Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 11—Commitments and Contingencies (A) Commitments The Company has entered into commitments under various asset acquisition and license agreements. Additionally, the Company enters into agreements with contract service providers to assist in the performance of its research and development activities. Expenditures to contract research organizations and contract manufacturing organizations represent significant costs in the clinical development of its product candidates. Subject to required notice periods and certain obligations under binding purchase orders, the Company can elect to discontinue the work under these agreements at any time. The Company expects to enter into additional collaborative research, contract research, manufacturing, and supplier agreements in the future, which may require upfront payments and long-term commitments of capital resources. The Company also has commitments relating to its long-term debt and leases. Refer to Note 7, “Long-Term Debt” for further information. There have been no material changes to the commitments relating to the Company’s leases during the nine months ended December 31, 2023 outside the ordinary course of business. For further information regarding the Company’s lease commitments, refer to Note 15, “Leases” in the Company’s Annual Report on Form 10-K for the year ended March 31, 2023. Purchase Commitments In conjunction with Dermavant’s entry into the GSK Agreement in 2018, Dermavant entered into a clinical supply agreement pursuant to which GSK would provide a supply of tapinarof and clinical product at an agreed upon price during the Company’s clinical trials. In April 2019, Dermavant entered into a commercial supply agreement with GSK to continue to provide certain quantities of tapinarof and commercial product at agreed upon minimum quantities and price. The commercial supply agreement commenced in April 2022 upon completion of certain quality and regulatory conditions. In July 2022, Dermavant and GSK amended the terms of the clinical supply and commercial supply agreements which released GSK of certain commitments to supply tapinarof and released Dermavant of certain commitments to purchase tapinarof in exchange for a supplementary fee. Other supply and purchase commitments under the agreements remain in effect. In addition, Dermavant and Thermo Fisher Scientific (“TFS”) entered into a Commercial Manufacturing and Supply Agreement for which TFS agreed to provide a supply of tapinarof to Dermavant at an agreed upon price. The agreements discussed above require Dermavant to purchase certain quantities of inventory over a period of five years. As of December 31, 2023, the remaining minimum purchase commitment related to these agreements was estimated to be approximately $43.1 million. In November 2021, the Company’s subsidiary, Immunovant, entered into a Product Service Agreement (“PSA”) with Samsung Biologics Co., Ltd. (“Samsung”) by which Samsung will manufacture and supply Immunovant with batoclimab drug substance for commercial sale and perform other manufacturing-related services with respect to batoclimab. As of December 31, 2023, the remaining minimum purchase commitment related to this agreement was estimated to be approximately $18.3 million. Immunovant had the right to terminate the PSA with 30 days’ written notice to Samsung, exercisable no later than January 2024, in the event Immunovant decided to stop all development of, and all attempts to obtain regulatory approval for, batoclimab; subject to payment to Samsung of non-cancellable service fees and costs incurred by Samsung for all batches of batoclimab scheduled to be manufactured during the two-year period following such termination. Because efforts to develop and obtain regulatory approval for batoclimab remain ongoing, Immunovant did not exercise that early termination right and it has lapsed. As a result, Immunovant has an additional minimum obligation to Samsung of approximately $28.0 million to purchase additional batches of batoclimab in the four-year period of 2026 through 2029. In May 2021, the Company entered into a master subscription agreement with Palantir Technologies Inc. (“Palantir”) for access to Palantir’s proprietary software for a five-year period. As of December 31, 2023, the remaining minimum payments for this software subscription were $19.1 million. Cash Bonus Program In December 2023, the Company approved a special one-time cash retention bonus award to its employees in the aggregate amount of $76.9 million (the “Cash Bonus Program”). During the three and nine months ended December 31, 2023, the Company recognized selling, general and administrative expense and research and development expense of $27.2 million and $8.1 million, respectively, representing the portion of the bonus award that was vested and payable immediately. The remaining portion will be recognized over the applicable service period of the award. In February 2024, the Company expanded this Cash Bonus Program to include an award to its Chief Financial Officer on similar terms as the other awards previously made to other employees. The Chief Financial Officer did not receive a payment from the Cash Bonus Program approved in December. This award to the Chief Financial Officer was in the aggregate amount of $2.8 million. Fifty percent of the bonus will be payable within 30 days of the grant date, with the balance subject to vesting tied to the employee’s continued service to the Company, as described in more detail in Part II, Item 5 of this Quarterly Report. (B) Loss Contingencies The Company may be, from time to time, a party to various disputes and claims arising from normal business activities. The Company accrues for loss contingencies when available information indicates that it is probable that a liability has been incurred and the amount of such loss can be reasonably estimated, and if the Company believes that a reasonably possible loss exists, the Company discloses the facts and circumstances of the litigation or claim, including an estimable range, if possible. Immunovant Securities Litigation In February 2021, a putative securities class action complaint was filed against Immunovant and certain of its current and former officers in the U.S. District Court for the Eastern District of New York on behalf of a class consisting of those who acquired Immunovant’s securities from October 2, 2019 and February 1, 2021. The complaint alleged that Immunovant and certain of its officers violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, by making false and misleading statements regarding the safety of batoclimab and sought unspecified monetary damages on behalf of the putative class and an award of costs and expenses, including reasonable attorneys’ fees. In December 2021, the U.S. District Court appointed a lead plaintiff. In March 2022, the lead plaintiff filed an amended complaint adding both (i) the Company and (ii) Immunovant’s directors and underwriters as defendants, and asserting additional claims under Section 11, 12(a)(2), and 15 of the Securities Act of 1933, as amended, on behalf of a putative class consisting of those who purchased or otherwise acquired Immunovant’s securities pursuant and/or traceable to Immunovant’s follow-on public offering on or about September 2, 2020. In February 2023, after further briefing on the amended complaint the U.S. District Court issued an order permitting the lead plaintiff to file a second amended complaint. That second amended complaint was filed in March 2023. The defendants’ served motions to dismiss the second amended complaint on April 28, 2023. The fully briefed motions to dismiss, including defendants’ opening briefs, lead plaintiff’s opposition and defendants’ replies, were filed with the court on June 30, 2023. No hearing date has yet been set. The Company intends to continue to vigorously defend the case and has not recorded a liability related to this lawsuit because, at this time, the Company is unable to reasonably estimate possible losses or determine whether an unfavorable outcome is either probable or remote. Acuitas Declaratory Judgment Action In March 2022, Acuitas Therapeutics Inc. (“Acuitas”) filed a lawsuit in the U.S. District Court for the Southern District of New York (“SDNY”) against two of the Company’s affiliates, Genevant and Arbutus, seeking a declaratory judgment that certain patents held by Arbutus and licensed by Genevant are not infringed by the manufacture, use, offer for sale, sale or importation into the United States of COMIRNATY, Pfizer’s and BioNTech’s vaccine for COVID-19 and are otherwise invalid. On September 6, 2022, Acuitas filed a First Amended Complaint. In response, on October 4, 2022, Genevant and Arbutus filed a motion to dismiss the first amended complaint for lack of a controversy and supporting brief. Briefing on this motion was completed in mid-November. On August 4, 2023, Acuitas voluntarily dismissed the action in the SDNY and re-filed a complaint in the U.S. District Court for the District of New Jersey. On October 13, 2023, Genevant and Arbutus filed a motion to dismiss the re-filed complaint. No hearing date has been set. Each of Genevant and Arbutus intends to continue to vigorously defend the case. (C) Indemnification Agreements The Company is a party to a number of agreements entered into in the ordinary course of business that contain typical provisions that obligate the Company to indemnify the other parties to such agreements upon the occurrence of certain events. The aggregate maximum potential future liability of the Company under such indemnification provisions is uncertain. The Company also indemnifies each of its directors and officers for certain events or occurrences, subject to certain limits. The maximum amount of potential future indemnification is unlimited; however, the Company currently maintains director and officer liability insurance, which may cover certain liabilities arising from the Company’s obligation to indemnify its directors and officers. To date, the Company has not incurred any material costs related to these indemnification obligations and has not accrued any liabilities related to such obligations in the condensed consolidated financial statements as of December 31, 2023 and March 31, 2023.
