Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization and Description of Business | Organization and Description of Business Mirum Pharmaceuticals, Inc. (the “Company”) was incorporated in the State of Delaware on May 2, 2018, and is headquartered in Foster City, California. The Company is a biopharmaceutical company dedicated to transforming the treatment of rare diseases affecting children and adults. The Company has three approved medicines: LIVMARLI® (maralixibat) oral solution (“Livmarli”), Cholbam® (cholic acid) capsules (“Cholbam”), and Chenodal® (chenodiol) tablets (“Chenodal”). Livmarli is approved for the treatment of cholestatic pruritus in patients with Alagille syndrome (“ALGS”) three months of age and older and cholestatic pruritus in patients with primary familial intrahepatic cholestasis (“PFIC”) five years of age and older in the United States and for the treatment of cholestatic pruritus in patients with ALGS two months of age and older in Europe. On August 31, 2023, the Company completed the acquisition of assets of Travere Therapeutics, Inc. (“Travere”) that are primarily related to the development, manufacture (including synthesis, formulation, finishing or packaging) and commercialization of Chenodal and Cholbam (also known as Kolbam, and together with Chenodal, the “Bile Acid Medicines”), two therapies addressing rare diseases in high-need settings (such acquisition, the “Bile Acid Portfolio Acquisition”) (Note 7). Cholbam is FDA-approved for the treatment of bile acid synthesis disorders due to single enzyme deficiencies and adjunctive treatment of peroxisomal disorders in patients who show signs or symptoms or liver disease. Chenodal is approved for the treatment of radiolucent stones in the gallbladder and has received medical necessity recognition by the FDA for the treatment of cerebrotendinous xanthomatosis (“CTX”). The Company’s development pipeline consists of the clinical-stage product candidate volixibat and life-cycle extension opportunities for Livmarli. The Company commenced significant operations in November 2018. The Company views its operations and manages its business as one operating segment. The Company determined its operating segment on the same basis that it uses to evaluate its performance internally. Liquidity The Company has a limited operating history, has incurred significant operating losses since its inception, and the revenue and income potential of the Company’s business and market are unproven. As of March 31, 2024, the Company had an accumulated deficit of $581.5 million and cash and cash equivalents of $302.8 million. The Company believes that its cash and cash equivalents of $302.8 million as of March 31, 2024, provide sufficient capital resources to continue its operations for at least twelve months from the issuance date of the accompanying unaudited condensed consolidated financial statements. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The unaudited interim financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results for the periods presented. All such adjustments are of a normal and recurring nature. The unaudited condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited consolidated financial statements at that date but does not include all information and footnotes required by GAAP for complete financial statements. The operating results presented in these unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for any future periods. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto in the Company’s Annual Report on Form 10-K (“Annual Report”) for the fiscal year ended December 31, 2023, as filed with the SEC on March 15, 2024. Statement of Cash Flows Reclassification Subsequent to the initial filing of the Company’s Quarterly Report on Form 10-Q for the three-month period ended March 31, 2023, the Company identified an immaterial error in the unaudited condensed consolidated statement of cash flows related to the classification of a $15.0 million milestone payment made to Shire International GmBH relating to our Assignment and License Agreement with them. This payment was presented as part of net cash used in operating activities but should have been classified within cash provided by investing activities. The misclassification did not impact the unaudited condensed consolidated balance sheet as of March 31, 2023, nor did it impact the unaudited condensed consolidated statements of operations, comprehensive loss and stockholders’ equity for the three months ended March 31, 2023. The Company concluded this misclassification was not material to the prior period considering both quantitative and qualitative factors as determined by authoritative guidance. The Company has revised the presentation and appropriately classified the payment within investing activities in the unaudited condensed consolidated statement of cash flows for the three-month period ended March 31, 2023, presented within this Quarterly Report on Form 10-Q. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in the financial statements and accompanying notes. These estimates and assumptions are based upon historical experience, knowledge of current events and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results could differ materially from those estimates. The Company’s unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2024 reflect the Company’s estimates of the impact of the geopolitical and macroeconomic environment, including the impact of inflation, bank failures, high interest rates and foreign exchange rate fluctuations. The duration and the scope of these conditions cannot be predicted; therefore, the extent to which these conditions will directly or indirectly impact the Company’s business, results of operations and financial condition, is uncertain. 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 the date of this filing. Significant Accounting Policies There have been no significant changes to the accounting policies during the three months ended March 31, 2024, as compared to the significant accounting policies described in Note 2 of the “Notes to Consolidated Financial Statements” in the Company’s audited consolidated financial statements included in the Annual Report, unless indicated below. Cash, Cash Equivalents and Restricted Cash Equivalents The Company considers all highly liquid investments that are readily convertible into cash without penalty and with original maturities of three months or less at the date of purchase to be cash equivalents. The carrying amounts reported in the unaudited condensed consolidated balance sheets for cash and cash equivalents are valued at cost, which approximate their fair value. Restricted cash equivalents as of March 31, 2023 consisted of deposits placed in a segregated bank account as required under the terms of the Company’s Revenue Interest Purchase Agreement (“RIPA”), as amended September 2021 and March 2022, with Mulholland SA LLC, an affiliate of Oberland Capital LLC, as agent for the purchasers party thereto (the “Purchasers”), and the Purchasers in connection with the sale of the Priority Review Voucher in December 2022. Upon repurchase and the termination of the RIPA in April 2023, in accordance with its terms, the previously restricted cash equivalents of $100.0 million were no longer restricted from use. The following table provides a reconciliation of cash, cash equivalents and restricted cash equivalents reported within the unaudited condensed consolidated balance sheets that together reflect the same amounts shown in the unaudited condensed consolidated statements of cash flows (in thousands): As of March 31, 2024 2023 Cash and cash equivalents $ 302,843 $ 49,419 Restricted cash equivalents — 100,000 Total cash, cash equivalents, and restricted cash equivalents $ 302,843 $ 149,419 Investments The Company classifies all investments in securities as available-for-sale. Management determines the appropriate classification of its investments in securities at the time of purchase. Investments with original maturities beyond three months at the date of purchase and which mature at, or less than twelve months from the balance sheet date, are classified as a current asset. Investments are recorded at fair value, with unrealized gains and losses reported as accumulated other comprehensive income (loss) until realized, with the exception of any declines in fair value below the cost basis that are a result of a credit loss, which, if any, are reported in other income (expense), net in the current period through an allowance for credit losses. Each reporting period, the Company evaluates whether declines in fair values of its available-for-sale securities below their cost basis are a result of credit loss or other factors and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. This evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss, the creditworthiness of the security issuers, as well as the Company’s ability and intent to hold the available-for-sale security until a forecasted recovery occurs. Additionally, the Company assesses whether it has plans to sell the security or it is more likely than not it will be required to sell any available-for-sale securities before recovery of its amortized cost basis. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion, as well as interest and dividends, are included in interest income. Realized gains and losses from the sale of available-for-sale securities, if any, are determined on a specific identification basis and are also included in Other income (expense). To date, the Company has not identified any declines in fair value of its investments related to credit loss. Concentrations of Credit Risk and Off-Balance Sheet Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents, accounts receivable and investments. The Company limits the amount of credit exposure by investing cash that is not required for immediate operating needs in money market funds, government obligations and/or commercial paper with short maturities. Additionally, the Company has established guidelines regarding diversification of its investments and their maturities, which are designed to maintain principal and maximize liquidity. To date, the Company has not experienced any losses associated with this credit risk and continues to believe that this exposure is not significant. The Company relies on a single distributor and a specialty pharmacy for all of the Company’s sales of its approved medicines in the United States as well as a single distributor for sales of Livmarli outside the United States. The Company sources materials and services through several vendors. Certain materials are sourced from a single vendor. The loss of certain vendors could result in a temporary disruption of the Company’s commercialization efforts. As of March 31, 2024 and as of December 31, 2023, the Company did not have any customers that individually accounted for more than 10% of accounts receivable. For the three months ended March 31, 2024 and 2023, the Company did not have revenue attributable to any one customer in excess of 10% of sales. Accounts Receivable The Company has accounts receivable amounts due from product sales. The Company also has accounts receivable amounts due from license agreements for milestones achieved, but not yet paid. Amounts payable to the Company are recorded as accounts receivable when the Company’s right to consideration is unconditional. The Company estimates the allowance for credit losses using the current expected credit loss model. Under this model, the allowance for credit losses reflects the Company’s estimate of lifetime expected credit losses. The Company evaluates the collectability of the cash flows based on the risk of loss over the contractual life, even when that risk is remote, based on judgments about the creditworthiness of its customers, historical experience and other relevant information that is available to the Company. There was no allowance for credit losses as of March 31, 2024. There was no bad debt expense for the three months ended March 31, 2024 and 2023. Inventory Inventory is valued at the lower of cost or net realizable value, with cost determined on a first-in, first-out (FIFO) basis. The Company periodically reviews the composition of inventory to identify excess, obsolete, slow-moving or otherwise unsaleable items. If unsaleable items are observed and there are no alternate uses for the inventory, the Company will record a write-down to net realizable value in the period that the decline in value is recognized through a charge to cost of sales. Furthermore, the Company periodically reviews its firm commitments for the purchase of minimum order quantities. If the minimum order quantities exceed the Company’s future demand, a net loss is accrued in cost of sales for such future inventory purchases. The determination of whether inventory costs will be realizable requires estimates by management. If actual market conditions are less favorable than projected by management, additional write-downs of inventory may be required. Accruals for firm purchase commitments amounted to $5.3 million and $5.2 million as of March 31, 2024 and December 31, 2023, respectively, of which $3.9 million and $3.8 million was included in other liabilities on the unaudited condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023, respectively. Intangible Assets, Net The Company accounts for asset acquisitions that do not meet the definition of a business using the cost accumulation method, whereby the cost of the acquisition, including certain transaction costs, is allocated to the asset (or assets) acquired on the basis of its (or their) relative fair value(s) on the measurement date. No goodwill is recognized in an asset acquisition. Intangible assets are measured at their fair values as of the acquisition date or, in the case of commercial milestone payments, the date they become due. The evaluation of intangible assets includes assessing the amortization period for which the asset is expected to contribute to the future cash flows of the Company. Intangible assets with finite useful lives are amortized over their estimated useful lives, primarily on a straight-line basis when the Company is unable to reliably estimate the pattern of cash flow. The Company tests its finite lived intangible assets for impairment annually or if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. If it is determined that the asset is impaired, the carrying value is written down to its estimated fair value, with the related impairment charge recognized in the unaudited condensed consolidated statements of operations in the period in which the impairment occurs. The Company has not recorded any impairments to its intangible assets for any of the periods presented.

Amortization expense was included in cost of sales in the accompanying unaudited condensed consolidated statements of operations. The following table summarizes the estimated future amortization expense associated with the Company’s intangible assets as of March 31, 2024 (in thousands): Amount 2024 (remaining nine months) 17,023 2025 22,698 2026 22,590 2027 22,375 2028 22,375 Thereafter 150,382 $ 257,443 Product Sales, Net The Company recognizes product sales, net when the customer obtains control of our product, which occurs at a point in time, typically upon delivery of the Company’s product to the customer. Revenues from product sales are recorded at the net sales price, or the transaction price, which may include fixed or variable consideration for discounts, government rebates, co-pay assistance, returns and other allowances that are offered within contracts with a customer relating to the sale of the Company's approved medicines. Estimates of variable consideration are calculated based on the actual product sales each reporting period and the nature of the variable consideration related to those sales. Overall, these estimates reflect the Company’s best estimate of the amount of consideration to which the Company expects to be entitled based on the terms of the contract. The amount of variable consideration that is included in the transaction price may be constrained and is included in product sales, net only to the extent that it is considered probable that a significant reversal in the amount of the cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Estimates are reviewed and updated quarterly as additional information becomes known. Actual amounts of consideration ultimately received may differ materially from estimates. If actual results in the future vary from estimates, the Company will adjust these estimates, which would affect product sales, net and earnings in the period such variances are adjusted. Significant categories of sales discounts and allowances are as follows: Government Rebates : The Company records rebates payable under Medicaid and other government programs as a reduction of revenue at the time product revenues are generated. The Company’s rebate calculations may require estimates, including estimates of customer mix, to determine which sales will be subject to rebates and the amount of such rebates. The Company updates its estimates and assumptions on a quarterly basis and records any necessary adjustments to revenue in the period identified. The liability for unpaid rebates is included in accrued expenses on the accompanying unaudited condensed consolidated balance sheets. To date, actual government rebates have not differed materially from the Company’s estimates. Other Incentives : Other incentives include a branded co-pay assistance program for eligible patients with commercial insurance in the United States. The branded co-pay assistance program assists commercially insured patients who have coverage for the Company's approved medicines and is intended to reduce each participating patient’s portion of the financial responsibility of the purchase price up to a specified dollar amount of assistance. The calculation of the accrual for co-pay assistance is based upon an identification of claims and the cost per claims associated with product that has been recognized as revenue. The Company records amounts paid under the brand specific co-pay assistance program for each patient as a reduction of revenue from product sales. To date, actual other incentives have not differed materially from the Company’s estimates. Product Returns : The Company records revenue for product sales, net of estimated product returns. Customers have limited return rights related only to the product’s damage or defect identified upon delivery of the product. The Company estimates the amount of product sales that may be returned and records the estimate as a reduction of revenue and a refund liability in the period the related product revenue is recognized. To date, actual returns have not differed materially from the Company’s estimates. The following table represents Total revenues and disaggregates Product sales, net by approved medicine (in thousands): Three Months Ended March 31, 2024 2023 Product sales, net: Livmarli $ 42,845 $ 29,098 Bile Acid Medicines 26,072 — Total product sales, net 68,917 29,098 License and other revenue 305 2,500 Total revenues $ 69,222 $ 31,598 The following table sets forth Product sales, net by geographic area based on the ship-to location (in thousands): Three Months Ended March 31, 2024 2023 United States $ 56,111 $ 24,614 Rest of the world 12,806 4,484 Total product sales, net $ 68,917 $ 29,098 Foreign Currency The unaudited condensed consolidated financial statements are presented in U.S. dollars. The functional currency for most of the Company’s foreign subsidiaries is their local currency. Balance sheet accounts of international subsidiaries are translated at the current exchange rates as of the end of each accounting period. Income statement items are translated at average exchange rates for the period. The resulting translation adjustments are recorded as a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included in other income (expense), net in the unaudited condensed consolidated statements of operations. Transaction gains and losses result primarily from fluctuations in exchange rates when intercompany receivables and payables are denominated in currencies other than the functional currency of our subsidiary that recorded the transaction. Unrealized foreign exchange gains amounted to $1.7 million for the three months ended March 31, 2024 and were insignificant for the three months ended March 31, 2023. Realized foreign exchange gains and losses were insignificant for the three months ended March 31, 2024 and 2023, respectively. Net Loss Per Share Basic net loss per share is computed by dividing net loss by the weighted-average shares of common stock outstanding for the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average shares of common stock and potentially dilutive securities outstanding for the period determined using the treasury-stock and if-converted methods. Diluted net loss per share excludes the potential impact of the Company’s common stock subject to repurchase, common stock options, restricted stock units, contingently issuable employee stock purchase plan shares and common stock issuable upon conversion of convertible notes because their effect would be anti-dilutive due to the Company’s net loss. Basic and diluted net loss per share were the same for the three months ended March 31, 2024 and 2023. The following outstanding potential dilutive shares have been excluded from the calculation of diluted net loss per share for the periods presented due to their anti-dilutive effect: As of March 31, As of March 31, 2024 2023 Options to purchase common stock and restricted stock units 12,525,389 10,573,024 Common stock issuable upon conversion of convertible notes 9,964,247 — Employee stock purchase plan contingently issuable 48,297 66,658 Shares issuable as contingent consideration in connection with asset acquisition — 31,638 Total 22,537,933 10,671,320 Recent Accounting Pronouncements Not Yet Adopted From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on the accompanying unaudited condensed consolidated financial statements and disclosures. In November 2023, the FASB issued ASU No. 2023-07, Improvements to Reportable Segment Disclosures (“ASU 2023-07”). This new guidance is designed to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). This new guidance is designed to enhance the transparency and decision usefulness of income tax disclosures. The amendments of this update are related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements. |

The Company paid $210.4 million upon closing of the transaction, and up to an additional $235.0 million is payable upon the achievement of certain milestones based on specified amounts of annual net sales of the Bile Acid Medicines. The Company accounted for the transaction as an asset acquisition as substantially all the fair value of the gross assets acquired was concentrated in a group of similar identifiable assets, namely, the developed technology related to the Bile Acid Medicines. The developed technology asset consists of certain processes and at-market contracts related to the manufacture and commercialization of the Bile Acid Medicines, regulatory approvals, and other assets, and are considered a single asset as they are interdependently linked. The Company is obligated to pay tiered royalties, based on licensing agreements acquired with the Bile Acid Medicines, with rates ranging from high single digit to mid-teens based on net sales of the Bile Acid Medicines. Assignment and License Agreement with Shire International GmbH (Takeda) In November 2018, the Company entered into an Assignment and License Agreement (the “Shire Agreement”) with Shire International GmbH (“Shire”), which was subsequently acquired by Takeda Pharmaceutical Company Limited (“Takeda”). Under the terms of the Shire Agreement, Shire granted the Company an exclusive, royalty bearing worldwide license to develop and commercialize its two product candidates, Livmarli and volixibat. As part of the Shire Agreement, the Company was assigned license agreements held by Shire with Satiogen Pharmaceuticals, Inc. (“Satiogen”), Pfizer Inc. (“Pfizer”) and Sanofi-Aventis Deutschland GmbH (“Sanofi”). The Company has the right to sublicense under the Shire Agreement and additionally has the right to sublicense under the Satiogen, Pfizer and Sanofi licenses subject to the terms of those license agreements. The Company is obligated to pay Shire up to an aggregate of $109.5 million upon the achievement of certain clinical development and regulatory milestones for Livmarli in certain indications and an additional $25.0 million upon regulatory approval of Livmarli for each and every other indication. In addition, the Company is required to pay up to an aggregate of $30.0 million upon the achievement of certain clinical development and regulatory milestones for volixibat solely for the first indication sought. Upon commercialization, the Company is obligated to pay Shire product sales milestones on total licensed products up to an aggregate of $30.0 million. The Company is also obligated to pay tiered royalties with rates ranging from low double-digits to mid-teens based upon annual worldwide net sales for all licensed products; however, these royalties are reduced in part by royalties due under the Satiogen and Sanofi licenses, as discussed below, related to Livmarli and volixibat, as applicable. The Company’s royalty obligations will continue on a licensed product-by-licensed product and country-by-country basis until the later to occur of the expiration of the last valid claim in a licensed patent covering the applicable licensed product in such country, expiration of any regulatory exclusivity for the licensed product in a country and ten years after the first commercial sale of a licensed product in such country. In January 2023, the Company paid the accrued regulatory milestone of $15.0 million associated with approval of Livmarli by the European Commission for the treatment of cholestatic pruritus in patients with ALGS two months of age and older.

The purchase consideration also included issuance of up to an additional 199,993 shares of the Company’s common stock, contingent upon the achievement of a certain milestone by June 30, 2025. In December 2022, with the approval of Livmarli by the European Commission for the treatment of cholestatic pruritus in patients with ALGS two months of age and older, the milestone was achieved and the Company issued 199,993 shares of common stock in January 2023.

Upon commercialization of any product utilizing the licensed product, the Company will be required to pay to Pfizer a low single-digit royalty on net sales of product sold by the Company, its affiliates or sublicensees. The Company’s royalty obligations continue on a licensed product-by-licensed product basis until the eighth anniversary of the first commercial sale of such licensed product anywhere in the world. Sanofi License Through the Shire Agreement, the Company was assigned a license agreement with Sanofi pursuant to which the Company obtained an exclusive, worldwide license to certain patents and know-how with the right to sublicense to a third party subject to certain financial considerations.

Additionally, upon commercialization, the Company is required to pay tiered royalties in the mid to high single-digit range based upon net sales of licensed products sold by the Company and sublicensees in a calendar year, subject to adjustments in certain circumstances. The Company’s royalty obligations continue on a licensed product-by-licensed product and country-by-country basis until the later to occur of the expiration of the last valid claim in a licensed patent covering the applicable licensed product in such country and ten years after the first commercial sale of a licensed product in such country. Royalty obligations under the Sanofi license are creditable against the royalty obligations to Shire under the Shire Agreement.

The net proceeds to the Company for the three months ended March 31, 2023, after deducting sales commissions to Leerink and other issuance expenses were approximately $14.5 million. The Company has issued and sold an aggregate of 2,125,090 shares of common stock pursuant to the 2020 Sales Agreement resulting in aggregate gross proceeds to the Company of $43.7 million. The 2020 Shelf Registration expired in August 2023, and no further sales may be made under the 2020 Sales Agreement. On September 9, 2022, the Company filed an automatic shelf registration statement on Form S-3 with the SEC (the “2022 Shelf Registration”), which became effective upon filing, pursuant to which the Company registered for sale from time to time in one or more offerings an unlimited amount of any combination of the Company’s common stock, preferred stock, debt securities and warrants, so long as the Company continues to satisfy the requirements of a “well-known seasoned issuer” under SEC rules. This automatic shelf registration statement will remain in effect for up to three years from the date it became effective. As of March 31, 2024, the Company had not issued any securities pursuant to the automatic shelf registration statement. On August 31, 2023, in connection with and immediately prior to the closing of the Bile Acid Portfolio Acquisition, the Company completed the private placement of 8,000,000 shares of the Company’s common stock at a price per share of $26.25, resulting in net proceeds of approximately $202.2 million, which the Company used to finance the upfront payment at the closing of the Bile Acid Portfolio Acquisition. On November 2, 2023, the Company entered into a Sales Agreement (the “2023 Sales Agreement”) with Leerink and Cantor Fitzgerald & Co. (the “Sales Agents”), pursuant to which the Company may, from time to time, sell up to an aggregate amount of $200.0 million of its common stock through the Sales Agents in an “at-the-market” offering (the “ATM Offering”). The Company is not required to sell shares under the 2023 Sales Agreement. Sales of the Company’s common stock, if any, under the 2023 Sales Agreement may be made in any transactions that are deemed to be “at the market offerings” as defined in Rule 415 under the Securities Act. The Company will pay a given designated Sales Agent a commission of up to 3.0% of the aggregate gross proceeds of any shares of common stock sold through such Sales Agent pursuant to the 2023 Sales Agreement. As of March 31, 2024, the Company had not issued any securities pursuant to the 2023 Sales Agreement. Common Stock Reserved for Issuance Common stock reserved for issuance is as follows: As of March 31, As of December 31, Stock options, restricted stock units and performance stock units issued and outstanding 12,525,389 10,909,831 Reserved for future stock awards or option grants 2,612,900 2,230,264 Reserved for employee stock purchase plan 1,508,059 1,040,828 Common stock issuable upon conversion of convertible notes 9,964,247 9,964,247 26,610,595 24,145,170 |

Share-Based Payment Arrangement [Abstract] | |
Stock-Based Compensation | Stock-Based Compensation Equity Incentive Plans In November 2018, the Company adopted the 2018 Equity Incentive Plan (the “2018 Plan”), which permits the granting of stock awards and incentive and nonstatutory stock options to employees, directors and consultants of the Company. In July 2019, the Company’s board of directors and stockholders approved and adopted the 2019 Equity Incentive Plan (the “2019 Plan”). The 2019 Plan became effective on July 17, 2019. Under the 2019 Plan, the Company may grant stock options, stock appreciation rights, restricted stock, restricted stock units and other stock or cash-based awards to individuals who are then employees, officers, directors or consultants of the Company. Shares subject to outstanding awards under the 2018 Plan as of the effective date of the 2019 Plan that are subsequently canceled, forfeited or repurchased by the Company will be added to the shares reserved under the 2019 Plan. In addition, the number of shares of common stock available for issuance under the 2019 Plan will be automatically increased on the first day of each calendar year during the ten-year term of the 2019 Plan, beginning with January 1, 2020 and ending with January 1, 2029, by an amount equal to 5% of the outstanding number of shares of the Company’s common stock on December 31st of the preceding calendar year or such lesser amount as determined by the Company’s board of directors. As of March 31, 2024, 1,721,899 shares of common stock were available for issuance under the 2019 Plan. In March 2020, the compensation committee of the Company’s board of directors approved and adopted the 2020 Inducement Plan (the “2020 Inducement Plan”). Under the 2020 Inducement Plan, the Company may grant nonstatutory stock options, stock appreciation rights, restricted stock and restricted stock units to new employees entering into employment with the Company in accordance with Nasdaq Listing Rule 5635(c)(4). At adoption, the 2020 Inducement Plan authorized 750,000 shares of the Company’s common stock for future issuance. Through March 31, 2024, the Company’s board of directors authorized an additional 3,250,000 shares of the Company’s common stock for future issuance. As of March 31, 2024, 891,001 shares of common stock were available for issuance under the 2020 Inducement Plan. Stock Options The following table summarizes stock option activity during the three months ended March 31, 2024 (in thousands, except share and per share data): Number of Awards Weighted- Average Exercise Price Weighted- Average Remaining Contractual Life (in Years) Aggregate Intrinsic Value Outstanding as of December 31, 2023 9,632,504 $ 15.87 6.9 $ 131,785 Granted 1,414,439 $ 26.56 Exercised (73,309) $ 16.31 Canceled and forfeited (139,901) $ 22.44 Outstanding as of March 31, 2024 10,833,733 $ 17.18 7.0 $ 90,813 Vested and exercisable as of March 31, 2024 6,523,254 $ 12.90 5.8 $ 79,722 Intrinsic value is calculated as the difference between the exercise price of the underlying options and the fair value of the common stock for the options that had exercise prices that were lower than the per share fair value of the common stock on the date of exercise. The weighted-average grant date fair value per share of stock options granted during the three months ended March 31, 2024 and 2023 was $19.01 and $16.81 per share, respectively. The total intrinsic value of options exercised during the three months ended March 31, 2024 and 2023 was $0.7 million and $0.5 million, respectively. As of March 31, 2024, the total unrecognized stock-based compensation related to unvested stock option awards granted was $66.0 million, which the Company expects to recognize over a weighted-average period of approximately 2.9 years. The fair value of each employee and non-employee stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. Due to the Company’s limited operating history and a lack of company specific historical and implied volatility data, the expected stock price volatility was based upon the weighting of the Company’s historical volatility and the historical volatility of a peer group of publicly traded companies. The historical volatility data was computed using the daily closing prices for the Company’s and its peer companies’ shares during the equivalent period of the calculated expected term of the stock-based awards. Due to the lack of historical exercise history, the expected term of the Company’s stock options for employees has been determined utilizing the “simplified” method for awards. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is zero based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. The following assumptions were used to estimate the fair value of stock option awards granted during the following periods: Three Months Ended March 31, 2024 2023 Expected term (in years) 6.08 5.31-6.08 Expected volatility 78.21% - 80.36% 81.83%-85.24% Risk-free interest rate 3.82% - 4.16% 3.61%-3.91% Expected dividend yield — — Restricted Stock Units The following table summarizes the activity under the Company’s restricted stock units for the three months ended March 31, 2024: Number of Weighted-Average Grant Date Unvested and outstanding as of December 31, 2023 1,129,492 $ 23.41 Granted 576,495 $ 26.58 Vested (261,009) $ 20.46 Cancelled/Forfeited (53,407) $ 24.39 Unvested and outstanding as of March 31, 2024 1,391,571 $ 25.24 The fair value of restricted stock unit awards granted to employees and nonemployees is equal to the closing market price of the Company’s common stock on the grant date. As of March 31, 2024, the total unrecognized stock-based compensation related to restricted stock unit awards granted was $30.4 million, which the Company expects to recognize over a weighted-average period of approximately 2.1 years. Performance Stock Units In January 2023, the Company granted an aggregate of 135,835 performance stock units to certain executive participants (“2023 Executive PSUs”). The 2023 Executive PSUs are subject to a performance condition of achieving certain net product sales levels related to Livmarli during the year ended December 31, 2024. If the performance condition is met, the first tranche of the award will vest on March 15, 2025 and the second tranche will vest on March 15, 2026, subject to the executive employees’ continuous service through each vesting date. The number of units to be vested in the first tranche of the 2023 Executive PSUs is calculated by multiplying two-thirds of the 2023 Executive PSUs granted by a percentage calculated based on attained Livmarli sales metrics, as certified by the Company’s Compensation Committee. The number of units to be vested in the second tranche of the 2023 Executive PSUs equals 50% of the units vested in the first tranche. In June 2023, the Company granted an aggregate of 12,000 PSUs to certain employees (“2023 Employee PSUs”). The 2023 Employee PSUs are subject to a performance condition of achieving certain net product sales related to Livmarli in the US for the year ended December 31, 2023. The first tranche of the 2023 Employee PSUs vested during the three months ended March 31, 2024. In January 2024, the Company granted an aggregate of 148,250 performance stock units to certain executive participants (“2024 Executive PSUs”). The 2024 Executive PSUs are subject to a performance condition of achieving certain net product sales levels related to the Company’s approved medicines during the year ended December 31, 2025. If the performance condition is met, the first tranche of the award will vest on March 15, 2026 and the second tranche will vest on March 15, 2027, subject to the executive employees’ continuous service through each vesting date. The number of units to be vested in the first tranche of the 2024 Executive PSUs is calculated by multiplying two-thirds of the 2024 Executive PSUs granted by a percentage calculated based on attained sales metrics for the Company’s approved medicines, as certified by the Company’s Compensation Committee. The number of units to be vested in the second tranche of the 2024 Executive PSUs equals 50% of the units vested in the first tranche. The following table summarizes the activity under the Company's performance stock units for the three months ended March 31, 2024: Number of Weighted-Average Grant Date Unvested and outstanding as of December 31, 2023 147,835 $ 23.64 Granted 160,250 $ 26.49 Vested (3,645) $ 25.39 Cancelled/Forfeited (4,355) $ 25.39 Unvested and outstanding as of March 31, 2024 300,085 $ 25.11 As of March 31, 2024, the total unrecognized stock compensation related to performance stock units granted was $6.7 million, which the Company expects to recognize over a weighted-average period of approximately 2.0 years. 2019 Employee Stock Purchase Plan In July 2019, the Company’s board of directors and stockholders approved and adopted the 2019 Employee Stock Purchase Plan (“ESPP”). A total of 500,000 shares of common stock were approved to be initially reserved for issuance under the ESPP. In addition, the number of shares of common stock available for issuance under the ESPP will be automatically increased on the first day of each calendar year during the first ten years of the term of the ESPP, beginning with January 1, 2020 and ending with January 1, 2029, by an amount equal to the lesser of (i) 1% of the outstanding number of shares of common stock on December 31st of the preceding calendar year, (ii) 1,500,000 shares of common stock or (iii) such lesser amount as determined by the Company’s board of directors. The ESPP became effective on July 17, 2019 and generally provides for six-month consecutive offering periods beginning on May 11th and November 11th of each year. During the three months ended March 31, 2024, no shares were issued under the ESPP. As of March 31, 2024, the Company had 1,508,059 shares available for future issuance under the ESPP. The stock-based compensation related to the ESPP was $0.3 million for each of the three months ended March 31, 2024 and 2023. Compensation Expense Total stock-based compensation is reflected in the accompanying unaudited condensed consolidated statements of operations as follows (in thousands): Three Months Ended March 31, 2024 2023 Selling, general and administrative $ 7,589 $ 5,846 Research and development 3,861 2,715 Total $ 11,450 $ 8,561 Stock-based compensation capitalized into inventory was $0.2 million for each of the three months ended March 31, 2024 and 2023. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Certain of the Company's contractual arrangements with contract manufacturing organizations require binding forecasts or commitments to purchase minimum amounts for the manufacture of drug product supply, which may be material to the Company's unaudited condensed financial statements. The Company is subject to potential liabilities under government regulations and various claims and legal actions that are pending or may be asserted from time-to-time. These matters arise in the ordinary course and conduct of the Company’s business and may include, for example, commercial, intellectual property, and employment matters. The Company intends to defend itself vigorously in such matters and when warranted, take legal action against others. Furthermore, the Company regularly assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its unaudited condensed consolidated financial statements. An estimated loss contingency is accrued in the Company’s unaudited condensed consolidated financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Company does not accrue amounts for liabilities that it does not believe are probable. Litigation is inherently unpredictable, and unfavorable resolutions could occur. As a result, assessing contingencies is highly subjective and requires judgment about future events. During the periods presented, the Company has not recorded any accrual for loss contingencies associated with such government regulations, claims or legal actions, determined that an unfavorable outcome is probable or reasonably possible, or determined that the amount or range of any possible loss is reasonably estimable. |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. The unaudited interim financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results for the periods presented. All such adjustments are of a normal and recurring nature. The unaudited condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited consolidated financial statements at that date but does not include all information and footnotes required by GAAP for complete financial statements. The operating results presented in these unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for any future periods. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto in the Company’s Annual Report on Form 10-K (“Annual Report”) for the fiscal year ended December 31, 2023, as filed with the SEC on March 15, 2024. |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in the financial statements and accompanying notes. These estimates and assumptions are based upon historical experience, knowledge of current events and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results could differ materially from those estimates. The Company’s unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2024 reflect the Company’s estimates of the impact of the geopolitical and macroeconomic environment, including the impact of inflation, bank failures, high interest rates and foreign exchange rate fluctuations. The duration and the scope of these conditions cannot be predicted; therefore, the extent to which these conditions will directly or indirectly impact the Company’s business, results of operations and financial condition, is uncertain. 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 the date of this filing. |
Cash, Cash Equivalents and Restricted Cash Equivalents | Cash, Cash Equivalents and Restricted Cash Equivalents The Company considers all highly liquid investments that are readily convertible into cash without penalty and with original maturities of three months or less at the date of purchase to be cash equivalents. The carrying amounts reported in the unaudited condensed consolidated balance sheets for cash and cash equivalents are valued at cost, which approximate their fair value. Restricted cash equivalents as of March 31, 2023 consisted of deposits placed in a segregated bank account as required under the terms of the Company’s Revenue Interest Purchase Agreement (“RIPA”), as amended September 2021 and March 2022, with Mulholland SA LLC, an affiliate of Oberland Capital LLC, as agent for the purchasers party thereto (the “Purchasers”), and the Purchasers in connection with the sale of the Priority Review Voucher in December 2022. Upon repurchase and the termination of the RIPA in April 2023, in accordance with its terms, the previously restricted cash equivalents of $100.0 million were no longer restricted from use. |
Investments | Investments The Company classifies all investments in securities as available-for-sale. Management determines the appropriate classification of its investments in securities at the time of purchase. Investments with original maturities beyond three months at the date of purchase and which mature at, or less than twelve months from the balance sheet date, are classified as a current asset. Investments are recorded at fair value, with unrealized gains and losses reported as accumulated other comprehensive income (loss) until realized, with the exception of any declines in fair value below the cost basis that are a result of a credit loss, which, if any, are reported in other income (expense), net in the current period through an allowance for credit losses. Each reporting period, the Company evaluates whether declines in fair values of its available-for-sale securities below their cost basis are a result of credit loss or other factors and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. This evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss, the creditworthiness of the security issuers, as well as the Company’s ability and intent to hold the available-for-sale security until a forecasted recovery occurs. Additionally, the Company assesses whether it has plans to sell the security or it is more likely than not it will be required to sell any available-for-sale securities before recovery of its amortized cost basis. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion, as well as interest and dividends, are included in interest income. Realized gains and losses from the sale of available-for-sale securities, if any, are determined on a specific identification basis and are also included in Other income (expense). To date, the Company has not identified any declines in fair value of its investments related to credit loss. |
Concentrations of Credit Risk and Off-Balance Sheet Risk | Concentrations of Credit Risk and Off-Balance Sheet Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents, accounts receivable and investments. The Company limits the amount of credit exposure by investing cash that is not required for immediate operating needs in money market funds, government obligations and/or commercial paper with short maturities. Additionally, the Company has established guidelines regarding diversification of its investments and their maturities, which are designed to maintain principal and maximize liquidity. To date, the Company has not experienced any losses associated with this credit risk and continues to believe that this exposure is not significant. The Company relies on a single distributor and a specialty pharmacy for all of the Company’s sales of its approved medicines in the United States as well as a single distributor for sales of Livmarli outside the United States. The Company sources materials and services through several vendors. Certain materials are sourced from a single vendor. The loss of certain vendors could result in a temporary disruption of the Company’s commercialization efforts. As of March 31, 2024 and as of December 31, 2023, the Company did not have any customers that individually accounted for more than 10% of accounts receivable. For the three months ended March 31, 2024 and 2023, the Company did not have revenue attributable to any one customer in excess of 10% of sales. |
Accounts Receivable | Accounts Receivable The Company has accounts receivable amounts due from product sales. The Company also has accounts receivable amounts due from license agreements for milestones achieved, but not yet paid. Amounts payable to the Company are recorded as accounts receivable when the Company’s right to consideration is unconditional. The Company estimates the allowance for credit losses using the current expected credit loss model. Under this model, the allowance for credit losses reflects the Company’s estimate of lifetime expected credit losses. The Company evaluates the collectability of the cash flows based on the risk of loss over the contractual life, even when that risk is remote, based on judgments about the creditworthiness of its customers, historical experience and other relevant information that is available to the Company. There was no allowance for credit losses as of March 31, 2024. There was no bad debt expense for the three months ended March 31, 2024 and 2023. |
Inventory | Inventory Inventory is valued at the lower of cost or net realizable value, with cost determined on a first-in, first-out (FIFO) basis. The Company periodically reviews the composition of inventory to identify excess, obsolete, slow-moving or otherwise unsaleable items. If unsaleable items are observed and there are no alternate uses for the inventory, the Company will record a write-down to net realizable value in the period that the decline in value is recognized through a charge to cost of sales. Furthermore, the Company periodically reviews its firm commitments for the purchase of minimum order quantities. If the minimum order quantities exceed the Company’s future demand, a net loss is accrued in cost of sales for such future inventory purchases. The determination of whether inventory costs will be realizable requires estimates by management. If actual market conditions are less favorable than projected by management, additional write-downs of inventory may be required. |
Intangibles Assets, Net | Intangible Assets, Net The Company accounts for asset acquisitions that do not meet the definition of a business using the cost accumulation method, whereby the cost of the acquisition, including certain transaction costs, is allocated to the asset (or assets) acquired on the basis of its (or their) relative fair value(s) on the measurement date. No goodwill is recognized in an asset acquisition. Intangible assets are measured at their fair values as of the acquisition date or, in the case of commercial milestone payments, the date they become due. The evaluation of intangible assets includes assessing the amortization period for which the asset is expected to contribute to the future cash flows of the Company. Intangible assets with finite useful lives are amortized over their estimated useful lives, primarily on a straight-line basis when the Company is unable to reliably estimate the pattern of cash flow. The Company tests its finite lived intangible assets for impairment annually or if events or changes in circumstances indicate that it is more likely than not that the asset is impaired. If it is determined that the asset is impaired, the carrying value is written down to its estimated fair value, with the related impairment charge recognized in the unaudited condensed consolidated statements of operations in the period in which the impairment occurs. The Company has not recorded any impairments to its intangible assets for any of the periods presented. The components of the Company’s intangible assets were as follows (in thousands, except for weighted-average remaining amortization period): March 31, 2024 Gross Carrying Value Accumulated Amortization Net Carrying Amount Weighted-Average Remaining Amortization Period (Years) Commercial milestones $ 49,000 $ (3,968) $ 45,032 14.3 Developed technology 226,620 (14,991) 211,629 11.4 Assembled workforce 970 (188) 782 2.4 Total intangible assets $ 276,590 $ (19,147) $ 257,443 11.9 December 31, 2023 Gross Carrying Value Accumulated Amortization Net Carrying Amount Weighted-Average Remaining Amortization Period (Years) Commercial milestones $ 39,000 $ (3,318) $ 35,682 16.2 Developed technology 226,620 (10,239) 216,381 11.7 Assembled workforce 970 (108) 862 2.7 Total intangible assets $ 266,590 $ (13,665) $ 252,925 12.3 Amortization expense was $5.5 million and $1.3 million for the three months ended March 31, 2024 and 2023, respectively. Amortization expense was included in cost of sales in the accompanying unaudited condensed consolidated statements of operations. The following table summarizes the estimated future amortization expense associated with the Company’s intangible assets as of March 31, 2024 (in thousands): Amount 2024 (remaining nine months) 17,023 2025 22,698 2026 22,590 2027 22,375 2028 22,375 Thereafter 150,382 $ 257,443 |
Product Sales, Net | Product Sales, Net The Company recognizes product sales, net when the customer obtains control of our product, which occurs at a point in time, typically upon delivery of the Company’s product to the customer. Revenues from product sales are recorded at the net sales price, or the transaction price, which may include fixed or variable consideration for discounts, government rebates, co-pay assistance, returns and other allowances that are offered within contracts with a customer relating to the sale of the Company's approved medicines. Estimates of variable consideration are calculated based on the actual product sales each reporting period and the nature of the variable consideration related to those sales. Overall, these estimates reflect the Company’s best estimate of the amount of consideration to which the Company expects to be entitled based on the terms of the contract. The amount of variable consideration that is included in the transaction price may be constrained and is included in product sales, net only to the extent that it is considered probable that a significant reversal in the amount of the cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Estimates are reviewed and updated quarterly as additional information becomes known. Actual amounts of consideration ultimately received may differ materially from estimates. If actual results in the future vary from estimates, the Company will adjust these estimates, which would affect product sales, net and earnings in the period such variances are adjusted. Significant categories of sales discounts and allowances are as follows: Government Rebates : The Company records rebates payable under Medicaid and other government programs as a reduction of revenue at the time product revenues are generated. The Company’s rebate calculations may require estimates, including estimates of customer mix, to determine which sales will be subject to rebates and the amount of such rebates. The Company updates its estimates and assumptions on a quarterly basis and records any necessary adjustments to revenue in the period identified. The liability for unpaid rebates is included in accrued expenses on the accompanying unaudited condensed consolidated balance sheets. To date, actual government rebates have not differed materially from the Company’s estimates. Other Incentives : Other incentives include a branded co-pay assistance program for eligible patients with commercial insurance in the United States. The branded co-pay assistance program assists commercially insured patients who have coverage for the Company's approved medicines and is intended to reduce each participating patient’s portion of the financial responsibility of the purchase price up to a specified dollar amount of assistance. The calculation of the accrual for co-pay assistance is based upon an identification of claims and the cost per claims associated with product that has been recognized as revenue. The Company records amounts paid under the brand specific co-pay assistance program for each patient as a reduction of revenue from product sales. To date, actual other incentives have not differed materially from the Company’s estimates. Product Returns : The Company records revenue for product sales, net of estimated product returns. Customers have limited return rights related only to the product’s damage or defect identified upon delivery of the product. The Company estimates the amount of product sales that may be returned and records the estimate as a reduction of revenue and a refund liability in the period the related product revenue is recognized. To date, actual returns have not differed materially from the Company’s estimates. The following table represents Total revenues and disaggregates Product sales, net by approved medicine (in thousands): Three Months Ended March 31, 2024 2023 Product sales, net: Livmarli $ 42,845 $ 29,098 Bile Acid Medicines 26,072 — Total product sales, net 68,917 29,098 License and other revenue 305 2,500 Total revenues $ 69,222 $ 31,598 |
Foreign Currency | Foreign Currency The unaudited condensed consolidated financial statements are presented in U.S. dollars. The functional currency for most of the Company’s foreign subsidiaries is their local currency. Balance sheet accounts of international subsidiaries are translated at the current exchange rates as of the end of each accounting period. Income statement items are translated at average exchange rates for the period. The resulting translation adjustments are recorded as a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included in other income (expense), net in the unaudited condensed consolidated statements of operations. Transaction gains and losses result primarily from fluctuations in exchange rates when intercompany receivables and payables are denominated in currencies other than the functional currency of our subsidiary that recorded the transaction. Unrealized foreign exchange gains amounted to $1.7 million for the three months ended March 31, 2024 and were insignificant for the three months ended March 31, 2023. Realized foreign exchange gains and losses were insignificant for the three months ended March 31, 2024 and 2023, respectively. |
Net Loss Per Share | Net Loss Per Share Basic net loss per share is computed by dividing net loss by the weighted-average shares of common stock outstanding for the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average shares of common stock and potentially dilutive securities outstanding for the period determined using the treasury-stock and if-converted methods. Diluted net loss per share excludes the potential impact of the Company’s common stock subject to repurchase, common stock options, restricted stock units, contingently issuable employee stock purchase plan shares and common stock issuable upon conversion of convertible notes because their effect would be anti-dilutive due to the Company’s net loss. Basic and diluted net loss per share were the same for the three months ended March 31, 2024 and 2023. |
Recent Accounting Pronouncements Not Yet Adopted | Recent Accounting Pronouncements Not Yet Adopted From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on the accompanying unaudited condensed consolidated financial statements and disclosures. In November 2023, the FASB issued ASU No. 2023-07, Improvements to Reportable Segment Disclosures (“ASU 2023-07”). This new guidance is designed to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures (“ASU 2023-09”). This new guidance is designed to enhance the transparency and decision usefulness of income tax disclosures. The amendments of this update are related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements. |
