**To Our Shareholders,**

2025 was a year of deliberate focus and execution at Biohaven. We advanced programs with strong scientific foundations, sharpened our strategic priorities, and reinforced financial discipline—while remaining deeply committed to our mission of delivering transformative therapies for patients. Our progress in 2025 and into the new year strengthens our confidence in Biohaven's strategy and our ability to create durable long-term shareholder value.

**Revolutionizing the Inflammation and Immunology Treatment Paradigm Through Extracellular Protein Degradation**

Our most significant advances in 2025 came from our MoDE and TRAP extracellular protein degrader platform, which remains the central pillar of our long-term strategy in inflammation and immunology. These technologies enable the selective, rapid removal of disease-causing circulating proteins while preserving healthy immune function—representing a fundamentally new approach to treating immune-mediated disease.

**Key achievements include:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **IgA Nephropathy (BHV-1400):** First dosing in IgAN patients resulted in early observations of both biomarker and clinical responses, including selective lowering of disease-causing Gd-IgA1, improvements in proteinuria, hematuria, fatigue, and kidney function. These results build on strong Phase 1 data demonstrating rapid and sustained reductions in Gd-IgA1 exceeding 80% after a single subcutaneous dose. A pivotal study is expected to initiate in early 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Graves' Disease (BHV-1300):** First-in-patient clinical experience demonstrated complete suppression of pathogenic TSH receptor–stimulating antibodies with normalization of thyroid hormone levels within weeks. Together with best-in-class IgG reductions observed in healthy volunteers, these data support our plan to initiate a pivotal study in 2026.

With this program, we are entering a new era of **precision immunology**, and Biohaven has the most advanced technologies in clinical testing to lead the way. There is no other immunologic-modulating platform that targets disease through extracellular protein degradation in the way that our MoDE and TRAP degraders do. We are the first in the clinic to harness the body's natural clearance mechanisms to selectively remove disease-causing proteins—effectively plucking out the pathogenic drivers of disease while leaving the rest of the immune system intact. For patients, this approach has the potential to fundamentally change their treatment outlook: faster results, fewer tradeoffs, and therapies that can be administered simply and safely at home. Just as we helped define a new treatment paradigm with Nurtec by targeting disease biology with precision and scalability, we believe extracellular protein degradation has the potential to create a similarly transformative opportunity across multiple large immune-mediated diseases.

Importantly, the **market opportunity for extracellular protein degradation is significant**. As we think about what Biohaven achieved with Nurtec—creating a new category, expanding access, and reaching millions of patients globally—we see a similar opportunity for our degrader platform to transform treatment standards across multiple indications over time. While still early, we believe this platform has the potential to be a **foundational, multi-billion-dollar franchise** that drives long-term growth and impact.

**Advancing a Differentiated Epilepsy Franchise**

Our **selective Kv7 ion channel activator, opakalim**, continues to demonstrate the potential to be a paradigm-shifting therapy for focal epilepsy.

Highlights include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In an ongoing open-label extension study, the **majority of participants treated for at least six months achieved ≥50% reductions in seizure frequency** compared to pretreatment baseline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Opakalim was **well tolerated**, with a low incidence of central nervous system adverse events, representing a highly differentiated safety profile relative to other antiseizure medicines.

We believe opakalim addresses a significant unmet need for effective seizure control without the burden of limiting side effects, and we expect to deliver **pivotal results in 2026**.

------

**Targeting High-Quality Weight Loss in Obesity**

Our third key program, **taldefgrobep alfa**, reflects our commitment to pursuing differentiated biology in large, underserved markets.

Key developments include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Initiation of a **Phase 2 proof-of-concept study in obesity** in the fourth quarter of 2025, with topline results expected in 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A unique mechanism designed to **reduce fat mass while increasing lean muscle and bone density**, supported by favorable Phase 1 body composition data and a strong safety record across more than 700 participants.

We believe taldefgrobep has the potential to redefine what constitutes meaningful and sustainable weight loss and to address important limitations of existing therapies.

**Demonstrating Platform Breadth in Oncology**

In oncology, recent clinical results further demonstrate the **breadth and versatility of Biohaven's science beyond our core immunology focus**. Our Trop2 ADC is demonstrating a highly differentiated profile in regard to safety and efficacy in initial clinical testing, and our FGFR3 targeting ADC is the first of its kind in clinical testing.

Key updates include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **BHV-1510 (Trop2 ADC):** Continued clinical activity observed in non-small cell lung, endometrial, and urothelial cancers, including confirmed responses in heavily pretreated patients, with a differentiated and manageable safety profile. Compelling preliminary efficacy has been shown at the 2.5mg/kg Q3W dosing in combination with anti-PD(L)1 with confirmed overall response rate of 73% (8/11). Notably, BHV-1510 is the **first and only Trop2 ADC in the clinic with the potential for subcutaneous administration**, reflecting a design philosophy consistent with our patient-centric approach.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **BHV-1530 (FGFR3 ADC):** Ongoing dose escalation continues without dose-limiting toxicities to date, supporting further development in FGFR3-driven malignancies and we are now exploring doses in the expected therapeutic range.

These encouraging results reinforce the **depth of Biohaven's discovery and translational capabilities**. Given the strength of the data and the capital requirements of oncology development, we will continue **evaluating strategic partnership opportunities and other creative pathways** to best advance these programs while maximizing value for shareholders.

**Sustaining Innovation Through Discovery**

Our discovery engine continues to generate the next wave of innovation, advancing multiple novel programs with the potential for future clinical development or strategic partnering, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **BHV-1955** for tinnitus targeting the oxytocin receptor,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **BHV-2120**, a brain-penetrant TRPM3 inhibitor for epilepsy,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **BHV-8555**, targeting alpha-synuclein aggregation in Parkinson's disease, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **BHV-8100**, a PKM2 activator for neurodegenerative disorders and aging.

These programs reflect our commitment to sustained innovation while maintaining a disciplined and intentional cadence of advancement.

**Financial Discipline and Strategic Focus**

In parallel with pipeline progress, we **redoubled our commitment to financial discipline**:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Implemented strategic portfolio and cost-optimization measures to prioritize investment in our three highest-value, late-stage programs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Aligned spending with clear development milestones while preserving flexibility for future opportunities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthened our balance sheet through disciplined capital raising and strategic financing initiatives.

This approach positions Biohaven to efficiently execute through upcoming milestones while maintaining optionality across our broader portfolio.

**Looking Ahead**

As we enter 2026, we believe Biohaven is well positioned to deliver multiple value-creating milestones, including:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Initiation of pivotal studies for our lead TRAP and MoDE degraders,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pivotal data readouts for opakalim in focal epilepsy, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Topline Phase 2 results for taldefgrobep in obesity.

Our strategy is clear, our science is strong, and our team is deeply motivated by the patients we serve. We are working toward a future in which disease is precisely targeted, treatments are simpler and safer, and meaningful impact can be delivered at scale. Days matter for patients waiting—and the year ahead promises to be one of continued progress.

Thank you for your continued trust and support.

Sincerely,

**Vlad Coric, M.D.**

Chairman and Chief Executive Officer

Biohaven Ltd.

**PROXY STATEMENT FOR THE 2026 ANNUAL MEETING OF SHAREHOLDERS**

**To Be Held on April 28, 2026**

**QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING**

***Why did I receive a Notice of Internet Availability of Proxy Materials instead of paper copies of the proxy materials?***

Pursuant to the SEC "Notice and Access" rules, we are furnishing our proxy materials to our shareholders over the Internet instead of mailing each of our shareholders paper copies of those materials. Accordingly, we are sending our shareholders by mail a Notice of Internet Availability of Proxy Materials, which we refer to as the Notice, containing instructions on how to access our proxy materials over the Internet and how to vote. The Notice is not a ballot or proxy card and cannot be used to vote your common shares. You will not receive paper copies of the proxy materials unless you request the materials by following the instructions in the Notice or on the website referred to in the Notice.

If you own common shares in more than one account—for example, in a joint account with your spouse and in your individual brokerage account—you may have received more than one Notice. To vote all of your common shares, please follow each of the separate proxy voting instructions that you received for your common shares held in each of your different accounts.

We are sending the Notice to our shareholders by mail beginning on or about March 13, 2026.

***What information does the Notice contain?***

The Notice includes, among other matters: (i) the place, date and time of the 2026 Annual Meeting of Shareholders (the "annual meeting"); (ii) a brief description of the proposals to be voted on at the annual meeting and the voting recommendation of the Board of Directors (the "Board" or the "Board of Directors") of Biohaven Ltd. ("Biohaven" or the "Company") with regard to each proposal; (iii) information regarding the website where the proxy materials are posted; (iv) various methods by which a shareholder may request paper or electronic copies of the proxy materials; and (v) instructions on how to vote by Internet, by telephone, by mail or in person at the annual meeting.

***Why am I receiving access to these materials?***

You are receiving access to these proxy materials because the Board is soliciting your proxy to vote at the annual meeting, including at any adjournments or postponements of the annual meeting. You are invited to attend the annual meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the annual meeting to vote your shares. Instead, you may simply follow the instructions below to submit your proxy by phone or online, or, if you received printed proxy materials, complete, date, sign and return the proxy card enclosed with your materials.

The approximate date on which these proxy materials are first being made available to all shareholders of record entitled to vote at the annual meeting is March 13, 2026.

***How do I attend the annual meeting?***

The annual meeting will be held on Tuesday, April 28, 2026 at 10:00 a.m. local time at the Rosewood Little Dix Bay, Lee Road, Virgin Gorda, British Virgin Islands VG 1150. Information on how to vote in person at the annual meeting is discussed below.

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

***Who can vote at the annual meeting?***

Only shareholders of record at the close of business on March 3, 2026 will be entitled to vote at the annual meeting. On this record date, there were 150,420,584 common shares outstanding, each of which is entitled to one vote per share. Each common share confers upon the holder the right to one vote at the annual meeting.

*Shareholder of Record: Shares Registered in Your Name*

If on March 3, 2026 your shares were registered directly in your name with Biohaven's transfer agent, EQT Corporation, then you are a shareholder of record. As a shareholder of record, you may vote in person at the annual meeting or vote by proxy. Whether or not you plan to attend the annual meeting, we urge you to vote by proxy by phone or online as instructed below or if you received printed proxy materials, to fill out and return the enclosed proxy card, to ensure your vote is counted.

If you are a shareholder of record, the Notice is being sent to you directly.

*Beneficial Owner: Shares Registered in the Name of a Broker or Bank*

If on March 3, 2026 your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in "street name" and a voting instruction form being forwarded to you by that organization. The organization holding your account is considered to be the shareholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the shareholder of record, you may not vote your shares in person at the annual meeting unless you request and obtain a valid proxy from your broker or other agent.

***How can I view the shareholder list?***

A list of the shareholders entitled to vote at the annual meeting will be available for inspection upon request of any shareholder for any purpose germane to the annual meeting at our U.S. subsidiary's office at 215 Church Street, New Haven, CT 06510, during the ten days prior to the annual meeting, during ordinary business hours. To make arrangements to review the list prior to the annual meeting, shareholders should contact the Corporate Secretary at +1 (401) 274-9200 or Douglas.Gray@troutman.com.

***On what matters am I voting?***

The following matters are scheduled for a vote:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Election of Directors*:

*Beneficial Owner: Shares Registered in the Name of Broker or Bank*

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a voting instruction form with these proxy materials from that organization rather than from Biohaven. Simply complete and mail the voting instruction form to ensure that your vote is counted. Alternatively, you may vote by phone or online as instructed by your broker or bank. To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy form.

***How many votes do I have?***

On each matter to be voted upon, holders of our common shares have one vote for each common share owned as of March 3, 2026.

***What happens if I do not vote?***

*Shareholder of Record: Shares Registered in Your Name*

If you are a shareholder of record and do not vote by completing your proxy card online, by mail, by phone or in person at the annual meeting, your shares will not be voted.

*Beneficial Owner: Shares Registered in the Name of Broker or Bank*

If you are a beneficial owner and do not instruct your broker, bank, or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the NYSE deems the particular proposal to be a "routine" matter. Brokers and nominees can use their discretion to vote "uninstructed" shares with respect to matters that are considered to be "routine," but not with respect to "non-routine" matters. Under the rules and interpretations of the NYSE, "non-routine" matters are matters that may substantially affect the rights or privileges of shareholders, such as mergers, shareholder proposals, elections of directors (even if not contested), executive compensation (including any advisory shareholder votes on executive compensation, or advisory shareholder votes on the frequency of shareholder votes on executive compensation), and certain corporate governance proposals, even if management-supported. Accordingly, your broker or nominee may not vote your shares on Proposals 1(a), 1(b), 1(c), or 3 without your specific voting instructions, but may vote your shares on Proposal 2 even in the absence of your instruction.

***What if I return a proxy card or otherwise vote but do not make specific choices?***

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, "For" the election of all nominees for director, "For" the ratification of Ernst & Young LLP as the Company's independent registered public accounting firm for the year ending December 31, 2026 and "For" the non-binding proposal to approve the compensation of the Company's named executive officers. If any other matter is properly presented at the annual meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using their best judgment.

***Who is paying for this proxy solicitation?***

We will pay for the entire cost of soliciting proxies. In addition to the Notice and these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We will also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

***Can I change my vote after submitting my proxy?***

*Shareholder of Record: Shares Registered in Your Name*

Yes. You can revoke your proxy at any time before the final vote at the annual meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;You may grant a subsequent proxy by phone or online.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;You may submit another properly completed proxy card with a later date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;You may send a timely written notice that you are revoking your proxy to Biohaven's Corporate Secretary at c/o Biohaven Pharmaceuticals, Inc., 215 Church Street, New Haven, CT 06510.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;You may attend the annual meeting and vote in person. Simply attending the annual meeting will not, by itself, revoke your proxy.

Your most current proxy card or proxy submitted by phone or online is the one that is counted.

*Beneficial Owner: Shares Registered in the Name of Broker or Bank*

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

***When are shareholder proposals and director nominations due for next year's annual meeting?***

In accordance with the SEC's Rule 14a-8, to be considered for inclusion in next year's proxy materials, your proposal must be submitted in writing by November 13, 2026 to our Corporate Secretary at c/o Biohaven Pharmaceuticals, Inc., 215 Church Street, New Haven, CT 06510. If you wish to nominate an individual for election at, or bring business other than through a shareholder proposal before the 2027 annual meeting of shareholders, you must deliver your notice to our Corporate Secretary at the address above between December 29, 2026 and January 28, 2027, which is at least 90 days, but not more than 120 days, prior to the first anniversary of our 2026 Annual Meeting of Shareholders. Your notice to the Corporate Secretary must set forth information specified in our Memorandum and Articles of Association, including your name and address and the class and number of our shares that you beneficially own.

In addition to satisfying the foregoing requirements, to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than Biohaven's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than February 27, 2027.

If you propose to bring business before an annual meeting other than a director nomination, your notice must also include, as to each matter proposed, the following: (1) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting that business at the annual meeting and (2) any material interest you have in that business. If you propose to nominate an individual for election as a director, your notice must include, as to each person you propose to nominate for election as a director, the information required by our Amended and Restated Memorandum and Articles of Association and any other information concerning the proposed nominee as would be required to be disclosed in a proxy statement soliciting proxies for the election of that person as a director in an election contest (even if an election contest is not involved), or that is otherwise required to be disclosed pursuant to Section 14 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the rules and regulations promulgated under the Exchange Act, including the person's written consent to being named as a nominee and to serving as a director if elected. We may require any proposed nominee to furnish other information as we may reasonably require to determine the eligibility of the proposed nominee to serve as an independent director or that could be material to a reasonable shareholder's understanding of the independence, or lack of independence, of the proposed nominee.

For more information, and for more detailed requirements, please refer to our Amended and Restated Memorandum and Articles of Association filed as Exhibit 3.1 to our Current Report on Form 8-K filed with the Securities and Exchange Commission, or SEC, on October 3, 2022.

***How are votes counted?***

Votes will be counted by the inspector of election appointed for the annual meeting, who will separately count, (1) for each of the proposals to elect directors, votes "For," "Against" and any broker non-votes and abstentions, (2) with respect to the ratification of independent auditors, votes "For," "Against" and abstentions and (3) with respect to the Say-on-Pay vote, votes for "For," "Against" and any broker non-votes and abstentions. Broker non-votes will have the same effect as a vote "Against" the Say-on-Pay vote.

***What are "broker non-votes"?***

As discussed above, when a beneficial owner of shares held in "street name" does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed by the NYSE to be "non-routine," the broker or nominee cannot vote the shares. These unvoted shares are counted as "broker non-votes."

***How many votes are needed to approve each proposal?***

For Proposals 1(a), 1(b) and 1(c), the election of directors, any nominees receiving "For" votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the election of directors, and which did not abstain, will be elected. Only votes "For" or "Against" will affect the outcome with respect to these three proposals, and abstentions will have no effect. Broker non-votes will have no effect and will not be counted toward the vote total for the director nominees.

To be approved, Proposal 2, the ratification of Ernst & Young LLP as the Company's independent registered public accounting firm, must receive "For" votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the matter. Only votes "For" or "Against" will affect the outcome with respect to this proposal, and broker non-votes and abstentions will have no effect.

To be approved, Proposal 3, the Say-on-Pay vote, must receive "For" votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the matter. Only votes "For" or "Against" will

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

affect the outcome with respect to this proposal, and abstentions will have no effect. This Say-on-Pay vote is not binding on the Company, the compensation committee or the Board. However, the compensation committee and the Board will take into account the result of the vote when evaluating the effectiveness of our compensation principles and practices.

***What is the quorum requirement?***

A quorum of shareholders is necessary to hold a valid meeting. A quorum is present if shareholders holding at least 50% of the votes of the shares entitled to vote on the matters to be considered at the annual meeting are present in person or represented by proxy. On the record date of March 3, 2026, there were 150,420,584 common shares outstanding and entitled to vote.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) online, by mail, by phone or if you vote in person at the annual meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, either the chair of the annual meeting or the holders of a majority of shares present at the annual meeting in person or represented by proxy may adjourn the annual meeting to another date.

***How can I find out the results of the voting at the annual meeting?***

Preliminary voting results will be announced at the annual meeting. In addition, final voting results will be published in a Current Report on Form 8-K.

The proxy statement, the Annual Report on Form 10-K for the year ended December 31, 2025 (the "Annual Report") and annual report to shareholders are available at www.proxyvote.com.

**PROPOSALS 1(A), 1(B) AND 1(C)** 

**ELECTION OF DIRECTORS**

There are three directors in the class whose term of office expires in 2026, Michael T. Heffernan, Irina Antonijevic, M.D., Ph.D., and Robert J. Hugin. Mr. Heffernan, Dr. Antonijevic, and Mr. Hugin currently serve on the Board of Directors. If re-elected at the annual meeting, each of these nominees will serve until the 2029 annual meeting and until his or her successor has been duly elected and qualified, or, if sooner, until his or her death, resignation or removal. It is the Company's policy to invite and encourage all directors and nominees for director to attend the annual meeting. All of the members of our Board of Directors attended our 2025 annual meeting of shareholders.

Directors are elected by a majority of the votes of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors and which have not abstained from voting. Accordingly, for each of Proposals 1(a), 1(b) and 1(c), the nominee receiving "For" votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the election of directors, and which did not abstain, will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of each of the three nominees named below.

**If any of the nominees becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee that we propose.** Each person nominated for election has agreed to serve if elected. We have no reason to believe that any of the nominees will be unable to serve.

**NOMINEES FOR ELECTION FOR A THREE-YEAR TERM EXPIRING AT THE 2029 ANNUAL MEETING**

The following is a brief biography of each nominee for director and a discussion of the specific experience, qualifications, attributes or skills of each nominee that led the nominating and corporate governance committee to recommend that person as a nominee for director, as of the date of this proxy statement.

The nominating and corporate governance committee seeks to assemble a board that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and high-level management experience necessary to oversee and direct the Company's business. To that end, the nominating and corporate governance committee has identified and evaluated nominees in the broader context of the Board's overall composition, with the goal of recruiting members who complement and strengthen the skills of other members and who also exhibit integrity, collegiality, sound business judgment and other qualities that the nominating and corporate governance committee views as critical to effective functioning of the Board. The brief biographies below include information, as of the date of this proxy statement, regarding the specific and particular experience, qualifications, attributes or skills of each director or nominee that led the nominating and corporate governance committee to believe that nominee should continue to serve on the Board. However, each of the members of the nominating and corporate governance committee may have a variety of reasons why he or she believes a particular person would be an appropriate nominee for the Board, and these views may differ from the views of other members.

**INDEPENDENCE OF THE BOARD OF DIRECTORS**

The Board conducts an annual assessment of the independence of its members under relevant securities and other laws and regulations regarding the definition of "independent," including those set forth in pertinent NYSE rules, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that Dr. Bailey, Mr. Childs, Ms. Gregory, Mr. Hugin, Dr. Antonijevic and Mr. Heffernan, representing six of our eight directors, are "independent directors" as defined under NYSE rules. In making this determination, the Board found that none of these directors or nominees for director had a material or other disqualifying relationship with the Company.

**BOARD LEADERSHIP STRUCTURE: CHAIR AND LEAD INDEPENDENT DIRECTOR**

Our Board Chair is currently Dr. Coric, the Chief Executive Officer. Dr. Coric assumed the Chair position on September 28, 2022. In addition to the Chair, pursuant to our Corporate Governance Guidelines, the Board has a separate Lead Independent Director. Mr. Heffernan became the Lead Independent Director on September 28, 2022. The Lead Independent Director is responsible for coordinating the activities of the independent directors, and, in addition to the duties of all Board members, is responsible for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• working with the Chief Executive Officer to develop and approve a Board meeting schedule;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• working with the Chief Executive Officer to develop and approve Board meeting agendas;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• providing the Chief Executive Officer feedback on the quality, quantity, and timeliness of the information provided to the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• developing the agenda for and moderating executive sessions of the independent members of the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• presiding over Board meetings when the Chief Executive Officer is not present or when Board or Chief Executive Officer performance or compensation is discussed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• acting as the principal liaison between the independent members of the Board and the Chief Executive Officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• convening meetings of the independent directors as appropriate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• being available for consultation and direct communication with shareholders as deemed appropriate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• performing other duties as the Board may determine from time to time.

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

Accordingly, the Lead Independent Director has substantial ability to shape the work of the Board. We believe that the separation of the positions of Lead Independent Director and Chief Executive Officer reinforces the independence of the Board in its oversight of the business and affairs of the Company. In addition, we believe that having a Lead Independent Director creates an environment that is more conducive to objective evaluation and oversight of management's performance, increasing management accountability and improving the ability of the Board to monitor whether management's actions are in the best interests of the Company and our shareholders. As a result, we believe that having a Lead Independent Director can enhance the effectiveness of the Board as a whole.

**ROLE OF THE BOARD IN RISK OVERSIGHT**

One of the Board's key functions is informed oversight of the Company's risk management processes. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. In particular, the Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for the Company. Our audit committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The audit committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our internal audit function, and bears the primary responsibility for overseeing risks associated with our information systems and technology, including cybersecurity. Our nominating and corporate governance committee monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct. Our compensation committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board as quickly as possible. The Board has delegated to the Board Chair and the Lead Independent Director the responsibility of coordinating between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues.

**ANNUAL BOARD EVALUATIONS**

The nominating and corporate governance committee oversees an annual evaluation that is intended to determine whether the Board, its committees, and each member of the Board is functioning effectively, and to provide an opportunity to reflect upon, and improve, Board processes and their effectiveness. The nominating and corporate governance committee reviews each director's overall service to the Company, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair each director's independence. The nominating and corporate governance committee also takes into account the results of the Board's self-evaluation, which is conducted annually on a group and individual basis.

**INSIDER TRADING POLICY**

The Company has adopted an Insider Trading and Window Period Policy (the "Trading Policy") governing the purchase, sale, and/or other dispositions of the Company's securities by directors, officers and employees, as well as the Company itself, that are reasonably designed to promote compliance with insider trading laws, rules and regulations and NYSE listing standards. Purchases or sales of securities of the Company by the Company shall be made in compliance with applicable securities laws.

**PROHIBITION AGAINST HEDGING**

The Trading Policy also prohibits any employee, officer or director from engaging in short sales, transactions in put or call options, hedging transactions or other inherently speculative transactions with respect to the Company's stock at any time. However, the Trading Policy permits margin account transactions in Company stock and pledges of Company stock in connection with such transactions which are otherwise permitted under the Trading Policy and that are in compliance with applicable law.

**EQUITY OWNERSHIP POLICY**

To encourage the Company's directors and executive officers to maintain a significant ownership interest in the Company and align their interests with those of shareholders, the Company has adopted an equity ownership policy. The Company requires its directors and executive officers to have an equity ownership interest in the Company in accordance with the following schedule, in each case, measured as of January 1 of each year:

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

---

| | |
|:---|:---|
| Chief Executive Officer | 3x annual base salary and cash bonus |
| Other executive officers | 1x annual base salary and cash bonus |
| Non-employee directors | Not less than $1,000,000 in equity value |

---

The chief executive officer, other executive officers and non-employee directors were all in compliance with the equity ownership policy as of January 1, 2026.

Equity ownership interests that are counted towards meeting this requirement include: (1) common shares that are owned or are restricted with vesting subject only to time-based vesting (including those held through any Company-sponsored plan such as a qualified retirement plan and/or a supplemental executive retirement plan), which are each valued at fair market value, (2) vested options, which are valued at 100% of their net value, and (3) restricted stock units that are subject only to time-based vesting, which are valued at 70% of their value.

Executive officers and directors have three years after the executive officer's date of hire or promotion or the director's date of election to the Board, as applicable, to accumulate their respective ownership interest in compliance with these guidelines.

**MEETINGS OF THE BOARD OF DIRECTORS**

The Board met four times during the last fiscal year. Each Board member attended 75% or more of the aggregate number of meetings of the Board and of the committees on which he or she served, held during the portion of the last fiscal year for which he or she was a director or committee member. Additionally, all Board members were present at the Company's 2025 Annual General Meeting held on May 5, 2025, with five (5) members attending in person and three (3) attending via video conference.

NYSE rules require that the non-management directors of the board meet at regularly scheduled executive sessions, without management present, in order to empower the non-management directors to serve as a more effective check on management. During the last fiscal year, the Company's non-management directors met at the end of each in-person board meeting in executive session, without management present, followed by a meeting of independent directors only. As Lead Independent Director, Mr. Heffernan presided over these executive sessions.

**INFORMATION REGARDING COMMITTEES OF THE BOARD OF DIRECTORS**

The Board has three standing committees: an audit committee, a compensation committee, and a nominating and corporate governance committee. The following table provides membership and meeting information for the fiscal year ending December 31, 2025 for each of the Board committees.

\*&nbsp;&nbsp;&nbsp;&nbsp;Committee Chair.

Below is a description of each standing committee of the Board. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board has determined that each member of each committee meets the applicable NYSE rules and regulations regarding "independence," and each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.

***Compensation Committee***

Our compensation committee reviews and determines the compensation of our executive officers. Our compensation committee currently consists of Mr. Childs, Mr. Heffernan and Mr. Hugin. Our compensation committee consists solely of non-employee members of our Board as defined in Rule 16b-3 under the Exchange Act. Mr. Heffernan is the chair of the compensation committee. Our Board has determined that the composition of our compensation committee satisfies the applicable independence requirements under, and the functioning of our compensation committee complies with the applicable requirements of, the NYSE rules and SEC rules and regulations. We intend to continue to evaluate and intend to comply with all future requirements applicable to our compensation committee. The principal duties and responsibilities of our compensation committee include:

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;establishing and approving, and making recommendations to the Board regarding, performance goals and objectives relevant to the compensation of our chief executive officer, evaluating the performance of our chief executive officer in light of those goals and objectives and setting, or recommending to the full Board for approval, the chief executive officer's compensation, including incentive-based and equity-based compensation, based on that evaluation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;setting the compensation of our other executive officers, based in part on recommendations of the chief executive officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;exercising administrative authority under our stock plans and employee benefit plans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;establishing policies and making recommendations to our Board regarding director compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;reviewing and discussing with management the compensation discussion and analysis that we may be required from time to time to include in SEC filings; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;preparing a compensation committee report on executive compensation as may be required from time to time to be included in our annual proxy statements or Annual Reports on Form 10-K filed with the SEC.

During 2025, the compensation committee met four times and expects to meet an average of once every quarter in 2026 and with greater frequency if necessary. The agenda for each meeting is usually developed by the chair of the compensation committee, in consultation with our Chief Executive Officer. The compensation committee meets regularly in executive session, without management present. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the compensation committee to make presentations, to provide financial or other background information or advice or to otherwise participate in compensation committee meetings, including the Company's compensation consultant, Aon's Human Capital Solutions practice ("Aon"). The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the compensation committee regarding his compensation or individual performance objectives. The charter of the compensation committee grants the compensation committee full access to all books, records, facilities and personnel of the Company. In addition, under its charter, the compensation committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the compensation committee considers necessary or appropriate in the performance of its duties. The compensation committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the committee. In particular, the compensation committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultants' reasonable fees and other retention terms. Under the charter, the compensation committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the compensation committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and NYSE, that bear upon the adviser's independence; however, there is no requirement that any adviser be independent.

The compensation committee is governed by a written Compensation Committee Charter approved by our Board of Directors. The charter is available on our website at www.biohaven.com under the links "Investors—Corporate Governance—Governance Documents—Compensation Committee Charter." We will also provide a printed copy of the charter to shareholders upon request.

*Compensation Committee Interlocks and Insider Participation* 

During fiscal year 2025, none of Messrs. Childs, Heffernan or Hugin, the current members of the compensation committee was an officer or employee of the Company or its subsidiaries or had any relationship with the Company requiring disclosure as a related party transaction under applicable rules of the SEC. During fiscal year 2025, none of our executive officers served as a member of the compensation committee of another entity, one of whose executive officers served on our compensation committee; none of our executive officers served as a director of another entity, one of whose executive officers served on our compensation committee; and none of our executive officers served as a member of the compensation committee of another entity, one of whose executive officers served as a member of our Board.

***Nominating and Corporate Governance Committee***

Our nominating and corporate governance committee consists of four directors, Dr. Bailey, Mr. Hugin, Dr. Antonijevic and Mr. Heffernan. Dr. Bailey is the chair of the nominating and corporate governance committee. Our Board has determined that each member of our nominating and corporate governance committee satisfies the applicable independence requirements of the NYSE and that the functioning of our nominating and corporate governance committee otherwise complies with the applicable requirements of, the NYSE standards and SEC rules and regulations. The nominating and corporate governance committee's responsibilities include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;assessing the need for new directors and identifying individuals qualified to become directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;recommending to the Board the persons to be nominated for election as directors and to each of the Board's committees;

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;assessing individual director performance, participation and qualifications;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;developing and recommending to the Board corporate governance principles;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;monitoring the effectiveness of the Board and the quality of the relationship between management and the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;overseeing an annual evaluation of management's and the Board's performance; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;reviewing the Company's charter and other policies.

The nominating and corporate governance committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements and having the highest personal integrity and ethics. The nominating and corporate governance committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of the Company's shareholders. However, the nominating and corporate governance committee retains the right to modify these qualifications from time to time. Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of the Company and the long-term interests of shareholders. In conducting this assessment, the nominating and corporate governance committee typically considers such factors as it deems appropriate, given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability.

In the case of incumbent directors whose terms of office are set to expire, the nominating and corporate governance committee reviews these directors' overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors' independence. The nominating and corporate governance committee also takes into account the results of the Board's self-evaluation, which is conducted annually on a group and individual basis. In the case of new director candidates, the nominating and corporate governance committee also determines whether the nominee is independent for NYSE purposes, which determination is based upon applicable NYSE rules, applicable SEC rules and regulations and the advice of counsel, if necessary. The nominating and corporate governance committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The nominating and corporate governance committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The nominating and corporate governance committee meets to discuss and consider the candidates' qualifications and then selects a nominee for recommendation to the Board by majority vote.

The nominating and corporate governance committee will consider director candidates recommended by shareholders consistent with the requirements of our organization documents. The nominating and corporate governance committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a shareholder. Shareholders who wish to recommend individuals for consideration by the nominating and corporate governance committee to be nominated by the committee for election to the Board may do so by delivering a written recommendation to the nominating and corporate governance committee at the following address: Corporate Secretary, Biohaven Ltd., c/o Biohaven Pharmaceuticals, Inc., 215 Church Street, New Haven, CT 06510. Shareholders seeking to nominate a candidate for election to the Board must submit a timely and compliant notice in writing to the secretary at the same address, in accordance with the procedures referenced in these proxy materials under "Questions and Answers About These Proxy Materials and Voting — When are shareholder proposals and director nominations due for next year's annual meeting?"

The nominating and corporate governance committee has oversight of our sustainability strategy and risk management. Our cross-functional Sustainability Working Group is comprised of senior executives and reports to the Board and nominating and corporate governance committee at least annually. Together with the working group, the Company has a Chief Talent & Sustainability Officer whose role is to promote accountability and coordinate our sustainability efforts across the organization.

The nominating and corporate governance committee met four times in 2025. The nominating and corporate governance committee is governed by a written nominating and corporate governance committee charter approved by our Board of Directors. The charter is available on our website at www.biohaven.com under the links "Investors—Corporate Governance—Governance Documents—Nominating and Corporate Governance Committee Charter." We will also provide a printed copy of the charter to shareholders upon request.

**SHAREHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS**

The Board has adopted a formal process by which shareholders may communicate with the Board or any of its directors. Shareholders who wish to communicate with the Board may do so by sending written communications addressed to the Board or the director in care of Biohaven Ltd., c/o Biohaven Pharmaceuticals, Inc., 215 Church Street, New Haven, CT 06510, Attn: Corporate Secretary. Each communication must set forth the name and address of the shareholder on whose behalf the communication is sent and the number and class of shares of our share capital that are owned beneficially by the shareholder as of the date of the communication.

These communications will be reviewed by our Corporate Secretary, who will determine whether they should be presented to the Board. The purpose of this screening is to allow the Board to avoid having to consider communications that contain advertisements or solicitations or are unduly hostile, threatening or similarly inappropriate. All communications directed to the audit committee in accordance with our Open Door Policy for Reporting Complaints Regarding Accounting and Auditing Matters that relate to questionable accounting or auditing matters involving the Company will be promptly and directly forwarded to the audit committee.

Any interested person may communicate directly with the non-management directors. Persons interested in communicating directly with the non-management directors regarding their concerns or issues may do so by addressing correspondence to a particular director, or to the non-management directors generally, in care of Biohaven Ltd., c/o Biohaven Pharmaceuticals, Inc., 215 Church Street, New Haven, CT 06510. If no particular director is named, letters will be forwarded, depending upon the subject matter, to the chair of the audit committee, compensation committee or nominating and corporate governance committee.

**CODE OF BUSINESS CONDUCT AND ETHICS FOR EMPLOYEES, EXECUTIVE OFFICERS AND DIRECTORS**

We have adopted a Code of Business Conduct and Ethics, or the Code of Conduct, applicable to all of our employees, executive officers and directors. The Code of Conduct is available on our website at www.biohaven.com under the links "Investors—Corporate Governance—Governance Documents—Code of Conduct." The nominating and corporate governance committee of our Board is responsible for overseeing the Code of Conduct and must approve any waivers of the Code of Conduct for employees, executive officers and directors. We plan to disclose any amendments to the Code of Conduct, or any waivers of its requirements for which disclosure is required, on our website within the time period required by the SEC.

**CORPORATE GOVERNANCE GUIDELINES**

The Board has documented the governance practices followed by the Company by adopting Corporate Governance Guidelines to assure that the Board will have the necessary authority and practices in place to review and evaluate the Company's business operations as needed and to make decisions that are independent of the Company's management. The guidelines are also intended to align the interests of directors and management with those of the Company's shareholders. The Corporate Governance Guidelines set forth the practices the Board intends to follow with respect to board composition and selection, board meetings and involvement of senior management, Chief Executive Officer performance evaluation and succession planning, and board committees and compensation. The Corporate Governance Guidelines are available on our website at www.biohaven.com under the links "Investors—Corporate Governance—Governance Documents—Corporate Governance Guidelines."

**PROPOSAL 2 RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS**

The audit committee of the Board has selected Ernst & Young LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the shareholders at the annual meeting.

Ernst & Young LLP has audited the Company's financial statements since its formation in May 2022. The Company has furnished Ernst & Young LLP with a copy of the disclosures under this Proposal 2. Representatives of Ernst & Young LLP are expected to be present at the annual meeting. However, there is a possibility that they may not be able to attend the annual meeting. If they are able to attend the annual meeting, they will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither the Company's Amended and Restated Memorandum and Articles of Association nor other governing documents or law require shareholder ratification of the selection of Ernst & Young LLP as the Company's independent registered public accounting firm. However, the audit committee is submitting the selection of Ernst & Young LLP to the shareholders for ratification as a matter of good corporate practice. If the shareholders fail to ratify the selection, the audit committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the audit committee in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of the Company and its shareholders.

To be approved, Proposal 2, the ratification of Ernst & Young LLP as the Company's independent registered public accounting firm, must receive "For" votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the matter. Abstentions will have no effect on the proposal.

**PRINCIPAL ACCOUNTANT FEES AND SERVICES**

The following table represents aggregate fees billed to the Company for services provided for the fiscal years ended December 31, 2025 and 2024 by Ernst & Young LLP, the Company's independent registered public accounting firm for the fiscal year ended December 31, 2024 and 2023, respectively.

All fees described above were pre-approved by the audit committee.

**PRE-APPROVAL POLICIES AND PROCEDURES**

The audit committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by the Company's independent auditors. The audit committee generally pre-approves specified services in the defined categories of audit services, audit-related, tax and other services up to specified amounts. Pre-approval may also be given as part of the audit committee's approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the audit committee's members, but the decision must be reported to the full audit committee at its next scheduled meeting.

**PROPOSAL 3**

**NON-BINDING ADVISORY VOTE ON THE COMPENSATION**

**OF THE COMPANY'S NAMED EXECUTIVE OFFICERS**

In accordance with the requirements of Section 14A of the Exchange Act, we are providing our shareholders with a non-binding advisory vote commonly referred to as a "Say-on-Pay" vote on the compensation of our named executive officers ("NEOs"), as described in the Compensation Discussion and Analysis section, the tabular disclosure regarding such compensation and the accompanying narrative disclosure set forth in this Proxy Statement. Section 14A of the Exchange Act requires us to hold the Say-on-Pay vote at least once every three years. Following the recommendation of our shareholders at our 2024 Annual Meeting, the Board has chosen to hold the Say-on-Pay vote every year.

We encourage you to read the Compensation Discussion & Analysis, which describes how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives, as well as the Summary Compensation Table and related compensation tables and narrative disclosure, which provide detailed information on the compensation of our NEOs. Our Board and compensation committee believe that the policies and procedures articulated in the Compensation Discussion & Analysis are effective in achieving our goals and the compensation of our NEOs reported in this Proxy Statement has supported and contributed to our success.

Although the results of the Say-on-Pay vote will not be binding, we value highly input from and engagement with our shareholders. Our Board and compensation committee will review the results of this Say-on-Pay vote and consider the outcome of the vote when evaluating the effectiveness of our compensation principles and practices. To be approved, Proposal 3, the Say-on-Pay vote, must receive "For" votes from the holders of a majority of shares present in person or represented by proxy and entitled to vote on the matter. Abstentions will have no effect on the proposal.

**THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION OF THE COMPANY'S NAMED EXECUTIVE OFFICERS.**

**SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT**

The following table sets forth the beneficial ownership of our voting securities as of March 3, 2026 for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each person, or group of affiliated persons, who is known by us to beneficially own more than 5% of any class of our voting securities, which consist of our common shares;

In addition, the rules include common shares issuable pursuant to the exercise of stock options that are exercisable on or before May 2, 2026, which is 60 days after March 3, 2026. These shares are deemed to be outstanding and beneficially owned by the person holding those stock options but not outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

Ltd. became an independent, publicly traded company as of October 3, 2022, and commenced regular way trading under the symbol "BHVN"' on the New York Stock Exchange (the "NYSE") on October 4, 2022. More information on the Separation can be found in Note 1 to our audited consolidated financial statements included in the Annual Report. The Company is now advancing its innovative portfolio of therapeutics, leveraging its proven drug development experience and multiple, proprietary drug development platforms.

**EXECUTIVE COMPENSATION PROGRAM** 

In line with our guiding principles described above, the objectives of our compensation program are to attract, retain and motivate our executive officers to meet our long-term goals, and to align the interests of our executive officers with those of the Company's shareholders. To achieve our goals, we provide appropriate levels of risk and reward, assessed on a relative basis to our peers at the executive levels within the Company and in proportion to individual contribution and performance. We establish appropriate incentives for management to further the Company's long-term strategic goals and avoid emphasis on increase in short-term market value.

The compensation committee of our Board (the "compensation committee") reviews compensation annually for all employees, including our executives. In determining recommendations to make to the independent members of the Board regarding the setting of executive base salaries, annual bonuses and bonus opportunities, and granting equity awards for our executive officers, the compensation committee considers compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, and our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our shareholders and to promote a long-term commitment to the Company. We consider the executive compensation of our peers in setting our executive pay levels and make adjustments to account for personal experience, performance and internal equity. In making our annual equity awards, grants are sized after evaluating and considering the Company's performance over the fiscal year, each executive's individual contributions to our accomplishments over the year (based on the executive's and the CEO's assessment of their performance) and the size of the award each executive received in the prior fiscal year.

***Compensation Committee Role and Process***

The compensation committee makes most of the significant adjustments to annual compensation, determine bonus and equity awards and establish new performance objectives at one or more meetings held during the first quarter of the year. The compensation committee will also consider matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of our compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year.

Independent members of our Board determine our executives' compensation after receiving recommendations from our compensation committee. The compensation committee consists of three members of the Board, and each member of the compensation committee is independent (as determined under the independence requirements of the New York Stock Exchange). The compensation committee's executive compensation duties and policies include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Reviewing and approving corporate goals and objectives that reinforce the Company's long-term strategic goals<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Approving, and recommending to the independent members of the Board for approval, levels of executive compensation<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Establishing policies with respect to equity compensation arrangements, including compensation plans and programs advisable for the Company<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Reviewing regional and industry-wide compensation practices and trends to assess the adequacy and competitiveness of the Company's compensation practices<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Evaluating the efficacy of the Company's compensation policy and strategy in achieving expected benefits to the Company and otherwise furthering the compensation committee's policy <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Implementing and administering the Company's clawback policy<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Reviewing and approving the terms of any NEO employment arrangements, severance arrangements, change in control protections and any other compensatory arrangements<br>

Each year, our compensation committee typically reviews and discusses management's proposed compensation for all executives. The CEO meets with the compensation committee to review the compensation levels for the Company's executive-level officers (other than our CEO) as well as the overall goals for the Company and individuals. The compensation committee solicits and considers evaluations and recommendations submitted to the compensation committee by the Chief Executive Officer with respect to individual employee performance. Based on those discussions and after receiving recommendations from the CEO and the compensation committee, our Board, in its discretion and without members of management present, discusses and ultimately approves the compensation of our executive officers.

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the compensation committee, which determines any adjustments to his compensation as well as awards to be granted.

The independent members of our Board make all final compensation and equity award decisions regarding our NEOs after receiving recommendations from our compensation committee. Our review process considers company performance, and the contributions of various individuals, and emphasizes pay for performance principles to motivate and reward exceptional performance, with the goal of maximizing shareholder value. For all executives and directors as part of its deliberations, the compensation committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director share ownership information, stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels and recommendations of the compensation consultant, including analyses of executive and director compensation paid at other companies identified by the consultant to be comparable to us. The compensation committee does not consider severance benefits when making recommendations to the independent members of the Board related to setting other components of compensation.

*Role of Independent Compensation Consultant*

The compensation committee has engaged an independent compensation consulting firm, Aon's Human Capital Solutions practice, a division of Aon ("Aon"), since October 2022 to help ensure that our compensation practices are aligned with best market practices and shareholder value. In 2025, the compensation committee again retained Aon to evaluate our executive compensation program. Aon's engagement for our 2025 fiscal year included: attending compensation committee meetings, assisting the compensation committee with the selection of a peer group of companies for benchmarking purposes, analysis of our existing executive compensation programs, including our equity incentive plan and equity-based award grant practices, and analysis of our director compensation policy. Aon serves at the pleasure of the compensation committee rather than management, and Aon's fees are approved by the compensation committee. The compensation committee has assessed the independence of Aon pursuant to SEC and NYSE rules and concluded that no conflict of interest exists that would prevent Aon from serving as an independent consultant to the compensation committee.

***Use of Peer Group Data***

Our compensation committee, in conjunction with management, uses competitive market data from surveys and reports prepared by Aon. This peer group is used by the compensation committee in determining recommendations to make to the independent board members regarding our incentive plans and total compensation.

We consider market survey data from a peer group of companies that have similar revenue size, market capitalization, headcount, brand value, products, or markets, or with which we compete for executive talent. We established a peer group of publicly traded companies in the biopharmaceutical sector generally based on a balance of the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• companies with a therapeutic focus on neurology and/or immunology;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• companies with comparable market capitalizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• companies with comparable trailing twelve month revenues; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• companies that are generally in the clinical development-stage and in Phase 3 trials.

For purposes of setting 2025 compensation, the compensation committee used the following peer group:

------

|:---|:---|:---|

| &nbsp;&nbsp;Cogent Biosciences | &nbsp;&nbsp;Neumora Therapeutics | |
| &nbsp;&nbsp;Crinetics Pharmaceuticals | &nbsp;&nbsp;Rhythm Pharmaceuticals | |

---

Changes to the peer group relative to the peer group used by the compensation committee to set 2024 compensation, as well as determine equity awards granted in January 2025 in respect of 2024 performance, were made to better reflect comparable market capitalization and stage of development.

**2025 EXECUTIVE COMPENSATION PROGRAM IN DETAIL**

Our executive compensation program is aligned with our long-term goals and is intended to attract and retain top talent, reward business performance and maximize shareholder value. Our view of performance reflects the individual's ability to execute our business objectives in a collaborative and goal-driven environment. Our total compensation program for NEOs is competitive with our peer companies and is comprised of the following key compensation elements:

---

| | | |
|:---|:---|:---|
| **Element** | **Form of Compensation** | **Objective** |
| **Annual Base Salary** | Cash | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Reflects the executive's abilities, experience, roles, and responsibilities |
| **Annual Bonus** | Cash | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Performance-based annual cash bonus based on Company financial results and individual performance |
| **Long-Term Incentive** | Stock Options & RSUs | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ Aligns the interests of executives with those of shareholders  |
| **Severance Protection** | Cash Severance, Employee Benefits, and Vesting of Equity-Based Awards (if applicable) | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ All of our NEOs are eligible for post-termination severance payments and benefits under their employment arrangements to attract and retain top talent by providing financial security and clarity around outcomes if their employment ends due to events outside of their control, such as a change in control of the Company |

---

The compensation committee reviews and recommends to the Board the appropriate target compensation mix for each NEO, taking into account the executive's success in achieving their individual performance goals and objectives and the corporate performance goals and objectives that are relevant to the executive officer. We do not apply fixed ratios or formulas, or rely solely on market data or quantitative measures for allocating compensation among salary, annual cash incentive awards and long-term incentive equity grants. Instead, the compensation committee and the Board exercise judgment to establish a total compensation program for each NEO that is a mix of current, short- and long-term incentive compensation, and cash and non-cash compensation, that the compensation committee and Board believe is appropriate to achieve the goals of our executive compensation program and our corporate objectives.

***Annual Base Salary***

Annual base salaries are intended to provide a fixed component of compensation to our NEOs, reflecting their skill sets, experience, roles and responsibilities. Our compensation committee is generally responsible for reviewing and recommending the appropriate base salary for executives to the independent members of the Board for approval after taking into consideration input received from its independent compensation consultant and management.

Base salaries are generally determined, approved and reviewed periodically by our Board in order to compensate our NEOs for the satisfactory performance of duties to our company, and to align with the market.

The following table presents the base salaries for each of our NEOs during 2025, which became effective on January 1, 2025. In determining the base salary increases set forth in the table below, the compensation committee, with assistance from AON, considered the Company's 2024 performance, the Company's stock and valuation performance in 2024 compared to the XBI and S&P benchmarks, and the Company's cash compensation philosophy of targeting the 50th percentile of the 2024 peer group with the ability to flex up on bonuses and/or equity awards to reward outstanding performance by the Company. Ultimately the compensation committee determined that the Company's 2024 performance

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

was extraordinary, and the independent members of the Board approved the compensation committee's recommended increases to the 2025 base salary levels of the NEOs in order to bring their base salaries generally in line with the 50th percentile of the peer group.

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**Name** | **2025 Annual Base Salary ($)** | &nbsp;&nbsp;**Increase from 2024** |
| Vlad Coric, M.D. | $920400 | 4.0% |
| Matthew Buten | $596232 | 4.0% |
| Kimberly Gentile | $508879 | 4.0% |
| Bruce Car, Ph.D. | $536190 | 4.0% |

---

***Annual Cash Bonuses***

We seek to motivate and reward our executive officers for achievements relative to our corporate goals and expectations for each fiscal year. Each of our NEOs is eligible to receive an annual cash bonus dependent on individual and corporate performance.

Each of our NEOs has a target bonus opportunity specified in their respective employment arrangement with Biohaven Pharmaceuticals, Inc., defined as a percentage of their annual salary. For 2025, the target bonus opportunities for our NEOs were as follows:

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Name** | &nbsp;&nbsp;**2025 Target Annual Cash Bonus (% of Salary)** |
| Vlad Coric, M.D. | 75% |
| Matthew Buten | 50% |
| Kimberly Gentile | 45% |
| Bruce Car, Ph.D. | 45% |

---

The compensation committee reviewed the Company's 2025 performance and the individual performance of each NEO with Dr. Coric (Dr. Coric does not participate in discussions on his own bonus or salary), considering individual contributions and accomplishments during the year and the 2025 performance metrics established by the compensation committee, and recommended to the independent Board the bonus amounts to be paid to each NEO for 2025 performance. The compensation committee reviewed Dr. Coric's 2025 performance and recommended his bonus amount to the Board. The independent members of the Board, following the recommendation of the compensation committee, determined to pay the following bonuses to each of our NEOs in February 2026:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**Name** | **2025 Actual Annual Cash Bonus ($)** | &nbsp;&nbsp;**Percentage Above (Below) Target Bonus** |
| Vlad Coric, M.D. | $460200 | (33)% |
| Matthew Buten | $238493 | (20)% |
| Kimberly Gentile | $228996 | —% |
| Bruce Car, Ph.D. | $241286 | —% |

---

In determining the amount of actual annual cash bonuses paid to our NEOs for 2025, the compensation committee reviewed market data provided by its independent consultant, including bonus opportunities and actual payouts for comparable roles at peer companies, and considered the relationship between multi-year company performance and cumulative NEO compensation. The Company's philosophy of cash compensation targets the 50th percentile of the peer group with the ability to flex up on cash bonus awards and equity to reward outstanding performance, innovation, and efficiency by the NEOs contributed to the Company's success in meeting the performance metrics established by the compensation committee for 2025. The compensation committee noted that the NEOs and the Company had achieved all of the target objectives set forth in the 2025 performance metrics, but also recognized that the failure to obtain FDA approval of the new drug application for spinocerebellar ataxia had a material adverse effect on the Company's stock value. The Committee determined that this material adverse effect should be taken into account when deciding the 2025 actual cash bonus payments and, as a result, approved bonus payments below the 2025 Target Bonus amounts. Based on this assessment, the compensation committee recommended that the discretionary annual merit-based cash bonuses earned by NEOs be positioned between the 75th to 90th percentile as compared to the market, with the amount of an NEO's bonus within this range fluctuating based on the individual performance of each NEO. The compensation committee differentiated payouts by NEO, taking into account each executive's role, scope of responsibility, and individual

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

performance against individual 2025 objectives. Executives who made exceptional contributions to the achievement of our 2025 goals received bonuses toward the upper end of the range, while others received amounts closer to the lower end.

***Long-Term Incentives***

Our equity-based incentive awards are designed to align our executives' interests with those of our shareholders. Our compensation committee is responsible for reviewing and recommending equity grants to the independent members of the Board for their approval. Vesting of equity awards is generally tied to continuous service with the Company over the vesting schedule and serves as an additional retention measure. Additional grants may occur periodically in order to specifically incentivize executives with respect to achieving certain corporate goals or to reward executives for exceptional performance.

All of the Company's currently outstanding equity award grants to executives have been made in the form of stock options and RSUs. Stock options and RSUs are designed to align the interests of the Company's executives with those of shareholders by encouraging executives to enhance the value of the Company and, hence, the price of our common shares. Our stock options are granted with a per share exercise price equal to no less than the fair market value of a common share on the date of the grant. The structure of the equity program recommended by the compensation committee to the independent members of the Board (including the mix of equity awards and the relative weight assigned to each type of award) is reviewed annually by the compensation committee and its independent compensation consultant, and aims to motivate sustainable stock price appreciation, promote executive retention, limit unnecessary risk-taking and minimize shareholder dilution, while remaining competitive with market practices for similarly situated companies.

When determining the equity awards granted to the NEOs, Dr. Coric reviews each NEOs' individual self-assessments of their own performance over the prior year, and then makes his own assessment of the performance and contributions of each NEO. Based on those assessments and on the Company's performance over the prior fiscal year, Dr. Coric recommends the equity awards to be granted to each NEO (other than himself) to the compensation committee. The compensation committee considers Dr. Coric's assessments and input and makes a final recommendation to the Board as to size of the equity grants to awarded to each NEO. The compensation committee reviews Dr. Coric's performance and recommends the size of his equity grant to the Board. When determining the size of the grants, the compensation committee also considers a number of other factors, including the Company's performance, individual performance, competitive market data as described in "Use of Peer Group Data" above, the NEO's position and responsibilities, and the Company's share performance. Our Board makes the final assessment of performance and has the ultimate authority to approve and award equity grants based on the compensation committee's recommendation, with input from the compensation consultant.

In determining the number of stock options granted to our NEOs in respect of 2025 performance, the committee and Board again considered the Company's performance in 2025, the Company's stock and valuation performance over the past year compared to the XBI and S&P benchmarks, the Company's philosophy of cash compensation targeted at the 50th percentile of the peer group with the ability to flex up on awards and/or equity to reward outstanding performance by the Company, the results of performance evaluations conducted by Aon, and the individual contributions by each NEO, based on the assessment of the CEO (other than with respect to his own performance, which was assessed by the compensation committee).

*Equity Grants in Respect of 2025 Performance*

In February 2026, the compensation committee recommended to the Board, after discussion with the CEO (other than with respect to his own pay), that annual equity grants in respect of 2025 performance in the form of stock options be made to our NEOs. The compensation committee determined that the grants of stock options in respect of 2025 performance would be made in the first quarter of 2026. In accordance with applicable SEC rules, these grants will be reflected in the Summary Compensation Table for 2026, the year in which they were granted.

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

The aggregate number of equity awards granted to each NEO on February 27, 2026 in respect of 2025 performance are shown in the following table:

---

| | | |
|:---|:---|:---|
| **Name** | **Number of Options Granted** | **Option Grant Date Fair Value** |
| Vlad Coric, M.D. | 550000 | $4236320 |
| Matthew Buten | 175000 | $1347920 |
| Kimberly Gentile | 175000 | $1347920 |
| Bruce Car, Ph.D. | 175000 | $1347920 |

---

The exercise price of the options was the fair market value of Biohaven shares on the applicable date of grant ($11.52). The options will vest in four equal installments, with one-quarter vesting on the date of the grant and each remaining one-quarter on the first, second and third anniversary of the applicable date of the grant, subject to the grantee's continued employment through each vesting date. The Board determined to grant options with the foregoing vesting schedule in order to incentivize future performance and reward current performance.

In order for the NEOs to realize any value from their option grants, the Company's share price must appreciate, thus aligning our executive's long-term economic interests with those of our shareholders.

*Equity Grants in Respect of 2024 Performance*

In November 2024, the compensation committee recommended to the Board, after discussion with the CEO (other than with respect to his own pay), that annual equity grants in respect of 2024 performance in the form of stock options and RSUs be made to our NEOs. The compensation committee determined that the grants of stock options and RSUs in respect of 2024 performance would be made in the first quarter of 2025. These grants are reflected in the Summary Compensation Table for 2025.

The aggregate number of equity awards granted to each NEO on January 5, 2025 in respect of 2024 performance are shown in the following table:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| **Name** | **Number of Options Granted** | **Option Grant Date Fair Value** | **Number of RSUs Granted** | **RSU Grant Date Fair Value** | **Total Grant Date Value** |
| Vlad Coric, M.D. | 343000 | $9900043 | 57000 | $2202480 | $12102523 |
| Matthew Buten | 104000 | $3001762 | 17000 | $656880 | $3658642 |
| Kimberly Gentile | 91000 | $2626542 | 15000 | $579600 | $3206142 |
| Bruce Car, Ph.D. | 112000 | $3232667 | 17000 | $734160 | $3966827 |

---

The exercise price of the options was the fair market value of Biohaven shares on the applicable date of grant ($38.64). The NEO's options and RSUs granted will vest in four equal installments, with one-quarter vesting on the date of the grant and each remaining one-quarter on the first, second and third anniversary of the applicable date of the grant, subject to the NEO's continued employment through each vesting date. The Board determined to grant options and RSUs with the foregoing vesting schedule in order to incentivize future performance and reward current performance.

***Trading Policy and Prohibition Against Pledging***

The Company has adopted the Trading Policy, which governs the purchase, sale, and/or other dispositions of the Company's securities by directors, officers and employees, as well as the Company itself, that are reasonably designed to promote compliance with insider trading laws, rules and regulations and NYSE listing standards.

The Trading Policy prohibits employees, officers and directors from engaging in transactions designed to limit or eliminate economic risks, including transactions involving short sales, options, puts, calls, hedging transactions or other derivative securities tied to the Company's common shares. Officers, directors and others subject to the reporting obligations under Section 16 of the Exchange Act are also prohibited from engaging in short-swing trading and are

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

required to abide by the restrictions on sales by control persons and the disclosure requirements related to such sales. In addition, pursuant to Regulation BTR under the Exchange Act, directors and executive officers are prohibited from, directly or indirectly, purchasing, selling or otherwise acquiring or transferring any equity security during any "blackout period" with respect to such equity security, if such director or executive officer acquires or previously acquired such equity security in connection with his or her service or employment as director or executive officer. For more information on the Trading Policy, see the section entitled "*Information Regarding the Board of Directors and Corporate Governance — Prohibition Against Hedging*."

***Policies and Practices Related to Certain Equity Grants***

Awards to newly hired employees are granted effective on the day the employee commences employment with Biohaven, and annual equity awards are typically granted in the first quarter in connection with regularly scheduled compensation committee meetings, in accordance with the Company's compensation cycle. Employee start dates are determined independent of the release of material nonpublic information, and based on availability and necessity.

The exercise price for an award of options will be equal to but not less than the closing market price of our common stock on the grant date. The compensation committee neither grants equity awards in anticipation of the release of material nonpublic information, nor is the timing of filings of material nonpublic information based on equity award grant dates.

***Clawback Policy***

The Company has adopted an Incentive Compensation Recovery Policy (the "Clawback Policy"), in accordance with the New York Stock Exchange listing requirements, which became effective August 8, 2023. In the event that the Company is required to prepare an accounting restatement, the Clawback Policy requires the recovery of certain erroneously awarded incentive-based compensation received by current and former executive officers of the Company during the three fiscal years preceding an accounting restatement. This includes the cancellation and/or reduction of outstanding awards and the return of shares and/or cash paid and/or gain realized from an award.

***Risk Consideration***

The Company has established executive compensation programs and practices that measure performance and are paid on both a short-term and long-term basis in order to ensure that our executives are not focused on short-term gains that may jeopardize or otherwise risk the long-term health of the Company. Based on the compensation committee's review in 2022, we concluded that our compensation program does not encourage excessive risk-taking and is not reasonably likely to have a material adverse effect on the Company.

**COMPENSATION COMMITTEE REPORT**

The compensation committee of the Board, on behalf of the Board, establishes and monitors the Company's overall compensation strategy to ensure that executive compensation supports the business objectives. In fulfilling its oversight responsibilities, the compensation committee reviewed and discussed with management the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K set forth in this proxy statement. This Compensation Committee Report shall not be deemed to be incorporated by reference into any filing made by the Company under the Securities Act of 1933 or the Exchange Act, notwithstanding any general statement contained in any such filing incorporating this proxy statement by reference, except to the extent the Company incorporates such Report by specific reference.

In reliance on the review and discussions referred to above, the compensation committee recommended to the Board that the Compensation Discussion and Analysis be incorporated in the Company's proxy statement to be filed in connection with the Company's 2026 annual meeting of shareholders.

(2)&nbsp;&nbsp;&nbsp;&nbsp;Dr. Coric is entitled to a lump sum severance payment of $350,000 under his employment agreement with Biohaven Ltd. if he is terminated or is not elected to his position. In addition, pursuant to his employment agreement with Biohaven Pharmaceuticals, Inc., if Dr. Coric is terminated without "Just Cause" or if he resigns for "Good Reason", in either case (x) not in connection with a change in control (each of which we refer to as a "Qualifying Termination"), he is entitled to receive severance payments equal to his then-current annual base salary rate for 15 months following termination and (y) within 12 months of a change in control (each of which we refer to as a "Qualifying CIC Termination"), he is entitled to receive severance payments equal to his then-current annual base salary rate plus an amount equal to 150% of his target bonus in equal monthly installments for 18 months following termination.

(3)&nbsp;&nbsp;&nbsp;&nbsp;Dr. Coric is entitled to a lump sum severance payment of $350,000 under his employment agreement with Biohaven Ltd. upon his termination due to death or disability. In addition, pursuant to his employment agreement with Biohaven Pharmaceuticals, Inc., if Dr. Coric is terminated due to death or disability, he is entitled to receive severance payments equal his then-current annual base salary rate for 15 months following termination. The amount of severance paid to Dr. Coric is reduced by any disability benefits received under Biohaven Pharmaceuticals, Inc.'s disability insurance policies. However, no such reduction is assumed for purposes of the table above.

(4) &nbsp;&nbsp;&nbsp;&nbsp;The amount reported represents the cost of continued health and life insurance coverage during the period for which the executive receives severance payments, pursuant to the executive's employment arrangement with Biohaven Pharmaceuticals, Inc. Dr. Coric and Mr. Buten would be entitled to payment of their premiums for continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985. However, (x) the cost of such coverage to the Company as of December 31, 2025 is reported in the table above and (y) neither Mr. Buten nor Dr. Car is entitled to receive continued life insurance coverage upon a Qualifying CIC Termination.

(5) &nbsp;&nbsp;&nbsp;&nbsp;All outstanding stock option and RSU awards granted under the 2022 Plan would vest upon a Change in Control (as defined in the 2022 Plan).

(6)&nbsp;&nbsp;&nbsp;&nbsp;Upon the applicable termination of employment, the NEO is entitled to full vesting of all outstanding equity awards pursuant to the respective NEO's employment arrangement.

(7)&nbsp;&nbsp;&nbsp;&nbsp;Mr. Buten is entitled to a lump sum severance payment of $350,000 under his employment agreement with Biohaven Ltd. if he is terminated from his position. Pursuant to his employment agreement with Biohaven Pharmaceuticals, Inc., if Mr. Buten experiences a Qualifying Termination, he is entitled to receive severance payments equal to 150% the sum of his then-current annual base salary plus annual target bonus, paid in equal installments for 18 months following his termination of employment. He would also be eligible to receive a pro-rata bonus payment for the year in which he is terminated, to be determined and made at the sole discretion of the Board, equal to his target bonus opportunity, if any, which would have been awarded to him had he remained employed for the applicable performance period. To account for this pro-rata bonus, the amount in the table above assumes Mr. Buten received his full 2025 target bonus. If Mr. Buten experiences a Qualifying CIC Termination, Mr. Buten will receive the same payments as above, as well as an additional amount equal to his target bonus, payable in equal installments over 12 months.

(8) Pursuant to his employment agreement with Biohaven Pharmaceuticals Inc., if Mr. Buten is terminated due to death or disability, he is entitled to receive severance payments equal to 150% the sum of his then-current annual base salary plus annual target bonus, paid in equal installments for 18 months following his termination of employment. He would also be eligible to receive a pro-rata bonus payment for the year in which he is terminated, to be determined and made at the sole discretion of the board, equal to his target bonus opportunity, if any, which would have been awarded to him had he remained employed for the applicable performance period. To account for this pro-rata bonus, the amount in the table above assumes Mr. Buten received his full 2025 target bonus. If the termination is due to disability, the amount of severance paid to Mr. Buten is reduced by any disability benefits Mr. Buten receives under Biohaven Pharmaceuticals, Inc.'s disability insurance policies. However, no such reduction is assumed for purposes of the table above.

(9)&nbsp;&nbsp;&nbsp;&nbsp;Ms. Gentile is entitled to receive severance payments equal to six months of her base salary following termination.

(10)&nbsp;&nbsp;&nbsp;&nbsp;Pursuant to his offer of employment with Biohaven Pharmaceuticals, Inc., if Dr. Car experiences a Qualifying Termination, he is entitled to receive severance payments equal to the sum of his base salary and target bonus, payable in substantially equal installments over twelve months following his termination of employment. He would also be eligible to receive a pro-rata bonus payment for the year in which he is terminated, to be

determined and made at the sole discretion of the board, equal to his target bonus opportunity, if any, which would have been awarded to him had he remained employed for the applicable performance period. To account for this pro-rata bonus, the amount in the table above assumes Dr. Car received his full 2025 target bonus. Dr. Car would also be eligible to receive these same benefits upon a termination due to death or disability; provided, that, if the termination is due to disability, the amount of severance paid to Dr. Car is reduced by any disability benefits Dr. Car receives under Biohaven Pharmaceuticals, Inc.'s disability insurance policies. However, no such reduction is assumed for purposes of the table above.

(11) Pursuant to his offer of employment with Biohaven Pharmaceuticals, Inc., if Dr. Car experiences a Qualifying CIC Termination, he is entitled to receive severance payments equal to the sum of his base salary and two times the amount of his target bonus, payable in substantially equal installments over twelve months following his termination of employment. He would also be eligible to receive a pro-rata bonus payment for the year in which he is terminated, to be determined and made at the sole discretion of the board, equal to his target bonus opportunity, if any, which would have been awarded to him had he remained employed for the applicable performance period. To account for this pro-rata bonus, the amount in the table above assumes Dr. Car received his full 2025 target bonus.

**2025 CEO Pay Ratio Disclosure**

We are providing the following information about the relationship of the annual total compensation of our median employee and the annual total compensation of Dr. Coric, our CEO, for the year ended December 31, 2025:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;The annual total compensation of our median employee was $529,257.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;The annual total compensation of Dr. Coric was $13,231,422.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;This represents a ratio of 25:1.

There were no changes in our employee population or compensation arrangements in 2025 that would significantly change the pay ratio disclosure. Accordingly, as permitted under the applicable SEC disclosure rules, we identified as our median employee the same median-paid employee selected for the 2024 CEO pay ratio disclosure. To identify our median employee, we used our entire U.S. employee population as of December 31, 2024 and measured compensation based on Box 1 Form W-2 earnings, which we annualized for any full-time or part-time employee who was not employed by the Company for the entire 2024 year. Box 1 Form W-2 earnings consists of wages, tips and other compensation, including equity awards. We believe that the use of Box 1 Form W-2 compensation that has been annualized for any full-time and part-time employees who were not employed for the entire year is a consistently applied compensation measure that reasonably reflects compensation for our employee population because it includes base pay and annual incentive compensation, which a significant majority of our employees receive.

When identifying our median employee, we included all of our employees, whether full-time or part-time, but excluded independent contractors such as individuals that we employ through an independent third-party. For part-time workers, we did not adjust base cash compensation to the equivalent for a full-time employee. As of December 31, 2024, we had 257 employees, with 250 based in the U.S. Item 402(u) of Regulation S-K provides an exemption for companies to exclude non-U.S. employees from the median employee calculation if non-U.S. employees in a particular jurisdiction account for five percent or less of the company's total number of employees. We applied the foregoing de minimis exemption when identifying the median employee by excluding the Company's seven non-U.S. employees who are located in Ireland and provided services to our Irish subsidiary.

After identifying the median employee based on the above methodology, we calculated 2025 annual total compensation for such employee using the same methodology that we use for our named executive officers set forth in the 2025 Summary Compensation Table. To calculate the ratio, we then divided Dr. Coric's annual total compensation, as reported in the Summary Compensation Table, by the median employee's annual total compensation.

We believe the ratio above is a reasonable estimate calculated in accordance with SEC requirements under Item 402(u) of Regulation S-K. Given the different methodologies, exclusions, estimates and assumptions other companies may use to calculate their respective CEO pay ratios, as well as differences in employment and compensation practices between companies, the estimated ratio reported above may not be comparable to that reported by other companies.

**PAY VERSUS PERFORMANCE** 

Pursuant to Section 953(a) of the Dodd-Frank Act and Item 402(v) of SEC Regulation S-K, we are providing the following information about the relationship between executive "compensation actually paid" (or "CAP") to the Company's principal executive officer ("PEO") and non-PEO named executive officers (the "Non-PEO NEOs"), and certain aspects of the financial performances of the Company. The Compensation Committee does not utilize CAP as the basis for making compensation decisions. For further information concerning our compensation philosophy and how we align executive compensation with our performance, please see our CD&A.

(1)&nbsp;&nbsp;&nbsp;&nbsp;At this time, given that we are a research and development company without revenue, we do not use any specific company-selected financial measures other than TSR for purposes of determining CAP. Similar to many companies in the biotechnology industry, our annual incentive objectives are generally tied to the Company's strategic and operational goals rather than financial goals. Accordingly, this disclosure does not present a Company-Selected Measure in the table above, nor a Tabular List of our most important financial metrics.

(2)&nbsp;&nbsp;&nbsp;&nbsp;Dr. Vlad Coric served as the PEO for 2025, 2024, 2023, and the period from the closing of the Separation on October 3, 2022 through December 31, 2022. Our Non-PEO NEOs for (i) 2025, 2024 and 2023 were Matthew Buten, Kim Gentile and Dr. Bruce Car, and (ii) 2022, for the period from the closing of the Separation on October 3, 2022 through December 31, 2022, were Matthew Buten and Dr. Bruce Car.

These amounts reflect the Summary Compensation Table Total with certain adjustments made in accordance with Item 402(v) and as described in footnote 4 below.

***Relationship between CAP and TSR***

The graph below illustrates the relationship between CAP for the PEO and Non-PEO NEOs and our TSR, and compares our TSR over the four most recently completed fiscal years to that of the S&P Biotechnology ETF over the same period. The four-year compensation history of the PEO and Average Non-PEO NEO shows that the disclosed CAP aligns with Biohaven's TSR which outperformed the S&P Biotechnology ETF TSR for 2022, 2023, and 2024. Biohaven's TSR and CAP values both declined in 2025, further illustrating the alignment of the two metrics. The TSR values are based on a $100 investment made on October 3, 2022. The CAP values are strongly influenced by Biohaven's stock price due to the significant portion of share-based incentive compensation in our executive compensation program, intended to align our executives' interests with those of our shareholders.

***Director Compensation Policy***

Our director compensation policy is intended to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors and to align our directors' interests with those of our shareholders. In developing the director compensation policy, the Company's compensation committee seeks input from its compensation consultant, Aon.

------

<u>[**Table of Contents**](#iaf3a69fffbab4fdcbd5a51583838bfc9_13)</u>

*Annual Cash Compensation*

Under our director compensation policy, we pay each of our non-employee directors a cash retainer for service on the Board and for service on each committee on which the director is a member. The chair of the Board and the chair of each committee receive an additional retainer for such service. These retainers are payable in arrears in four equal quarterly installments on the last day of each quarter, provided that the amount of such payment will be prorated for any portion of such quarter that the director is not serving on our Board. The retainers paid to non-employee directors for service on the Board and for service on each committee of the Board on which the director is a member are as follows, and are unchanged from the prior year:

---

| | |
|:---|:---|
| *Annual Board Service Retainer* |  |
| &nbsp;&nbsp;All non-employee directors  | $50000 |
| &nbsp;&nbsp;Non-executive Chair of the Board (in addition to non-employee director service retainer above)  | $35000 |
| *Annual Committee Member Service Retainer* |  |
| &nbsp;&nbsp;Member of the Audit Committee  | $10000 |
| &nbsp;&nbsp;Member of the Compensation Committee  | $10000 |
| &nbsp;&nbsp;Member of the Nominating and Corporate Governance Committee  | $7000 |
| *Annual Committee Chair Service Retainer* |  |
| &nbsp;&nbsp;Chair of the Audit Committee  | $25000 |
| &nbsp;&nbsp;Chair of the Compensation Committee  | $20000 |
| &nbsp;&nbsp;Chair of the Nominating and Corporate Governance Committee  | $10000 |

---

We also continue to reimburse our non-employee directors for reasonable travel and out-of-pocket expenses incurred in connection with attending our Board and committee meetings.

*Annual Equity Compensation*

The equity compensation set forth below is granted under the 2022 Plan. All stock options granted under this plan and the director compensation policy are nonstatutory stock options, with an exercise price per share equal to 100% of the fair market value of the underlying common shares on the date of grant, and a term of ten years from the date of grant (subject to earlier termination in connection with a termination of service as provided in the 2022 Plan).

***Initial Equity Grant***

Pursuant to our director compensation policy, each new non-employee director elected to the board will be automatically, and without further action by the Board or compensation committee of the Board, granted a stock option to purchase common shares with an aggregate grant date fair value of approximately $713,875, on the date of each new non-employee director's initial election to the Board (or, if such date is not a market trading day, the first market trading day thereafter). The initial stock option grants will vest as follows: 25% on grant and 25% on each of the following three anniversaries of grant, subject to the non-employee director's continuous service through each such vesting date.

***Annual Equity Grant***

On the date of each annual shareholder meeting, each non-employee director who continues to serve as a non-employee member after the annual shareholder meeting of the Board will automatically, and without further action by the Board or compensation committee of the Board, be granted a stock option to purchase common shares with an aggregate grant date fair value of $485,944. These stock options will vest in full on the earlier of (a) the first anniversary of the applicable annual shareholder meeting at which the option was granted or (b) the date of the annual shareholder meeting following the annual shareholder meeting at which the option was granted, in each case subject to the non-employee director's continuous service through such vesting date.

The Board determined that the equity grants should have a set fair market value to better align with market practice and to ensure that no non-employee director, as a result of the volatility in our stock price, receives equity compensation that, when aggregated with annual cash compensation, exceeds the $1,000,000 limit set forth in the 2022 Plan. In order to comply with this limit, the aggregate grant date fair value of the annual equity grant or initial equity grant may be reduced in a given year.

**TRANSACTIONS WITH RELATED PERSONS**

**RELATED-PERSON TRANSACTIONS POLICY AND PROCEDURES**

We have adopted a written Related Person Transaction Policy that sets forth our procedures for the identification, review, consideration and approval or ratification of related person transactions. For purposes of our policy only, a related person transaction is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we and any related person are, were or will be participants in which the amount involved exceeds $120,000. Transactions involving compensation for services provided to us as an employee or director are not covered by this policy. A related person is any executive officer, director or beneficial owner of more than 5% of any class of our voting securities, including any of their immediate family members and any entity owned or controlled by such persons.

Under the policy, if a transaction has been identified as a related person transaction, including any transaction that was not a related person transaction when originally consummated or any transaction that was not initially identified as a related person transaction prior to consummation, our management must present information regarding the related person transaction to our audit committee, or, if audit committee approval would be inappropriate, to another independent body of our Board, for review, consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to us of the transaction and whether the transaction is on terms that are comparable to the terms available to or from, as the case may be, an unrelated third party or to or from employees generally. Under the policy, we will collect information that we deem reasonably necessary from each director, executive officer and, to the extent feasible, significant shareholder to enable us to identify any existing or potential related person transactions and to effectuate the terms of the policy. In addition, under our Code of Business Conduct and Ethics, our employees and directors have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest. In considering related person transactions, our audit committee, or other independent body of our Board, will take into account the relevant available facts and circumstances including, but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the risks, costs and benefits to us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the impact on a director's independence in the event that the related person is a director, immediate family member of a director or an entity with which a director is affiliated;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the availability of other sources for comparable services or products; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp;the terms available to or from, as the case may be, unrelated third parties or to or from employees generally.

The policy requires that, in determining whether to approve, ratify or reject a related person transaction, our audit committee, or other independent body of our Board, must consider, in light of known circumstances, whether the transaction is in, or is not inconsistent with, our best interests and those of our shareholders, as our audit committee, or other independent body of our Board, determines in the good faith exercise of its discretion.

**CERTAIN RELATED PARTY TRANSACTIONS** 

Except as described below, there have been no transactions since the beginning of our last fiscal year, to which we have been a participant in which the amount involved exceeded or will exceed $120,000, and in which any of our directors, executive officers or holders of more than 5% of our share capital, or any members of their immediate family, had or will have a direct or indirect material interest, other than compensation arrangements which are described under "Executive Compensation" and "Director Compensation."

**HOUSEHOLDING OF PROXY MATERIALS**

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more shareholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those shareholders. This process, which is commonly referred to as "householding," potentially means extra convenience for shareholders and cost savings for companies.

This year, a number of brokers with account holders who are Biohaven's shareholders will be "householding" our proxy materials. A single Notice of Internet Availability of Proxy Materials will be delivered to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in "householding" and would prefer to receive a separate Notice of Internet Availability of Proxy Materials, please notify your broker or Biohaven. Direct your written request to Biohaven Ltd., Attn: Corporate Secretary, Biohaven Ltd., c/o Biohaven Pharmaceuticals, Inc., 215 Church Street, New Haven, CT 06510 or by phone at (401) 274-9200 or email at Douglas.Gray@troutman.com. Shareholders who currently receive multiple copies of the Notice of Internet Availability of Proxy Materials at their addresses and would like to request "householding" of their communications should contact their brokers.
