Summary of Significant Accounting Policies (Policies)	12 Months Ended
Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company’s fiscal year ends on March 31, and its first three fiscal quarters end on June 30, September 30 and December 31. The Company manages its operations as a single segment for purposes of assessing performance, making operating decisions, and allocating resources. This one operating and reporting segment primarily focuses on the development and commercialization of innovative medicines in areas of unmet medical need. The accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”). Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative U.S. GAAP included in the Accounting Standards Codification (“ASC”), and Accounting Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Liquidity and Capital Resources	Liquidity and Capital Resources As of March 31, 2022, the Company had approximately $434.2 million in cash, cash equivalents, and marketable securities. The Company believes that its existing cash, cash equivalents, and marketable securities will be sufficient to fund its anticipated operating expenses and capital expenditure requirements for at least the next 12 months from the date of issuance of this Annual Report on Form 10-K (“Annual Report”). In future periods, if the Company’s cash, cash equivalents, marketable securities, and amounts that it expects to generate from product sales and/or third-party collaboration payments are not sufficient to enable the Company to fund its operations, the Company may need to raise additional funds in the form of equity, debt, or from other sources. There can be no assurances that such funding sources will be available at terms acceptable to the Company, or at all. If the Company has insufficient funding to meet its working capital needs, it could be required to delay, limit, reduce, or terminate its drug development programs, commercialization efforts, and/or limit or cease operations.As of March 31, 2022, the Company had approximately $41.3 million of borrowing capacity available to it under the Sumitomo Pharma Loan Agreement (see Note 6(A)). As of March 31, 2022, the Company is also eligible to earn up to $3.6 billion and $122.5 million of additional milestone payments from Pfizer and Richter pursuant to the Pfizer Collaboration and License Agreement (see Note 13(B)) and the Richter Development and Commercialization Agreement (see Note 13(A)), respectively, as well as potential royalty payments on net sales under the Richter Development and Commercialization Agreement.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the accompanying notes, and the reported amounts of revenue and expenses during the reported periods. Actual results could differ materially from those estimates. On an ongoing basis, the Company’s management evaluates its estimates, including those related to valuation of inventories, impairment testing for long-lived-assets, variables used in calculating the fair value of the Company’s equity awards, expected achievement of performance-based vesting criteria for equity awards, variable consideration and other relevant inputs impacting the gross and net revenue recognition, contingent liabilities, recoverability of deferred tax assets, determination of lease term, research and development (“R&D”) expenses and accruals, and effective income tax rates. Management bases estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period, that are not readily apparent from other sources. Estimates and assumptions are periodically reviewed considering changes in circumstances, facts, or experience. Changes in estimates and assumptions are reflected in reported results in the period in which they become known. 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. The Company has assessed the impact that the COVID-19 pandemic and the conflict in Ukraine has had on its operations and financial results as of March 31, 2022, and through May 11, 2022, the issuance date of these consolidated financial statements. The Company’s analysis was informed by the facts and circumstances as they were known to the Company. Through May 11, 2022, the Company’s results of operations and cash flows have not been significantly impacted by the COVID-19 pandemic or the conflict in Ukraine. The Company is not aware of any specific event or circumstance that would require an update to its estimates, judgments, and assumptions or a revision of the carrying value of the Company’s assets or liabilities as of May 11, 2022.
Reclassification	Reclassifications Certain reclassifications have been made to the consolidated statements of cash flows for the years ended March 31, 2021, and 2020 to place them on a comparable basis with the year ended March 31, 2022, regarding the presentation of amortization of operating lease right-of-use assets of $1.5 million and $1.1 million, respectively. The reclassifications had no effect on the previously reported results of operations. The reclassifications had no effect on previously reported cash flows from operating activities in the consolidated statements of cash flows.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk include cash, cash equivalents, and marketable securities. The Company is exposed to credit risk in the event of default by the financial institutions holding its cash and the issuers of its cash equivalents and marketable securities. The Company maintains its cash deposits and cash equivalents in highly-rated, federally-insured financial institutions in excess of federally insured limits. The Company has established guidelines relative to diversification and maturities of investments to maintain safety and liquidity. The Company has not historically experienced any significant credit losses related to these financial instruments and does not believe that it is exposed to any significant credit risk related to these instruments. The Company is also subject to credit risk from accounts receivable from product sales, amount due from its related party, and amounts due from its collaboration and commercialization partners. The Company monitors its exposure and records a reserve against uncollectible amounts as necessary.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents, and Restricted Cash Cash and cash equivalents include cash deposits in banks and all highly liquid investments that are readily convertible to cash (maturity of three months or less at the time of purchase). Interest income consists of interest earned and the accretion of discounts to maturity for cash equivalents and marketable securities. Restricted cash consists of funds held or designated to satisfy the requirements of certain agreements that are restricted in their use. As of March 31, 2022, and 2021, restricted cash includes approximately $7.1 million and $1.0 million, respectively, that is held in an escrow fund for use by Sunovion Pharmaceuticals Inc. (“Sunovion”), a subsidiary of Sumitomo Pharma, to manage payments for rebates, chargebacks, and similar fees pursuant to the Market Access Services Agreement (see Note 6(C)).
Accounts Receivable, Net	Accounts Receivable, Net The Company’s accounts receivable consists of amounts due from customers related to product sales and have standard payment terms. For certain customers, the accounts receivable for the customer is net of prompt payment discounts. The Company monitors the financial performance and creditworthiness of its customers so that it can properly assess and respond to changes in their credit profile. The Company reserves against accounts receivable for estimated losses that may arise from a customer’s inability to pay, and any amounts determined to be uncollectible are written off against the reserve when it is probable that the receivable will not be collected. The Company has historically not experienced significant credit losses and no amounts were reserved for estimated losses as of March 31, 2022, and 2021.
Marketable Debt Securities	Marketable Debt Securities Investments in marketable debt securities are held in custodial accounts at a financial institution and managed by the Company’s investment advisor based on the Company’s investment guidelines. The Company considers all highly liquid investments in securities with a maturity of greater than three months at the time of purchase to be marketable securities. The Company classifies its marketable debt securities as available-for-sale at the time of purchase and reevaluates such designation at each balance sheet date. Unrealized gains and losses on available-for-sale securities are excluded from earnings and are recorded in accumulated other comprehensive (loss) income until realized. Any unrealized losses are evaluated for other-than-temporary impairment at each balance sheet date. Realized gains and losses are determined based on the specific identification method. The Company does not intend to sell its marketable debt securities that are in an unrealized loss position, and it is unlikely that the Company will be required to sell its marketable debt securities before recovery of their amortized cost basis, which may be maturity. Factors considered in determining whether a loss is temporary include the length of time and extent to which the fair value has been less than the amortized cost basis and whether the Company intends to sell the security or whether it is more likely than not that the Company would be required to sell the marketable debt security before recovery of the amortized cost basis. See Note 4 for additional information.
Fair Value Measurements	Fair Value Measurements The Company utilizes fair value measurement guidance prescribed by accounting standards to value its financial instruments. The guidance establishes a fair value hierarchy for financial instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. Fair value is defined as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy contains three levels of inputs that may be used to measure fair value, in accordance with ASC 820, Fair Value Measurement, of which the first two are considered observable and the last is considered unobservable. These levels are as follows: •Level 1—inputs, which include unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access; •Level 2—inputs, which include observable inputs other than Level 1 inputs, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability; and •Level 3—inputs, which include unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the underlying asset or liability. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies, or similar valuation techniques, as well as significant management judgment or estimation. To the extent the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The recorded amounts of certain financial instruments, including cash, cash equivalents, accounts receivable, accounts payable, accrued liabilities, amounts due to Pfizer, and amounts due to and due from related parties, approximate fair value due to their relatively short maturities. Marketable debt securities that are classified as available-for-sale are recorded at estimated fair value and are included in Level 2 of the fair value hierarchy. The fair value of marketable debt securities is based on market prices from a variety of industry standard data providers and generally represents quoted prices for similar assets in active markets or have been derived from observable market data. Cost share advance from Pfizer is recorded at its estimated fair value and is included in Level 2 of the fair value hierarchy. Share-based compensation liabilities related to stock options are remeasured at fair value on a recurring basis using the Black-Scholes option pricing model and are included in Level 2 of the fair value hierarchy. Share-based compensation liabilities related to common shares are remeasured at fair value on a recurring basis and are included in Level 1 of the fair value hierarchy.
Inventories	Inventories The Company values its inventories at the lower-of-cost or net realizable value and determines the cost of inventories using the average-cost method. Net realizable value is the estimated selling prices in the ordinary course of the Company’s business, less reasonably predictable costs of completion, disposal, and transportation. The cost basis of the Company’s inventories is reduced for any products that are considered excessive or obsolete based upon assumptions about future demand and market conditions. Inventories include the cost for raw materials, the cost to manufacture the raw materials into finished goods, and overhead. Due to the nature of the Company’s supply chain process, inventory that is owned by the Company is physically stored at third-party warehouses, logistics providers and contract manufacturing organizations. The Company performs an assessment of the recoverability of inventories during each reporting period and writes down any excess and obsolete inventories to their net realizable value in the period in which the impairment is first identified. If they occur, such impairment charges are recorded as a component of cost of goods sold in the consolidated statements of operations. The Company capitalizes inventory costs associated with products following regulatory approval when based on management’s judgement, future commercialization is considered probable, and the future economic benefit is expected to be realized. As such, the manufacturing costs for product candidates incurred prior to regulatory approval are not capitalized, but rather expensed as R&D expenses when incurred.
Property and Equipment, net	Property and Equipment, net Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, ranging from three to seven years once the asset is installed and placed into service. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful lives of the assets. Maintenance and repairs are charged to expense as incurred. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the consolidated balance sheet and any resulting gain or loss is reflected in operations in the period realized. The Company reviews the recoverability of its long-lived assets, including the related useful lives, whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset might not be recoverable, based on undiscounted cash flows. If such assets are considered to be impaired, an impairment loss is recognized and is measured as the amount by which the carrying amount of the assets exceed their estimated fair value, which is measured based on the projected discounted future net cash flows arising from the assets.
Leases	Leases The Company determines if an arrangement includes a lease at the inception of the agreement. For each of the Company’s lease arrangements, the Company records a right-of-use asset representing the Company’s right to use an underlying asset for the lease term and a lease liability representing the Company’s obligation to make lease payments. Operating lease right-of-use assets and operating lease liabilities are recognized at the lease commencement date based on the net present value of the remaining future minimum lease payments over the lease term. If the interest rate implicit in the Company’s leases is not readily determinable, in determining the weighted-average discount rate used to calculate the net present value of lease payments, the Company utilizes an estimate of its incremental borrowing rate based on market sources including interest rates for companies with similar credit quality for agreements of similar duration, determined by class of underlying asset, to discount the lease payments. Lease expense for the Company’s operating leases is recognized on a straight-line basis over the lease term and variable lease costs are expensed as incurred. The Company elected the practical expedient not to apply the recognition and measurement requirements to short-term leases, which is any lease with a term of one year or less as of the lease commencement date. The lease may require the Company to pay additional amounts for taxes, insurance, maintenance, and other expenses, which are generally referred to as non-lease components. The Company has elected the practical expedient to combine lease and non-lease components. If a lease includes options to extend the lease term, the Company does not assume the option will be exercised in its initial lease term assessment unless there is reasonable certainty that the Company will renew based on an assessment of economic factors present as of the lease commencement date.
Collaborative Arrangements	Collaborative Arrangements The Company may enter into collaboration arrangements with pharmaceutical and biotechnology partners. The Company analyzes its collaboration arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements, to determine whether such arrangements involve joint operating activities performed by the parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. This assessment is performed throughout the life of the arrangement based on changes in responsibilities of all parties in the arrangement. For collaboration arrangements within the scope of ASC 808 that contain multiple units of account, the Company first determines which units of account of the collaboration are deemed to be within the scope of ASC 808 and those that are reflective of a vendor-customer relationship and, therefore, within the scope of ASC 606, Revenue from Contracts with Customers. While ASC 808 defines collaboration arrangements and provides guidance on income statement presentation, classification, and disclosures related to such arrangements, it does not address recognition and measurement matters, such as (1) determining the appropriate unit of account or (2) when the recognition criteria are met. Therefore, the accounting for these arrangements is either based on an analogy to other accounting literature, such as ASC 606, or an accounting policy election by management. For units of account within collaboration arrangements that are accounted for pursuant to ASC 808, an appropriate revenue recognition method is determined and applied consistently. The Company evaluates the presentation of amounts due from its collaborative partners associated with activities in the collaborative arrangements based on the nature of each activity. Amounts received prior to satisfying the revenue recognition criteria are recorded as deferred revenue in the Company’s consolidated balance sheets. If the related efforts underlying the deferred revenue are expected to be satisfied within the next twelve months, the deferred revenue is classified in current liabilities, otherwise it is classified as a non-current liability.
Revenue Recognition	Revenue Recognition For units of account under ASC 606, the Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when or as the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract, determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. License, Milestone and Other Revenue For units of account under ASC 606, the Company applies significant judgment when evaluating whether contractual obligations represent distinct performance obligations, allocating transaction price to performance obligations within a contract, determining when performance obligations have been met, assessing the recognition and future reversal of variable consideration, and determining and applying appropriate methods of measuring progress for performance obligations satisfied over time. These judgments are discussed in more detail below. •Licenses of intellectual property: If the licenses to intellectual property are determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from non-refundable, upfront fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are not distinct from other promises, the Company applies judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, upfront fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the related revenue recognition accordingly. •Milestone payments: At the inception of each arrangement that includes research, development or regulatory milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative standalone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price on a cumulative catch-up basis in earnings in the period of the adjustment. •Royalties and sales-based milestone payments: For arrangements that include sales-based royalties, including sales-based milestone payments based on pre-specified level of sales, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). Product Revenue, net The Company sells its products in the U.S. principally through wholesale and specialty distribution and pharmacy channels (collectively, “customers”). These customers subsequently resell the Company’s products to healthcare providers and patients. In addition to distribution agreements with customers, the Company enters into arrangements with healthcare providers and payors that provide for government-mandated and/or privately-negotiated rebates, chargebacks and discounts with respect to the purchase of the Company’s products. Revenues from product sales are recognized when the customer obtains control of the Company’s products, which occurs at a point in time, typically upon delivery to the customer. Revenues from product sales are recorded at the net sales price, or “transaction price,” which includes estimates of variable consideration for which reserves are established that result from (a) invoice discounts for prompt payment and specialty distributor and specialty pharmacy service fees, (b) government and private payer rebates, chargebacks, discounts and fees, (c) group purchasing organization (“GPO”) discounts, performance rebates and administrative fees, (d) product returns and (e) costs of co-pay assistance programs for patients. These reserves are based on amounts earned or to be claimed on the related sale and are classified as reductions of accounts receivable (if the amount is payable to the customer) or accrued expenses and other current liabilities (if the amount is payable to a party other than a customer). Where appropriate, the Company utilizes the expected value method to determine the appropriate amount for estimates of variable consideration. The estimates of reserves established for variable consideration reflect current contractual and statutory requirements, the Company’s historical experience, specific known market events and trends, industry data and forecasted customer buying and payment patterns. The amount of variable consideration that is included in the transaction price may be constrained and is included in net product revenues only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results vary from the Company’s estimates, the Company adjusts these estimates in the period such change in estimate becomes known, which could affect net product revenue and earnings in the period of the adjustment. More specifically, these adjustments include the following: •Prompt Pay Discounts: The Company generally provides invoice discounts on product sales to its customers for prompt payment. The Company estimates that its customers will earn these discounts and fees, and deducts the full amount of these discounts and fees from its gross product revenues and accounts receivable at the time such revenues are recognized. •Product Returns: Consistent with industry practice, the Company offers its customers limited product return rights for damages, shipment errors, and expiring product; provided that the return is within a specified period around the product expiration date as set forth in the applicable individual distribution agreement. The Company does not allow product returns for product that has been dispensed to a patient. In arriving at its estimate for product returns, the Company considers historical product returns, the underlying product demand, and industry specific data. •Chargebacks: Chargebacks are discounts that occur when contracted customers purchase directly from a specialty distributor. Contracted customers, which currently consist primarily of Public Health Service institutions, Federal government entities purchasing via the Federal Supply Schedule, GPOs, and health maintenance organizations, generally purchase the product at a discounted price. The specialty distributor, in turn, charges back to the Company the difference between the price initially paid by the specialty distributor and the discounted price paid to the specialty distributor by the customer. The allowance for chargebacks is based on actual chargebacks received and an estimate of sales to contracted customers. •Rebates: Allowances for rebates include mandated discounts under the Medicaid Drug Rebate Program and the Medicare Part D prescription drug benefit. Rebates are amounts owed after the final dispensing of the product to a benefit plan participant and are based upon contractual agreements with, or statutory requirements pertaining to, Medicaid and Medicare benefit providers. The allowance for rebates is based on statutory discount rates, estimated payor mix, and expected utilization. The Company’s estimates for expected utilization of rebates are based on historical data received from specialty pharmacies and specialty distributors since launch, as well as analog data from similar products. The Company monitors sales trends and adjusts the allowance on a regular basis to reflect the most recent rebate experience. The Company’s liability for these rebates consists of invoices received, estimates of claims for the current quarter, and estimated future claims that will be made for product that has been recognized as revenue, but remains in the distribution channel inventories at the end of each reporting period. •Co-payment Assistance: The Company offers co-payment assistance to commercially insured patients meeting certain eligibility requirements. Co-payment assistance is accrued based on actual program participation and estimates of program redemption using data provided by third-party administrators. •Customer Fees: The Company pays fees to its customers for account management, data management, and other administrative services. To the extent the services received are distinct from sales of products to the customer, the Company records these payments in Selling General and Administrative (“SG&A”) expenses.
Cost of Product Revenue	Cost of Product Revenue Cost of product revenue is composed of the cost of goods sold and royalty expense payable to Takeda. Cost of goods sold consists of the cost of raw materials, third-party manufacturing costs to manufacture the raw materials into finished product, freight, and indirect overhead costs associated with sales of ORGOVYX and MYFEMBREE in the U.S. and sales of product supply to Richter. The cost of inventories written down as a result of excess, obsolescence, or other reasons is also charged to cost of goods sold. Royalty expense consists of royalties on net sales of relugolix payable to Takeda pursuant to the terms of the Takeda License Agreement (see Note 14(D)). As a result of the FDA approvals of ORGOVYX and MYFEMBREE, the Company subsequently began capitalizing inventories manufactured or purchased for each product after its respective approval date. As a result, certain manufacturing costs of ORGOVYX and MYFEMBREE were expensed as R&D expenses prior to FDA approval and, therefore, these costs are not included in cost of goods sold. Collaboration Expense to Pfizer Collaboration expense to Pfizer consists of Pfizer’s 50% share of net profits from sales of ORGOVYX and MYFEMBREE in the U.S. (see Note 13(B)).
Research and Development Expenses	Research and Development Expenses R&D expenses consist primarily of employee-related expenses, such as salaries, share-based compensation, benefits and travel expenses for employees engaged in R&D activities, expenses from third parties who conduct R&D activities on behalf of the Company, investigator grants, sponsored research, and fees incurred for regulatory submissions. R&D costs are expensed as incurred. Clinical study costs are accrued over the service periods specified in the contracts and adjusted as necessary based on an ongoing review of the level of effort and costs actually incurred. The Company expenses in-process R&D projects acquired as asset acquisitions which have not reached technological feasibility, and which have no alternative future use. The Company considers regulatory approval of product candidates to be uncertain and products manufactured prior to regulatory approval may not be sold unless regulatory approval is obtained. As such, the manufacturing costs for product candidates incurred prior to regulatory approval are not capitalized as inventory, but rather expensed as R&D expenses when incurred.
Promotional and Advertising Expense	Promotional and Advertising ExpensePromotional and advertising costs are expensed as incurred, and are included in SG&A expenses in the consolidated statements of operations. Promotional and advertising costs consist primarily of the costs of designing, producing, and distributing materials promoting the Company’s products. Certain promotional and advertising costs are shared with Pfizer pursuant to the Pfizer Collaboration and License Agreement (see Note 13(B)).
Share-Based Compensation	Share-Based Compensation The Company accounts for share-based compensation plans using the fair value recognition and measurement provisions under U.S. GAAP. The Company’s share-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense on a straight-line basis over the requisite service period, which is generally the vesting period of the respective award. The Company recognizes forfeitures in the period in which such forfeiture occurs and records share-based compensation as though all awards are expected to vest. The Company estimates the grant date fair value of stock options, and the resulting share-based compensation, using the Black-Scholes option-pricing model, which requires the use of subjective assumptions. These assumptions include: •Expected Term. The expected term represents the period that the Company’s share-based awards are expected to be outstanding and is determined using the simplified method in accordance with the Securities and Exchange Commission (“SEC”), Staff Accounting Bulletin (“SAB”) No. 107 and No. 110 (based on the mid-point between the vesting date and the end of the contractual term). •Expected Volatility. The expected volatility considers the Company’s historical volatility and weighted average measures of volatility of a peer group of companies for a period equal to the expected term of the stock options. The Company’s peer group of publicly traded biopharmaceutical companies was chosen based on their similar size, stage in the life cycle or area of specialty. •Risk-Free Interest Rate. The risk-free interest rate is based on the U.S. treasury yield curve in effect at the time of grant for the expected term of the stock option. •Expected Dividend. The Company has never paid, and does not anticipate paying, cash dividends on its common shares. Therefore, the expected dividend yield was assumed to be zero. The fair value of stock options on the grant date is estimated using the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including the option’s expected term and the price volatility of the underlying stock, to determine the fair value of the award. The Company recognizes the expense associated with options using a single award approach over the requisite service period. Share-based compensation associated with restricted stock units (“RSU”) and performance share units (“PSU”) is based on the fair value of the Company’s common shares on the grant date, which equals the closing market price of the Company’s common shares on the grant date. The Company recognizes the share-based compensation related to RSUs on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. The Company recognizes the share-based compensation related to PSUs if the performance criteria are deemed probable of being met. Share-based compensation liabilities (a current liability) are remeasured at fair value each reporting period until the common share awards are settled or become mature, with the change in fair value recorded as share-based compensation. No tax benefits for share-based compensation have been recognized in the consolidated statements of shareholders’ deficit or consolidated statements of cash flows. The Company has not recognized, and does not expect to recognize in the near future, any tax benefits related to share-based compensation as a result of its full valuation allowance on net deferred tax assets and net operating loss carryforwards.
Income Taxes	Income Taxes The Company is subject to income taxes in the United States and other foreign jurisdictions. Judgment is required in determining the Company’s expense (benefit) for income taxes and income tax assets and liabilities, including evaluating uncertainties in the application of accounting principles and complex tax laws. The Company records an expense (benefit) for income taxes for the anticipated tax consequences of the reported results of operations using the asset and liability method. Under this method, the Company recognizes deferred income tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as for loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. The Company recognizes the deferred income tax effects of a change in tax rates in the period of enactment. The Company records a valuation allowance to reduce the Company’s deferred tax assets to the net amount that the Company believes is more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and results of operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. The Company recognizes tax benefits from uncertain tax positions if the Company believes that it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position as well as consideration of the available facts and circumstances. Interest and/or penalties related to income tax matters are recognized as a component of income tax expense as incurred.
Net Loss Per Common Share	Net Loss per Common Share Basic net loss per common share is computed by dividing net loss available to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per common share is computed by dividing net loss by the weighted-average number of common shares and potentially dilutive shares of common stock outstanding during the period. Potential dilutive securities outstanding include stock options, restricted stock units, performance stock units, and warrants. During all periods presented, the Company incurred net losses. Accordingly, the effect of any common share equivalents would have been anti-dilutive during those periods and are not included in the calculation of diluted weighted-average number of common shares outstanding.
Change in Functional Currency	Change in Functional Currency Prior to December 1, 2020, the functional currency of the Company’s wholly-owned subsidiary in Switzerland, Myovant Sciences GmbH (“MSG”), was the local currency where the subsidiary is located, the Swiss franc. Transactions in foreign currencies were translated to the functional currency at the rate of exchange at the date of the transaction. Transaction gains and losses were recognized in foreign exchange (gain) loss in the consolidated statements of operations. The results of operations of MSG were translated to the U.S. dollar, the Company’s reporting currency, at the average rates of exchange during the period. The cumulative effect of these exchange rate adjustments was included in a separate component of other comprehensive income (loss) on the consolidated balance sheets. Effective December 1, 2020, as a result of significant changes in economic facts and circumstances in the operations of MSG, the functional currency of MSG was changed from the Swiss franc to the U.S. dollar. The change in the functional currency was accounted for prospectively from December 1, 2020. Therefore, any gains or losses that were previously recorded in accumulated other comprehensive income (loss) remain unchanged.
Pushdown Accounting	Pushdown AccountingIn November 2014, the FASB issued ASU 2014-17, Business Combinations (Topic 805): Pushdown Accounting. The ASU provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change in control event occurs. If pushdown accounting is applied to an individual change in control event, that election is irrevocable. The Company elected not to apply pushdown accounting in its consolidated financial statements upon the change in control of the Company on December 27, 2019.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Standards In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”), that eliminates certain exceptions to the general principles in ASC 740 related to intra-period tax allocation, deferred tax liability and general methodology for calculating income taxes. ASU 2019-12 also simplifies U.S. GAAP by making other changes for matters such as, franchise taxes that are partially based on income, transactions with a government that result in a step up in the tax basis of goodwill, separate financial statements of legal entities that are not subject to tax, and enacted changes in tax laws in interim periods. The Company adopted ASU 2019-12 on April 1, 2021, which did not have a material impact on the Company’s consolidated financial statements and related disclosures. Recently Issued Accounting Standards Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. These amendments apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The amendments are effective prospectively for all entities as of March 12, 2020 through December 31, 2022. The Company’s outstanding debt with Sumitomo Pharma bears a variable interest rate that is indexed off of 3-month LIBOR, for which publication is expected to be discontinued on June 30, 2023. In the event that 3-month LIBOR becomes unavailable, the Company and Sumitomo Pharma will negotiate in good faith to select an alternative interest rate in accordance with the Sumitomo Pharma Loan Agreement. The Company has not yet adopted this guidance and is currently evaluating the potential impact the adoption of this standard will have on its consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model that requires the use of forward-looking information to calculate credit loss estimates. It also eliminates the concept of other-than-temporary impairment and requires credit losses on available-for-sale debt securities to be recorded through an allowance for credit losses instead of as a reduction in the amortized cost basis of the securities. ASU 2016-13 was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2019. Early adoption was permitted, including adoption in any interim period. In February 2020, the FASB issued ASU 2020-02, Financial Instruments-Credit Losses (Topic 326) and Leases (Topic 842) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842), which amended the effective date of the original pronouncement for smaller reporting companies. ASC 2016-13 and its amendments will be effective for annual and interim periods beginning after December 15, 2022 for smaller reporting companies. The Company is currently assessing the impact the adoption of this new standard will have on its consolidated financial statements and related disclosures. The Company adopted ASU 2016-2, Leases, (Topic 842) as of April 1, 2019 on a modified retrospective basis and did not restate comparative periods as permitted under the transition guidance. The Company elected the practical expedient not to apply the recognition and measurement guidance of Topic 842 to short-term leases.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Mar. 31, 2022

The Company’s fiscal year ends on March 31, and its first three fiscal quarters end on June 30, September 30 and December 31. The Company manages its operations as a single segment for purposes of assessing performance, making operating decisions, and allocating resources. This one operating and reporting segment primarily focuses on the development and commercialization of innovative medicines in areas of unmet medical need.

The accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”). Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative U.S. GAAP included in the Accounting Standards Codification (“ASC”), and Accounting Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Liquidity and Capital Resources

As of March 31, 2022, the Company had approximately $434.2 million in cash, cash equivalents, and marketable securities. The Company believes that its existing cash, cash equivalents, and marketable securities will be sufficient to fund its anticipated operating expenses and capital expenditure requirements for at least the next 12 months from the date of issuance of this Annual Report on Form 10-K (“Annual Report”).

In future periods, if the Company’s cash, cash equivalents, marketable securities, and amounts that it expects to generate from product sales and/or third-party collaboration payments are not sufficient to enable the Company to fund its operations, the

Company may need to raise additional funds in the form of equity, debt, or from other sources. There can be no assurances that such funding sources will be available at terms acceptable to the Company, or at all. If the Company has insufficient funding to meet its working capital needs, it could be required to delay, limit, reduce, or terminate its drug development programs, commercialization efforts, and/or limit or cease operations.As of March 31, 2022, the Company had approximately $41.3 million of borrowing capacity available to it under the Sumitomo Pharma Loan Agreement (see Note 6(A)). As of March 31, 2022, the Company is also eligible to earn up to $3.6 billion and $122.5 million of additional milestone payments from Pfizer and Richter pursuant to the Pfizer Collaboration and License Agreement (see Note 13(B)) and the Richter Development and Commercialization Agreement (see Note 13(A)), respectively, as well as potential royalty payments on net sales under the Richter Development and Commercialization Agreement.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the accompanying notes, and the reported amounts of revenue and expenses during the reported periods. Actual results could differ materially from those estimates.

On an ongoing basis, the Company’s management evaluates its estimates, including those related to valuation of inventories, impairment testing for long-lived-assets, variables used in calculating the fair value of the Company’s equity awards, expected achievement of performance-based vesting criteria for equity awards, variable consideration and other relevant inputs impacting the gross and net revenue recognition, contingent liabilities, recoverability of deferred tax assets, determination of lease term, research and development (“R&D”) expenses and accruals, and effective income tax rates. Management bases estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period, that are not readily apparent from other sources. Estimates and assumptions are periodically reviewed considering changes in circumstances, facts, or experience. Changes in estimates and assumptions are reflected in reported results in the period in which they become known. 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.

The Company has assessed the impact that the COVID-19 pandemic and the conflict in Ukraine has had on its operations and financial results as of March 31, 2022, and through May 11, 2022, the issuance date of these consolidated financial statements. The Company’s analysis was informed by the facts and circumstances as they were known to the Company. Through May 11, 2022, the Company’s results of operations and cash flows have not been significantly impacted by the COVID-19 pandemic or the conflict in Ukraine. The Company is not aware of any specific event or circumstance that would require an update to its estimates, judgments, and assumptions or a revision of the carrying value of the Company’s assets or liabilities as of May 11, 2022.

Reclassification

Reclassifications

Certain reclassifications have been made to the consolidated statements of cash flows for the years ended March 31, 2021, and 2020 to place them on a comparable basis with the year ended March 31, 2022, regarding the presentation of amortization of operating lease right-of-use assets of $1.5 million and $1.1 million, respectively. The reclassifications had no effect on the previously reported results of operations. The reclassifications had no effect on previously reported cash flows from operating activities in the consolidated statements of cash flows.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk include cash, cash equivalents, and marketable securities. The Company is exposed to credit risk in the event of default by the financial institutions holding its cash and the issuers of its cash equivalents and marketable securities. The Company maintains its cash deposits and cash equivalents in highly-rated, federally-insured financial institutions in excess of federally insured limits. The Company has established guidelines relative to diversification and maturities of investments to maintain safety and liquidity. The Company has not historically experienced any significant credit losses related to these financial instruments and does not believe that it is exposed to any significant credit risk related to these instruments.

The Company is also subject to credit risk from accounts receivable from product sales, amount due from its related party, and amounts due from its collaboration and commercialization partners. The Company monitors its exposure and records a reserve against uncollectible amounts as necessary.

Cash, Cash Equivalents and Restricted Cash

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents include cash deposits in banks and all highly liquid investments that are readily convertible to cash (maturity of three months or less at the time of purchase). Interest income consists of interest earned and the accretion of discounts to maturity for cash equivalents and marketable securities.

Restricted cash consists of funds held or designated to satisfy the requirements of certain agreements that are restricted in their use. As of March 31, 2022, and 2021, restricted cash includes approximately $7.1 million and $1.0 million, respectively, that is held in an escrow fund for use by Sunovion Pharmaceuticals Inc. (“Sunovion”), a subsidiary of Sumitomo Pharma, to manage payments for rebates, chargebacks, and similar fees pursuant to the Market Access Services Agreement (see Note 6(C)).

Accounts Receivable, Net

The Company’s accounts receivable consists of amounts due from customers related to product sales and have standard payment terms. For certain customers, the accounts receivable for the customer is net of prompt payment discounts. The Company monitors the financial performance and creditworthiness of its customers so that it can properly assess and respond to changes in their credit profile. The Company reserves against accounts receivable for estimated losses that may arise from a customer’s inability to pay, and any amounts determined to be uncollectible are written off against the reserve when it is probable that the receivable will not be collected. The Company has historically not experienced significant credit losses and no amounts were reserved for estimated losses as of March 31, 2022, and 2021.

Marketable Debt Securities

Investments in marketable debt securities are held in custodial accounts at a financial institution and managed by the Company’s investment advisor based on the Company’s investment guidelines. The Company considers all highly liquid investments in securities with a maturity of greater than three months at the time of purchase to be marketable securities.

The Company classifies its marketable debt securities as available-for-sale at the time of purchase and reevaluates such designation at each balance sheet date. Unrealized gains and losses on available-for-sale securities are excluded from earnings and are recorded in accumulated other comprehensive (loss) income until realized. Any unrealized losses are evaluated for

other-than-temporary impairment at each balance sheet date. Realized gains and losses are determined based on the specific identification method.

The Company does not intend to sell its marketable debt securities that are in an unrealized loss position, and it is unlikely that the Company will be required to sell its marketable debt securities before recovery of their amortized cost basis, which may be maturity. Factors considered in determining whether a loss is temporary include the length of time and extent to which the fair value has been less than the amortized cost basis and whether the Company intends to sell the security or whether it is more likely than not that the Company would be required to sell the marketable debt security before recovery of the amortized cost basis. See Note 4 for additional information.

Fair Value Measurements

The Company utilizes fair value measurement guidance prescribed by accounting standards to value its financial instruments. The guidance establishes a fair value hierarchy for financial instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances.

Fair value is defined as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy contains three levels of inputs that may be used to measure fair value, in accordance with ASC 820, Fair Value Measurement, of which the first two are considered observable and the last is considered unobservable. These levels are as follows:

•Level 1—inputs, which include unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access;

•Level 2—inputs, which include observable inputs other than Level 1 inputs, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability; and

•Level 3—inputs, which include unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the underlying asset or liability. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies, or similar valuation techniques, as well as significant management judgment or estimation.

To the extent the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The recorded amounts of certain financial instruments, including cash, cash equivalents, accounts receivable, accounts payable, accrued liabilities, amounts due to Pfizer, and amounts due to and due from related parties, approximate fair value due to their relatively short maturities. Marketable debt securities that are classified as available-for-sale are recorded at estimated fair value and are included in Level 2 of the fair value hierarchy. The fair value of marketable debt securities is based on market prices from a variety of industry standard data providers and generally represents quoted prices for similar assets in active markets or have been derived from observable market data. Cost share advance from Pfizer is recorded at its estimated fair value and is included in Level 2 of the fair value hierarchy. Share-based compensation liabilities related to stock options are remeasured at fair value on a recurring basis using the Black-Scholes option pricing model and are included in Level 2 of the fair value hierarchy. Share-based compensation liabilities related to common shares are remeasured at fair value on a recurring basis and are included in Level 1 of the fair value hierarchy.

Inventories

The Company values its inventories at the lower-of-cost or net realizable value and determines the cost of inventories using the average-cost method. Net realizable value is the estimated selling prices in the ordinary course of the Company’s business, less reasonably predictable costs of completion, disposal, and transportation. The cost basis of the Company’s inventories is reduced for any products that are considered excessive or obsolete based upon assumptions about future demand and market conditions.

Inventories include the cost for raw materials, the cost to manufacture the raw materials into finished goods, and overhead. Due to the nature of the Company’s supply chain process, inventory that is owned by the Company is physically stored at third-party warehouses, logistics providers and contract manufacturing organizations.

The Company performs an assessment of the recoverability of inventories during each reporting period and writes down any excess and obsolete inventories to their net realizable value in the period in which the impairment is first identified. If they occur, such impairment charges are recorded as a component of cost of goods sold in the consolidated statements of operations.

The Company capitalizes inventory costs associated with products following regulatory approval when based on management’s judgement, future commercialization is considered probable, and the future economic benefit is expected to be realized. As such, the manufacturing costs for product candidates incurred prior to regulatory approval are not capitalized, but rather expensed as R&D expenses when incurred.

Property and Equipment, net

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, ranging from three to seven years once the asset is installed and placed into service. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful lives of the assets. Maintenance and repairs are charged to expense as incurred. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the consolidated balance sheet and any resulting gain or loss is reflected in operations in the period realized.

The Company reviews the recoverability of its long-lived assets, including the related useful lives, whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset might not be recoverable, based on undiscounted cash flows. If such assets are considered to be impaired, an impairment loss is recognized and is measured as the amount by which the carrying amount of the assets exceed their estimated fair value, which is measured based on the projected discounted future net cash flows arising from the assets.

Leases

The Company determines if an arrangement includes a lease at the inception of the agreement. For each of the Company’s lease arrangements, the Company records a right-of-use asset representing the Company’s right to use an underlying asset for the lease term and a lease liability representing the Company’s obligation to make lease payments. Operating lease right-of-use assets and operating lease liabilities are recognized at the lease commencement date based on the net present value of the remaining future minimum lease payments over the lease term. If the interest rate implicit in the Company’s leases is not readily determinable, in determining the weighted-average discount rate used to calculate the net present value of lease payments, the Company utilizes an estimate of its incremental borrowing rate based on market sources including interest rates for companies with similar credit quality for agreements of similar duration, determined by class of underlying asset, to discount the lease payments. Lease expense for the Company’s operating leases is recognized on a straight-line basis over the lease term and variable lease costs are expensed as incurred.

The Company elected the practical expedient not to apply the recognition and measurement requirements to short-term leases, which is any lease with a term of one year or less as of the lease commencement date. The lease may require the Company to pay additional amounts for taxes, insurance, maintenance, and other expenses, which are generally referred to as non-lease components. The Company has elected the practical expedient to combine lease and non-lease components. If a lease includes options to extend the lease term, the Company does not assume the option will be exercised in its initial lease term assessment unless there is reasonable certainty that the Company will renew based on an assessment of economic factors present as of the lease commencement date.

Collaborative Arrangements

The Company may enter into collaboration arrangements with pharmaceutical and biotechnology partners. The Company analyzes its collaboration arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements, to determine whether such arrangements involve joint operating activities performed by the parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. This assessment is performed throughout the life of the arrangement based on changes in responsibilities of all parties in the arrangement. For collaboration arrangements within the scope of ASC 808 that contain multiple units of account, the Company first determines which units of account of the collaboration are deemed to be within the scope of ASC 808 and those that are reflective of a vendor-customer relationship and, therefore, within the scope of ASC 606, Revenue from Contracts with Customers.

While ASC 808 defines collaboration arrangements and provides guidance on income statement presentation, classification, and disclosures related to such arrangements, it does not address recognition and measurement matters, such as (1) determining the appropriate unit of account or (2) when the recognition criteria are met. Therefore, the accounting for these arrangements is either based on an analogy to other accounting literature, such as ASC 606, or an accounting policy election by management. For units of account within collaboration arrangements that are accounted for pursuant to ASC 808, an appropriate revenue recognition method is determined and applied consistently.

The Company evaluates the presentation of amounts due from its collaborative partners associated with activities in the collaborative arrangements based on the nature of each activity. Amounts received prior to satisfying the revenue recognition criteria are recorded as deferred revenue in the Company’s consolidated balance sheets. If the related efforts underlying the deferred revenue are expected to be satisfied within the next twelve months, the deferred revenue is classified in current liabilities, otherwise it is classified as a non-current liability.

Revenue Recognition

For units of account under ASC 606, the Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when or as the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract, determines those that are performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

License, Milestone and Other Revenue

For units of account under ASC 606, the Company applies significant judgment when evaluating whether contractual obligations represent distinct performance obligations, allocating transaction price to performance obligations within a contract, determining when performance obligations have been met, assessing the recognition and future reversal of variable consideration, and determining and applying appropriate methods of measuring progress for performance obligations satisfied over time. These judgments are discussed in more detail below.

•Licenses of intellectual property: If the licenses to intellectual property are determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from non-refundable, upfront fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are not distinct from other promises, the Company applies judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, upfront fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the related revenue recognition accordingly.

•Milestone payments: At the inception of each arrangement that includes research, development or regulatory milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative standalone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price on a cumulative catch-up basis in earnings in the period of the adjustment.

•Royalties and sales-based milestone payments: For arrangements that include sales-based royalties, including sales-based milestone payments based on pre-specified level of sales, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Product Revenue, net

The Company sells its products in the U.S. principally through wholesale and specialty distribution and pharmacy channels (collectively, “customers”). These customers subsequently resell the Company’s products to healthcare providers and patients. In addition to distribution agreements with customers, the Company enters into arrangements with healthcare providers and payors that provide for government-mandated and/or privately-negotiated rebates, chargebacks and discounts with respect to the purchase of the Company’s products. Revenues from product sales are recognized when the customer obtains control of the Company’s products, which occurs at a point in time, typically upon delivery to the customer.

Revenues from product sales are recorded at the net sales price, or “transaction price,” which includes estimates of variable consideration for which reserves are established that result from (a) invoice discounts for prompt payment and specialty distributor and specialty pharmacy service fees, (b) government and private payer rebates, chargebacks, discounts and fees, (c) group purchasing organization (“GPO”) discounts, performance rebates and administrative fees, (d) product returns and (e) costs of co-pay assistance programs for patients. These reserves are based on amounts earned or to be claimed on the related sale and are classified as reductions of accounts receivable (if the amount is payable to the customer) or accrued expenses and other current liabilities (if the amount is payable to a party other than a customer). Where appropriate, the Company utilizes the expected value method to determine the appropriate amount for estimates of variable consideration. The estimates of reserves established for variable consideration reflect current contractual and statutory requirements, the Company’s historical experience, specific known market events and trends, industry data and forecasted customer buying and payment patterns. The amount of variable consideration that is included in the transaction price may be constrained and is included in net product revenues only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results vary from the Company’s estimates, the Company adjusts these estimates in the period such change in estimate becomes known, which could affect net product revenue and earnings in the period of the adjustment.

More specifically, these adjustments include the following:

•Prompt Pay Discounts: The Company generally provides invoice discounts on product sales to its customers for prompt payment. The Company estimates that its customers will earn these discounts and fees, and deducts the full amount of these discounts and fees from its gross product revenues and accounts receivable at the time such revenues are recognized.

•Product Returns: Consistent with industry practice, the Company offers its customers limited product return rights for damages, shipment errors, and expiring product; provided that the return is within a specified period around the product expiration date as set forth in the applicable individual distribution agreement. The Company does not allow product returns for product that has been dispensed to a patient. In arriving at its estimate for product returns, the Company considers historical product returns, the underlying product demand, and industry specific data.

•Chargebacks: Chargebacks are discounts that occur when contracted customers purchase directly from a specialty distributor. Contracted customers, which currently consist primarily of Public Health Service institutions, Federal government entities purchasing via the Federal Supply Schedule, GPOs, and health maintenance organizations, generally purchase the product at a discounted price. The specialty distributor, in turn, charges back to the Company the difference between the price initially paid by the specialty distributor and the discounted price paid to the specialty distributor by the customer. The allowance for chargebacks is based on actual chargebacks received and an estimate of sales to contracted customers.

•Rebates: Allowances for rebates include mandated discounts under the Medicaid Drug Rebate Program and the Medicare Part D prescription drug benefit. Rebates are amounts owed after the final dispensing of the product to a benefit plan participant and are based upon contractual agreements with, or statutory requirements pertaining to, Medicaid and Medicare benefit providers. The allowance for rebates is based on statutory discount rates, estimated payor mix, and expected utilization. The Company’s estimates for expected utilization of rebates are based on historical data received from specialty pharmacies and specialty distributors since launch, as well as analog data from similar products. The Company monitors sales trends and adjusts the allowance on a regular basis to reflect the most recent rebate experience. The Company’s liability for these rebates consists of invoices received, estimates of claims for the current quarter, and estimated future claims that will be made for product that has been recognized as revenue, but remains in the distribution channel inventories at the end of each reporting period.

•Co-payment Assistance: The Company offers co-payment assistance to commercially insured patients meeting certain eligibility requirements. Co-payment assistance is accrued based on actual program participation and estimates of program redemption using data provided by third-party administrators.

•Customer Fees: The Company pays fees to its customers for account management, data management, and other administrative services. To the extent the services received are distinct from sales of products to the customer, the Company records these payments in Selling General and Administrative (“SG&A”) expenses.

Cost of Product Revenue

Cost of product revenue is composed of the cost of goods sold and royalty expense payable to Takeda. Cost of goods sold consists of the cost of raw materials, third-party manufacturing costs to manufacture the raw materials into finished product, freight, and indirect overhead costs associated with sales of ORGOVYX and MYFEMBREE in the U.S. and sales of product supply to Richter. The cost of inventories written down as a result of excess, obsolescence, or other reasons is also charged to cost of goods sold. Royalty expense consists of royalties on net sales of relugolix payable to Takeda pursuant to the terms of the Takeda License Agreement (see Note 14(D)).

As a result of the FDA approvals of ORGOVYX and MYFEMBREE, the Company subsequently began capitalizing inventories manufactured or purchased for each product after its respective approval date. As a result, certain manufacturing costs of ORGOVYX and MYFEMBREE were expensed as R&D expenses prior to FDA approval and, therefore, these costs are not included in cost of goods sold.

Collaboration Expense to Pfizer

Collaboration expense to Pfizer consists of Pfizer’s 50% share of net profits from sales of ORGOVYX and MYFEMBREE in the U.S. (see Note 13(B)).

Research and Development Expenses

R&D expenses consist primarily of employee-related expenses, such as salaries, share-based compensation, benefits and travel expenses for employees engaged in R&D activities, expenses from third parties who conduct R&D activities on behalf of the Company, investigator grants, sponsored research, and fees incurred for regulatory submissions.

R&D costs are expensed as incurred. Clinical study costs are accrued over the service periods specified in the contracts and adjusted as necessary based on an ongoing review of the level of effort and costs actually incurred. The Company expenses in-process R&D projects acquired as asset acquisitions which have not reached technological feasibility, and which have no alternative future use.

The Company considers regulatory approval of product candidates to be uncertain and products manufactured prior to regulatory approval may not be sold unless regulatory approval is obtained. As such, the manufacturing costs for product candidates incurred prior to regulatory approval are not capitalized as inventory, but rather expensed as R&D expenses when incurred.

Promotional and Advertising Expense

Promotional and Advertising ExpensePromotional and advertising costs are expensed as incurred, and are included in SG&A expenses in the consolidated statements of operations. Promotional and advertising costs consist primarily of the costs of designing, producing, and distributing materials promoting the Company’s products. Certain promotional and advertising costs are shared with Pfizer pursuant to the Pfizer Collaboration and License Agreement (see Note 13(B)).

Share-Based Compensation

The Company accounts for share-based compensation plans using the fair value recognition and measurement provisions under U.S. GAAP. The Company’s share-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense on a straight-line basis over the requisite service period, which is generally the vesting period of the respective award. The Company recognizes forfeitures in the period in which such forfeiture occurs and records share-based compensation as though all awards are expected to vest.

The Company estimates the grant date fair value of stock options, and the resulting share-based compensation, using the Black-Scholes option-pricing model, which requires the use of subjective assumptions. These assumptions include:

•Expected Term. The expected term represents the period that the Company’s share-based awards are expected to be outstanding and is determined using the simplified method in accordance with the Securities and Exchange Commission (“SEC”), Staff Accounting Bulletin (“SAB”) No. 107 and No. 110 (based on the mid-point between the vesting date and the end of the contractual term).

•Expected Volatility. The expected volatility considers the Company’s historical volatility and weighted average measures of volatility of a peer group of companies for a period equal to the expected term of the stock options. The Company’s peer group of publicly traded biopharmaceutical companies was chosen based on their similar size, stage in the life cycle or area of specialty.

•Risk-Free Interest Rate. The risk-free interest rate is based on the U.S. treasury yield curve in effect at the time of grant for the expected term of the stock option.

•Expected Dividend. The Company has never paid, and does not anticipate paying, cash dividends on its common shares. Therefore, the expected dividend yield was assumed to be zero.

The fair value of stock options on the grant date is estimated using the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including the option’s expected term and the price volatility of the underlying stock, to determine the fair value of the award. The Company recognizes the expense associated with options using a single award approach over the requisite service period.

Share-based compensation associated with restricted stock units (“RSU”) and performance share units (“PSU”) is based on the fair value of the Company’s common shares on the grant date, which equals the closing market price of the Company’s common shares on the grant date. The Company recognizes the share-based compensation related to RSUs on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. The Company recognizes the share-based compensation related to PSUs if the performance criteria are deemed probable of being met. Share-based compensation liabilities (a current liability) are remeasured at fair value each reporting period until the common share awards are settled or become mature, with the change in fair value recorded as share-based compensation.

No tax benefits for share-based compensation have been recognized in the consolidated statements of shareholders’ deficit or consolidated statements of cash flows. The Company has not recognized, and does not expect to recognize in the near future, any tax benefits related to share-based compensation as a result of its full valuation allowance on net deferred tax assets and net operating loss carryforwards.

Income Taxes

The Company is subject to income taxes in the United States and other foreign jurisdictions. Judgment is required in determining the Company’s expense (benefit) for income taxes and income tax assets and liabilities, including evaluating uncertainties in the application of accounting principles and complex tax laws.

The Company records an expense (benefit) for income taxes for the anticipated tax consequences of the reported results of operations using the asset and liability method. Under this method, the Company recognizes deferred income tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as for loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. The Company recognizes the deferred income tax effects of a change in tax rates in the period of enactment.

The Company records a valuation allowance to reduce the Company’s deferred tax assets to the net amount that the Company believes is more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and results of operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company recognizes tax benefits from uncertain tax positions if the Company believes that it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position as well as consideration of the available facts and circumstances. Interest and/or penalties related to income tax matters are recognized as a component of income tax expense as incurred.

Net Loss Per Common Share

Net Loss per Common Share

Basic net loss per common share is computed by dividing net loss available to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per common share is computed by dividing net loss by the weighted-average number of common shares and potentially dilutive shares of common stock outstanding during the period. Potential dilutive securities outstanding include stock options, restricted stock units, performance stock units, and warrants. During all periods presented, the Company incurred net losses. Accordingly, the effect of any common share

equivalents would have been anti-dilutive during those periods and are not included in the calculation of diluted weighted-average number of common shares outstanding.

Change in Functional Currency

Prior to December 1, 2020, the functional currency of the Company’s wholly-owned subsidiary in Switzerland, Myovant Sciences GmbH (“MSG”), was the local currency where the subsidiary is located, the Swiss franc. Transactions in foreign currencies were translated to the functional currency at the rate of exchange at the date of the transaction. Transaction gains and losses were recognized in foreign exchange (gain) loss in the consolidated statements of operations. The results of operations of MSG were translated to the U.S. dollar, the Company’s reporting currency, at the average rates of exchange during the period. The cumulative effect of these exchange rate adjustments was included in a separate component of other comprehensive income (loss) on the consolidated balance sheets.

Effective December 1, 2020, as a result of significant changes in economic facts and circumstances in the operations of MSG, the functional currency of MSG was changed from the Swiss franc to the U.S. dollar. The change in the functional currency was accounted for prospectively from December 1, 2020. Therefore, any gains or losses that were previously recorded in accumulated other comprehensive income (loss) remain unchanged.

Pushdown Accounting

Pushdown AccountingIn November 2014, the FASB issued ASU 2014-17, Business Combinations (Topic 805): Pushdown Accounting. The ASU provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change in control event occurs. If pushdown accounting is applied to an individual change in control event, that election is irrevocable. The Company elected not to apply pushdown accounting in its consolidated financial statements upon the change in control of the Company on December 27, 2019.

Recently Adopted and Issued Accounting Pronouncements

Recently Adopted Accounting Standards

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”), that eliminates certain exceptions to the general principles in ASC 740 related to intra-period tax allocation, deferred tax liability and general methodology for calculating income taxes. ASU 2019-12 also simplifies U.S. GAAP by making other changes for matters such as, franchise taxes that are partially based on income, transactions with a government that result in a step up in the tax basis of goodwill, separate financial statements of legal entities that are not subject to tax, and enacted changes in tax laws in interim periods. The Company adopted ASU 2019-12 on April 1, 2021, which did not have a material impact on the Company’s consolidated financial statements and related disclosures.

Recently Issued Accounting Standards Not Yet Adopted

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. These amendments apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The amendments are effective prospectively for all entities as of March 12, 2020 through December 31, 2022. The Company’s outstanding debt with Sumitomo Pharma bears a variable interest rate that is indexed off of 3-month LIBOR, for which publication is expected to be discontinued on June 30, 2023. In the event that 3-month LIBOR becomes unavailable, the Company and Sumitomo Pharma will negotiate in good faith to select an alternative interest rate in accordance with the

Sumitomo Pharma Loan Agreement. The Company has not yet adopted this guidance and is currently evaluating the potential impact the adoption of this standard will have on its consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model that requires the use of forward-looking information to calculate credit loss estimates. It also eliminates the concept of other-than-temporary impairment and requires credit losses on available-for-sale debt securities to be recorded through an allowance for credit losses instead of as a reduction in the amortized cost basis of the securities. ASU 2016-13 was effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2019. Early adoption was permitted, including adoption in any interim period. In February 2020, the FASB issued ASU 2020-02, Financial Instruments-Credit Losses (Topic 326) and Leases (Topic 842) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842), which amended the effective date of the original pronouncement for smaller reporting companies. ASC 2016-13 and its amendments will be effective for annual and interim periods beginning after December 15, 2022 for smaller reporting companies. The Company is currently assessing the impact the adoption of this new standard will have on its consolidated financial statements and related disclosures.

The Company adopted ASU 2016-2, Leases, (Topic 842) as of April 1, 2019 on a modified retrospective basis and did not restate comparative periods as permitted under the transition guidance. The Company elected the practical expedient not to apply the recognition and measurement guidance of Topic 842 to short-term leases.
