Key Takeaways Ultragenyx Pharmaceutical's phase III Aspire study failed its primary and key secondary endpoints.The study found no meaningful efficacy differences in cognition or MDRI response incorporating five domains.RARE will assess apazunersen's future and plans major cost cuts while supporting its commercial business. Ultragenyx Pharmaceutical (RARE - Free Report) stock is down 46% in premarket trading today after the company reported that the late-stage study evaluating its investigational antisense oligonucleotide candidate, apazunersen (GTX-102), for Angelman syndrome (AS) failed to achieve the key goals.
The phase III Aspire study enrolled 129 patients aged four to 17 years with a genetically confirmed diagnosis of AS involving a full maternal UBE3A gene deletion. Patients were randomized equally to receive either apazunersen through an intrathecal injection via lumbar puncture or a sham procedure. Treatment consisted of three monthly 8 mg loading doses followed by a maintenance regimen increasing to a maximum quarterly dose of 14 mg of the candidate. The study assessed outcomes over 48 weeks.
Detailed Results From RARE's Phase III AS StudyUltragenyx’s phase III Aspire study failed to demonstrate a meaningful treatment benefit of apazunersen on its primary endpoint, which measured the change from baseline in the Bayley-4 cognitive raw score. RARE also reported that the study missed its key secondary endpoint of net response on the Multidomain Responder Index (MDRI). The MDRI incorporates five areas considered relevant to AS – cognition, receptive communication, behavior, gross motor function and sleep.
Year to date, RARE stock has gained 15.3% compared with the industry’s 9.7% growth.

Per Ultragenyx, the randomized treatment and control groups were comparable at baseline and consistent with the population previously evaluated in phase II. However, no differences between the groups supported efficacy on Bayley-4 cognition or the MDRI. RARE further reported that there were no meaningful differences in either net response or mean changes across the five individual MDRI domains. At the same time, the safety profile of apazunersen observed in the Aspire study remained consistent with that seen in earlier phase I/II development.
AS is a rare neurogenetic disorder associated with loss of function of the maternally inherited UBE3A gene. The disorder can cause severe cognitive and motor impairment, balance problems, seizures, limited speech, anxiety and sleep disturbances, while individuals generally require lifelong care. Per RARE, AS is estimated to affect approximately 60,000 people in commercially accessible geographies. There are no currently approved therapies for this indication.
Following the setback, Ultragenyx will evaluate the apazunersen program and decide its future disposition. The company also plans to assess its operations and implement significant expense reductions while maintaining support for its commercial business. RARE currently markets Crysvita for X-linked hypophosphatemia and tumor-induced osteomalacia, Dojolvi for long-chain fatty-acid oxidation disorders, Evkeeza for homozygous familial hypercholesterolemia (under partnership with Regeneron), Mepsevii for mucopolysaccharidosis type VII and the newly approved Genglycos (DTX401) for glycogen storage disease type Ia.

Ultragenyx Pharmaceutical Inc. (NASDAQ:RARE) stock is tumbling on Thursday after reporting late-stage clinical trial failures for its Angelman syndrome therapy, apazunersen, prompting the biopharmaceutical firm to review the program’s future and plan significant corporate expense reductions.
Understanding Apazunersen And Angelman SyndromeApazunersen is an investigational intrathecal antisense oligonucleotide therapy designed to inhibit UBE3A-AS expression.
Angelman syndrome is a rare neurogenetic disorder caused by loss-of-function in the maternally inherited UBE3A gene allele. The condition causes cognitive and motor impairments, balance issues, and seizures.
Phase 3 Trial Fails Primary And Secondary EndpointsThe company’s Phase 3 Aspire study evaluated apazunersen, also designated as GTX-102, in patients with Angelman syndrome.

Data showed that the trial missed its primary endpoint, which measured the change from baseline in the Bayley-4 cognitive raw score.
The Bayley-4 measures developmental functioning and potential delays in infants and toddlers from 16 days to 42 months old.
The drug also failed its key secondary endpoint of net response on the Multidomain Responder Index, an analysis tool to capture a broader assessment of clinical benefit.
Randomized treatment groups remained comparable at baseline, mirroring patient demographics from Phase 2 trials.
However, comparisons between treated and control groups revealed no efficacy differences in Bayley Cognition raw scores or net response across the five individual endpoints included in the responder index.
Apazunersen maintained a safety profile consistent with earlier Phase 1/2 testing.
Corporate Restructuring And Strategic ReviewFollowing the trial results, management plans to evaluate the apazunersen program to determine its ultimate disposition.
Ultragenyx will also assess operations to implement significant expense reductions while supporting its growing commercial business.
RARE Price Action: Ultragenyx Pharmaceutical shares were down 47.57% at $13.91 during premarket trading on Thursday. The stock is trading at a new 52-week low, according to Benzinga Pro data.

Market News and Data brought to you by Benzinga APIs
CompaniesSept 3 (Reuters) - Shares of Ultragenyx Pharmaceutical (RARE.O), opens new tab plunged more than 40% in premarket on Thursday after its neurodevelopmental disorder treatment failed a closely watched late-stage trial, dealing a major blow to one of its biggest growth bets.
The drug, apazunersen, failed to meet both its main goal of improving cognitive skills and its secondary goals of overall patient response in participants with Angelman syndrome, a rare condition that affects the nervous system and impairs typical brain development in childhood.
Sign up here.
Ultragenyx said there were no differences between patients receiving the treatment and those on placebo, prompting a review of the program's future.
The trial outcome is a major blow to the company and the patient community, as there are currently no approved disease-modifying treatments for the condition.
It also marks Ultragenyx's second consecutive late-stage trial failure, a setback Jefferies analyst Maury Raycroft called "unambiguously negative" and likely to "further erode street confidence".
Following the trial results, at least five brokerages slashed their price targets on the stock.
TD Cowen analysts said the failure "removes a key growth driver," while Cantor Fitzgerald analyst Kristen Kluska warned that Ultragenyx "truly has to lower its spend substantially for investors to want to even consider building a position".
Ultragenyx said it will implement "significant expense reductions" to manage its high operating costs.
Jefferies noted Ultragenyx's trial failure "raises risk for competitors" like Ionis Pharmaceuticals (IONS.O), opens new tab and Oak Hill Bio who are developing similar treatments.
"The investment case has changed shape," Leerink Partners analyst Joseph Schwartz said, arguing that Ultragenyx is now "a commercial and expense story rather than a pipeline execution story."
As of Wednesday's close, Ultragenyx stock was up 15.4% year-to-date, with a market value of $2.62 billion, according to LSEG data.

Phase 3 Aspire did not achieve the primary endpoint of change from Baseline in Bayley-4 cognitive raw score nor the key secondary endpoint of net response in Multidomain Responder Index (MDRI)
NOVATO, Calif., Sept. 02, 2026 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE) today announced results from the Phase 3 Aspire study for apazunersen (GTX-102) in Angelman syndrome. The study did not achieve the primary endpoint of change from Baseline in Bayley-4 cognitive raw score nor the key secondary endpoint of net response in Multidomain Responder Index (MDRI). The safety profile observed in Aspire was consistent with Phase 1/2.
“Based on everything we observed in the robust Phase 1/2 clinical development program and long-term extension study, we are disappointed by the Aspire result,” said Emil Kakkis, M.D., Ph.D., chief executive officer and president of Ultragenyx. “Even more, we are disappointed for the global patient community who has invested so much in early-stage research, working to bring a first-ever treatment to their children.”
In Aspire, the randomized groups were comparable at baseline and consistent with the patients studied in Phase 2. There were no differences between the treated and control groups that could support efficacy in the Bayley Cognition raw scores nor in the MDRI when looking at net response or mean changes of the individual five endpoints included in the MDRI.
The Company will evaluate the apazunersen program in light of this outcome and make a decision on its disposition. The Company will also assess its planned operations to define and implement significant expense reductions, while supporting its growing commercial business.
Dr. Kakkis continued: “We will maintain focus on our growing commercial business, which continues to create meaningful value, including new sources of revenue from the recent approval of GENGLYCOS for glycogen storage disease type Ia, the potential approval of UX111 for Sanfillipo syndrome, and the expansion of existing products to new territories. This strong commercial foundation will support our pipeline, while continuing toward profitability in 2027.”
About apazunersen (GTX-102)
Apazunersen (GTX-102) is an investigational antisense oligonucleotide (ASO) therapy delivered via intrathecal administration and designed to target and inhibit expression of the UBE3A-AS to prevent silencing of the paternally inherited allele of the UBE3A gene and reactivate expression of the deficient protein. Apazunersen has been granted Breakthrough Therapy Designation, Orphan Drug Designation, Rare Pediatric Disease Designation, and Fast Track Designation from the FDA and Orphan Designation and PRIME designation from the EMA.
About Angelman Syndrome
Angelman syndrome is a rare, neurogenetic disorder caused by loss-of-function of the maternally inherited allele of the UBE3A gene. The maternal-specific inheritance pattern of Angelman syndrome is due to genomic imprinting of UBE3A in neurons of the central nervous system (CNS), a naturally occurring phenomenon in which the maternal UBE3A allele is expressed and the paternal UBE3A is not. Silencing of the paternal UBE3A allele is regulated by the UBE3A-AS, the intended target of apazunersen. In almost all cases of Angelman syndrome, the maternal UBE3A allele is either missing or mutated, resulting in limited to no protein expression. This condition is generally not inherited but instead occurs spontaneously. It is estimated to affect approximately 60,000 people in commercially accessible geographies.
Angelman syndrome is a lifelong neurodevelopmental disorder that causes cognitive impairment, motor impairment, balance issues and debilitating seizures. Some individuals with Angelman syndrome are unable to walk and most do not speak. Anxiety and disturbed sleep can be serious challenges in individuals with Angelman syndrome. Although individuals with Angelman syndrome have a normal lifespan, they require continuous care and are unable to live independently. Angelman syndrome is not a degenerative disorder, but the loss of the UBE3A protein expression in neurons results in abnormal communications between neurons. Angelman syndrome is often misdiagnosed as autism or cerebral palsy. There are no currently approved therapies for Angelman syndrome; however, several symptoms of this disorder can be reversed in adult animal models of Angelman syndrome, suggesting that improvement of symptoms can potentially be achieved at any age.

Ultragenyx Pharmaceutical (RARE.O) said on Wednesday its experimental drug for a rare genetic neurodevelopmental disorder did not meet the main goal in a late-stage trial, sending its shares down 40% in aftermarket trading.
The drug, apazunersen, was tested as a treatment for Angelman syndrome, a condition that affects the nervous system and impairs typical brain development.
It occurs in about 1 in 15,000 live births. The condition is usually caused by a loss of function in the UBE3A gene on the 15th chromosome, specifically the copy inherited from the mother.
In the trial, the drug did not show meaningful improvement on a test of young children's cognitive and nonverbal reasoning abilities or on an overall measure of response across multiple developmental areas.
At Week 96, participants across treatment and crossover groups experienced mean reduction in daily cornstarch intake of 61% while maintaining glycemic control, with most participants achieving reduction of at least 50%
Complete elimination of nighttime cornstarch dosing observed in 33% of DTX401 treatment group and 42% of crossover group, while maintaining glycemic control
Analyses at Week 48 showed that 83% of DTX401-treated participants met or exceeded their own expectations for meaningful cornstarch reduction
NOVATO, Calif., Sept. 01, 2026 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE) today announced the publication of 96-week data from its Phase 3 study of GENGLYCOS™ AAV gene therapy (pariglasgene brecaparvovec-opnr), also known as DTX401, for the treatment of glycogen storage disease type Ia (GSDIa) in The Journal of Inherited Metabolic Disease. GENGLYCOS was recently approved by the U.S. Food and Drug Administration (FDA) in patients ages eight and older with GSDIa.
“These results demonstrate the potential of gene therapy to provide greater stability in day-to-day life for patients with GSDIa and may help guard against the risk of severe hypoglycemia associated with missed doses of raw cornstarch," said Dr. John Mitchell, scientist in the Child Health and Human Development Program at the Research Institute of the McGill University Health Centre (The Institute), pediatric endocrinologist at the Montreal Children’s Hospital, lead author of the publication and an investigator on the study. “For me, the reduction in overnight cornstarch dosing will have the most meaningful impact by reducing sleep disruption, with patient-reported outcomes included in the publication underscoring the profound impact that cornstarch reductions may have on daily life. I view long-term outcomes from the 96-week period showing continued improvements as particularly important, offering valuable insight into how post-treatment management may continue to evolve and improve as clinical experience grows."
“The complete results from this Phase 3 study more fully capture the benefits of this gene therapy and the importance of providing patients the ability to breakdown glycogen to provide a source of glucose during fasting or times of increased metabolic demands,” said Eric Crombez, M.D., chief medical officer at Ultragenyx. “Most patients achieved cornstarch reductions that met or exceeded their own expectations, with substantially less overnight treatment burden and reduced dependence on the around-the-clock cornstarch need that defines life with this disease. Importantly, reducing cornstarch dependence while maintaining glycemic control indicates the establishment of the liver’s ability to regulate glucose production on its own, giving us confidence that the therapy is directly addressing the underlying cause of disease and offering protection from the risk of life-threatening hypoglycemia.”
Authors emphasize statistically significant and clinically meaningful reductions in cornstarch while maintaining glycemic control
As previously reported, the study met its primary endpoint with patients treated with DTX401 (n=20) experiencing a mean reduction in cornstarch of 41% at Week 48 compared to 10% reduction in the placebo group (n=24) (p < 0.0001). Data at Week 96 showed even greater improvements, with both the DTX401 group (n=20) and the crossover group (n=19) achieving a mean reduction in daily cornstarch intake of 61% from baseline. Participants in both groups also experienced statistically significant improvements in other cornstarch-related endpoints.
Additionally, 72% of participants in the crossover-DTX401 group and 67% of participants in the original DTX401 group achieved reductions of at least 50% in daily cornstarch intake by Week 96. In the manuscript, the authors noted that reductions within the crossover period are particularly meaningful, as that period more closely approximates anticipated patient management in a real-world setting.
Importantly, participants maintained low levels of hypoglycemia and improved levels in euglycemic range (70-120 mg/dL) throughout the second year of the study despite substantial reductions in daily cornstarch intake. Participants dosed with DTX401 also experienced improved normalized fasting tolerance in a controlled fasting challenge (CFC) through year 2 of the study, supporting the potential for protection from severe hypoglycemia (< 54 mg/dL).
Publication offers additional insights into nighttime treatment burden
The publication provides detailed analyses of nighttime cornstarch use, one of the most burdensome aspects of current GSDIa management.
Among participants requiring nighttime cornstarch at baseline:
At Week 48, 50% of DTX401-treated participants eliminated at least one nighttime cornstarch dose compared with 7% of placebo-treated participants (p=0.031).At Week 96, 67% of participants in both treatment groups eliminated at least one nighttime cornstarch dose.By Week 96, 33% of original DTX401 participants and 42% of crossover-DTX401 participants had completely eliminated nighttime cornstarch dosing. Despite substantial reductions in daily and nighttime cornstarch use, participants maintained glycemic control throughout the study, without inducing severe hypoglycemic episodes. These findings build upon previously reported reductions in nighttime cornstarch requirements and provide additional insight into the impact of DTX401 on overnight disease management.
Patient-reported outcomes support treatment effect as clinically meaningful
Authors detailed findings of a patient-centered analysis that showed the average reduction in daily cornstarch intake considered meaningful by participants at baseline was 45%. At Week 48, 83% of DTX401-treated participants met or exceeded their own baseline expectations for meaningful reduction in cornstarch use, with continued improvements through Week 96.
At Week 48, 79% of DTX401-treated participants reported improvement in GSDIa on the Patient Global Impression of Change compared with 52% of placebo-treated participants (p=0.131); at Week 96, improvement was reported by 95% of crossover-DTX401 participants and 83% of original DTX401 participants.
The publication further characterizes how reducing cornstarch requirements affected overall nutritional management. At baseline, cornstarch accounted for nearly 50% of study participants’ total caloric intake. Following treatment with DTX401, participants were able to transition to a more balanced, food-based diet closer to the U.S. Dietary Guidelines for the general population.
DTX401 was generally well tolerated with an acceptable safety profile
Consistent with previously reported findings, the authors concluded that DTX401 demonstrated an acceptable and manageable safety profile. The most common treatment-related adverse events were transient elevations in liver enzymes, which were generally nonserious and managed with prophylactic corticosteroids.
No AAV8 class effects of dorsal root ganglion toxicity, malignancy, or thrombotic microangiopathy were observed in the study through Week 96. Hypertriglyceridemia was observed in all study groups but more frequently following DTX401 treatment.

Hepatotoxicity
Immune-mediated hepatotoxicity, with elevated alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) levels, has occurred with GENGLYCOS. Avoid use in patients with preexisting hepatic impairment or acute hepatic viral infection.Prior to GENGLYCOS infusion, evaluate liver-related medical history and assess liver function by clinical examination and laboratory testing. Advise patients to immediately report signs and symptoms of hepatotoxicity, including fatigue, jaundice, dark urine, nausea, vomiting, and right upper quadrant pain. Administer corticosteroids to all patients after GENGLYCOS infusion in order to mitigate hepatic reactions. Elevated transaminases may require adjustment of the corticosteroid treatment regimen, including increased dose or prolongation of the corticosteroid taper.Monitor transaminase levels for the first 6 months after GENGLYCOS administration. Continue to monitor transaminases in all patients who develop transaminase elevations, until transaminases return to baseline or as clinically indicated. Adrenal Insufficiency
Adrenal insufficiency, including serious events, has been reported in patients receiving GENGLYCOS during corticosteroid use and tapering.Signs and symptoms of adrenal insufficiency include fatigue, weakness, anorexia, nausea, vomiting, hypotension, hyponatremia, and hypoglycemia. Adrenal crisis may present as severe hypotension, acute abdominal pain, or loss of consciousness.Monitor patients for signs and symptoms of adrenal insufficiency and adrenal crisis after GENGLYCOS administration during and after corticosteroid therapy and tapering. Taper corticosteroid therapy gradually. Do not abruptly discontinue corticosteroid therapy. AAV Vector Integration and Risk of Tumorigenicity
There is a theoretical risk of tumorigenicity due to integration of AAV vector DNA into the genome.GENGLYCOS is composed of a recombinant, non-replicating AAV8 vector whose DNA persists largely in episomal form. Random integration of recombinant AAV-vector DNA into human DNA has been reported with AAV gene therapies. The clinical relevance of individual integration events is unknown, but it is acknowledged that individual integration events could potentially contribute to a risk of tumorigenicity. If a tumor develops in a patient receiving GENGLYCOS, health care providers should contact and report the tumor to Ultragenyx Pharmaceutical Inc. at 1-888-756-8657. Adverse Reactions
Seven serious adverse events were observed in the Primary Efficacy Analysis Period (PEAP) of Study 1 (Weeks 1-48), including anaphylaxis/infusion reaction (2), adrenal insufficiency (2), high lactate level (2) and hypoglycemia (1).The most common adverse reactions during the PEAP of Study 1 (occurring in ≥10% of patients) with higher frequency in GENGLYCOS compared to placebo were ALT/AST Enzyme elevated (71%), Nausea (38%), Headache (24%), Hypertriglyceridemia (29%), Adrenal Insufficiency (24%), Constipation (19%), Hyperglycemia (14%), Acne/Dermatitis Acneiform (19%), Cushingoid Features (14%), and Anaphylaxis (10%). DRUG INTERACTIONS
Vaccinations
Vaccine schedules may need to be adjusted for immunosuppressive therapy, and vaccines should be avoided 1 month prior to GENGLYCOS administration. USE IN SPECIFIC POPULATIONS
Pregnancy
GENGLYCOS should not be used during pregnancy. There are no data on the use of GENGLYCOS in pregnant women. It is unknown whether GENGLYCOS can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Contraception
Women of childbearing potential should use effective contraception for at least 12 months after administration of GENGLYCOS.For 6 months after administration of GENGLYCOS, men must not donate semen, and men of reproductive potential and their female partners must prevent or postpone pregnancy using an effective form of contraception. ADDITIONAL PATIENT COUNSELING INFORMATION
Vector Shedding
Inform patients/caregivers that vector distribution in blood and vector shedding in urine, stool, and saliva can occur after GENGLYCOS infusion. Advise patients/caregivers on proper hygiene when handling patient body waste. These precautions should be followed for 3 months after GENGLYCOS infusion. Report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088. You may also report side effects to Ultragenyx Pharmaceutical Inc. at 1-888-756-8657.

About the Phase 3 GlucoGene study
The 48-week randomized, double-blind, placebo-controlled study treated 46 participants aged eight years and older with DTX401 (1.0 x 10^13 GC/kg dose measured by ddPCR) or placebo. There were 44 participants in the modified intention-to-treat (mITT) population providing efficacy data within the Week 48 analysis period following treatment with DTX401 (n=20) or placebo (n=24). At Week 48, eligible participants crossed over and received the alternate treatment. After crossover, participants continued to be followed with analyses conducted at Week 96 and Week 144. After study completion, participants will be offered enrollment into the GSDIa Disease Monitoring Program (DMP) where they will be followed for 10 years post-DTX401 infusion.
About Glycogen Storage Disease Type Ia (GSDIa)
GSDIa is an ultra-rare, serious, and life-threatening disease due to an inborn error of carbohydrate metabolism caused by pathogenic variants of the G6PC gene, which encodes G6Pase, an enzyme that is critical for the release of glucose from glycogen and other metabolic sources. Deficiency of G6Pase activity results in severe hypoglycemia during periods of fasting between meals and during the night along with excess hepatic glycogen storage, metabolic derangements and other disease related complications. Cornstarch is critical in the management of GSDIa throughout the day and night in providing an exogenous source of glucose to help avoid sudden and severe drops in plasma glucose levels; however, current management strategies carry a significant burden to patients and families. GSDIa affects approximately 1,500-2,500 patients in the U.S. and 6,000-8,000 worldwide within commercially accessible geographies.

Key Takeaways Ultragenyx won FDA accelerated approval for Genglycos, its first gene therapy and fifth approved product.Genglycos significantly cut daily cornstarch needs in phase III, easing the burden of GSDIa management.The accelerated approval requires Ultragenyx to provide longer-term safety and efficacy data. Shares of Ultragenyx Pharmaceutical (RARE - Free Report) are rising in premarket trading today following the FDA’s accelerated approval of DTX-401, an AAV8 gene therapy for glycogen storage disease type Ia (GSDIa).
The therapy will be marketed in the United States as Genglycos (pariglasgene brecaparvovec-opnr) and is indicated to reduce daily cornstarch intake as an adjunct to nutritional management in adult and pediatric patients aged eight years and older with GSDIa. The approval makes Genglycos the first FDA-approved treatment designed to address the underlying cause of GSDIa and marks Ultragenyx’s first gene therapy approval and its fifth FDA approval overall.
FDA Nod for RARE’s Genglycos Supported by Phase III DataThe accelerated approval of Ultragenyx’s Genglycos is supported by results from the 48-week phase III GlucoGene study, which enrolled 46 participants aged eight years and older. Treatment with the drug produced a statistically significant reduction in daily cornstarch requirements compared with placebo. Patients were subsequently crossed over to the alternate treatment and continued to be monitored in longer-term follow-up.
Under the accelerated approval, Ultragenyx is required to provide additional safety and efficacy data through an enhanced GSDIa Disease Monitoring Program. The company will follow 50 commercially treated patients and 20 control patients for two years, while the broader monitoring program will continue to evaluate patients for up to 10 years. Continued approval for the indication may depend on confirmation of clinical benefit in post-marketing studies.
Year to date, shares of Ultragenyx have gained 14.1% compared with the industry’s 7% growth.

RARE’s Genglycos May Ease the GSDIa Treatment BurdenGSDIa is an ultra-rare inherited metabolic disorder caused by pathogenic variants in the G6PC gene. These variants lead to a deficiency of glucose-6-phosphatase, an enzyme required for the release of glucose from stored glycogen and other metabolic sources. As a result, patients can experience severe hypoglycemia during fasting, including overnight, along with excess glycogen accumulation in the liver and other metabolic complications.
The condition affects an estimated 1,500-2,500 patients in the United States and 6,000-8,000 globally within commercially accessible geographies. Existing management relies on strict, around-the-clock supplementation with raw cornstarch to help maintain blood glucose levels. Even with strict adherence, interruptions in treatment can expose patients to severe hypoglycemia, seizures and potentially life-threatening complications, making the disease particularly burdensome for patients and caregivers.
Against this backdrop, the FDA decision is significant because Ultragenyx’s Genglycos is designed to address the underlying biological defect in GSDIa rather than manage its metabolic consequences. By delivering a functional G6PC gene to the liver, the therapy aims to restore the enzyme’s role in glucose production during fasting or metabolic stress, potentially reducing patients’ reliance on intensive cornstarch supplementation and easing the day-to-day burden of glucose management.
Genglycos Expands RARE’s Approved Product PortfolioFollowing the FDA nod, Genglycos becomes the fifth FDA-approved therapy in Ultragenyx’s portfolio, adding to four established products. Crysvita (burosumab-twza) is approved in the United States for X-linked hypophosphatemia in adults and pediatric patients and for tumor-induced osteomalacia. Mepsevii (vestronidase alfa-vjbk) is approved for mucopolysaccharidosis type VII, while Dojolvi (triheptanoin) is approved for long-chain fatty acid oxidation disorders.
The fourth product, Evkeeza (evinacumab-dgnb), is indicated for homozygous familial hypercholesterolemia. Ultragenyx holds rights to develop, commercialize and distribute Evkeeza outside the United States, while Regeneron Pharmaceuticals commercializes the drug in the United States. This makes Genglycos a particularly important addition to Ultragenyx’s directly marketed U.S. portfolio, further diversifying its commercial base across rare and ultra-rare diseases.

Analysts Say These 2 Mid-Cap Biotechs Have 2x PotentialUltragenyx Pharmaceutical NASDAQ: RARE said the U.S. Food and Drug Administration has approved GENGLYCOS, also known as DTX401, for glycogen storage disease type 1A, or GSD1A. The approval marks the company’s first gene therapy approval and its fifth approved medicine.
GENGLYCOS is indicated for adults and pediatric patients ages 8 and older with GSD1A who do not have antibodies to AAV8. The liver-directed gene therapy is designed to address the underlying cause of the disease by enabling the liver to break down glycogen and produce glucose during fasting or metabolic stress, according to the company.
Get RARE alerts:
Emil Kakkis, Ultragenyx’s chief executive officer and president, said the treatment provides a new option for patients who have historically relied on cornstarch slurry every three to four hours, including overnight, to help avoid life-threatening hypoglycemia.
Accelerated Approval and Confirmatory Data The FDA granted GENGLYCOS accelerated approval after deciding late in its review to consider reduced cornstarch use as a surrogate endpoint. Ultragenyx will need to generate additional evidence showing that the reduction is associated with clinical benefit and improved fasting tolerance over time.
The biologics license application was supported by a Phase 3 randomized, double-blind, placebo-controlled study involving 46 patients ages 8 and older. The study met its primary endpoint, showing a statistically significant reduction in daily cornstarch intake versus placebo while maintaining glycemic control, Ultragenyx said. The company also reported positive results across multiple secondary endpoints.
Eric Crombez, chief medical officer, said the broader clinical program includes 52 treated patients and up to eight years of follow-up. GENGLYCOS was well tolerated, according to the company, with transient liver-enzyme elevations representing the most common treatment-related events. Those events were generally non-serious and managed with a prophylactic corticosteroid regimen.
As part of its post-marketing commitment, Ultragenyx plans to collect two years of data from 50 commercially treated patients through its disease monitoring program. The program will assess daily cornstarch intake and time to hypoglycemia during a controlled fasting challenge. The company will also follow 20 untreated patients with AAV8 antibodies as a control group.
The two-year evaluation will be conducted in an open-label setting, allowing patients and physicians to receive real-time glucose measurements. Ultragenyx said it believes this structure could enable greater cornstarch reduction and improved metabolic control than a blinded study without real-time glucose information.
Commercial Launch Plans Erik Harris, chief commercial officer, said Ultragenyx has established UltraCare Gene Therapy Guides to help patients navigate insurance coverage, treatment support and questions related to the gene therapy process. GENGLYCOS will be administered through a national network of qualified treatment centers selected for GSD1A and gene therapy experience.
The company said it has enough treatment centers under contract to meet initial demand and expects the network could double by year-end. It plans to continue adding centers as demand grows. Ultragenyx said roughly 75% of GSD1A providers overlap with physicians it already knows through its MEPSEVII and DOJOLVI commercial activities.
Ultragenyx set a U.S. wholesale acquisition cost of $2.7 million per patient for GENGLYCOS. The company expects initial access to proceed through single-case agreements while insurers develop coverage policies. Management said it has had extensive discussions with state Medicaid programs and large national payers, which have recognized the severity of GSD1A and the potential clinical relevance of reduced cornstarch dependence.
Management expects GENGLYCOS to be commercially available within 30 to 60 days, subject to final steps in the product-release process. The company did not provide a launch revenue forecast, citing the need to first assess reimbursement processes and market dynamics.
Manufacturing, Revenue Outlook and Priority Review Voucher GENGLYCOS is manufactured entirely in-house at Ultragenyx’s Bedford, Massachusetts, gene therapy facility. The company said it has commercial inventory to meet anticipated demand and will scale production as the launch progresses.
Howard Horn, chief financial officer, said Ultragenyx intends to provide revenue guidance once it has sufficient visibility into market dynamics, which historically has been about six quarters after launch. In the meantime, the company expects to report measures including treatment-center network growth and the number of patients treated.
Ultragenyx also received a priority review voucher with the approval and plans to monetize the voucher to support its balance sheet and path to profitability. Horn said the company has previously discussed an average net-pricing range of $1 million to $2 million and expects GENGLYCOS net pricing to be at or near the upper end of that range.
Beyond the U.S., Ultragenyx said it has filed or plans to file in other territories and expects to pursue commercialization globally, though it did not provide specific regulatory timelines. Management said pricing and reimbursement pressure may differ outside the U.S., but the company sees potential for substantial revenue in international markets as well.

The reduced reliance on cornstarch, experienced by patients in our clinical studies, demonstrates this gene therapy’s ability to establish the normal breakdown of glycogen to produce glucose during fasting or episodes of metabolic stress. This ability to regulate glucose has alleviated the disease burden and has the potential to mitigate the risk of severe or life-threatening hypoglycemia for these patients,” said Eric Crombez, M.D., chief medical officer at Ultragenyx. “As our first gene therapy approval, GENGLYCOS represents an important achievement for our company and the realization of the promise of a powerful new tool to deliver transformative medicines for people living with rare diseases.”
GSDIa is an ultra-rare genetic metabolic disorder caused by a deficiency of the enzyme needed to release glucose from the liver to the bloodstream. The deficiency reduces the liver’s ability to control glucose levels and is associated with potentially life-threatening hypoglycemia episodes and other serious complications, requiring rigorous nutritional management that involves a burdensome, around-the-clock regimen of raw cornstarch intake as an oral glucose replacement therapy. Glucose control with cornstarch is crude with large swings in glucose, and patients instead end up spending a large fraction of their day significantly hyperglycemic to avoid hypoglycemic episodes. GSDIa affects 1,500-2,500 patients in the U.S. and 6,000-8,000 worldwide within commercially accessible geographies.
“Day-to-day management of GSDIa requires a relentless regimen of raw cornstarch and strict dietary management that can be extraordinarily demanding for patients and families. Even with meticulous adherence to this regimen, patients must be perfect. Any missed cornstarch puts patients at risk of severe hypoglycemia, seizures, and even death,” said David Weinstein, M.D., MMSc, one of the world's leading GSDIa experts. “The approval of GENGLYCOS represents a major step forward for the GSDIa community and reflects almost 30 years of work and scientific progress aimed at improving safety and the quality of life of people living with this disease.”
“For families affected by GSDIa, every day revolves around strict schedules, overnight vigilance, and the constant worry that a missed meal or dose of cornstarch could trigger life-threatening hypoglycemia,” said David and Wendy Feldman, co-founders and current Board members at The Children’s Fund for Glycogen Storage Disease Research. “This approval is an incredibly meaningful milestone for a community that has spent decades hoping, advocating, and helping advance the research for new treatment options that could ease the burdens of this disease.”
Clinical Program and Post-Marketing Study Requirements Supporting Accelerated Approval of GENGLYCOS
The approval of GENGLYCOS is based on positive data from the 48-week randomized, double-blind, placebo-controlled Phase 3 GlucoGene study which treated 46 participants aged eight years and older with DTX401 (1.0 x 10^13 GC/kg dose) or placebo, showing a reduction in the cornstarch requirements in the treated group (p<0.001). There were 44 participants in the modified intention-to-treat (mITT) population providing efficacy data within the Week 48 analysis period following treatment with DTX401 (n=20) or placebo (n=24). At Week 48, eligible participants crossed over and received the alternate treatment. After crossover, participants continued to be followed, with analyses conducted at Week 96 and Week 144.
As part of accelerated approval, Ultragenyx has agreed to provide two years of safety and efficacy clinical data from open-label commercial treatment of 50 patients and 20 control patients through enhancement of its existing GSDIa Disease Monitoring Program (DMP). The control group will consist of patients who sought commercial treatment but cannot be treated with GENGLYCOS due to the presence of anti-AAV8 antibodies. The study will provide more data to support the reduction in cornstarch clinical burden, fasting tolerance, and other measures in a post-marketing setting where patients can know their immediate glucose levels, and their cornstarch and diet can be managed more promptly by their physician. The DMP will also evaluate previously treated clinical trial participants as well as these new commercial patients for a total of 10 years.
Enabling Access for Eligible Patients
Ultragenyx will provide support to help enrolled patients and caregivers navigate access to treatment through its UltraCare® program, which now includes specially trained UltraCare® Gene Therapy Guides to help understand insurance coverage, assist in obtaining treatment support, and answer questions about the treatment process. Dedicated in-house UltraCare Gene Therapy Guides are available Monday through Friday from 9 a.m. to 8 p.m. Eastern Time at 888-756-8657. More information is available at www.ultracaresupport.com.
GENGLYCOS will be available through a national network of Qualified Treatment Centers (QTCs) with specialized expertise and training to safely administer gene therapy.
GENGLYCOS is manufactured entirely at Ultragenyx’s Gene Therapy Manufacturing Facility (GTMF) in Bedford, Mass., strengthening the Company’s ability to scale production of high-quality gene therapy products and deliver them to patients as efficiently as possible.
More information will be available at www.genglycos.com.

This indication is approved under accelerated approval based on reduction in daily cornstarch intake. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trial(s).
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS
GENGLYCOS is contraindicated in patients with known severe hepatic fibrosis or cirrhosis.
WARNINGS AND PRECAUTIONS
Hypersensitivity and Infusion Reactions (IRs)
Hypersensitivity reactions including anaphylaxis and IRs have occurred with GENGLYCOS treatment. Severe reactions have been reported. Monitor for signs and symptoms of hypersensitivity and IRs, including urticaria, flushing, hypotension, bronchospasm, dyspnea, chest tightness, nausea, vomiting, headache, abdominal pain, lightheadedness, flu-like symptoms, shivering, rash, and hypertension.Premedicate with acetaminophen and non-sedating antihistamines and administer GENGLYCOS according to recommended infusion rates. Monitor patients during and after completion of GENGLYCOS infusion as clinically indicated. If anaphylaxis or severe IR occurs, pause GENGLYCOS infusion immediately and initiate medical treatment as clinically indicated, monitoring as needed. For mild to moderate IRs, consider slowing or temporarily interrupting the infusion, and administer symptomatic treatment as clinically indicated. The infusion may be restarted at half the prior rate upon resolution of symptoms.Medical support measures, including cardiopulmonary resuscitation equipment and medications for the treatment of anaphylaxis (e.g., epinephrine, antihistamines, corticosteroids), should be available during GENGLYCOS administration.
Hepatotoxicity
Immune-mediated hepatotoxicity, with elevated alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) levels, has occurred with GENGLYCOS. Avoid use in patients with preexisting hepatic impairment or acute hepatic viral infection.Prior to GENGLYCOS infusion, evaluate liver-related medical history and assess liver function by clinical examination and laboratory testing. Advise patients to immediately report signs and symptoms of hepatotoxicity, including fatigue, jaundice, dark urine, nausea, vomiting, and right upper quadrant pain. Administer corticosteroids to all patients after GENGLYCOS infusion in order to mitigate hepatic reactions. Elevated transaminases may require adjustment of the corticosteroid treatment regimen, including increased dose or prolongation of the corticosteroid taper.Monitor transaminase levels for the first 6 months after GENGLYCOS administration. Continue to monitor transaminases in all patients who develop transaminase elevations, until transaminases return to baseline or as clinically indicated.
Adrenal Insufficiency
Adrenal insufficiency, including serious events, has been reported in patients receiving GENGLYCOS during corticosteroid use and tapering.Signs and symptoms of adrenal insufficiency include fatigue, weakness, anorexia, nausea, vomiting, hypotension, hyponatremia, and hypoglycemia. Adrenal crisis may present as severe hypotension, acute abdominal pain, or loss of consciousness.Monitor patients for signs and symptoms of adrenal insufficiency and adrenal crisis after GENGLYCOS administration during and after corticosteroid therapy and tapering. Taper corticosteroid therapy gradually. Do not abruptly discontinue corticosteroid therapy.
AAV Vector Integration and Risk of Tumorigenicity
There is a theoretical risk of tumorigenicity due to integration of AAV vector DNA into the genome.GENGLYCOS is composed of a recombinant, non-replicating AAV8 vector whose DNA persists largely in episomal form. Random integration of recombinant AAV-vector DNA into human DNA has been reported with AAV gene therapies. The clinical relevance of individual integration events is unknown, but it is acknowledged that individual integration events could potentially contribute to a risk of tumorigenicity. If a tumor develops in a patient receiving GENGLYCOS, health care providers should contact and report the tumor to Ultragenyx Pharmaceutical Inc. at 1-888-756-8657. Adverse Reactions
Seven serious adverse events were observed in the Primary Efficacy Analysis Period (PEAP) of Study 1 (Weeks 1-48), including anaphylaxis/infusion reaction (2), adrenal insufficiency (2), high lactate level (2) and hypoglycemia (1).The most common adverse reactions during the PEAP of Study 1 (occurring in ≥10% of patients) with higher frequency in GENGLYCOS compared to placebo were ALT/AST Enzyme elevated (71%), Nausea (38%), Headache (24%), Hypertriglyceridemia (29%), Adrenal Insufficiency (24%), Constipation (19%), Hyperglycemia (14%), Acne/Dermatitis Acneiform (19%), Cushingoid Features (14%), and Anaphylaxis (10%). DRUG INTERACTIONS
Vaccinations
Vaccine schedules may need to be adjusted for immunosuppressive therapy, and vaccines should be avoided 1 month prior to GENGLYCOS administration.
USE IN SPECIFIC POPULATIONS

About Glycogen Storage Disease Type Ia (GSDIa)
GSDIa is an ultra-rare, serious, and life-threatening disease due to an inborn error of carbohydrate metabolism caused by pathogenic variants of the G6PC gene, which encodes G6Pase, an enzyme that is critical for the release of glucose from glycogen and other metabolic sources. Deficiency of G6Pase activity results in severe hypoglycemia during periods of fasting between meals and during the night along with excess hepatic glycogen storage, metabolic derangements, and other disease-related complications. Cornstarch is critical in the management of GSDIa throughout the day and night in providing an exogenous source of glucose to help avoid sudden and severe drops in plasma glucose levels; however, current management strategies carry a significant burden to patients and families. GSDIa affects 1,500-2,500 patients in the U.S. and 6,000-8,000 worldwide within commercially accessible geographies.

Ultragenyx Pharmaceutical (RARE.O) said on Wednesday that its gene therapy became the first to receive the U.S. Food and Drug Administration's approval to treat a rare metabolic disorder, sending its shares up 7.5% in after-hours trading.
The drug, branded as Genglycos, has been approved for glycogen storage disease type Ia (GSDIa), also known as Von Gierke disease, in adults and pediatric patients.
It is an ultra-rare genetic disorder that is caused due to deficiency of an enzyme that helps release glucose from the liver into the bloodstream. GSDIa affects 1,500 to 2,500 patients in the U.S., the company estimates.
The deficiency reduces the liver's ability to control glucose levels and is associated with potentially life-threatening low blood sugar levels.
Day-to-day management of the condition requires a relentless regimen of raw cornstarch as an oral glucose replacement therapy.
Ultragenyx's Genglycos addresses the underlying cause of the disorder by aiding the normal breakdown of glycogen to produce glucose, which helps in regulating blood sugar levels and reducing reliance on cornstarch.
Genglycos will have a U.S. per-patient list price of $2.7 million and be available through qualified treatment centers within 30 to 60 days, the company said.
The regulator's authorization is based on a 48-week late-stage trial that found patients treated with Genglycos showed a reduction in the cornstarch requirements compared to placebo.
Reducing cornstarch intake is, however, the surrogate endpoint, and the manufacturer must complete additional clinical trials to confirm Genglycos's effectiveness, the FDA said.
The company said it has agreed to provide two years of safety and efficacy clinical data from patients.
Several experimental treatments for GSDIa are also in development, including those from Moderna (MRNA.O) and Beam Therapeutics (BEAM.O), though the candidates remain in early stages of clinical testing.
Ultragenyx Pharmaceutical is rated a soft Buy at $26.75, with a probability-weighted fair value of ~$32 per share. Two near-term FDA decisions: DTX401 on Aug 23 and another for UX111 on Sept 19. DTX401 has a cleaner regulatory case, but UX111 has a credible approval path. Using 80% approval odds for DTX401 and 65% for UX111, our probability-weighted value is approximately $32 per share versus a current share price near $27.

Key Takeaways RARE beat Q2 earnings estimates as revenues rose 28% year over year to a record quarterly high.Crysvita, Dojolvi and Evkeeza sales grew on demand, supporting higher product revenues.Ultragenyx reaffirmed 2026 revenue guidance of $730M-$760M, excluding new product launches. Ultragenyx Pharmaceutical (RARE - Free Report) reported second-quarter 2026 loss of 90 cents per share, which was narrower than the Zacks Consensus Estimate of a loss of $1.27. The company had incurred a loss of $1.17 per share in the year-ago quarter.
Total revenues in the second quarter were $214 million, which surged 28.1% year over year due to higher product sales. The top line also beat the Zacks Consensus Estimate of $181 million.
Management stated that second-quarter 2026 revenues were the highest quarterly revenues ever reported by the company.
Ultragenyx markets four drugs, namely Crysvita, Mepsevii, Dojolvi and Evkeeza. Crysvita is approved for treating X-linked hypophosphatemia, an inherited disorder and tumor-induced osteomalacia, an ultra-rare disease. Mepsevii is approved to treat Mucopolysaccharidosis VII, also known as Sly syndrome. Dojolvi is approved for treating all forms of long-chain fatty acid oxidation disorders. Evkeeza is indicated for homozygous familial hypercholesterolemia (HoFH).
In 2022, Ultragenyx announced a license and collaboration agreement with Regeneron Pharmaceuticals (REGN - Free Report) for Evkeeza, which is approved in multiple geographies as a first-in-class therapy for use together with diet and other low-density lipoprotein-cholesterol-lowering therapies to treat adults and adolescents aged 12 years and older with HoFH.
Per the deal, RARE has obtained the rights to develop, commercialize and distribute Evkeeza outside the United States. The regions include the European Economic Area. The collaboration with Regeneron for Evkeeza gives Ultragenyx a fourth approved product that adds to the top line. However, REGN solely commercializes Evkeeza in the United States.
Year to date, shares of Ultragenyx have gained 12.2% compared with the industry’s 1.6% rise.

RARE’s Q2 Results in DetailCrysvita’s total revenues were $156 million, up 28.9% year over year. Management noted that Crysvita sales were consistent with expected seasonality in the United States and Canada and ordering patterns in Latin America. Crysvita’s net product revenues in the second quarter of 2026 included $94 million from North America, $54 million from Latin America and Turkey, and $8 million from Europe.
Mepsevii product revenues increased 11.1% year over year to $10 million in the reported quarter. Dojolvi product revenues were $27 million, up 17.4%, driven by strong demand. Evkeeza recorded sales of $21 million in the second quarter, up 50%, driven by increased demand from new country launches and early access.
Operating expenses of $289 million in the quarter rose 5.1% year over year due to increased investments in multiple late-stage pipeline programs and marketing costs for approved drugs. Operating expenses included research and development (R&D) expenses of $167 million (up 1.2%), selling, general and administrative (SG&A) expenses of $88 million (up 1.1%) and cost of sales of $34 million (up 47.8%).
Cash, cash equivalents and marketable securities amounted to $436 million as of June 30, 2026, compared with $534 million as of March 31, 2026.
RARE Reiterates 2026 Financial GuidanceUltragenyx continues to expect total revenues in 2026, excluding potential revenues from new product launches, between $730 million and $760 million.
Crysvita revenues in 2026 are expected to be in the range of $500-$520 million, reflecting growing underlying global demand. Meanwhile, Dojolvi revenues are expected to be between $100 million and $110 million in 2026.
RARE’s Key Pipeline UpdatesIn April 2026, the FDA accepted the resubmitted biologics license application (BLA) seeking accelerated approval of UX111 for the treatment of MPS IIIA. The application included extensive long-term data with follow-up of up to eight years. The data showed sustained clinical benefits compared with the decline seen in natural history studies, along with durable treatment effects across multiple clinical measures and biomarkers, while maintaining an acceptable safety profile. A final decision from the regulatory body is expected on Sept. 19, 2026.
The FDA has also accepted for review Ultragenyx’s BLA for its investigational AAV8 gene therapy, DTX401, to treat glycogen storage disease type Ia. A final decision from the regulatory agency is expected on Aug. 23, 2026.
Ultragenyx is also evaluating UX701, an investigational AAV9 gene therapy, in a phase I/II/III Cyprus2+ study to treat Wilson disease and expects to share top-line data in the fourth quarter of 2026.
Ultragenyx’s GTX-102, an investigational antisense oligonucleotide, is being developed in the pivotal phase III Aspire study for treating Angelman syndrome (AS) patients with a genetically confirmed diagnosis of UBE3A deletion. Top-line data are expected in September or October 2026. Meanwhile, enrollment in the phase II/III Aurora study is currently ongoing to evaluate the safety and efficacy of GTX-102 for treating other AS genotypes in other patient age groups. This additional study aims to enable treatment for a broader range of AS patients. The study is expected to complete enrollment in the second half of 2026.

Good afternoon and welcome to the Ultragenyx Second Quarter 2026 Financial Results Conference Call.
[Operator Instructions]
It is now my pleasure to turn the call over to Joshua Higa, Chief of Staff and Vice President of Investor Relations.
Joshua Higa
Director of Investor Relations & Corporate Communications
Thank you. We have issued a press release detailing our financial results, which you can find on our website at ultragenyx.com. Joining me on this call are Emil Kakkis, Chief Executive Officer and President; Howard Horn, Chief Financial Officer; Erik Harris, Chief Commercial Officer; and Eric Crombez, Chief Medical Officer.
I'd like to remind everyone that during today's call, we will be making forward-looking statements. These statements are subject to certain risks
Ultragenyx (RARE - Free Report) came out with a quarterly loss of $0.9 per share versus the Zacks Consensus Estimate of a loss of $1.27. This compares to a loss of $1.17 per share a year ago. These figures are adjusted for non-recurring items.
This quarterly report represents an earnings surprise of +29.13%. A quarter ago, it was expected that this biotechnology company would post a loss of $1.55 per share when it actually produced a loss of $1.84, delivering a surprise of -18.71%.
Over the last four quarters, the company has surpassed consensus EPS estimates just once.
Ultragenyx, which belongs to the Zacks Medical - Biomedical and Genetics industry, posted revenues of $214 million for the quarter ended June 2026, surpassing the Zacks Consensus Estimate by 18.23%. This compares to year-ago revenues of $166.5 million. The company has topped consensus revenue estimates two times over the last four quarters.
The sustainability of the stock's immediate price movement based on the recently-released numbers and future earnings expectations will mostly depend on management's commentary on the earnings call.
Ultragenyx shares have added about 8.8% since the beginning of the year versus the S&P 500's gain of 11%.
What's Next for Ultragenyx?While Ultragenyx has underperformed the market so far this year, the question that comes to investors' minds is: what's next for the stock?
There are no easy answers to this key question, but one reliable measure that can help investors address this is the company's earnings outlook. Not only does this include current consensus earnings expectations for the coming quarter(s), but also how these expectations have changed lately.
Empirical research shows a strong correlation between near-term stock movements and trends in earnings estimate revisions. Investors can track such revisions by themselves or rely on a tried-and-tested rating tool like the Zacks Rank, which has an impressive track record of harnessing the power of earnings estimate revisions.
Ahead of this earnings release, the estimate revisions trend for Ultragenyx was favorable. While the magnitude and direction of estimate revisions could change following the company's just-released earnings report, the current status translates into a Zacks Rank #2 (Buy) for the stock. So, the shares are expected to outperform the market in the near future. You can see the complete list of today's Zacks #1 Rank (Strong Buy) stocks here.
It will be interesting to see how estimates for the coming quarters and the current fiscal year change in the days ahead. The current consensus EPS estimate is -$0.85 on $189.98 million in revenues for the coming quarter and -$4.53 on $746.71 million in revenues for the current fiscal year.
Investors should be mindful of the fact that the outlook for the industry can have a material impact on the performance of the stock as well. In terms of the Zacks Industry Rank, Medical - Biomedical and Genetics is currently in the top 42% of the 250 plus Zacks industries. Our research shows that the top 50% of the Zacks-ranked industries outperform the bottom 50% by a factor of more than 2 to 1.
One other stock from the same industry, Zealand Pharma A/S (ZLDPF - Free Report) , is yet to report results for the quarter ended June 2026. The results are expected to be released on August 13.
This company is expected to post quarterly loss of $0.42 per share in its upcoming report, which represents a year-over-year change of -102.6%. The consensus EPS estimate for the quarter has remained unchanged over the last 30 days.
Zealand Pharma A/S's revenues are expected to be $81.55 million, down 94.1% from the year-ago quarter.
Ultragenyx (RARE - Free Report) reported $214 million in revenue for the quarter ended June 2026, representing a year-over-year increase of 28.5%. EPS of -$0.90 for the same period compares to -$1.17 a year ago.
The reported revenue compares to the Zacks Consensus Estimate of $181.01 million, representing a surprise of +18.23%. The company delivered an EPS surprise of +29.13%, with the consensus EPS estimate being -$1.27.
While investors scrutinize revenue and earnings changes year-over-year and how they compare with Wall Street expectations to determine their next move, some key metrics always offer a more accurate picture of a company's financial health.
As these metrics influence top- and bottom-line performance, comparing them to the year-ago numbers and what analysts estimated helps investors project a stock's price performance more accurately.
Here is how Ultragenyx performed in the just reported quarter in terms of the metrics most widely monitored and projected by Wall Street analysts:
Revenues- Dojolvi: $27 million compared to the $25.61 million average estimate based on five analysts. The reported number represents a change of +16.3% year over year.Revenues- Evkeeza: $21 million versus the five-analyst average estimate of $17.43 million. The reported number represents a year-over-year change of +44.1%.Revenues- Mepsevii: $10 million compared to the $9.75 million average estimate based on five analysts. The reported number represents a change of +20.3% year over year.Revenues- Product sales: $112 million versus the four-analyst average estimate of $98.68 million. The reported number represents a year-over-year change of +38.6%.Revenues- Total Crysvita Revenue: $156 million versus the four-analyst average estimate of $128.3 million.

Shares of Ultragenyx have returned -25.8% over the past month versus the Zacks S&P 500 composite's +1.7% change. The stock currently has a Zacks Rank #2 (Buy), indicating that it could outperform the broader market in the near term.
Analysts Say These 2 Mid-Cap Biotechs Have 2x PotentialUltragenyx Pharmaceutical NASDAQ: RARE reported second-quarter 2026 revenue of $214 million, led by growth across its commercial rare-disease portfolio, while the company prepared for potential regulatory decisions on two gene therapies and a late-stage data readout in Angelman syndrome.
Chief Executive Officer and President Emil Kakkis said the quarter marked the company’s highest quarterly revenue to date and supported its reaffirmed full-year revenue guidance. He also said Ultragenyx sees a path to profitability in 2027 through continued product growth, potential contributions from upcoming launches, expense discipline and possible monetization of priority review vouchers.

Second-Quarter Financial Results Chief Financial Officer Howard Horn said total second-quarter revenue reached $214 million. Crysvita generated $156 million, including $94 million in North America, $54 million in Latin America and Turkey, and $8 million in Europe. DOJOLVI contributed $27 million, while Evkeeza generated $21 million, up 50% from the second quarter of 2025. MEPSEVII revenue was $10 million.
Total operating expenses were $289 million, including $34 million in cost of sales and $255 million in combined research and development and selling, general and administrative expenses. Operating expenses included $34 million of non-cash stock-based compensation.
Ultragenyx posted a net loss of $92 million, or $0.90 per share, for the quarter. As of June 30, the company had $436 million in cash equivalents and marketable securities. Net cash used in operations was $97 million, which Horn said was significantly lower than in the first quarter and in line with prior expectations.
The company reaffirmed its revenue guidance and its guidance for combined R&D and SG&A expenses. Horn said 2026 combined R&D and SG&A spending is expected to be flat to down low single digits from 2025, while 2027 spending is expected to decline by at least 15%, including planned investments for potential launches.
Commercial Portfolio Expands Patient Reach Chief Commercial Officer Erik Harris said underlying demand remained strong despite seasonal factors that can affect quarterly ordering patterns. In Latin America, approximately 50 patients began commercial Crysvita therapy during the quarter, bringing the regional total to 1,000 patients. More than 100 patients in Turkey are receiving Crysvita through a named-patient program.
For DOJOLVI, Ultragenyx generated about 30 start forms in North America and had approximately 675 patients on reimbursed treatment. About 300 patients in Europe were receiving treatment through named-patient or early-access programs. The company also began treating patients in Japan after the therapy was listed on the country’s National Health Insurance Drug Price List.
Evkeeza was being provided to more than 500 patients in 25 countries outside the U.S., Harris said. He added that Ultragenyx’s commercial infrastructure is designed to support patient identification, reimbursement navigation and field execution across individual markets.
Gene Therapy Decisions Approach Ultragenyx is awaiting FDA action on DTX-401, an investigational gene therapy for glycogen storage disease type Ia, with a Prescription Drug User Fee Act date of Aug. 23. The company’s second anticipated decision is for UX-111, a gene therapy for Sanfilippo syndrome type A, with a PDUFA date of Sept. 19.
Kakkis said DTX-401 clinical studies showed that treated patients could significantly reduce the amount and frequency of cornstarch dosing to a prespecified clinically meaningful degree. He said the therapy is designed to provide expression of the missing G6Pase enzyme and improve glucose regulation during fasting or metabolic stress.
For UX-111, Kakkis said clinical data showed reductions in heparan sulfate and stabilization or retention of cognitive function relative to natural history. He said earlier treatment appeared to produce better results, although patients across the age range studied showed benefits after treatment.
Harris said launch preparations for the two potential gene therapies were progressing, including work with qualified treatment centers and more than 200 payer engagements. He said the company already has commercial experience in relevant treatment settings, with approximately 75% overlap between institutions and healthcare providers involved with the potential gene therapies and those serving DOJOLVI and MEPSEVII patients.
During the question-and-answer session, Kakkis said the FDA review of DTX-401 had proceeded normally, with the company responding to information requests involving clinical and chemistry, manufacturing and controls matters. He said Ultragenyx could not predict the agency’s ultimate action.
Angelman Readout and Setrusumab Regulatory Path Ultragenyx expects to report top-line Phase III ASPIRE data for GTX-102, also known as apazunersen, in Angelman syndrome during September or October. The randomized, double-blind, sham-controlled study enrolled patients with a full maternal UBE3A gene deletion.
Chief Medical Officer Eric Crombez said the study’s statistical alpha is split between the Bayley-4 cognitive raw score, which receives 80%, and the Multi-Domain Responder Index, or MDRI, which receives 20%. The endpoints are tested in parallel rather than hierarchically. A statistically successful study would require a Bayley endpoint p-value of 0.04 or less, or an MDRI p-value of 0.01 or less.
Kakkis said a five- to six-point change on the Bayley assessment would be clinically meaningful and that the study was powered to detect an average change in that range. He also said the company’s Phase I/II program has shown a consistent safety profile, and the Phase III study had not been stopped because of a safety issue.
Separately, Ultragenyx continues discussions with regulators regarding UX143, or setrusumab, for osteogenesis imperfecta. Crombez said neither of the Phase III ORBIT and COSMIC studies met their primary endpoints for annualized fracture reduction, though the studies showed improvements in bone mineral density and patient-reported outcomes, along with fracture reductions in certain bones and patient groups.
The U.K.’s Medicines and Healthcare products Regulatory Agency indicated that a new randomized study may be required before it would consider an application, according to Crombez. The FDA has been open to discussing alternative fracture analyses, but Ultragenyx said further discussions are needed to determine the additional clinical data required for a potential biologics license application.

Second quarter total revenue of $214 million, Crysvita® revenue of $156 million and Dojolvi® revenue of $27 million Reaffirm 2026 financial guidance, including total revenue of $730 million to $760 million and combined R&D and SG&A expenses to be flat to slightly down versus 2025; remain on path to profitability in 2027 Catalysts in second half of 2026 include two PDUFA dates and pivotal data readout from GTX-102 Phase 3 Aspire study for Angelman syndrome NOVATO, Calif., Aug. 04, 2026 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE), a biopharmaceutical company focused on the development and commercialization of novel therapies for serious rare and ultra-rare genetic diseases, today reported its financial results for the quarter ended June 30, 2026 and reaffirmed its financial guidance for 2026.
NOVATO, Calif., July 28, 2026 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE), a biopharmaceutical company focused on the development and commercialization of novel products for serious rare and ultra-rare genetic diseases, today announced that it will host a conference call at 5:00 p.m. ET on Tuesday, August 4, 2026, to discuss its financial results and corporate update for the quarter ending June 30, 2026.
Ultragenyx (RARE - Free Report) is expected to deliver a year-over-year decline in earnings on higher revenues when it reports results for the quarter ended June 2026. This widely-known consensus outlook gives a good sense of the company's earnings picture, but how the actual results compare to these estimates is a powerful factor that could impact its near-term stock price.
The stock might move higher if these key numbers top expectations in the upcoming earnings report. On the other hand, if they miss, the stock may move lower.
While management's discussion of business conditions on the earnings call will mostly determine the sustainability of the immediate price change and future earnings expectations, it's worth having a handicapping insight into the odds of a positive EPS surprise.
Zacks Consensus EstimateThis biotechnology company is expected to post quarterly loss of $1.27 per share in its upcoming report, which represents a year-over-year change of -8.6%.
Revenues are expected to be $181.01 million, up 8.7% from the year-ago quarter.
Estimate Revisions TrendThe consensus EPS estimate for the quarter has remained unchanged over the last 30 days. This is essentially a reflection of how the covering analysts have collectively reassessed their initial estimates over this period.
Investors should keep in mind that an aggregate change may not always reflect the direction of estimate revisions by each of the covering analysts.
Price, Consensus and EPS Surprise
Earnings WhisperEstimate revisions ahead of a company's earnings release offer clues to the business conditions for the period whose results are coming out. Our proprietary surprise prediction model -- the Zacks Earnings ESP (Expected Surprise Prediction) -- has this insight at its core.
The Zacks Earnings ESP compares the Most Accurate Estimate to the Zacks Consensus Estimate for the quarter; the Most Accurate Estimate is a more recent version of the Zacks Consensus EPS estimate. The idea here is that analysts revising their estimates right before an earnings release have the latest information, which could potentially be more accurate than what they and others contributing to the consensus had predicted earlier.
Thus, a positive or negative Earnings ESP reading theoretically indicates the likely deviation of the actual earnings from the consensus estimate. However, the model's predictive power is significant for positive ESP readings only.
A positive Earnings ESP is a strong predictor of an earnings beat, particularly when combined with a Zacks Rank #1 (Strong Buy), 2 (Buy) or 3 (Hold). Our research shows that stocks with this combination produce a positive surprise nearly 70% of the time, and a solid Zacks Rank actually increases the predictive power of Earnings ESP.
Please note that a negative Earnings ESP reading is not indicative of an earnings miss. Our research shows that it is difficult to predict an earnings beat with any degree of confidence for stocks with negative Earnings ESP readings and/or Zacks Rank of 4 (Sell) or 5 (Strong Sell).
How Have the Numbers Shaped Up for Ultragenyx?For Ultragenyx, the Most Accurate Estimate is lower than the Zacks Consensus Estimate, suggesting that analysts have recently become bearish on the company's earnings prospects. This has resulted in an Earnings ESP of -5.27%.
On the other hand, the stock currently carries a Zacks Rank of #2.
So, this combination makes it difficult to conclusively predict that Ultragenyx will beat the consensus EPS estimate.
Does Earnings Surprise History Hold Any Clue?Analysts often consider to what extent a company has been able to match consensus estimates in the past while calculating their estimates for its future earnings. So, it's worth taking a look at the surprise history for gauging its influence on the upcoming number.
For the last reported quarter, it was expected that Ultragenyx would post a loss of$1.55 per share when it actually produced a loss of -$1.84, delivering a surprise of -18.71%.
Over the last four quarters, the company has beaten consensus EPS estimates just once.
Bottom LineAn earnings beat or miss may not be the sole basis for a stock moving higher or lower. Many stocks end up losing ground despite an earnings beat due to other factors that disappoint investors. Similarly, unforeseen catalysts help a number of stocks gain despite an earnings miss.
That said, betting on stocks that are expected to beat earnings expectations does increase the odds of success. This is why it's worth checking a company's Earnings ESP and Zacks Rank ahead of its quarterly release. Make sure to utilize our Earnings ESP Filter to uncover the best stocks to buy or sell before they've reported.
Ultragenyx doesn't appear a compelling earnings-beat candidate. However, investors should pay attention to other factors too for betting on this stock or staying away from it ahead of its earnings release.
An Industry Player's Expected ResultsAnother stock from the Zacks Medical - Biomedical and Genetics industry, CRISPR Therapeutics AG (CRSP - Free Report) , is soon expected to post loss of $1.1 per share for the quarter ended June 2026. This estimate indicates a year-over-year change of +14.7%. Revenues for the quarter are expected to be $7.42 million, up 733.7% from the year-ago quarter.
The consensus EPS estimate for CRISPR Therapeutics has been revised 0.8% lower over the last 30 days to the current level. However, a higher Most Accurate Estimate has resulted in an Earnings ESP of +1.94%.
When combined with a Zacks Rank of #3 (Hold), this Earnings ESP indicates that CRISPR Therapeutics will most likely beat the consensus EPS estimate. Over the last four quarters, the company surpassed consensus EPS estimates two times.

LEADING EDGE MATERIALS ADVANCES MIDSTREAM PROCESSING STRATEGY FOR THE NORRA KÄRR HEAVY RARE EARTH ELEMENTS PROJECT
Initiative launched to enhance Norra Kärr’s flowsheet with collaboration on new hydrometallurgical research in support of future pilot plant establishment. Swedish Government funding secured: two projects involving the company awarded funding through Vinnova, the Swedish Innovation agency, as part of a SEK 70+ million (CAD 10 million) national push to secure Sweden's critical raw materials supply.Path to concentrate production: Domain sampling now underway to generate high-grade eudialyte concentrate, the essential feedstock for upcoming hydrometallurgical pilot testing.On track to develop the EU’s first heavy rare earth elements mine following the grant of Norra Kärr’s 25-year mining lease in June 2026 Vancouver, July 20,2 026 - Leading Edge Materials Corp. ("Leading Edge Materials" or the "Company") (TSXV: LEM) (Nasdaq First North: LEMSE) (OTCQB: LEMIF) (FRA: 7FL) is pleased to provide an update on its midstream processing strategy for eudialyte concentrate from the Norra Kärr Heavy Rare Earth Elements ("HREE") Project – and the path toward pilot-scale hydrometallurgical testing, a key step in demonstrating the process at commercial scale. This builds on the significant flowsheet development work completed over the last 15 years, and new research into silicate management under the Vinnova-funded SHLENK project.
Eudialyte Processing
Eudialyte is recognised globally as one of the most promising mineral sources of heavy rare earth elements, with projects in Greenland and Australia being developed in addition to Norra Kärr in Sweden. With eudialyte, the behaviour of silicates during leaching needs to be managed to prevent gel formation. Two well-known approaches are dilution, reducing silicate concentrations through sufficient dilution during leaching and inhibiting gel formation, and pre-treatment, treating the eudialyte concentrate ahead of leaching to prevent silicate release during dissolution, while preserving rare earth element solubility. Studies have demonstrated that under correctly selected pretreatment conditions for a given source material, silicate leaching can be effectively prevented. The pre-treatment option was used in the Company's 2021 Preliminary Economic Assessment ("PEA") and current project development workstreams are focused on performance and cost optimisation, and upscaling studies.
Pilot-Scale Hydrometallurgical Testing
The pre-treatment approach has shown strong results in laboratory-scale testing for Norra Kärr material and an extended pilot is intended to further strengthen hydrometallurgical understanding. To achieve optimal pilot data, a new high-grade eudialyte concentrate will be produced. Over the summer, the Company is conducting a domain sampling programme using the existing drill core library. This will be followed by further mineral processing to produce eudialyte concentrate while also generating valuable nepheline syenite as co-product for customer trials.
Consistent with the design set out in the Company’s 2021 PEA, mineral processing at Norra Kärr will only feature crushing, grinding, and magnetic separation; the eudialyte concentrate would then be transported to a midstream hydrometallurgical facility at a separate, established industrial location – keeping the footprint at Norra Kärr small and placing chemical processing where infrastructure already exists.
New Innovation Research: The SHLENK Project
The pilot work programme will benefit from research into improved processing methods, including through the Company's collaboration with RISE (Research Institutes of Sweden) under the SEK 1.5 million (CAD 0.2 million) funded SHLENK project – "Silicate management in leaching of eudialyte from Norra Kärr”.
SHLENK is one of two research projects involving the Company’s wholly owned Swedish subsidiary, Greenna Mineral AB, that have recently been granted funding by the Swedish Government through Vinnova's Impact Innovation call, "Resilient metals and minerals supply for strengthened preparedness," alongside the NordAL (Nordic Alumina) project.
Together with 17 other projects, these initiatives form part of a national effort to strengthen Sweden's metals and minerals supply chain in peacetime, during heightened preparedness, and in times of crisis. The combined programme represents more than SEK 70 million (approximately CAD 10 million) in funding, of which approximately SEK 42 million (CAD 6 million) is provided by Vinnova.
For the Company, this funding represents strong recognition of the strategic importance of its work at Norra Kärr and its contribution to building a more resilient and secure supply chain for critical raw materials in Sweden and the Nordics.
The work is carried out within Swedish Metals & Minerals, a joint initiative by the Swedish Energy Agency, Formas, and Vinnova under the framework of Impact Innovation.
Kurt Budge, Chief Executive Officer, commented:
“Following the grant of the 25-year mining lease, our work continues towards developing Norra Kärr, the EU's first heavy rare earth elements mine.
Progressing with our Pre-feasibility Study, we continue to de-risk and enhance the processing flowsheet for Norra Kärr. We have a clear plan: working with the best eudialyte concentrate, verifying our pre-treatment approach to silicate management, and generating the data we need to run at pilot scale.
Heavy rare earths like dysprosium and terbium are foundational to the technologies driving electrification and defence readiness across Europe, and Norra Kärr remains one of the continent's richest deposits. The support from Vinnova is a strong validation of the strategic role Norra Kärr can play in strengthening Sweden's and Europe's resilience in critical raw materials."
About the Norra Kärr Project
Norra Kärr is one of Europe's most significant deposits of heavy rare earth elements, hosted in an eudialyte-bearing alkaline rock body in southern Sweden. The project's strategic value is underpinned by its high dysprosium and terbium ("Dy/Tb") content, critical inputs for permanent magnets used in electric vehicles, wind turbines, and defence applications.
On 28 June 2026, an Exploitation Concession – 25-year mining lease - was granted by the Swedish Government following a formal recommendation from the Mining Inspectorate (Sw. Bergsstaten), which submitted the application to the Government for a final decision after all involved agencies had either endorsed the application or recommended approval.
The strategic importance of heavy rare earth elements to Europe's industrial future has never been more apparent. As China's export controls have demonstrated, access to dysprosium, terbium and yttrium cannot be taken for granted — and the consequences of supply disruption are severe. Norra Kärr, now holding an Exploitation Concession, is key to addressing Europe’s critical risk exposure.
Edison estimates current European dysprosium demand at 180-200 tpa of Dy₂O₃. Norra Kärr's 2021 PEA discloses average annual Dy₂O₃ production of 248t, which Edison notes is "similar to European consumption."

Wall Street expects a year-over-year increase in earnings on higher revenues when Ultragenyx (RARE - Free Report) reports results for the quarter ended March 2026. While this widely-known consensus outlook is important in gauging the company's earnings picture, a powerful factor that could impact its near-term stock price is how the actual results compare to these estimates.
The earnings report might help the stock move higher if these key numbers are better than expectations. On the other hand, if they miss, the stock may move lower.
While management's discussion of business conditions on the earnings call will mostly determine the sustainability of the immediate price change and future earnings expectations, it's worth having a handicapping insight into the odds of a positive EPS surprise.
Zacks Consensus EstimateThis biotechnology company is expected to post quarterly loss of $1.55 per share in its upcoming report, which represents a year-over-year change of +1.3%.
Revenues are expected to be $161.26 million, up 15.8% from the year-ago quarter.
Estimate Revisions TrendThe consensus EPS estimate for the quarter has been revised 5.07% higher over the last 30 days to the current level. This is essentially a reflection of how the covering analysts have collectively reassessed their initial estimates over this period.
Investors should keep in mind that the direction of estimate revisions by each of the covering analysts may not always get reflected in the aggregate change.
Price, Consensus and EPS Surprise
Earnings WhisperEstimate revisions ahead of a company's earnings release offer clues to the business conditions for the period whose results are coming out. This insight is at the core of our proprietary surprise prediction model -- the Zacks Earnings ESP (Expected Surprise Prediction).
The Zacks Earnings ESP compares the Most Accurate Estimate to the Zacks Consensus Estimate for the quarter; the Most Accurate Estimate is a more recent version of the Zacks Consensus EPS estimate. The idea here is that analysts revising their estimates right before an earnings release have the latest information, which could potentially be more accurate than what they and others contributing to the consensus had predicted earlier.
Thus, a positive or negative Earnings ESP reading theoretically indicates the likely deviation of the actual earnings from the consensus estimate. However, the model's predictive power is significant for positive ESP readings only.
A positive Earnings ESP is a strong predictor of an earnings beat, particularly when combined with a Zacks Rank #1 (Strong Buy), 2 (Buy) or 3 (Hold). Our research shows that stocks with this combination produce a positive surprise nearly 70% of the time, and a solid Zacks Rank actually increases the predictive power of Earnings ESP.
Please note that a negative Earnings ESP reading is not indicative of an earnings miss. Our research shows that it is difficult to predict an earnings beat with any degree of confidence for stocks with negative Earnings ESP readings and/or Zacks Rank of 4 (Sell) or 5 (Strong Sell).
How Have the Numbers Shaped Up for Ultragenyx?For Ultragenyx, the Most Accurate Estimate is lower than the Zacks Consensus Estimate, suggesting that analysts have recently become bearish on the company's earnings prospects. This has resulted in an Earnings ESP of -0.05%.
On the other hand, the stock currently carries a Zacks Rank of #3.
So, this combination makes it difficult to conclusively predict that Ultragenyx will beat the consensus EPS estimate.
Does Earnings Surprise History Hold Any Clue?Analysts often consider to what extent a company has been able to match consensus estimates in the past while calculating their estimates for its future earnings. So, it's worth taking a look at the surprise history for gauging its influence on the upcoming number.
For the last reported quarter, it was expected that Ultragenyx would post a loss of$1.2 per share when it actually produced a loss of -$1.29, delivering a surprise of -7.50%.
Over the last four quarters, the company has beaten consensus EPS estimates just once.
Bottom LineAn earnings beat or miss may not be the sole basis for a stock moving higher or lower. Many stocks end up losing ground despite an earnings beat due to other factors that disappoint investors. Similarly, unforeseen catalysts help a number of stocks gain despite an earnings miss.
That said, betting on stocks that are expected to beat earnings expectations does increase the odds of success. This is why it's worth checking a company's Earnings ESP and Zacks Rank ahead of its quarterly release. Make sure to utilize our Earnings ESP Filter to uncover the best stocks to buy or sell before they've reported.
Ultragenyx doesn't appear a compelling earnings-beat candidate. However, investors should pay attention to other factors too for betting on this stock or staying away from it ahead of its earnings release.
An Industry Player's Expected ResultsAmong the stocks in the Zacks Medical - Biomedical and Genetics industry, Grail (GRAL - Free Report) , is soon expected to post loss of $3 per share for the quarter ended March 2026. This estimate indicates a year-over-year change of +3.2%. This quarter's revenue is expected to be $40.47 million, up 27.1% from the year-ago quarter.
Over the last 30 days, the consensus EPS estimate for Grail has remained unchanged. Nevertheless, the company now has an Earnings ESP of -2.67%, reflecting a lower Most Accurate Estimate.
When combined with a Zacks Rank of #3 (Hold), this Earnings ESP makes it difficult to conclusively predict that Grail will beat the consensus EPS estimate. Over the last four quarters, the company surpassed consensus EPS estimates three times.

Ultragenyx shares have added about 7.9% since the beginning of the year versus the S&P 500's gain of 5.2%.
What's Next for Ultragenyx?While Ultragenyx has outperformed the market so far this year, the question that comes to investors' minds is: what's next for the stock?
There are no easy answers to this key question, but one reliable measure that can help investors address this is the company's earnings outlook. Not only does this include current consensus earnings expectations for the coming quarter(s), but also how these expectations have changed lately.
Empirical research shows a strong correlation between near-term stock movements and trends in earnings estimate revisions. Investors can track such revisions by themselves or rely on a tried-and-tested rating tool like the Zacks Rank, which has an impressive track record of harnessing the power of earnings estimate revisions.
Ahead of this earnings release, the estimate revisions trend for Ultragenyx was mixed. While the magnitude and direction of estimate revisions could change following the company's just-released earnings report, the current status translates into a Zacks Rank #3 (Hold) for the stock. So, the shares are expected to perform in line with the market in the near future. You can see the complete list of today's Zacks #1 Rank (Strong Buy) stocks here.

Shares of Ultragenyx have returned +8.5% over the past month versus the Zacks S&P 500 composite's +9.5% change. The stock currently has a Zacks Rank #3 (Hold), indicating that it could perform in line with the broader market in the near term.
Key Takeaways Ultragenyx Q1 revenues fell 2% as Crysvita sales declined due to seasonal and ordering effects.RARE saw Evkeeza sales jump 64% on new country launches and early access demand.Ultragenyx expects FDA decisions on UX111 and DTX401 later in 2026 amid other pipeline progress. Ultragenyx Pharmaceutical (RARE - Free Report) reported first-quarter 2026 loss of $1.84 per share, wider than the Zacks Consensus Estimate of a loss of $1.55. The company had incurred a loss of $1.57 per share in the year-ago quarter.
Ultragenyx’s total revenues amounted to $136 million in the reported quarter, which declined 2% year over year due to lower product sales. The top line missed the Zacks Consensus Estimate of $161 million.
The company markets four drugs, namely Crysvita, Mepsevii, Dojolvi and Evkeeza. Crysvita is approved for treating X-linked hypophosphatemia, an inherited disorder and tumor-induced osteomalacia, an ultra-rare disease. Mepsevii is approved to treat Mucopolysaccharidosis VII, also known as Sly syndrome. Dojolvi is approved for treating all forms of long-chain fatty acid oxidation disorders. Evkeeza is indicated for homozygous familial hypercholesterolemia (HoFH).
In 2022, Ultragenyx announced a license and collaboration agreement with Regeneron Pharmaceuticals (REGN - Free Report) for Evkeeza, which is approved in multiple geographies as a first-in-class therapy for use together with diet and other low-density lipoprotein-cholesterol-lowering therapies to treat adults and adolescents aged 12 years and older with HoFH. Per the deal, RARE has obtained the rights to develop, commercialize and distribute Evkeeza outside the United States. The regions include the European Economic Area. The collaboration with Regeneron for Evkeeza gives Ultragenyx a fourth approved product that adds to the top line. However, REGN solely commercializes Evkeeza in the United States.
RARE’s Q1 Results in DetailCrysvita’s total revenues were $93 million, down 10% year over year, due to expected seasonality in the U.S. and Canada and ordering patterns in Brazil. Crysvita’s net product revenues in the first quarter of 2026 included $39 million from North America, $46 million from Latin America and Turkey, and $8 million from Europe.
Mepsevii product revenues decreased 13% year over year to $7 million in the reported quarter. Dojolvi product revenues were $18 million, up 6%, driven by new patient demand. Evkeeza recorded sales of $18 million in the first quarter, up 64%, driven by increased demand from new country launches and early access.
Year to date, shares of Ultragenyx have gained 8.7% against the industry’s 2.4% decline.

Operating expenses of $305 million in the quarter rose 8% year over year due to increased investments in multiple late-stage pipeline programs and marketing costs for approved drugs. Operating expenses included research and development (R&D) expenses of $187 million (up 13%), selling, general and administrative (SG&A) expenses of $88 million (up 1%) and cost of sales of $30 million (up 3%).
Cash, cash equivalents and marketable securities amounted to $534 million as of March 31, 2026, compared with $737 million as of Dec. 31, 2025.
RARE Reiterates 2026 Financial GuidanceUltragenyx continues to expect total revenues in 2026, excluding potential revenues from new product launches, between $730 million and $760 million, which suggests growth of approximately 8-13% compared to 2025.
Crysvita revenues in 2026 are expected to be in the range of $500-$520 million, indicating growing underlying global demand partially offset by the expected timing of ordering patterns in Brazil. On the other hand, Dojolvi revenues are expected to be between $100 million and $110 million in 2026.
RARE’s Key Pipeline UpdatesIn April 2026, the FDA accepted the resubmitted biologics license application (BLA) seeking accelerated approval of UX111 for the treatment of MPS IIIA. The application included extensive long-term data with follow-up of up to eight years. The data showed sustained clinical benefits compared with the decline seen in natural history studies, along with durable treatment effects across multiple clinical measures and biomarkers, while maintaining an acceptable safety profile. A final decision from the regulatory body is expected on Sept. 19, 2026.
Ultragenyx’s GTX-102, an investigational antisense oligonucleotide, is being developed in the pivotal phase III Aspire study for treating Angelman syndrome (AS) patients with a genetically confirmed diagnosis of UBE3A deletion. Top-line data is expected in the second half of 2026. Enrollment in the phase II/III Aurora study is currently ongoing to evaluate the safety and efficacy of GTX-102 for treating other AS genotypes in other patient age groups, with the first patient dosed in October 2025. This additional study aims to enable treatment for a broader range of AS patients.
The FDA has also accepted for review Ultragenyx’s BLA for its investigational AAV8 gene therapy, DTX401, to treat glycogen storage disease type Ia. A final decision from the FDA is expected on Aug. 23, 2026. The regulatory body also recently informed RARE that an Advisory Committee meeting is not anticipated at this time. Ultragenyx is also evaluating UX701, an investigational AAV9 gene therapy, in a phase I/II/III Cyprus2+ study to treat Wilson disease and expects to share top-line data later in 2026.

Developing a new drug can cost a billion dollars and take more than a decade. That makes investing in new treatments in the rare disease space — where patient populations are small, and the chance of earning a return on that investment even smaller — a risky bet for big pharmaceutical companies.
That's a big reason why 95% of the more than 10,000 rare diseases that exist do not have an FDA-approved treatment.
But for parents of children diagnosed with those diseases, doing nothing is not an option. And that's fueling a major trend in the rare disease community: medical innovation and breakthroughs that are being driven by the patient groups themselves.
Last October, Rare As One — a project funded by the Chan Zuckerberg Biohub that supports patient-led research in the rare disease space — released a report that showed of the 20 organizations it funded when the program launched in 2019, half of them were involved in clinical trials within five years.
That's remarkable progress from advocacy groups that are mostly led by the communities they represent – regular parents from varied backgrounds, partnering with researchers and clinicians to develop life saving treatments for their loved ones. But for many of these families, figuring out where to start that process can be incredibly complicated.
Ultragenyx, an established player in rare and ultra-rare drug development, is looking to fill that gap and provide families and patient advocates the tools and resources for discovering a treatment.
Twice a year the company hosts Rare Bootcamp, a multi-day forum that helps families learn about conducting rare disease research and the important steps that go into developing a new drug. It also lets them connect with others going through a similar experience.
The event is free for attendees, and is sponsored by other biotech firms, such as Alexion, BioMarin, GeneDx and BridgeBio, that also send experts to participate in panels.
During its most recent bootcamp in Boston last month, the company held more than 20 sessions covering the full spectrum of drug development, from early science to regulatory approval.
Ultragenyx founder and CEO Emil Kakkis launched the bootcamps nine years ago, inspired by his own difficulties researching new treatments during his early days in the industry.
"There's no book, there's no 'CliffsNotes' on how to develop a drug," Kakkis said.
"I struggled and struggled, and I promised myself at that time that if I ever became in the position that I knew how to do it, I was just going to tell everyone else that needed it," Kakkis said.
Mike and Evelyn Ribadeneyra attended the most recent bootcamp. They are trying to find a treatment for their daughter Abbie, who suffers from hereditary spastic paraplegia type 26, a progressive neurodegenerative disorder that took two decades to diagnose.
While they said they did not initially start their journey expecting to find a cure for their daughter's condition, in the past year they discovered that a gene therapy existed for a similar disorder called SPG 50.
"We've been on a long journey, but our new journey begins at rare disease boot camp," Mike Ribadeneyra said.
The Ribadeneyras came to Boston to receive a roadmap for how to convince others to conduct research on behalf of their child, and to develop a proof of concept for the drug.
"I didn't know what to expect, but it has been overwhelming. The access that we've been given to the researchers, specialists, and doctors … I feel like they're really in our community now," Evelyn said.
The event also serves as a gathering place for families and advocates navigating similar circumstances. Through networking sessions at the conference and dinners at the end of the day, attendees share tips and compare notes on their rare disease journeys.
"We felt so alone for so many years, and my daughter feels so alone … and to know that there are other people going through the exact same process is really encouraging," Mike said.
Laura Wilson attended the event to help her daughter Ellia, who was diagnosed with a rare neurodevelopmental disorder called ReNU2.
Wilson spent about nine years without a formal diagnosis for Ellia, as the gene was only identified in April 2025. She recently founded an organization called ReNU2 United to help families affected by the disease. So far, about 60 families in 17 countries have identified that their child has the disorder.
Wilson attended Ultragenyx's bootcamp to hear from experts in the room about developing treatments, and to learn best practices from other families that have used their organizations to support research.
"No one in this room has a child with the same disorder that my child has, but we share so much in common," Wilson said in an interview.
"That experience of being a parent to a child with a rare disorder is so unifying that, you know, you sort of get it right away," Wilson said.
The bootcamp, which is co-hosted by the EveryLife Foundation — an advocacy group founded by Kakkis in 2009 — has grown through word of mouth. Roughly two dozen attendees attended last month's event, and since it launched about 235 people from 142 organizations have completed the program.
It's also inspired other similar events, like the RARE Advocate Development Brain Workshop. That workshop focuses on rare diseases that attack the central nervous system, and is hosted by the Rare Epilepsy Network, Mahzi Therapeutics and the advocacy group Global Genes.
Ultimately though, Kakkis says he's looking forward to the day that these types of events will no longer be needed.
"My hope some day is that we'll fix this problem," Kakkis said. "And we'll know that it's fixed, because we won't see any more parents having to develop their own drugs. They'll all be done. That's what I'm hoping for."
