As previously disclosed, on August 7, 2022, Global Blood Therapeutics, Inc., a Delaware corporation (“GBT”, the “Company”, “we”, “our” or “us”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Pfizer Inc., a Delaware corporation (“Parent”), and Ribeye Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the Merger Agreement, and upon the terms and subject to the conditions described therein, Merger Sub will merge with and into the Company, with the Company surviving the merger as a wholly owned subsidiary of Parent (the “Merger”).  On August 19, 2022, GBT filed a preliminary proxy statement (the “Preliminary Proxy Statement”) with the Securities and Exchange Commission (“SEC”), and on August 29, 2022, GBT filed a definitive proxy statement (the “Proxy Statement”) with the SEC, in each case in connection with the Merger.

Since the filing of the Preliminary Proxy Statement, seven complaints have been filed in federal courts in New York, California and Delaware and a state court in California by purported GBT stockholders against GBT and members of the GBT board of directors in connection with the Merger:  Wang v. Global Blood Therapeutics, Inc., et al., Case No. 1:22-cv-07157 (filed August 22, 2022) (S.D.N.Y.); Pepe v. Global Blood Therapeutics, Inc., et al., Case No. 3:22-cv-04895 (filed August 26, 2022) (N.D. Cal.); Lawrence v. Global Blood Therapeutics, Inc., et al., Case No. 1:22-cv-07641 (filed September 8, 2022) (S.D.N.Y.); Kent v. Global Blood Therapeutics, Inc., et al., Case No. 1:22-cv-01184-UNA (filed September 8, 2022) (D. Del.); Minzer v. Global Blood Therapeutics, Inc., et al., Case No. 3:22-cv-05136 (filed September 9, 2022) (N.D. Cal.); and Riley v. Global Blood Therapeutics, Inc., et al., Case No. 1:22-cv-07740 (filed September 11, 2022) (S.D.N.Y.) (collectively, the “Federal Stockholder Litigation”) and Berger v. Global Blood Therapeutics, Inc., et al., Case No. 22-CIV-03675 (filed September 8, 2022) (Cal. Sup. Ct., San Mateo Cnty.) (the “State Stockholder Litigation” and, collectively with the Federal Stockholder Litigation, the “Stockholder Litigation”).  Each of the complaints in the Federal Stockholder Litigation alleges that, among other things, the Preliminary Proxy Statement and/or the Proxy Statement omitted certain material information in violation of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated thereunder.  The State Stockholder Litigation purports to allege securities fraud under California Corporations Code Section 25401 and misrepresentation claims under California common law relating to the Proxy Statement.  Additionally, on August 28, 2022, September 1, 2022, September 2, 2022, September 2, 2022 and September 12, 2022, five purported GBT stockholders sent demand letters alleging similar insufficiencies in the disclosures in the Preliminary Proxy Statement and/or the Proxy Statement in violation of Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder (such letters, the “Demand Letters” and, collectively with the Stockholder Litigation, the “Litigation Matters”).  The plaintiffs in the Stockholder Litigation seek various remedies, including an order enjoining the defendants from proceeding with the Merger, requiring the defendants to disclose allegedly material information that was allegedly omitted from the Proxy Statement, rescinding the Merger in the event that it is consummated or granting rescissory damages, declaring that the defendants violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, awarding costs, including attorneys’ and expert fees and expenses, and granting such other and further relief as the court may deem just and proper.

GBT believes that the claims asserted in the Litigation Matters are without merit and no additional disclosures are required under applicable laws. However, in order to avoid the risk of the Litigation Matters delaying or adversely affecting the Merger and to minimize the costs, risks and uncertainties inherent in litigation, and without admitting any liability or wrongdoing, GBT has determined to voluntarily make the following supplemental disclosures to the Proxy Statement, as described in this Current Report on Form 8-K.  Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, GBT specifically denies all allegations in the Litigation Matters that any additional disclosure was or is required.

These supplemental disclosures will not change the consideration to be paid to GBT stockholders in connection with the Merger or the timing of the special meeting of GBT stockholders (the “Special Meeting”) to be held virtually via live webcast on September 30, 2022, beginning at 8:00 a.m. Pacific Time.  The Special Meeting can be accessed by visiting www.virtualshareholdermeeting.com/GBT2022SM. The GBT board of directors continues to unanimously recommend that you vote “FOR” the proposals to be voted on at the Special Meeting described in the Proxy Statement.

The last sentence of the sixth full paragraph on page 43 is amended and supplemented as follows (with new text underlined):

The analysis indicated a range of implied per share equity value for the GBT common stock (rounded to the nearest $0.25) of approximately $44.25 to $83.75, which J.P. Morgan compared to the implied per share equity value of the Merger Consideration to be paid to GBT stockholders of $68.50.

The last paragraph on page 43 and carry over paragraph on page 44 is amended and supplemented as follows (with new text underlined):

Discounted Cash Flow Analysis. J.P. Morgan conducted a discounted cash flow analysis for the purpose of determining the fully diluted equity value per share for the GBT common stock. J.P. Morgan calculated the unlevered free cash flows that the Company is expected to generate from October 1, 2022 through December 31, 2042, including the impact of certain net operating losses based upon the Management Forecasts. J.P. Morgan also calculated a range of terminal values of the Company at the end of this period by applying perpetual growth rates ranging from (50.0%) to (30.0%) for Oxbryta, GBT601 and inclacumab, 5.0% for research assets and 2.0% for corporate overhead and other unallocated expenses based on guidance provided by the Company’s management and J.P. Morgan’s professional judgment and experience, to estimates of the unlevered free cash flow of the Company during calendar year 2042 as set forth in the Management Forecasts. The unlevered free cash flows and the range of terminal values were then discounted to present values as of September 30, 2022 using a range of discount rates from 10.5% to 13.5%, which were chosen by J.P. Morgan based upon an analysis of the weighted average cost of capital of the Company, taking into account macro-economic assumptions, estimates of risk, the Company’s capital structure and other factors that J.P. Morgan deemed appropriate. The present value of the unlevered free cash flow estimates and the range of terminal values were then adjusted by adding net cash as of September 30, 2022, $351 million, which estimate was provided by the management of the Company. This analysis indicated a range of implied equity values for the Company, which J.P. Morgan divided by the number of outstanding shares of GBT common stock, calculated on a fully-diluted basis and adjusted for the Company’s assumed future equity raise of $200 million in gross proceeds in 2023, to derive a range of implied per share equity value for the GBT common stock (rounded to the nearest $0.25) of approximately $52.25 and $65.50, which J.P. Morgan compared to the implied per share equity value of the Merger Consideration to be paid to GBT stockholders of $68.50.

The first full paragraph on page 44 is amended and supplemented as follows (with new text underlined):

Certain Other Information. J.P. Morgan also reviewed certain publicly available equity research analyst price targets, focusing on the Company’s 52 week historical trading and analyst price targets, in each case as of August 3, 2022 (the last trading day prior to the date on which the trading price of GBT common stock was perceived by J.P. Morgan to be affected by a potential transaction) which ranged from $22.30 to $40.26 and $31.00 to $102.00, respectively. J.P. Morgan noted that historical stock trading and analyst price targets analyses are not valuation methodologies but were presented merely for informational purposes.



The disclosure in the section entitled “Proposal 1: Adoption of the Merger Agreement—Opinion of Centerview”, beginning on page 45 of the Proxy Statement, is hereby amended as follows:

The fourth full paragraph on page 48 is amended and supplemented as follows (with new text underlined and deleted text marked with a strikethrough):

The last paragraph on page 48 and carry over paragraph on page 49 is amended and supplemented as follows (with new text underlined):

Based on this analysis and other considerations that Centerview deemed relevant in its professional judgment and experience, Centerview selected a reference range of EV/2026E Revenue Trading Multiples of 2.00x to 4.25x to apply to the Company’s estimated calendar year risk-adjusted 2026 net revenue of $1.293 billion as set forth in the Management Forecasts and to Wall Street research analyst consensus estimated net revenue for the Company for calendar year 2026 of $912 million. In selecting these ranges of EV/2026E Revenue Trading Multiples, Centerview made qualitative judgments based on its experience and professional judgment concerning differences between the business, operational and/or financial characteristics of the Company and the selected companies that could affect their public trading values in order to provide a context in which to consider the results of the quantitative analysis. Applying this range of EV/2026E Revenue Trading Multiples to the Company’s estimated calendar year risk-adjusted 2026 net revenue as set forth in the Management Forecasts of $1.293 billion under the Management Forecasts, and to Wall Street research analyst consensus estimated net revenue for the Company for calendar year 2026 of $912 million, and adding to such amounts the Company’s estimated net cash as of September 30, 2022 of $351 million (adjusted for the conversion of the Convertible Notes, if applicable), provided by the Company management as set forth in the Internal Data, and dividing the results of the foregoing calculations by the number of fully diluted outstanding shares of GBT common stock (determined using the treasury stock method and taking into account outstanding in-the-money options, restricted stock units, performance stock units and shares issuable upon conversion of the Convertible Notes (as defined in the section of this proxy statement entitled “Proposal 1: Adoption of the Merger Agreement—Capped Call Transactions”), if applicable), based on information provided by the Company management as of August 4, 2022 as set forth in the Internal Data. For the purposes of Centerview’s analysis, net cash and fully diluted outstanding shares of GBT common stock varied depending on whether the Convertible Notes were deemed to be in-the-money (at implied equity values per share above $31.75) or out-of-the-money (at implied equity values per share at or below $31.75). This analysis resulted in an implied per share equity value range for shares of GBT common stock of approximately $35.85 to $71.65 and $25.45 to $52.90, respectively, rounded to the nearest $0.05. Centerview then compared these ranges to the Merger Consideration of $68.50 per share to be paid to the holders of shares of GBT common stock (other than Excluded Shares) pursuant to the Merger Agreement.

The last paragraph on page 49 and carry over paragraph on page 50 is amended and supplemented as follows (with new text underlined):

Based on this analysis and other considerations that Centerview deemed relevant in its experience and professional judgment, related to, among other things, differences in the business, operational and/or financial conditions and prospects of the Company and the companies included in the selected precedent transactions analysis, Centerview selected a reference range of Four-Year Forward Revenue Multiples of 3.00x to 4.50x derived from the selected precedent transactions. Centerview applied this reference range of Four-Year Forward Revenue Multiples to Wall Street research analyst consensus estimated four-year forward net revenue of $874 million, and added to it the Company’s estimated net cash as of September 30, 2022 of $351 million (adjusted for conversion of the Convertible Notes, if applicable), adjusted for an estimated $77 million in change of control payments and prepayment penalties under the Company’s outstanding term loan payable in connection with the Transaction, provided by the Company management as set forth in the Internal Data, and divided the result of the foregoing calculations by the Company’s fully diluted outstanding shares of GBT common stock (determined using the treasury stock method and taking into account outstanding in-the-money options, restricted stock units, performance stock units and shares issuable upon conversion of the Convertible Notes, including additional shares of GBT common stock issued as a result of the make-whole with respect to the Convertible Notes, if applicable) based on information provided by the Company management as of August 4, 2022 as set forth in the Internal Data. For the purposes of Centerview’s analysis, net cash and fully diluted shares varied depending on whether the Convertible Notes were deemed to be in-the-money (at implied equity values per share above $31.75) or out-of-the-money (at implied equity values per share at or below $31.75). This analysis resulted in an implied per share equity value range for shares of GBT common stock of approximately $34.55 to $50.35, rounded to the nearest $0.05. Centerview then compared this range to the Merger Consideration of $68.50 per share to be paid to the holders of shares of GBT common stock (other than Excluded Shares) pursuant to the Merger Agreement.

The second full paragraph on page 50 is amended and supplemented as follows (with new text underlined):

In performing this analysis, Centerview calculated a range of equity values for shares of GBT common stock by (a) discounting to present value as of September 30, 2022 using discount rates ranging from 10.5% to 12.5% (reflecting Centerview’s analysis of the Company’s weighted average cost of capital based on considerations that Centerview deemed relevant in its professional judgment and experience, taking into account certain metrics, including yields for U.S. treasury notes, levered and unlevered betas for comparable group companies, market risk and size premia) and using a mid-year convention: (i) the forecasted risk-adjusted, after-tax unlevered free cash flows of the Company over the period beginning on October 1, 2022 and ending on December 31, 2042, utilized by Centerview based on the Management Forecasts, (ii) an implied terminal value of the Company, calculated by Centerview by applying a perpetuity growth rate of (40%) assuming that unlevered free cash flows would decline in perpetuity after December 31, 2042 (with the exception of cash flows associated with research assets (perpetuity growth rate of 5%) and corporate overhead and other unallocated expenses (perpetuity growth rate of 2%)), based on guidance provided by the Company management, and (iii) tax savings from usage of the Company’s federal net operating losses of $1.081 billion as of September 30, 2022 and the Company’s future losses and (b) adding to the foregoing results the Company’s estimated net cash as of September 30, 2022, $351 million (adjusted for the conversion of the Convertible Notes, if applicable), which amount was provided by the Company management as set forth in the Internal Data, and an assumed equity raise of $200 million in 2023 as set forth in the Internal Data. Centerview divided the result of the foregoing calculations by the Company’s fully diluted outstanding shares of GBT common stock (determined using the treasury stock method and taking into account outstanding in-the-money options, restricted stock units, performance stock units and shares issuable upon conversion of the Convertible Notes, if applicable), based on information provided by the Company management as of August 4, 2022 as set forth in the Internal Data. This analysis resulted in a range of implied equity values per share of GBT common stock of $56.35 to $65.25, rounded to the nearest $0.05. Centerview then compared this range to the Merger Consideration of $68.50 per share to be paid to the holders of shares of GBT common stock (other than Excluded Shares) pursuant to the Merger Agreement.
