judgment relief related to the patents being asserted against us, and seeking damages from Applied Biosystems for its alleged unfair and unlawful conduct which constitutes attempted monopolization in violation of the antitrust laws. This action is currently stayed pending the outcome of an arbitration proceeding between the parties.

An arbitrator has been selected, and the arbitration hearing is currently scheduled to be completed in December 2004, with a written decision from the arbitrator expected in early 2005.

However, our financial statements include a $10.0 million advance payment from Applied Biosystems that would have been deducted from the profits otherwise payable to us from Applied Biosystems had the collaboration been successful and which could offset the impact on our consolidated results of operations of an adverse arbitration determination up to that amount. Any unfavorable arbitration determination, and in particular any significant cash amounts required to be paid by us or prohibition of the sale of our products or services, could result in a material adverse effect on our business, financial condition and results of operations.

     We are in the early stages of proceedings in the patent case brought by Applied Biosystems.

     In July 2004, Affymetrix filed a complaint in the U.S. District Court for the District of Delaware alleging that certain of our products infringe six Affymetrix patents. The suit seeks an unspecified amount of monetary damages and a judgment enjoining the sale of products, if any, that are determined to be infringing these patents. We have not yet responded to this complaint but believe we have meritorious defenses against each of the patents alleged by Affymetrix and intend to vigorously defend ourselves against this suit. However, we cannot be sure we will prevail in this matter. Any unfavorable determination, and in particular, any significant cash amounts required to be paid by us or prohibition of the sale of our products and services, could result in a material adverse effect on our business, financial condition and results of operations.

     We expect to devote substantial financial and managerial resources to protect our intellectual property rights and to defend against the claims described above as well as any future claims asserted against us.

     In the first quarter of 2001, we began commercial sale of short pieces of DNA, or oligos, manufactured using our proprietary Oligator technology. We believe our Oligator technology is more cost effective than competing technologies, which has allowed us to market our oligonucleotides under a price leadership strategy while still achieving attractive gross margins. In the second quarter of 2001, we initiated our SNP genotyping services product line. As a result of the increasing market acceptance of our high throughput, low cost BeadArray technology, we have entered into genotyping services contracts with many of the leading genotyping organizations, including GlaxoSmithKline and The Sanger Centre, and have been awarded $9.1 million from the National Institutes of Health to play a major role in the International HapMap Project.

     Our production-scale genotyping system, BeadLab, is based on the system we developed that has been operational in our genotyping service product line since 2001. In addition to our Sentrix Array Matrices, it includes the BeadArray Reader, a proprietary scanner that uses a laser to read the results of experiments captured on our arrays, as well as the GoldenGate SNP genotyping assay which can analyze up to 1536 SNPs per DNA sample. This system is being marketed to a small number of high throughput genotyping users.

     In 2003, we completed the installation of and recorded revenue for six BeadLab high-throughput SNP genotyping systems. In the six months ended June 27, 2004, we installed and recorded revenue for two additional BeadLab systems and signed an agreement to sell one additional BeadLab system.

     In 2003, we announced the launch of several new products, including 1) a new array format, the Sentrix BeadChip, which is expected to significantly expand market opportunities for our BeadArray technology and provide increased experimental flexibility for life science researchers;. 2) a gene expression product line on both the Sentrix Array Matrix and the Sentrix BeadChip that allows researchers to analyze a focused set of genes across eight to 96 samples on a single array; and 3) a benchtop SNP genotyping and gene expression system, the BeadStation, for performing moderate scale genotyping and gene expression using our technology. The BeadStation includes our BeadArray Reader, analysis software and assay reagents and is designed to match the throughput requirements and variable automation needs of individual research groups and core labs. Sales of these products began in the first quarter of 2004 and as of June 27, 2004, we have sold 15 BeadStations.

     In 2004, we announced the launch of new Sentrix BeadChips for whole-genome gene expression and whole-genome genotyping. The whole-genome gene expression BeadChips are designed to enable high-performance, cost-effective, whole-genome expression profiling of multiple samples on a single chip, resulting in a dramatic reduction in cost of whole-genome expression analysis while allowing researchers to expand the scale and reproducibility of large-scale biological experimentation. The whole-genome genotyping BeadChip can be scaled to unlimited levels of multiplexing without compromising data quality and will provide scientists the ability to query, in parallel, a high-value set of over 100,000 SNPs. In 2004, we also announced two new lower complexity Sentrix arrays designed for researchers who want to take advantage of our technology, but whose projects require fewer SNPs per sample than the number utilized on our standard 1536-plex array products.

     We are seeking to expand our customer base for our BeadArray technology; however, we can give no assurance that our sales efforts will continue to be successful.

     A significant portion of our revenue is derived from a few, large individual transactions such as the sale of BeadLab production genotyping systems and large genotyping services contracts, including our work on the

15

Condition and Results of Operations (continued)

International HapMap Project. Because these transactions may not occur regularly and there is a lengthy sales cycle for such transactions, revenue of these types may not occur on a consistent or frequent basis. In addition, our total amount of revenues is subject to fluctuations in demand from seasonality impacts, the timing and amount of government grant funding programs, the timing and size of research projects our customers perform and changes in overall spending levels in the life science industry. Given the difficulty in predicting the timing and magnitude of sales for our products, we may experience quarter-to-quarter fluctuations in revenue, resulting in the potential for a sequential decline in quarterly revenue. Due to the possibility of fluctuations in our revenue and net income or loss, we believe quarterly comparisons of our operating results are not a good indication of our future performance.

     We have incurred substantial operating losses since our inception. As of June 27, 2004, our accumulated deficit was $124.9 million, and total stockholders’ equity was $69.7 million. These losses have principally occurred as a result of the substantial resources required for the research, development and manufacturing scale up effort required to commercialize our products and services, as well as charges of $9.2 million related to a termination-of-employment lawsuit. We expect to continue to incur substantial costs for research, development and manufacturing scale up activities over the next several years. We will also need to significantly increase our selling, general and administrative costs as we build up our sales and marketing infrastructure to expand and support the sale of systems, other products and services. As a result, we will need to increase revenue significantly to achieve profitability.

     Revenue for the three and six months ended June 27, 2004 was $11.5 million and $22.3 million, respectively, increasing $6.7 million from $4.8 million in the three month period ended June 27, 2004 and increasing $13.2 million from $9.1 million in the six month period ended June 27, 2004.

     Product revenue increased to $9.1 million and $18.0 million, respectively, for the three and six months ended June 27, 2004 from $2.7 million and $4.1 million, respectively, for the three and six months ended June 29, 2003. The increase in the second quarter of 2004 resulted almost entirely from sales of consumables used on our BeadLab systems and sales of our BeadStation benchtop genotyping systems. In 2003, we had no sales of BeadStation genotyping systems and we only began selling consumable products in May 2003. The increase for the six month period ending June 27, 2004 was primarily due to higher sales of BeadStation systems and consumables while oligo sales doubled over the prior period.

     SNP genotyping service revenue increased to $1.8 million from $1.5 million for the three months ended June 27, 2004 and June 29, 2003, respectively, primarily due to increased revenue related to the International HapMap Project in the second quarter of 2004. SNP genotyping service revenue decreased to $3.0 million from $3.3 million for the six months ended June 27, 2004 and June 29, 2003, respectively, due primarily to a lower level of third party services contracts completed during the 2004 period.

     Government grants and other research funding remained flat at $0.6 million for both the three months ended June 27, 2004 and June 29, 2003 and decreased to $1.3 million from $1.6 million for the six months ended June 27, 2004 and June 29, 2003, respectively, primarily due to a decrease in internal research spending for our grant from the National Institutes of Health covering our participation in the International HapMap Project.

     We have recently begun shipment of our BeadStation system for moderate throughput genotyping needs, and have announced two multi-sample whole genome gene expression BeadChips that can be read on both BeadStations and BeadLabs. Our BeadLab systems address a limited number of potential high throughput genotyping customers, and sales of these systems may decline in 2004 versus 2003. We expect the sales of the new products mentioned above to offset such decline and for overall revenues to increase above 2003 levels.

Gross margins on product and service revenues were 72% for both the three and six months ended June 27, 2004, compared to 52% and 47%, respectively, for the three and six months ended June 29, 2003. This increase is due primarily to increased sales of higher margin consumable products, as well as efficiencies gained in oligo manufacturing and SNP genotyping services. We expect the increased amount of consumable sales in our 2004 product mix, as compared to our 2003 product mix, will continue to favorably affect our gross margins as compared with 2003. However, we expect our market will become increasingly price competitive, and over the longer term, our margins may decline.

     Our research and development expenses consist primarily of salaries and other personnel-related expenses, laboratory supplies and other expenses related to the design, development, testing and enhancement of our products. We expense our research and development costs as they are incurred. Research and development expenses decreased to $5.3 million and $10.5 million, respectively, for the three and six months ended June 27, 2004 from $6.2 million and $11.9 million, respectively, for the three and six months ended June 29, 2003.

     During the three and six months ended June 27, 2004, the cost of BeadArray research activities decreased $0.4 million and $0.9 million, respectively, as compared to the three and six months ended June 29, 2003. The decrease occurred primarily as a result of completing the development of new products launched in 2003: the BeadChip, an additional microarray platform, a gene expression application on both our Array Matrix and BeadChip platforms and a benchtop SNP genotyping system, the BeadStation. Research to support our Oligator technology platform decreased $0.5 million in both the three and six months ended June 27, 2004 compared to the three and six months ended June 29, 2003. In the second quarter of 2003, we implemented additional Oligator manufacturing and software enhancements to expand capacity, increase throughput, and further reduce operating costs. In addition, as we increase our product sales, a smaller portion of our manufacturing resources are now used to support research efforts as compared to the same periods in 2003. We expect that our research and development expenses will remain relatively flat over the next 12 months.

     Stock based compensation related to research and development employees and consultants was $0.1 million and $0.2 million for the three and six months ended June 27, 2004 as compared to $0.4 million and $0.9 million for the three and six months ended June 29, 2003.

29, 2003. Approximately $1.1 million of the increase is due to higher sales and marketing costs, of which $0.8 million is attributable to personnel related expenses and $0.2 million is attributable to an increase in facility related expenses. Approximately $0.7 million of the increase in selling, general and administrative expenses is related to general and administrative costs. Legal expenses increased $0.5 million in the three months ended June 27, 2004 as compared to the three months ended June 29, 2003, and the majority of the remaining $0.2 million is attributable to expenses associated with our international expansion.

     Selling, general and administrative expenses increased $3.0 million to $11.7 million for the six months ended June 27, 2004 from $8.7 million for the six months ended June 29, 2003. Approximately $2.1 million of the increase is due to higher sales and marketing costs, of which $1.6 million is attributable to personnel related expenses and $0.3 million is attributable to an increase in facility related expenses. Approximately $0.8 million of the increase in selling, general and administrative expenses is related to general and administrative costs. Legal expenses increased $0.5 million in the six months ended June 27, 2004 as compared to the six months ended June 29, 2003, and the majority of the remaining $0.3 million is attributable to expenses associated with our international expansion. We expect that our selling, general and administrative expenses will accelerate as we expand our staff, add sales and marketing infrastructure and incur additional costs to support the commercialization and support of an increasing number of products.

     Stock based compensation related to selling, general and administrative employees, directors and consultants was $0.1 million and $0.3 million for the three and six months ended June 27, 2004 as compared to $0.3 million and $0.7 million for the three and six months ended June 29, 2003.

     From our inception through July 27, 2000, in connection with the grant of certain stock options and sales of restricted stock to employees, founders and directors, we have recorded deferred stock compensation totaling $17.7 million, representing the difference between the exercise or purchase price and the fair value of our common stock as estimated for financial reporting purposes on the date such stock options were granted or such restricted stock was sold. We recorded this amount as a component of stockholders’ equity and amortize the amount as a charge to operations over the vesting period of the restricted stock and options.

     We recognize compensation expense over the vesting period for employees, founders and directors, using an accelerated amortization methodology in accordance with Financial Accounting Standards Board Interpretation No. 28. For consultants, deferred compensation is recorded at the fair value for the options granted or stock sold in accordance with Statement of Financial Accounting Standards No. 123 and is periodically re-measured and expensed in accordance with Emerging Issues Task Force No. 96-18.

     We recorded amortization of deferred compensation of $0.3 million and $0.6 million, respectively, for the three and six months ended June 27, 2004 and $0.7 million and $1.5 million, respectively, for the three and six months ended June 29, 2003. We expect amortization of deferred compensation to continue to decrease due to the nature of the accelerated depreciation methodology as the options near the end of their vesting period.

     A $7.7 million charge was recorded in June 2002 to cover total damages and estimated expenses related to a termination-of-employment lawsuit. We believe that the termination was lawful in all respects and that the verdict was unsupported by evidence presented at the trial. We plan to vigorously defend our position on appeal. A notice of appeal in this case was filed on October 10, 2002, and the appeal process is ongoing. During the appeal process, the court requires us to incur interest charges on the judgment amount at statutory rates until the case is resolved. For both the three and six months ended June 27, 2004 and June 29, 2003, the Company recorded litigation expense of $189,000 and $378,000, respectively, for interest.

     Interest income on our cash and cash equivalents and investments was approximately $0.4 million and $0.5 million, respectively, for the three and six months ended June 27, 2004 as compared to $0.4 million and $1.0 million, respectively, for the three and six months ended June 29, 2003. The decrease is due to lower average levels of invested funds and lower effective interest rates, offset by realized gains in the second quarter of 2004. Interest expense was $0.6 million and $1.2 million, respectively, for the three and six months ended June 27, 2004 and $0.5 million and $1.1 million, respectively, for the three and six months ended June 29, 2003. Interest expense relates primarily to a $26.0 million fixed rate loan related to the purchase of our new facility during the first quarter of 2002.

Liquidity and Capital Resources

     As of June 27, 2004, we had cash, cash equivalents and investments (including restricted cash and investments of $12.1 million) of approximately $66.2 million. We currently invest our funds in U.S. dollar based investment-grade corporate and government debt securities, with strong credit ratings or short maturity mutual funds providing similar financial returns.

     Our operating activities used cash of $5.9 million in the six months ended June 27, 2004, as compared to $12.1 million in the six months ended June 29, 2003. Net cash used in operating activities in the six months ended June 27, 2004 was primarily the result of a net loss from operations of $7.5 million and a $5.4 million increase in accounts receivable reduced by a $3.8 million increase in accounts payable, accrued liabilities and other liabilities and non-cash charges of $2.2 million for depreciation and amortization. Net cash used in operating activities in the six months ended June 29, 2003 was primarily the result of a net loss from operations of $17.6 million reduced by non-cash charges of $2.3 million for depreciation and amortization, non-cash charges of $1.5 million for amortization of deferred stock compensation, a $0.6 million decrease in accounts receivable and a $0.6 million increase in accounts payable, accrued liabilities and other liabilities.

     Our investing activities provided cash of $18.3 million in the six months ended June 27, 2004 as compared to $16.5 million in the six months ended June 29, 2003. Cash provided in investing activities in the six months

ended June 27, 2004 and June 29, 2003 was due primarily to the sale or maturity of investment securities net of purchases of investment securities used to provide operating funds for our business.

     Our financing activities provided $29.0 million in the six months ended June 27, 2004 as compared to approximately $47,000 in the six months ended June 29, 2003. Cash provided in financing activities in the six months ended June 27, 2004 and June 29, 2003 was due primarily to proceeds from the issuance of common stock, including $28.7 million of net proceeds from the sale of approximately 4.6 million shares of our common stock in May 2004.

     In June 2002, we recorded a $7.7 million charge to cover total damages and estimated expenses related to a termination-of-employment lawsuit. As a result of our decision to appeal the ruling, we filed a surety bond with the court on October 25, 2002 of 1.5 times the judgment amount, or approximately $11.3 million. Under the terms of the bond, we are required to maintain a letter of credit for 90% of the bond amount to secure the bond. Further, we were required to deposit approximately $12.5 million of marketable securities as collateral for the letter of credit and accordingly, these funds will be restricted from use for corporate purposes until the appeal process is completed. If a judgment is due, we expect payment will occur within 12 months.

     As of June 27, 2004, we had funding remaining under existing NIH grants of approximately $4.7 million, including $3.8 million available under the International HapMap Project. All of these amounts are expected to be paid in 2004 and 2005, subject to the actual amount of activities we perform under these grants.

     Based on our current operating plans, we expect that our current cash and cash equivalents, investments, revenues from sales and funding from grants will be sufficient to fund our anticipated operating needs for at least 24 months. Operating needs include the planned costs to operate our business including amounts required to fund working capital and capital expenditures. At the current time, we have no material commitments for capital expenditures. However, our future capital requirements and the adequacy of our available funds will depend on many factors, including our ability to successfully commercialize our SNP genotyping and gene expression systems and extensions to those products and to expand our oligonucleotide and SNP genotyping services product lines, scientific progress in our research and development programs, the magnitude of those programs, competing technological and market developments, the successful resolution of our legal proceedings with Applied Biosystems, the successful resolution of our appeal in a termination-of-employment lawsuit and the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings. Therefore, we may require additional funding within this time frame, which may include financing arrangements related to our land and buildings. For example, we recently entered into a conditional agreement to sell our land and buildings for $42.0 million and to lease back such property for an initial term of ten years. The sale is subject to certain closing conditions, including the closing of the initial public offering of the buyer. There can be no assurances that these conditions will be satisfied in a timely manner or at all. If the sale is successfully consummated, it would provide us approximately $16.0 million of additional cash after repayment of the existing mortgage. In addition, we may choose to raise additional capital due to market conditions or strategic considerations, such as an acquisition, even if we believe we have sufficient funds for our current or future operating plans. Further, any additional equity financing may be dilutive to our then existing stockholders and may adversely affect their rights.

     On December 23, 2003, we filed a shelf registration statement that would allow us to raise up to $65 million of funding through the sale of common stock in one or more transactions. On May 14, 2004, we raised approximately $28.7 million, net of offering expenses, through the sale of our common stock under this shelf registration statement. We currently do not have plans to raise additional funds under this registration statement.

Critical Accounting Policies

Revenue Recognition

Table of Contents

ILLUMINA, INC.
Management’s Discussion and Analysis of Financial
Condition and Results of Operations (continued)

     We recognize revenue in accordance with the guidelines established by SEC Staff Accounting Bulletin (SAB) No. 101. Under SAB 101, revenue cannot be recorded until all of the following criteria have been met: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the seller’s price to the buyer is fixed or determinable; and collectibility is reasonably assured. Product revenue consists of sales of oligonucleotides, arrays, assay reagents, genotyping systems and gene expression systems. Services revenue consists of revenue received for performing genotyping services. Revenue for product sales is recognized generally upon shipment and transfer of title to the customer, provided no significant obligations remain and collection of the receivables is reasonably assured. BeadLab genotyping system revenue is recognized when earned, which is generally upon shipment, installation, training and fulfillment of contractually defined acceptance criteria. Reserves are provided for anticipated product warranty expenses at the time the associated revenue is recognized. Revenue for genotyping services is recognized generally at the time the genotyping analysis data is delivered to the customer. We have been awarded $9.1 million from the National Institutes of Health to perform genotyping services in connection with the International HapMap Project. A portion of the revenue from this project is earned at the time the related costs are incurred while the remainder of the revenue is earned upon the delivery of genotyping data. Research revenue consists of amounts earned under research agreements with government grants, which is recognized in the period during which the related costs are incurred. All revenues are recorded net of any applicable allowances for returns or discounts.

     We received $10.0 million of non-refundable research funding from Applied Biosystems in connection with a licensing and development contract entered into in 1999. This amount was originally recorded as deferred revenue in accordance with the provisions of SAB 101 and would have been recognized as revenue at a contractually defined rate of 25% of the defined operating profit earned from sales of the products covered by the collaboration agreement, had such sales occurred. We do not believe a collaboration product will be commercialized under the partnership agreement, and there are legal proceedings between the parties as more fully described above. The $10.0 million of research funding was reclassified to an advance payment from former collaborator until the legal proceedings have been resolved.

Cash & Investments

     We invest our excess cash balances in marketable debt securities, primarily government securities and corporate bonds and notes, with strong credit ratings or short maturity mutual funds holding such securities. We classify our investments as “Available-for-Sale” under SFAS 115 and record such investments at the estimated fair value in the balance sheet, with gains and losses, if any, reported in stockholders’ equity. We periodically review our investments for other than temporary impairment.

Factors Affecting Our Operating Results

     Our business is subject to various risks, including those described below. In addition to the other information included in this Form 10-Q, the following issues could adversely affect our operating results or our stock price.

We have generated only a small amount of revenue from product and service offerings to date. We expect to continue to incur net losses and we may not achieve or maintain profitability.

     We have incurred net losses since our inception and expect to continue to incur net losses at least through the end of 2004. At June 27, 2004, our accumulated deficit was approximately $124.9 million, and we incurred a net loss of $7.5 million for the six months ended June 27, 2004. The magnitude of our net losses will depend, in part, on the rate of growth, if any, of our revenue and on the level of our expenses. We expect to continue incurring significant expenses for research and development, for developing our manufacturing capabilities and for sales and marketing efforts to commercialize our products. In addition, we expect that our selling and marketing expenses will increase at a higher rate in the future as a result of the launch of new products. As a result, we expect that our operating expenses will increase significantly as we grow and, consequently, we will need to generate significant

additional revenue to achieve profitability. Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis.

Our success depends upon the increasing availability of genetic information and the continued emergence and growth of markets for analysis of genetic variation and function.

     We design our products primarily for applications in the life sciences and pharmaceutical industries. The usefulness of our technology depends in part upon the availability of genetic data and its usefulness in identifying or treating disease. We are initially focusing on markets for analysis of genetic variation and function, namely SNP genotyping and gene expression profiling. Our first products are being sold into the SNP genotyping and focused-gene expression markets. Both of these markets are new and emerging, and they may not develop as quickly as we anticipate, or reach their full potential. Other methods of analysis of genetic variation and function may emerge and displace the methods we are developing. Also, researchers may not seek or be able to convert raw genetic data into medically valuable information through the analysis of genetic variation and function. If useful genetic data is not available or if our target markets do not develop in a timely manner, demand for our products may grow at a slower rate than we expect, and we may never become profitable.

We are an early stage company with a limited history of commercial sales of systems and consumable products, and our success depends on our ability to develop commercially successful products and on market acceptance of our new and relatively unproven technologies.

     We may not possess all of the resources, capability and intellectual property necessary to develop and commercialize all the products or services that may result from our technologies. Sales of our genotyping and gene expression systems only began in 2003, and some of our other technologies are in the early stages of commercialization or are still in development. You should evaluate us in light of the uncertainties and complexities affecting an early stage company developing tools for the life sciences and pharmaceutical industries. We must conduct a substantial amount of additional research and development before some of our products will be ready for sale. Problems frequently encountered in connection with the development or early commercialization of products and services using new and relatively unproven technologies might limit our ability to develop and successfully commercialize these products and services. In addition, we may need to enter into agreements to obtain intellectual property necessary to commercialize some of our products or services.

     Historically, life sciences and pharmaceutical companies have analyzed genetic variation and function using a variety of technologies. In order to be successful, our products must meet the commercial requirements of the life sciences and pharmaceutical industries as tools for the large-scale analysis of genetic variation and function.

     Market acceptance will depend on many factors, including:

  our ability to demonstrate to potential customers the benefits and cost effectiveness of our products and services relative to others available in the market;
 
  the extent and effectiveness of our efforts to market, sell and distribute our products;
 
  our ability to manufacture products in sufficient quantities with acceptable quality and reliability and at an acceptable cost; and
 
  the willingness and ability of customers to adopt new technologies requiring capital investments.

Litigation or other proceedings or third party claims of intellectual property infringement could require us to spend significant time and money and could prevent us from selling our products or services.

     Our commercial success depends in part on our non-infringement of the patents or proprietary rights of third parties and the ability to protect our own intellectual property. Applied Biosystems has served us with an amended complaint alleging patent infringement, Affymetrix has filed a complaint against us alleging infringement of six of its patents, and other third parties have or may assert that we are employing their proprietary technology without authorization. As we enter new markets, we expect that competitors will likely assert that our products infringe their intellectual property rights as part of a business strategy to impede our successful entry into those markets. In addition, third parties have or may obtain patents in the future and claim that use of our technologies infringes these patents. We could incur substantial costs and divert the attention of our management and technical personnel in defending ourselves against any of these claims. We may incur the same costs and diversions in enforcing our patents against others. Furthermore, parties making claims against us may be able to obtain injunctive or other relief, which effectively could block our ability to further develop, commercialize and sell products, and could result in the award of substantial damages against us. In the event of a successful claim of infringement against us, we may be required to pay damages and obtain one or more licenses from third parties, or be prohibited from selling certain products. We may not be able to obtain these licenses at a reasonable cost, or at all. In that event, we could encounter delays in product introductions while we attempt to develop alternative methods or products. Defense of any lawsuit or failure to obtain any of these licenses could prevent us from commercializing available products, and the prohibition of sale of any of our products could materially affect our ability to grow and to attain profitability.

Any inability to adequately protect our proprietary technologies could harm our competitive position.

     Our success will depend in part on our ability to obtain patents and maintain adequate protection of our intellectual property in the United States and other countries. If we do not protect our intellectual property adequately, competitors may be able to use our technologies and thereby erode our competitive advantage. The laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and many companies have encountered significant problems in protecting their proprietary rights abroad. These problems can be caused by the absence of rules and methods for defending intellectual property rights.

     The patent positions of companies developing tools for the life sciences and pharmaceutical industries, including our patent position, generally are uncertain and involve complex legal and factual questions. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. We will apply for patents covering our technologies and products, as we deem appropriate. However, our patent applications may be challenged and may not result in issued patents. Our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from practicing our technologies or from developing competing products. There also is risk that others may independently develop similar or alternative technologies or design around our patented technologies.

     In April 2003, Applied Biosystems served us with an amended complaint alleging patent infringement, asserting that our genotyping products infringe several patents owned by Applied Biosystems, and in July 2004, Affymetrix filed a complaint alleging that our products infringe six of its patents. Others may challenge or invalidate our patents or claim that we infringe the rights of third party patents. However, we are not aware of any other such parties that currently intend to pursue patent infringement claims against us. Also, our patents may fail to provide us with any competitive advantage. We may need to initiate additional lawsuits to protect or enforce our patents, or litigate against third party claims, which would be expensive and, if we lose, may cause us to lose some of our intellectual property rights and reduce our ability to compete in the marketplace.

     We also rely upon trade secret protection for our confidential and proprietary information. We have taken security measures to protect our proprietary information. These measures, however, may not provide adequate protection for our trade secrets or other proprietary information. We seek to protect our proprietary information by entering into confidentiality agreements with employees, collaborators and consultants. Nevertheless, employees,

24

Management’s Discussion and Analysis of Financial
Condition and Results of Operations (continued)

collaborators or consultants may still disclose our proprietary information, and we may not be able to meaningfully protect our trade secrets. In addition, others may independently develop substantially equivalent proprietary information or techniques or otherwise gain access to our trade secrets.

We have limited experience in manufacturing commercial products.

     We have limited experience manufacturing our products in the volumes that will be necessary for us to achieve significant commercial sales. We have only recently begun manufacturing products on a commercial scale and, in the past, we have experienced variations in manufacturing conditions that have temporarily reduced production yields. Due to the intricate nature of manufacturing products that contain DNA, we may encounter similar or previously unknown manufacturing difficulties in the future that could significantly reduce production yields, impact our ability to sell these products, or to produce them economically, may prevent us from achieving expected performance levels or cause us to set prices that hinder wide adoption by customers.

Our sales, marketing and technical support organization may limit our ability to sell our products.

     We currently have fewer resources available for sales and marketing and technical support services as compared to our primary competitors and have only recently established a small direct sales force and customer support team. In order to effectively commercialize our genotyping and gene expression systems and other products to follow, we will need to expand our sales, marketing and technical support staff both domestically and internationally. We may not be successful in establishing or maintaining either a direct sales force or distribution arrangements to market our products and services. In addition, we compete primarily with much larger companies, that have larger sales and distribution staffs and a significant installed base of products in place, and the efforts from a limited sales and marketing force may not be sufficient to build the market acceptance of our products required to support continued growth of our business.

We expect intense competition in our target markets, which could render our products obsolete, result in significant price reductions or substantially limit the volume of products that we sell. This would limit our ability to compete and achieve profitability. If we cannot continuously develop and commercialize new products, our revenues may not grow as intended.

     We compete with life sciences companies that design, manufacture and market instruments for analysis of genetic variation and function and other applications using technologies such as two-dimensional electrophoresis, capillary electrophoresis, mass spectrometry, flow cytometry, microfluidics, and mechanically deposited, inkjet and photolithographic arrays. We anticipate that we will face increased competition in the future as existing companies develop new or improved products and as new companies enter the market with new technologies. The markets for our products are characterized by rapidly changing technology, evolving industry standards, changes in customer needs, emerging competition, new product introductions and strong price competition. For example, Affymetrix recently released a 100k SNP genotyping chip and several competitors have begun selling a single chip for whole human genome expression which may compete with our SNP genotyping service and product offerings and our gene expression product offerings. One or more of our competitors may render our technology obsolete or uneconomical. Our competitors have greater financial and personnel resources, broader product lines, a more established customer base and more experience in research and development than we have. Furthermore, the life sciences and pharmaceutical companies, which are our potential customers and strategic partners, could develop competing products. If we are unable to develop enhancements to our technology and rapidly deploy new product offerings, our business, financial condition and results of operations will suffer.

If we are unable to develop our manufacturing capability, we may not be able to launch or support our products in a timely manner, or at all.

     We currently possess only one facility capable of manufacturing our products and services for both sale to our customers and internal use. If a natural disaster were to significantly damage our facility or if other events were to cause our operations to fail, these events could prevent us from developing and manufacturing our products and services.

If we are unable to find third-party manufacturers to manufacture components of our products, we may not be able to launch or support our products in a timely manner, or at all.

     The nature of our products requires customized components that currently are available from a limited number of sources. For example, we currently obtain the fiber optic bundles and BeadChip slides included in our products from single vendors. If we are unable to secure a sufficient supply of those or other product components, we will be unable to meet demand for our products. We may need to enter into contractual relationships with manufacturers for commercial-scale production of some of our products, or develop these capabilities internally, and we cannot assure you that we will be able to do this on a timely basis, for sufficient quantities or on commercially reasonable terms. Accordingly, we may not be able to establish or maintain reliable, high-volume manufacturing at commercially reasonable costs.

We may encounter difficulties in managing our growth. These difficulties could increase our losses.

     We expect to experience rapid and substantial growth in order to achieve our operating plans, which will place a strain on our human and capital resources. If we are unable to manage this growth effectively, our losses could increase. Our ability to manage our operations and growth effectively requires us to continue to expend funds to enhance our operational, financial and management controls, reporting systems and procedures and to attract and retain sufficient numbers of talented employees. If we are unable to scale up and implement improvements to our manufacturing process and control systems in an efficient or timely manner, or if we encounter deficiencies in existing systems and controls, then we will not be able to make available the products required to successfully commercialize our technology. Failure to attract and retain sufficient numbers of talented employees will further strain our human resources and could impede our growth.

We may need additional capital in the future. If additional capital is not available on acceptable terms, we may have to curtail or cease operations.

     Our future capital requirements will be substantial and will depend on many factors including our ability to successfully market our genetic analysis systems and services, the need for capital expenditures to support and expand our business, the progress and scope of our research and development projects, the filing, prosecution and enforcement of patent claims, the success of our legal proceedings with Applied Biosystems, the appeal of a wrongful termination lawsuit and the need to enter into collaborations with other companies or acquire other companies or technologies to enhance or complement our product and service offerings. We anticipate that our existing capital resources will enable us to maintain currently planned operations for at least 24 months. However, we premise this expectation on our current operating plan, which may change as a result of many factors. Consequently, we may need additional funding within this timeframe, which may include financing arrangements related to our land and buildings as discussed in “Liquidity and Capital Resources” above. Our inability to raise capital would seriously harm our business and product development efforts. In addition, we may choose to raise additional capital due to market conditions or strategic considerations, such as an acquisition, even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity, the issuance of these securities could result in dilution to our stockholders.

     We currently have no credit facility or committed sources of capital available as of June 27, 2004. To the extent operating and capital resources are insufficient to meet future requirements; we will have to raise additional funds to continue the development and commercialization of our technologies. These funds may not be available on favorable terms, or at all. If adequate funds are not available on attractive terms, we may be required to curtail

operations significantly or to obtain funds by entering into financing, supply or collaboration agreements on unattractive terms.

If we lose our key personnel or are unable to attract and retain additional personnel, we may be unable to achieve our goals.

     We are highly dependent on our management and scientific personnel, including Jay Flatley, our president and chief executive officer, David Barker, our vice president and chief scientific officer, and John Stuelpnagel, our senior vice president of operations. The loss of their services could adversely impact our ability to achieve our business objectives. We will need to hire additional qualified personnel with expertise in molecular biology, chemistry, biological information processing, sales, marketing and technical support. We compete for qualified management and scientific personnel with other life science companies, universities and research institutions, particularly those focusing on genomics. Competition for these individuals, particularly in the San Diego area, is intense, and the turnover rate can be high. Failure to attract and retain management and scientific personnel would prevent us from pursuing collaborations or developing our products or technologies.

     Our planned activities will require additional expertise in specific industries and areas applicable to the products developed through our technologies, including the life sciences and healthcare industries. Thus, we will need to add new personnel, including management, and develop the expertise of existing management. The failure to do so could impair the growth of our business.

     A significant portion of our sales are to international customers.

     Approximately 53% of our revenues for the six months ended June 27, 2004 were derived from customers outside the United States. We intend to continue to expand our international presence and export sales to international customers and we expect the total amount of non-U.S. sales to continue to grow. Export sales entail a variety of risks, including:

  currency exchange fluctuations;
 
  unexpected changes in legislative or regulatory requirements of foreign countries into which we import our products;
 
  difficulties in obtaining export licenses or other trade barriers and restrictions resulting in delivery delays; and
 
  significant taxes or other burdens of complying with a variety of foreign laws.

     In addition, sales to international customers typically result in longer payment cycles and greater difficulty in accounts receivable collection. We are also subject to general geopolitical risks, such as political, social and economic instability and changes in diplomatic and trade relations. One or more of these factors could have a material adverse effect on our business, financial condition and operating results.

We expect that our results of operations will fluctuate. This fluctuation could cause our stock price to decline.

     A significant portion of our revenue is derived from a few large, individual transactions such as the sale of BeadLab production genotyping systems and large genotyping services contracts, including our work on the International HapMap Project. Because these transactions may not occur regularly and there is a lengthy sales cycle for such transactions, revenue of these types may not occur on a consistent or frequent basis. In addition, our total amount of revenues is subject to fluctuations in demand from seasonality impacts, the timing and amount of government grant funding programs, the timing and size of research projects our customers perform and changes in overall spending levels in the life sciences industry. Given the difficulty in predicting the timing and magnitude of sales for our products, we may experience quarter-to-quarter fluctuations in revenue resulting in the potential for a sequential decline in quarterly revenue. A large portion of our expenses are relatively fixed, including expenses for facilities, equipment and personnel. In addition, we expect operating expenses to continue to increase significantly.

Condition and Results of Operations (continued)

Accordingly, if revenue does not grow as anticipated, we may not be able to reduce our operating losses. Due to the possibility of fluctuations in our revenue and expenses, we believe that quarterly comparisons of our operating results are not a good indication of our future performance. If our operating results fluctuate or do not meet the expectations of stock market analysts and investors, our stock price probably would decline.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

     Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio. The fair market value of fixed rate securities may be adversely impacted by fluctuations in interest rates while income earned on floating rate securities may decline as a result of decreases in interest rates. Under our current policies, we do not use interest rate derivative instruments to manage exposure to interest rate changes. We ensure the safety and preservation of our invested principal funds by limiting default risk, market risk and reinvestment risk. We mitigate default risk by investing in investment grade securities. A hypothetical 100 basis point adverse move in interest rates along the entire interest rate yield curve would not materially affect the fair value of our interest sensitive financial instruments.

     In January 2002, we assumed a $26.0 million mortgage in connection with the purchase of a new facility and related land. The interest rate on this loan is fixed for a 10-year period and consequently there is no exposure to increasing market interest rates.

     We are exposed to the risk of future currency exchange rate fluctuations, which is accounted for as an adjustment to stockholders’ equity. Exchange gains and losses arising from transactions denominated in foreign currencies are recorded in operations and have historically not been material. Nonetheless, changes from reporting period to reporting period in the exchange rates between various foreign currencies and the U.S. dollar have had and will continue to have an impact on the accumulated other comprehensive income component of stockholders’ equity reported by us, and such effect in the accounts of our foreign subsidiaries may become material in a reporting period.

Item 4. Controls and Procedures

     We have established and maintain disclosure controls and procedures to ensure that we record, process, summarize, and report information we are required to disclose in our periodic reports filed with the Securities and Exchange Commission in the manner and within the time periods specified in the SEC’s rules and forms. We also design our disclosure controls to ensure that the information is accumulated and communicated to our management, including the chief executive officer and the chief financial officer, as appropriate to allow timely decisions regarding required disclosure. We also maintain internal controls and procedures to ensure that we comply with applicable laws and our established financial policies. We design our internal controls to provide reasonable assurance that (1) our transactions are properly authorized; (2) our assets are safeguarded against unauthorized or improper use; and (3) our transactions are properly recorded and reported in conformity with accounting principles generally accepted in the United States.

     We have evaluated the design and operation of our disclosure controls and procedures to determine whether they are effective in ensuring that the disclosure of required information is timely made in accordance with the Exchange Act and the rules and regulations of the Securities and Exchange Commission. This evaluation was made under the supervision and with the participation of management, including our chief executive officer and chief financial officer as of June 27, 2004. Our management does not expect that our disclosure controls or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of 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, have been detected. These

28

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. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon 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 the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. Notwithstanding, we have designed our internal control system with a level of controls that we believe will prevent material errors in our consolidated financial statements.

     The chief executive officer and chief financial officer have concluded, based on their review, that our disclosure controls and procedures, as defined by Exchange Act Rules 13a-15(e) and 15d-15(e), are effective to ensure that information required to be disclosed by us in reports that we file under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. No significant changes were made to our internal controls or other factors that could significantly affect these controls during the second quarter of 2004.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

     In March 2001, a complaint seeking damages of an unspecified amount was filed against us by a former employee in the Superior Court of the State of California in connection with the employee’s termination of employment with Illumina. In July 2002 a California Superior Court judgment was rendered against the Company and we recorded a $7.7 million charge in our financial results for the second quarter of 2002 to cover total damages and remaining expenses. We believe that the termination was lawful in all respects and that the verdict was unsupported by evidence presented at the trial. A notice of appeal in this case was filed on October 10, 2002, and the appeal process is ongoing. The briefing for the appeal has been completed and an oral argument before the appeals court is expected to occur in the third quarter of 2004. We are also recording interest expense on the $7.7 million during the appeal based on the statutory rate.

     In December 2002, Applied Biosystems filed a complaint, and later amended and refiled a complaint in March 2003, for a patent infringement suit against us in the federal court in Northern California asserting infringement of several patents related to an Applied Biosystems’ assay intended for use in our collaboration. Applied Biosystems seeks a judgment granting it damages for infringement, treble damages alleging that such infringement is willful and a permanent injunction restraining us from the alleged infringement. We have answered the complaint, asserting various defenses, including that we do not infringe the patents or that the patents are invalid, and asserting counterclaims against Applied Biosystems seeking declaratory judgment relief related to the patents being asserted against us, and seeking damages from Applied Biosystems for its alleged unfair and unlawful conduct which constitutes attempted monopolization in violation of the antitrust laws. This action is currently stayed pending the outcome of an arbitration proceeding between the parties.

     Also in December 2002, Applied Biosystems sent a notification to us alleging that we had breached the joint development agreement between Illumina and Applied Biosystems entered into in November 1999 and seeking to compel arbitration pursuant to that agreement. This notification alleged that our production-scale genotyping products and services are collaboration products developed under the joint development agreement, and that our commercial activities with respect to our genotyping products and services are unlawful, unfair or fraudulent. Among other relief, Applied Biosystems is seeking compensatory damages of $30 million, disgorgement of all revenues received from sales of these products and services and a prohibition of future sales of these products or services.

     In December 2002, we filed a suit alleging breach of contract, breach of the implied covenant of good faith and fair dealing, unfair competition and other allegations against Applied Biosystems in San Diego Superior Court, and a motion for a temporary restraining order to prevent the arbitration of our joint development agreement sought by Applied Biosystems. In January 2004, we notified Applied Biosystems that we were terminating the joint development agreement.

     In December 2003, after having granted temporary and preliminary injunctions staying the arbitration, the San Diego Superior Court directed Applied Biosystems and us to resolve the contract dispute in a binding arbitration procedure. After the Superior Court ordered the parties to the arbitration process, Applied Biosystems purported to amend its demands for arbitration to add new allegations against us (including claims of malicious prosecution, abuse of process, fraud in the inducement, interference with a prospective economic advantage, declaratory judgment that the joint development agreement had not been terminated and a new claim of breach of contract based on alleged poor quality of our arrays) and to increase its demand for cash damages to an unspecified amount in excess of $60 million. An arbitrator has been selected, and the arbitration hearing is currently scheduled to be completed in December 2004, with a written decision from the arbitrator expected in early 2005.

     We will vigorously defend against the claims alleged by Applied Biosystems but the outcome of an arbitration proceeding is inherently uncertain and we cannot be sure that we will prevail. This arbitration could result in a range of potential outcomes, based solely on the judgment and discretion of the arbitrator, including (1) the award of all damages and injunctive relief sought by Applied Biosystems; (2) the award of all damages and relief sought by us; or (3) a partial award of damages and/or injunctive relief to either party. We have not accrued for any

potential losses in this case because we believe that an adverse determination is not probable, and potential losses cannot be reasonably estimated. However, our financial statements include a $10.0 million advance payment from Applied Biosystems that would have been deducted from the profits otherwise payable to us from Applied Biosystems had the collaboration been successful and which could offset the impact on our consolidated results of operations of an adverse arbitration determination up to that amount. Any unfavorable arbitration determination, and in particular any significant cash amounts required to be paid by the Company or prohibition of the sale of our products or services, could result in a material adverse effect on our business, financial condition and results of operations.

     We are in the early stages of proceedings in the patent case brought by Applied Biosystems. In February 2004, the federal district court in Northern California ordered that the patent case be stayed pending completion of the arbitration process. We intend to vigorously defend against the claims alleged by Applied Biosystems and continue to pursue our counterclaims against Applied Biosystems. However, we cannot be sure that we will prevail in these matters. Any unfavorable determination, and in particular any significant cash amounts required to be paid by us or prohibition of the sale of our products or services, could result in a material adverse effect on our business, financial condition and results of operations.

     In July 2004, Affymetrix filed a complaint in the U.S. District Court for the District of Delaware alleging that certain of our products infringe six Affymetrix patents. The suit seeks an unspecified amount of monetary damages and a judgment enjoining the sale of products, if any, that are determined to be infringing these patents. We have not yet responded to this complaint but believe we have meritorious defenses against each of the patents alleged by Affymetrix and intend to vigorously defend ourselves against this suit. However, we cannot be sure we will prevail in this matter. Any unfavorable determination, and in particular, any significant cash amounts required to be paid by us or prohibition of the sale of our products and services, could result in a material adverse effect on our business, financial condition and results of operations.

Item 2. Changes in Securities and Use of Proceeds

     On July 27, 2000, we commenced our initial public offering pursuant to a Registration Statement on Form S-1 (File No. 333-33922) resulting in net offering proceeds of $101.3 million. We will continue to use proceeds from our initial public offering to fund operations. Through June 27, 2004, we have used approximately $19.4 million to purchase property, plant and equipment and approximately $44.4 million to fund general operating expenses. The remaining balance is invested in a variety of interest-bearing instruments including U.S. Treasury securities, corporate debt securities and money market accounts.
