Illumina, Inc.

Notes to Condensed Consolidated Financial Statements

(Unaudited)

Unless the context requires otherwise, references in this report to “Illumina,” “we,” “us,” the “Company,” and “our” refer to Illumina, Inc. and its consolidated subsidiaries.

1. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) 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 GAAP for complete financial statements. Interim financial results are not necessarily indicative of results anticipated for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the fiscal year ended January ~~3, 2016,~~1, 2017, from which the balance sheet information herein was derived. The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expense, and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

The unaudited condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, majority-owned or controlled companies, and variable interest entities (VIEs) for which the Company is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation. Effective February 28, 2017, Illumina deconsolidated GRAIL, Inc.’s financial statements. In management’s opinion, the accompanying financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the results for the interim periods presented.

The Company evaluates its ownership, contractual and other interests in entities that are not wholly-owned by the Company to determine if these entities are VIEs, and, if so, whether the Company is the primary beneficiary of the VIE. In determining whether the Company is the primary beneficiary of a VIE and is therefore required to consolidate the VIE, the Company applies a qualitative approach that determines whether it has both (1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses of, or the rights to receive benefits from, the VIE that could potentially be significant to that VIE. The Company continuously assesses whether it is the primary beneficiary of a VIE as changes to existing relationships or future transactions may result in the consolidation or deconsolidation, as the case may be. The Company has not provided financial or other support during the periods presented to its VIEs that it was not previously contractually required to provide.

The equity method is used to account for investments in which the Company has the ability to exercise significant influence, but not control, over the investee. Such investments are recorded within other assets, and the share of net income or losses of equity investments is recognized on a one quarter lag in other ~~(expense)~~ income, net.

Redeemable Noncontrolling Interests

Noncontrolling interests represent the portion of equity (net assets) in a consolidated entity that is not wholly-owned by the Company that is not attributable, directly or indirectly, to the Company. Noncontrolling interests with embedded contingent redemption features, such as put rights, that are not solely within the Company’s control are considered redeemable noncontrolling interests. Redeemable noncontrolling interests are presented outside of stockholders’ equity on the condensed consolidated balance sheets.

Segment Information

The Company is organized into three operating segments for purposes of evaluating its business operations and ~~reporting~~reviewing its financial results. One ~~operating~~ segment consists of Illumina’s core operations ~~and the~~(Core Illumina). The other two segments relate to the ~~Company’s consolidated VIEs. The combined results of operations~~activities of the Company’s consolidated variable interest entities (Consolidated VIEs), GRAIL and Helix, and are reported on an aggregate basis. Following the GRAIL deconsolidation on February 28, 2017, the Consolidated VIEs became material for the three and nine months ended October 2, 2016. As such, the Company commenced reporting two segments in the third quarter of 2016. Financial information for all periods presented has been classified to reflect these changes to our reportable segments.no longer include GRAIL. For further information on the Company’s segments, refer to note “9. Segment Information”.

Fiscal Year

The Company’s fiscal year consists of 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, September 30, and December 31. The three ~~and nine~~ months ended ~~October~~April 2, ~~2016~~2017 and ~~September 27, 2015~~April 3, 2016 were both 13 ~~and 39 weeks, respectively.~~weeks.

During the three ~~and nine~~ months ended ~~October~~April 2, ~~2016,~~2017, there have been no changes to the Company’s significant accounting policies as described in the Annual Report on Form 10-K for the fiscal year ended January ~~3, 2016.~~1, 2017.

~~Recent~~Recently Adopted Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board issued Accounting Standard Update (ASU) 2016-09, Compensation - Stock Compensation (Topic 718), which aims to simplify the accounting for share-based payment transactions, including accounting for income taxes, classification on the statement of cash flows, accounting for forfeitures, and classification of awards as either liabilities or equity. This ASU is effective for the Company beginning in the first quarter of 2017.

Under the ASU, excess tax benefits from share-based payment arrangements are classified as discrete items within the provision for income taxes, rather than recognizing excess tax benefits in additional paid-in capital. As of April 2, 2017, the Company recorded $45 million, net, to retained earnings primarily related to unrealized tax benefits associated with share-based compensation. During the three months ended April 2, 2017, excess tax benefits of $8 million were reflected as a component of the provision for income taxes.

In addition, under the ASU, excess income tax benefits from share-based compensation arrangements are classified as cash flow from operations, rather than cash flow from financing activities. The Company has elected to apply the cash flow classification guidance retrospectively and reclassified $59 million from financing activity to operating activity for the three months ended April 3, 2016.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). The new standard ~~requires income tax effects~~is based on the principle that revenue should be recognized to depict the transfer of ~~stock compensation awards~~promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be ~~recognized~~entitled in exchange for those goods or services. Since its initial release, the ~~income statement when~~FASB has issued several amendments to the ~~awards vest or are settled. The new~~ standard, ~~also allows~~which include clarification of accounting guidance related to identification of performance obligations, intellectual property licenses, and principal vs. agent considerations.

ASU 2014-09 and all subsequent amendments (collectively, the Company to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. ASU 2016-09“new standards”) will be effective for the Company beginning in the first quarter of ~~2017.~~ 2018 and may be applied using either the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application.

The Company ~~is currently~~formed an implementation team in 2016 to oversee adoption of the new standards. The implementation team has completed its initial assessment of the new standards, including a detailed review of the Company’s contract portfolio and revenue streams, particularly around product revenues, to identify potential differences in accounting as a result of the new standards. It performed an analysis of those differences and formed preliminary conclusions on the expected changes. While the team’s analysis to date suggests the impact of adoption will not have a material impact on the Company’s existing revenue accounting policies or financial statements, there are a number of steps in the team’s project plan that remain to be completed including: finalizing contract reviews, evaluating the impact on the Company’s services and other revenue streams, and working through anticipated changes to systems, business processes and controls to support the adoption of the new standards. Assuming the impact is not material, the Company expects to adopt the new standards using the modified retrospective method with an adjustment to beginning retained earnings for the cumulative effect of the change.

In January 2016, the Financial Accounting Standards Board issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10), which requires equity investments (other than those accounted for under the equity method or those that result in consolidation) to be measured at fair value, with changes in fair value recognized in net income. ASU 2016-01 will be effective for the Company beginning in the first quarter of 2018. The Company anticipates that the adoption of ASU ~~2016-09 on its consolidated financial statements.~~2016-01 may increase the volatility of other income and expense, net, as a result of the remeasurement of the Company’s cost-method investments.

In February 2016, the Financial Accounting Standards Board issued ASU 2016-02, Leases (Topic 842). The new standard requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets and eliminates certain real estate-specific provisions. ASU 2016-02 will be effective for the Company beginning in the first quarter of 2019. ASU 2016-02 will be adopted on a modified retrospective transition basis for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating the impact of ASU 2016-02 on its consolidated financial statements.

In ~~May 2014,~~June 2016, the ~~Financial Accounting Standards Board~~FASB issued ASU ~~2014-09,~~2016-13, ~~Revenue from Contracts with Customers (Topic 606)~~Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments~~.

Earnings per Share

Basic earnings per share attributable to Illumina stockholders is computed based on the weighted average number of common shares outstanding during the period. Diluted earnings per share attributable to Illumina stockholders is computed based on the sum of the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Per-share earnings of our VIEs are included in the Company’s consolidated basic and diluted earnings per share computations based on the Company’s share of the ~~VIE’s~~VIEs’ securities.

Potentially dilutive common shares consist of shares issuable under convertible senior notes, equity awards, and warrants. Convertible senior notes have a dilutive impact when the average market price of the Company’s common stock exceeds the applicable conversion price of the respective notes. Potentially dilutive common shares from equity awards and warrants are determined using the average share price for each period under the treasury stock method. In addition, ~~the following amounts are assumed to be used to repurchase shares:~~ proceeds from exercise of equity awards and ~~warrants;~~warrants, and the average amount of unrecognized compensation expense for equity ~~awards; and estimated tax benefits that will~~awards are assumed to be ~~recorded in additional paid-in capital when expenses related~~used to ~~equity awards become deductible.~~repurchase shares. In loss periods, basic net loss per share and diluted net loss per share are identical because the otherwise dilutive potential common shares become anti-dilutive and are therefore excluded.

The following table presents the calculation of weighted average shares used to calculate basic and diluted earnings per share (in ~~thousands)~~millions):

~~On April 5, 2016,~~February 22, 2017, the Company entered into a lease agreement for ~~certain office buildings being constructed~~a building under construction in ~~San Diego, California.~~Madison, Wisconsin. Minimum lease payments during the initial 15-year term ~~of ten years~~ are estimated to be ~~$127.4~~$46 million.

The Company evaluates whether it is the accounting owner of leased assets during the construction period when the Company is involved in the construction of leased assets.

Investments in Consolidated Variable Interest Entities

GRAIL, Inc.

In January 2016, the Company obtained a majority equity ownership interest in GRAIL, ~~Inc. (GRAIL),~~ a company formed with unrelated third party investors to ~~pursue the development and commercialization of~~develop a blood test for ~~asymptomatic~~early-stage cancer ~~screening.~~detection. The Company determined that GRAIL iswas a variable interest entity as the entity ~~lacks~~lacked sufficient equity to finance its activities without additional support. Additionally, the Company determined that it ~~has~~had (a) control of ~~the entity’s Board~~GRAIL’s board of ~~Directors,~~directors, which ~~has~~had unilateral power over the activities that most significantly ~~impact~~impacted the economic performance of GRAIL and (b) the obligation to absorb losses of and the right to receive benefits from GRAIL that ~~are~~were potentially significant to GRAIL. As a result, the Company iswas deemed to be the primary beneficiary of GRAIL and iswas required to consolidate GRAIL. ~~On a fully diluted basis, the Company holds a 52% equity ownership interest in GRAIL as of October 2, 2016.~~

~~During the three months ended April 3,~~In January 2016, GRAIL completed its Series A convertible preferred stock financing, raising ~~$120.0~~$120 million, of which the Company invested ~~$40.0~~$40 million. Additionally, the Company and GRAIL executed a long-term supply agreement in which the Company contributed certain perpetual licenses, employees, and discounted supply terms in exchange for ~~112.5~~113 million shares of GRAIL’s Class B ~~Common Stock.~~common stock. Such contributions ~~are~~were recorded at their historical basis as they ~~remain~~remained within the control of the Company. The ~~$80.0~~$80 million received by GRAIL from unrelated third party investors upon issuance of its Series A convertible preferred stock iswas classified as noncontrolling interests in stockholders’ equity on the Company’s condensed consolidated balance sheet.

~~During the three months ended July 3,~~In June 2016, GRAIL authorized for issuance ~~97.5~~98 million shares of Series A-1 convertible preferred stock, all of which were issued to Illumina in exchange for ~~97.5~~98 million shares of Illumina’s Class B ~~Common Stock on June 23, 2016.~~common stock. As a result of the exchange, Illumina recorded a ~~$9.5~~$10 million deemed dividend net of tax of ~~$9.6~~$10 million through equity, which was eliminated in consolidation.

Deconsolidation of GRAIL, Inc.

~~For~~On February 28, 2017, GRAIL completed the initial close of its Series B preferred stock financing, raising over $900 million, in which the Company did not participate. Concurrent with the financing, GRAIL repurchased 35 million shares of its Series A preferred stock and approximately 34 million shares of its Series A-1 preferred stock held by the Company for an aggregate purchase price of $278 million. At this time, the Company ceased to have a controlling financial interest in GRAIL and the Company’s equity ownership was reduced from 52% to 19%. Additionally, the Company’s voting interest was reduced to 13%, and the Company no longer has representation on GRAIL’s board of directors. As a result, the Company deconsolidated GRAIL’s financial statements effective February 28, 2017. In connection with the financing, the Company entered into an agreement with GRAIL that (i) requires the Company to purchase Series B preferred shares sufficient to retain a 19% ownership interest as of April 30, 2017, and (ii) provides the Company the right to purchase additional GRAIL Series B preferred shares, should the Company’s ownership interest in GRAIL fall below 19% after April 30, 2017. As of April 30, 2017, the Company’s purchase obligation is $14 million.

The operations of GRAIL from January 2, 2017 up to the date of deconsolidation are included in the accompanying condensed consolidated statements of income for the three months ended ~~October~~April 2, ~~2016,~~2017. During this period, the Company absorbed approximately 50% of GRAIL’s losses based upon its proportional ownership of GRAIL’s common stock. ~~Prior~~

For the three months ended April 2, 2017, the Company recorded a pretax gain of $453 million included in other income and expense, net, of which $159 million relates to the ~~exchange,~~remeasurement of the Company’s retained equity interest to its fair value. The pretax gain on deconsolidation includes (i) the consideration received from GRAIL for its repurchase of a portion of the ~~six months ended July~~Company’s ownership interest, (ii) the derecognition of the carrying amounts of GRAIL’s assets and liabilities, (iii) the derecognition of the noncontrolling interest related to GRAIL and (iv) the recording of the Company’s remaining interest in GRAIL at fair value. This fair value measurement of the Company’s remaining interest was derived using the market approach. Significant estimates and assumptions required for this valuation included, but were not limited to, various Black-Scholes option-pricing model assumptions as of the date of deconsolidation and estimated discounts for lack of marketability related to the equity securities. These unobservable inputs, which represent a Level 3 ~~2016,~~measurement, are supported by little or no market activity and reflect the Company’s own assumptions in measuring fair value.

The Company’s retained investment in GRAIL is accounted for under the cost method. As of April 2, 2017, the Company ~~absorbed 90%~~has recorded $171 million in other assets related to this investment. As of April 2, 2017, the Company holds 5 million Series A preferred shares and approximately 78 million Class A common shares of GRAIL, or approximately 19% of GRAIL’s ~~losses based upon its proportional ownership of GRAIL’s common~~outstanding stock.

In connection with the deconsolidation of GRAIL, the parties amended their long-term supply agreement (the Supply Agreement), including the discounted supply terms. The repurchase and supply arrangements, which were entered into concurrently, contain various elements and, as such, are deemed to be an arrangement with multiple deliverables as defined under the respective authoritative accounting guidance. The Company determined that each of the elements, which include the purchase obligation, the purchase right and services to be provided in accordance with ~~GRAIL’s Equity Incentive Plan,~~ the ~~Company may be required to redeem certain vested stock awards in cash~~long-term supply agreement, were at, ~~the then approximate fair market value. The~~or approximated, fair value on a standalone basis, and therefore, there was no discount to allocate among the deliverables. As such, none of the redeemable noncontrolling interests is considered a Level 3 instrument. Such redemption right is exercisable at the option of the holder of the awards after February 28, 2021, provided that an initial public offering of GRAIL has not been completed. As the redemption provision is outside of the control of the Company, the redeemable noncontrolling interests in GRAIL are classified outside of stockholders’ equity on the accompanying condensed consolidated balance sheets. The balance of the redeemable noncontrolling interests is reported at the greater of its carrying value after receiving its allocation of GRAIL’s profits and losses or its estimated redemption value at each reporting date.

~~The assets and liabilities of GRAIL, other than cash and cash equivalents, are not significant~~deconsolidation gain was allocated to the Company’s financial position as of October 2, 2016. Additionally, GRAIL has an immaterial impact on the Company’s condensed consolidated statements of income and cash flows for the three and nine months ended October 2, 2016.these elements.

Helix Holdings I, LLC

In July 2015, the Company obtained a 50% voting equity ownership interest in Helix Holdings I, LLC (Helix), a limited liability company formed with unrelated third party investors to pursue the development and commercialization of a marketplace for consumer genomics. The Company determined that Helix is a variable interest entity as the ~~holder~~holders of the at-risk equity investments as a group lack the power to direct the activities of Helix that most significantly impact Helix’s economic performance. Additionally, the Company determined that it has (a) unilateral power over one of the activities that most significantly impacts the economic performance of Helix through its contractual arrangements and no one individual party has unilateral power over the remaining significant activities of Helix and (b) the obligation to absorb losses of and the right to receive benefits from Helix that are potentially significant to Helix. As a result, the Company is deemed to be the primary beneficiary of Helix and is required to consolidate Helix.

As contractually committed, the Company contributed certain perpetual licenses, instruments, intangibles, initial laboratory setup, and discounted supply terms in exchange for voting equity interests in Helix. Such contributions are recorded at their historical basis as they remain within the control of the Company. Helix is financed through cash contributions made by the third party investors in exchange for voting equity interests in Helix.

Certain noncontrolling Helix investors may require the Company to redeem all noncontrolling interests in cash at the then approximate fair market value. The fair value of the redeemable noncontrolling interests is considered a Level 3 instrument. Such redemption right is exercisable at the option of certain noncontrolling interest holders after January 1, 2021, provided that a bona fide pursuit of the sale of Helix has occurred and an initial public offering of Helix has not been completed.

As the contingent redemption is outside of the control of Illumina, the redeemable noncontrolling interests in Helix are classified outside of stockholders’ equity on the accompanying condensed consolidated balance sheets. The balance of the redeemable noncontrolling interests is reported at the greater of its carrying value after receiving its allocation of Helix’s profits and losses or its estimated redemption value at each reporting date. As of ~~October~~April 2, ~~2016,~~2017, the noncontrolling shareholders and Illumina each held 50% of Helix’s outstanding voting equity interests.

The assets and liabilities of Helix are not significant to the Company’s financial position as of ~~October~~April 2, ~~2016.~~2017. Helix has an immaterial impact on the Company’s condensed consolidated statements of income and cash flows for the three ~~and nine~~ months ended ~~October~~April 2, ~~2016.~~2017.

As of ~~October~~April 2, ~~2016,~~2017, the accompanying condensed consolidated balance sheet includes ~~$103.6~~$5 million of cash and cash equivalents attributable to ~~GRAIL and~~ Helix that will be used to settle their respective obligations and will not be available to settle obligations of the Company.

The Company holds available-for-sale securities that consist of highly liquid, investment grade debt securities. The Company considers information provided by the Company’s investment accounting and reporting service provider in the measurement of fair value of its debt securities. The investment service provider provides valuation information from an industry-recognized valuation service. Such valuations may be based on trade prices in active markets for identical assets or liabilities (Level 1 inputs) or valuation models using inputs that are observable either directly or indirectly (Level 2 inputs), such as quoted prices for similar assets or liabilities, yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures. The Company’s deferred compensation plan assets consist primarily of investments in life insurance contracts carried at cash surrender value, which reflects the net asset value of the underlying publicly traded mutual funds. The Company performs control procedures to corroborate the fair value of its holdings, including comparing valuations obtained from its investment service provider to valuations reported by the Company’s asset custodians, validation of pricing sources and models, and review of key model inputs if necessary.

As a result of an acquisition completed in January 2016, the Company recorded $5.3 million in contingent consideration liabilities, the majority of which are payable within 12 months after the acquisition date. The Company reassesses the fair value of any contingent consideration liabilities on a quarterly basis using the income approach. Assumptions used to estimate the acquisition date fair value of the contingent consideration include discount rates ranging from 4% to 6% and the probability of achieving certain milestones. This fair value measurement of the contingent consideration is based on significant inputs not

observed in the market and thus represents a Level 3 measurement. Level 3 instruments are valued based on unobservable inputs that are supported by little or no market activity and reflect the Company’s own assumptions in measuring fair value.

~~Changes in estimated fair value of contingent consideration liabilities during the~~ ~~nine~~ ~~months ended~~ ~~October 2, 2016~~ ~~are as follows (in thousands):~~

4. Debt

Convertible Senior Notes

As of ~~October~~April 2, ~~2016,~~2017, the Company had outstanding ~~$632.5~~$633 million in principal amount of 0% convertible senior notes due June 15, 2019 (2019 Notes) and ~~$517.5~~$517 million in principal amount of 0.5% convertible senior notes due June 15, 2021 (2021 Notes).

0% Convertible Senior Notes due 2019 and 0.5% Convertible Senior Notes due 2021

In June 2014, the Company issued ~~$632.5~~$633 million aggregate principal amount of 2019 Notes and ~~$517.5~~$517 million aggregate principal amount of 2021 Notes. The Company used the net proceeds plus cash on hand to repurchase a portion of the outstanding 2016 Notes in privately negotiated transactions concurrently with the issuance of the 2019 and 2021 Notes. The 2019 and 2021 Notes’ mature on June 15, 2019 and June 15, 2021, respectively, and the implied estimated effective rates of the liability components of the Notes were 2.9% and 3.5%, respectively, assuming no conversion.

Both the 2019 and 2021 Notes will be convertible into cash, shares of common stock, or a combination of cash and shares of common stock, at the Company's election, based on an initial conversion rate, subject to adjustment, of 3.9318 shares per $1,000 principal amount of the notes (which represents an initial conversion price of approximately $254.34 per share), only in the following circumstances and to the following extent: (1) during the five business-day period after any 10 consecutive trading day period (the measurement period) in which the trading price per 2019 and 2021 Note for each day of such measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such day; (2) during any calendar quarter (and only during that quarter) after the calendar quarter ending September 30, 2014, if the last reported sale price of the Company’s common stock for 20 or more trading days in the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the applicable conversion price in effect on the last trading day of the immediately preceding calendar quarter; (3) upon the occurrence of specified events described in the indenture for the 2019 and 2021 Notes; and (4) at any time on or after March 15, 2019 for the 2019 Notes, or March 15, 2021 for the 2021 Notes, through the second scheduled trading day immediately preceding the maturity date.

Neither the 2019 nor the 2021 Notes were convertible as of ~~October~~April 2, ~~2016~~2017, and had no dilutive impact during the three ~~and nine~~ months ended ~~October~~April 2, ~~2016.~~2017. If the 2019 and 2021 Notes were converted as of ~~October~~April 2, ~~2016,~~2017, the if-converted value would not exceed the principal amount.

0.25% Convertible Senior Notes due 2016

In 2011, the Company issued ~~$920.0~~$920 million aggregate principal amount of 0.25% convertible senior notes due 2016 (2016 Notes) with a maturity date of March 15, 2016. The effective rate of the liability component was estimated to be 4.5%. Based upon meeting the stock trading price conversion requirement during the three months ended March 30, 2014, the 2016 Notes became convertible on April 1, 2014 through, and including, March 11, 2016. All notes were converted by March 11, 2016.

During the nine months ended October 2, 2016, the Company recorded a loss on extinguishment of debt calculated as the difference between the estimated fair value of the debt and the carrying value of the notes as of the settlement date. To measure the fair value of the converted notes as of the settlement date, the applicable interest rate was estimated using Level 2 observable inputs and applied to the converted notes using the same methodology as in the issuance date valuation. The loss recorded on extinguishment of debt for the nine months ended October 2, 2016 was immaterial.

~~The following table summarizes information about the conversion of the 2016 Notes during the nine months ended October 2, 2016 (in thousands):~~

2016 Notes
Cash paid for principal of notes converted $ 75,543
Conversion value over principal amount paid in shares of common stock $ 63,753

The repurchases may be completed under a 10b5-1 plan or at management’s discretion.

7. Income Taxes

The Company’s effective tax rate may vary from the U.S. federal statutory tax rate due to the change in the mix of earnings in tax jurisdictions with different statutory rates, benefits related to tax credits, and the tax impact of non-deductible expenses and other permanent differences between income before income taxes and taxable income. The effective tax ~~rates~~rate for the three ~~and nine~~ months ended ~~October~~April 2, ~~2016 were 24.2% and 24.9%, respectively. For the three and nine months ended October 2, 2016, the~~2017 was 30.8%. The variance from the U.S. federal statutory tax rate of 35% was primarily attributable to the offset by the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax

rate, such as in Singapore and the United ~~Kingdom;~~Kingdom, partially offset ~~slightly~~ by the discrete tax impact ~~associated with~~of $150 million from the ~~investments in our consolidated variable interest entities.~~gain on the deconsolidation of GRAIL.

8. Legal Proceedings

The Company is involved in various lawsuits and claims arising in the ordinary course of business, including actions with respect to intellectual property, employment, and contractual matters. In connection with these matters, the Company assesses, on a regular basis, the probability and range of possible loss based on the developments in these matters. A liability is recorded in the financial statements if it is believed to be probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable results could occur, assessing contingencies is highly subjective and requires judgments about future events. The Company regularly reviews outstanding legal matters to determine the adequacy of the liabilities accrued and related disclosures. The amount of ultimate loss may differ from these estimates. Each matter presents its own unique circumstances, and prior litigation does not necessarily provide a reliable basis on which to predict the outcome, or range of outcomes, in any individual proceeding. Because of the uncertainties related to the occurrence, amount, and range of loss on any pending litigation or claim, the Company is currently unable to predict their ultimate outcome, and, with respect to any pending litigation or claim where no liability has been accrued, to make a meaningful estimate of the reasonably possible loss or range of loss that could result from an unfavorable outcome. In the event that opposing litigants in outstanding litigations or claims ultimately succeed at trial and any subsequent appeals on their claims, any potential loss or charges in excess of any established accruals, individually or in the aggregate, could have a material adverse effect on the Company’s business, financial condition, results of operations, and/or cash flows in the period in which the unfavorable outcome occurs or becomes probable, and potentially in future periods.

On July 1, 2016, the Company entered into a Settlement and License Agreement with Enzo Life Sciences, Inc. (Enzo) that settled all claims in the litigation. Pursuant to the terms of the Settlement and License Agreement, the Company paid Enzo a one-time payment of $21.0 million for release of past damages claimed and a fully paid-up non-exclusive license to U.S. Patent No. 7,064,197. None of the parties made any admission of liability in entering into the Settlement and License Agreement. The Company allocated the $21.0 million settlement on a relative fair value basis, resulting in $11.5 million capitalized as an intangible asset and a corresponding gain recorded in legal contingencies for the value of the license, which will be amortized over a period of 7 years on a straight-line basis, and the remaining $9.5 million related to past damages claimed. The fair value of the license and past damages was estimated using a discounted cash flow model, and is considered to be a Level 3 measurement.

9. Segment Information

The Company has two reportable segments: Core Illumina and one segment related to the combined activities of the Company’s consolidated VIEs, GRAIL and ~~Helix.~~Helix (Consolidated VIEs). Following the GRAIL deconsolidation on February 28, 2017, the Company’s Consolidated VIEs no longer include GRAIL. The Company reports segment information based on the management approach. This approach designates the internal reporting used by the Chief Operating Decision Maker (“CODM”) for making decisions and assessing performance as the source of the Company’s reportable segments. The CODM allocates resources and assesses the performance of each operating segment using information about its revenues and income (losses) from operations. Based on the information used by the CODM, the Company has determined its reportable segments as follows:

Core Illumina:

Core Illumina’s products and services serve customers in the research, clinical and applied markets, and enable the adoption of a variety of genomic solutions. Core Illumina includes all operations of the Company, excluding the results of its ~~two~~ consolidated VIEs.

Consolidated VIEs:

GRAIL: GRAIL was created to ~~enable the early detection of~~develop a blood test for early-stage cancer ~~in asymptomatic individuals through a simple blood screen based on the concentration of circulating tumor nucleic acids.~~detection. GRAIL is currently in the early stages of developing this test and as such, has no revenues to date.

Helix: Helix was established to enable individuals to explore their genetic information by providing affordable sequencing and database services for consumers through third party partners, driving the creation of an ecosystem of consumer applications.

Management evaluates the performance of the Company’s operating segments based upon income (loss) from operations. The Company does not allocate expenses between segments. Core Illumina sells products and provides services to GRAIL and Helix in accordance with contractual agreements between the entities.

The following table presents the operating performance of each reportable segment (in ~~thousands)~~millions):

About Illumina

Our Company is organized into three operating segments for purposes of evaluating ~~its~~our business operations and ~~reporting its~~reviewing our financial results. One segment consists of Illumina’s core ~~operations.~~operations (Core Illumina). The other two segments relate to the activities of our consolidated ~~VIEs,~~variable interest entities (Consolidated VIEs), GRAIL and Helix, ~~which~~and are ~~combined into one reportable segment.~~reported on an aggregate basis. Following the GRAIL deconsolidation on February 28, 2017, our Consolidated VIEs no longer include GRAIL. For information on GRAIL and Helix, refer to ~~Note~~notes 2 and 9 of the Notes to the Condensed Consolidated Financial Statements provided in this Quarterly Report on Form 10-Q.

Our focus on innovation has established us as the global leader in ~~DNA sequencing~~sequencing- and array-based technologies, serving customers in a wide range of markets, enabling the adoption of genomic solutions in research and clinical settings.

Our customers include leading genomic research centers, academic institutions, government laboratories, and ~~applied markets. Our products are used for applications in the life sciences, oncology, reproductive health, agriculture,~~hospitals, as well as pharmaceutical, biotechnology, agrigenomics, commercial molecular diagnostic laboratories, and ~~other emerging market segments.~~consumer genomics companies.

Our portfolio of integrated systems, consumables, and analysis tools is designed to accelerate and simplify genetic analysis. This portfolio addresses athe range of genomic complexity, price points, and throughput, enabling customers to select the best solution for their research or clinical challenge.

Our financial results have been, and will continue to be, impacted by several significant trends, which are described below. While these trends are important to understanding and evaluating our financial results, this discussion should be read in conjunction with our condensed consolidated financial statements and the notes thereto in Item 1, Part I of this report, and the other transactions, events, and trends discussed in “Risk Factors” in Item 1A, Part II of this report and Item 1A of our Annual Report on Form 10-K for the fiscal year ended January ~~3, 2016~~1, 2017.

Next-Generation Sequencing

Next-generation sequencing has become an essential technology in our markets, and our portfolio of sequencing platforms represents a family of systems that are designed to meet the workflow, output, and accuracy demands of a full range of sequencing applications. We believe that the expanding sequencing market, along with an increase in the number of samples available and enhancements in our sequencing portfolio, will continue to drive demand for our next-generation sequencing technologies. As a result, we believe that our sequencing consumables revenue will continue to grow in future periods.

Arrays

As a complement to next-generation sequencing, we believe arrays offer a less expensive, faster, and highly accurate technology for use when genetic content is already known. The information content of arrays is fixed and reproducible, providing a repeatable, standardized technology to read out subsets of nucleotide bases within the overall genome. We believe that our customers, particularly in research, will migrate certain array studies to sequencing. However, we expect that demand from customers in ~~reproductive health, agriculture, and~~ applied markets who require high-throughput, cost-effective screening solutions will ~~partially mitigate this decline.~~provide growth. Demand in the array market has trended toward ~~lower complexity~~more focused arrays that can be used on larger numbers of samples, resulting in a lower selling price per sample. ~~We believe that our innovation in array products supports the lower selling price.~~

Financial Overview

Consolidated financial ~~results~~highlights for the first ~~three quarters~~quarter of ~~2016~~2017 include the following:

Net revenue increased ~~9.3%~~5% during ~~the first three quarters of 2016~~Q1 2017 to ~~$1,779.0~~$598 million compared to ~~the first three quarters of 2015~~$572 million in Q1 2016 due to the growth in sales of our sequencing consumables and genotyping services, partially offset by lower shipments of our ~~high-throughput~~HiSeq platforms. We expect our revenue to continue to increase in 2017.

Gross profit as a percentage of revenue (gross margin) was ~~70.1%~~61.5% in ~~the first three quarters of 2016~~Q1 2017 compared to ~~69.9%~~69.4% in ~~the first three quarters of 2015. Gross margins increased primarily due to a greater mix of sequencing consumables, partially offset~~Q1 2016. The gross margin decrease was driven by a ~~decline in service margin.~~variety of factors, including impairment of an acquired intangible asset, the effect of the product transition given the NovaSeq introduction, higher array services revenue, and product mix within sequencing consumables. Our gross margin in future periods will depend on several factors, including: market conditions that may impact our pricing power; sales mix changes among consumables, instruments, and services; product mix changes between established products and new products in new markets; excess and obsolete inventories; royalties; our cost structure for manufacturing operations; and product support obligations.

Income from operations as a percentage of revenue decreased ~~$24.8 million~~to 8.7% in ~~the first three quarters of 2016~~Q1 2017 compared to ~~the first three quarters of 2015~~21.2% in Q1 2016 primarily due to lower gross margins and the increase in research and development and selling, general and administrative expenses ~~which we~~as a percentage of revenue. We expect ~~will~~research and development and selling, general and administrative expenses to continue to grow. ~~The increase in operating expenses was partially offset by higher gross profit.~~

Our effective tax rate was ~~24.9%~~30.8% in ~~the first three quarters of 2016,~~Q1 2017, compared to ~~20.9%~~24.5% in ~~the first three quarters of 2015.~~Q1 2016. The variance from the U.S. federal statutory tax rate of 35% was primarily attributable to the mix of earnings in jurisdictions with lower statutory tax rates than the U.S. federal statutory tax rate, such as in Singapore and the United Kingdom, partially offset by the discrete tax impact ~~associated with~~of $150 million from the ~~investments in our consolidated variable interest entities.~~gain on the deconsolidation of GRAIL. Our future effective tax rate may vary from the U.S. federal statutory tax rate due to the mix of earnings in tax jurisdictions with different statutory tax rates and the other factors discussed in the risk factor “We are subject to risks related to taxation in multiple jurisdictions” in Part I Item 1A of our Annual Report on Form 10-K for the fiscal year ended January ~~3, 2016.~~1, 2017. We anticipate that our effective tax rate will trend lower than the U.S. federal statutory tax rate in the future due to the portion of our earnings that will be subject to lower statutory tax rates.

Cash, cash equivalents, and short-term investments were $~~1.5~~1.8 billion as of ~~October~~April 2, ~~2016.~~2017, of which approximately $679 million was held by our foreign subsidiaries.

Other income, net in Q1 2017 primarily consists of a $453 million gain recorded on the deconsolidation of GRAIL. Other income, net in Q1 2016 primarily consisted of net foreign exchange gains and losses.

Interest income increased in Q1 2017 compared to Q1 2016 as a result of higher yields on our investments and higher savings and money market balances. Interest expense consisted primarily of accretion of discount on our convertible senior notes. ~~The decrease in interest expense in Q3 2016 compared to Q3 2015 was due to a lower outstanding principal balance on the 2016 Notes, which matured in March 2016.~~

~~Other (expense) income, net in Q3 2015 primarily consists of a $3.5 million loss on extinguishment of debt. There was no such loss in the same period of the current year.~~

~~YTD 2016 vs. YTD 2015~~

Interest expense consisted primarily of accretion of discount on our convertible senior notes. The decrease in interest expense in the first three quarters of 2016 compared to the first three quarters of 2015 was due to a lower outstanding principal balance on the 2016 Notes, which matured in March 2016.

~~Cost-method investment gain, net, during the first three quarters of 2015 consisted primarily of a gain on the sale of a cost-method investment.~~

Other (expense) income, net, in the first three quarters of 2016 primarily consisted of net foreign exchange gains and losses. Other (expense) income, net, in the first three quarters of 2015 consists of a $3.5 million loss on extinguishment of debt and net foreign exchange gains and losses.

Liquidity and Capital Resources

At ~~October~~April 2, ~~2016~~2017, we had approximately $~~794.7~~981 million in cash and cash equivalents, of which approximately ~~$349.0~~$362 million ~~were~~was held by our foreign subsidiaries. Cash and cash equivalents ~~held by our consolidated VIEs as of October 2, 2016 were $103.6 million. Cash and cash equivalents~~ increased by ~~$25.9~~$246 million from January ~~3, 2016,~~1, 2017, due to the factors described in the “Cash Flow Summary” below. Our primary source of liquidity, other than our holdings of cash, cash equivalents and investments, has been cash flows from operations. Our ability to generate cash from operations provides us with the financial flexibility we need to meet operating, investing, and financing needs. It is our intention to indefinitely reinvest all current and future foreign earnings in foreign subsidiaries.

Historically, we have liquidated our short-term investments and/or issued debt and equity securities to finance our business needs as a supplement to cash provided by operating activities. As of ~~October~~April 2, ~~2016~~2017, we had $~~741.6~~797 million in short-term investments. Short-term investments held by our foreign subsidiaries as of ~~October~~April 2, ~~2016~~2017 were approximately ~~$256.2~~$317 million. Our short-term investments include marketable securities consisting of U.S. government-sponsored entities, corporate debt securities, and U.S. Treasury securities.

During the first three quarters of 2016, $75.5 million in principal of the 2016 Notes were converted. The 2016 Notes became convertible on April 1, 2014 through, and including, March 11, 2016. All 2016 Notes were converted by March 11, 2016. The convertible senior notes due 2019 and 2021 were not convertible as of October 2, 2016.

We anticipate that our current cash, cash equivalents and short-term investments, together with cash provided by operating activities are sufficient to fund our near term capital and operating needs for at least the next 12 months. Operating needs include the planned costs to operate our business, including amounts required to fund working capital and capital expenditures. Our primary short-term needs for capital, which are subject to change, include:

support of commercialization efforts related to our current and future products, including expansion of our direct sales force and field support resources both in the United States and abroad;

acquisitions of equipment and other fixed assets for use in our current and future manufacturing and research and development facilities;

the continued advancement of research and development efforts;

potential strategic acquisitions and investments;

potential early repayment of debt obligations as a result of conversions;

the expansion needs of our facilities, including costs of leasing and building out additional facilities; and

repurchases of our outstanding common stock.

AsOur convertible senior notes due 2019 and 2021 were not convertible as of ~~October~~April 2, ~~2016, $236.9~~2017.

During Q1 2017, we used $101 million ~~remains under an authorized~~to repurchase our outstanding shares, completing the stock repurchase ~~program.~~program authorized by our Board of Directors. On May 4, 2017, the Board of Directors authorized an additional share repurchase program to repurchase $250 million of outstanding common stock. The repurchases may be completed under a 10b5-1 plan or at management’s discretion.

Certain noncontrolling Helix investors may require Illumina to redeem all noncontrolling interests in cash at the then approximate fair market value. Such redemption right is exercisable at the option of certain noncontrolling interest holders after January 1, 2021, provided that a bona fide pursuit of the sale of Helix has occurred and an initial public offering of Helix has not been completed. The fair value of the redeemable noncontrolling interests related to Helix as of ~~October~~April 2, ~~2016~~2017 was ~~$33.1~~$59 million.

~~On April 14, 2016, we announced~~We have $89 million remaining in our capital commitment to ~~invest $100.0 million in a new~~the venture capital investment fund established by Nicholas Naclerio, Ph.D., our former Senior Vice President, Corporate and Venture Development. The capital commitment is callable over ten years, and up to $40.0 million can be drawn down duringas of April 2, 2017.

On February 28, 2017, GRAIL completed the ~~first year. During the nine months ended October 2, 2016, the Company transferred $3.2 million~~initial close of its ~~cost-method investments~~Series B preferred stock financing and repurchased a portion of our interest for $278 million, reducing our ownership interest to 19%. As discussed in note 2 of the Notes to the ~~Fund and contributed $4.4 million in cash.~~Condensed Consolidated Financial Statements, our purchase obligation of GRAIL’s Series B preferred shares is $14 million.

We expect that our revenue and the resulting operating income, as well as the status of each of our new product development programs, will significantly impact our cash management decisions.

Our future capital requirements and the adequacy of our available funds will depend on many factors, including:

our ability to successfully commercialize and further develop our technologies and create innovative products in our markets;

scientific progress in our research and development programs and the magnitude of those programs;

competing technological and market developments; 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.

Off-Balance Sheet Arrangements

We do not participate in any transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. During the first ~~three quarters~~quarter of ~~2016,~~2017, we were not involved in any “off-balance sheet arrangements” within the meaning of the rules of the Securities and Exchange Commission.

Critical Accounting Policies and Estimates

In preparing our condensed consolidated financial statements, we make estimates, assumptions and judgments that can have a significant impact on our net revenue, operating income and net income, as well as on the value of certain assets and liabilities on our balance sheet. We believe that the estimates, assumptions and judgments involved in the accounting policies described in Management’s Discussion and Analysis of Financial Condition and Results of Operations in Item 7 of our Annual Report on Form 10-K for the fiscal year ended January ~~3, 2016~~1, 2017 have the greatest potential impact on our financial statements, so we consider them to be our critical accounting policies and estimates. ~~There~~Other than the adoption of ASU 2016-09, Compensation - Stock Compensation (Topic 718) as described in note 2 of the Notes to the Condensed Consolidated Financial Statements provided in this Quarterly Report of Form 10-Q, there were no material changes to our critical accounting policies and estimates during ~~the first three quarters of 2016.~~Q1 2017.

Recent Accounting Pronouncements

For summary of recent accounting pronouncements applicable to our condensed consolidated financial statements, see note “1. Summary of Significant Accounting Policies” in Part I, Item 1, Notes to Condensed Consolidated Financial Statements, which is incorporated herein by reference.

Consideration Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements that involve risks and uncertainties, such as statements of our plans, strategies, objectives, expectations, intentions, and adequacy of resources. Words such as “anticipate,” “believe,” “continue,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” or similar words or phrases, or the negatives of these words, may identify forward-looking statements, but the absence of these words does not necessarily mean that a statement is not forward looking. Examples of forward-looking statements include, among others, statements regarding the integration of our acquired technologies with our existing technology, the commercial launch of new products, the entry into new business segments or markets, and the duration which our existing cash and other resources is expected to fund our operating activities.

Forward-looking statements are subject to known and unknown risks and uncertainties and are based on potentially inaccurate assumptions that could cause actual results to differ materially from those expected or implied by the ~~forward-looking~~forward-

looking statements. Among the important factors that could cause actual results to differ materially from those in any forward-looking statements include the following:

our ability to develop and commercialize our instruments and consumables, to deploy new products, services, and applications, and expand the markets for our technology platforms;

our ability to manufacture robust instrumentation and consumables;

our ability to identify and integrate acquired technologies, products, or businesses successfully;

our expectations and beliefs regarding prospects and growth for the business and its markets;

the assumptions underlying our critical accounting policies and estimates;

our assessments and estimates that determine our effective tax rate;

our assessments and beliefs regarding the outcome of pending legal proceedings and any liability that we may incur as a result of those proceedings;

uncertainty, or adverse economic and business conditions, including as a result of slowing or uncertain economic growth in the United States or worldwide; and

other factors detailed in our filings with the SEC, including the risks, uncertainties, and assumptions described in Item 1A of our Annual Report on Form 10-K for the fiscal year ended January ~~3, 2016~~1, 2017, or in information disclosed in public conference calls, the date and time of which are released beforehand.

The foregoing factors should be considered together with other factors detailed in our filings with the Securities and Exchange Commission, including our most recent filings on Forms 10-K and 10-Q, or in information disclosed in public conference calls, the date and time of which are released beforehand. We undertake no obligation, and do not intend to update these forward-looking statements, to review or confirm analysts’ expectations, or to provide interim reports or updates on the

progress of the current financial quarter. Accordingly, you should not unduly rely on these forward-looking statements, which speak only as of the date of this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There were no substantial changes to our market risks in the ~~nine~~three months ended ~~October~~April 2, ~~2016~~2017, when compared to the disclosures in Item 7A of our Annual Report on Form 10-K for the fiscal year ended January ~~3, 2016~~1, 2017.

Item 4. Controls and Procedures.

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 U.S. generally accepted accounting principles. We also maintain internal controls and procedures to ensure that we comply with applicable laws and our established financial policies.

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

During ~~Q3 2016,~~Q1 2017, we continued to monitor and evaluate the operating effectiveness of key ~~controls related to process enhancements arising out of our enterprise resource planning system implementation in 2015.~~controls. There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that materially affected or are reasonably likely to materially affect internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings.

We are involved in various lawsuits and claims arising in the ordinary course of business, including actions with respect to intellectual property, employment, and contractual matters. In connection with these matters, we ~~assesses,~~assess, on a regular basis, the probability and range of possible loss based on the developments in these matters. A liability is recorded in the financial statements if it is believed to be probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable results could occur, assessing contingencies is highly subjective and requires judgments about future events. We regularly review outstanding legal matters to determine the adequacy of the liabilities accrued and related disclosures. The amount of ultimate loss may differ from these estimates. Each matter presents its own unique circumstances, and prior litigation does not necessarily provide a reliable basis on which to predict the outcome, or range of outcomes, in any individual proceeding. Because of the uncertainties related to the occurrence, amount, and range of loss on any pending litigation or claim, we are currently unable to predict their ultimate outcome, and, with respect to any pending litigation or claim where no liability has been accrued, to make a meaningful estimate of the reasonably possible loss or range of loss that could result from an unfavorable outcome. In the event that opposing litigants or claims ultimately succeed at trial and any subsequent appeals on their claims, any potential loss or charges in excess of any established accruals, individually or in the aggregate, could have a material adverse effect on our business, financial condition, results of operations, and/or cash flows in the period in which the unfavorable outcome occurs or becomes probable, and potentially in future periods.

Item 1A. Risk Factors.

Our business is subject to various risks, including those described in Item 1A of our Annual Report on Form 10-K for the fiscal year ended January ~~3, 2016~~1, 2017, which we strongly encourage you to review. There have been no material changes from the risk factors disclosed in Item 1A of our Form 10-K.
