Figure 1. Our Toolbox, page 2 4. Please increase the font size of the text within the table. 5. Please remove the statement claiming your base editors will accelerate therapeutic development, as it appears speculative. Figure 2: Therapeutic Translation., page 4 6. Please revise this graphic to separate the "Clinical" column into Phase I, Phase II and Phase III to clearly represent what development stages must be completed prior to commercialization of your therapeutic candidates. In addition, please combine your columns labeled "lead optimization" and "IND-enabling" into one preclinical development column. 7. We note the inclusion of therapeutic candidates for renal disease and autoimmune/immuno-oncology in your pipeline table. Given the limited disclosure related to these programs, please explain why they are sufficiently material to your business to warrant inclusion in your pipeline table. If they are material, please expand your disclosure in the Business section to provide a more fulsome discussion of these programs, including a description of development activities conducted. Alternatively, remove any programs that are not currently material from your pipeline table on pages 4 and 158. 8. We note that the gene for cardiovascular disease is "undisclosed." If this gene has been determined, please revise your table, to identify the gene and describe this program. Critical Accounting Policies and Significant Judgments and Estimates, page 116 9. We note the following disclosure from page 223: "The grant date fair value of all awards made under our 2023 Plan and all other cash compensation paid by us to any non- employee director in any calendar year for services as a non-employee director shall not exceed $ ; provided, however, that such amount shall be $ for the calendar year in which the applicable non-employee director is initially elected or appointed to the board of directors."

Please remove references to your genome editing systems potentially being "best-in-class" and "first-in-class" as it does not appear that your platform has resulted in any FDA approved therapies and future approved therapies are speculative. Moderna Strategic Collaboration and License Agreement, page 181 11. We note your disclosure stating you are eligible to receive royalties ranging from a mid- single digit to a "low double-digit" percentage of annual net sales from licensed products. As drafted, it is unclear if "low double-digit" refers to a range within ten percentage points of a mid-single digit percentage. Please revise your disclosure to limit the royalty range to ten percentage points. 12. Given your disclosure that you received a non-refundable upfront payment of $40.0 million, a $5.0 million payment for the first year of research costs, Moderna's obligation to reimburse you for up to $5.0 million in annual research and development costs, your eligibility to receive development, regulatory and sales milestone payments and royalty payments, explain the statement that you will work with Moderna on the co-development and commercialization of products with respect to the DT Co-Co program and share costs and profits equally.

Will the royalty payments to Metagenomi be considered part of its share in the profits? Our License and Collaboration Agreements, page 181 13. For each agreement discussed in this section, please disclose the aggregate amounts paid to date and the aggregate amount of remaining potential payments under each agreement.
