GeneDx Reports Fourth Quarter and Full Year 2025 Financial Results and Reaffirms Guidance for Full Year 2026

GeneDx Holdings Corp. (Nasdaq: WGS), the leader in rare disease diagnosis and improving health through the power of genomic data, today reported its financial results for the fourth quarter and full year of 2025.

“The unmet need for early, accurate genomic diagnosis is enormous, and families are waiting far too long for answers. GeneDx is uniquely positioned to deliver for patients, clinicians, and partners - and our results demonstrate that. Our team is executing at the highest level, our platform continues to scale, and GeneDx InfinityTM gives us a compounding data advantage that strengthens with every test we run,” said Katherine Stueland, President and CEO of GeneDx. “The business has never been in a better position for continued growth and success. As we enter 2026, we will layer new growth drivers onto an already powerful foundation - expanding into large, underpenetrated markets where patients are waiting for a diagnosis that GeneDx can provide today.”

Business Highlights

Strategic Expansion & Market Leadership

• Launched GeneDx Infinity™: Unveiled the world’s largest and most diverse rare disease dataset – including over 1 million exomes and genomes, more than 2.5 million genetic tests, and over 8 million phenotypic data points – that fuels the #1 genetic test.
• Expanded into general pediatrics: Unlocked GeneDx’s largest addressable opportunity to bring genomic testing to the front line of care for more families.
  • Commended the American Academy of Pediatrics for issuing updated guidance in June 2025, now recommending exome and genome sequencing as first-tier tests for children with global developmental delay or intellectual disability.
• Expanded into prenatal diagnostics: Announced GenomeDx Prenatal™, a phenotype-informed, trio-based whole genome sequencing test for pregnancies with fetal anomalies identified via ultrasound, enabling clinicians and expecting families to access actionable genomic insights during one of the most critical moments in pregnancy care.
• Launched ultraRapid genome sequencing: Offered accelerated, comprehensive and actionable genomic insights for neonatal and pediatric patients in the NICU and PICU in as soon as 48 hours.
• Expanded payer coverage: Secured Medicaid coverage for exome and genome sequencing in 8 new states (including CA, CO, OH), bringing the total states covering exome or genome sequencing in the pediatric outpatient setting to 38 and the total states covering rapid genome sequencing in the neonatal intensive care unit (NICU) to 17.
• Strengthened leadership: Positioned the company for the next phase of growth and scale to help more families with the power of our data, AI-driven technology, and clinical expertise.
• Named to the 2026 TIME100 Health List: This recognition comes during Rare Disease Month and underscores the growing global acknowledgment of rare disease as a public health priority, as well as the critical role of genomics in accelerating diagnosis, advancing discovery, and improving outcomes for patients and families worldwide.

Innovation & Clinical Leadership

• Granted FDA Breakthrough Device designation: Received designation for GeneDx ExomeDx™ and GenomeDx™ associated with causes of life-threatening diseases or genetic disorders to aid in diagnosis of symptomatic patients, underscoring GeneDx’s leadership in genomic medicine and critical role in delivering fast, accurate answers for patients with rare diseases.
• Acquired Fabric Genomics: Expanded delivery of genomic insights globally by enabling decentralized interpretation powered GeneDx InfinityTM.
• Advanced genomic newborn screening (gNBS): Extended leadership in genomic newborn screening through participation in key programs, including:
  • Announced participation in the nation’s first multi-state genomic newborn screening initiative, BEACONS (Building Evidence and Collaboration for GenOmics in Nationwide Newborn Screening), which launched with a $14.4 million award from the National Institutes of Health (NIH) to enroll up to 30,000 newborns in as many as 10 states over the next three years.
  • Announced a partnership with Florida’s Sunshine Genetics Network, the nation’s first state-backed genomic newborn screening program, to offer whole genome sequencing for newborns at select academic medical centers and hospitals.
  • Sequenced more than 22,000 newborns through the GUARDIAN (Genomic Uniform-screening Against Rare Disease In All Newborns) study, which was recognized as part of JAMA’s annual Research of the Year Roundup.

Non-GAAP Financial Measures

GeneDx believes non-GAAP measures are useful in evaluating its operating performance. GeneDx uses this supplemental information to evaluate its ongoing operations and for internal planning and forecasting purposes. GeneDx believes that non-GAAP financial information, when taken collectively with its GAAP financial information, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Reconciliations of non-GAAP financial measures to the most directly comparable financial results as determined in accordance with GAAP are included at the end of this press release following the accompanying financial data. We define non-GAAP financial measures as GAAP measures, excluding certain items such as stock-based compensation expense, depreciation and amortization, restructuring costs, changes in the fair value of financial liabilities, and other expenses that the Company believes are not indicative of its ongoing operations. A reconciliation of non-GAAP guidance measures to corresponding GAAP measures is not available on a forward-looking basis without unreasonable effort due to the uncertainty of expenses that may be incurred in the future. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures and not rely on any single financial measure to evaluate our business.
