Item 7.01			Regulation FD Disclosure

On September 27, 2022, Biohaven Pharmaceutical Holding Company Ltd. (“Biohaven” or “Company”) announced that the closing date of the previously announced acquisition of Biohaven by Pfizer Inc. (the “Merger”) is expected to be on October 3, 2022. The distribution for Biohaven’s previously announced spin-off of its Biohaven Ltd. subsidiary, which will own the Kv7 ion channel activators, glutamate modulation, myeloperoxidase inhibition and myostatin inhibition platforms, preclinical product candidates, and certain corporate infrastructure currently owned by Biohaven (the “Spin-Off”), is expected to occur immediately prior to the closing of Pfizer’s acquisition of Biohaven, also on October 3, 2022. The completion of the Merger and the Spin-Off remain subject to the closing conditions described in Biohaven’s Proxy Statement filed on August 30, 2022, including receipt of shareholder approval at Biohaven’s special meeting of shareholders to be held on September 29, 2022.

The information set forth in this Item 7.01 of this Current Report on Form 8-K is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

Special Note on Forward-Looking Statements

This communication contains forward-looking information about Pfizer Inc.’s proposed acquisition of the Company, the Company’s related spin-off of its development stage pipeline compounds, the Company’s commercial and pipeline portfolio, including rimegepant, expected best-in-class and growth potential, that involve substantial risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. Risks and uncertainties include, among other things, risks related to the satisfaction or waiver of the conditions to closing the proposed acquisition (including the failure to obtain necessary regulatory approvals and failure to obtain the requisite vote by the Company shareholders) in the anticipated timeframe or at all, including the possibility that the proposed acquisition does not close; the possibility that competing offers may be made; risks related to the ability to realize the anticipated benefits of the proposed acquisition, including the possibility that the expected benefits from the acquisition will not be realized or will not be realized within the expected time period; the risk that the businesses will not be integrated successfully; disruption from the transaction making it more difficult to maintain business and operational relationships; risks related to diverting management’s attention from the Company’s ongoing business operation; negative effects of this announcement or the consummation of the proposed acquisition on the market price of the Company’s common shares and/or operating results; significant transaction costs; unknown liabilities; the risk of litigation and/or regulatory actions related to the proposed acquisition, spin-off or the Company’s business; risks and costs related to the implementation of the separation of Biohaven Ltd., including timing anticipated to complete the separation and any changes to the configuration of the businesses included in the separation if implemented; the risk that the integration of the Company and Pfizer Inc. will be more difficult, time consuming or costly than expected; other business effects and uncertainties, including the effects of industry, market, business, economic, political or regulatory conditions; future exchange and interest rates; changes in tax and other laws, regulations, rates and policies; future business combinations or disposals; the uncertainties inherent in research and development, including the ability to meet anticipated clinical endpoints, commencement and/or completion dates for clinical trials, regulatory submission dates, regulatory approval dates and/or launch dates, as well as the possibility of unfavorable new clinical data and further analyses of existing clinical data; risks associated with interim data; the risk that clinical trial data are subject to differing interpretations and assessments by regulatory authorities; whether regulatory authorities will be satisfied with the design of and results from the clinical studies; whether and when drug applications may be filed in particular jurisdictions for rimegepant or zavegepant or any other investigational products; whether and when any such applications may be approved by regulatory authorities, which will depend on myriad factors, including making a determination as to whether the product’s benefits outweigh its known risks and determination of the product’s efficacy and, if approved, whether rimegepant, zavegepant or any such other products will be commercially successful; decisions by regulatory authorities impacting labeling, manufacturing processes, safety and/or other matters that could affect the availability or commercial potential of rimegepant, zavegepant or any such other products; uncertainties regarding the impact of COVID-19; and competitive developments.

You should carefully consider the foregoing factors and the other risks and uncertainties that affect the business of the Company described in the “Risk Factors” and “Forward-Looking Information and Factors That May Affect Future Results” sections of its Annual Report on Form 10-K, Quarterly Report on Form 10-Q and other documents filed from time to time with the U.S. Securities and Exchange Commission (the “SEC”), all of which are available at www.sec.gov. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and the Company assumes no obligation to, and does not intend to, update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise, unless required by law. The Company does not give any assurance that it will achieve its expectations.
