PALO ALTO, CA – October 29, 2025 – BridgeBio Pharma, Inc. (Nasdaq: BBIO) (“BridgeBio” or the “Company”), a new type of biopharmaceutical company focused on genetic diseases, today announced its financial results for the third quarter ended September 30, 2025, and provided business updates.

As of October 25, 2025, 5,259 unique patient prescriptions have been written by 1,355 unique prescribers since FDA approval in November 2024. The third quarter revenue totaled $120.7 million, comprised of $108.1 million of U.S. Attruby net product revenue, $4.3 million from royalty revenue, and $8.3 million in license and services revenue.

“Attruby’s first year on the market has been remarkable, with continued growth across all market segments and strong physician adoption that reflects both the differentiated clinical profile and the trust we’re earning within the community. We’re seeing meaningful momentum where prescribers are not only initiating more patients on therapy but continuing treatment, underscoring Attruby’s real-world impact,” said Matt Outten, Chief Commercial Officer of BridgeBio. “Importantly, this launch has also given us an invaluable blueprint for how we bring best-in-class medicines to patients with genetic diseases. With the promising results seen in BBP-418 for LGMD2I/R9 and encaleret for ADH1, we are building on a proven commercial foundation to ensure these communities, each living with urgent, unmet needs, have timely access to transformative therapies and we will apply the playbook we’ve developed to prepare for our next potential approvals.”

“Attruby’s strong commercial performance continues to validate our model, delivering a potential best-in-class medicine to patients who were historically overlooked and building meaningful momentum across all market segments,” said Neil Kumar, Ph.D., founder and CEO of BridgeBio. “We are now seeing that same success echoed in our pipeline with home-run data in both ADH1 and LGMD2I/R9, and we continue to advance one of the broadest and fastest-moving portfolios in genetic medicine.

With achondroplasia data expected in 2026, enrollment nearing completion for the Phase 2 potion of the hypochondroplasia study, and registrational studies for encaleret in chronic hypoparathyroidism and pediatric ADH1 planned next year, we are not slowing down and continue to be impatient for patients. These milestones reflect our growing scalability and strengthen our conviction that BridgeBio is only beginning to show what’s possible as we evolve into a durable, multi-medicine company built for patients with genetic diseases for decades to come.”

Attruby (acoramidis) – First near-complete (≥90%) transthyretin (TTR) stabilizer for treatment of transthyretin amyloid cardiomyopathy (ATTR-CM):

•At this year’s Heart Failure Society of America (HFSA) Annual Scientific Meeting, BridgeBio presented data from the ATTRibute-CM study showing that acoramidis reduced cumulative cardiovascular outcomes, including cardiovascular mortality (CVM) or recurrent cardiovascular-related hospitalizations (CVH), within the first month of treatment in patients with ATTR-CM. At Month 30, Acoramidis significantly reduced the cumulative risk of CVM or recurrent CVH versus placebo with a 49% hazard reduction (p<0.0001). Acoramidis also showed that 53 events were avoided per 100 treated participants (95% CI:29–79) at Month 30. These data were presented in a Late Breaking Clinical Trials Oral Presentation at the HFSA Annual Scientific Meeting 2025 and simultaneously published in Journal of the American College of Cardiology (JACC).

•Earlier in the year at the European Society of Cardiology Congress, BridgeBio shared a post-hoc analysis of ATTRibute-CM, demonstrating a significant reduction in risk of CVM through 42 months post-randomization, with a 44% hazard reduction, setting a new standard for CVM outcomes for patients with ATTR-CM. Acoramidis also demonstrated a significant 46% hazard reduction in the risk of the composite outcome of CVM or first CVH through 42 months.

•More data on Attruby will be shared at the American Heart Association (AHA) Congress in November 2025 and in medical congresses throughout 2026.

BBP-418 – Glycosylation substrate for limb-girdle muscular dystrophy type 2I/R9 (LGMD2I/R9):

•FORTIFY, the Phase 3 clinical trial of BBP-418, successfully achieved all primary and secondary endpoints of its interim analysis.

•Findings included a highly statistically significant increase of 1.8x change from baseline (p<0.0001) of glycosylated alpha-dystroglycan (αDG) observed in the BBP-418 group compared to approximately no change in the placebo group from baseline to 3 months, which was sustained at 12 months (p<0.0001).

•An average reduction in serum creatine kinase (CK), a marker of muscle breakdown, of 82% change from baseline (p<0.0001) was observed in BBP-418 treated individuals.

•Importantly, statistically significant and clinically meaningful improvements in ambulation [100-meter timed test (100MTT) velocity, p<0.0001] and pulmonary function [forced vital capacity (FVC) % predicted, sitting position, p=0.0071] were also observed at 12 months in the BBP-418 group compared with the placebo group.

•BBP-418 was well-tolerated with no new or unexpected safety findings observed.

•BridgeBio intends to file a New Drug Application (NDA) for approval with the FDA in the first half of 2026.

•If successful, BBP-418 could be the first approved therapy for individuals living with LGMD2I/R9, potentially representing the first approval of a therapy for any form of LGMD.

•The Company intends to initiate clinical studies of BBP-418 in LGMD2I/R9 for individuals less than 12 years of age and in LGMD2M/2U in the near future.

Encaleret – Calcium-sensing receptor (CaSR) antagonist for autosomal dominant hypocalcemia type 1 (ADH1) and chronic hypoparathyroidism:

•CALIBRATE, the Phase 3 clinical trial of oral encaleret in ADH1, a genetic form of hypoparathyroidism, successfully achieved all pre-specified primary and key secondary efficacy endpoints.

•The primary endpoint was met with 76% of participants administered encaleret achieving both serum and urine calcium within the respective target ranges at Week 24 compared to 4% when on conventional therapy at Week 4 (p<0.0001).

•In a key secondary analysis, 91% of participants administered encaleret achieved intact parathyroid hormone above the lower limit of the reference range at Week 24 compared to 7% of participants when on conventional therapy at Week 4 (p<0.0001).

•Encaleret was well-tolerated with no discontinuations related to study drug.

•BridgeBio intends to submit a NDA to the FDA in the first half of 2026, and a Marketing Authorization Application to the European Medicines Agency to follow.

•If approved, encaleret would be the first therapy indicated for individuals living with ADH1.

•The Company plans to initiate a registrational clinical trial of encaleret in pediatric ADH1 in the first quarter of 2026

•The Company also plans to initiate a Phase 3 study of encaleret in chronic hypoparathyroidism in 2026.

Infigratinib – FGFR1-3 inhibitor for achondroplasia and hypochondroplasia:

•PROPEL 3, the Phase 3 clinical trial of infigratinib in achondroplasia, the most common form of disproportionate short stature, is fully enrolled with 114 participants randomized.

•BridgeBio expects topline results of PROPEL 3 in early 2026.

•BridgeBio has reached regulatory alignment with the FDA on the clinical development plan for infigratinib in infants and toddlers with achondroplasia from birth to less than 3 years old. Based on the discussion, the Company initiated clinical development in this important age range.

•The first participant in the Phase 2 portion of ACCEL 2/3 in hypochondroplasia was dosed in April 2025 and the Company expects to fully enroll the Phase 2 portion of the study by the end of 2025. The Phase 2 data is expected in the second half of 2026.

•Infigratinib demonstrates single-digit nanomolar potency in vitro across causative FGFR3 variants in hypochondroplasia, consistent with its activity in achondroplasia, highlighting robust preclinical efficacy across FGFR3-driven skeletal dysplasias (Demuynck et al., JBMR, 2025).

•In achondroplasia, infigratinib has received Breakthrough Designation from the FDA, Orphan Drug Designation, Fast Track Designation, and Rare Pediatric Disease Designation. To date, in hypochondroplasia, infigratinib has received Fast Track Designation and Orphan Drug Designation from the FDA and EMA.

•If successful, infigratinib would be the first approved oral therapy option for children living with achondroplasia and hypochondroplasia.

Cash, cash equivalents and marketable securities totaled $645.9 million as of September 30, 2025, compared to cash and cash equivalents of $681.1 million as of December 31, 2024.

The $35.2 million decrease is primarily attributable to net cash used in operating activities of $389.5 million for the nine months ended September 30, 2025, the repayment of the Company’s previous term loan under its credit facility (including prepayment fees) of $459.0 million in February 2025, and the repurchase of common stock of $48.3 million using proceeds from the 2031 Notes in February 2025. These outflows were partially offset by net proceeds of $563.0 million from the issuance of the 2031 Notes in February 2025 and net proceeds of $297.0 million from the execution of the Royalty Interest Purchase and Sale Agreement with HealthCare Royalty, a related party, and Blue Owl Capital in June 2025.

Total revenues, net for the three months ended September 30, 2025, were $120.7 million compared to $2.7 million for the same period in the prior year. The $118.0 million increase was primarily driven by a $108.1 million increase in net product revenue from the Company's commercial product, Attruby, a $5.6 million increase in license and services revenue, and a $4.3 million increase in royalty revenue earned on net product sales of BEYONTTRA in the EU and Japan.

Total revenues, net for the nine months ended September 30, 2025, were $347.9 million compared to $216.0 million for the same period in the prior year. The $131.9 million increase was primarily driven by a $216.4 million increase in net product revenue from the Company's commercial product, Attruby, and a $6.1 million increase in royalty revenue earned on net product sales of BEYONTTRA in the EU and Japan. These increases were partially offset by a $90.6 million decrease in license and services revenue, reflecting the timing of recognition of upfront payments from the Company's exclusive license agreements with collaboration partners as well as regulatory-related milestones recognized upon the approval of BEYONTTRA in the EU and pricing approval in Japan.

Operating costs and expenses for the three months ended September 30, 2025 were $265.9 million compared to $194.5 million for the same period in the prior year. The $71.4 million increase was primarily driven by a $68.8 million increase in selling, general and administrative (“SG&A”) expenses largely reflecting the Company’s investments in support of the commercial launch and ongoing activities of Attruby, and a $6.0 million increase in total cost of revenues, primarily due to the cost of Attruby products sold.

These increases were partially offset by a $7.6 million decrease in research and development ("R&D") expenses as a result of the Company's reprioritization of its R&D programs.

Operating costs and expenses for the nine months ended September 30, 2025 were $731.7 million compared to $583.0 million for the same period in the prior year. The $148.7 million increase was primarily driven by a $179.0 million increase in SG&A largely reflecting the Company’s investments to support the commercial launch and ongoing activities of Attruby, and an $11.1 million increase in total cost of revenues, primarily due to the cost of Attruby products sold. The increases were partially offset by a $40.6 million decrease in R&D expenses as a result of the Company's reprioritization of its R&D programs.

Stock-based compensation expenses included in operating costs and expenses for the three months ended September 30, 2025 were $35.3 million, of which $21.9 million is included in SG&A expenses, $12.3 million is included in R&D expenses, $0.7 million is included in restructuring impairment and related charges, and $0.4 million is included in cost of goods sold. Stock-based compensation expenses included in operating costs and expenses for the same period in 2024 were $27.1 million, of which $15.0 million was included in SG&A expenses and $12.1 million was included in R&D expenses.

Stock-based compensation expenses included in operating costs and expenses for the nine months ended September 30, 2025 were $102.0 million, of which $63.1 million is included in SG&A expenses, $37.5 million is included in R&D expenses, $0.8 million is included in restructuring impairment and related charges, and $0.6 million is included in cost of goods sold. Stock-based compensation expenses included in operating costs and expenses for the same period in the prior year were $77.4 million, of which $47.5 million was included in SG&A expenses and $29.8 million was included in R&D expenses, and $0.1 million was included in restructuring, impairment and related charges.

Total other income (expense), net for the three and nine months ended September 30, 2025, was $(41.3) million and $(153.9) million, respectively, compared to $27.5 million and $91.0 million, respectively, for the same periods in the prior year.

The change in total other income (expense), net of $68.8 million for the three months ended September 30, 2025, compared to 2024 was primarily due to a decrease in gain on deconsolidation of subsidiaries of $52.0 million, and an increase in noncash interest expense on deferred royalty obligations of $36.4 million, partially offset by a decrease in interest expense of $11.3 million, and an increase in other income of $7.8 million related to noncash income from the Company's equity method investment.

The change in total other income (expense), net of $244.9 million for the nine months ended September 30, 2025, compared to 2024 was primarily due to a decrease in gain on deconsolidation of subsidiaries of $178.3 million, an increase in noncash interest expense on deferred royalty obligations of $86.5 million, and an increase in net loss from equity method investments of $37.1 million; partially offset by a decrease in interest expense of $28.0 million, an increase in other income of $11.1 million for the change in fair value of the embedded derivative liability component of the Company's deferred royalty obligation, an increase in other income of $7.5 million for services provided under the transition service agreements, and an increase in other income of $7.8 million related to noncash income from the Company's equity method investment.

For the three and nine months ended September 30, 2025, the Company recorded a net loss attributable to common stockholders of BridgeBio of $182.7 million and $532.1 million, respectively, compared to $162.0 million and $270.7 million, respectively, for the same periods in the prior year.

For the three and nine months ended September 30, 2025, the Company reported a net loss per share of $0.95 and $2.79, respectively, compared to $0.86 and $1.46, respectively, for the same periods in the prior year.
