Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and related notes included in Item 8 “Financial Statements and Supplementary Data” and included elsewhere in this Annual Report. This discussion and analysis contains forward-looking statements based upon our current beliefs, estimates, plans and expectations that involve risks, uncertainties and assumptions. Our actual results may differ materially from those contained in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” or in other parts of this Annual Report.

Overview

We are a biopharmaceutical company focused on the identification, acquisition, development and commercialization of novel therapies for debilitating rare and orphan diseases. We have three approved medicines: Livmarli, Cholbam, and Chenodal.

Livmarli is a novel, orally administered, minimally-absorbed IBATi that is approved for the treatment of cholestatic pruritus in patients with ALGS in the United States and various other countries around the world and for cholestatic pruritus in patients with PFIC in the United States. We market and commercialize Livmarli in the United States and certain countries in Europe through our specialized and focused commercial team. We have also entered into license and distribution agreements with several rare disease companies for the commercialization of Livmarli in additional countries. We are also developing Livmarli for PFIC outside of the United States. We submitted a marketing authorization variation to the EMA in April 2023, for which we expect an approval decision in the first half of 2024, based on positive data from our MARCH Phase 3 clinical trial of Livmarli in patients with PFIC.

On August 31, 2023, we completed the acquisition of assets of Travere that are primarily related to the development, manufacture (including synthesis, formulation, finishing or packaging) and commercialization of the Bile Acid Medicines pursuant to an asset purchase agreement dated July 16, 2023. The FDA approved Cholbam in March 2015 as the first FDA-approved treatment for pediatric and adult patients with bile acid synthesis disorders due to single enzyme defects and for adjunctive treatment of patients with peroxisomal disorders, including PBD-ZSD and SLOS. 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 CTX. We commercialize Chenodal and Cholbam in the United States through our specialized and focused commercial team. We have also assumed several license and distribution agreements with several rare disease companies for the commercialization of Chenodal and Cholbam in additional countries. In October 2023, we reported positive topline data from our RESTORE clinical trial evaluating Chenodal in patients with CTX. We plan to submit a new drug application for Chenodal for the treatment of CTX to the FDA in the first half of 2024.

We are also advancing our product candidate, volixibat, a novel, oral, minimally-absorbed agent designed to inhibit IBAT, for the treatment of adult patients with cholestatic liver diseases. We are developing volixibat in the setting of PSC and PBC. Volixibat has been studied in over 400 adults for up to 48 weeks. Clinical trials of volixibat have shown significant activity on IBAT and bile acid markers such as 7αC4, fecal bile acids and cholesterol, demonstrating potent biological activity. We expect to conduct an interim analysis of our VISTAS Phase 2b clinical trial in PSC and report interim data from our VANTAGE Phase 2b clinical trial in PBC, both in the first half of 2024.

We were incorporated in May 2018 and commenced operations in November 2018. To date, we have focused primarily on acquiring and in-licensing our product candidates, organizing and staffing our company, business planning, raising capital, advancing our product candidates through clinical development, preparing for commercialization of our product candidates, commercializing Livmarli, and conducting business development activities relating to, among other things, portfolio expansion through collaborations and acquisitions.

We have not generated operating income to date. We expect to incur significant operating losses for the foreseeable future. Since inception, we have funded our operations primarily through debt, equity, revenue interest financings and cash from our product sales, net and collaboration revenue.

94

Financial Overview

Our net loss was $163.4 million and $135.7 million for the years ended December 31, 2023 and 2022, respectively. Our net loss for the year ended December 30, 2023 includes a $49.1 million loss related to the extinguishment of the liabilities related to the RIPA. As of 2023, we had an accumulated deficit of $556.2 million compared to $392.8 million as of December 31, 2022. As of December 31, 2023, we had cash and cash equivalents of $286.3 million, compared to cash, cash equivalents, restricted cash and investments of $251.7 million as of December 31, 2022.

We anticipate we will continue to generate losses for the foreseeable future as we continue commercial activities for our approved medicines, conduct our ongoing and planned clinical trials, seek regulatory approvals for our product candidates and make potential milestone payments to the licensors and other third parties from whom we have in-licensed or acquired our product candidates. We expect total product sales of our approved medicines will continue to increase on an annual basis, though we expect quarterly fluctuations. We have entered into collaboration arrangements with other companies whereby we are entitled to receive upfront and license fees, research and development funding, development and sales-based milestones, and tiered royalties based on sales of commercialized products. In select countries, we have entered into distribution agreements for the sale of Livmarli and such distributors may have fluctuating purchase levels of Livmarli. As a result, our net losses may fluctuate significantly from quarter-to-quarter and year-to-year.

We expect to satisfy future cash needs through existing capital balances, revenue from our approved medicines and through a combination of equity offerings, including the private placement described above, debt financings or other capital sources, collaborations, licenses and other similar arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements when needed could have a negative impact on our financial condition and on our ability to pursue our business plans and strategies. If we are unable to raise additional capital when needed, we could be forced to delay, limit, reduce or terminate the development of one or more of our product candidates or future commercialization efforts or grant rights to develop and market our product candidates even if we would otherwise prefer to develop and market such product candidates ourselves.

Geopolitical and Macroeconomic Developments

Due to the ongoing military conflicts between Ukraine and Russia and in Israel and the surrounding areas, the U.S. and global financial markets experienced volatility, which has led to disruptions to trade, commerce, pricing stability, credit availability and supply chain continuity globally. In connection with the military conflict between Russia and Ukraine, the United States, United Kingdom and EU, along with others, imposed significant new sanctions and export controls against Russia, Russian banks and certain Russian individuals and may implement additional sanctions or take further punitive actions in the future. The full economic and social impact of the sanctions imposed on Russia (as well as possible future punitive measures that may be implemented), as well as the counter measures imposed by Russia, in addition to the ongoing military conflict between Ukraine and Russia and related sanctions, which could conceivably expand into the surrounding region, remains uncertain; however, both the conflict and related sanctions have resulted and could continue to result in disruptions to trade, commerce, pricing stability, credit availability and supply chain continuity in both Europe and globally, and has introduced significant uncertainty into global markets. As a result, our business and results of operations may be adversely affected by the ongoing military conflicts and related sanctions, particularly to the extent it escalates to involve additional countries, further economic sanctions or wider military conflict.

Although we did not see a significant financial impact to our business operations as a result of recent geopolitical and macroeconomic developments, such as recent and potential future disruptions in access to bank deposits or lending commitments due to bank failures and the ongoing military conflicts for the year ended December 31, 2023, there may be potential impacts to our business in the future that are highly uncertain and difficult to predict such as disruptions or restrictions in our supply chain, disruption or restrictions on our employees’ ability to travel, disruptions to or delays in ongoing non-clinical trials, clinical trials, third-party manufacturing supply and other operations, inability for patients to see their healthcare providers and access our product and product candidates, or adverse geopolitical and macroeconomic concerns, interruptions or delays in the operations of the FDA or other regulatory authorities, continued increases in inflation and interest rates, bank

95

failures, changes in availability and cost of credit and our ability to raise capital and conduct business development activities. The ultimate impact of these geopolitical and macroeconomic developments, as well as any lasting effects on our revenue and the way we conduct our business, is highly uncertain and subject to continued change, and we recognize that they may continue to present unique challenges for us.

We believe that our existing cash and cash equivalents and existing sources of and access to financing are adequate to satisfy our needs for operating capital, working capital, capital expenditures, and debt service in the 12 months from the issuance of the consolidated financial statements included in this Annual Report. However, should adverse geopolitical and macroeconomic events and any associated recession or depression continue for a prolonged period, our results of operations, financial condition, liquidity and cash flows could be materially impacted as a result of a lower likelihood of effectively and efficiently developing new product candidates and successfully commercializing our approved medicines.

Asset Purchase Agreement with Travere Therapeutics, Inc.

On August 31, 2023, we completed the Bile Acid Portfolio Acquisition. We 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.

We concurrently entered into a transitional services agreement with Travere, pursuant to which Travere is obligated to perform certain services for a period of time, not anticipated to last beyond 12 months post-close, with respect to our use and operation of the assets purchased.

In connection with and immediately prior to the closing of the Bile Acid Portfolio Acquisition, we completed the private placement of 8,000,000 shares of our common stock at a price per share of $26.25, resulting in net proceeds of approximately $202.2 million.

Satiogen Acquisition

In May 2022, we completed the acquisition of Satiogen for total consideration of $24.2 million. At the closing of the acquisition, Satiogen’s assets consisted of cash and intangible assets related to developed technology. Through the transaction, we obtained all Satiogen-owned intellectual property relating to Livmarli and volixibat. The transaction resulted in a reduction of total licensing royalty obligations for Livmarli and volixibat.

The total potential consideration for the acquisition consisted of 841,792 shares of common stock and approximately $2.6 million in cash, excluding $0.2 million of stock option exercise prices deemed to have been paid immediately prior to the acquisition, in respect of an equivalent amount of cash on the books of Satiogen acquired by us at closing.

Assignment and License Agreement with Shire (Takeda)

In November 2018, we entered into the Shire License Agreement with Shire, which was subsequently acquired by Takeda, in which we were granted an exclusive, royalty bearing worldwide license to develop and commercialize our two product candidates, Livmarli and volixibat. As part of the Shire License Agreement, we were assigned license agreements held by Shire with Satiogen, Pfizer, and Sanofi (collectively, “Assigned License Agreements”).

Under the Shire License Agreement and Assigned License Agreements, to date, we have paid aggregate development regulatory and sales milestones of $71.0 million related to our Livmarli and volixibat programs.

Components of Results of Operations

Revenue

Product Sales, Net

We have three approved medicines: Livmarli, Cholbam and Chenodal. We expect total product sales of our approved medicines will continue to increase on an annual basis, though we expect quarterly fluctuations.

96

Our U.S. revenue from product sales, net further depends on our prescription mix of commercial payors, Medicaid and free medicines under our patient assistance program. We expect our prescription mix and resulting gross to net adjustment in the U.S. to remain consistent; however, we cannot reliably estimate it given our limited experience in the market. Our rest of world revenue from product sales, net primarily depends on our contractual obligations with our distributors and results of pricing negotiations with governmental authorities in certain European countries where we launch Livmarli and expect to launch our other product candidates, if approved. In addition, in certain countries, governments place large periodic orders. The timing of these orders can be inconsistent and can create quarter-to-quarter variation in revenue.

License Revenue

Under the exclusive licensing agreements with CANbridge and GC Biopharma, we have recognized as revenue the upfront nonrefundable payments related to the licenses granted upon satisfaction of certain performance obligations. Pursuant to the agreements, we are eligible to receive future milestone payments. These milestone payments are fully constrained and will be recognized in revenue in the period when it is probable that a significant reversal of cumulative revenue recognized for the contract would not occur. We are also eligible to receive royalty payments related to the agreements, which will be recognized as the underlying product sales occur.

Our license revenue is dependent upon our licensees’ achievement of future milestones, which are not within our control, and we are unable to reliably estimate the timing of such revenues.

Cost of Sales

Cost of sales consist of raw materials, third-party manufacturing costs, personnel, facility and other costs of manufacturing commercial products, transportation and freight, amortization of finite-lived intangible assets, amortization of capitalized intangibles and royalty payments payable on net sales of our approved medicines under licensing agreements. Cost of sales may also include period costs related to certain manufacturing services and charges for inventory valuation reserves.

As of the date of our acquisition of the Bile Acid Medicines from Travere, inventory acquired was valued at its fair value. As a result, our cost of sales exceeds the historical cost to manufacture the inventory and has a negative impact on our gross margin. We expect to sell the acquired inventory within the next two years from the balance sheet date. In addition, in connection with the acquisition, we have firm commitments for the purchase of minimum order quantities for active pharmaceutical ingredients. We periodically evaluate these firm commitments to determine if these commitments are in excess of our needs. If any net loss is determined, we record a charge to cost of sales in the period identified.

Prior to the regulatory approval of Livmarli, the manufacturing and related costs were expensed as research and development as any future economic benefit was not considered probable; accordingly, these costs were not capitalized and as a result gross margins resulting from product sales were initially higher until inventories that we had expensed prior to receiving approval were depleted. As of December 31, 2023, such inventories were substantially depleted.

Operating Expenses

Research and Development Expenses

Research and development expenses primarily relate to clinical development and manufacturing activities of our product candidates. Our research and development expenses include, among other things:

•
salaries and related expenses for employee personnel, including benefits, travel and expenses related to stock-based compensation granted to personnel in development functions;

•
external expenses paid to clinical trial sites, contract research organizations and consultants that conduct our clinical trials;

•
expenses related to drug formulation development and the production of clinical trial supplies, including fees paid to contract manufacturers;

97

•
licensing milestone payments related to development or regulatory events;

•
research and development funding for collaboration arrangements;

•
expenses related to non-clinical studies;

•
expenses related to compliance with drug development regulatory requirements; and

•
other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities, depreciation of equipment, and other supplies.

We expense research and development costs as incurred. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed. Upfront payments, research and development funding and milestone payments made to third parties in connection with licenses and research and development collaborations are expensed as incurred.

Our research and development expense may increase in the future as we continue to develop our current product candidates and look to acquire and develop additional product candidates.

Selling, General and Administrative Expense

Sales and marketing expense, which is a component of selling, general and administrative expense, primarily consisted of employee-related expenses for our sales group, brand marketing, patient support groups and pre-commercialization expenses related to our product candidates. General and administrative expense, which is a component of selling, general and administrative expense, primarily consists of corporate support and other administrative expenses, including employee-related expenses.

We anticipate that our selling, general and administrative expenses will increase in the future to support our continued commercialization efforts of our approved medicines in the United States and internationally as well as increased costs of operating as a global commercial stage biopharmaceutical public company. These increases will likely include increased costs related to hiring of additional personnel and fees to outside consultants to support further marketing, legal, tax, planning and accounting activities.

Loss from termination of revenue interest purchase agreement

Loss from termination of RIPA is related to the repurchase and termination of the RIPA in the second quarter of 2023. The repurchase payment included a premium over the remaining revenue interest liability and resulted in the recognition of a loss from termination of RIPA in our consolidated statements of operations and comprehensive loss.

Interest Income

Interest income consists of interest earned on our cash equivalents and investments.

Interest Expense

We incur interest expense on our convertible notes and on the RIPA. Interest on our convertible notes consists of a 4% per annum fixed rate of interest and amortization of debt discount and amortization costs. Interest on the RIPA consisted primarily of costs associated with our liability and non-cash interest costs associated with the amortization of the related debt discount and deferred issuance costs. Prior to extinguishment of the RIPA in the second quarter of 2023, we imputed interest expense associated with this liability using the effective interest rate method which is calculated based on the rate that would enable the debt to be repaid in full over the anticipated life of the arrangement.

Other Expense, Net

Other expense, net consists of gain or loss from remeasurement of the liabilities associated with the common stock issued in connection with the acquisition of Satiogen after the satisfaction of certain purchase price adjustments and indemnification obligations that may arise during the 12 month period following the asset

98

acquisition date (“Indemnification Holdback”) and the liability associated with the common stock to be issued in connection with the acquisition of Satiogen as contingent consideration upon achievement of a certain milestone (“Contingent Milestone”) both of which were recorded in connection with our acquisition of Satiogen, unrealized and realized currency gains and losses on net assets and liabilities denominated in foreign currency.

Critical Accounting Estimates

The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles (“GAAP”) and our discussion and analysis of our financial condition and operating results require our management to make judgments, assumptions and estimates that affect the amounts reported, including the amount of assets, liabilities, expenses and the disclosure of contingent assets and liabilities. Note 2, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report describes the significant accounting policies and methods used in the preparation of our consolidated financial statements. Management bases its estimates on historical experience, known trends and events, and on various other assumptions it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ materially from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in the notes to our consolidated financial statements appearing elsewhere in this Annual Report, we believe the following accounting policies are the most critical for fully understanding and evaluating our financial condition and results of operations.

Intangible Assets, Net

Intangible assets, net are measured at their fair values as of the acquisition date or, in the case of commercial milestone payments, the date they become due. Intangible assets are generally amortized on a straight-line basis over their estimated useful lives. We base the useful lives and related amortization expense on the period of time we estimate the assets will generate net product sales or otherwise be used. We also periodically review the lives assigned to our intangible assets to ensure that our initial estimates do not exceed any revised estimated periods from which we expect to realize cash flows from the technologies. If a change were to occur in any of the above-mentioned factors or estimates, the likelihood of a material change in our reported results would increase.

We evaluate our intangible assets with finite lives for indications of impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that could trigger an impairment review include significant under-performance relative to expected historical or projected future operating results, significant changes in the manner of our use of the acquired assets or the strategy for our overall business or significant negative industry or economic trends. If this evaluation indicates that the value of the intangible asset may be impaired, we make an assessment of the recoverability of the net carrying value of the asset over its remaining useful life. If this assessment indicates that the intangible asset is not recoverable, based on the estimated undiscounted future cash flows of the technology over the remaining amortization period, we reduce the net carrying value of the related intangible asset to fair value and may adjust the remaining amortization period.

We make significant judgments in relation to the valuation of intangible assets resulting from asset acquisitions, particularly in the forecasts of future operating results that are used in the discounted cash flow valuation models. It is possible that plans may change and estimates used may prove to be inaccurate. If our actual results, or the plans and estimates used in future impairment analyses, are lower than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges.

Product Sales, Net

Revenues from direct product sales are recorded net of reserves established for applicable discounts and allowances that are offered within contracts with our customers, including amounts from payors and other third parties on behalf of our customers. For revenues from partner markets, we record net product sales based on the estimated variable consideration to be received when the product is sold. The transaction price, which may include fixed or variable consideration reflecting the impact of discounts and allowances, may be subject to constraint and is included in the product sales price only to the extent that it is probable that a significant reversal of the amount of the cumulative revenue recognized will not occur in a future period. We recognize our best estimate of the

99

consideration that we expect to receive when control of the inventory is transferred to our customer and revenue is recognized. Estimates are reviewed and updated quarterly as additional information becomes known. Actual amounts may ultimately differ from our estimates. If actual results vary, we adjust these estimates, which could have an effect on earnings in the period of adjustment.

Government Rebates

We are obligated to pay rebates for mandated discounts under the Medicaid Drug Rebate Program. Our 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. We update estimates and assumptions on a quarterly basis and record any necessary adjustments to revenue in the period identified. Estimated rebates are recorded as a reduction of revenue in the period the related sale is recognized. To date, actual government rebates have not differed materially from our estimates.

Revenue Interest Liability, Net

We imputed interest expense associated with this liability using the effective interest rate method. The effective interest rate was calculated based on the rate that would enable the debt to be repaid in full over the anticipated life of the arrangement. The effective interest rate on the liability varied during the term of the agreement depending on a number of factors, including the level of actual and forecasted product sales, net. We evaluated the interest rate quarterly based on actual product sales, net and on product sales, net forecasts utilizing the prospective method. In April 2023, we repurchased all future Revenue Interests and as a result, the RIPA was terminated in accordance with its terms.

At December 31, 2022, the revenue interest liability was calculated using our estimated global forecasted net sales of Livmarli at the time and was impacted by a debt discount comprising the estimated value of a bifurcated derivative liability and issuance costs incurred.

Cost of Product Sales

Prior to receiving approval from the FDA or other foreign regulatory authorities for a new medicine or new formulation, we expense all costs incurred related to the manufacture of such medicines as research and development expense because of the inherent risks associated with the development of a drug candidate, the uncertainty about the regulatory approval process and our lack of history for regulatory approval of drug candidates. Subsequent to receiving FDA or other foreign regulatory authority approval, when commercialization is considered probable and the future economic benefit is expected to be realized, we begin capitalizing inventory costs as incurred.

Cost of product sales consist of raw materials, manufacturing costs, transportation and freight, amortization of capitalized intangible assets, royalties and indirect overhead costs associated with the manufacturing and distribution of the Company’s approved products. Cost of product sales may also include period costs related to certain manufacturing services and inventory adjustment charges.

We analyze our inventory levels quarterly for obsolescence and, if required, adjust inventory to its net realizable value for quantities in excess of expected demand. The analysis uses quantitative forecast and historical demand considerations in combination with shelf life and stop sell dates in our estimates to evaluate inventory that may not be sellable. The resulting adjustments are recognized as Cost of Sales.

Accrued Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued expenses as of each balance sheet date. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. We accrue and expense clinical trial activities performed by third parties based upon estimates of the proportion of work completed over the life of the individual study and patient enrollment rates in accordance with agreements established with clinical research organizations, clinical trial sites and other vendors

100

associated with the clinical trials. We determine the estimates by reviewing contracts, vendor agreements and purchase orders and through discussions with internal clinical personnel and external service providers as to the progress or stage of completion of trials or services and the agreed-upon fee to be paid for such services.

We make estimates of accrued expenses as of each balance sheet date based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments, if necessary. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Nonrefundable advance payments for goods and services, including fees for process development or manufacturing and distribution of clinical supplies that will be used in future research and development activities, are deferred and recognized as expense in the period that the related goods are consumed or services are performed.

Although we do not expect our estimates to be materially different from amounts actually incurred, if our estimates of the status and timing of services performed differ from the actual status and timing of services performed, it could result in us reporting amounts that are too high or too low in any particular period. To date, there have been no material differences between our estimates of such expenses and the amounts actually incurred.

Uncertain Tax Positions

We are subject to income taxes in the United States and certain foreign jurisdictions. The evaluation of uncertain tax positions involves significant judgment in the interpretation and application of GAAP and complex tax laws. Although management believes our reserves are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in our reserves. Reserves are adjusted considering changing facts and circumstances, such as the closing of a tax examination or the refinement of an estimate. Resolution of these uncertainties in a manner inconsistent with management’s expectations could have a material impact on our financial condition and operating results.

Recent Accounting Pronouncements

A description of recent accounting pronouncements that may potentially impact our financial position, results of operations or cash flows is disclosed in Note 2 to our consolidated financial statements included elsewhere in this Annual Report.

101

Results of Operations for the Years Ended December 31, 2023 and 2022

In this section, we discuss the results of our operations for the year ended December 31, 2023, compared to the year ended December 31, 2022. For a discussion of the year ended December 31, 2022 compared to the year ended December 31, 2021, please refer to our Annual Report on Form 10-K filed with the SEC on March 8, 2023.

The following table summarizes our results of operations for the years ended December 31, 2023 and 2022 (in thousands):

Product Sales, Net

Product sales, net was $178.9 million for the year ended December 31, 2023, compared to $75.1 million for the year ended December 31, 2022. The increase in product sales, net was a result of our continued commercialization of Livmarli in the United States, in certain countries in Europe and other international sales through partner market supply orders and sales of Bile Acid Medicines for a partial year following the completion of the Bile Acid Portfolio Acquisition.

The following table disaggregates total Product sales, net:

License Revenue

License revenue was $7.5 million for the year ended December 31, 2023 due to the achievement of regulatory milestones by CANbridge and GC Biopharma associated with our license agreements, compared to $2.0 million for the year ended December 31, 2022, due to the achievement of a regulatory milestone by CANbridge associated with our license agreement.

102

Cost of Sales

Cost of sales was $47.0 million for the year ended December 31, 2023, compared to $12.4 million for the year ended December 31, 2022. The increase in cost of sales was primarily a result of increased royalties payable of $9.8 million on net sales of Livmarli and the Bile Acid Medicines under licensing agreements, $7.5 million of amortization of acquired intangibles primarily associated with our acquisition of the Bile Acid Medicines in August 2023 and Satiogen in May 2022, a $5.2 million charge related to net losses associated with excess inventory from certain firm minimum purchase commitments in connection with our acquired Bile Acid Medicines, $3.9 million of increased costs associated with reserves for excess and obsolete inventory, increased product cost of sales of approximately $4.0 million primarily related to the Bile Acid Medicines and $4.0 million of increased commercial product development and supply chain costs.

Research and Development Expenses

The following table summarizes the period-over-period changes in research and development expenses relating to our product candidates in development for the periods indicated (in thousands):

Research and development expenses were $102.6 million for the year ended December 31, 2023, a decrease of $4.2 million compared to the year ended December 31, 2022. The decrease was primarily due to:

•
for Livmarli programs, a decrease of $10.8 million, primarily due to decreases of $5.4 million in manufacturing development expenses, $3.1 million in clinical trial expenses primarily related to the MARCH Phase 3 clinical trial which was completed during 2022 and $2.4 million in non-clinical and general research and development expenses; and

•
for volixibat programs, a decrease of $0.9 million, primarily due to a $3.3 million decrease in clinical expenses associated with the discontinuation of the intrahepatic cholestasis of pregnancy clinical trial and lower clinical manufacturing expenses of $1.8 million, partially offset by an increase of $4.1 million of clinical trial expenses for PSC and PBC.

The decreases were partially offset by increases due to:

•
for personnel related expenses, an increase of $3.3 million, related to an increase in employee headcount to support our development pipeline; and

•
for other expense, an increase of $3.3 million, primarily due to other general research and development activities.

Selling, General and Administrative Expenses

Selling, general and administrative expenses were $145.9 million for the year ended December 31, 2023, an increase of $56.8 million compared to the year ended December 31, 2022. The increase was primarily due to an increase of $26.6 million in personnel and other compensation related expenses, including an increase of $7.2 million in stock-based compensation, reflecting an increase in the number of our selling, marketing and administrative employees to support commercial activities for our approved medicines, and costs associated with the acquisition of the Bile Acid Portfolio and international expansion. The increase was also due to $17.0 million in expenses primarily related to legal, public relations, accounting and international expansion activities, $9.6 million

103

in advertising, promotion and medical affairs associated with commercial activities of our approved medicines and $3.5 million in other general administrative expenses.

Loss from termination of revenue interest purchase agreement

Loss from termination of RIPA was $49.1 million for the year ended December 31, 2023, compared to zero for the year ended December 31, 2022. The loss was related to the premium paid to repurchase the revenue interests pursuant to the RIPA.

Interest Income

Interest income was $13.7 million for the year ended December 31, 2023, an increase of $9.9 million compared to the year ended December 31, 2022. The increase was primarily due to higher interest earned on our cash equivalents and investment balances largely due to higher money market and treasury yields and higher cash equivalent balance throughout the year ended December 31, 2023.

Interest Expense

Interest expense was $15.1 million for the year ended December 31, 2023, a decrease of $0.9 million compared to the year ended December 31, 2022. For the year ended December 31, 2023, interest expense consisted of $10.0 million related to our convertible notes and $5.1 million related to the RIPA prior to extinguishment. For the year ended December 31, 2022, interest expense of $16.0 million was related to the RIPA.

Change in Fair Value of Derivative Liability

Change in fair value of derivative liability for the year ended December 31, 2022 was a gain of $0.9 million and was related to the remeasurement of the derivative liability at December 31, 2022. The gain reflects a decrease in value of the put option associated with the RIPA attributable to the decay in time value of the put option. There was no change in the estimated fair value of the derivative liability in 2023 prior to extinguishment of the RIPA.

Other (Expense) Income, Net

Other (expense) income, net was an expense of $2.8 million, net for the year ended December 31, 2023, compared to an income of $0.4 million, net for the year ended December 31, 2022. For the year ended December 31, 2023, the expense was primarily attributable to $1.8 million in unrealized currency losses on net assets and liabilities denominated in foreign currency, $0.7 million of expense associated with the remeasurement of the Contingent Milestone liability and the Indemnification Holdback liability prior to issuance of the underlying common stock as well as $0.4 million of realized currency loss. For the year ended December 31, 2022, the income was primarily related to the remeasurement of the Contingent Milestone liability and the Indemnification Holdback liability of $0.9 million and $0.3 million of unrealized currency gains on net assets and liabilities denominated in foreign currency, partially offset by $0.8 million of realized currency losses.

Provision For (Benefit From) Income Taxes

Provision for income taxes was $1.0 million for the year ended December 31, 2023 compared to a benefit from income taxes of $6.4 million for the year ended December 31, 2022. The change was related to the deferred tax liability recognized as a result of intangible assets acquired as part of the Satiogen acquisition and corresponding reduction in our valuation allowance against our net deferred tax assets during the year ended December 31, 2022.

Liquidity and Capital Resources

Overview

Since inception, we have funded our operations primarily through debt, equity, a revenue interest financing and, to a lesser extent, cash from our product sales and license and collaboration revenue. We had $286.3 million of cash and cash equivalents as of December 31, 2023, compared to cash, cash equivalents, restricted cash equivalents and investments of $251.7 million as of December 31, 2022. Since inception, we have incurred operating losses and

104

negative cash flows from operations. As of December 31, 2023, we had an accumulated deficit of $556.2 million, compared to $392.8 million as of December 31, 2022.

On August 31, 2023, we completed the Bile Acid Portfolio Acquisition for an aggregate purchase price of up to $445.0 million in cash, with $210.4 million paid at the Closing and up to $235.0 million upon achievement of certain milestones based on specified amounts of annual net sales (tiered from $125.0 million to $500.0 million) of the Bile Acid Medicines. In connection with and immediately prior to the closing of the Bile Acid Portfolio Acquisition, we completed the private placement of 8,000,000 shares of our common stock at a price per share of $26.25, resulting in net proceeds of approximately $202.2 million which we used to finance the upfront payment at the closing of the Bile Acid Portfolio Acquisition.

On April 17, 2023, we completed an offering of $316.3 million aggregate principal of the Notes, which includes the exercise of the initial purchasers’ option in full. The offering resulted in net proceeds of $305.3 million after deducting the initial purchasers’ discounts and commissions and offering expenses. The terms of the convertible Notes are further described in Note 10 to our consolidated financial statements. We used a portion of the net proceeds to repurchase the revenue interests from the Purchasers at a call price of $192.7 million. Upon repurchase of the revenue interests from the Purchasers, the RIPA, in accordance with its terms, was terminated with no further payments due to the Purchasers and the $100.0 million of our previously restricted cash equivalents was no longer restricted from use.

In September 2022, we filed an automatic statement on Form S-3 with the SEC (the “2022 Shelf Registration”), which became effective upon filing, pursuant to which we registered for sale from time to time in one or more offerings an unlimited amount of any combination of our common stock, preferred stock, debt securities and warrants, so long as we continue 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 December 31, 2023, we have not issued any securities pursuant to the 2022 Shelf Registration. We may lose well-known seasoned issuer status in the future upon the occurrence of certain events prescribed by the Securities Act or the rules and regulations of the SEC occurring after we file this Quarterly Report if, at the time of those certain events, the worldwide market value of our voting and non-voting common equity held by our non-affiliates does not equal $700.0 million or more, calculated as of a date within 60 days prior to such events. If that were to occur and we were no longer considered a well-known seasoned issuer, we anticipate needing to amend our automatic shelf registration statement on Form S-3 prior to the occurrence of such events in order to sell securities under that Form S-3 on an ongoing basis.

On November 2, 2023, we entered into a Sales Agreement (the “2023 Sales Agreement”) with Leerink and Cantor Fitzgerald & Co. (the “Sales Agents”), pursuant to which we may, from time to time, sell up to an aggregate amount of $200.0 million of our common stock through the Sales Agents in an “at-the-market” offering (the “ATM Offering”) pursuant to the 2022 Shelf Registration. We are not required to sell shares under the 2023 Sales Agreement. Sales of our 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. We 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 it pursuant to the 2023 Sales Agreement. No sales may be made under the 2023 Sales Agreement until a prospectus supplement relating to the ATM Offering is filed with the Securities and Exchange Commission.

In August 2020, the SEC declared effective the 2020 Shelf Registration covering the sale of up to $300.0 million of our securities. Also, in August 2020, we entered into the 2020 Sales Agreement with Leerink pursuant to which we could issue and sell, in an at the market offering, from time to time, shares of common stock having an aggregate offering price of up to $75.0 million under the 2020 Shelf Registration through Leerink acting as the sales agent and/or principal. During the year ended December 31, 2023 we issued and sold 658,206 shares of common stock pursuant to the 2020 Sales Agreement resulting in aggregate gross proceeds to us of $15.0 million. For the year ended December 31, 2023, the net proceeds to us after deducting sales commissions to Leerink and other issuance expenses were approximately $14.5 million. As of December 31, 2023, we have 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 us of $43.7 million. The 2020 Shelf Registration expired in August 2023, and no further sales may be made under the 2020 Sales Agreement.

In August 2022, we completed an underwritten public offering of our common stock pursuant to the 2020 Shelf Registration. We sold 3,478,261 shares of common stock at a price to the public of $23.00 per share. In addition, we granted the underwriters an option, exercisable for 30 days, to purchase up to 521,739 additional shares of our common stock at the public offering price, less the underwriting discounts, commissions and offering expenses, which the underwriters exercised in full. The underwritten public offering, including the underwriters’ exercise of their option, resulted in net proceeds to us of $86.1 million after deducting underwriting discounts, commissions and offering expenses.

Based on our current and anticipated level of operations and cash generated from sales of our approved medicines, we believe our existing cash and cash equivalents will be sufficient to fund our planned operations through at least the next 12 months from the filing of this Annual Report and beyond. Our cash and cash equivalents include readily available checking and money market funds. We maintain established guidelines relating to diversification and maturities of our investments to preserve principal and maintain liquidity.

We anticipate that we will continue to incur net losses for the foreseeable future as we continue research efforts and the development of our product candidates, continue commercialization activities for our approved medicines and potentially expand into additional markets, hire additional staff, including clinical, scientific, operational, financial and management personnel and pay potential development and commercial and sales based milestones.

Our primary use of cash is to fund operating expenses. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.

Although Livmarli has been approved for the treatment of cholestatic pruritus in patients with ALGS in patients three months of age and older and cholestatic pruritus in patients with PFIC five years of age and older in the U.S. and for the treatment of cholestatic pruritus in ALGS patients two months of age and older in Europe, and we expect product revenues to increase as we continue commercial activities, Livmarli may not achieve commercial success. Certain of our approved medicines, including the Bile Acid Medicines, are subject to immediate competition from compounded and generic entrants, as the ANDA and NDA for these drug products have no remaining or current patent or non-patent exclusivity. In addition, Chenodal is approved for radiolucent stones in the gallbladder yet is used primarily as standard of care for CTX. The FDA has provided a letter acknowledging Chenodal as a medical necessity for CTX, but prescriptions for this indication are not on label. As such, any change in this view from the FDA could adversely affect our ability to sell Chenodal in this indication. Unless and until Chenodal is approved for CTX, we cannot market or promote Chenodal for CTX which limits its growth potential.

Our principal source of liquidity is product revenue from sales of approved medicines, and, to a lesser extent, from our collaboration agreements. Until such time, if ever, as we can generate sufficient product revenue from sales of our approved medicines, our current product candidates or any future product candidates, if approved, to fund operations, we expect to finance our cash needs through a combination of equity offerings, debt financings and potential collaboration, license or development agreements. Our primary cash needs are for day-to-day operations and to fund our working capital requirements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect rights as a stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. As a result of adverse geopolitical and macroeconomic developments, such as the ongoing military conflicts between Ukraine and Russia and in Israel and the surrounding areas, and related sanctions, actual and anticipated changes in interest rates, economic inflation and the responses by central banking authorities to control such inflation, bank failures, the global credit and financial markets have experienced volatility and disruptions, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. If the equity and credit markets

106

deteriorate, it may make any necessary debt or equity financing more difficult, more costly and more dilutive. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our drug development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Contractual Obligations

In addition to ongoing capital needs to fund our ongoing operations, our material cash requirements include the following contractual and other obligations.

On April 17, 2023, we completed an offering of $316.3 million aggregate principal of the Notes, which includes the exercise of the initial purchasers’ option in full. The offering resulted in net proceeds of $305.3 million after deducting the initial purchasers’ discounts and commissions and offering expenses. The Notes are our senior, unsecured obligations and accrue interest at a rate of 4.00% per annum, payable semi-annually in arrears on May 1 and November 1 of each year. Our first interest payment was due on November 1, 2023. The Notes will mature on May 1, 2029, unless earlier converted, redeemed or repurchased by us. The terms of these Notes are further described in Note 10 to our consolidated financial statements.

We used a portion of the net proceeds from the Notes to repurchase the revenue interests from the Purchasers at a call price of $192.7 million. Upon repurchase of the revenue interests from the Purchasers, the RIPA, in accordance with its terms, was terminated with no further payments due to the Purchasers.

Under the Shire License Agreement and Asset Purchase Agreement with Travere, as well as our other license and acquisition agreements, we have payment obligations that are contingent upon future events such as our achievement of specified development, regulatory and commercial milestones and are required to make royalty payments in connection with the sale of products developed under those agreements. The amount and timing of milestone obligations are unknown or uncertain as we are unable to estimate the timing or likelihood of achieving the milestone events. Additionally, the amount of royalty payments are based upon future product sales, which we are unable to predict with certainty. These potential obligations are further described in Note 7 to our consolidated financial statements.

We additionally have contractual obligations for our operating leases for our corporate headquarters. These obligations are further described in Note 9 to our consolidated financial statements.

We are party to certain license and collaboration agreements, which contain a number of contractual obligations. Those contractual obligations may entitle us to receive, or may obligate us to make, certain payments. The amount and timing of those payments are unknown or uncertain as we are unable to estimate the timing or likelihood of the events that will obligate those payments.

We enter into contracts in the normal course of business with clinical research organizations and clinical sites for the conduct of clinical trials, non-clinical research studies, professional consultants for expert advice and other vendors for clinical supply manufacturing or other services. These contracts generally provide for termination on notice, and therefore are cancelable contracts.

We enter into commercial inventory supply agreements that obligate us to firm commitments for the purchase of minimum order quantities, which may be material to our financial statements.
