Insights

Travere posts strong FILSPARI-driven growth and turns non-GAAP profitable.

Travere Therapeutics delivered Q1 2026 revenue of $127.2 million, up from $81.7 million a year earlier, mainly from FILSPARI. U.S. FILSPARI sales were $105.2 million, an 88% year-over-year increase, reflecting growing adoption in IgA nephropathy.

GAAP net loss narrowed to $37.1 million, but on a non-GAAP basis the company generated $4.1 million in net income, indicating that underlying operations are approaching break-even despite higher R&D and SG&A tied to launches. Cash, cash equivalents and marketable securities totaled $264.7 million as of March 31, 2026.

FDA approval of FILSPARI in focal segmental glomerulosclerosis expands the addressable U.S. population for FILSPARI to more than 100,000 patients across IgAN and FSGS. The restarted Phase 3 HARMONY Study of pegtibatinase in classical homocystinuria, with topline data expected in 2H 2027, adds a longer-term pipeline catalyst.

"On a non-GAAP adjusted basis, net income for the first quarter of 2026 was $4.1 million"
Non-GAAP net income is a company's profit figure that excludes certain costs or income that are included in standard accounting methods. Companies often use it to show what their earnings might look like without one-time expenses or other unusual items, helping investors see the company's core performance more clearly.

"FDA approved FILSPARI to reduce proteinuria in adult and pediatric patients aged 8 years and older with FSGS without nephrotic syndrome"
A disease in which parts of the kidney’s tiny filters become scarred and stop working properly, causing protein to leak into the urine and progressively reducing kidney function. Think of it as a coffee filter developing holes and clogs: the filter can’t keep the liquid clean, which can lead to costly treatment or dialysis if it worsens. Investors watch it because the condition drives demand for diagnostics, drugs, and procedures, influences clinical trial activity and regulatory outcomes, and can affect healthcare spending and company revenues in the nephrology and biotech sectors.

Travere Therapeutics Reports First Quarter 2026 Financial Results
FILSPARI achieved record 993 new PSFs for IgAN in the U.S. in the first quarter; U.S. net product sales grew 88% year-over-year to $105 million
FDA approval in FSGS expands total addressable FILSPARI patient population in the U.S. to more than 100,000; first FSGS patients treated within one week of approval
First new patient dosed in restarted Phase 3 HARMONY Study of pegtibatinase; Topline data expected 2H 2027

SAN DIEGO, May 4, 2026 – Travere Therapeutics, Inc. (Nasdaq: TVTX) today reported its first quarter 2026 financial results and provided a corporate update.
“This has been a transformative start to the year for Travere, highlighted by the landmark approval of FILSPARI in FSGS, record demand that reinforces FILSPARI’s foundational position in IgAN, and the advancement of pegtibatinase with the first new patient dosed in the restarted Phase 3 HARMONY study,” said Eric Dube, Ph.D., president and chief executive officer of Travere Therapeutics. “With FILSPARI now positioned to help more than 100,000 patients across IgAN and FSGS, we see a substantial and durable growth opportunity ahead, supporting a compelling long-term trajectory for the Company.”
Financial Results for the Quarter Ended March 31, 2026
U.S. net product sales for the first quarter of 2026 were $124.5 million, compared to $75.9 million for the same period in 2025. The increase is attributable to growth in sales of FILSPARI.
Research and development (R&D) expenses for the first quarter of 2026 were $57.1 million, compared to $46.9 million for the same period in 2025. The increase is primarily attributable to the restart of the Phase 3 HARMONY Study of pegtibatinase in classical HCU. On a non-GAAP adjusted basis, R&D expenses were $51.5 million for the first quarter of 2026, compared to $42.2 million for the same period in 2025.
Selling, general, and administrative (SG&A) expenses for the first quarter of 2026 were $80.3 million, compared to $60.4 million for the same period in 2025. The difference is largely attributable to investments in preparing for FILSPARI’s launch in FSGS as well as commercial investments in IgAN. On a non-GAAP adjusted basis, SG&A expenses were $69.3 million for the first quarter of 2026, compared to $53.3 million for the same period in 2025.
Total other income, net for the first quarter of 2026 was $0.2 million, compared to $1.5 million for the same period in 2025.
Net loss for the first quarter of 2026 was $37.1 million, or $0.40 per basic share, compared to a net loss of $41.2 million, or $0.47 per basic share for the same period in 2025. On a non-GAAP adjusted basis, net income for the first quarter of 2026 was $4.1 million, or $0.05 per basic share, compared to a net loss of $16.9 million, or $0.19 per basic share for the same period in 2025.
As of March 31, 2026, the Company had cash, cash equivalents, and marketable securities of $264.7 million. This amount does not include the $25 million sales-based milestone from Mirum Pharmaceuticals, which was recognized in 2025 and received in April 2026.

FILSPARI® (sparsentan) – Focal Segmental Glomerulosclerosis (FSGS)
•On April 13, 2026, the U.S. Food and Drug Administration (FDA) approved FILSPARI to reduce proteinuria in adult and pediatric patients aged 8 years and older with FSGS without nephrotic syndrome.
•Patients with FSGS without nephrotic syndrome span across types of FSGS and represent a population aligned with the KDIGO guidelines for treating glomerular diseases. Nephrotic syndrome is commonly defined as the presence of three concurrent criteria: proteinuria greater than 3.5 g/24h, edema, and albumin less than 3.0 g/dL.
•FILSPARI is the first and only FDA-approved medicine for FSGS, with an estimated addressable population in the U.S. of more than 30,000 patients without nephrotic syndrome.
•The Company received its first FSGS patient start forms on the first day following approval, with reimbursed FILSPARI treatments initiated within the first week of approval.
•At the NKF Spring Clinical Meeting (May 7–10), the Company will present additional Phase 3 DUPLEX data, including results from patients who switched from irbesartan to FILSPARI in the open-label extension.
Pegtibatinase (TVT-058) – Classical Homocystinuria (HCU)
•In the first quarter of 2026, the Company restarted enrollment activities in the pivotal Phase 3 HARMONY Study of pegtibatinase for the treatment of HCU. The study is expected to enroll approximately 70 patients aged 12 to 65 with plasma total homocysteine (tHcy) levels ≥50 µM. The primary endpoint is change from baseline in plasma tHcy levels, averaged across weeks 6 through 12, in patients receiving pegtibatinase compared with those receiving placebo, with durability of response through Week 24 as a key secondary endpoint.
•In April 2026, the Company dosed the first new patient following the study restart, with topline data anticipated in 2H 2027.
•Pegtibatinase has the potential to become the first and only disease-modifying therapy for people living with HCU.

Use of Non-GAAP Financial Measures
To supplement Travere’s financial results and guidance presented in accordance with U.S. generally accepted accounting principles (GAAP), the Company uses certain non-GAAP adjusted financial measures in this press release and the accompanying tables. The Company believes that these non-GAAP financial measures are helpful in understanding its past financial performance and potential future results. They are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read in conjunction with the consolidated financial statements prepared in accordance with GAAP. Travere’s management regularly uses these supplemental non-GAAP financial measures internally to understand, manage and evaluate its business and make operating decisions. In addition, Travere believes that the use of these non-GAAP measures enhances the ability of investors to compare its results from period to period and allows for greater transparency with respect to key financial metrics the Company uses in making operating decisions.
Investors should note that these non-GAAP financial measures are not prepared under any comprehensive set of accounting rules or principles and do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP. Investors should also note that these non-GAAP financial measures have no standardized meaning prescribed by GAAP and, therefore, have limits in their usefulness to investors. In addition, from time to time in the future the Company may exclude other items, or cease to exclude items that it has historically excluded, for purposes of its non-GAAP financial measures; because of the non-standardized definitions, the non-GAAP financial measures as used by the Company in this press release and the accompanying tables may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by the Company’s competitors and other companies.
As used in this press release, (i) the historical non-GAAP net income (loss) measures exclude from GAAP net income (loss), as applicable, stock-based compensation expense, amortization and depreciation expense, and income tax; (ii) the historical non-GAAP SG&A expense measures exclude from GAAP SG&A expenses, as applicable, stock-based compensation expense, and amortization and depreciation expense; (iii) the historical non-GAAP R&D expense measures exclude from GAAP R&D expenses, as applicable, stock-based compensation expense, and amortization and depreciation expense; (iv) royalty expense excludes amortization expense.

FILSPARI® (sparsentan) U.S. Indication
FILSPARI® (sparsentan) is indicated:
•To slow kidney function decline in adults with primary immunoglobulin A nephropathy (IgAN) who are at risk for disease progression.
•To reduce proteinuria in adult and pediatric patients aged 8 years and older with focal segmental glomerulosclerosis (FSGS) without nephrotic syndrome.
IMPORTANT SAFETY INFORMATION
BOXED WARNING: HEPATOTOXICITY AND EMBRYO-FETAL TOXICITY
Because of the risk of hepatotoxicity, FILSPARI is available only through a restricted program called the FILSPARI REMS. Under the FILSPARI REMS, prescribers, patients and pharmacies must enroll in the program.
Hepatotoxicity
Some Endothelin Receptor Antagonists (ERAs) have caused elevations of aminotransferases, hepatotoxicity, and liver failure. In clinical studies, elevations in aminotransferases (ALT or AST) of at least 3-times the Upper Limit of Normal (ULN) have been observed in up to 3.5% of FILSPARI-treated patients, including cases confirmed with rechallenge.
Measure transaminases and bilirubin before initiating treatment and then every 3 months during treatment. Interrupt treatment and closely monitor patients who develop aminotransferase elevations more than 3x ULN.
FILSPARI should generally be avoided in patients with elevated aminotransferases (>3x ULN) at baseline because monitoring for hepatotoxicity may be more difficult and these patients may be at increased risk for serious hepatotoxicity.
Embryo-Fetal Toxicity
FILSPARI is contraindicated for use during pregnancy because it may cause fetal harm if used by pregnant patients. Therefore, in patients who can become pregnant, exclude pregnancy prior to initiation of FILSPARI. Advise use of effective contraception before the initiation of treatment, during treatment, and for two weeks after discontinuation of treatment with FILSPARI. When pregnancy is detected, discontinue FILSPARI as soon as possible.
Contraindications
FILSPARI is contraindicated in patients who are pregnant. Do not coadminister FILSPARI with angiotensin receptor blockers (ARBs), ERAs, or aliskiren.
Warnings and Precautions
•Hepatotoxicity: Elevations in ALT or AST of at least 3-fold ULN have been observed in up to 3.5% of FILSPARI-treated patients, including cases confirmed with rechallenge. While no concurrent elevations in bilirubin >2-times ULN or cases of liver failure were observed in FILSPARI-treated patients in clinical trials, some ERAs have caused elevations of aminotransferases, hepatotoxicity, and liver failure. To reduce the risk of potential serious hepatotoxicity, measure serum aminotransferase levels and total bilirubin prior to initiation of treatment and then every 3 months during treatment.
Advise patients with symptoms suggesting hepatotoxicity (nausea, vomiting, right upper quadrant pain, fatigue, anorexia, jaundice, dark urine, fever, or itching) to immediately stop treatment with FILSPARI and seek medical attention. If aminotransferase levels are abnormal at any time during treatment, interrupt FILSPARI and monitor as recommended.
Consider re-initiation of FILSPARI only when hepatic enzyme levels and bilirubin return to pretreatment values and only in patients who have not experienced clinical symptoms of hepatotoxicity. Avoid initiation of FILSPARI in patients with elevated aminotransferases (>3x ULN) because monitoring hepatotoxicity in these patients may be more difficult and these patients may be at increased risk for serious hepatotoxicity.
•FILSPARI REMS: Due to the risk of hepatotoxicity, FILSPARI is available only through a restricted program called the FILSPARI REMS. Prescribers, patients, and pharmacies must be enrolled in the REMS program and comply with all requirements (www.filsparirems.com).
•Embryo-Fetal Toxicity: Based on data from animal reproduction studies, FILSPARI may cause fetal harm when administered to a pregnant patient and is contraindicated during pregnancy. The available human data for ERAs do not establish the presence or absence of fetal harm related to the use of FILSPARI. Counsel patients who can become pregnant of the potential risk to a fetus. Exclude pregnancy before initiating treatment with FILSPARI. Advise patients who can become pregnant to use effective contraception prior to initiation of treatment, during treatment, and for two weeks after discontinuation of treatment with FILSPARI. Advise pre-pubertal females and/or their guardian(s) of the fetal risk and the need to use effective contraception once they reach reproductive potential. When pregnancy is detected, discontinue FILSPARI as soon as possible.
•Hypotension: Hypotension has been observed in patients treated with ARBs and ERAs and was observed in FILSPARI clinical studies. There was a greater incidence of hypotension-associated adverse events, some serious, including dizziness, in patients treated with FILSPARI compared to irbesartan. In patients at risk for hypotension, consider eliminating or adjusting other antihypertensive medications and maintaining appropriate volume status. If hypotension develops, despite elimination or reduction of other antihypertensive medications, consider a dose reduction or dose interruption of FILSPARI. A transient hypotensive response is not a contraindication to further dosing of FILSPARI, which can be given once blood pressure has stabilized.
•Acute Kidney Injury: Monitor kidney function periodically. Drugs that inhibit the renin-angiotensin system (RAS) can cause kidney injury. Patients whose kidney function may depend in part on the activity of the RAS (e.g., patients with renal artery stenosis, chronic kidney disease, severe
3

congestive heart failure, or volume depletion) may be at particular risk of developing acute kidney injury on FILSPARI. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in kidney function while on FILSPARI.
•Hyperkalemia: Monitor serum potassium periodically and treat appropriately. Patients with advanced kidney disease, taking concomitant potassium-increasing drugs (e.g., potassium supplements, potassium-sparing diuretics), or using potassium-containing salt substitutes are at increased risk for developing hyperkalemia. Dosage reduction or discontinuation of FILSPARI may be required.
•Fluid Retention: Fluid retention may occur with ERAs and has been observed in clinical studies with FILSPARI. FILSPARI has not been evaluated in patients with heart failure. If clinically significant fluid retention develops, evaluate the patient to determine the cause and the potential need to initiate or modify the dose of diuretic treatment then consider modifying the dose of FILSPARI.
Adverse Reactions
•IgAN patients receiving FILSPARI: The most common adverse reactions (≥5%) are hyperkalemia, hypotension (including orthostatic hypotension), peripheral edema, dizziness, anemia, and acute kidney injury.
•FSGS patients receiving FILSPARI: The most common adverse reactions (≥5%) are peripheral edema, hypotension (including orthostatic hypotension), hyperkalemia, dizziness, and anemia.
Drug Interactions
•Renin-Angiotensin System (RAS) Inhibitors and ERAs: Do not coadminister FILSPARI with ARBs, ERAs, or aliskiren due to increased risks of hypotension, syncope, hyperkalemia, and changes in renal function (including acute renal failure).
•Strong and Moderate CYP3A Inhibitors: Avoid concomitant use of FILSPARI with strong CYP3A inhibitors. If a strong CYP3A inhibitor cannot be avoided, interrupt FILSPARI treatment. When resuming treatment with FILSPARI, consider dose titration. Monitor blood pressure, serum potassium, edema, and kidney function regularly when used concomitantly with moderate CYP3A inhibitors. Concomitant use with a strong CYP3A inhibitor increases sparsentan exposure which may increase the risk of FILSPARI adverse reactions.
•Strong CYP3A Inducers: Avoid concomitant use with a strong CYP3A inducer. Concomitant use with a strong CYP3A inducer decreases sparsentan exposure which may reduce FILSPARI efficacy.
•Non-Steroidal Anti-Inflammatory Agents (NSAIDs), Including Selective Cyclooxygenase-2 (COX-2) Inhibitors: Monitor for signs of worsening renal function with concomitant use with NSAIDs (including selective COX-2 inhibitors). In patients with volume depletion (including those on diuretic therapy) or with impaired kidney function, concomitant use of NSAIDs (including selective COX-2 inhibitors) with drugs that antagonize the angiotensin II receptor may result in deterioration of kidney function, including possible kidney failure. These effects are usually reversible.
•CYP2B6, 2C9, and 2C19 Substrates: Monitor for efficacy of concurrently administered CYP2B6, 2C9, and 2C19 substrates and consider dosage adjustment in accordance with the Prescribing Information. Sparsentan is a weak inducer of CYP2B6 and 2C9, and a moderate inducer of 2C19. Sparsentan decreases exposure of these substrates, which may reduce efficacy related to these substrates.
•P-gp Substrates: Monitor for adverse reactions and consider dose reduction of P-gp substrates with narrow therapeutic indices when co-administered with FILSPARI. FILSPARI is a weak P-gp inhibitor and may increase plasma concentrations of P-gp substrate drugs.
•Agents Increasing Serum Potassium: Monitor serum potassium frequently in patients treated with FILSPARI and other agents that increase serum potassium. Concomitant use of FILSPARI with potassium-sparing diuretics, potassium supplements, potassium-containing salt substitutes, or other drugs that raise serum potassium levels may result in hyperkalemia.
Please see the full Prescribing Information, including BOXED WARNING, for additional Important Safety Information.
