Nature of the Business and Basis of Presentation

Biohaven Ltd. (“we,” “us," "our," "Biohaven" or the “Company”) was incorporated in Tortola, British Virgin Islands in May 2022. We are a global clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of life-changing therapies for people with debilitating neurological and neuropsychiatric diseases, including rare disorders. The Company is advancing a pipeline of therapies with target indications, including epilepsy, mood disorders, Obsessive-Compulsive Disorder (“OCD”), Spinal Muscular Atrophy (“SMA”) and pain disorders. Our neuroscience portfolio includes a broad pipeline of drug candidates modulating distinct nervous system targets, including Kv7 ion channels (“Kv7”), glutamate receptors, myostatin, and Transient Receptor Potential (“TRP”) channels.

Separation from Biohaven Pharmaceutical Holding Company Ltd.

On May 9, 2022, Biohaven Pharmaceutical Holding Company Ltd. (the "Former Parent"), Pfizer Inc. (“Pfizer”) and a wholly owned subsidiary of Pfizer (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), which provided for the acquisition by Pfizer of the Former Parent through the merger of Merger Sub with and into the Former Parent (the “Merger”). In connection with the Merger Agreement, the Former Parent and Biohaven Ltd. entered into a Separation and Distribution Agreement, dated as of May 9, 2022 (the “Distribution Agreement”). In connection with the Distribution Agreement, the Board of Directors of the Former Parent approved and directed the Former Parent’s management to effect the Spin-Off of the business, operations, and activities that are not the CGRP Business (as defined below), including the Kv7 ion channel activators, glutamate modulation, MPO inhibition and myostatin inhibition platforms, preclinical product candidates, and certain corporate infrastructure currently owned by the Former Parent.

To implement the Spin-Off, the Former Parent transferred the related license agreements, intellectual property and corporate infrastructure, including certain non-commercial employee agreements, share based awards and other corporate agreements (the "Business") to Biohaven Ltd., through a series of internal restructuring transactions. Descriptions of historical business activities in these Notes to Condensed Combined Financial Statements are presented as if these transfers had already occurred,

and the Former Parent’s activities related to such assets and liabilities had been performed by the Company.

On October 3, 2022, the Former Parent completed the distribution (the “Distribution”) to holders of its common shares of all of the outstanding common shares of Biohaven Ltd. and the spin-off of Biohaven from the Former Parent (the “Spin-Off”) described in Biohaven’s Information Statement (the “Information Statement”) attached as Exhibit 99.1 to Biohaven’s Registration Statement on Form 10, as amended (Reg. No. 001-41477), which was declared effective by the Securities and Exchange Commission ("SEC") on September 22, 2022 (the “Form 10”). Each holder of Former Parent common shares received one common share of Biohaven for every two Former Parent common shares held of record as of the close of business, New York City time, on September 26, 2022. In the Distribution, an aggregate of 35,832,557 Biohaven common shares were issued. As a result of the Distribution, Biohaven Ltd. became an independent, publicly traded company.

The Spin-Off generally resulted in (a) the Company directly or indirectly owning, assuming, or retaining certain assets and liabilities of the Former Parent and its subsidiaries related to the Former Parent’s pipeline assets and businesses and (b) the Former Parent directly or indirectly owning, assuming, or retaining all other assets and liabilities, including those associated with the Former Parent’s platform for the research, development, manufacture and commercialization of calcitonin gene-related receptor antagonists, including rimegepant, zavegepant and the Heptares Therapeutics Limited preclinical CGRP portfolio and related assets (the “CGRP Business”).

The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. Product candidates currently under development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval, prior to commercialization. These efforts may require additional capital, additional personnel and infrastructure, and further regulatory and other capabilities. Even if the Company’s product development efforts are successful,

it is uncertain when, if ever, the Company will realize significant revenue from product sales.

Upon formation and through September 30, 2022, Biohaven Ltd. had 100 common shares of no par value outstanding.

Basis of Presentation

The accompanying condensed combined financial statements present, on a historical basis, the combined assets, liabilities, expenses and cash flows directly attributable to the Business, which have been prepared from the Former Parent’s consolidated financial statements and accounting records, and are presented on a stand-alone basis as if the operations had been conducted independently from the Former Parent. Historically, separate financial statements have not been prepared for the Company and it had not operated as a standalone business from the Former Parent during the periods covered by the condensed combined financial statements.

The condensed combined financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).

The condensed combined financial statements of operations and comprehensive loss include all costs directly related to the Business, including costs for facilities, functions and services utilized by the Company. The condensed combined statements of operations and comprehensive loss also include allocations for various expenses related to the Former Parent’s corporate functions, including research and development, human resources, information technology, facilities, tax, shared services, accounting, finance and legal. These expenses were allocated on the basis of direct usage or benefit when specifically identifiable, with the remainder allocated on a proportional cost allocation method primarily based on employee labor hours or direct expenses. Management believes the assumptions underlying the condensed combined financial statements, including the expense methodology and resulting allocation, are reasonable for all periods presented. However, the allocations may not include all of the actual expenses that would have been incurred by the Company and may not reflect its combined results of operations, financial position and cash flows had it been a standalone company during the periods presented. It is not practicable to estimate actual costs that would have been incurred had the Company been a standalone company and operated as

an unaffiliated entity during the periods presented. Actual costs that might have been incurred had the Company been a standalone company would depend on a number of factors, including the chosen organizational structure, what corporate functions the Company might have performed directly or outsourced and strategic decisions the Company might have made in areas such as executive management, legal and other professional services, and certain corporate overhead functions.

The income tax amounts in the condensed combined financial statements have been calculated on a separate return method and are presented as if the Company’s operations were separate taxpayers in the respective jurisdiction. Therefore, tax expense, cash tax payments, and items of current and deferred taxes may not be reflective of the Company’s actual tax balances prior to or subsequent to the Distribution.

On October 3, 2022, the Company entered into several agreements with the Former Parent in connection with the Spin-Off, including a Transition Services Agreement, a United States Distribution Services Agreement and Outsourcing & Employee Transfer Agreements. For additional information regarding these agreements, see Note 10, Subsequent Events.

The Company expects to continue to incur certain costs to establish itself as a standalone public company, as well as ongoing additional costs associated with operating as an independent, publicly traded company.

The condensed combined balance sheets include assets and liabilities that have been determined to be specifically identifiable or otherwise attributable to the Company, including certain assets that were historically held at the corporate level in the Former Parent. All intracompany transactions within the Company have been eliminated. All intercompany transactions between the Company and the Former Parent are considered to be effectively settled in the condensed combined financial statements at the time the transactions are recorded. The total net effect of these intercompany transactions considered to be settled is reflected in the condensed combined statement of cash flows within financing activities and in the condensed combined balance sheets as “Net investment from Former Parent.” See Note 9, Related Party Transactions for additional information regarding related party transactions.

Our equity balance in these condensed combined financial statements represents the excess of total assets over liabilities. Net investment from Former Parent is primarily impacted by contributions from

Parent, which are the result of net funding provided by or distributed to Parent.

Cash on the condensed combined balance sheets represents cash balances from the standalone entities established to operate the Business and that were contributed to the Company in connection with the Spin-Off. As of September 30, 2022, the Company was a co-obligor, jointly and severally with the Former Parent on its third-party long-term debt obligations with Sixth Street Specialty Lending, Inc. The Former Parent’s third-party long-term debt and related interest expense are not reflected in the condensed combined financial statements because the Company had not agreed to pay a specified amount of the borrowings on the basis of its arrangement with the Former Parent, nor was the Company expected to pay any portion of the Former Parent’s third-party debt, and the borrowings are not specifically identifiable to the Company. On October 3, 2022, an affiliate of Pfizer, on behalf of the Former Parent, repaid in full all of the indebtedness and other obligations and liabilities owed by the Former Parent, including prepayment penalties. In connection with the termination and repayment in full of the indebtedness and other obligations and liabilities under the Sixth Street Financing Agreement, all related liens and security interests granted by or arising under the Sixth Street Financing Agreement were automatically released and discharged. See Note 7, Commitments and Contingencies for additional information regarding debt.

Going Concern

In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the condensed combined financial statements are issued.

Through November 9, 2022, the Company has funded its operations primarily with proceeds from Biohaven Pharmaceutical Holding Co. Ltd., its Former Parent, its recent public offering as discussed in Note 10, Subsequent Events, and the cash contribution received from the Former Parent at the Distribution as discussed below. The Company has incurred recurring losses since its inception and expects to continue to generate operating losses for the foreseeable future.

Pursuant to the Distribution Agreement, immediately prior to the Distribution, the Former Parent made a cash contribution to the Company which resulted in a cash balance of approximately $257,799 as

of October 3, 2022. Additionally, on October 25, 2022, the Company completed a public offering of its common shares which resulted in net proceeds to the Company of approximately $282,763. See Note 10, Subsequent Events, for further detail on the public offering. Accordingly, as of the date of issuance of these condensed combined financial statements, the Company expects its existing cash will be sufficient to fund operating expenses, financial commitments and other cash requirements for at least one year after the issuance date of these financial statements. The Company’s future viability will be dependent on its ability to raise additional capital to finance its operations.

To execute its business plans, the Company will require funding to support its continuing operations and pursue its growth strategy. Until such time as the Company can generate significant revenue from product sales or royalties, if ever, it expects to finance its operations through the sale of public or private equity, debt financings or other capital sources, including collaborations with other companies or other strategic transactions. The Company may not be able to obtain financing on acceptable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of the Company’s shareholders. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate some or all of its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.
