Ultragenyx Reports First Quarter 2026 Financial Results and Corporate Update

First quarter total revenue of $136 million,

Crysvita® revenue of $93 million and Dojolvi® revenue of $18 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

GTX-102 for Angelman syndrome: New longer-term data from Phase 1/2 clinical study support durable and improving effects across multiple domains; Phase 3 data expected in the second half of 2026

NOVATO, Calif. – May 05, 2026 – 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 March 31, 2026 and reaffirmed its financial guidance for 2026.

“This is an important year for Ultragenyx with two BLAs under review and our Angelman Phase 3 readout coming soon. We have the opportunity to meaningfully accelerate our consistent commercial revenue growth over the last few years as we prepare for two potential gene therapy approvals and launches in two urgent diseases without any approved therapies,” said Emil D. Kakkis, M.D., Ph.D., chief executive officer and president of Ultragenyx. “The latest long-term GTX-102 Phase 1/2 data further support the potential of the program, as it heads toward Phase 3 results later this year.”

First Quarter 2026 Revenue Highlights and 2026 Revenue Guidance

• Total revenue in the first quarter of 2026 was $136 million. The company reaffirms its full year 2026 total revenue guidance of $730 million to $760 million, which excludes revenue from potential new product launches.

• Crysvita revenue in the first quarter of 2026 was $93 million, consistent with expected seasonality in the U.S. and Canada and ordering patterns in Brazil. The company reaffirms its full year 2026 Crysvita revenue guidance of $500 million to $520 million.

• Dojolvi revenue in the first quarter 2026 was $18 million. The company reaffirms its full year 2026 Dojolvi revenue guidance of $100 million to $110 million.

• Evkeeza® revenue in the first quarter 2026 was $18 million, driven by increased demand from new country launches and early access.

• Mepsevii® revenue in the first quarter 2026 was $7 million.

Recent Clinical Milestones and 2026 Catalysts

• GTX-102 (apazunersen) antisense oligonucleotide (ASO) for the treatment of Angelman syndrome (AS): As of a March 2026 Phase 1/2 data cut-off date, a total of 74 patients had been treated with GTX-102, with 66 patients continuing in the long-term extension (LTE) study. Phase 1/2 patients have been on continuous treatment for an average of more than three years, with some patients now in their fifth year, generally receiving the 14 mg quarterly maintenance dose. Patients have continued to show positive improvements across multiple domains and continued to gain ground developmentally. GTX-102 has maintained a consistent safety profile, sustained over multiple years of chronic treatment, while demonstrating no new cases of transient lower extremity weakness nor any other recurring drug-related serious adverse events. These updated efficacy and safety data are planned to be presented at a future scientific meeting.

The Phase 3 Aspire study, in patients with a full maternal UBE3A gene deletion, enrolled 129 patients, randomized 1:1 to GTX-102 or sham. Data from this study are expected in the second half of 2026.

Enrollment in the open-label Phase 2/3 Aurora study, evaluating GTX-102 in other genotypes and ages, began enrollment in October 2025 and is expected to complete enrollment in the second half of 2026.

• DTX401 (pariglasgene brecaparvovec) AAV8 gene therapy for the treatment of glycogen storage disease type Ia (GSDIa): In February 2026, the U.S. Food and Drug Administration (FDA) accepted for review the Biologics License Application (BLA) seeking approval of DTX401 as a treatment for GSDIa, granted the BLA Priority Review, and assigned a Prescription Drug User Fee Act (PDUFA) action date of August 23, 2026. The FDA also recently informed the company that an Advisory Committee meeting is not anticipated at this time.

• UX111 (rebisufligene etisparvovec) AAV9 gene therapy for the treatment of Sanfilippo syndrome type A (MPS IIIA): In April 2026, the FDA accepted for review the resubmitted BLA seeking accelerated approval for UX111 as a treatment for MPS IIIA. The resubmitted BLA included substantial longer-term data that were presented in February at the WORLDSymposium™ 2026 and included up to eight years of follow-up.

Item 2.02 Results of Operations and Financial Condition. On February 12, 2026, Ultragenyx Pharmaceutical Inc. (the “Company”) issued a press release announcing its financial results for the three months ended December 31, 2025 and for the year ended December 31, 2025 (the “Press Release”). A copy of the Press Release is furnished herewith as Exhibit 99.1.

Item 2.05 Costs Associated with Exit or Disposal Activities.

On February 12, 2026, the Company began implementation of a strategic restructuring plan to reduce expenses (the “Restructuring”). As part of the Restructuring, the Company is implementing a 10% workforce reduction of approximately 130 employees across the Company (the “RIF”). The Company began notifying affected employees on February 12, 2026, and expects this RIF to be substantially completed in the first half of 2026. The Company estimates that it will incur approximately $50 million in total restructuring and restructuring-related charges, consisting primarily of (i) approximately $10 million in total for employee severance payments and other employee-related costs and (ii) approximately $40 million in total for charges related to the termination of UX143 manufacturing agreements and other related activities. The Company anticipates that substantially all of these charges will be recognized during the first half of 2026. Cash payments related to the costs are expected to be made over the same period. The restructuring charges and the timing of the charges that the Company expects to incur in connection with the Restructuring are subject to a number of estimates and assumptions, and actual results may differ materially. The Company may also incur additional costs or charges not currently contemplated due to events that may occur as a result of, or that are associated with, the Restructuring.

Item 7.01 Regulation FD Disclosure.

Data from Phase 2 portion of Phase 2/3 Orbit study of UX143 On October 14, 2023, Ultragenyx Pharmaceutical Inc. (the “Company”) issued a press release announcing interim data from the Phase 2 portion of the Phase 2/3 Orbit study of UX143. The press release is attached hereto as Exhibit 99.1. Analyst Day Update On October 16, 2023, the Company issued a press release providing updates on its development pipeline, including setrusumab (UX143) for osteogenesis imperfecta (“OI”), GTX-102 for Angelman syndrome (“AS”), UX701 in Wilson disease and the rest of the Company’s gene therapy portfolio to be presented at an Analyst Day held in New York City and by webcast. The press release is attached hereto as Exhibit 99.2. Preliminary Third Quarter Revenue (unaudited) The Company’s preliminary unaudited total revenue for the third quarter of fiscal 2023 is $96 million to $100 million, preliminary unaudited Crysvita revenue for the third quarter is $74 million to $76 million and preliminary unaudited Dojolvi revenue for the third quarter is $16 million to $17 million. Third quarter Crysvita revenue in the United States was impacted by a decrease in channel inventory related to Kyowa Kirin Co., Ltd.’s (“KKC”) change from Ultragenyx labeled product to KKC’s labeled product as part of the transition of North America commercialization responsibilities for Crysvita from the Company to KKC. This one-time change occurred in the third quarter, and the Company expects Crysvita channel inventories to increase to more normal levels at the end of the year. Preliminary Third Quarter Ending Cash Position (unaudited) Cash, cash equivalents, and marketable debt securities were approximately $525 million as of September 30, 2023. These amounts are preliminary, have not been audited and are subject to change pending completion of the Company’s unaudited financial statements for the quarter ended September 30, 2023. Additional information and disclosures would be required for a more complete understanding of the Company’s financial position and results of operations as of September 30, 2023. The Company’s independent registered public accounting firm has not audited, reviewed or performed any procedures with respect to these preliminary results and, accordingly, does not express an opinion or any other form of assurance about them.
