NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. ORGANIZATION AND DESCRIPTION OF BUSINESS

GRAIL, Inc. (“GRAIL” or the “Company”) was incorporated in the State of Delaware in September 2015 and began operations as a stand-alone entity in February 2016. GRAIL is a healthcare company focused on developing technologies for early cancer detection. The Company is headquartered in Menlo Park, California.

Since inception, the Company has incurred losses from operations. The Company incurred losses from operations of $81.3 million and $64.6 million for the three months ended September 30, 2020 and 2019, respectively, and $220.4 million and $188.0 million for the nine months ended September 30, 2020 and 2019, respectively. The Company had an accumulated deficit of $1.5 billion as of September 30, 2020. The Company has not yet launched a commercial product and may never develop a product that will generate revenues, including in amounts that will be sufficient to fund operations. Accordingly, the Company has been dependent on its ability to raise capital through equity issuances.

The Company had $634.6 million of cash, cash equivalents, and marketable securities at September 30, 2020. Based on the Company’s business plans, management believes that this is sufficient to meet its obligations for at least 12 months from the issuance date of these unaudited condensed consolidated financial statements.

Illumina Transaction

On September 20, 2020, the Company entered into an Agreement and Plan of Merger with Illumina, Inc. (“Illumina”), SDG Ops, Inc., a wholly-owned subsidiary of Illumina, and SDG Ops, LLC, a Delaware limited liability company and a wholly-owned subsidiary of Illumina (the “Merger Agreement”) pursuant to which Illumina will acquire the Company for $8 billion upon closing of the transaction, consisting of $3.5 billion in cash and $4.5 billion in shares of Illumina common stock, subject to a collar. In addition, stockholders of the Company will receive contingent value rights (“CVR”) to receive future payments representing a pro rata portion of certain revenues related to the Company over a twelve-year period. This will reflect a 2.5% payment right to the first $1 billion of revenue and a 9% payment right to revenues exceeding $1 billion during the same period each year for 12 years. Illumina will offer Company stockholders the option to receive additional cash and/or stock consideration, in an amount to be determined prior to closing, in lieu of the CVR. If the transaction is not consummated on or prior to December 20, 2020, the Merger Agreement provides that Illumina will make cash payments to the Company in the amount of $35 million each month prior to the closing date of the transaction, commencing on December 21, 2020 until the earlier of (1) the closing date of the transaction or (2) the termination of the transaction (“Continuation Payments”).

Completion of the transaction is subject to terms and conditions set forth in the Merger Agreement, including (i) the receipt of required approvals from Company’s stockholders, (2) the receipt of required regulatory approvals, including the expiration or termination of the waiting period (and any extension thereof) under the Hart-Scott-Rodino Act, as amended (the “HSR Act”), (3) the absence of any law, whether temporary, preliminary or permanent, which is then in effect and has the effect of enjoining, restraining, prohibiting or otherwise preventing consummation of the transactions, (4) the effectiveness of the Registration Statement to be filed by Illumina (together with all amendments thereto, the “Registration Statement”), pursuant to which the shares of Illumina common stock to be issued in connection with the transactions will be registered with the Securities and Exchange Commission, and

9

(5) the authorization for listing on NASDAQ of the shares of Illumina common stock to be issued in connection with the transactions. The United States Federal Trade Commission (“FTC”) has been notified about the Merger and it is under review by the FTC.

No assurance can be given that the required regulatory approvals will be obtained or that the required conditions to closing will be satisfied, and, even if all such approvals are obtained and the conditions are satisfied, no assurance can be given as to the terms, conditions and timing of the approvals. The Merger Agreement contains certain termination rights for each of the Company and Illumina, including a termination right for each of the Company and Illumina if the consummation of the merger does not occur on or before September 20, 2021, subject to a three-month extension for certain limited purposes in connection with obtaining certain required regulatory clearances. Upon termination of the Merger Agreement under specified circumstances, Illumina would be required to pay the Company a termination fee of $300 million and make an additional $300 million investment in the Company in exchange for shares of non-voting Company preferred stock, subject to certain terms and conditions. In the event that the Merger Agreement is terminated, with respect to all Continuation Payments in excess of $315 million, Illumina will make an investment in the Company in exchange of shares of non-voting Company preferred stock, subject to certain terms and conditions.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements as of September 30, 2020 and December 31, 2019 and for the three and nine months ended September 30, 2020 and 2019 include the accounts of GRAIL, Inc. and its wholly-owned subsidiaries. The condensed consolidated financial statements are prepared in accordance with United States Generally Accepted Accounting Principles (U.S. GAAP). All intercompany balances and transactions have been eliminated on consolidation.

Unaudited Condensed Consolidated Financial Statements

The condensed consolidated balance sheet as of September 30, 2020 and the condensed consolidated statements of operations, of comprehensive loss, of cash flows, and of redeemable convertible preferred stock and stockholders’ deficit for the three and nine months ended September 30, 2020 and 2019 are unaudited. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect, in the opinion of management, all adjustments of a normal and recurring nature that are necessary for the fair statement of the Company’s financial position as of September 30, 2020 and its results of operations and cash flows for the three and nine months ended September 30, 2020 and 2019. The financial data and the other financial information disclosed in these notes to the condensed consolidated financial statements related to the three and nine months ended September 30, 2020 and 2019 are also unaudited. The condensed consolidated results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the results to be expected for the year ending December 31, 2020 or for any other future annual or interim period. The condensed consolidated balance sheet as of December 31, 2019 included herein was derived from the audited consolidated financial statements as of that date, but does not include all disclosures required by U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2019.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts of assets and

10

liabilities, disclosure of contingent assets and liabilities, and the reported amounts of expenses in the condensed consolidated financial statements and accompanying notes. On an ongoing basis, management evaluates its estimates, including those related to accrued clinical studies and research and development expenses, stock-based compensation expense, useful lives of intangible assets and property and equipment, determination of incremental borrowing rate for operating leases, and the provision for income taxes.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, and marketable securities.

Substantially all the Company’s cash and cash equivalents are deposited in accounts with four accredited financial institutions that management believes are of high-credit quality. Such deposits have and will continue to exceed federally insured limits. The Company has not experienced any losses on its cash deposits.

The Company’s investment policy limits investments to certain types of securities issued by the U.S. government and its agencies and institutions with investment-grade credit ratings and places restrictions on maturities and concentration by type and issuer. The Company is exposed to credit risk in the event of a default by the financial institutions holding its cash, cash equivalents, and marketable securities, and by issuers of marketable securities to the extent recorded on the consolidated balance sheets. As of September 30, 2020, the Company had no off-balance sheet concentrations of credit risk.

Risks and Uncertainties

The Company is in the research and discovery stage and may never develop a product that will generate revenues, including in amounts that will be sufficient to fund operations. The market for which the Company is developing products is highly competitive and rapidly changing. Difficulties or delays in the Company’s clinical studies, delays in planned commercial launch of the Company’s products, potential complications with the Company’s sole suppliers, complex regulatory regimes, regulatory issues and other factors could negatively impact the Company’s operating results.

The Company may need to raise additional equity or debt financing to fund future operations that may not be available at terms acceptable to the Company, if at all. If the Company does not successfully commercialize its products in development, it will be unable to generate revenue from product sales or achieve profitability.

In December 2019, a novel strain of coronavirus (COVID-19) was reported in Wuhan, China and has since become a global pandemic. The COVID-19 pandemic poses the risk that the Company, its personnel and other partners may be prevented from conducting business activities for an indefinite period of time, including due to spread of the disease within these groups or due to shutdowns that may be requested or mandated by governmental authorities. The ongoing COVID-19 pandemic has delayed anticipated completion of the Company’s clinical studies, as the Company had to suspend enrollment of the studies during the nine months ended September 30, 2020. As of the date of issuance of these unaudited condensed consolidated financial statements, the Company is not aware of any specific event or circumstance related to COVID-19 that would require it to update its estimates or judgments or adjust the carrying value of its assets or liabilities. Actual results could differ from those estimates and any such differences may be material to the consolidated financial statements. The extent to which the coronavirus outbreak may materially impact the Company’s financial condition, liquidity, or results of operations is uncertain.

11

The Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) was enacted by the United States on March 27, 2020. The Company is continuing to analyze the impact of the CARES Act. The CARES Act did not have a material impact on the Company’s provision for income taxes for the three and nine months ended September 30, 2020.

Significant Accounting Policies

There have been no material changes in the Company’s accounting policies from those disclosed in the audited consolidated financial statements and related notes thereto as of and for the year ended December 31, 2019.

Recent Accounting Pronouncements

Accounting Standards Update (ASU) 2016-13 and 2020-03, collectively implemented as Financial Accounting Standards Board (FASB) Accounting Standards Codification 326, Financial Instruments—Credit Losses (Topic 326), provides amended guidance for measuring current expected credit loss. In June 2016, FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326). ASU 2016-13 requires measurement and recognition of expected credit losses for financial assets. On January 1, 2020, the Company adopted Topic 326 using a modified retrospective approach, which had no material impact on the Company’s condensed consolidated financial statements. In March 2020, the FASB issued ASU 2020-03, Codification Improvements to Financial Instruments, which makes improvements to financial instruments guidance. The adoption of this ASU did not have a material impact on the Company’s condensed consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The ASU improves the effectiveness of fair value measurements disclosures and modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, based on the concepts in the FASB Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements, including the consideration of costs and benefits. On January 1, 2020, the Company adopted Topic 820. The adoption of this ASU did not have a material impact on the Company’s condensed consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. ASU 2018-15 amended guidance to align the accounting for costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing costs associated with developing or obtaining internal-use software. Capitalized implementation costs must be expensed over the term of the hosting arrangement and presented in the same line item in the statement of income as the fees associated with the hosting element (service) of the arrangement. The Company adopted ASU 2018-15 as of January 1, 2020 on a prospective basis, and the adoption of this ASU did not have a material impact on the Company’s condensed consolidated financial statements.

As of September 30, 2020 and December 31, 2019, some of the Company’s marketable securities were in an unrealized loss position. The Company held a total of 12 and 23 positions, which were in an unrealized loss position as of September 30, 2020 and December 31, 2019, respectively. The Company determined that no credit losses exist as of September 30, 2020 and December 31, 2019 because the change in market value for those securities related primarily to interest rate shifts rather than significant changes in the underlying credit quality of the securities that it holds. The Company has the ability to hold all marketable securities that have been in a continuous loss position until maturity or recovery.

The Company’s short-term marketable securities have an effective maturity date of less than 12 months, and the long-term marketable securities have an effective maturity date of greater than 12 months and less than 16 months.

NOTE 6. LEASES

The Company has entered into operating and finance leases for facilities and research and development equipment. As of September 30, 2020, the Company does not have any remaining finance leases. Operating leases have remaining lease terms which range from 2 years to 13 years, and often include one or more options to renew. These renewal terms can extend the lease term from 1 to 5 years and are included in the lease term when it is reasonably certain that the Company will exercise the option. One lease provides the option to terminate the lease under certain conditions with three months’ notice. The Company does not expect to exercise this termination option. The exercise of lease renewal and termination options is at the Company’s sole discretion. The Company also has variable lease payments that are primarily comprised of common area maintenance and utility charges.

During the nine months ended September 30, 2019, in connection with the decision to exit its Hong Kong facility, the Company recorded impairment charges of $1.3 million in research and development expenses relating to operating lease right-of-use assets (ROU assets). No impairment charges were recorded for the three months ended September 30, 2019.

In June 2020, the Company entered into a new agreement to lease approximately 200,000 square feet of laboratory and office space in North Carolina, which commenced in September 2020 for a term of 12.5 years with three five-year renewal options. Upon commencement, the Company recognized an operating lease ROU asset of $20.2 million and an operating lease liability of $20.2 million. The total estimated aggregate base rent payments, excluding the renewal options and any tenant improvement allowances, for the North Carolina laboratory and office space are $86.6 million.

As of September 30, 2020, the Company does not have additional operating and finance leases that have not yet commenced.

NOTE 7. COMMITMENTS AND CONTINGENCIES

See Note 6 for a summary of the Company’s lease commitments. As of September 30, 2020, the Company’s future commitments over the next five years and thereafter were as follows:

	Minimum Royalties		Purchase Commitments		Total
			(in thousands)

Thereafter		6,750		—		6,750
Total commitments	$	10,045	$	3,021	$	13,066

(*) Excluding the nine months ending September 30, 2020.

Minimum Royalty Commitments

The Company has certain minimum royalty commitments under licensing agreements related to its research efforts.

Purchase Commitments

The Company has open purchase orders primarily related to the purchase of laboratory supplies in the normal course of business.

Contingencies

The Company responds to claims arising in the ordinary course of business. If necessary, the Company will accrue estimates of the amounts it expects to pay upon resolution of such matters, and such amounts will be included in other current liabilities. Should the Company not be able to secure the terms it expects, these estimates may change and will be recognized in the period in which they are identified.

Legal Matters

The Company is subject to various claims, complaints, and legal actions that arise from time to time. The Company does not believe it is a party to any currently pending or threatened legal proceedings that will result in a material adverse effect on its business. There can be no assurance that existing or future legal proceedings arising in the ordinary course of business or otherwise will not have a material adverse effect on the Company’s business, financial position, results of operations, or cash flows.

Indemnification

The Company has agreed to indemnify its directors and officers for certain events or occurrences while the director or officer is, or was serving, at the Company’s request in such capacity. The

19

indemnification period covers all pertinent events and occurrences during the director’s or officer’s service. The maximum potential amount of future payments the Company could be required to make under the applicable indemnification agreements is not specified in the agreements; however, the Company has director and officer insurance coverage that reduces its exposure and enables the Company to recover a portion of any future amounts paid. The Company believes the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to the Company’s technology. The term of these indemnification agreements is generally perpetual after the execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these arrangements is not determinable. The Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal.

NOTE 8. COMMON STOCK

The Company has two classes of common stock: Class A and Class B. The voting rights per share of Class A and Class B are 1:1 and 10:1, respectively. Common stockholders are entitled to dividends when and if declared by the board of directors subject to the prior rights of the preferred stockholders. As of September 30, 2020, no dividends have been declared.

During the fourth quarter of 2019, the Company issued 31,323,413 shares of Series D redeemable convertible preferred stock for gross proceeds of $160.0 million, less $0.2 million of issuance costs. The Series D redeemable convertible preferred stock has substantially similar terms as the Company’s Series A, B, and C redeemable convertible preferred stock except that it has a liquidation preference of $5.108 per share.

During the nine months ended September 30, 2020, the Company issued 45,420,423 additional shares of Series D redeemable convertible preferred stock for gross proceeds of $232 million less $0.1 million of issuance costs. No additional shares of Series D redeemable convertible preferred stock were issued during the three months ended September 30, 2020. The Series D redeemable convertible preferred stock has substantially similar terms as the Company’s Series A, Series B and Series C redeemable convertible preferred stock except that it has a liquidation preference of $5.108 per share, respectively.

Redemption

As of September 30, 2020 and December 31, 2019, the Company classified the convertible preferred stock as redeemable on the consolidated balance sheets. Upon the occurrence of certain change-in-control events that may be outside the Company’s control, including liquidation, sale, or transfer of the Company, holders of the convertible preferred stock could cause a redemption of their stock for cash. The preferred stock does not have a mandatory redemption date.

Conversion

Each share of preferred stock is convertible, at the option of the holder, according to a conversion ratio, which is subject to adjustment for dilutive share issuances as described in the next paragraph.

21

The total number of shares of common stock into which the preferred stock may be converted is determined by dividing the then-applicable conversion price by the initial conversion price. The preferred stock automatically converts into shares of Class A common stock at the then-applicable conversion price in the event of an underwritten public offering of shares of common stock with aggregate gross proceeds of no less than $150 million (Qualifying IPO), provided that, prior to April 17, 2022 (24 months after the Series D extension closing), such automatic conversion shall also require either (i) the per share price of the Qualifying IPO to be at least $5.108 per share (i.e., the Series D preferred stock original issue price) or (ii) the vote of the holders of a majority of the combined Series C and D preferred stock. The preferred stock also automatically converts into shares of Class A common stock at the then-applicable conversion price upon the vote of a majority of the holders of preferred stock and, if prior to April 17, 2022, the vote of the holders of two-thirds of the combined Series C and D preferred stock shall also be required. As of September 30, 2020, each share of Series A, B, C, and D preferred stock was convertible into one share of Class A common stock.

Subject to certain exceptions, including issuances of shares to employees or consultants pursuant to a stock option plan approved by the board of directors and issuances of shares to lenders or strategic partners or in connection with the acquisition of a company or technology, in each case approved by the board of directors, the conversion price of each applicable series of preferred stock is subject to adjustment to prevent dilution in the event that the Company issues additional shares at a purchase price less than the then-applicable conversion price.

Dividends

Any dividends paid in any fiscal year will be paid among the holders of redeemable convertible preferred stock and common stock then outstanding based on preferences and on an if-converted basis. Dividends are noncumulative, and none were declared as of September 30, 2020 or December 31, 2019.

Voting

Each share of redeemable convertible preferred stock is entitled to the number of votes equal to the number of shares of Class A common stock into which such shares could be converted. Holders of redeemable convertible preferred stock and common stock vote as a single class.

Liquidation Preference

In the event of any liquidation, dissolution or winding up of the Company, either voluntary or involuntary, including a merger, acquisition, or sale of assets where the holders of common stock and preferred stock own less than a majority of the resulting voting power of the surviving entity (Liquidation Transaction), the holders of preferred stock will receive in preference to the holders of common stock, an amount per share equal to the liquidation preference, plus any accrued but unpaid dividends. After payment of the liquidation preference to the holders of the preferred stock, the remaining assets of the Company are available for distribution to the holders of common stock on a pro rata basis. The vote of a majority of the holders the preferred stock can waive the liquidation preference; provided that, prior to April 17, 2022, the vote of the holders of two-thirds of the combined Series C and D preferred stock shall also be required to waive such liquidation preference. These liquidation features cause the Series A, B, C, and D preferred stock to be classified as mezzanine equity rather than as a component of stockholders’ deficit.

In October 2017, the Company entered into a transition agreement with the vice chairperson of the board of directors. Under the transition agreement, the individual was eligible to receive up to $130.0 million in incentive awards. During the nine months ended September 2020, the transition agreement was modified.

27

The incentive awards for the vice chairperson of the board of directors are granted subject to the respective individual’s continued service to the Company. The awards are earned upon the satisfaction of certain performance-based conditions based on cumulative net revenues in any period of four consecutive quarters.

The above incentive awards for the vice chairperson of the board of directors will be paid, at the Company’s election, in fully vested shares of Class B common stock (or securities into which the Class B common stock has previously been converted) or in cash. The dollar value of these incentive awards is based on the achievement of the performance-based conditions described above. The number of shares is variable based on the per-share valuation at the time the performance-based conditions are met. Accordingly, these awards are accounted for as liability-classified awards, and, once the related performance-based conditions are deemed to be probable, the liability will be remeasured at fair value on each reporting date until the awards vest.

As of September 30, 2020, the Company had not recognized any compensation expense associated with these awards as the achievement of the performance-based condition was not deemed to be probable.

As the Company was in a net loss position for all periods presented, basic net loss per share is the same as diluted net loss per share because the inclusion of potential shares of common stock would have been anti-dilutive. The following common stock equivalents were therefore excluded from the computation of diluted net loss per share for the periods presented:

	As of September 30,
	2020		2019
Redeemable convertible preferred stock (on an if-converted basis)		534,145,027		457,401,191
Options to purchase common stock and restricted stock units		126,600,727		101,381,330
Shares subject to repurchase		570,925		8,303,896
Total		661,316,679		567,086,417
