5.1						Opinion of Maples & Calder.
23.1						Consent of Maples & Calder (included in Exhibit 5.1).
104						The cover page of this Current Report on Form 8-K formatted as Inline XBRL.

As of September 23, 2022, the Company is aware of eight complaints related to the Transactions having been filed and has received three letters making similar allegations (collectively, the “Actions”).

On July 8, 2022, the first of eight lawsuits was filed in the United States District Court for the Southern District of New York by a purported stockholder of the Company against the Company and the members of the Company’s Board of Directors alleging that the proxy statement on Schedule 14A filed by the Company in connection with the Transactions (the “Proxy Statement”) contained alleged material misstatements and/or omissions in violation of federal law. The lawsuits are captioned O’Dell v. Biohaven Pharmaceutical Holding Company Ltd., et al., Case 1:22-cv-05834, Ranson v. Biohaven Pharmaceutical Holding Company Ltd., et al., Case 1:22-cv-05938, Whitfield v. Biohaven Pharmaceutical Holding Company Ltd., et al., Case 1:22-cv-05940, Hopkins v. Biohaven Pharmaceutical Holding Company Ltd., et al., Case 1:22-cv-05988, Bushansky v. Biohaven Pharmaceutical Holding Company Ltd., et al., Case 1:22-cv-05979, Adamson v. Biohaven Pharmaceutical Holding Company Ltd., et al., Case 1:22-cv-06299, Jones v. Biohaven Pharmaceutical Holding Company Ltd., et al., Case 1:22-cv-07864, and Scott v. Biohaven Pharmaceutical Holding Company Ltd., et al., Case 1:22-cv-07868. Each of these actions seeks injunctive and other equitable relief, including the disclosure of additional information in advance of the stockholder vote on the Transactions, as well as money damages and an award of plaintiffs’ costs and expenses.

On each of July 15, 2022, September 15, 2022, and September 16, 2022, the Company received a letter from another purported stockholder of the Company making similar allegations and threatening to seek similar relief.

Additional lawsuits arising out of the Transactions may be filed in the future.

Supplemental Proxy Statement Disclosure

The Company believes that the claims asserted in the Actions are without merit and supplemental disclosures are not required or necessary under applicable laws. Nonetheless, to avoid the risk that the Actions may delay or otherwise adversely affect the consummation of the Transactions and in order to minimize the expense of defending such Actions, without admitting any liability or wrongdoing, the Company is electing to make the following supplemental disclosures to the Proxy Statement. The Company denies the allegations of the Actions, and denies any violation of law. The Company believes that the Proxy Statement disclosed all material information required to be disclosed therein, and denies that the supplemental disclosures are material or are otherwise required to be disclosed. Nothing in the supplemental disclosures or this Current Report on Form 8-K should be deemed an admission of the legal necessity or materiality of any supplemental disclosures under applicable laws.

SUPPLEMENT TO PROXY STATEMENT

This supplemental information should be read in conjunction with the Proxy Statement, which should be read in its entirety. Page references in the below disclosures are to the pages in the Proxy Statement, and defined terms used but not defined herein have the meanings set forth in the Proxy Statement. Without admitting in any way that the disclosures below are material or otherwise required by law, the Company makes the following amended and supplemental disclosures. For clarity, within amended and restated paragraphs from the Proxy Statement, new text is highlighted with bold, underlined text and deleted text is highlighted with crossed-out text.

The disclosure in the section of the proxy statement entitled “THE TRANSACTIONS (PROPOSAL NO. 1)—Opinion of Centerview Partners LLC—Summary of Centerview Financial Analysis—Selected Public Company Analysis” is hereby amended and supplemented by replacing the fourth paragraph on page 53 of the proxy statement in its entirety with the following:

Based on this analysis and other considerations that Centerview deemed relevant in its professional judgment and experience, Centerview selected a reference range of 2025E EV/Revenue Multiples of 3.0x to 4.5x. In selecting this range of 2025E EV/Revenue 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 2025E EV/Revenue Multiples to the Company’s estimated calendar year risk-adjusted 2025 revenue (excluding $75 million of non-recurring milestones expected to be earned in 2025, per the forecasts) of $2.313 billion, as set forth in the internal data, and subtracting from it the Company’s estimated net debt (calculated as debt and preferred stock less cash, cash equivalents and marketable securities and referred to as “estimated net debt” throughout this section) of $581 million as of March 31, 2022 (which was adjusted for a $35 million payment associated with the previously announced acquisition of Channel Biosciences and included certain change of control payments under the Company’s outstanding term loan and preferred equity payable in connection with the Transaction), and dividing the result of the foregoing calculations by the number of fully diluted outstanding Company Shares (calculated based on approximately 71.0 million Company Shares and, determined using the treasury stock method, and taking into account the dilutive impact of approximately 8.4 million outstanding in-the-money options, restricted stock units, Company Stock Options with a weighted average exercise price of $53.98, approximately 2.0 million unvested Company Restricted Stock Units, approximately 40,000 performance stock units and approximately 100,000 warrants with a weighted average exercise price of $56.46) as of May 6, 2022 based on the internal data, resulted in an implied per share equity value range of approximately $83.00 to $126.00, rounded to the nearest $1.00. Centerview then compared the results of the above analysis to the $156.70 per share value of the Transaction Consideration to be paid to the holders of Company Shares (other than Excluded Shares and any Company Shares held by any affiliate of the Company or by Pfizer) pursuant to the Merger Agreement and the Distribution Agreement.

The disclosure in the section of the proxy statement entitled “THE TRANSACTIONS (PROPOSAL NO. 1)—Opinion of Centerview Partners LLC—Summary of Centerview Financial Analysis—Selected Precedent Transactions Analysis” is hereby amended and supplemented by replacing the first full paragraph on page 55 of the proxy statement in its entirety with the following:

Based on this analysis and other considerations that Centerview deemed relevant in its professional judgment and experience, Centerview selected a reference range of 6.0x to 8.0x implied three-year forward revenue multiples derived from the selected precedent transactions. In selecting this range of three-year forward revenue 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 target companies included in the selected transactions and other factors that could affect each transaction or other values in order to provide a context in which to consider the results of the quantitative analysis. Applying this range of three-year forward revenue multiples to the Company’s estimated three-year forward risk-adjusted revenue (excluding $53 million of non-recurring milestones per the forecasts) of $1.814 billion, as set forth in the internal data, and subtracting from it the Company’s estimated net debt of $581 million as of March 31, 2022 (which was adjusted for a $35 million payment associated with the previously announced acquisition of Channel Biosciences and included certain change of control payments under the Company’s outstanding term loan and preferred equity payable in connection with the transaction), and dividing the result of the foregoing calculations by the number of fully diluted outstanding Company Shares (calculated based on approximately 71.0 million Company Shares and, determined using the treasury stock method, and taking into account the dilutive impact of approximately 8.4 million outstanding in-the-money options, restricted stock units, Company Stock Options with a weighted average exercise price of $53.98, approximately 2.0 million unvested Company Restricted Stock Units, approximately 40,000 performance stock units and approximately 100,000 warrants with a weighted average exercise price of $56.46) as of May 6, 2022 based on the internal data, resulted in an implied per share equity value range of approximately $132.00 to $176.00, rounded to the nearest $1.00. Centerview then compared the results of the above analysis to the $156.70 per Company Share value of the Transaction Consideration to be paid to the holders of Company Shares (other than Excluded Shares and any Company Shares held by any affiliate of the Company or by Pfizer) pursuant to the Merger Agreement and the Distribution Agreement.

The disclosure in the section of the proxy statement entitled “THE TRANSACTIONS (PROPOSAL NO. 1)—Opinion of Centerview Partners LLC—Summary of Centerview Financial Analysis—Discounted Cash Flow Analysis” is hereby amended and supplemented by replacing the third paragraph on page 55 of the proxy statement in its entirety with the following:

In performing this analysis, Centerview calculated a range of per Company share equity values by (a) discounting to present value as of March 31, 2022 using discount rates ranging from 9.0% to 12.0% (reflecting Centerview’s analysis of the Company’s weighted average cost of capital, based on considerations deemed relevant in its professional judgment and experience, taking into account certain metrics including levered and unlevered betas for a comparable group of companies) 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 March 31, 2022 and ending on December 31, 2043, utilized by Centerview based on the forecasts as described in the section of this proxy statement entitled “The Merger-Unaudited Prospective Financial Information of the Company” beginning on page 57, (ii) an implied terminal value of the Company, calculated by Centerview by assuming that unlevered free cash flows would decline in perpetuity after December 31, 2043 at a rate of free cash flow decline of 50% year over year (which perpetuity decline rate was based on considerations that Centerview deemed relevant in its professional judgment and experience), and (iii) tax savings from usage of the Company’s deferred tax assets of $10.5 billion, estimated foreign net operating losses of $747 million as of December 31, 2021, accrued losses of $220 million as of December 31, 2021, federal R&D credits and orphan drug credits of $20 million as of December 31, 2021 and future losses and (b) subtracting from the foregoing results the Company’s estimated net debt of $581 million as of March 31, 2022 (which was adjusted for a $35 million payment associated with the previously announced acquisition of Channel Biosciences and included certain change of control payments under the Company’s outstanding term loan and preferred equity payable in connection with the Transaction). Centerview divided the result of the foregoing calculations by the number of fully diluted outstanding Company Shares (calculated based on approximately 71.0 million Company Shares and, determined using the treasury stock method, and taking into account the dilutive impact of approximately 8.4 million outstanding in-the-money options, restricted stock units, Company Stock Options with a weighted average exercise price of $53.98, approximately 2.0 million unvested Company Restricted Stock Units, approximately 40,000 performance stock units and approximately 100,000 warrants with a weighted average exercise price of $56.46) as of May 6, 2022 based on the internal data, resulting in a range of implied equity values per Share of $139.00 to $177.00 rounded to the nearest $1.00. Centerview then compared the results of the above analysis to the $156.70 per Company Share value of the Transaction Consideration to be paid to the holders of Company Shares (other than Excluded Shares and any Company Shares held by any affiliate of the Company or by Pfizer) pursuant to the Merger Agreement and the Distribution Agreement.

The disclosure in the section of the proxy statement entitled “THE TRANSACTIONS (PROPOSAL NO. 1)—Opinion of Centerview Partners LLC—Other Factors—Analyst Price Target Analysis” is hereby amended and supplemented by replacing the second bullet on page 56 of the proxy statement in its entirety with the following:

•Analyst Price Target Analysis. Centerview reviewed available stock price targets for the Company Shares in eleven recently published, publicly available Wall Street research analyst reports as of May 9, 2022 (the last trading day before the public announcement of the Transaction), which indicated low and high stock price targets for the Company ranging from $135.00 to $182.00 per share, with the median of such price targets being $162.50.

The disclosure in the section of the proxy statement entitled “THE TRANSACTIONS (PROPOSAL NO. 1)—Opinion of Centerview Partners LLC—Other Factors—Premiums Paid Analysis” is hereby amended and supplemented by replacing the third bullet on page 56 of the proxy statement in its entirety with the following:

•Premiums Paid Analysis. Centerview performed an analysis of premiums paid in the selected transactions, as set forth above in “-Opinion of the Company’s Financial Advisor-Selected Precedent Transactions Analysis.” The premiums in this analysis were calculated by comparing the per share acquisition price in each transaction to the closing price of the target company’s common stock for the date one day prior to the date on which the trading price of the target’s common stock was perceived to be affected by a potential transaction. Based on the analysis above and other considerations that Centerview deemed relevant in its professional judgment, Centerview applied a reference range of 45% to 65% to the Company’s closing stock price on May 9, 2022 (the last trading day before the public announcement of the Transaction) of

$83.14, which resulted in an implied price range of approximately $121.00 to $137.00 per share, rounded to the nearest $1.00.

The disclosure in the section of the proxy statement entitled “THE TRANSACTIONS (PROPOSAL NO. 1)—Opinion of Centerview Partners LLC—General” is hereby amended and supplemented by replacing the first full paragraph on page 57 of the proxy statement in its entirety with the following:

Centerview is a securities firm engaged directly and through affiliates and related persons in a number of investment banking, financial advisory and merchant banking activities. In the two years prior to the date of its written opinion, except for Centerview’s current engagement, Centerview had not been engaged to provide financial advisory or other services to the Company, and Centerview did not receive any compensation from the Company during such period. In the two years prior to the date of its written opinion, Centerview had been engaged to provide and is currently providing financial advisory services to Pfizer, including in connection with Pfizer’s acquisition of Arena Pharmaceuticals, Inc. in 2022 and certain other strategic matters unrelated to the Merger. Centerview has received, or expects to receive, between $20 million and $30 million in aggregate compensation from Pfizer for work performed during such period. Centerview may provide financial advisory and other services to or with respect to the Company or Pfizer or their respective affiliates in the future, for which Centerview may receive compensation. Certain (i) of Centerview and its affiliates’ directors, officers, members and employees, or family members of such persons, (ii) of Centerview’s affiliates or related investment funds and (iii) investment funds or other persons in which any of the foregoing may have financial interests or with which they may co-invest, may at any time acquire, hold, sell or trade, in debt, equity and other securities or financial instruments (including derivatives, bank loans or other obligations) of, or investments in, the Company, Pfizer, or any of their respective affiliates, or any other party that may be involved in the Transaction.

Special Note on Forward-Looking Statements

This communication contains forward-looking information about Pfizer’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 SpinCo, 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 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.
