Please respond to this letter by providing the requested information and either submitting an amended draft registration statement or publicly filing your registration statement on EDGAR. If you do not believe a comment applies to your facts and circumstances or do not believe an amendment is appropriate, please tell us why in your response. After reviewing the information you provide in response to this letter and your amended draft registration statement or filed registration statement, we may have additional comments. Unless we note otherwise, any references to prior comments are to comments in our January 8, 2024 letter. Amendment No. 1 to Draft Registration Statement on Form 10-12B Summary, page 2 1. We note your revised disclosure in response to previous comment 2 and re-issue the comment in part. If true, please clarify that Galleri's clinical validation is the view or belief of management based on the results of your clinical studies completed to date or otherwise revise your statement so that it is clear that the Galleri test has not been approved by the FDA or an equivalent foreign regulator. 2. We note your revised disclosure in response to comment 3. Please address the following: You disclose that, based on data from your CCGA and PATHFINDER studies, Robert Ragusa FirstName LastNameRobert Ragusa GRAIL, LLC Comapany26, February NameGRAIL, 2024 LLC February Page 2 26, 2024 Page 2 FirstName LastName Galleri "can predict with high accuracy (88%) the specific organ or tissue type where the cancer signal originated." Please revise your disclosure to disclose the data underlying your "88%" high accuracy rate, and briefly explain, as you do on page 127, how this measure relates to the PPVs of 43% and 44% noted on page 4 related to the same studies. You disclose that "[a]pproximately 67% of cancer deaths result from cancers that have no recommended screening guidelines, based on our own estimates using 2022 American Cancer Society Facts and Figures." Please disclose the relevant "facts and figures" supporting your estimate. Make conforming changes throughout your filing where you cite to your estimates based on these facts and figures, including the description of your business on page 122 where you disclose that "we estimate that asymptomatic individuals undertaking a standard of care screening test are many times (2-24x depending on cancer type) more likely to have a different type of cancer than the cancer type for which they are being screened," and "single-cancer screening tests are also unlikely to be developed for detecting less common cancers." We note your disclosure that "we estimate that adding Galleri to these five standard of care single-cancer screening tests (breast, cervical, colorectal, lung cancer, and prostate) could detect many more cancers at an earlier stage and potentially avert approximately 100,000 deaths per year in the United States as measured by five-year survival." Please provide the basis for your statement. You disclose that "a recent analysis published in Data in September 2017 estimated that diagnosing cancer early could result in an estimated $26 billion in annual cost- savings in the United States." Please identify the article or analysis. In addition, given your characterization of this statistic as "recent," please revise your disclosure to provide a more current source or tell us why you are unable to do so. Your revised disclosure on page 5 includes a statement that "Data published in The Lancet Oncology showed that, in a symptomatic patient population, our methylation technology was able to detect many cancer types and identify where the cancer signal origin was located in the body with high accuracy (91%)." Please disclose the source of the data published in the Lancet and describe the data supporting the 91% accuracy rate. Generally, where you reference an article or analyses in a publication, please identify the specific article or analyses. For example, we note your disclosures on page 121 referencing "an article" in JAMA Oncology and "an article" in the Journal of the National Comprehensive Cancer Network. 3. We note your response and revised disclosure in response to previous comment 8 and re- issue the comment in part. In addition to providing your anticipated timeline for launching the DAC test, please also describe the status of your development efforts.

We note the statements in your response to previous comment 10 that "risks related to the regulatory proceedings are fundamentally borne by Illumina" and that "The Company expects that future costs associated with regulatory proceedings will be limited because the Separation and Distribution is anticipated to expedite resolution of these regulatory proceedings and the Company does not anticipate being a separate party to ongoing regulatory proceedings after the spin-off transaction."

We note your response to comment 16, including that "outside advisors provided information and analyses to assist the Illumina Board, and the committee thereof, understand the range of potential divestment transactions, including regarding their respective structures, timing and process and legal considerations." Given that the information and analyses of the outside advisors appears to have aided the Illumina board Robert Ragusa FirstName LastNameRobert Ragusa GRAIL, LLC Comapany26, February NameGRAIL, 2024 LLC February Page 4 26, 2024 Page 4 FirstName LastName in its consideration of strategic alternatives and ultimate determination to effect the spin- off, please provide a more detailed legal analysis describing why the reports and recommendations provided by these outside advisors were not material to the board's decision.
