Other Events.

As previously disclosed, on November 14, 2023, Graphite Bio, Inc., a Delaware corporation (“Graphite”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among Graphite, Generate Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Graphite (“Merger Sub”), and Lenz Therapeutics, Inc., a Delaware corporation (“LENZ”), pursuant to which, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will merge with and into LENZ (the “Merger”), with LENZ continuing as a wholly owned subsidiary of Graphite and the surviving corporation of the Merger.

On December 6, 2023, Graphite filed with the Securities and Exchange Commission (“SEC”) a registration statement on Form S-4 (the “Form S-4”), as amended on January 18, 2024, February 5, 2024, and February 9, 2024, which contained a preliminary proxy statement/prospectus. The Form S-4 became effective on February 13, 2024, and a final proxy statement/prospectus (the “Proxy Statement/Prospectus”) was filed with the SEC on that day. The Proxy Statement/Prospectus solicits stockholder approval for, among other things, the Merger.

Certain Litigation

In connection with the Merger, one complaint has been filed in the United States District Court for the Northern District of California captioned Glen Chew v. Graphite Bio, Inc. et al., Case No. 3:24-cv-00613 (filed February 1, 2024) and one complaint has been filed in the United States District Court for the District of Delaware captioned Kevin Turner v. Graphite Bio, Inc. et al., Case No. 1:24-cv-00241-UNA (filed February 22, 2024) (collectively, the “Complaints”). The Complaints generally allege that the Proxy Statement/Prospectus filed by Graphite with the SEC misrepresents and/or omits certain purportedly material information relating to LENZ’s financial projections, the analyses performed by the financial advisor to Graphite’s Board of Directors in connection with the Merger, potential conflicts of interest of the financial advisor to Graphite’s Board of Directors, potential conflicts of interest of Graphite’s officers, and Graphite’s liquidation analysis. The Complaints assert violations of Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated thereunder against all defendants (Graphite, its Board of Directors and certain officers) and violations of Section 20(a) of the Exchange Act against Graphite’s directors and officers. The Complaints seek orders enjoining the proposed Merger, or in the event that the proposed Merger is consummated, an order rescinding the Merger or awarding rescissory damages, as well as costs, including attorneys’ and experts’ fees.

Graphite has also received twelve additional demand letters by purported Graphite stockholders from December 14, 2023 to February 28, 2024 seeking additional disclosures in the Proxy Statement/Prospectus (the “Demands”).

Graphite cannot predict the outcome of any litigation or the Demands. Graphite and the individual defendants intend to vigorously defend against the Complaints, the Demands, and any subsequently filed similar actions. It is possible additional lawsuits may be filed or additional demand letters may be received arising out of the Merger between February 28, 2024 and consummation of the Merger. Absent new or significantly different allegations, Graphite will not necessarily disclose such additional filings or demand letters.

Graphite believes that the disclosures set forth in the Proxy Statement/Prospectus comply fully with all applicable laws, and denies the allegations in the Complaints described above. Nevertheless, in order to moot plaintiffs’ disclosure claims, avoid nuisance and possible expense and business delays, and provide additional information to its stockholders, Graphite has determined voluntarily to supplement certain disclosures in the Proxy Statement/Prospectus with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal merit of the Complaints or the Demands described above, or of the necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Graphite specifically denies all allegations in the Complaints and the Demands that any additional disclosure was or is required or is material.

SUPPLEMENTAL DISCLOSURES

The following supplemental disclosures should be read in conjunction with the Proxy Statement/Prospectus, which should be read in its entirety. The inclusion in this supplement to the Proxy Statement/Prospectus of certain information should not be regarded as an indication that any of Graphite or its affiliates, directors, officers, or other representatives, or any other recipient of this information, considered, or now considers, it to be material, and such information should not be relied upon as such. Defined terms used but not defined herein have the meanings set forth in the Proxy Statement/Prospectus. For clarity, new text within restated paragraphs from the Proxy Statement/Prospectus is highlighted with bold, underlined text, and deleted text within restated paragraphs from the Proxy Statement/Prospectus is highlighted with strikethrough text.

The disclosure under the heading “The Merger – Background of the Transaction” is hereby amended and supplemented by replacing the third full paragraph on page 135 of the Proxy Statement/Prospectus in its entirety with the following:

At the Graphite board of directors meeting held on January 27, 2023, the Graphite board of directors established a Strategic Transaction Committee of the Graphite board of directors (the “Transaction Committee”), for convenience (and not because of any actual or perceived conflicts of interests), in order to assist the Graphite board of directors, as needed, in exploring strategic alternatives, including without limitation, a sale or other divestiture, including a spin-out of all, substantially all or a material portion of Graphite’s business or assets, a “reverse merger,” “merger of equals” or similar transaction, or a sale of control of Graphite. The members of the Transaction Committee did not receive any additional compensation related to their service on the Transaction Committee. The initial members of the Transaction Committee were the following independent directors, who were selected because they have significant experience with merger and acquisition transactions and/or clinical development: Abraham Bassan, Jerel Davis, Ph.D., Perry Karsen (Chair) and Smital Shah. The Graphite board of directors delegated authority to the Transaction Committee to, among other things: direct the process for the review and evaluation of any potential strategic transaction; provide guidance regarding a proposed strategic transaction to Graphite’s management and advisors; identify and engage appropriate advisors in connection with such strategic transaction; review, evaluate, pursue or reject any potential transaction or counterparty; and recommend to the full Graphite board of directors what action, if any, should be taken by the Graphite board of directors and Graphite with respect to a potential strategic transaction or other alternatives. Between January 30, 2023 and the signing of the Merger Agreement, the Transaction Committee generally met weekly and on an ad hoc basis as needed, with representatives of its advisors present. Throughout the Transaction Committee’s evaluation of a potential strategic transaction described below, the Transaction Committee conducted formal meetings, and its members were also in regular informal discussions with Graphite’s management and legal and financial advisors and with each other. The Transaction Committee also routinely met in executive session without Graphite’s management present.

The disclosure under the heading “The Merger – Certain Unaudited Financial Information – Graphite Liquidation Analysis” is hereby amended and supplemented by replacing the first full paragraph on page 169 of the Proxy Statement/Prospectus in its entirety with the following:

The Graphite liquidation analysis represents a range of estimates of Graphite’s aggregate net cash which could be available for distribution to Graphite stockholders in a scenario in which Graphite winds down its operations and liquidates. For purposes of this analysis, such range of estimates of Graphite’s aggregate cash was determined by Graphite management as follows: estimated net balance sheet liquidation value of Graphite (calculated as total assets minus total liabilities), plus estimated proceeds from assumed asset sales during the wind-down period, less estimated wind-down costs (taking into account a reserve for contingent liabilities), plus estimated interest income during the wind-down period, on a net after-tax basis. Key assumptions underlying the Graphite liquidation analysis included: (i) wind-down processes commencing in October 2023; (ii) an assumed initial predissolution liquidating distribution to Graphite stockholders in the amount of approximately $166.8 million in February 2024, after deducting costs and expenses, including approximately $750,000 in legal fees, the approximately $1.5 million in fees payable to Graphite’s strategic financial advisor, -$1.7 million in accounting fees, approximately $1.9 million in employee retention bonuses, and severance and benefits, approximately $5 million in insurance expenses and other transaction-related costs, with no adjustments for taxes; and (iii) the assumed completion of the liquidation and dissolution process and a liquidating distribution of all remaining net cash to Graphite stockholders in March 2027. The analysis resulted in an estimated cash distribution per share in February 2024 of $2.86 per share (assuming

approximately 58 million fully diluted shares outstanding), as well as an estimated range of after-tax liquidation values at March 2027 (i.e., the estimated aggregate available cash for distribution to holders of Graphite common stock as of such date) of $5.6 million in the low case and $11.1 million in the high case, and an estimated cash distribution per share in March 2027 of $0.10 per share in the low case or $0.19 in the high case.

The disclosure under the heading “The Merger – Opinion of Leerink Partners LLC – Discounted Cash Flow Analysis” is hereby amended and supplemented by replacing the third full paragraph on page 173 of the Proxy Statement/Prospectus in its entirety with the following:

Leerink Partners’ discounted cash flow analysis calculated the estimated present value of the stand-alone, unlevered, after-tax free cash flows that LENZ was forecasted to generate from January 31, 2024, through December 31, 2036, which unlevered, after-tax free cash flows were derived from the Graphite management risk-adjusted LENZ projections. Leerink Partners estimated the net present value of unlevered, after-tax free cash flows after fiscal year 2036 by assuming an annual decline of 50% of such cash flows in perpetuity (as provided to Leerink Partners by Graphite management). These cash flows were discounted to present value as of January 31, 2024, using a discount rate ranging from 11% to 13%, derived from a weighted average cost of capital calculation for LENZ, which Leerink Partners performed utilizing the capital asset pricing model with inputs that Leerink Partners determined were relevant based on publicly available data and Leerink Partners’ professional judgment, including target capital structure, levered and unlevered betas for certain companies deemed by Leerink Partners to be comparable to LENZ, and the equity market risk premium and yields for U.S. treasury bonds, and adjusted for LENZ’s estimated net cash balance of $57.3 million as of January 31, 2024, as provided by management of LENZ, in order to derive an implied equity value range for LENZ. This analysis resulted in an implied equity value for LENZ of approximately $460 million to $540 million and a corresponding implied exchange ratio of approximately 2.8075 to 3.2957, i.e., an implied equity value for LENZ that is substantially greater than the implied equity value for LENZ applying the estimated exchange ratio of 1.4135 shares of Graphite common stock utilized by Leerink Partners for purposes of its financial analyses.

The disclosure under the heading “The Merger – Opinion of Leerink Partners LLC – General” is hereby amended and supplemented by replacing the first full paragraph on page 174 of the Proxy Statement/Prospectus in its entirety with the following:

Leerink Partners is a full-service securities firm engaged in securities trading and brokerage activities as well as investment banking and financial advisory services. Leerink Partners has provided certain investment banking services to Graphite from time to time, for which it has received compensation but no such compensation was received in the past two years. Leerink Partners has not provided any investment banking services to nor received any compensation from LENZ in the past two years. In the ordinary course of business, Leerink Partners may in the future provide investment banking services to Graphite, LENZ or their respective affiliates and would expect to receive customary fees for the rendering of such services. In the ordinary course of its trading and brokerage activities, Leerink Partners has in the past and may in the future hold positions, for its own account or the accounts of its customers, in equity, debt or other securities of Graphite, LENZ or their respective affiliates.

The disclosure under the heading “Management Following The Merger – Non-Employee Director Compensation” is hereby amended and supplemented by replacing the third full paragraph on page 386 of the Proxy Statement/Prospectus in its entirety with the following:

The combined company’s board of directors intends to adopt an outside director compensation policy that is designed to provide a total compensation package that enables the combined company to attract and retain, on a long-term basis, high-caliber directors who are not employees or officers of the combined company or its subsidiaries. The outside director compensation policy is anticipated to become effective upon consummation of the merger. As a non-employee director of the combined company, after the effective time, Kimberlee C. Drapkin will receive compensation consistent with the terms outlined in LENZ’s Outside Director Compensation Policy attached as Exhibit 10.42 to the Form S-4. As of February 29, 2024, no Graphite executive officers are expected to serve as executive officers of the combined company following the consummation of the merger.

Forward-looking statements are subject to a number of risks and uncertainties, many of which involve factors or circumstances that are beyond Graphite’s control.
