Computed values are grepcent-computed from the verified facts above and may differ from ratios the company itself reports. Free cash flow = operating cash flow − capital expenditures. Net margin = net income ÷ revenue. Operating margin = operating income ÷ revenue. Revenue YoY = FY2025 revenue ÷ FY2024 revenue − 1 (consecutive fiscal years only). ROE = net income ÷ period-end stockholders' equity.

Item 2. 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 in conjunction with our unaudited condensed consolidated financial statements and the related notes and other financial information included elsewhere in this Quarterly Report on Form 10-Q and our audited consolidated financial statements and notes thereto and the related Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K (“Annual Report”) for the year ended December 31, 2025, which was filed with the Securities and Exchange Commission (“SEC”) on February 25, 2026. Unless the context requires otherwise, references in this Quarterly Report on Form 10-Q to the “Company,” “Mirum,” “we,” “us” and “our” refer to Mirum Pharmaceuticals, Inc. and its consolidated subsidiaries.

Forward-Looking Statements

In addition to historical financial information, this discussion and analysis contains forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth in the section titled “Risk Factors” under Part II, Item 1A below. In some cases, you can identify forward-looking statements by terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potentially,” “predict,” “should,” “will” or the negative of these terms or other similar expressions.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

Overview

We are a biopharmaceutical company dedicated to transforming the treatment of rare diseases. We have three approved medicines: LIVMARLI® (maralixibat) (“Livmarli”), Cholbam® (cholic acid) capsules (“Cholbam”), and CTEXLI® (chenodiol) tablets (“Ctexli”).

Livmarli is a novel, orally administered, minimally-absorbed ileal bile acid transporter (“IBAT”) inhibitor (“IBATi”) that is approved for the treatment of cholestatic pruritus in patients with Alagille syndrome (“ALGS”) in the United States (“U.S.”), the European Union (“EU”) and various other countries around the world and for cholestatic pruritus in patients with progressive familial intrahepatic cholestasis (“PFIC”) in the U.S. and certain other countries and for the treatment of PFIC in the EU. We market and commercialize Livmarli in the U.S., Canada 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. In March 2025, our partner Takeda received approval from the Japanese Ministry of Health, Labour, and Welfare for Livmarli for the treatment of cholestatic pruritus in patients with ALGS and PFIC.

We market and commercialize Ctexli and Cholbam (also known as Kolbam) (and together with chenodiol, the “Bile Acid Medicines”) in the U.S. directly and indirectly in certain foreign markets. The U.S. Food and Drug Administration (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 peroxisome biogenesis disorder-Zellweger spectrum disorder (“PBD-ZSD”). Ctexli received FDA approval for the treatment of adults with cerebrotendinous xanthomatosis (“CTX”) in February 2025.

We are 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 primary sclerosing cholangitis (“PSC”) and primary biliary cholangitis (“PBC”), and in October 2024, we announced that the FDA granted Breakthrough Therapy designation for volixibat as a potential treatment for cholestatic pruritus in patients with PBC and recently completed enrollment and expect topline data in the first quarter of 2027. We announced topline results for the VISTAS Phase 2b clinical trial in PSC in May 2026. Based on these results, FDA granted Breakthrough Therapy designation for volixibat in cholestatic pruritus due to PSC. We completed a pre-NDA meeting with FDA in which the agency recommended a Phase 3 study of volixibat in PSC. We believe the VISTAS study and supporting data can support an NDA review and we plan to discuss a potential filing package with FDA as part of our planned breakthrough therapy Type B meeting. We now expect to submit a potential New Drug Application (“NDA”) to the FDA in the first half of 2027.

In addition, we are developing Livmarli for certain rare cholestatic conditions through the Phase 3 EXPAND study, which we initiated in the fourth quarter of 2024. We completed enrollment of the EXPAND study in the first half of 2026 with topline data expected in the fourth quarter of 2026.

In October 2024, we completed a license agreement with Enthorin Therapeutics, LLC and Dart Neuroscience LLC granting us the worldwide right to develop and commercialize MRM-3379, an allosteric inhibitor of Phosphodiesterase 4D (“PDE4D”). We are currently enrolling patients in the BLOOM Phase 2 clinical study of MRM-3379 in Fragile-X Syndrome (“FXS”) and expect topline data in 2027.

On January 23, 2026, we completed the acquisition (the “Bluejay Acquisition”) of Bluejay Therapeutics, Inc. (“Bluejay”) and its lead product candidate brelovitug (BJT-778). We are advancing brelovitug for the treatment of chronic hepatitis D virus (“HDV”) infection. Brelovitug is a fully human IgG1 monoclonal antibody that binds the hepatitis B surface antigen, thereby clearing virions and subviral particles and preventing HDV infection and replication. Brelovitug has been granted FDA Breakthrough Therapy designation, EMA Priority Medicines (“PRIME”) scheme designation and European Commission orphan medicinal product designation. Brelovitug is currently being evaluated in the global AZURE clinical program with topline results from the AZURE-1 and AZURE-4 registration-enabling clinical trials expected in the third and fourth quarter of 2026, respectively, and top-line results from the AZURE-2 and AZURE-3 registration-enabling clinical trials expected by the first half of 2028. We believe that the results from the AZURE-1 and AZURE-4 trials may support a potential biologics license application (“BLA”) submission to the FDA for brelovitug in HDV in the first half of 2027 followed by a potential approval and subsequent commercial launch, if approved, in the second half of 2027 in the U.S.

In April 2026, we entered into an agreement with Incyte Corporation (“Incyte”) whereby we obtained the right to develop and commercialize zilurgisertib. Zilurgisertib is an oral small molecule ALK2 inhibitor in development for the treatment of fibrodysplasia ossificans progressiva. The FDA has accepted for review Incyte’s NDA with a PDUFA date of September 26, 2026.

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 our approved medicines, and conducting business development activities relating to, among other things, portfolio expansion through collaborations and acquisitions.

Financial Overview

Our net loss was $67.2 million and $5.9 million for the three months ended June 30, 2026 and 2025, respectively, and $857.4 million and $20.5 million for the six months ended June 30, 2026 and 2025, respectively. As of June 30, 2026, we had an accumulated deficit of $1.5 billion, compared to $667.5 million as of December 31, 2025. As of June 30, 2026, we had unrestricted cash, cash equivalents and investments of $561.3 million, compared to unrestricted cash, cash equivalents and investments of $391.4 million as of December 31, 2025.

We anticipate we will continue to generate net 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 that total product sales of our approved medicines will continue to increase on an annual basis; however, due to large periodic orders from Takeda and our distributors, our product revenue may experience quarterly fluctuations. Additionally, our product revenues from Takeda are based upon variable consideration estimates. If actual results vary from our estimates, we will make adjustments in the period when such variances become known. 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, 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.

Components of Results of Operations

Revenue

Product Sales, Net

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

Our U.S. revenue from product sales, net further depends on our prescription mix of commercial payors and governmental programs. We expect our prescription mix and resulting gross to net adjustment in the U.S. to remain materially consistent. Our revenue from product sales is recognized when the control of the product is transferred. Under our license agreement with Takeda as well as agreements with distributors, we may receive large periodic orders for our products. The timing of these orders can be inconsistent and can create significant quarter-to-quarter variation in product sales. In addition, we recognize our best estimate of the consideration that we expect to receive when control of the inventory is transferred to our licensed partners and distributors. Such estimates may be complex and include estimates as to if and when our distributors and licensed partner’s sales in the market will occur. Estimates are reviewed and updated quarterly as additional information, includ

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 dedicated to transforming the treatment of rare diseases. We have three approved medicines: LIVMARLI® (maralixibat) (“Livmarli”), CHOLBAM® (cholic acid) capsules (“Cholbam”), and CTEXLI® (chenodiol) tablets (“Ctexli”).

Livmarli is a novel, orally administered, minimally-absorbed ileal bile acid transporter (“IBAT”) inhibitor (“IBATi”) that is approved for the treatment of cholestatic pruritus in patients with Alagille syndrome (“ALGS”) in the United States (“U.S.”), the European Union (“EU”) and various other countries around the world and for cholestatic pruritus in patients with progressive familial intrahepatic cholestasis (“PFIC”) in the U.S., Canada and Japan and for the treatment of PFIC in the EU. We market and commercialize Livmarli in the U.S., Canada 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. In March 2025, our partner Takeda received approval from the Japanese Ministry of Health, Labour, and Welfare for Livmarli for the treatment of cholestatic pruritus in patients with ALGS and PFIC.

In August 2023, we 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 chenodiol and Cholbam (also known as Kolbam) (and together with chenodiol, the “Bile Acid Medicines”) pursuant to an asset purchase agreement dated July 16, 2023 (such acquisition, the “Bile Acid Portfolio Acquisition”).

The U.S. Food and Drug Administration (“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 peroxisome biogenesis disorder-Zellweger spectrum disorder (“PBD-ZSD”). Chenodiol is standard of care for the treatment of cerebrotendinous xanthomatosis (“CTX”) in the U.S. with a medical necessity recognition by the FDA and was commercialized under the brand name Chenodal. We submitted a new drug application (“NDA”) for chenodiol for the treatment of CTX in 2024 and received FDA approval for the treatment of adults with CTX in February 2025, which is commercialized under the brand name Ctexli. We currently market and commercialize Cholbam and Ctexli in the U.S. through our specialized and focused commercial team. We have also assumed license and distribution agreements with several rare disease companies for the commercialization of Cholbam and chenodiol in additional countries.

We are 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 primary sclerosing cholangitis (“PSC”) and primary biliary cholangitis (“PBC”), and in October 2024, we announced that the FDA granted Breakthrough Therapy designation for volixibat as a potential treatment for cholestatic pruritus in patients with PBC. We conducted an interim analysis of our VISTAS Phase 2b clinical trial in PSC and reported interim data from our VANTAGE Phase 2b clinical trial in PBC in June 2024. The VISTAS Phase 2b clinical trial in PSC completed enrollment in the third quarter of 2025 and topline data is expected in the second quarter of 2026. In addition, we expect to submit an NDA to the FDA for volixibat for the treatment of PSC in the second half of 2026, with both potential approval and subsequent launch of volixibat for the treatment of PSC, if approved, to occur in the first half of 2027. We expect the VANTAGE Phase 2b clinical trial in PBC to complete enrollment in the second half of 2026 with topline data expected in the first half of 2027.

In addition, we are developing Livmarli for certain rare cholestatic conditions through the Phase 3 EXPAND study, which we initiated in the fourth quarter of 2024. We expect to complete enrollment of the EXPAND study in the first half of 2026 with topline data expected in the fourth quarter of 2026.

We are currently enrolling patients in the BLOOM Phase 2 clinical study of MRM-3379 in Fragile-X Syndrome (“FXS”) and expect topline data in 2027.

On January 23, 2026, we completed the acquisition (the “Bluejay Acquisition”) of Bluejay Therapeutics, Inc. (“Bluejay”) and its lead product candidate brelovitug (BJT-778). We are advancing brelovitug for the treatment of chronic hepatitis D virus (“HDV”) infection. Brelovitug is a fully human IgG1 monoclonal antibody that binds the hepatitis B surface antigen, thereby clearing virions and subviral particles and preventing HDV infection and replication. Brelovitug has been granted FDA Breakthrough Therapy designation, EMA Priority Medicines (“PRIME”) scheme designation and European Commission orphan medicinal product designation. Brelovitug is currently being evaluated in the global AZURE clinical program with topline results from the AZURE-1 and AZURE-4 registration-enabling clinical trials expected in the second half of 2026 and top-line results from the AZURE-2 and AZURE-3 registration-enabling clinical trials expected by the first half of 2028. We believe that the results from the AZURE-1 and AZURE-4 trials may support a potential biologics license application submission to the FDA for brelovitug in HDV in the first half of 2027 followed by a potential approval and subsequent launch, if approved, in the second half of 2027. We believe that the results of the AZURE-2 and AZURE-3 clinical trials may support a potential EMA registration and subsequent commercial launch, if approved, in the EU.

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 our approved medicines, and conducting business development activities relating to, among other things, portfolio expansion through collaborations and acquisitions.

Financial Overview

Our net loss was $23.4 million and $87.9 million for the years ended December 31, 2025 and 2024, respectively. As of December 31, 2025, we had an accumulated deficit of $667.5 million compared to $644.2 million as of December 31, 2024. As of December 31, 2025, we had unrestricted cash, cash equivalents and investments of $391.4 million, compared to $292.8 million as of December 31, 2024.

While we generated net income in the third quarter of 2025, we anticipate we will continue to generate net losses for the foreseeable future as we continue commercial activities for our approved medicines, conduct our ongoing and planned clinical trials, including the clinical trials for brelovitug, 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 that total product sales of our approved medicines will continue to increase on an annual basis; however, due to large periodic orders from Takeda and our distributors, our product revenue may experience quarterly fluctuations. Additionally, our product revenues from Takeda are based upon variable consideration estimates. If actual results vary from our estimates, we will make adjustments in the period when such variances become known. 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, 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.

License agreement with Enthorin

In October 2024, we completed the in-license of MRM-3379. We paid a one-time non-refundable license fee of $7.5 million upon closing of the transaction, and up to an additional $217.5 million is payable upon achievement of certain development, regulatory and commercial milestones.

Asset Purchase Agreement with Travere Therapeutics, Inc.

In August 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. As of December 31, 2025, the Company accrued $25.0 million for the achievement of a commercial milestone associated with achievement of certain net product sales, which was recognized as an intangible asset in the accompanying consolidated balance sheet as of December 31, 2025 and is expected to be paid in the first quarter of 2026.

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.

Acquisition of Bluejay Therapeutics

On January 23, 2026, we completed the Bluejay Acquisition and acquired Bluejay’s lead product candidate brelovitug (BJT-778). Upon the closing of the merger, we paid to the holders of Bluejay’s securities an aggregate amount of $224.2 million in cash, net of cash acquired in the transaction, and 4,673,597 shares of our common stock, subject in certain cases to deduction to satisfy applicable taxes. We will also pay up to an aggregate amount of $25.8 million in cash and up to 522,375 shares of our common stock, subject to deduction for taxes and certain holdbacks pursuant to the terms and conditions of the definitive acquisition agreement. Additionally, we are obligated to pay up to an aggregate of $200.0 million upon achievement of certain commercial m
