1.   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. Biohaven is a biopharmaceutical company focused on the discovery, development and commercialization of life-changing treatments in key therapeutic areas, including immunology, neuroscience, and oncology. The Company is advancing its innovative portfolio of therapeutics, leveraging its proven drug development experience and multiple, proprietary drug development platforms. Biohaven's extensive clinical and preclinical programs include Kv7 ion channel modulation for epilepsy and mood disorders; extracellular protein degradation for immunological diseases; Transient Receptor Potential Melastatin 3 ("TRPM3") antagonism for migraine and neuropathic pain; Tyrosine Kinase 2/Janus Kinase 1 ("TYK2/JAK1") inhibition for neuroinflammatory disorders; glutamate modulation for obsessive compulsive disorder ("OCD") and spinocerebellar ataxia ("SCA"); myostatin inhibition for neuromuscular and metabolic diseases, including spinal muscular atrophy ("SMA") and obesity; and antibody recruiting bispecific molecules ("ARMs") and antibody drug conjugates ("ADCs") for cancer.
The Company is subject to risks and uncertainties common to 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.
Separation from Biohaven Pharmaceutical Holding Company Ltd.
On October 3, 2022, Biohaven Pharmaceutical Holding Company Ltd. (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 Ltd.
from the Former Parent (the “Spin-Off”) described in Biohaven’s Information Statement attached as Exhibit 99.1 to Biohaven’s Registration Statement on Form 10, as amended (Reg. No. 001-41477). Collectively, we refer to the Distribution and Spin-Off throughout this Quarterly Report on Form 10-Q as the "Separation." As a result of the Separation, Biohaven 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. Where we describe historical business activities in this report, we do so as if the Former Parent’s activities related to such assets and liabilities had been performed by the Company.
Basis of Presentation
The accompanying condensed consolidated 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 SEC. The accompanying condensed consolidated financial statements include the accounts of Biohaven Ltd. and our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
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 consolidated financial statements are issued.
Through August 9, 2024, the Company has funded its operations primarily with funding from the Former Parent, proceeds from the sale of its common shares, and the cash contribution received from the Former Parent at the Separation. The Company has incurred recurring losses since its inception and expects to continue to generate operating losses for the foreseeable future.
As of the date of issuance of these condensed consolidated financial statements, the Company expects its existing cash, cash equivalents, and marketable securities will be sufficient to fund operating and financial commitments, and other cash requirements for at least one year after the issuance date of these financial statements.

1.   Nature of the Business and Basis of Presentation (Continued)
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.
2.   Summary of Significant Accounting Policies
Our significant accounting policies are described in Note 2, "Summary of Significant Accounting Policies" to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Form 10-K"). Updates to our accounting policies are discussed below in this Note 2.
Unaudited Interim Condensed Consolidated Financial Information
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information. The accompanying unaudited condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. The accompanying year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of June 30, 2024, the results of its operations for the three and six months ended June 30, 2024 and 2023, and its cash flows for the six months ended June 30, 2024 and 2023. The results for the three and six months ended June 30, 2024 are not necessarily indicative of results to be expected for
the year ending December 31, 2024, any other interim periods or any future year or period.  The financial information included herein should be read in conjunction with the financial statements and notes in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.
Reclassifications
Certain items in the prior period’s condensed consolidated financial statements have been reclassified to conform to the current year presentation.
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual for research and development expenses and valuation of forward contract and derivative liabilities. In addition, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.
Restricted Cash
Restricted cash included in other current assets in the condensed consolidated balance sheets consists primarily of employee contributions to the Company's employee share purchase plan held for future purchases of the Company's outstanding shares.
Restricted cash included in other non-current assets in the condensed consolidated balance sheets represents collateral held by banks for a letter of credit ("LOC") issued in connection with the leased office space in Yardley, Pennsylvania and LOCs issued in connection with the leased office and lab spaces in Cambridge, Massachusetts and Pittsburgh, Pennsylvania. See Note 11, ‘‘Commitments and Contingencies’’ for additional information on the real estate leases.

The following represents a reconciliation of cash and cash equivalents in the condensed consolidated balance sheets to total cash, cash equivalents and restricted cash as of June 30, 2024 and June 30, 2023, respectively, in the condensed consolidated statements of cash flows:

Total cash, cash equivalents and restricted cash at the end of the period in the condensed consolidated statement of cash flows$242,318 $201,950 
Forward Contracts and Derivative Liabilities
The Company evaluates certain of its financial and business development transactions to determine the accounting classification of equity linked instruments issued in those transactions. The Company first assesses whether a freestanding equity linked instrument meets liability classification in accordance with ASC 480-10 Distinguishing Liabilities from Equity and ASC 815-40 Derivatives and Hedging - Contracts in Entity's Own Equity. Under ASC 480-10 an instrument is considered liability classified if the instrument is mandatorily redeemable, obligate the issuer to settle an instrument or the underlying shares by paying cash or other assets, or must or may require settlement by issuing variable number of shares.
If an instrument does not meet liability classification under ASC 480-10, the Company assesses the requirements under ASC 815-40, which states that contracts that require or may require net cash settlement are liabilities recorded at fair value. If the instrument does not require liability classification under ASC 815-40, in order to conclude equity classification, the Company assesses whether the instrument is indexed to its common stock and whether the instrument is classified as equity under ASC 815-40 or other applicable GAAP.
Equity linked instruments that are accounted for in accordance with ASC 815-40 are reported as liabilities on the condensed consolidated balance sheets at fair
value. Any change in fair value, as determined at each measurement period, is recorded as a component of other income (expense), net on the condensed consolidated statements of operations and comprehensive loss. Changes in fair value are reported on the condensed consolidated statements of cash flows as change in fair value of forward contract and derivative liabilities.
The Company accounted for certain consideration agreed to in connection with the Amendment, dated as of May 1, 2024 (the "Knopp Amendment"), to the Membership Interest Purchase Agreement, dated as of February 24, 2022 (the "Purchase Agreement") entered into with Knopp Biosciences, LLC ("Knopp") as derivative liabilities under ASC 815 (see Notes 4, "Fair Value of Financial Assets and Liabilities" and 10, "License, Acquisitions and Other Agreements").
Warrants
The Company evaluates warrants issued as either equity instruments, liabilities or derivative liabilities in accordance with ASC Topic 480, Distinguishing Liabilities from Equity ("ASC 480") and/or ASC Topic 815, Derivatives and Hedging ("ASC 815"), depending on the specific terms of the warrant agreement.
The Company assessed the warrants issued to Knopp in May 2024 (the "Knopp Warrants") and concluded that they met the criteria for equity classification under ASC 480 and ASC 815. Accordingly, the Knopp Warrants were recorded within additional paid-in capital on the condensed consolidated balance sheet at the time of issuance and are not subject to remeasurement. See Note 6, Shareholders' Equity for further detail on the Knopp Warrants.
Fair Value Measurements
Certain assets and liabilities of the Company are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value

hierarchy, of which the first two are considered observable and the last is considered unobservable:
•Level 1—Quoted prices in active markets for identical assets or liabilities.
•Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.
•Level 3—Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.
The carrying values of other current assets, accounts payable, and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities.
The Company has accounted for certain consideration agreed to in connection with the Knopp Amendment as forward contract liabilities, which are recorded on the condensed consolidated balance sheets at fair value. Any changes in fair value, as determined each measurement period, are recorded as a component of other income (expense), net on the condensed consolidated statements of operations and comprehensive loss. The fair value of the forward contract liabilities is determined based on significant inputs not observable in the market, and therefore represents a Level 3 measurement within the fair value hierarchy. The valuations are based on a Monte Carlo simulation of the Company's share price, which requires judgement and assumption on the volatility of
Biohaven's share price, discounted to present value using a risk-free rate plus Biohaven specific credit risk since payable in a variable number of shares. (see Notes 4, "Fair Value of Financial Assets and Liabilities" and 10, "License, Acquisitions and Other Agreements").
Recently Issued Accounting Pronouncements
In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting—Improvements to Reportable Segment Disclosures, which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in ASU No. 2023-07 apply to public entities, including those with a single reportable segment, and are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact ASU No. 2023-07 will have on its consolidated financial statements
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also includes certain other amendments to improve the effectiveness of income tax disclosures. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024, with early adoption permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the impact ASU No. 2023-09 will have on its consolidated financial statements.

4.   Fair Value of Financial Assets and Liabilities
The preparation of the Company’s condensed consolidated financial statements in accordance with GAAP requires certain assets and liabilities to be reflected at their fair value and others to be reflected on another basis, such as an adjusted historical cost basis. In this note, the Company provides details on the fair value of financial assets and liabilities and how it determines those fair values.
Financial Instruments Measured at Fair Value on the Condensed Consolidated Balance Sheets
Certain assets of the Company are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:
•Level 1 — Quoted prices in active markets for identical assets or liabilities.
•Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.
•Level 3 — Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

The Company had no financial liabilities measured at fair value on a recurring basis on the condensed consolidated balance sheets at December 31, 2023.
There were no securities transferred into or out of Level 3 during the three and six months ended June 30, 2024 or 2023.
The following is a description, including valuation methodology, of the financial assets measured at fair value on a recurring basis:
Cash Equivalents
Cash equivalents consisted of cash invested in short-term money market funds and debt securities with an original maturity of 90 days or less at the date of purchase. The carrying value of cash equivalents approximates fair value as maturities are less than three months. When quoted prices are available in an active market, cash equivalents are classified in Level 1 of the fair value hierarchy. Fair values of cash equivalent instruments that do not trade on a regular basis in active markets are classified as Level 2.

4.   Fair Value of Financial Assets and Liabilities (Continued)
Marketable Securities and Other Non-Current Assets
Quoted prices for identical assets in active markets are considered Level 1 and consist of on-the-run U.S. Treasuries and money market funds. The fair values of the Company’s Level 2 debt securities are obtained from quoted market prices of debt securities with similar characteristics, quoted prices from identical assets in inactive markets, or discounted cash flows to estimate fair value.
Forward Contract and Derivative Liabilities
In connection with the Knopp Amendment, Knopp has the option to request a one-time cash true-up payment from the Company in December 2024, as defined in the agreement (the "2024 Additional Consideration True-up"). The Company also agreed to issue to Knopp additional common shares of the Company with an approximate value of $75,000 within 60 days of the first anniversary of execution of the Knopp Amendment (the “2025 Additional Consideration”). In addition, Knopp has the option to request a one-time cash true-up payment from the Company in December 2025, as defined in the agreement (the "2025 Additional Consideration True-up"). See Note 10, "License, Acquisitions and Other Agreements," for further details.
The following table provides a roll forward of the fair value of the Company's forward contract and derivative liabilities related to the Knopp Amendment for which fair value is determined by Level 3 inputs for the three months ended June 30, 2024:
Carrying Value
Fair value at May 1, 2024
$93,290 
Change in fair value of derivative in other income (expense), net
110 
Fair value at June 30, 2024
$93,400 
The fair value of the forward contract and derivative liabilities recognized in connection with the Knopp Amendment were determined based on significant inputs not observable in the market, and therefore represents a Level 3 measurement within the fair value hierarchy. The valuation is based on a Monte Carlo simulation of Biohaven's share price, which requires judgement and assumption on the volatility of Biohaven's share price, discounted to present value using a risk-free rate plus Biohaven specific credit risk since payable in a variable number of shares for the 2025 Additional Consideration or potentially cash for the 2024 Additional Consideration True-up and 2025 Additional Consideration True-up. A summary of the unobservable inputs (Level 3 inputs) used in measuring the Company’s forward contract and derivative liabilities related to the Knopp Amendment as of June 30, 2024 and May 1, 2024 are as follows, presented on a weighted-average basis:
As of June 30, 2024
As of May 1, 2024
Time to payment and potential payment (years)
0.911.08
Volatility (annual)
70.0 %80.0 %
Discount rate
15.6 %14.8 %
Our expectations of the volatility of Biohaven's share price at the reporting date could be materially different than our actual future volatility, and if so, would mean the estimated fair value could be significantly higher or lower than the fair value determined. The Company expects the fair value of the forward contract to be approximately $75,000 on the first anniversary of the Knopp Amendment. An increase in the derivative liabilities related to the 2024 Additional Consideration True-up and 2025 Additional Consideration True-up between the reporting date and settlement date of the derivatives would have a material adverse effect on the Company's financial performance.

8. Non-Cash Share-Based Compensation
Non-Cash Share-based Compensation Expense
The Company measures non-cash share-based compensation at the grant date based on the fair value of the award and recognizes non-cash shared-based compensation as expense over the requisite service period of the award (generally three years) using the straight-line method. Non-cash share-based compensation expense, consisting of expense for share options, restricted share units ("RSUs"), performance share options, and the Employee Share Purchase Plan ("ESPP"), was classified in the condensed consolidated statements of operations and comprehensive loss as follows:

Three Months Ended June 30,Six Months Ended June 30,

Total non-cash share-based compensation expense$12,232 $4,695 $47,109 $8,460 
Share Options
All share option grants are awarded at fair value on the date of grant. The fair value of share options is estimated using the Black-Scholes option pricing model. Stock options generally expire 10 years after the grant date.
The aggregate intrinsic value of share options is calculated as the difference between the exercise price of the share options and the fair value of the Company's common shares for those share options that had exercise prices lower than the fair value of the Company's common shares at June 30, 2024.
As of June 30, 2024, total unrecognized compensation cost related to the unvested share options was $90,206, which is expected to be recognized over a weighted average period of 2.33 years, which does not consider the impact of a change in control. The weighted average grant date fair value per share of share options granted under the Company's share option plan during the six months ended June 30, 2024 and 2023 was $30.76 and $10.16, respectively. The Company expects

Restricted Share Units
The Company’s RSUs are considered nonvested share awards and require no payment from the employee. For each RSU, employees receive one common share at the end of the vesting period. The employee can elect to receive the one common share net of taxes or pay for taxes separately and receive the entire share. Compensation cost is recorded based on the market price of the Company’s common shares on the grant date and is recognized on a straight-line basis over the requisite service period.
As of June 30, 2024, there was $9,405 of total unrecognized compensation cost related to Company RSUs that are expected to vest. These costs are expected to be recognized over a weighted-average period of 2.53 years, which does not consider the impact of a change in control. The total fair value of RSUs vested during the three and six months ended June 30, 2024 was $3,770.

The Company's potential dilutive securities include share options which have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common shareholders of the Company is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common shareholders for the periods indicated because including them would have had an anti-dilutive effect:

10.  License, Acquisitions and Other Agreements
The Company has entered into various licensing, developmental and acquisition agreements which provide the Company with rights to certain know-how, technology and patent rights. The agreements generally include upfront fees, milestone payments upon achievement of certain developmental, regulatory and commercial and sales milestones, as well as sales-
based royalties, with percentages that vary by agreement.
License and Other Agreements
As of June 30, 2024, the Company has potential future developmental, regulatory and commercial milestone payments under its license and other agreements of up to approximately $140,650, $641,975, and $2,150,450, respectively. See below for a detailed discussion of these agreements. The Company has not recorded these potential contingent consideration payments as liabilities in the accompanying condensed consolidated balance sheet as none of the future events which would trigger a milestone payment were considered probable of occurring at June 30, 2024.
Yale Agreements
In September 2013, the Company entered into an exclusive license agreement (the "Yale Agreement") with Yale University to obtain a license to certain patent rights for the commercial development, manufacture, distribution, use and sale of products and processes resulting from the development of those patent rights, related to the use of riluzole in treating various neurological conditions, such as general anxiety disorder, post-traumatic stress disorder and depression.
The Yale Agreement was amended and restated in May 2019. As of June 30, 2024, under the amended Yale Agreement, the Company has remaining contingent regulatory approval milestone payments of up to $2,000 and annual royalty payments of a low single-digit percentage based on net sales of riluzole-based products from the licensed patents or from products based on troriluzole. Under the amended and restated agreement, the royalty rates are reduced as compared to the original agreement. In addition, under the amended and restated agreement, the Company may develop products based on riluzole or troriluzole. The amended and restated agreement retains a minimum annual royalty of up to $1,000 per year, beginning after the first sale of product under the agreement. If the Company grants any sublicense rights under the Yale Agreement, it must pay Yale University a low single-digit percentage of sublicense income that it receives.
For the three and six months ended June 30, 2024 and 2023, the Company did not record any material milestone or royalty payments under the Yale Agreement.
In January 2021, the Company entered into a worldwide, exclusive license agreement with Yale

University for the development and commercialization of a novel Molecular Degrader of Extracellular Protein ("MoDE") platform (the "Yale MoDE Agreement"). The platform pertains to the clearance of disease-causing protein and other biomolecules by targeting them for lysosomal degradation using multi-functional molecules. The Yale MoDE Agreement includes an obligation to pay a minimum annual royalty of up to $1,000 per year, and low single digit royalties on the net sales of licensed products. If the Company grants any sublicense rights under the Yale MoDE Agreement, it must pay Yale University a low single-digit percentage of sublicense income that it receives. As of June 30, 2024, under the Yale MoDE Agreement, the Company has remaining contingent development and commercial milestone payments of up to $650 and $2,950, respectively. The Yale MoDE Agreement terminates on the later of twenty years from the effective date, twenty years from the filing date of the first investigational new drug application for a licensed product or the last to expire of a licensed patent.
The Company did not record any material milestone or royalty payments under the Yale MoDE Agreement for the three months ended June 30, 2024. For the six months ended June 30, 2024, the Company recorded research and development expense of $150 related to the achievement of a developmental milestone under the Yale MoDE Agreement. For the three and six months ended June 30, 2023, the Company did not record any material milestone or royalty payments under the Yale MoDE Agreement.
ALS Biopharma Agreement
In August 2015, the Company entered into an agreement (the "ALS Biopharma Agreement") with ALS Biopharma and Fox Chase Chemical Diversity Center Inc.

Acquisitions
Kv7 Platform Acquisition
In April 2022, the Company closed the acquisition from Knopp of Channel Biosciences, LLC (“Channel”), a wholly owned subsidiary of Knopp owning the assets of Knopp’s Kv7 channel targeting platform (the “Kv7 Platform Acquisition”), pursuant to the Purchase Agreement, dated February 24, 2022.
Under the Purchase Agreement, the Company agreed to make success-based payments based on developmental and regulatory milestones through approvals in the United States, Europe, the Middle East and Asia ("EMEA") and Japan for the lead asset, BHV-7000 (formerly known as KB-3061), developmental and regulatory milestones for the Kv7 pipeline development in other indications and additional country approvals, and commercial sales-based milestones of BHV-7000. Additionally, the Company agreed to make scaled royalty payments in cash for BHV-7000 and the pipeline programs, with percentages starting at high single digits and peaking at low teens for BHV-7000 and starting at mid-single digits and peaking at low tens digits for the pipeline programs.
In May 2024, the Company entered into the Knopp Amendment under which the parties thereto agreed to replace the scaled high single digit to low teens royalty payment obligations with a flat royalty payment in the mid-single digits for BHV-7000 and the pipeline programs. The parties also agreed to reduce the success-based payments payable under the Purchase Agreement. The Company retains the ability to pay these contingent milestone payments in cash or in the Company's common shares at Biohaven's election, subject to the same increases if the Company elects to pay in the Company's common shares. As of June 30, 2024, under the Purchase Agreement, as amended, the Company had remaining success-based payments comprised of (i) to up to $185,000 based on regulatory approvals in the United States and EMEA for BHV-7000 and (ii) up to an additional $60,000 based on regulatory approval in the United States for the other Kv7 pipeline programs.
In consideration of the revisions to the success-based payment and royalty payment obligations, the Company agreed to issue to Knopp 1,872,874 Company common shares, valued at approximately $75,000, through a private placement within 60 days of the date of execution of the Knopp Amendment (the “2024 Additional Consideration”) and additional Company common shares with an approximate value of $75,000 within 60 days of the first anniversary of execution of the

Knopp Amendment (the “2025 Additional Consideration”). The Company has also given Knopp the option to request a one-time cash true-up payment from the Company in December 2024 in the event that Knopp continues to hold the Company's common shares representing the 2024 Additional Consideration and the value of such shares has declined (the "2024 Knopp True-Up"), and a one-time cash true-up payment from the Company in December 2025 in the event that Knopp continues to hold the Company's common shares representing the 2025 Additional Consideration and the value of such shares has declined (the "2025 Knopp True-Up"), in each case, subject to certain conditions.
The Company concluded that the agreement to issue the 2024 Additional Consideration at a future date represented a fixed forward contract under ASC 815 and classified the commitment as a forward contract liability on its condensed consolidated balance sheet on the execution date of the Knopp Amendment. The Company initially measured the forward contract associated with the 2024 Additional Consideration at a fair value of $75,220, which was recorded as R&D expense during the three months ended June 30, 2024 in its condensed consolidated statements of operations and comprehensive loss. In May 2024, the Company issued the 2024 Additional Consideration at an approximate value of $65,981 and recognized a $9,239 gain upon settlement of the forward contract in other income (expense), net in its condensed consolidated statement of operations and comprehensive loss during the three months ended June 30, 2024. The gain on settlement of the 2024 Additional Consideration is due to the decline in fair value of the 2024 Additional Consideration from the execution date to the issuance date due to a decline in Biohaven's share price. Refer to Note 4, "Fair Value of Financial Assets and Liabilities" and Note 6, "Shareholders' Equity" for further discussion.
The 2024 Additional Consideration True-up represents a net cash settled written put option measured at fair value on a recurring basis. The Company has concluded that the 2024 Additional Consideration True-up represents a net cash settled written put option on the Company’s shares and is a freestanding derivative liability under ASC 815. Accordingly, the Company classified the 2024 Additional Consideration True-up as a current derivative liability on its condensed consolidated balance sheet. The Company initially recorded the 2024 Additional Consideration True-up at a fair value of $15,540, which was recorded as R&D expense during the three months ended June 30, 2024 in its condensed consolidated statements of operations and comprehensive loss. The Company subsequently remeasures the fair value of the derivative
liability and recognizes any gains or losses through other income (expense), net in its condensed consolidated statement of operations and comprehensive loss. The Company recognized expense of $590 for the three months ended June 30, 2024, related to the 2024 Additional Consideration True-up. Refer to Note 4, "Fair Value of Financial Assets and Liabilities" for further discussion.
The Company has concluded that the agreement to issue the 2025 Additional Consideration at a future date represents a forward contract settleable in a variable number of shares under ASC 480, and classified the commitment as a current forward contract liability on its condensed consolidated balance sheet. The Company initially measured the 2025 Additional Consideration at a fair value of $63,940, which was recorded as R&D expense during the three months ended June 30, 2024 in its condensed consolidated statements of operations and comprehensive loss. The Company subsequently remeasures the fair value of the forward contract liability and recognizes any gains or losses through other income (expense), net in its condensed consolidated statement of operations and comprehensive loss. The Company recognized expense of $1,150 for the three months ended June 30, 2024, related to the 2025 Additional Consideration. Refer to Note 4, "Fair Value of Financial Assets and Liabilities" for further discussion.
The Company has concluded that the 2025 Additional Consideration True-up represents a net cash settled written put option on the Company’s shares and is a freestanding derivative liability under ASC 815. Accordingly, the Company classified the 2025 Additional Consideration True-up as a non-current derivative liability on its condensed consolidated balance sheet. The Company initially recorded the 2025 Additional Consideration True-up at a fair value of $13,810, which was recorded as R&D expense during the three months ended June 30, 2024. The Company subsequently remeasures the fair value of the derivative liability and recognizes any gains or losses through other income (expense), net in its condensed consolidated statement of operations and comprehensive loss. The Company recognized a gain of $1,630 for the three months ended June 30, 2024, related to the 2025 Additional Consideration True-up. Refer to Note 4, "Fair Value of Financial Assets and Liabilities" for further discussion.
As further consideration for the revisions to the success-based payment and royalty payment obligations in the Knopp Amendment, the Company issued to Knopp a warrant (the “Warrant”) to purchase 294,195 Company common shares at a purchase price per share of $67.98,

subject to certain specified development milestones and the Company achieving a specified market capitalization. Refer to Note 6, "Shareholders' Equity" for further discussion.
The Company has not recorded any of the remaining contingent consideration payments to Knopp as a liability in the accompanying condensed consolidated balance sheet as none of the future events which would trigger a milestone payment were considered probable of occurring at June 30, 2024.
Pyramid Acquisition
In January 2024, the Company acquired Pyramid Biosciences, Inc. (“Pyramid”), pursuant to an Agreement and Plan of Merger, dated January 7, 2024 ("the Pyramid Agreement"). In consideration for the Pyramid acquisition, Biohaven made an upfront payment of 255,794 Company common shares, valued at approximately $10,894.
The Company accounted for this purchase as an asset acquisition as substantially all of the fair value of the gross assets acquired was concentrated in a single identifiable asset, IPR&D. The IPR&D asset has no alternative future use and relates primarily to BHV-1510. There was no material value assigned to any other assets or liabilities acquired in the acquisition. As such, the upfront payment discussed above was recorded as a charge to R&D expense in the accompanying condensed consolidated statements of operations and comprehensive loss during the three months ended March 31, 2024.
As of June 30, 2024, under the Pyramid Agreement, the Company has remaining success-based payments comprised of (i) up to $5,000 based on developmental and regulatory milestones for the lead asset, BHV-1510 (formerly known as PBI-410), (ii) up to an additional $30,000 based on developmental and regulatory milestones for a second asset (formerly known as PBI-200) and (iii) up to $40,000 for commercial sales-based milestones of BHV-1510. Contingent developmental and regulatory milestone payments may be paid in cash or Biohaven common shares at the election of Biohaven and commercial sales-based milestones are to be made in cash.
The Company has not recorded any of the remaining contingent consideration payments as a liability in the accompanying condensed consolidated balance sheet as none of the future events which would trigger a milestone payment were considered probable of occurring at June 30, 2024.
During the first quarter of 2024, the Company recorded $5,689 of R&D expense in the condensed consolidated statement of operations and comprehensive loss for a developmental milestone which became due under the Pyramid Agreement, to be paid in 98,129 common shares of the Company. See Note 6, "Shareholders' Equity" for discussion of common shares issued to as part of the Pyramid Agreement.

Clinical-Stage Milestones
Our clinical-stage milestones include the following:Milestone88.jpg

Glutamate Modulation Platform
The most advanced product candidate from our glutamate receptor antagonist platform is troriluzole (previously referred to as trigriluzole and BHV-4157), which is currently in two Phase 3 trials in OCD and, for which we submitted a new drug application (“NDA”) in Spinocerebellar Ataxia Type 3 (“SCA3”) to the U.S. FDA and marketing authorisation application ("MAA") to the European Medicines Agency ("EMA"). Troriluzole is also being evaluated by the Global Coalition for Adaptive Research ("GCAR") as part of Glioblastoma Adaptive Global Innovative Learning Environment - NCT03970447 ("GBM AGILE"), a revolutionary patient-centered, adaptive platform trial for registration that tests multiple therapies for patients with newly-diagnosed and recurrent glioblastoma ("GBM"). Other product candidates include BHV-5500, which is an antagonist of the glutamate N-methyl-D-aspartate (“NMDA”) receptor and its oral prodrug BHV-5000.
Troriluzole
Spinocerebellar Ataxia
SCAs are a group of ultra-rare, dominantly inherited neurodegenerative disorders predominantly characterized by atrophy of the cerebellum, brainstem, and spinal cord. The disease course of SCA is one of relentless progression over years and inevitably leads to clinical deterioration of motor function, gait imbalance with frequent falling, severe speech impairment, swallowing difficulties, and premature death. SCAs are thought to be pathogenetically related but disease course and brain region involvement are known to vary
between the different genotypes. SCA3, also known as Machado-Joseph disease, is the most common genotype, with a prevalence of up to 6,000 patients in North America and up to 4,600 in the European Union (“EU”) and Japan, and accounts for approximately 30% to 50% of SCAs worldwide. Currently, there are no approved symptomatic or neuroprotective treatments for SCA.
In May 2022, the Company announced top-line results from the Phase 3 clinical trial (Study BHV4157-206) evaluating the efficacy and safety of its investigational therapy, troriluzole, in patients with SCA. The primary endpoint, change from baseline to week 48 on the modified functional Scale for the Assessment and Rating of Ataxia ("f-SARA"), did not reach statistical significance in the overall SCA population as there was less than expected disease progression in the placebo arm over the course of the study. Preliminary post hoc analysis of efficacy measures by genotype suggested a treatment effect in patients with the SCA3 genotype (p=0.045, LSM difference from placebo). A risk reduction in falls was also observed in the SCA3 population, as well as across all SCA genotypes. Troriluzole was well tolerated with an adverse event profile similar to placebo.
Based on the findings of further analyses performed and the debilitating nature of SCA, in May 2023 we announced that we submitted a New Drug Application ("NDA") to the FDA for troriluzole for the treatment of SCA3. In July 2023, the FDA informed us that it would not review the recently submitted NDA application for troriluzole given that the study's primary endpoint was not met and thus, would not permit a
28
substantive review. In followup to the regulatory decision on the NDA application, we held followup meetings with the FDA regarding the SCA data.
We continue to have constructive dialogue with the FDA regarding our SCA development program and potential future data analyses to address regulatory concerns in the previously issued refuse-to-file decision on the NDA application for SCA3. As a result of regulatory interactions, Biohaven designed a new protocol to assess the effectiveness of troriluzole after 3 years of treatment in SCA. This new protocol, BHV4157-206-RWE (NCT06529146), uses real world evidence ("RWE") of effectiveness using real-world data ("RWD") sources to examine the treatment effects of troriluzole in SCA after up to 3 years of therapy compared to external control subjects collected from the US SCA Natural History cohort ("CRC-SCA"). The data analysis will incorporate new patient data that was previously unavailable and not analyzed in the prior FDA submission. The primary outcome measure for BHV4157-206-RWE is the change from baseline on the f-SARA. The protocol was designed to be consistent with FDA’s Guidance for Industry, "Considerations for the Use of Real-World Data and Real-World Evidence to Support Regulatory Decision Making for Drug and Biological Products." The protocol and SAP were submitted and reviewed by FDA prior to database lock of newly available 3-year data. Topline data from this protocol is expected in the second half of 2024 and, if positive, could form the basis of a new drug application to the FDA. We will provide further updates on the SCA development program as warranted by any continued positive progress from the outcome of future regulatory interactions on this topic.
In October, 2023, the European Medicines Agency ("EMA") informed us that our Marketing Authorization Application ("MAA") for troriluzole (Dazluma) in the treatment of SCA has been validated and is now under review by EMA's Committee for Medicinal Products for Human Use ("CHMP").
We remain committed to working closely with the health authorities to bring troriluzole to people with SCA, given no therapy is currently approved for this ultra-rare genetic disorder.
Obsessive Compulsive Disorder
We commenced a Phase 2/3 double-blind, randomized, controlled trial to assess the efficacy of troriluzole in adults with OCD in December 2017. The Phase 2/3 study results were announced in June 2020. Troriluzole 200 mg administered once daily as adjunctive therapy in OCD patients with inadequate response to standard of care treatment showed consistent numerical improvement over placebo on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at all study timepoints (weeks 4 to 12) but did not meet the primary outcome measure at week 12. Troriluzole treated subjects (n = 111) had a mean Y-BOCS improvement of -3.4 points from baseline versus -2.9 for placebo-treated (n = 115) subjects [difference -0.5 and p-value = 0.451] at week 4, -5.1 points (n = 96) versus -3.6 for placebo-treated (n = 108) subjects [difference
-1.5 and p-value = 0.041] at week 8, and -5.9 points (n = 99) versus -4.9 for placebo-treated (n = 102) subjects [difference -1.0 and p-value = 0.220] at week 12. Troriluzole’s safety profile was generally consistent with past clinical trial experience with its active metabolite, riluzole. Treatment emergent adverse events (“TEAE”s) were mostly reported to be mild in intensity. TEAEs that occurred in at least 5% of patients in the troriluzole group, and more frequently in the troriluzole group than in the placebo group, were headache, dizziness, fatigue, somnolence, nausea and nasopharyngitis.
Given the strong signal in the Phase 2/3 proof of concept study and after receiving feedback from the FDA in an End of Phase 2 meeting, in December 2020 we initiated enrollment in a Phase 3 program. The Phase 3 program will have an estimated total enrollment of up to 700 participants in each trial with a primary endpoint of change from baseline on the Y-BOCS total score at week 4, 8 and 10. The two Phase 3 randomized, double-blind, placebo-controlled trials that make-up our Phase 3 program for OCD are currently ongoing.
In January 2024, we announced plans to conduct a pre-planned interim analysis ("IA") to evaluate efficacy in the first of our two Phase 3 studies in OCD. The IA was planned to be conducted by an independent Data Monitoring Committee after approximately 70% of subjects in the primary analysis population reached the primary endpoint. The Data Monitoring Committee convened in the second quarter of 2024 to review the IA and informed the Company that the study may continue. As such, we continue enrolling patients in the first Phase 3 study in OCD and expect that this study will be fully enrolled in the first quarter of 2025. We expect to report topline data from the first Phase 3 study in OCD in the first half of 2025.
There is a similarly designed pre-planned IA for the second Phase 3 study in OCD, with topline results from this IA anticipated in the second half of 2024.
Glioblastoma
In December 2021, GCAR selected troriluzole for evaluation in GBM AGILE. GBM AGILE is a revolutionary patient-centered, adaptive platform trial for registration that tests multiple therapies for patients with newly-diagnosed and recurrent GBM, the most fatal form of brain cancer. Troriluzole will be evaluated in all patient subgroups of the trial which include newly-diagnosed methylated MGMT, newly-diagnosed unmethylated MGMT, and recurrent GBM. Troriluzole was selected for inclusion in GBM AGILE based on compelling evidence showing deregulation of glutamate in GBM. The therapeutic potential of troriluzole in GBM and other oncology indications is supported by several recent clinical and translational research studies conducted with troriluzole and its active moiety.
In July 2022, the Company and GCAR announced that enrollment has commenced in GBM AGILE for the
29
evaluation of troriluzole. Enrollment in the study is ongoing.
Myostatin Platform
Taldefgrobep Alfa (BHV-2000)
In February 2022, we announced a worldwide license agreement with BMS for the development and commercialization rights to taldefgrobep alfa (also known as BMS-986089 and now referred to as BHV-2000), a novel, Phase 3-ready anti-myostatin adnectin. Myostatin is a natural protein that limits skeletal muscle growth, an important process in healthy muscular development that can lead to improvements of lean mass and loss of adipose tissue. In patients with neuromuscular diseases, active myostatin can critically limit the growth needed to achieve developmental and functional milestones. Myostatin inhibition is a promising therapeutic strategy for enhancing muscle mass and strength in a range of pediatric and adult neuromuscular conditions. In addition, preclinical and early clinical data suggest that blocking myostatin and downstream signaling through its receptors on skeletal muscle may produce physical and metabolic changes that are important to individuals living with overweight and obesity, including reducing body fat and improving insulin sensitivity while increasing lean muscle mass. Taldefgrobep’s novel mode of action and unique impact on body composition suggest it could be used as monotherapy or in combination with other anti-obesity medications.
Spinal Muscular Atrophy
In July 2022, we commenced enrollment in a Phase 3 clinical trial of BHV-2000 assessing the efficacy and safety of taldefgrobep alfa in Spinal Muscular Atrophy ("SMA"). SMA is a rare, progressively debilitating motor neuron disease in which development
and growth of muscle mass are compromised, resulting in progressive weakness and muscle atrophy, reduced motor function, impaired quality of life and often death. The Phase 3 placebo-controlled, double-blind trial is designed to evaluate the efficacy and safety of taldefgrobep as an adjunctive therapy for participants who are already taking a stable dose of nusinersen or risdiplam or have a history of treatment with onasemnogene abeparvovec-xioi (Zolgensma), compared to placebo. The study is neither restricted nor limited to patients based on ambulatory status or classification of SMA and is designed to randomize approximately 180 patients in this randomized, double-blind, placebo-controlled global trial. Baseline characteristics of the population enrolled in the ongoing Phase 3 study in SMA were reported and confirmed to be well matched to the target clinical population. The primary endpoint of the study, the 32 Item Motor Function Measurement, is a reliable and validated endpoint for measuring clinically meaningful benefit in SMA. We expect to report topline data from our Phase 3 study in the second half of 2024.
In February 2023, we received Fast Track designation from the FDA for taldefgrobep alfa for the treatment of SMA. In December 2022, we received orphan drug designation from the FDA for taldefgrobep in the treatment of SMA. In July 2023, we received orphan drug designation from the European Commission for taldefgrobep alfa in the treatment of SMA.
In April 2024, we announced that the FDA granted "rare pediatric disease" designation for taldefgrobep alfa. The designation provides for the potential for taldefgrobep to receive a priority review voucher (“PRV”) if ultimately approved for the indication of SMA.
Metabolic Disorders
Obesity is a disease of excess and/or abnormal deposits of adipose tissue and a current global public health crisis. By 2030, it is expected that nearly one billion people will be living with obesity, including 50% of the adult and 25% of the adolescent US population. The primary driver of obesity-related morbidity and mortality is metabolically active visceral adipose tissue and associated deposits of adipose tissue in and around organs such as the heart, liver, kidneys, and muscle.
Preclinical and clinical data have demonstrated the potential for anti-myostatin therapies to produce physical and metabolic changes that are highly relevant to individuals living with overweight and obesity, including reducing total body fat and visceral adiposity, and improving insulin sensitivity and bone mineral density, while increasing lean muscle mass.
In October 2023, we announced preclinical data demonstrating the ability of taldefgrobep alfa to significantly reduce fat mass while increasing lean mass in an obese mouse model. In a mouse model of diet-induced obesity, untreated mice exhibited an increase in fat mass of 31%, while the mice treated with taldefgrobep alfa demonstrated increases in lean mass of 25% from baseline (p≤.0.001) and lost 11% of their baseline fat (p≤.0.001) compared to vehicle (placebo) treated mice. Insulin and leptin levels were consistently lower in mice treated with taldefgrobep alfa compared to the untreated mice. There was no difference in food intake over time across the taldefgrobep alfa and untreated mice, counter to what has been observed with incretin mimetics (e.g., semaglutide) which are consistently associated with a reduction in energy intake.
30
In May 2024, we announced preclinical data from a diet induced obesity mouse model, which showed treatment with taldefgrobep alfa together with a glucagon-like peptide-1 ("GLP-1") agonist produced greater reductions in body weight and fat mass, and a larger increase in lean muscle mass, compared to treatment with GLP-1 alone (see figure below).
TALFA.jpg
We plan to initiate a Phase 2 clinical trial of taldefgrobep in the management of metabolic disease in the second half of 2024. The study will evaluate the ability of taldefgrobep to maintain lean mass muscle as an adjunctive to standard of care GLP-1 therapy in adults living with overweight and obesity. We are evaluating and have not yet finalized potential clinical trial designs, including size and primary and secondary endpoints.

Ion Channel Platform
Kv7
BHV-7000
In April 2022, we closed the acquisition from Knopp Biosciences LLC (“Knopp”) of Channel Biosciences, LLC, a wholly owned subsidiary of Knopp owning the assets of Knopp’s Kv7 channel targeting platform, pursuant to a Membership Interest Purchase Agreement, dated February 24, 2022 (the "Purchase Agreement"). The acquisition of the Kv7 channel targeting platform added the latest advances in ion-channel modulation to our growing neuroscience portfolio. BHV-7000 (formerly known as KB-3061), the lead asset from the Kv7 platform is an activator of Kv7.2/Kv7.3, a key ion channel involved in neuronal signaling and in regulating the hyperexcitable state in epilepsy.
In the second quarter of 2022, our Clinical Trial Application for BHV-7000 was approved by Health Canada, and we subsequently began Phase 1 clinical development. First-in-human single ascending dose ("SAD") and multiple ascending dose ("MAD") studies have now been completed. BHV-7000 was well-tolerated at all dose levels in both studies with no SAEs and no dose-limiting toxicities.
In 2023, we initiated a Phase 1 open-label electroencephalogram ("EEG") study designed to evaluate the effects of BHV-7000 on changes from baseline in EEG spectral power after administration of single doses of BHV-7000 (10, 25, or 50 mg) to healthy adult volunteers. BHV-7000 was well-tolerated at all doses studied and EEG data showed dose-dependent increases in brain spectral power, with minimal power increase in the delta frequency band and the highest spectral power increases in the alpha, beta, and gamma frequency bands. The minimal impact of BHV-7000 on slower frequencies (i.e., delta) is consistent with the low incidence of central nervous system ("CNS") adverse events, in particular somnolence, seen in the BHV-7000 Phase 1 SAD/MAD studies, and the study results confirm the CNS activity of BHV-7000 at projected therapeutic concentrations.
Based on the results from the EEG study and the safety profile in SAD/MAD trials, along with PK data from a new once-daily extended-release (“ER”) formulation, Biohaven plans on exploring three oral dose levels of once-daily BHV-7000 (25 mg, 50 mg, and 75 mg) in the Phase 2/3 clinical trials in epilepsy and mood disorders. This dosing approach with a Kv7 activator will allow for assessment of distinct target concentrations over a wide range, above and below EC50 drug concentrations efficacious in nonclinical models, not previously feasible with drugs in this class.
31
Epilepsy
Epilepsy is the initial disease we are targeting with activators from our Kv7 platform. Epilepsy affects approximately 3.5 million Americans, or more than 1.2% of adults and 0.6% of children in the U.S., and more than 50 million patients worldwide, according to the World Health Organization (“WHO”). It is the fourth most common neurological disorder, and many patients struggle to achieve freedom from seizures, with more than one third of patients requiring two or more medications to manage their epilepsy. While the use of anti-seizure medications is often accompanied by dose-limiting side effects, our clinical candidate BHV-7000 is specifically designed to target subtypes of Kv7 potassium channels without engagement of GABAA receptors. The lack of GABAA-R activity potentially gives BHV-7000 a wide therapeutic window which we expect to result in an improved side effect profile, limiting the somnolence and fatigue often seen in patients receiving anti-seizure medications. By adding BHV-7000 to our pipeline, we aim to bring this potassium channel modulator as a potential solution to patients with epilepsy who remain uncontrolled on their current regimens.
In January 2024, we completed our End-of-Phase 2 meeting with the FDA to advance to Phase 3 trials and announced that more than 110 global clinical sites have been selected in the first of two focal epilepsy trials. Enrollment in our Phase 2/3 program commenced in the first quarter of 2024. The two pivotal studies evaluating the efficacy of BHV-7000 in refractory focal epilepsy are planned as randomized, double-blind, placebo-controlled, 8- and 12-week trials with a primary endpoint of change from baseline in 28-day average seizure frequency in adults with focal epilepsy. One of the focal epilepsy studies will evaluate 25 mg and 50 mg doses of BHV-7000 and the second study will evaluate 50 mg and 75 mg doses of BHV-7000 (see figure below).
focaltrialdesign.jpg
In addition to the focal epilepsy program, we initiated a Phase 2/3 study of BHV-7000 in idiopathic generalized epilepsy ("IGE") in the second quarter of 2024. The pivotal study evaluating the efficacy of BHV-7000 with IGE is planned
32
as a randomized, double-blind, placebo-controlled 24-week time-to-event trial with a primary endpoint of time to second generalized seizure in adults and adolescents with IGE (see figure below).
IGEdesignQ2.jpg
Mood Disorders
Approximately 1 in 5 adults in the US are living with neuropsychiatric illnesses that are, in turn, associated with inadequate treatment, poor quality of life, disability, and considerable direct and indirect costs. There is significant unmet need for novel and effective therapeutic options that are not limited by long latency periods to clinical effects, low response rates, and significant risks and side effects. Increasing evidence from animal models and clinical trials now suggests that Kv7.2/7.3 targeting drugs offer the potential to treat a spectrum of these neuropsychiatric diseases including, but not limited to, mood disorders, such as major depressive disorder ("MDD") and bipolar disorder.
Major Depressive Disorder
We initiated a Phase 2 clinical trial with BHV-7000 for the treatment of MDD in the second quarter of 2024. The study is a 6 week, randomized, double-blind, placebo-controlled trial in approximately 300 subjects, with a primary endpoint of measurement on the Montgomery-Asberg Depression Rating Scale ("MADRS"). See figure below for trial design.
MDD.jpg
33
Bipolar disorder
We also initiated a Phase 2/3 clinical trial with BHV-7000 for the treatment of bipolar disorder in the second quarter of 2024. The study is a 3 week, randomized, double-blind, placebo-controlled trial in approximately 256 subjects, with a primary endpoint of measurement on the Young Mania Rating Scale ("YMRS"). See figure below for trial design.
bipolar.jpg
KCNQ2 Developmental Epileptic Encephalopathy
We are currently exploring BHV-7000 as a potential treatment for KCNQ2 developmental epileptic encephalopathy ("KCNQ2-DEE"), a rare pediatric epileptic encephalopathy first described in 2012 resulting from dominant-negative mutations in the KCNQ2 gene. BHV-7000 has been granted Rare Pediatric Disease Designation by the United States Food and Drug Administration (the “FDA”) for the treatment of KCNQ2-DEE.
Neuropathic Pain
We are currently evaluating the activity of BHV-7000 and other compounds from our proprietary series of selective Kv7.2/7.3 activators in multiple preclinical models of neuropathic pain.
Migraine
We are currently exploring BHV-7000 as a potential treatment for migraine. Kv7.2/7.3 openers have shown significant activity in cortical spreading depression models of migraine.
TRPM3 Ion Channel Antagonists
In January 2022, we entered into an Exclusive License and Research Collaboration Agreement with Katholieke Universiteit Leuven ("KU Leuven") to develop and commercialize TRPM3 antagonists to address the growing proportion of people worldwide living with chronic pain disorders (the "KU Leuven Agreement"). The TRPM3 antagonist platform was discovered at the Centre for Drug Design and Discovery and the Laboratory of Ion Channel Research at KU Leuven. Under the KU Leuven Agreement, we receive exclusive global rights to develop, manufacture and commercialize KU Leuven's portfolio of small-molecule TRPM3 antagonists. The portfolio includes the lead candidate, henceforth known as BHV-2100.
BHV-2100
BHV-2100 is an orally-bioavailable small molecule antagonist of TRPM3. TRPM3 is expressed in the relevant human tissue types for pain and migraine, and both preclinical models and human genetics implicate TRPM3 in pain and migraine.
In May 2024, we reported positive pharmacokinetic and safety data from the completed Phase 1 study with BHV-2100. The results demonstrated rapid absorption with therapeutic concentrations achieved by 20 minutes. The favorable tolerability profile at single doses up to 500 mg exceeds the anticipated therapeutic dose and is well above the EC90 concentration. Based on these findings, we plan to advance BHV-2100 into a Phase 2 study in the acute treatment of migraine and a proof-of-concept study in pain in the second half of 2024.
Migraine
We expect to initiate a BHV-2100 Phase 2 study in acute migraine in the second half of 2024. We are evaluating and have not yet finalized clinical trial design, including trial size, and primary and secondary endpoints for the anticipated clinical trial.
Neuropathic Pain
BHV-2100 is also being developed as a potential non-opioid treatment for neuropathic pain. We are evaluating the ability of BHV-2100 to reduce pain behaviors across several preclinical models of neuropathic pain, including chemotherapy induced
34
neuropathy, diabetic neuropathy, and nerve injury. The Company expects to conduct a proof of concept study for neuropathic pain in the second half of 2024.
Additional research on TRPM3-mediated disorders
Under the KU Leuven Agreement, Biohaven is supporting further basic and translational research at KU Leuven on the role of TRPM3 in pain and other disorders. In addition to BHV-2100, we are optimizing other lead compounds for TRPM3-mediated disorders of the peripheral and central nervous systems.
Inflammation and Immunology Platform
TYK2/JAK1
Agreement with Hangzhou Highlightll Pharmaceutical Co. Ltd.
In March 2023, we entered into an exclusive, worldwide (excluding People’s Republic of China and its territories and possessions) license agreement with Hangzhou Highlightll Pharmaceutical Co. Ltd. ("Highlightll"), pursuant to which we obtained the right to research, develop, manufacture and commercialize Highlightll’s brain penetrant dual TYK2/JAK1 inhibitor program (the "Highlightll Agreement").
BHV-8000
Dysregulation of the immune system has been implicated in several neurodegenerative and neuroinflammatory disorders including Parkinson's disease, multiple sclerosis, Alzheimer's disease, amyotrophic lateral sclerosis and autoimmune encephalitis. Over-active immune cells and microglia driving chronic neuroinflammation result in release of cytokines with activation of leukocytes that is thought to contribute to neuronal injury, death, gliosis, and demyelination. The TYK2 and JAK1 signal transduction pathways mediate highly complementary immune and inflammatory signaling events. Targeted, small-molecule therapies that inhibit TYK2 or JAK kinases have separately demonstrated robust efficacy in autoimmune, dermatologic and gastrointestinal disorders. TYK2 is a validated immune target as evidenced by a recent peripheral program that gained FDA approval, and there are multiple additional peripheral non-CNS programs in clinical development. Brain penetrant inhibitors of TYK2/JAK1 have the potential to bring this validated immune target to brain disorders.
There are currently no brain penetrant, selective, dual TYK2/JAK1 inhibitors approved for brain disorders. In May 2023, we began dosing with BHV-8000 (previously TLL-041), in a Phase 1 study in normal healthy volunteers. In May 2024, we reported positive results from the Phase 1 single and multiple ascending dose study with BHV-8000 in healthy subjects, including evidence of target engagement along with a safe and well tolerated profile. The Phase 1 study also confirmed cerebrospinal fluid ("CSF") exposures of BHV-8000 and
evidence of biomarker target engagement within the CNS. We also announced the successful completion of two FDA meetings with favorable feedback enabling registrational programs for Parkinson's disease and for the prevention of ARIA, a novel indication.
We anticipate beginning Phase 2/3 clinical trials with BHV-8000 in the second half of 2024 targeting neuroinflammatory conditions, potentially including Amyloid-Related Imaging Abnormalities ("ARIA") in Alzheimer’s disease, Alzheimer's disease, Parkinson's disease and multiple sclerosis. We are evaluating and have not yet finalized potential clinical trial designs, including size and primary and secondary endpoints.
MoDE Degraders
Bispecific Molecular Degraders of Extracellular Proteins
Molecular Degraders of Extracellular Proteins (“MoDEs”) are bispecific molecules that target pathologic circulating proteins and direct them to the liver for degradation by the endolysosomal pathway. Our MoDE platform is being explored for use in a wide range of therapeutic areas, including indications in immune-mediated diseases, cancer and other diseases. We are planning for MoDEs to be administered as intravenous or subcutaneous formulations. We expect to initiate a total of 4 Investigational New Drug Applications or the foreign equivalent ("IND") for the degrader program in 2024.
BHV-1300
BHV-1300 is an IgG degrader which we are initially developing for the treatment of rheumatoid arthritis ("RA"). RA is a chronic autoimmune disease estimated to affect 1 to 2% of the global population. RA primarily affects the joints, causing pain, swelling, stiffness, and loss of function.
We evaluated the effect of single and multiple doses of BHV-1300 in cynomolgus monkeys. In September 2023, we reported data from confirmatory studies that showed a 75-80% reduction of IgG levels two days after a single dose and over 90% of IgG lowering after three doses.
1300repeateddosing.jpg
35
Maximal lowering across FcRn inhibitors is 60-80% within approximately 7 to 21 days after initiation of single or multiple doses, respectively, in cynomolgus. In contrast, a single dose of BHV-1300 lowers IgG by approximately 75 to 80% after approximately 2 days, and after three rapid doses to greater than 90% lowering. The length of significant exposure to BHV-1300 is approximately one day within the dosage interval compared to continuous exposure required of the FcRn inhibitors. Mechanism related liabilities of FcRn inhibitors seen in animals and man, including hypoalbuminemia and hypercholesterolemia, are not expected and do not occur with BHV-1300 in cynomolgus. See figures below comparing the speed and depth of lowering to FcRn inhibitors.
1300 comparison.jpg
In January 2024, we reported preclinical pharmacodynamic single dose data with BHV-1300 which demonstrated the Biohaven IgG degrader technology allows for co-administration with Fc-containing biologics. The PK of Humira® was unaltered after being dosed 12 hours after BHV-1300 administration (see figure below).
humira.jpg
* Adapted from BLA 761154, IND 116471, Study no. r-fkb327-01
The Phase 1 study examining BHV-1300 was initiated in the first quarter of 2024 and remains ongoing. In May 2024, we reported preliminary results from our Phase 1 study of BHV-1300. These results in healthy subjects reported that BHV-1300 rapidly and selectively lowers IgG in a dose-dependent manner in
the first 4 cohorts completed to date (see figure below). Preliminary IgG lowering data is consistent with modeling, with dose- and time-dependent IgG lowering observed even in initial low-dose cohorts. Some subjects experienced IgG reductions as low as 50 to 70% of baseline. BHV-1300 demonstrated reduction of IgG without significantly impacting LFTs, albumin, LDL cholesterol or other serum labs. BHV-1300 has been safe and well tolerated to date, with no serious or severe adverse events. Most AEs were mild, deemed unrelated to study drug and resolved spontaneously. As expected from the selectivity of the molecule for IgG, when compared to placebo, there were no meaningful reductions in average IgA, IgM or IgE levels during the week after dosing. No adverse trends have been observed in vital signs or ECGs. Modeling suggests additional cohorts in the Phase 1 study will achieve greater than 70% lowering of IgG utilizing doses compatible with subcutaneous administration.
36
1300graphQ2.jpg
The Phase 1 study has also compared intravenous and subcutaneous administration of BHV-1300. Subcutaneous administration of BHV-1300 demonstrated an average of approximately 44% higher than expected exposure compared to the dose-equivalent intravenous formulation without injection site reactions. This new human data confirms the feasibility
of the Company's plan for convenient dosing of BHV-1300 with a patient self-administered subcutaneous auto-injector. The Company expects to provide further updates on the BHV-1300 development program by the end of 2024.
BHV-1310
BHV-1310 is a next generation bispecific IgG degrader with the same specificity as BHV-1300 for IgG1, IgG2 and IgG4 which is initially being developed for the treatment of rare disorders including conditions like generalized myasthenia gravis ("gMG") and potentially other acute or chronic conditions, or chronic conditions with acute exacerbations or flares.
MG is a neuromuscular disorder that is estimated to affect approximately 36,000 to 60,000 people in the United States. Patients with gMG develop antibodies that attack critical signaling receptor proteins at the junction between nerve and muscle cells, inhibiting communication between nerves and muscle and resulting in weakness of the skeletal muscles.
In January 2024, we demonstrated optimization of degrader technology with BHV-1310 which allows for deeper reductions in IgG after single dose (see figure below). The deep and rapid reductions observed suggest that BHV-1310 could have potential application in acute settings. We expect to initiate Phase 1 studies of BHV-1310 in the second half of 2024. We are evaluating and have not yet finalized potential clinical trial designs, including size and primary and secondary endpoints.
1310.jpg
BHV-1400
BHV-1400 is a selective MoDE which is being developed to target Gd-IgA1 for the treatment of IgA Nephropathy. Specific removal of pathogenic Gd-IgA1 and associated circulating immune complexes with preservation of normal IgA potentially permits disease remission without incurring an infection risk. We shared preliminary data demonstrating the chimeric antibody-ASGPR ligand conjugate specifically mediated endocytosis of Gd-IgA1, as opposed to normal IgA1 and IgA2, in an endocytosis assay with ASGPR-expressing cell lines, and that MoDE degraders successfully internalize and degrade these immune-complexes. We
expect to initiate Phase 1 studies of BHV-1400 in the second half of 2024. We are evaluating and have not yet finalized potential clinical trial designs, including size and primary and secondary endpoints.
BHV-1600
BHV-1600 is a selective MoDE designed to remove circulating agonistic antibodies of all isotypes and subclasses directed against myocardial beta-1 adrenergic receptor ("β-1 AR") through hepatic ASGPR binding and hepatocellular degradation. This molecule was created using a peptide that mimics the antigenic epitope common to most patients with autoantibodies directed to β-1 AR. This peptide mimics the native
37
sequence such that circulating antibodies are efficiently trapped and subsequently removed by hepatic endocytosis through the ASGPR receptor.
We are developing BHV-1600 for the treatment of dilated cardiomyopathy. Dilated cardiomyopathy is a condition where the cardiac muscle contracts less effectively, the chambers of the heart are enlarged and thinning of cardiac walls results. This can lead to cardiac valvular incompetency, arrhythmias, thrombosis, and heart failure. We expect to initiate Phase 1 studies of BHV-1600 in the second half of 2024. We are evaluating and have not yet finalized potential clinical trial designs, including size and primary and secondary endpoints.
Additional Degraders
We are currently developing additional MoDE degraders which will advance to INDs in 2025. These include potential treatments for Type 1 diabetes with our degrader targeting anti-insulin and anti-proinsulin autoantibodies, kidney disease with our degrader targeting phospholipase A2 receptor ("PLA2R") antibodies for idiopathic membranous nephropathy, an IgG4 specific degrader to target IgG4-mediated rare diseases, and gene therapy administration optimization with our degrader to target neutralizing antibodies to Adeno-Associated Virus Serotype 9 ("AAV9").
Oncology Platform
CD-38
BHV-1100
In the fourth quarter of 2021, we initiated a Phase 1a/1b trial in multiple myeloma patients using its antibody recruiting molecule BHV-1100 in combination with autologous cytokine induced memory-like natural killer cells and immune globulin to target and kill multiple myeloma cells expressing the cell surface protein CD38. BHV-1100 is the lead clinical asset from Biohaven’s Antibody Recruiting Molecule ("ARM™") Platform developed from a strategic alliance with PeptiDream Inc. ("PeptiDream") (TYO: 4587). This open-label single center Phase 1a/1b study will assess the safety and tolerability as well as exploratory efficacy endpoints in newly diagnosed multiple myeloma patients who have tested positive for minimal residual disease (“MRD+”) in first or second remission prior to autologous stem cell transplant (“ASCT”). We plan to enroll 30 newly diagnosed multiple myeloma patients. The primary outcome measures are dose limiting toxicities following combination product administration (time frame: 100 days post-combination product administration) and incidence and severity of side effects related to the combination product (time frame: 90 to 100 days post-combination product administration).
Antibody Drug Conjugates
BHV-1510
In January 2024, we acquired BHV-1510 through our acquisition of Pyramid Biosciences, Inc. ("Pyramid").
BHV-1510 is a next-generation Trophoblast Cell Surface Antigen 2 ("TROP-2") directed ADC employing an optimized next-generation construct with novel linker-payload and enzymatic, site-specific conjugation, targeting TROP2-expressing carcinomas. Carcinoma refers to a malignant neoplasm of epithelial origin. Carcinomas account for 80 to 90 percent of all cancer cases and several examples have been successfully treated with ADCs. Abundant TROP-2 expression has been described for many carcinoma subtypes.
In preclinical TROP-2 expressing tumor models, BHV-1510 has shown improved antitumor activity versus other TROP-2 directed ADCs, in addition to improved plasma stability, more potent in vitro cytotoxicity, superior bystander effect, and greater immunogenic cell death with the novel TopoIx payload. Improved and differentiated safety has been seen in cynomolgus monkey GLP toxicology studies, suggesting a wide therapeutic index. BHV-1510 has similar favorable characteristics to our proprietary MATE conjugation technology, which should allow highly stable site-specific conjugation, resulting in a favorable PK, toxicity and manufacturability profile.
The IND for BHV-1510 was approved by the FDA in January 2024. The First-in Human, Phase 1/2 trial evaluating BHV-1510 in patients with advanced solid tumors commenced in the second quarter of 2024. This trial consists of two parts; Phase 1 dose escalation and Phase 2 dose expansion, in patients with advanced incurable cancer that have progressed on or are intolerant to standard therapy. The primary objective of Phase 1 is safety, to identify a recommended dose for expansion ("RDE") or maximum tolerated dose. Phase 1 dose escalation will be implemented based on a Bayesian optimal interval design, with the lowest dose initiated as a single patient cohort. Patients are expected to be dosed in escalating cohorts, with dosing regimens administered intravenously every three weeks. The Phase 2 dose expansion part of the study will consist of non-randomized efficacy finding expansion cohorts, defined by specific tumor types that will be treated at the RDE to estimate the anti-tumor activity of BHV-1510. Up to approximately 170 subjects are planned to be evaluated.
Preclinically, BHV-1510 has shown enhanced cellular cytotoxicity, bystander killing, and immunogenic cell death resulting in improved efficacy as monotherapy, and synergistic efficacy in combination with anti-PD-1 therapy. In IND-enabling studies, BHV-1510 also showed a broader therapeutic margin relative to more advanced Trop-2 ADCs, including a lack of lung toxicity, that may translate to an improved clinical efficacy and safety profile. In May 2024, we announced that we entered into a clinical supply agreement with Regeneron Pharmaceuticals, Inc. ("Regeneron") under which we will sponsor and fund the planned combination clinical trial and Regeneron will provide Libtayo®. Libtayo® is a fully-human monoclonal antibody targeting the immune checkpoint receptor programmed cell death protein-1 ("PD-1").

BHV-1500
BHV-1500 is a next-generation CD30-directed ADC employing a Biohaven proprietary site-specific conjugation (MATE reagent), targeting CD30-expressing tumors such as Hodgkin's and other lymphoma and the MMAE payload. Hodgkin's disease and other CD30-expressing lymphoma are characterized by the uncontrolled growth of malignant lymphocytes or lymphoblasts. Adcetris has demonstrated effectiveness in the treatment of Hodgkin's Lymphoma.
In preclinical CD30 expressing murine tumor models, BHV-1500 has shown improved antitumor activity versus Adcetris (brentuximab vedotin), and substantially improved safety, plasma stability and pharmacokinetics in monkeys. We expect to submit an IND for BHV-1500 in 2025.
Recent Developments
Amendment to Knopp Purchase Agreement
In May 2024, we entered into an amendment to the Purchase Agreement with Knopp (the “Knopp Amendment”). Under the Knopp Amendment, the parties thereto agreed to replace the scaled high single digit to low teens royalty payment obligations with a flat royalty payment in the mid-single digits for BHV-7000 and the pipeline programs. The parties also agreed to reduce the success-based payments payable under the Purchase Agreement by removing all commercial sales-based milestones, which were up to $562.5 million, and reducing the developmental and regulatory milestones, which were up to $575 million, to up to $210 million based on regulatory approvals in the United States and EMEA for BHV-7000 ($25 million of which has already been paid) and up to an additional $60 million based on regulatory approval in the United States for the other Kv7 pipeline programs. We retain the ability to pay these contingent milestone payments in cash or in Biohaven Shares at our election, subject to the same increases if we elect to pay in Biohaven Shares.
In consideration of the revisions to the success-based payment and royalty payment obligations, we agreed to issue to Knopp 1,872,874 Biohaven Shares, valued at approximately $75 million, through a private placement within 60 days of the date of execution of the Knopp Amendment (the “2024 Additional Consideration”) and additional Biohaven Shares with an approximate value of $75 million within 60 days of the first anniversary of execution of the Knopp Amendment (the “2025 Additional Consideration”). We have also given Knopp the option to request a one-time cash true-up payment from us in December 2024 in the event that Knopp continues to hold the Biohaven Shares representing the 2024 Additional Consideration and the value of such shares has declined, and a one-time cash true-up payment from us in December 2025 in the event that Knopp continues to hold the Biohaven Shares representing the 2025 Additional Consideration and the value of such shares has declined, in each case, subject
to certain conditions. In May 2024, we issued the 2024 Additional Consideration at an approximate value of $66.0 million.
As further consideration for the revisions to the success-based payment and royalty payment obligations in the Knopp Amendment, we issued to Knopp a warrant (the “Warrant”) to purchase 294,195 Biohaven Shares at a purchase price per share of $67.98, subject to certain specified development milestones and the Company achieving a specified market capitalization.
For further discussion of the Knopp Amendment, refer to Note 4, "Fair Value of Financial Assets and Liabilities", Note 6, "Shareholders' Equity, " and Note 10, " License, Acquisitions and Other Agreements" to the accompanying condensed consolidated financial statements included in this Form 10-Q.
Components of Our Results of Operations
Revenue
To date, we have not generated any revenue from product sales and we do not expect to generate any revenue from the sale of products in the near future. If our development efforts for our product candidates are successful and result in regulatory approval or additional license agreements with third parties, then we may generate revenue in the future from product sales.
Operating Expenses
Research and Development Expenses
Research and development ("R&D") expenses consist primarily of costs incurred in connection with the development of our product candidates. We expense research and development costs as incurred. These expenses include:
•expenses incurred under agreements with contract research organizations ("CROs") or contract manufacturing organizations (“CMOs”), as well as investigative sites and consultants that conduct our clinical trials, preclinical studies and other scientific development services;
•manufacturing scale-up expenses and the cost of acquiring and manufacturing preclinical and clinical trial materials and commercial materials, including manufacturing validation batches;
•employee-related expenses, including salaries, benefits, travel and non-cash share-based compensation expense for employees engaged in research and development functions;
•costs related to compliance with regulatory requirements;
•development milestone payments incurred prior to regulatory approval of the product candidate;
39
•rent and operating expenses incurred for leased lab facilities and equipment; and
•payments made in cash, equity securities or other forms of consideration under third-party licensing or other agreements prior to regulatory approval of the product candidate.
We recognize external development costs based on an evaluation of the progress to completion of specific tasks using estimates from our clinical personnel and information provided to us by our service providers.
Our external direct research and development expenses are tracked on a program-by-program basis for our product candidates and consist primarily of external costs, such as fees paid to outside consultants, CROs, CMOs, and central laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. Our direct research and development expenses by program also include fees and certain development milestones incurred under license agreements. We do not allocate employee costs, or other indirect costs, to specific programs because these costs are deployed across multiple programs and, as such, are not separately classified. We use internal resources primarily to oversee the research and development as well as for managing our preclinical development, process development, manufacturing and clinical development activities.
Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect that our research and development expenses will remain significant over the next several years as we increase personnel costs, conduct late-stage clinical trials, and prepare regulatory filings for our product candidates. We also expect to incur additional expenses related to milestones payable to third parties with whom we have entered into license agreements to acquire the rights to our product candidates.
The successful development and commercialization of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the preclinical and clinical development of any of our product candidates or when, if ever, material net cash inflows may commence from any of our product candidates. This uncertainty is due to the numerous risks and uncertainties associated with product development and commercialization, including the uncertainty of:
•the scope, progress, outcome and costs of our preclinical development activities, clinical trials and other research and development activities;
•establishment of an appropriate safety profile with IND-enabling studies;
•successful patient enrollment in, and the initiation and completion of, clinical trials;
•the timing, receipt and terms of any marketing approvals from applicable regulatory authorities;
•establishment of commercial manufacturing capabilities or making arrangements with third-party manufacturers;
•development and timely delivery of commercial-grade drug formulations that can be used in our clinical trials and for commercial launch;
•acquisition, maintenance, defense and enforcement of patent claims and other intellectual property rights;
•significant and changing government regulation;
•initiation of commercial sales of our product candidates, if and when approved, whether alone or in collaboration with others; and
•maintenance of a continued acceptable safety profile of the product candidates following approval.
General and Administrative Expenses
General and administrative ("G&A") expenses consist primarily of personnel costs, including salaries, benefits and travel expenses for our executive, finance, business, corporate development and other administrative functions; and non-cash share-based compensation expense. General and administrative expenses also include facilities and other related expenses, including rent, depreciation, maintenance of facilities, insurance and supplies; and for public relations, audit, tax and legal services, including legal expenses to pursue patent protection of our intellectual property.
We anticipate that our general and administrative expenses, including payroll and related expenses, will remain significant in the future as we continue to support our research and development activities and prepare for potential commercialization of our product candidates, if successfully developed and approved. We also anticipate increased expenses associated with general operations, including costs related to accounting and legal services, director and officer insurance premiums, facilities and other corporate infrastructure, office-related costs, such as information technology costs, and certain costs to establish ourself as a standalone public company, as well as ongoing additional costs associated with operating as an independent, publicly traded company.
Other Income, Net
Other income, net primarily consists of changes in the fair value of our forward contract and derivative liabilities and net investment income.
40
The fair value of the forward contracts and derivative liabilities recognized in connection with the Knopp Amendment are determined using a Monte Carlo simulation of the Company's stock price over the respective duration and terms of each instrument being valued. Refer to Note 4, "Fair Value of Financial Assets and Liabilities" to the accompanying condensed consolidated financial statements included in this Form 10-Q for detail on valuation inputs and methodology. The fair value of these liabilities are recorded on the condensed consolidated balance sheets with changes in fair value recorded in other income, net in the condensed consolidated statements of operations and comprehensive loss.
Net investment income is comprised of interest income and net accretion and amortization on investments in addition to realized gains and losses. Refer to Note 3, "Marketable Securities," to the accompanying condensed consolidated financial statements included in this Form 10-Q for further detail on our investments.
Provision for Income Taxes
The income tax expense in the condensed consolidated financial statements was calculated on a separate return method and presented as if the Company’s operations were separate taxpayers in the respective jurisdictions up to and including the Separation. Cash tax payments, income taxes receivable and deferred taxes, net of valuation allowance, are reflective of our actual tax balances prior and subsequent to the Separation.
As a company incorporated in the BVI, we are principally subject to taxation in the BVI. Under the
current laws of the BVI, the Company and all dividends, interest, rents, royalties, compensation and other amounts paid by the Company to persons who are not resident in the BVI and any capital gains realized with respect to any shares, debt obligations, or other securities of the Company by persons who are not resident in the BVI are exempt from all provisions of the Income Tax Ordinance in the BVI.
We have historically outsourced all of the research and clinical development for our programs under a master services agreement with Biohaven Pharmaceuticals, Inc. ("BPI"). As a result of providing services under this agreement, BPI was profitable during the three and six months ended June 30, 2024 and 2023. A similar arrangement is also in place for our subsidiary, Biohaven Biosciences Ireland Limited ("BBIL") also operates under a similar arrangement. Both Companies are subject to taxation in the US and Ireland, respectively. As such, in each reporting period, the tax provision includes the effects of the results of operations of BPI and BBIL.
At June 30, 2024 and December 31, 2023, we continued to maintain a full valuation allowance against our net deferred tax assets, comprised primarily of research and development tax credit carryforwards and net operating loss carryforwards, based on management’s assessment that it is more likely than not that the deferred tax assets will not be realized.
Our income tax provisions primarily represent Federal and state taxes related to the profitable operations of our subsidiaries in the United States and Ireland.

R&D expenses, including non-cash share-based compensation costs, were $314.8 million for the three months ended June 30, 2024, compared to $79.5 million for the three months ended June 30, 2023. The increase of $235.3 million was due, in part, to a one-time non-cash expense of $171.9 million paid to Knopp for a milestone and royalty buyback related to the BHV-7000 and broader Kv7 platform that was recognized during the three months ended June 30, 2024 (the buyback reduced our potential future milestone payments by $867.5 million, and replaced the scaled high single digit to low teens royalty payment obligations with a flat royalty payment in the mid-single digits for the Kv7 programs). The increase in R&D expenses was also due to advancing our 6 clinical platforms including 5 Phase 3 starts for BHV-7000, follow-on Kv7 assets, preclinical research programs, and increases in direct program spend for additional and advancing multiple clinical development programs. See further discussion of the Knopp Amendment included in Note 10, "License, Acquisitions and Other Agreements" to the condensed consolidated financial statements included in this Form 10-Q. The increase in expense was also related to advancing our 6 clinical platforms including 5 phase 3 starts for BHV-7000, follow-on Kv7 assets, preclinical research programs, and increases in direct program spend for additional and advancing multiple clinical development programs during the three months ended June 30, 2024, as compared to the same period in the prior year.
Non-cash share-based compensation expense was $7.1 million for the three months ended June 30, 2024, an increase of $4.6 million as compared to the same period in 2023. Non-cash share-based compensation expense was higher in 2024 primarily due to our annual equity incentive awards granted in the fourth quarter of 2023 and the first quarter of 2024.
General and Administrative Expenses
General and administrative expenses were $19.0 million for the three months ended June 30, 2024, compared to $14.5 million for the three months ended June 30, 2023. The increase of $4.4 million was primarily due to increased non-cash share-based compensation expense. Non-cash share-based compensation expense was $5.2 million for the three months ended June 30, 2024, an increase of $2.9 million as compared to the same period in 2023. Non-cash share-based compensation expense was higher in 2024 primarily due to our annual equity incentive awards granted in the fourth quarter of 2023 and the first quarter of 2024.
Other Income, Net
Other income, net was a net income of $14.2 million for the three months ended June 30, 2024, compared to $5.8 million for the three months ended June 30, 2023. The increase was primarily due to a $9.2 million gain recorded upon settlement of our forward contract liability for the 2024 Additional Consideration issued under the Knopp Amendment, and increased investment income. This was partially offset by a decrease in other
42
income recognized during the three months ended June 30, 2024 as compared to the same period in 2023 related to the Transition Services Agreement entered into with the Former Parent. See Note 4, "Fair Value of Financial Assets and Liabilities" to the accompanying condensed consolidated financial statements included in this Form 10-Q for discussion of the forward contract and derivative liabilities recorded in connection with the Knopp Amendment.
Provision for Income Taxes
We recorded an income tax provision of $0.2 million for the three months ended June 30, 2024, compared to
a provision for income taxes of $2.2 million for the three months ended June 30, 2023. The decrease in income tax expense for the three months ended June 30, 2024 as compared to 2023 was primarily attributable to our adoption of the guidance contained in a Notice of Proposed Rule Making issued during the third quarter of 2023 by the United States Internal Revenue Service ("the Notice"). See further discussion of the Notice in Note 12, "Income Taxes" to the condensed consolidated financial statements included in this Form 10-Q.

R&D expenses, including non-cash share-based compensation costs, were $470.8 million for the six months ended June 30, 2024, compared to $143.0 million for the six months ended June 30, 2023. The increase of $327.8 million was primarily due to non-cash expense of $171.9 million paid to Knopp for a milestone and royalty buyback related to the BHV-7000 and broader Kv7 platform that was recognized during the three months ended June 30, 2024 (the buyback reduced our potential future milestone payments by $867.5 million, and replaced the scaled high single digit to low teens royalty payment obligations with a flat royalty payment in the mid-single digits for the Kv7 programs).

The increase in expense was also related to advancing our 6 clinical platforms including 5 phase 3 starts for BHV-7000, follow-on Kv7 assets, preclinical research programs, and increases in direct program spend for additional and advancing multiple clinical development programs in 2024, as compared to the same period in the prior year. The $22.6 million increase in expense for BHV-1510 was primarily due to the Pyramid Acquisition, which resulted in $10.9 million (non-cash) of expense recorded to R&D during the six months ended June 30, 2024, a $1.5 million milestone payment which became due during the first quarter of 2024, and a $5.7 million non-cash milestone payment which became due during the first quarter of 2024.
Non-cash share-based compensation expense was $28.4 million for the six months ended June 30, 2024, an increase of $23.7 million as compared to the same period in 2023. Non-cash share-based compensation expense was higher in the 2024 primarily due to our annual equity incentive awards granted in the fourth quarter of 2023 and first quarter of 2024.
General and Administrative Expenses
G&A expenses, including non-cash share-based compensation costs, were $46.2 million for the six months ended June 30, 2024, compared to $28.8 million for the six months ended June 30, 2023. The increase of $17.4 million was primarily due to increased non-cash share-based compensation expense. Non-cash share-based compensation expense was $18.7 million for the six months ended June 30, 2024, an increase of $15.0 million as compared to the same period in 2023. Non-cash share-based compensation expense was higher in 2024 primarily due to our annual equity incentive awards being granted in the fourth quarter of 2023 and the first quarter of 2024.
Other Income , Net
Other income, net was a net income of $18.5 million for the six months ended June 30, 2024, compared to $14.1 million for the six months ended June 30, 2023. The increase was primarily due to a $9.2 million gain recorded upon settlement of our forward contract liability for the 2024 Additional Consideration issued
under the Knopp Amendment, and increased investment income. This was partially offset by a decrease of $5.6 million in other income recognized during the six months ended June 30, 2024 as compared to the same period in 2023 related to the Transition Services Agreement entered into with the Former Parent. See Note 4, "Fair Value of Financial Assets and Liabilities" to the accompanying condensed consolidated financial statements included in this Form 10-Q for discussion of the forward contract and derivative liabilities recorded in connection with the Knopp Amendment.
Provision for Income Taxes
We recorded an income tax provision of $0.7 million for the six months ended June 30, 2024, compared to an income tax provision of $3.1 million for the six months ended June 30, 2023. The decrease in income tax expense for the six months ended June 30, 2024 as compared to 2023 was primarily attributable to our adoption of the Notice. See further discussion of the Notice in Note 12, "Income Taxes" to the condensed consolidated financial statements included in this Form 10-Q.
Liquidity and Capital Resources
Since our inception, we have not generated any revenue and have incurred significant operating losses and negative cash flows from operations. We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for our product candidates. We expect to continue to incur significant expenses for at least the next several years as we advance our product candidates from discovery through preclinical development and clinical trials and seek regulatory approval and pursue commercialization of any approved product candidate. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. In addition, we may incur expenses in connection with the in-license or acquisition of additional product candidates
Historically, we have funded our operations primarily with the cash contribution received from the Former Parent at the Separation and proceeds from the sale of our common shares. We have incurred recurring losses since our inception and expect to continue to generate operating losses for the foreseeable future.
As of June 30, 2024, we had cash and cash equivalents of $239.1 million and marketable securities of $197.8 million. Cash in excess of immediate requirements is invested in marketable securities and money market funds with a view to liquidity and capital preservation. We continuously assess our working capital needs, capital expenditure requirements, and future investments or acquisitions.

Operating Activities
Net cash used in operating activities was $270.4 million for the six months ended June 30, 2024 and $122.0 million for the six months ended June 30, 2023. The $148.4 million increase in net cash used in operating activities for the six months ended June 30, 2024 was primarily due to an increase in R&D spending to advance our 6 clinical platforms including 5 phase 3 starts for BHV-7000, follow-on Kv7 assets, preclinical research programs, and increases in direct program spend for additional and advancing multiple clinical development programs in 2024, as compared to the same period in the prior year. The R&D spend during the period includes $2.5 million in milestone payments for BHV-1510 and BHV-1300.
Investing Activities
Net cash used in investing activities was $63.9 million for the six months ended June 30, 2024, compared to net cash provided by investing activities of $75.2 million for the six months ended June 30, 2023. The $139.1 million increase in net cash used in investing activities for the six months ended June 30, 2024 was primarily driven by an increase in purchases of marketable securities with cash in excess of immediate requirements, partially offset by an increase in maturities of marketable securities (see Note 3, "Marketable Securities," to the Condensed Consolidated Financial Statements for additional details), as compared to the same period in the prior year.
Financing Activities
Net cash provided by financing activities was $324.5 million for the six months ended June 30, 2024 compared to $6.3 million for the six months ended June 30, 2023. The $318.2 million increase in net cash provided by financing activities for the six months ended
June 30, 2024 was primarily driven by an increase in proceeds from the issuance of common shares from our April 2023 public equity offering and Equity Distribution Agreement, both during the second quarter of 2024, as compared to the same period in the prior year.
April 2024 Public Offering
On April 22, 2024, we closed an underwritten public offering of 6,451,220 of its common shares, which included the exercise in full of the underwriters' option to purchase additional shares, at a price to the public of $41.00 per share. The net proceeds raised in the offering, after deducting underwriting discounts and expenses of the offering payable by us, were approximately $247.8 million. We intend to use the net proceeds received from the offering for general corporate purposes.
Equity Distribution Agreement
In October 2023, we entered into an equity distribution agreement pursuant to which we may offer and sell common shares having an aggregate offering price of up to $150.0 million from time to time through or to the sales agent, acting as our agent or principal (the "Equity Distribution Agreement"). Sales of our common shares, if any, will be made in sales deemed to be “at-the-market offerings”. The sales agent is not required to sell any specific amount of securities but will act as our sales agent using commercially reasonable efforts consistent with its normal trading and sales practices, on mutually agreed terms between the sales agent and us. We currently plan to use the net proceeds from any at-the-market offerings of our common shares for general corporate purposes.
As of June 30, 2024, we have sold and issued 2,093,731 common shares under the Equity Distribution Agreement for net proceeds of approximately $69,890. Subsequent to June 30, 2024, we have issued and sold an additional 2,154,857 common shares for net proceeds of $76,360. As of August 9, 2024, the date of this report, the we have issued and sold a total of 4,248,588 common shares under the Equity Distribution Agreement for total net proceeds of $146,250, and no shares remain available to be issued.
Knopp Amendment
In May 2024, we entered into the Knopp Amendment which reduced our potential future milestone payments by $867.5 million, and replaced the scaled high single digit to low teens royalty payment obligations with a flat royalty payment in the mid-single digits for our Kv7 programs. As consideration, we agreed to issue to Knopp the 2024 Additional Consideration and 2025 Additional Consideration, both non-cash common share payments, as well as agreed to one-time cash-true ups for both the 2024 Additional Consideration and 2025 Additional Consideration. See Recent Developments elsewhere in this Current Report on Form 10-Q for additional information on the Knopp Amendment.
45
On May 30, we issued 1,872,874 common shares valued at $66.0 million to Knopp to settle the forward contract liability related to the 2024 Additional Consideration and recognized a non-cash gain of $9.2 million on settlement. We expect to issue the common shares representing the 2025 Additional Consideration on or before June 30, 2025, in accordance with the Knopp Amendment.
In the event that Knopp continues to hold the shares of the Company's common shares representing the 2024 Additional Consideration and 2025 Additional Consideration on December 1, 2024 and 2025, respectively, and the Market Price declines relative to the respective Reference Price, both as defined in the agreement, we would be responsible for a cash payment equal to the difference.
Knopp Warrant
As further consideration under the Knopp Amendment, we issued to Knopp a warrant to purchase 294,195 of the Company's common shares with a purchase price of $67.98, subject to certain specified development milestones and the Company achieving a specified market capitalization.
As of June 30, 2024, the vesting conditions have not been met and the warrant is still outstanding.
Funding Requirements
We expect our expenses to increase in connection with our ongoing activities, particularly as we advance and expand preclinical activities, clinical trials and potential commercialization of our product candidates. Our costs will also increase as we:
•continue to advance and expand the development of our discovery programs and clinical-stage assets;
•continue to initiate and progress other supporting studies required for regulatory approval of our product candidates, including long-term safety studies, drug-drug interaction studies, preclinical toxicology and carcinogenicity studies;
•initiate preclinical studies and clinical trials for any additional indications for our current product candidates and any future product candidates that we may pursue;
•continue to build our portfolio of product candidates through the acquisition or in-license of additional product candidates or technologies;
•continue to develop, maintain, expand and protect our intellectual property portfolio;
•pursue regulatory approvals for our current and future product candidates that successfully complete clinical trials;
•establish and support our sales, marketing and distribution infrastructure to commercialize any future product candidates for which we may obtain marketing approval; and
•hire additional clinical, medical, commercial, and development personnel.
We expect that our cash, cash equivalents and marketable securities, as of the date of this Quarterly Report on Form 10-Q, will be sufficient to fund operating and financial commitments and other cash requirements for more than one year. We expect we will need to raise additional capital until we are profitable. If no additional capital is raised through either public or private equity financings, debt financings, strategic relationships, alliances and licensing agreements, or a combination thereof, we may delay, limit or reduce discretionary spending in areas related to research and development activities and other general and administrative expenses in order to fund our operating costs and working capital needs.
We have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. We expect that we will require additional capital to pursue in-licenses or acquisitions of other product candidates. If we receive regulatory approval for our product candidates, we expect to incur commercialization expenses related to product manufacturing, sales, marketing and distribution, depending on where we choose to commercialize or whether we commercialize jointly or on our own.
Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical product candidates, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on and could increase significantly as a result of many factors, including:
•the scope, progress, results and costs of researching and developing our product candidates, and conducting preclinical studies and clinical trials;
•the costs, timing and outcome of regulatory review of our product candidates;
•the costs and timing of hiring new employees to support our continued growth;
•the costs of preparing, filing, and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;
•the extent to which we acquire or in-license other product candidates and technologies;
•the timing, receipt and amount of sales of, or milestone payments related to or royalties on,
46
our current or future product candidates, if any; and
•other capital expenditures, working capital requirements, and other general corporate activities.
Until such time, if ever, that we can generate product revenue sufficient to achieve profitability, we expect to finance our cash needs through a combination of public and private equity offerings, debt financings, other third-party funding, strategic alliances, licensing arrangements or marketing and distribution arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our existing shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing shareholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through other third-party funding, strategic alliances, licensing arrangements or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us.
Contractual Obligations and Commitments
Except as discussed in Note 11, "Commitments and Contingencies" to our Condensed Consolidated Financial Statements included in Item 1, “Unaudited Condensed Consolidated Financial Statements,” of this Quarterly Report on Form 10-Q, there have been no material changes to our contractual obligations and commitments as included in our audited consolidated financial statements included in the 2023 Form 10-K.
Critical Accounting Policies and Significant Judgments and Estimates
We have prepared our condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States ("GAAP"). Our preparation of our condensed consolidated financial statements requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets, liabilities, expenses, and related disclosures at the date of the condensed consolidated financial statements. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially
from these estimates under different assumptions or conditions.
Excluding the discussion below, during the six months ended June 30, 2024, there were no material changes to our critical accounting policies as reported in our annual consolidated financial statements included in the 2023 Form 10-K.
Valuation of Forward Contract and Derivative Liabilities
We have accounted for certain consideration agreed to in connection with the Knopp Amendment as forward contracts and derivative liabilities. The fair value of these liabilities have been determined based on Monte Carlo simulations of Biohaven's share price, which requires judgment and assumptions on the volatility of our share price, discounted to present value using a risk-free rate plus Biohaven specific credit risk as they are payable in either cash or a variable number of shares.
Our expectations of the volatility of Biohaven's share price at the reporting date could be materially different than our actual future volatility, and if so, would mean the estimated fair value could be significantly higher or lower than the fair value determined.
Recently Issued Accounting Pronouncements
A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations, if applicable, is disclosed in Note 2 to our condensed consolidated financial statements appearing at the beginning of this Quarterly Report on Form 10-Q.
Item 3. Quantitative and Qualitative Disclosures about Market Risks
Foreign Currency Translation
Our operations include activities in countries outside the U.S. As a result, our financial results are impacted by factors such as changes in foreign currency exchange rates or weak economic conditions in the foreign markets where we operate. Our monetary exposures on our balance sheet are currently immaterial to our financial position as of June 30, 2024.
We do not engage in any hedging activities against changes in foreign currency exchange rates.
Interest Rate Risk
As of June 30, 2024, we invest our excess cash balances in marketable securities of highly rated financial institutions and investment-grade debt instruments. We seek to diversify our investments and limit the amount of investment concentrations for individual institutions, maturities and investment types. Most of our interest-bearing securities are subject to interest rate risk and could decline in value if interest rates fluctuate. Based on the type of securities we hold,
47
we do not believe a change in interest rates would have a material impact on our financial statements. If interest rates were to increase or decrease by 1.00%, the fair value of our investment portfolio would (decrease) increase by approximately $(0.4) million and $0.4 million, respectively.
We do not engage in any hedging activities against changes in interest rates.
Equity Price Risk
We hold financial liabilities in the form of derivative liabilities related to the potential one-time cash true-up payments under the Knopp Amendment that are measured at fair value and recorded through net income (loss) in our condensed consolidated statement of operations and comprehensive loss. A primary driver of the fair value of these derivative liabilities is our 20-day volume weighted average share price ("VWAP") relative to the Reference Price, as defined in the agreement. A decrease in our 20-day VWAP relative to the Reference Price would result in an increase in the fair value of the liabilities.
Further information regarding the fair value of these financial liabilities that are measured at fair value on a recurring basis, and the unobservable inputs used in the valuation of these financial liabilities, is presented in Note 4, "Fair Value of Financial Assets and Liabilities" and Note 10, "License, Acquisitions and Other Agreements" to the accompanying condensed consolidated financial statements included in this Form 10-Q.
Credit Risk
Financial instruments that potentially expose the Company to concentrations of credit risk consist of cash, cash equivalents, and short-term debt securities. The Company maintains a portion of its cash deposits in government insured institutions in excess of government insured limits. The Company deposits its cash in financial institutions that it believes have high credit quality and has not experienced any losses on such accounts. The Company's cash management policy permits investments in U.S. federal government and federal agency securities, corporate bonds or commercial paper, supranational and sovereign obligations, certain qualifying money market mutual funds, certain repurchase agreements, and places restrictions on credit ratings, maturities, and concentration by type and issuer. The Company is exposed to credit risk in the event of a default by the financial institutions holding its cash in excess of government insured limits and in the event of default by corporations and governments in which it holds investments in cash equivalents and short-term debt securities, to the extent recorded on the condensed consolidated balance sheet.
We have not experienced any credit losses or recorded any allowance for credit losses related to our cash, cash equivalents, and short-term debt securities.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, refers to controls and procedures that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to a company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.
In designing and evaluating our disclosure controls and procedures, management recognizes that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and not be detected.
Based on the evaluation of our disclosure controls and procedures as of June 30, 2024, our Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2024, our disclosure controls and procedures were effective at the reasonable assurance level.
Changes in Internal Controls over Financial Reporting
There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended June 30, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
48
PART II — OTHER INFORMATION
Item 1. Legal Proceedings
From time to time, we may be subject to litigation and claims arising in the ordinary course of business. We are not currently a party to any material legal proceedings, and we are not aware of any pending or threatened legal proceeding against us that we believe could have a material adverse effect on our business, operating results, cash flows or financial condition.
Item 1A.  Risk Factors
Our business is subject to risks and events that, if they occur, could adversely affect our financial condition and results of operations and the trading price of our securities. Our risk factors have not changed materially from those described in "Part I, Item 1A. Risk Factors" of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on February 29, 2024.
Item 2. Unregistered Sales of Equity Securities, Use of Proceeds, and Issuer Purchases of Equity Securities
Pyramid Agreement
In January 2024, we acquired Pyramid Biosciences, Inc. ("Pyramid"), pursuant to an Agreement and Plan of Merger, dated January 7, 2024 (the "Pyramid Agreement"). In consideration for the Pyramid acquisition we made an upfront payment of 255,794 of our common shares. As of June 30, 2024, 253,410 of these common shares have been issued by the Company, including 10,452 shares that were issued in the second quarter of 2024. We also agreed to make additional success-based payments upon the achievement of certain regulatory milestones, which we may elect to pay in cash or our common shares. In January 2024, a payment became due to Pyramid related to achievement of a developmental milestone under the Pyramid Agreement, which we elected to pay in 98,129 of our common shares. As of June 30, 2024, 97,233 of these common shares have been issued by the Company. The shares related to both of these payments were not registered under the Securities Act upon issuance, and a portion of the shares were subsequently registered under our Registration Statement on Form S-3.
Pyramid represented that, among other things, it is an institutional accredited investor as defined in Rule 501(a) of Regulation D of the Securities Act. The foregoing shares shall be issued in reliance on the private offering exemption provided by Section 4(a)(2) of the Securities Act. See Note 10, "License, Acquisitions and Other Agreements," to the Condensed Consolidated Financial Statements appearing elsewhere in this report for additional details on this transaction.
Amendment to Knopp Purchase Agreement
In May 2024, we entered into an amendment (the “Amendment”) to our existing Membership Interest Purchase Agreement, dated as of February 24, 2022, with Knopp Biosciences LLC (“Knopp”) in order to make certain changes to the royalty payment obligations and success-based payments. See Item 5, “Other Information” for additional information related to the Amendment.

In connection with the Amendment, we issued to Knopp 1,872,874 of our common shares, valued at approximately $75 million, through a private placement within 60 days of the date of execution of the Amendment (the “2024 Additional Consideration”). We also agreed to issue additional shares of our common shares, valued at approximately $75 million, within 60 days of the first anniversary of execution of the Amendment (the “2025 Additional Consideration”). In addition, we issued to Knopp a warrant (the "Warrant") to purchase 294,195 of our common shares at a purchase price per share of $67.98, subject to certain specified development milestones and achieving a specified market capitalization.

The foregoing issuance and sale of our common shares in connection with the execution of the Amendment and the Warrant have not been registered under the Securities Act of 1933 (the “Securities Act”) or any state securities laws. We have relied on the exemption from the registration requirements of the Securities Act under Section 4(a)(2) thereof, for a transaction by an issuer not involving any public offering.

Item 5. Other Information
Rule 10b5-1 Trading Plans
During the quarter ended June 30, 2024, none of our directors or officers adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408 of Regulation S-K.

In no event shall any Regulatory Milestone Payment be paid more than once other than with respect to the Regulatory Milestone set forth in Section 2.4(a)(ix), [***].”
8.Additional Consideration True-Up Payments. A new Section 2.5.1 is hereby added to the Agreement as follows:

Seller acknowledges and agrees that it shall not be entitled to receive the 2025 True-Up Payment if the condition in the proviso in the foregoing sentence is violated.
(iii) In the event that Parent changes the number of Parent Shares or securities convertible or exchangeable into or exercisable for Parent Shares issued and outstanding prior to December 1, 2025 as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, issuer tender or exchange offer or other similar transaction, the 2025 True-Up Payment shall be equitably adjusted.”

Buyer shall use reasonable best efforts to maintain the effectiveness of such Registration Statement for a period ending on the date the Seller no longer holds more than 10,000 Registrable Shares.
(b)For not more than sixty (60) consecutive days or for a total of not more than one hundred twenty (120) days in any twelve (12) month period, Parent may suspend the use of any prospectus supplement included in any Registration Statement contemplated by this Section in the event that Parent determines in good faith that such suspension is necessary to (A) delay the disclosure of material non-public information concerning Parent, the disclosure of which at the time is not, in the good faith opinion of Parent, in the best interests of Parent or (B) amend or supplement the affected Registration Statement or the related prospectus or prospectus supplement so that such Registration Statement, prospectus or prospectus supplement shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the case of the prospectus and prospectus supplement in light of the circumstances under which they were made, not misleading (an “Allowed Delay”); provided, that Parent shall promptly (i) notify Seller in writing of the commencement of an Allowed Delay, but shall not disclose to Seller any material non-public information giving rise to an Allowed Delay, (ii) advise Seller in writing to cease all sales under such Registration Statement until the end of the Allowed Delay and (iii) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable.”

(a)Authority; Approval. Seller has all requisite corporate or similar power and authority and has taken all corporate or similar action necessary in order to execute, deliver and perform its obligations under this Amendment and each of the Transaction Documents to which it is a party. This Amendment has been duly executed and delivered by Seller and, when executed and delivered by the Buyer Parties, will constitute a valid and binding agreement of Seller enforceable against Seller in accordance with its terms, subject to the Bankruptcy and Equity Exception. The Board of Managers of Seller has approved this Amendment. No other company or equity holder proceedings are necessary to authorize this Amendment or to consummate the Transactions.
(b)Governmental Filings; No Violations.
(i) Other than the filings, notices, reports, consents, registrations, approvals, permits, expirations of waiting periods or authorizations which may be required (i) under the HSR Act, the Exchange Act and the Securities Act or state securities, takeover and “blue sky” Laws or (ii) to be made with the NYSE (collectively, the “Seller Approvals”), no expirations of waiting periods under applicable Laws are required and no notices, reports or other filings are required to be made by Seller with, nor are any consents, registrations, approvals, permits or authorizations required to be obtained by Seller from, any Governmental Entity in connection with the execution, delivery and performance of this Amendment by Seller or the consummation of the transactions contemplated by this Amendment.
(ii) The execution, delivery and performance of this Amendment by Seller does not conflict with, or result in any breach or violation of or default (with or without notice, lapse of time, or both) under, or give rise to any right of termination, loss of rights, adverse modification of provisions, cancellation or acceleration of any obligation under, or result in the creation of a Lien on any of the assets of Seller under any provision of (i) the Organizational Documents of Seller, (ii) any Contract binding upon Seller or (iii) assuming (solely with respect to performance of this Agreement and the Transaction Documents and consummation of the Transactions) receipt of the Seller Approvals, any Laws to which Seller is subject, except, in the case of clauses (ii) and (iii) above, for any breach, violation, default, termination, loss, adverse modification, cancellation, acceleration or creation that would not, individually or in the aggregate, reasonably be expected to be prevent, materially delay or materially impair the transactions contemplated by this Amendment.
(c)Purchase Entirely for Own Account. Seller acknowledges that the Additional Consideration Shares shall be acquired for investment for Seller’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and Seller has no present intention of selling, granting any participation or otherwise distributing such Parent Shares. Seller can bear the economic risk of an investment in such Parent Shares indefinitely and a total loss with respect to
    - 8 -


such investment. Seller does not have any contract, undertaking, agreement, arrangement or understanding with any Person to sell, transfer or grant participation to a Person any of such Parent Shares.
(d)Investment Experience and Accredited Investor Status. Seller is an “accredited investor” (as defined in Regulation D under the Securities Act). Seller has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Additional Consideration Shares.

Seller represents that it is familiar with Rule 144. Seller understands that such Parent Shares are being offered and issued to it in reliance on specific exemptions from the registration requirements of United States federal and state securities Laws and Buyer is relying in part upon the truth and accuracy of, and Seller’s compliance with, the representations, warranties, agreements, acknowledgements and understandings of Seller set forth in this Agreement in order to determine the availability of such exemptions and the eligibility of Seller to acquire such Parent Shares.

2.Term of Warrant.
(a) Subject to the terms and conditions hereof and the satisfaction of the Vesting Conditions described in clause (b) as to the applicable Warrant Shares, at any time or from time to time thereafter and prior to 5:00 p.m., New York time, on the tenth (10th) anniversary of the date hereof or, if such day is not a Business Day, on the closest preceding Business Day (the “Exercise Period”), the Holder of this Warrant may exercise this Warrant for all or any part of the vested Warrant Shares purchasable hereunder (subject to adjustment as provided herein).
(b) This Warrant shall be subject to achievement of both of the following vesting conditions (the “Vesting Conditions”):
(i) [***]; and
(ii) [***].
Notwithstanding the foregoing, this Warrant shall become fully vested and shall be automatically exercised pursuant to Section 3(b)(ii) immediately prior to the consummation of a Change of Control.
3.Exercise of Warrant.
(a) Exercise Procedure. This Warrant may be exercised from time to time on any Business Day during the Exercise Period, for all or any part of the unexercised Warrant Shares into which it is then exercisable, upon:
(i) surrender of this Warrant to the Company at its then principal executive offices (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction), together with an Exercise Notice in the form attached hereto as Exhibit A (each, an “Exercise Notice”), duly completed (including specifying the number of Warrant Shares to be purchased) and executed; and
(ii) payment to the Company of the Aggregate Exercise Price in accordance with Section 3(b).
(b) Payment of the Aggregate Exercise Price. Payment of the Aggregate Exercise Price shall be made, at the option of the Holder as expressed in the Exercise Notice, by the following methods:
(i) by delivery to the Company of a certified or official bank check payable to the order of the Company or by wire transfer of immediately available funds to an account designated in writing by the Company, in the amount of such Aggregate Exercise Price; or
(ii) by instructing the Company to issue Warrant Shares then issuable upon all or any part of this Warrant on a net basis under clause (ii) such that, without payment of any cash consideration or other immediately available funds, the Holder shall surrender this
    20



Warrant in exchange for the number of Warrant Shares as is computed using the following formula:
X = Y(A-B) ÷ A
where:
X = the number of Warrant Shares to be issued to the Holder;
Y = the total number of Warrant Shares for which the Holder has elected to exercise this Warrant pursuant to Section 3(a);
A = the Fair Market Value of one Warrant Share as of the applicable Exercise Date; and
B = the Exercise Price in effect under this Warrant as of the applicable Exercise Date.
In the event of any withholding of Warrant Shares to effect a net settlement pursuant to clause (ii) above where the number of shares issuable thereunder is not a whole number, the number of shares issued by the Company on a net basis shall be rounded down to the nearest whole share and the Company shall make a cash payment to the Holder (by delivery of a certified or official bank check or by wire transfer of immediately available funds) based on the incremental fraction of a share being so withheld by the Company in an amount equal to the product of (x) such incremental fraction of a share being so withheld multiplied by (y) the Fair Market Value per Warrant Share as of the Exercise Date.
(c) Fractional Shares. The Company shall not be required to issue a fractional Warrant Share upon exercise of any Warrant. As to any fraction of a Warrant Share that the Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay to such Holder an amount in cash (by delivery of a certified or official bank check or by wire transfer of immediately available funds) equal to the product of (i) such fraction multiplied by (ii) the Fair Market Value of one Warrant Share on the Exercise Date.
(d) Delivery of New Warrant. Unless the purchase rights represented by this Warrant shall have expired or shall have been fully exercised, the Company shall, at the time of delivery of the certificate or certificates representing the Warrant Shares being issued in accordance with Section 3 hereof, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unexpired and unexercised Warrant Shares called for by this Warrant. Such new Warrant shall in all other respects be identical to this Warrant.
(e) Valid Issuance of Warrant and Warrant Shares; Payment of Taxes. With respect to the exercise of this warrant, the Company hereby represents, covenants and agrees:
(i) This Warrant is, and any Warrant issued in substitution for or replacement of this Warrant shall be, upon issuance, duly authorized and validly issued.
(ii) All Warrant Shares issuable upon the exercise of this Warrant pursuant to the terms hereof shall be, upon issuance, and the Company shall take all such actions as may be necessary or appropriate in order that such Warrant Shares are, validly issued, fully paid
    21



and non-assessable, issued without violation of any preemptive or similar rights of any shareholder of the Company and free and clear of all taxes, liens and charges.
(iii) The Company shall take all such actions as may be necessary to ensure that all such Warrant Shares are issued without violation by the Company of any applicable law or governmental regulation or any requirements of any primary securities exchange upon which Common Shares or other securities constituting Warrant Shares may be listed at the time of such exercise (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance).
(iv) The Company shall use reasonable commercial efforts to cause the Warrant Shares, immediately upon such exercise, to be listed on any primary securities exchange upon which Common Shares or other securities constituting Warrant Shares are listed at the time of such exercise.
(v) The Company shall pay all expenses in connection with, and all taxes and other governmental charges that may be imposed with respect to, the issuance or delivery of Warrant Shares upon exercise of this Warrant; provided, that the Company shall not be required to pay any tax or governmental charge that may be imposed with respect to any applicable withholding or the issuance or delivery of the Warrant Shares to any Person other than the Holder, and no such issuance or delivery shall be made unless and until the Person requesting such issuance has paid to the Company the amount of any such tax, or has established to the satisfaction of the Company that such tax has been paid.
(f) Conditional Exercise. Notwithstanding any other provision hereof, if an exercise of any portion of this Warrant is to be made in connection with a sale of the Company (pursuant to a merger, sale of stock, or otherwise), such exercise may at the election of the Holder be conditioned upon the consummation of such transaction, in which case such exercise shall not be deemed to be effective until immediately prior to the consummation of such transaction.
(g) Reservation of Shares. During the Exercise Period, the Company shall at all times reserve and keep available out of its authorized but unissued Common Shares or other securities constituting Warrant Shares, solely for the purpose of issuance upon the exercise of this Warrant, the maximum number of Warrant Shares issuable upon the exercise of this Warrant.
4.Adjustment to Exercise Price and Number of Warrant Shares. The Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as provided in this Section 4 (in each case, after taking into consideration any prior adjustments pursuant to this Section 4).
(a) Adjustment to Exercise Price and Warrant Shares Upon Dividend, Subdivision or Combination of Common Shares. If the Company shall, at any time or from time to time after the Original Issue Date, (i) pay a dividend or make any other distribution upon the Common Shares or any other capital stock of the Company that is payable in Common Shares, or (ii) subdivide (by any stock split, recapitalization or otherwise) its outstanding Common Shares into a greater number of shares, the Exercise Price in effect
    22



immediately prior to any such dividend, distribution or subdivision shall be proportionately reduced and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately increased. If the Company at any time combines (by combination, reverse stock split or otherwise) its outstanding Common Shares into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately decreased. Any adjustment under this Section 4(a) shall become effective at the close of business on the date the dividend, subdivision or combination becomes effective.
(b) Adjustment to Exercise Price and Warrant Shares Upon Reorganization, Reclassification, Consolidation or Merger. In the event of any (i) capital reorganization of the Company, (ii) reclassification of the stock of the Company (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), (iii) consolidation or merger of the Company with or into another Person, (iv) sale of all or substantially all of the Company’s assets to another Person or (v) other similar transaction (other than any such transaction covered by Section 4(a) or any Change of Control, which shall be governed by Section 2), in each case which entitles the holders of Common Shares to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Shares, each Warrant shall, immediately after such reorganization, reclassification, consolidation, merger, sale or similar transaction, remain outstanding and shall thereafter, in lieu of or in addition to (as the case may be) the number of Warrant Shares then exercisable under this Warrant, be exercisable for the kind and number of shares of stock or other securities or assets of the Company or of the successor Person resulting from such transaction to which the Holder would have been entitled upon such reorganization, reclassification, consolidation, merger, sale or similar transaction if the Holder had exercised this Warrant in full immediately prior to the time of such reorganization, reclassification, consolidation, merger, sale or similar transaction and acquired the applicable number of Warrant Shares then issuable hereunder as a result of such exercise (without taking into account any limitations or restrictions on the exercisability of this Warrant); and, in such case, appropriate adjustment (in form and substance satisfactory to the Holder) shall be made with respect to the Holder’s rights under this Warrant to insure that the provisions of this Section 4 hereof shall thereafter be applicable, as nearly as possible, to this Warrant in relation to any shares of stock, securities or assets thereafter acquirable upon exercise of this Warrant (including, in the case of any consolidation, merger, sale or similar transaction in which the successor or purchasing Person is other than the Company, an immediate adjustment in the Exercise Price to the value per share for the Common Shares reflected by the terms of such consolidation, merger, sale or similar transaction, and a corresponding immediate adjustment to the number of Warrant Shares acquirable upon exercise of this Warrant without regard to any limitations or restrictions on exercise, if the value so reflected is less than the Exercise Price in effect immediately prior to such consolidation, merger, sale or similar transaction). The provisions of this Section 4(b) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales or similar transactions. The Company shall not effect any such reorganization, reclassification, consolidation, merger, sale or similar transaction unless, prior to the consummation thereof, the successor Person (if other than the
    23



Company) resulting from such reorganization, reclassification, consolidation, merger, sale or similar transaction, shall assume, by written instrument substantially similar in form and substance to this Warrant and satisfactory to the Holder, the obligation to deliver to the Holder such shares of stock, securities or assets which, in accordance with the foregoing provisions, such Holder shall be entitled to receive upon exercise of this Warrant. Notwithstanding anything to the contrary contained herein, with respect to any corporate event or other transaction contemplated by the provisions of this Section 4(b), the Holder shall have the right to elect prior to the consummation of such event or transaction, to give effect to the exercise rights contained in Section 2 instead of giving effect to the provisions contained in this Section 4(b) with respect to this Warrant.
(c) Certificate as to Adjustment.
(i) As promptly as reasonably practicable following any adjustment of the Exercise Price, but in any event not later than five (5) Business Days thereafter, the Company shall furnish to the Holder a certificate of an executive officer setting forth in reasonable detail such adjustment and the facts upon which it is based and certifying the calculation thereof. As promptly as reasonably practicable following the receipt by the Company of a written request by the Holder, but in any event not later than five (5) Business Days thereafter, the Company shall furnish to the Holder a certificate of an executive officer certifying the Exercise Price then in effect and the number of Warrant Shares or the amount, if any, of other shares of stock, securities or assets then issuable upon exercise of the Warrant.
6.Transfer of Warrant. Subject to the transfer conditions referred to in the legend endorsed hereon, this Warrant and all rights hereunder are transferable, in whole or in part, by the Holder without charge to the Holder, upon surrender of this Warrant to the Company at its then principal executive offices with a properly completed and duly executed Assignment in the form attached hereto as Exhibit B, together with funds sufficient to pay any transfer taxes described in Section 3(e)(v) in connection with the making of such transfer. Upon such compliance, surrender and delivery and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant, if any, not so assigned and this Warrant shall promptly be cancelled.
7.Holder Not Deemed a Shareholder; Limitations on Liability. Except as otherwise specifically provided herein and for common shares held directly by Holder not subject to this Warrant, prior to the issuance to the Holder of the Warrant Shares which the Holder is then entitled to receive upon the due exercise of this Warrant, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of shares of capital stock of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, as such, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of
    24



the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

8.Replacement on Loss; Division and Combination.
(a) Replacement of Warrant on Loss. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and upon delivery of an indemnity reasonably satisfactory to it (it being understood that a written indemnification agreement or affidavit of loss of the Holder shall be a sufficient indemnity) and, in case of mutilation, upon surrender of such Warrant for cancellation to the Company, the Company at its own expense shall execute and deliver to the Holder, in lieu hereof, a new Warrant of like tenor and exercisable for an equivalent number of Warrant Shares as the Warrant so lost, stolen, mutilated or destroyed; provided, that, in the case of mutilation, no indemnity shall be required if this Warrant in identifiable form is surrendered to the Company for cancellation.
(b) Division and Combination of Warrant. Subject to compliance with the applicable provisions of this Warrant as to any transfer or other assignment which may be involved in such division or combination, this Warrant may be divided or, following any such division of this Warrant, subsequently combined with other Warrants, upon the surrender of this Warrant or Warrants to the Company at its then principal executive offices, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the respective Holders or their agents or attorneys. Subject to compliance with the applicable provisions of this Warrant as to any transfer or assignment which may be involved in such division or combination, the Company shall at its own expense execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants so surrendered in accordance with such notice. Such new Warrant or Warrants shall be of like tenor to the surrendered Warrant or Warrants and shall be exercisable in the aggregate for an equivalent number of Warrant Shares as the Warrant or Warrants so surrendered in accordance with such notice.
9.No Impairment. The Company shall not, by amendment of its Memorandum and Articles of Association, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but shall at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the Holder in order to protect the exercise rights of the Holder against dilution or other impairment, consistent with the tenor and purpose of this Warrant.
10.Compliance with the Securities Act.
(a) Agreement to Comply with the Securities Act; Legend. The Holder, by acceptance of this Warrant, agrees to comply in all respects with the provisions of this Section 10 and the restrictive legend requirements set forth on the face of this Warrant and further agrees that such Holder shall not offer, sell or otherwise dispose of this Warrant or any
    25



Warrant Shares to be issued upon exercise hereof except under circumstances that will not result in a violation of the Securities Act of 1933, as amended (the “Securities Act”). This Warrant and all Warrant Shares issued upon exercise of this Warrant (unless registered under the Securities Act) shall be stamped or imprinted with a legend in substantially the following form:
“THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR QUALIFIED UNDER ANY STATE OR FOREIGN SECURITIES LAWS AND MAY NOT BE OFFERED FOR SALE, SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED OR ASSIGNED UNLESS (I) A REGISTRATION STATEMENT COVERING SUCH SHARES IS EFFECTIVE UNDER THE ACT AND IS QUALIFIED UNDER APPLICABLE STATE AND FOREIGN LAW OR (II) THE TRANSACTION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS UNDER THE ACT AND THE QUALIFICATION REQUIREMENTS UNDER APPLICABLE STATE AND FOREIGN LAW AND, IF THE COMPANY REQUESTS, AN OPINION SATISFACTORY TO THE COMPANY TO SUCH EFFECT HAS BEEN RENDERED BY COUNSEL.”
Notwithstanding the forgoing, certificates evidencing the Warrant Shares shall not be required to contain such legend, (i) while a registration statement covering the resale of such Warrant Shares is effective under the Securities Act, (ii) following any sale of such Warrant Shares pursuant to Rule 144 (assuming cashless exercise of the Warrants), or (iii) if such Warrant Shares are eligible for sale under Rule 144 (assuming cashless exercise of the Warrants) (provided, however, that in the case of (i), (ii) and (iii), above, the holder provides the Company with customary legal representation letters reasonably acceptable to the Company). Whenever such restrictions shall cease and terminate as to any such Warrant Shares, the holder of such Warrant Shares shall be entitled to receive from the Company upon a written request in writing, without expense, new securities of like tenor not bearing the legend set forth herein. The Company shall cooperate with any holder of such Warrant Shares and, to the extent applicable, facilitate the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Warrant Shares and enable such certificates to be in such denominations or amounts, as the case may be, as the holder may reasonably request and registered in such names as such holder may request. Notwithstanding the forgoing, the Company’s obligations under this Section 10 with respect to Warrant Shares that may be sold under Rule 144 are contingent on the Company’s receipt from Holder of a customary Rule 144 representation letter in form and substance reasonably acceptable to the Company.
(b) Representations of the Holder. In connection with the issuance of this Warrant, the Holder specifically represents, as of the date hereof, to the Company by acceptance of this Warrant as follows:
(i) The Holder is an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act. The Holder is acquiring this Warrant and the Warrant Shares to be issued upon exercise hereof for investment for its own account and not with a view towards, or for resale in connection with, the public sale or distribution of this
    26



Warrant or the Warrant Shares, except pursuant to sales registered or exempted under the Securities Act.
(ii) The Holder understands and acknowledges that this Warrant and the Warrant Shares to be issued upon exercise hereof are “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that, under such laws and applicable regulations, such securities may be resold without registration under the Securities Act only in certain limited circumstances. In addition, the Holder represents that it is familiar with Rule 144 under the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.
(iii) The Holder acknowledges that it can bear the economic and financial risk of its investment for an indefinite period, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Warrant and the Warrant Shares. The Holder has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Warrant and the business, properties, prospects and financial condition of the Company.
11.Warrant Register. The Company shall keep and properly maintain at its principal executive offices books for the registration of the Warrant and any transfers thereof. The Company may deem and treat the Person in whose name the Warrant is registered on such register as the Holder thereof for all purposes, and the Company shall not be affected by any notice to the contrary, except any assignment, division, combination or other transfer of the Warrant effected in accordance with the provisions of this Warrant.
12.Notices. All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been given:
(a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested); (c) on the date sent by facsimile or e-mail of a PDF document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next Business Day if sent after normal business hours of the recipient; or (d) on the third day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid. Such communications must be sent to the respective parties at the addresses indicated below (or at such other address for a party as shall be specified in a notice given in accordance with this Section 12).

Each of the Company and the Holder acknowledges that a breach or threatened breach by such party of any of its obligations under this Warrant would give rise to irreparable harm to the other party hereto for which monetary damages would not be an adequate remedy and hereby agrees that in the event of a breach or a threatened breach by such party of any such obligations, the other party hereto shall, in addition to any and all other rights and remedies that may be available to it in respect of such breach, be entitled to equitable relief, including a restraining order, an injunction, specific performance and any other relief that may be available from a court of competent jurisdiction.

    28



19.Amendment and Modification; Waiver. Except as otherwise provided herein, this Warrant may only be amended, modified or supplemented by an agreement in writing signed by each party hereto. No waiver by the Company or the Holder of any of the provisions hereof shall be effective unless explicitly set forth in writing and signed by the party so waiving.

No failure to exercise, or delay in exercising, any rights, remedy, power or privilege arising from this Warrant shall operate or be construed as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.
20.Severability. If any term or provision of this Warrant is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Warrant or invalidate or render unenforceable such term or provision in any other jurisdiction.
21.Governing Law. This Warrant shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the domestic substantive laws of any other jurisdiction.
22.Submission to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Warrant or the transactions contemplated hereby may be instituted in the courts located in New Castle County, Delaware, as well as to the jurisdiction of all courts to which an appeal may be taken from such courts, and each party irrevocably submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding. Service of process, summons, notice or other document by certified or registered mail to such party’s address set forth herein shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or any proceeding in such courts and irrevocably waive and agree not to plead or claim in any such court that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.
23.Waiver of Jury Trial. Each party acknowledges and agrees that any controversy which may arise under this Warrant is likely to involve complicated and difficult issues and, therefore, each such party irrevocably and unconditionally waives any right it may have to a trial by jury in respect of any legal action arising out of or relating to this Warrant or the transactions contemplated hereby.

Notwithstanding the foregoing, this Warrant shall become fully vested and shall be automatically exercised pursuant to Section 3(b)(ii) immediately prior to the consummation of a Change of Control.
3.Exercise of Warrant.
(a) Exercise Procedure. This Warrant may be exercised from time to time on any Business Day during the Exercise Period, for all or any part of the unexercised Warrant Shares into which it is then exercisable, upon:

Warrant in exchange for the number of Warrant Shares as is computed using the following formula:
X = Y(A-B) ÷ A

X = the number of Warrant Shares to be issued to the Holder;
Y = the total number of Warrant Shares for which the Holder has elected to exercise this Warrant pursuant to Section 3(a);
A = the Fair Market Value of one Warrant Share as of the applicable Exercise Date; and
B = the Exercise Price in effect under this Warrant as of the applicable Exercise Date.
In the event of any withholding of Warrant Shares to effect a net settlement pursuant to clause (ii) above where the number of shares issuable thereunder is not a whole number, the number of shares issued by the Company on a net basis shall be rounded down to the nearest whole share and the Company shall make a cash payment to the Holder (by delivery of a certified or official bank check or by wire transfer of immediately available funds) based on the incremental fraction of a share being so withheld by the Company in an amount equal to the product of (x) such incremental fraction of a share being so withheld multiplied by (y) the Fair Market Value per Warrant Share as of the Exercise Date.

As to any fraction of a Warrant Share that the Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay to such Holder an amount in cash (by delivery of a certified or official bank check or by wire transfer of immediately available funds) equal to the product of (i) such fraction multiplied by (ii) the Fair Market Value of one Warrant Share on the Exercise Date.
(d) Delivery of New Warrant. Unless the purchase rights represented by this Warrant shall have expired or shall have been fully exercised, the Company shall, at the time of delivery of the certificate or certificates representing the Warrant Shares being issued in accordance with Section 3 hereof, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unexpired and unexercised Warrant Shares called for by this Warrant. Such new Warrant shall in all other respects be identical to this Warrant.
(e) Valid Issuance of Warrant and Warrant Shares; Payment of Taxes. With respect to the exercise of this warrant, the Company hereby represents, covenants and agrees:
(i) This Warrant is, and any Warrant issued in substitution for or replacement of this Warrant shall be, upon issuance, duly authorized and validly issued.

(iii) The Company shall take all such actions as may be necessary to ensure that all such Warrant Shares are issued without violation by the Company of any applicable law or governmental regulation or any requirements of any primary securities exchange upon which Common Shares or other securities constituting Warrant Shares may be listed at the time of such exercise (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance).
(iv) The Company shall use reasonable commercial efforts to cause the Warrant Shares, immediately upon such exercise, to be listed on any primary securities exchange upon which Common Shares or other securities constituting Warrant Shares are listed at the time of such exercise.
(v) The Company shall pay all expenses in connection with, and all taxes and other governmental charges that may be imposed with respect to, the issuance or delivery of Warrant Shares upon exercise of this Warrant; provided, that the Company shall not be required to pay any tax or governmental charge that may be imposed with respect to any applicable withholding or the issuance or delivery of the Warrant Shares to any Person other than the Holder, and no such issuance or delivery shall be made unless and until the Person requesting such issuance has paid to the Company the amount of any such tax, or has established to the satisfaction of the Company that such tax has been paid.
(f) Conditional Exercise. Notwithstanding any other provision hereof, if an exercise of any portion of this Warrant is to be made in connection with a sale of the Company (pursuant to a merger, sale of stock, or otherwise), such exercise may at the election of the Holder be conditioned upon the consummation of such transaction, in which case such exercise shall not be deemed to be effective until immediately prior to the consummation of such transaction.
(g) Reservation of Shares.

4.Adjustment to Exercise Price and Number of Warrant Shares. The Exercise Price and the number of Warrant Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as provided in this Section 4 (in each case, after taking into consideration any prior adjustments pursuant to this Section 4).
(a) Adjustment to Exercise Price and Warrant Shares Upon Dividend, Subdivision or Combination of Common Shares. If the Company shall, at any time or from time to time after the Original Issue Date, (i) pay a dividend or make any other distribution upon the Common Shares or any other capital stock of the Company that is payable in Common Shares, or (ii) subdivide (by any stock split, recapitalization or otherwise) its outstanding Common Shares into a greater number of shares, the Exercise Price in effect

immediately prior to any such dividend, distribution or subdivision shall be proportionately reduced and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately increased. If the Company at any time combines (by combination, reverse stock split or otherwise) its outstanding Common Shares into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately decreased. Any adjustment under this Section 4(a) shall become effective at the close of business on the date the dividend, subdivision or combination becomes effective.
(b) Adjustment to Exercise Price and Warrant Shares Upon Reorganization, Reclassification, Consolidation or Merger. In the event of any (i) capital reorganization of the Company, (ii) reclassification of the stock of the Company (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares), (iii) consolidation or merger of the Company with or into another Person, (iv) sale of all or substantially all of the Company’s assets to another Person or (v) other similar transaction (other than any such transaction covered by Section 4(a) or any Change of Control, which shall be governed by Section 2), in each case which entitles the holders of Common Shares to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Shares, each Warrant shall, immediately after such reorganization, reclassification, consolidation, merger, sale or similar transaction, remain outstanding and shall thereafter, in lieu of or in addition to (as the case may be) the number of Warrant Shares then exercisable under this Warrant, be exercisable for the kind and number of shares of stock or other securities or assets of the Company or of the successor Person resulting from such transaction to which the Holder would have been entitled upon such reorganization, reclassification, consolidation, merger, sale or similar transaction if the Holder had exercised this Warrant in full immediately prior to the time of such reorganization, reclassification, consolidation, merger, sale or similar transaction and acquired the applicable number of Warrant Shares then issuable hereunder as a result of such exercise (without taking into account any limitations or restrictions on the exercisability of this Warrant); and, in such case, appropriate adjustment (in form and substance satisfactory to the Holder) shall be made with respect to the Holder’s rights under this Warrant to insure that the provisions of this Section 4 hereof shall thereafter be applicable, as nearly as possible, to this Warrant in relation to any shares of stock, securities or assets thereafter acquirable upon exercise of this Warrant (including, in the case of any consolidation, merger, sale or similar transaction in which the successor or purchasing Person is other than the Company, an immediate adjustment in the Exercise Price to the value per share for the Common Shares reflected by the terms of such consolidation, merger, sale or similar transaction, and a corresponding immediate adjustment to the number of Warrant Shares acquirable upon exercise of this Warrant without regard to any limitations or restrictions on exercise, if the value so reflected is less than the Exercise Price in effect immediately prior to such consolidation, merger, sale or similar transaction). The provisions of this Section 4(b) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales or similar transactions. The Company shall not effect any such reorganization, reclassification, consolidation, merger, sale or similar transaction unless, prior to the consummation thereof, the successor Person (if other than the

Notwithstanding anything to the contrary contained herein, with respect to any corporate event or other transaction contemplated by the provisions of this Section 4(b), the Holder shall have the right to elect prior to the consummation of such event or transaction, to give effect to the exercise rights contained in Section 2 instead of giving effect to the provisions contained in this Section 4(b) with respect to this Warrant.
(c) Certificate as to Adjustment.
(i) As promptly as reasonably practicable following any adjustment of the Exercise Price, but in any event not later than five (5) Business Days thereafter, the Company shall furnish to the Holder a certificate of an executive officer setting forth in reasonable detail such adjustment and the facts upon which it is based and certifying the calculation thereof. As promptly as reasonably practicable following the receipt by the Company of a written request by the Holder, but in any event not later than five (5) Business Days thereafter, the Company shall furnish to the Holder a certificate of an executive officer certifying the Exercise Price then in effect and the number of Warrant Shares or the amount, if any, of other shares of stock, securities or assets then issuable upon exercise of the Warrant.
6.Transfer of Warrant. Subject to the transfer conditions referred to in the legend endorsed hereon, this Warrant and all rights hereunder are transferable, in whole or in part, by the Holder without charge to the Holder, upon surrender of this Warrant to the Company at its then principal executive offices with a properly completed and duly executed Assignment in the form attached hereto as Exhibit B, together with funds sufficient to pay any transfer taxes described in Section 3(e)(v) in connection with the making of such transfer. Upon such compliance, surrender and delivery and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant, if any, not so assigned and this Warrant shall promptly be cancelled.
7.Holder Not Deemed a Shareholder; Limitations on Liability. Except as otherwise specifically provided herein and for common shares held directly by Holder not subject to this Warrant, prior to the issuance to the Holder of the Warrant Shares which the Holder is then entitled to receive upon the due exercise of this Warrant, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of shares of capital stock of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, as such, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of

Subject to compliance with the applicable provisions of this Warrant as to any transfer or assignment which may be involved in such division or combination, the Company shall at its own expense execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants so surrendered in accordance with such notice. Such new Warrant or Warrants shall be of like tenor to the surrendered Warrant or Warrants and shall be exercisable in the aggregate for an equivalent number of Warrant Shares as the Warrant or Warrants so surrendered in accordance with such notice.
9.No Impairment.

Warrant Shares to be issued upon exercise hereof except under circumstances that will not result in a violation of the Securities Act of 1933, as amended (the “Securities Act”). This Warrant and all Warrant Shares issued upon exercise of this Warrant (unless registered under the Securities Act) shall be stamped or imprinted with a legend in substantially the following form:
“THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR QUALIFIED UNDER ANY STATE OR FOREIGN SECURITIES LAWS AND MAY NOT BE OFFERED FOR SALE, SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED OR ASSIGNED UNLESS (I) A REGISTRATION STATEMENT COVERING SUCH SHARES IS EFFECTIVE UNDER THE ACT AND IS QUALIFIED UNDER APPLICABLE STATE AND FOREIGN LAW OR (II) THE TRANSACTION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS UNDER THE ACT AND THE QUALIFICATION REQUIREMENTS UNDER APPLICABLE STATE AND FOREIGN LAW AND, IF THE COMPANY REQUESTS, AN OPINION SATISFACTORY TO THE COMPANY TO SUCH EFFECT HAS BEEN RENDERED BY COUNSEL.”
Notwithstanding the forgoing, certificates evidencing the Warrant Shares shall not be required to contain such legend, (i) while a registration statement covering the resale of such Warrant Shares is effective under the Securities Act, (ii) following any sale of such Warrant Shares pursuant to Rule 144 (assuming cashless exercise of the Warrants), or (iii) if such Warrant Shares are eligible for sale under Rule 144 (assuming cashless exercise of the Warrants) (provided, however, that in the case of (i), (ii) and (iii), above, the holder provides the Company with customary legal representation letters reasonably acceptable to the Company). Whenever such restrictions shall cease and terminate as to any such Warrant Shares, the holder of such Warrant Shares shall be entitled to receive from the Company upon a written request in writing, without expense, new securities of like tenor not bearing the legend set forth herein. The Company shall cooperate with any holder of such Warrant Shares and, to the extent applicable, facilitate the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Warrant Shares and enable such certificates to be in such denominations or amounts, as the case may be, as the holder may reasonably request and registered in such names as such holder may request. Notwithstanding the forgoing, the Company’s obligations under this Section 10 with respect to Warrant Shares that may be sold under Rule 144 are contingent on the Company’s receipt from Holder of a customary Rule 144 representation letter in form and substance reasonably acceptable to the Company.
(b) Representations of the Holder. In connection with the issuance of this Warrant, the Holder specifically represents, as of the date hereof, to the Company by acceptance of this Warrant as follows:
(i) The Holder is an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act. The Holder is acquiring this Warrant and the Warrant Shares to be issued upon exercise hereof for investment for its own account and not with a view towards, or for resale in connection with, the public sale or distribution of this

Warrant or the Warrant Shares, except pursuant to sales registered or exempted under the Securities Act.
(ii) The Holder understands and acknowledges that this Warrant and the Warrant Shares to be issued upon exercise hereof are “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that, under such laws and applicable regulations, such securities may be resold without registration under the Securities Act only in certain limited circumstances. In addition, the Holder represents that it is familiar with Rule 144 under the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.
(iii) The Holder acknowledges that it can bear the economic and financial risk of its investment for an indefinite period, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Warrant and the Warrant Shares. The Holder has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Warrant and the business, properties, prospects and financial condition of the Company.
11.Warrant Register. The Company shall keep and properly maintain at its principal executive offices books for the registration of the Warrant and any transfers thereof. The Company may deem and treat the Person in whose name the Warrant is registered on such register as the Holder thereof for all purposes, and the Company shall not be affected by any notice to the contrary, except any assignment, division, combination or other transfer of the Warrant effected in accordance with the provisions of this Warrant.

Nature of the Business and Basis of Presentation 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. Biohaven is a biopharmaceutical company focused on the discovery, development and commercialization of life-changing treatments in key therapeutic areas, including immunology, neuroscience, and oncology. The Company is advancing its innovative portfolio of therapeutics, leveraging its proven drug development experience and multiple, proprietary drug development platforms. Biohaven's extensive clinical and preclinical programs include Kv7 ion channel modulation for epilepsy and mood disorders; extracellular protein degradation for immunological diseases; Transient Receptor Potential Melastatin 3 ("TRPM3") antagonism for migraine and neuropathic pain; Tyrosine Kinase 2/Janus Kinase 1 ("TYK2/JAK1") inhibition for neuroinflammatory disorders; glutamate modulation for obsessive compulsive disorder ("OCD") and spinocerebellar ataxia ("SCA"); myostatin inhibition for neuromuscular and metabolic diseases, including spinal muscular atrophy ("SMA") and obesity; and antibody recruiting bispecific molecules ("ARMs") and antibody drug conjugates ("ADCs") for cancer.
The Company is subject to risks and uncertainties common to 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.
Separation from Biohaven Pharmaceutical Holding Company Ltd.
On October 3, 2022, Biohaven Pharmaceutical Holding Company Ltd. (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 Ltd.
from the Former Parent (the “Spin-Off”) described in Biohaven’s Information Statement attached as Exhibit 99.1 to Biohaven’s Registration Statement on Form 10, as amended (Reg. No. 001-41477). Collectively, we refer to the Distribution and Spin-Off throughout this Quarterly Report on Form 10-Q as the "Separation." As a result of the Separation, Biohaven 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. Where we describe historical business activities in this report, we do so as if the Former Parent’s activities related to such assets and liabilities had been performed by the Company.
Basis of Presentation
The accompanying condensed consolidated 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 SEC. The accompanying condensed consolidated financial statements include the accounts of Biohaven Ltd. and our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
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 consolidated financial statements are issued.
Through August 9, 2024, the Company has funded its operations primarily with funding from the Former Parent, proceeds from the sale of its common shares, and the cash contribution received from the Former Parent at the Separation. The Company has incurred recurring losses since its inception and expects to continue to generate operating losses for the foreseeable future.
As of the date of issuance of these condensed consolidated financial statements, the Company expects its existing cash, cash equivalents, and marketable securities will be sufficient to fund operating and financial commitments, and other cash requirements for at least one year after the issuance date of these financial statements.
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.

Accounting Policies [Abstract]  
Summary of Significant Accounting Policies Summary of Significant Accounting Policies
Our significant accounting policies are described in Note 2, "Summary of Significant Accounting Policies" to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Form 10-K"). Updates to our accounting policies are discussed below in this Note 2.
Unaudited Interim Condensed Consolidated Financial Information
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information. The accompanying unaudited condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. The accompanying year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of June 30, 2024, the results of its operations for the three and six months ended June 30, 2024 and 2023, and its cash flows for the six months ended June 30, 2024 and 2023. The results for the three and six months ended June 30, 2024 are not necessarily indicative of results to be expected for
the year ending December 31, 2024, any other interim periods or any future year or period.  The financial information included herein should be read in conjunction with the financial statements and notes in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.
Reclassifications
Certain items in the prior period’s condensed consolidated financial statements have been reclassified to conform to the current year presentation.
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual for research and development expenses and valuation of forward contract and derivative liabilities. In addition, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.
Restricted Cash
Restricted cash included in other current assets in the condensed consolidated balance sheets consists primarily of employee contributions to the Company's employee share purchase plan held for future purchases of the Company's outstanding shares.
Restricted cash included in other non-current assets in the condensed consolidated balance sheets represents collateral held by banks for a letter of credit ("LOC") issued in connection with the leased office space in Yardley, Pennsylvania and LOCs issued in connection with the leased office and lab spaces in Cambridge, Massachusetts and Pittsburgh, Pennsylvania. See Note 11, ‘‘Commitments and Contingencies’’ for additional information on the real estate leases.
The following represents a reconciliation of cash and cash equivalents in the condensed consolidated balance sheets to total cash, cash equivalents and restricted cash as of June 30, 2024 and June 30, 2023, respectively, in the condensed consolidated statements of cash flows:
As of June 30, 2024As of June 30, 2023
Cash and cash equivalents$239,147 $147,612 
Restricted cash held on behalf of Former Parent— 40,415 
Restricted cash (included in other current assets)156 11,574 
Restricted cash (included in other non-current assets)3,015 2,349 
Total cash, cash equivalents and restricted cash at the end of the period in the condensed consolidated statement of cash flows$242,318 $201,950 
Forward Contracts and Derivative Liabilities
The Company evaluates certain of its financial and business development transactions to determine the accounting classification of equity linked instruments issued in those transactions. The Company first assesses whether a freestanding equity linked instrument meets liability classification in accordance with ASC 480-10 Distinguishing Liabilities from Equity and ASC 815-40 Derivatives and Hedging - Contracts in Entity's Own Equity. Under ASC 480-10 an instrument is considered liability classified if the instrument is mandatorily redeemable, obligate the issuer to settle an instrument or the underlying shares by paying cash or other assets, or must or may require settlement by issuing variable number of shares.
If an instrument does not meet liability classification under ASC 480-10, the Company assesses the requirements under ASC 815-40, which states that contracts that require or may require net cash settlement are liabilities recorded at fair value. If the instrument does not require liability classification under ASC 815-40, in order to conclude equity classification, the Company assesses whether the instrument is indexed to its common stock and whether the instrument is classified as equity under ASC 815-40 or other applicable GAAP.
Equity linked instruments that are accounted for in accordance with ASC 815-40 are reported as liabilities on the condensed consolidated balance sheets at fair
value. Any change in fair value, as determined at each measurement period, is recorded as a component of other income (expense), net on the condensed consolidated statements of operations and comprehensive loss. Changes in fair value are reported on the condensed consolidated statements of cash flows as change in fair value of forward contract and derivative liabilities.
The Company accounted for certain consideration agreed to in connection with the Amendment, dated as of May 1, 2024 (the "Knopp Amendment"), to the Membership Interest Purchase Agreement, dated as of February 24, 2022 (the "Purchase Agreement") entered into with Knopp Biosciences, LLC ("Knopp") as derivative liabilities under ASC 815 (see Notes 4, "Fair Value of Financial Assets and Liabilities" and 10, "License, Acquisitions and Other Agreements").
Warrants
The Company evaluates warrants issued as either equity instruments, liabilities or derivative liabilities in accordance with ASC Topic 480, Distinguishing Liabilities from Equity ("ASC 480") and/or ASC Topic 815, Derivatives and Hedging ("ASC 815"), depending on the specific terms of the warrant agreement.
The Company assessed the warrants issued to Knopp in May 2024 (the "Knopp Warrants") and concluded that they met the criteria for equity classification under ASC 480 and ASC 815. Accordingly, the Knopp Warrants were recorded within additional paid-in capital on the condensed consolidated balance sheet at the time of issuance and are not subject to remeasurement. See Note 6, Shareholders' Equity for further detail on the Knopp Warrants.
Fair Value Measurements
Certain assets and liabilities of the Company are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value
hierarchy, of which the first two are considered observable and the last is considered unobservable:
•Level 1—Quoted prices in active markets for identical assets or liabilities.
•Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.
•Level 3—Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.
The carrying values of other current assets, accounts payable, and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities.
The Company has accounted for certain consideration agreed to in connection with the Knopp Amendment as forward contract liabilities, which are recorded on the condensed consolidated balance sheets at fair value. Any changes in fair value, as determined each measurement period, are recorded as a component of other income (expense), net on the condensed consolidated statements of operations and comprehensive loss. The fair value of the forward contract liabilities is determined based on significant inputs not observable in the market, and therefore represents a Level 3 measurement within the fair value hierarchy. The valuations are based on a Monte Carlo simulation of the Company's share price, which requires judgement and assumption on the volatility of
Biohaven's share price, discounted to present value using a risk-free rate plus Biohaven specific credit risk since payable in a variable number of shares. (see Notes 4, "Fair Value of Financial Assets and Liabilities" and 10, "License, Acquisitions and Other Agreements").
Recently Issued Accounting Pronouncements
In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting—Improvements to Reportable Segment Disclosures, which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in ASU No. 2023-07 apply to public entities, including those with a single reportable segment, and are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact ASU No. 2023-07 will have on its consolidated financial statements
In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The ASU also includes certain other amendments to improve the effectiveness of income tax disclosures. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024, with early adoption permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is currently evaluating the impact ASU No. 2023-09 will have on its consolidated financial statements.

Fair Value Disclosures [Abstract]  
Fair Value of Financial Assets and Liabilities Fair Value of Financial Assets and Liabilities
The preparation of the Company’s condensed consolidated financial statements in accordance with GAAP requires certain assets and liabilities to be reflected at their fair value and others to be reflected on another basis, such as an adjusted historical cost basis. In this note, the Company provides details on the fair value of financial assets and liabilities and how it determines those fair values.
Financial Instruments Measured at Fair Value on the Condensed Consolidated Balance Sheets
Certain assets of the Company are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:
•Level 1 — Quoted prices in active markets for identical assets or liabilities.
•Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.
•Level 3 — Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.
Financial assets measured at fair value on a recurring basis on the condensed consolidated balance sheets at June 30, 2024 and December 31, 2023 and financial liabilities measured at fair value on a recurring basis on the condensed consolidated balance sheets at June 30, 2024 were as follows :

The Company had no financial liabilities measured at fair value on a recurring basis on the condensed consolidated balance sheets at December 31, 2023.
There were no securities transferred into or out of Level 3 during the three and six months ended June 30, 2024 or 2023.
The following is a description, including valuation methodology, of the financial assets measured at fair value on a recurring basis:
Cash Equivalents
Cash equivalents consisted of cash invested in short-term money market funds and debt securities with an original maturity of 90 days or less at the date of purchase. The carrying value of cash equivalents approximates fair value as maturities are less than three months. When quoted prices are available in an active market, cash equivalents are classified in Level 1 of the fair value hierarchy. Fair values of cash equivalent instruments that do not trade on a regular basis in active markets are classified as Level 2.
Marketable Securities and Other Non-Current Assets
Quoted prices for identical assets in active markets are considered Level 1 and consist of on-the-run U.S. Treasuries and money market funds. The fair values of the Company’s Level 2 debt securities are obtained from quoted market prices of debt securities with similar characteristics, quoted prices from identical assets in inactive markets, or discounted cash flows to estimate fair value.
Forward Contract and Derivative Liabilities
In connection with the Knopp Amendment, Knopp has the option to request a one-time cash true-up payment from the Company in December 2024, as defined in the agreement (the "2024 Additional Consideration True-up"). The Company also agreed to issue to Knopp additional common shares of the Company with an approximate value of $75,000 within 60 days of the first anniversary of execution of the Knopp Amendment (the “2025 Additional Consideration”). In addition, Knopp has the option to request a one-time cash true-up payment from the Company in December 2025, as defined in the agreement (the "2025 Additional Consideration True-up"). See Note 10, "License, Acquisitions and Other Agreements," for further details.
The following table provides a roll forward of the fair value of the Company's forward contract and derivative liabilities related to the Knopp Amendment for which fair value is determined by Level 3 inputs for the three months ended June 30, 2024:
Carrying Value
Fair value at May 1, 2024
$93,290 
Change in fair value of derivative in other income (expense), net
110 
Fair value at June 30, 2024
$93,400 
The fair value of the forward contract and derivative liabilities recognized in connection with the Knopp Amendment were determined based on significant inputs not observable in the market, and therefore represents a Level 3 measurement within the fair value hierarchy. The valuation is based on a Monte Carlo simulation of Biohaven's share price, which requires judgement and assumption on the volatility of Biohaven's share price, discounted to present value using a risk-free rate plus Biohaven specific credit risk since payable in a variable number of shares for the 2025 Additional Consideration or potentially cash for the 2024 Additional Consideration True-up and 2025 Additional Consideration True-up. A summary of the unobservable inputs (Level 3 inputs) used in measuring the Company’s forward contract and derivative liabilities related to the Knopp Amendment as of June 30, 2024 and May 1, 2024 are as follows, presented on a weighted-average basis:
As of June 30, 2024
As of May 1, 2024
Time to payment and potential payment (years)
0.911.08
Volatility (annual)
70.0 %80.0 %
Discount rate
15.6 %14.8 %
Our expectations of the volatility of Biohaven's share price at the reporting date could be materially different than our actual future volatility, and if so, would mean the estimated fair value could be significantly higher or lower than the fair value determined. The Company expects the fair value of the forward contract to be approximately $75,000 on the first anniversary of the Knopp Amendment. An increase in the derivative liabilities related to the 2024 Additional Consideration True-up and 2025 Additional Consideration True-up between the reporting date and settlement date of the derivatives would have a material adverse effect on the Company's financial performance.

Share-Based Payment Arrangement [Abstract]  
Non-Cash Share-Based Compensation Non-Cash Share-Based Compensation
Non-Cash Share-based Compensation Expense
The Company measures non-cash share-based compensation at the grant date based on the fair value of the award and recognizes non-cash shared-based compensation as expense over the requisite service period of the award (generally three years) using the straight-line method. Non-cash share-based compensation expense, consisting of expense for share options, restricted share units ("RSUs"), performance share options, and the Employee Share Purchase Plan ("ESPP"), was classified in the condensed consolidated statements of operations and comprehensive loss as follows:

Total non-cash share-based compensation expense$12,232 $4,695 $47,109 $8,460 
Share Options
All share option grants are awarded at fair value on the date of grant. The fair value of share options is estimated using the Black-Scholes option pricing model. Stock options generally expire 10 years after the grant date.
The aggregate intrinsic value of share options is calculated as the difference between the exercise price of the share options and the fair value of the Company's common shares for those share options that had exercise prices lower than the fair value of the Company's common shares at June 30, 2024.
As of June 30, 2024, total unrecognized compensation cost related to the unvested share options was $90,206, which is expected to be recognized over a weighted average period of 2.33 years, which does not consider the impact of a change in control. The weighted average grant date fair value per share of share options granted under the Company's share option plan during the six months ended June 30, 2024 and 2023 was $30.76 and $10.16, respectively. The Company expects
approximately 7,978,678 of the unvested stock options to vest over the requisite service period.

Restricted Share Units
The Company’s RSUs are considered nonvested share awards and require no payment from the employee. For each RSU, employees receive one common share at the end of the vesting period. The employee can elect to receive the one common share net of taxes or pay for taxes separately and receive the entire share. Compensation cost is recorded based on the market price of the Company’s common shares on the grant date and is recognized on a straight-line basis over the requisite service period.
As of June 30, 2024, there was $9,405 of total unrecognized compensation cost related to Company RSUs that are expected to vest. These costs are expected to be recognized over a weighted-average period of 2.53 years, which does not consider the impact of a change in control. The total fair value of RSUs vested during the three and six months ended June 30, 2024 was $3,770.

The Company has not recorded these potential contingent consideration payments as liabilities in the accompanying condensed consolidated balance sheet as none of the future events which would trigger a milestone payment were considered probable of occurring at June 30, 2024.
Yale Agreements
In September 2013, the Company entered into an exclusive license agreement (the "Yale Agreement") with Yale University to obtain a license to certain patent rights for the commercial development, manufacture, distribution, use and sale of products and processes resulting from the development of those patent rights, related to the use of riluzole in treating various neurological conditions, such as general anxiety disorder, post-traumatic stress disorder and depression.
The Yale Agreement was amended and restated in May 2019. As of June 30, 2024, under the amended Yale Agreement, the Company has remaining contingent regulatory approval milestone payments of up to $2,000 and annual royalty payments of a low single-digit percentage based on net sales of riluzole-based products from the licensed patents or from products based on troriluzole. Under the amended and restated agreement, the royalty rates are reduced as compared to the original agreement. In addition, under the amended and restated agreement, the Company may develop products based on riluzole or troriluzole. The amended and restated agreement retains a minimum annual royalty of up to $1,000 per year, beginning after the first sale of product under the agreement. If the Company grants any sublicense rights under the Yale Agreement, it must pay Yale University a low single-digit percentage of sublicense income that it receives.
For the three and six months ended June 30, 2024 and 2023, the Company did not record any material milestone or royalty payments under the Yale Agreement.
In January 2021, the Company entered into a worldwide, exclusive license agreement with Yale
University for the development and commercialization of a novel Molecular Degrader of Extracellular Protein ("MoDE") platform (the "Yale MoDE Agreement").

The Yale MoDE Agreement includes an obligation to pay a minimum annual royalty of up to $1,000 per year, and low single digit royalties on the net sales of licensed products. If the Company grants any sublicense rights under the Yale MoDE Agreement, it must pay Yale University a low single-digit percentage of sublicense income that it receives. As of June 30, 2024, under the Yale MoDE Agreement, the Company has remaining contingent development and commercial milestone payments of up to $650 and $2,950, respectively. The Yale MoDE Agreement terminates on the later of twenty years from the effective date, twenty years from the filing date of the first investigational new drug application for a licensed product or the last to expire of a licensed patent.
The Company did not record any material milestone or royalty payments under the Yale MoDE Agreement for the three months ended June 30, 2024. For the six months ended June 30, 2024, the Company recorded research and development expense of $150 related to the achievement of a developmental milestone under the Yale MoDE Agreement.

Under the ALS Biopharma Agreement, the Company is obligated to use commercially reasonable efforts to commercialize and develop markets for the patent products. As of June 30, 2024, under the ALS Biopharma Agreement, the Company has remaining contingent regulatory approval milestone payments of up to $4,000, as well as royalty payments of a low single-digit percentage based on net sales of products licensed under the ALS Biopharma Agreement, payable on a quarterly basis.
The ALS Biopharma Agreement terminates on a country-by-country basis as the last patent rights expire
in each such country. If the Company abandons its development, research, licensing or sale of all products covered by one or more claims of any patent or patent application assigned under the ALS Biopharma Agreement, or if the Company ceases operations, it has agreed to reassign the applicable patent rights back to ALS Biopharma.
For the three and six months ended June 30, 2024 and 2023, the Company did not record any material milestone or royalty payments under the ALS Biopharma Agreement.
Taldefgrobep Alfa License Agreement

Agreement with Hangzhou Highlightll Pharmaceutical Co. Ltd.
In March 2023, the Company and Hangzhou Highlightll Pharmaceutical Co. Ltd. ("Highlightll") entered into an exclusive, worldwide (excluding People’s Republic of China and its territories and possessions) license agreement (the "Highlightll Agreement") pursuant to which Biohaven obtained the right to research, develop, manufacture and commercialize Highlightll’s brain penetrant dual TYK2/JAK1 inhibitor program. In connection with the Highlightll Agreement, the Company was obligated to pay Highlightll a cash payment of $10,000 and 721,136 common shares (collectively, "the Highlightll Upfront Payments"), upon the completion of certain post-closing activities. In December 2023, the Company entered into a second amendment to the Highlightll Agreement, which granted the Company an exclusive option and right of first refusal to any Selective TYK2 Inhibitor being developed
by or on behalf of Highlightll or its affiliates and provided for the payment of the Highlightll Upfront Payments. As a result, the Company made a $10,000 cash payment and issued 721,136 shares, valued at $21,814 to Highlightll during the fourth quarter of 2023, which was recorded as R&D expense during the fourth quarter of 2023.
As of June 30, 2024, under the Highlightll Agreement, the Company has remaining contingent development, regulatory approval, and commercial milestone payments of up to $75,000, $37,500, and $837,500, respectively. Additionally, the Company has agreed to make tiered royalty payments as a percentage of net sales starting at mid single digits and peaking at low teens digits. During the royalty term, if the Company offers to include China clinical sites in its Phase 3 study sufficient for submission to Chinese National Medical Products Administration and Highlightll, at its sole discretion, agrees, then Highlightll will pay royalties in the low tens digits to the Company on China sales upon approval.
The Highlightll Agreement terminates on a country-by-country basis upon expiration of the royalty term and can also be terminated if certain events occur, e.g., material breach or insolvency.
For the three and six months ended June 30, 2024 and 2023, the Company did not record any material milestone or royalty payments related to the Highlightll Agreement.
Other Agreements
In addition to the agreements detailed above, the Company has entered into various other license agreements and development programs. The Company records milestones and other payments, including funding for research arrangements, which become due under these agreements to research and development expense in the condensed consolidated statements of operations and comprehensive loss. Amounts recorded for the period were as follows:

Acquisitions
Kv7 Platform Acquisition
In April 2022, the Company closed the acquisition from Knopp of Channel Biosciences, LLC (“Channel”), a wholly owned subsidiary of Knopp owning the assets of Knopp’s Kv7 channel targeting platform (the “Kv7 Platform Acquisition”), pursuant to the Purchase Agreement, dated February 24, 2022.
Under the Purchase Agreement, the Company agreed to make success-based payments based on developmental and regulatory milestones through approvals in the United States, Europe, the Middle East and Asia ("EMEA") and Japan for the lead asset, BHV-7000 (formerly known as KB-3061), developmental and regulatory milestones for the Kv7 pipeline development in other indications and additional country approvals, and commercial sales-based milestones of BHV-7000. Additionally, the Company agreed to make scaled royalty payments in cash for BHV-7000 and the pipeline programs, with percentages starting at high single digits and peaking at low teens for BHV-7000 and starting at mid-single digits and peaking at low tens digits for the pipeline programs.
In May 2024, the Company entered into the Knopp Amendment under which the parties thereto agreed to replace the scaled high single digit to low teens royalty payment obligations with a flat royalty payment in the mid-single digits for BHV-7000 and the pipeline programs. The parties also agreed to reduce the success-based payments payable under the Purchase Agreement. The Company retains the ability to pay these contingent milestone payments in cash or in the Company's common shares at Biohaven's election, subject to the same increases if the Company elects to pay in the Company's common shares. As of June 30, 2024, under the Purchase Agreement, as amended, the Company had remaining success-based payments comprised of (i) to up to $185,000 based on regulatory approvals in the United States and EMEA for BHV-7000 and (ii) up to an additional $60,000 based on regulatory approval in the United States for the other Kv7 pipeline programs.
In consideration of the revisions to the success-based payment and royalty payment obligations, the Company agreed to issue to Knopp 1,872,874 Company common shares, valued at approximately $75,000, through a private placement within 60 days of the date of execution of the Knopp Amendment (the “2024 Additional Consideration”) and additional Company common shares with an approximate value of $75,000 within 60 days of the first anniversary of execution of the
Knopp Amendment (the “2025 Additional Consideration”). The Company has also given Knopp the option to request a one-time cash true-up payment from the Company in December 2024 in the event that Knopp continues to hold the Company's common shares representing the 2024 Additional Consideration and the value of such shares has declined (the "2024 Knopp True-Up"), and a one-time cash true-up payment from the Company in December 2025 in the event that Knopp continues to hold the Company's common shares representing the 2025 Additional Consideration and the value of such shares has declined (the "2025 Knopp True-Up"), in each case, subject to certain conditions.
The Company concluded that the agreement to issue the 2024 Additional Consideration at a future date represented a fixed forward contract under ASC 815 and classified the commitment as a forward contract liability on its condensed consolidated balance sheet on the execution date of the Knopp Amendment. The Company initially measured the forward contract associated with the 2024 Additional Consideration at a fair value of $75,220, which was recorded as R&D expense during the three months ended June 30, 2024 in its condensed consolidated statements of operations and comprehensive loss. In May 2024, the Company issued the 2024 Additional Consideration at an approximate value of $65,981 and recognized a $9,239 gain upon settlement of the forward contract in other income (expense), net in its condensed consolidated statement of operations and comprehensive loss during the three months ended June 30, 2024. The gain on settlement of the 2024 Additional Consideration is due to the decline in fair value of the 2024 Additional Consideration from the execution date to the issuance date due to a decline in Biohaven's share price. Refer to Note 4, "Fair Value of Financial Assets and Liabilities" and Note 6, "Shareholders' Equity" for further discussion.
The 2024 Additional Consideration True-up represents a net cash settled written put option measured at fair value on a recurring basis. The Company has concluded that the 2024 Additional Consideration True-up represents a net cash settled written put option on the Company’s shares and is a freestanding derivative liability under ASC 815. Accordingly, the Company classified the 2024 Additional Consideration True-up as a current derivative liability on its condensed consolidated balance sheet. The Company initially recorded the 2024 Additional Consideration True-up at a fair value of $15,540, which was recorded as R&D expense during the three months ended June 30, 2024 in its condensed consolidated statements of operations and comprehensive loss. The Company subsequently remeasures the fair value of the derivative
liability and recognizes any gains or losses through other income (expense), net in its condensed consolidated statement of operations and comprehensive loss. The Company recognized expense of $590 for the three months ended June 30, 2024, related to the 2024 Additional Consideration True-up. Refer to Note 4, "Fair Value of Financial Assets and Liabilities" for further discussion.
The Company has concluded that the agreement to issue the 2025 Additional Consideration at a future date represents a forward contract settleable in a variable number of shares under ASC 480, and classified the commitment as a current forward contract liability on its condensed consolidated balance sheet. The Company initially measured the 2025 Additional Consideration at a fair value of $63,940, which was recorded as R&D expense during the three months ended June 30, 2024 in its condensed consolidated statements of operations and comprehensive loss. The Company subsequently remeasures the fair value of the forward contract liability and recognizes any gains or losses through other income (expense), net in its condensed consolidated statement of operations and comprehensive loss. The Company recognized expense of $1,150 for the three months ended June 30, 2024, related to the 2025 Additional Consideration. Refer to Note 4, "Fair Value of Financial Assets and Liabilities" for further discussion.
The Company has concluded that the 2025 Additional Consideration True-up represents a net cash settled written put option on the Company’s shares and is a freestanding derivative liability under ASC 815. Accordingly, the Company classified the 2025 Additional Consideration True-up as a non-current derivative liability on its condensed consolidated balance sheet. The Company initially recorded the 2025 Additional Consideration True-up at a fair value of $13,810, which was recorded as R&D expense during the three months ended June 30, 2024. The Company subsequently remeasures the fair value of the derivative liability and recognizes any gains or losses through other income (expense), net in its condensed consolidated statement of operations and comprehensive loss. The Company recognized a gain of $1,630 for the three months ended June 30, 2024, related to the 2025 Additional Consideration True-up. Refer to Note 4, "Fair Value of Financial Assets and Liabilities" for further discussion.
As further consideration for the revisions to the success-based payment and royalty payment obligations in the Knopp Amendment, the Company issued to Knopp a warrant (the “Warrant”) to purchase 294,195 Company common shares at a purchase price per share of $67.98,
subject to certain specified development milestones and the Company achieving a specified market capitalization. Refer to Note 6, "Shareholders' Equity" for further discussion.
The Company has not recorded any of the remaining contingent consideration payments to Knopp as a liability in the accompanying condensed consolidated balance sheet as none of the future events which would trigger a milestone payment were considered probable of occurring at June 30, 2024.
Pyramid Acquisition
In January 2024, the Company acquired Pyramid Biosciences, Inc. (“Pyramid”), pursuant to an Agreement and Plan of Merger, dated January 7, 2024 ("the Pyramid Agreement"). In consideration for the Pyramid acquisition, Biohaven made an upfront payment of 255,794 Company common shares, valued at approximately $10,894.
The Company accounted for this purchase as an asset acquisition as substantially all of the fair value of the gross assets acquired was concentrated in a single identifiable asset, IPR&D. The IPR&D asset has no alternative future use and relates primarily to BHV-1510. There was no material value assigned to any other assets or liabilities acquired in the acquisition. As such, the upfront payment discussed above was recorded as a charge to R&D expense in the accompanying condensed consolidated statements of operations and comprehensive loss during the three months ended March 31, 2024.
As of June 30, 2024, under the Pyramid Agreement, the Company has remaining success-based payments comprised of (i) up to $5,000 based on developmental and regulatory milestones for the lead asset, BHV-1510 (formerly known as PBI-410), (ii) up to an additional $30,000 based on developmental and regulatory milestones for a second asset (formerly known as PBI-200) and (iii) up to $40,000 for commercial sales-based milestones of BHV-1510. Contingent developmental and regulatory milestone payments may be paid in cash or Biohaven common shares at the election of Biohaven and commercial sales-based milestones are to be made in cash.
The Company has not recorded any of the remaining contingent consideration payments as a liability in the accompanying condensed consolidated balance sheet as none of the future events which would trigger a milestone payment were considered probable of occurring at June 30, 2024.
During the first quarter of 2024, the Company recorded $5,689 of R&D expense in the condensed consolidated statement of operations and comprehensive loss for a developmental milestone which became due under the Pyramid Agreement, to be paid in 98,129 common shares of the Company. See Note 6, "Shareholders' Equity" for discussion of common shares issued to as part of the Pyramid Agreement.

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies Commitments and Contingencies
Lease Agreements
The Company leases certain office and laboratory space. Other than the Pittsburgh Centre Avenue Lease described below, there have been no material changes to the lease obligations from those disclosed in Note 11, "Commitments and Contingencies" to the consolidated financial statements included in the 2023 Form 10-K.
Pittsburgh Centre Avenue Lease Agreement
In March 2024, the Company entered into a lease agreement in Pittsburgh, Pennsylvania for lab space (the "Pittsburgh Centre Avenue Lease"), which will be used to support the research and development of the Company's ion channel platform and replace the Company's current operating lease in Pittsburgh. The lease is expected to commence in mid 2025 after substantial completion of building improvements, and has a term of 122 months, with an option to extend for one additional period of 60 months. The Company expects to record the Pittsburgh Centre Avenue Lease as an operating lease. The Company has annual commitments relating to the Pittsburgh Centre Avenue Lease ranging from $1,859 to $2,373, excluding any additional tenant improvement allowance that would increase the base rent.
Research Commitments
The Company has agreements with several contract manufacturing organizations ("CMOs") and contract research organizations ("CROs") to provide products and services in connection with the Company’s preclinical studies and clinical trials. As of June 30, 2024, the Company had no remaining maximum research commitments in excess of one year.
Indemnification Agreements
In the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by
third parties. In addition, the Company has entered into indemnification agreements with members of its board of directors and executive officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many cases, unlimited. The Company’s amended and restated memorandum and articles of association also provide for indemnification of directors and officers in specific circumstances. To date, the Company has not incurred any material costs as a result of such indemnification provisions. The Company does not believe that the outcome of any claims under indemnification arrangements will have a material effect on its financial position, results of operations or cash flows, and it has not accrued any liabilities related to such obligations in its condensed consolidated financial statements as of June 30, 2024 or December 31, 2023.
License, Acquisition and Other Agreements
The Company has entered into licensing, developmental and acquisition agreements with various parties under which it is obligated to make contingent and non-contingent payments (see Note 10, "License, Acquisitions and Other Agreements").
Other Agreements
Moda Agreement
On January 1, 2021, the Company entered into a consulting services agreement (the "Moda Agreement") with Moda Pharmaceuticals LLC ("Moda") to further the scientific advancement of technology, drug discovery platforms (including the technology licensed under the Yale MoDE Agreement), product candidates and related intellectual property owned or controlled by the Company.
Under the Moda Agreement, the Company paid Moda an upfront cash payment of $2,700 and 37,836 shares of the Former Parent valued at approximately $3,243. In addition, Moda will be eligible to receive additional development and regulatory milestone payments of up to $81,612 and commercial milestone payments of up to $30,171. The Moda Agreement has a term of four years and may be terminated earlier by the Company or Moda under certain circumstances including, for example, the Company's discontinuation of research on the MoDE platform or default. In August 2023, the Company entered into an amendment to the Moda Agreement with Moda. Under the amendment, Moda will be eligible to receive development and
regulatory milestone payments up to $25,200 and commercial milestone payments up to $23,000, in addition to the milestones noted above.
The Company did not record any material milestone payments related to the Moda Agreement for the three months ended June 30, 2024. For the six months ended June 30, 2024, the Company recorded research and development expense of $850 related to developmental milestones under the Moda Agreement. For the three and six months ended June 30, 2023, the Company did not record any material milestone payments related to the Moda Agreement.
Legal Proceedings

The decrease in income tax provisions for the three and six months ended June 30, 2024 as compared to the same periods in 2023 was primarily attributable to the Company adopting the guidance contained in a Notice of Proposed Rule Making issued during the third quarter of 2023 by the United States Internal Revenue Service ("the Notice"). The Notice allows the Company to immediately deduct certain R&D expenditures which were incurred in the US and reimbursed by the Company’s foreign parent. Previously, these expenditures were required to be capitalized under the Tax Cuts and Jobs Act, which was effective for tax years beginning on or after January 1, 2022.

Unaudited Interim Condensed Consolidated Financial Information
Unaudited Interim Condensed Consolidated Financial Information
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information. The accompanying unaudited condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. The accompanying year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of June 30, 2024, the results of its operations for the three and six months ended June 30, 2024 and 2023, and its cash flows for the six months ended June 30, 2024 and 2023. The results for the three and six months ended June 30, 2024 are not necessarily indicative of results to be expected for
the year ending December 31, 2024, any other interim periods or any future year or period.  The financial information included herein should be read in conjunction with the financial statements and notes in the Company's Annual Report on Form 10-K for the year ended December 31, 2023
Reclassifications
Reclassifications
Certain items in the prior period’s condensed consolidated financial statements have been reclassified to conform to the current year presentation.
Use of Estimates
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual for research and development expenses and valuation of forward contract and derivative liabilities. In addition, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.
Restricted Cash
Restricted Cash
Restricted cash included in other current assets in the condensed consolidated balance sheets consists primarily of employee contributions to the Company's employee share purchase plan held for future purchases of the Company's outstanding shares.
Restricted cash included in other non-current assets in the condensed consolidated balance sheets represents collateral held by banks for a letter of credit ("LOC") issued in connection with the leased office space in Yardley, Pennsylvania and LOCs issued in connection with the leased office and lab spaces in Cambridge, Massachusetts and Pittsburgh, Pennsylvania. See Note 11, ‘‘Commitments and Contingencies’’ for additional information on the real estate leases.
Forward Contracts and Derivative Liabilities
Forward Contracts and Derivative Liabilities
The Company evaluates certain of its financial and business development transactions to determine the accounting classification of equity linked instruments issued in those transactions. The Company first assesses whether a freestanding equity linked instrument meets liability classification in accordance with ASC 480-10 Distinguishing Liabilities from Equity and ASC 815-40 Derivatives and Hedging - Contracts in Entity's Own Equity. Under ASC 480-10 an instrument is considered liability classified if the instrument is mandatorily redeemable, obligate the issuer to settle an instrument or the underlying shares by paying cash or other assets, or must or may require settlement by issuing variable number of shares.
If an instrument does not meet liability classification under ASC 480-10, the Company assesses the requirements under ASC 815-40, which states that contracts that require or may require net cash settlement are liabilities recorded at fair value. If the instrument does not require liability classification under ASC 815-40, in order to conclude equity classification, the Company assesses whether the instrument is indexed to its common stock and whether the instrument is classified as equity under ASC 815-40 or other applicable GAAP.
Equity linked instruments that are accounted for in accordance with ASC 815-40 are reported as liabilities on the condensed consolidated balance sheets at fair
value. Any change in fair value, as determined at each measurement period, is recorded as a component of other income (expense), net on the condensed consolidated statements of operations and comprehensive loss. Changes in fair value are reported on the condensed consolidated statements of cash flows as change in fair value of forward contract and derivative liabilities.
The Company accounted for certain consideration agreed to in connection with the Amendment, dated as of May 1, 2024 (the "Knopp Amendment"), to the Membership Interest Purchase Agreement, dated as of February 24, 2022 (the "Purchase Agreement") entered into with Knopp Biosciences, LLC ("Knopp") as derivative liabilities under ASC 815 (see Notes 4, "Fair Value of Financial Assets and Liabilities" and 10, "License, Acquisitions and Other Agreements")
Warrants
Warrants
The Company evaluates warrants issued as either equity instruments, liabilities or derivative liabilities in accordance with ASC Topic 480, Distinguishing Liabilities from Equity ("ASC 480") and/or ASC Topic 815, Derivatives and Hedging ("ASC 815"), depending on the specific terms of the warrant agreement.
The Company assessed the warrants issued to Knopp in May 2024 (the "Knopp Warrants") and concluded that they met the criteria for equity classification under ASC 480 and ASC 815. Accordingly, the Knopp Warrants were recorded within additional paid-in capital on the condensed consolidated balance sheet at the time of issuance and are not subject to remeasurement. See Note 6, Shareholders' Equity for further detail on the Knopp Warrants.
Fair Value Measurements
Fair Value Measurements
Certain assets and liabilities of the Company are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value
hierarchy, of which the first two are considered observable and the last is considered unobservable:
•Level 1—Quoted prices in active markets for identical assets or liabilities.
•Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.
•Level 3—Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.
The carrying values of other current assets, accounts payable, and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities.
The Company has accounted for certain consideration agreed to in connection with the Knopp Amendment as forward contract liabilities, which are recorded on the condensed consolidated balance sheets at fair value. Any changes in fair value, as determined each measurement period, are recorded as a component of other income (expense), net on the condensed consolidated statements of operations and comprehensive loss. The fair value of the forward contract liabilities is determined based on significant inputs not observable in the market, and therefore represents a Level 3 measurement within the fair value hierarchy. The valuations are based on a Monte Carlo simulation of the Company's share price, which requires judgement and assumption on the volatility of
Biohaven's share price, discounted to present value using a risk-free rate plus Biohaven specific credit risk since payable in a variable number of shares. (see Notes 4, "Fair Value of Financial Assets and Liabilities" and 10, "License, Acquisitions and Other Agreements").
