GeneDx to host conference call today at 8:30 a.m. ET

GAITHERSBURG, Md., April 30, 2025 — GeneDx Holdings Corp. (Nasdaq: WGS), a leader in delivering improved health outcomes through genomic insights, today reported its financial results for the first quarter of 2025.
“Healthcare is at an inflection point where integrating genomic insights into standard care is becoming essential – both for better clinical outcomes and for saving the healthcare system valuable dollars,” said Katherine Stueland, CEO of GeneDx. “The first quarter exceeded our expectations across all measures, headlined by 62% revenue growth in exome/genome and our third consecutive quarter of profitability, demonstrating the leverage in our business model to drive sustained, profitable growth. We are well positioned to transform access to genomic testing globally, driving improved outcomes on an even larger scale.”
“Our business continued to exceed expectations, with volume growth accelerating throughout the quarter,” said Kevin Feeley, CFO of GeneDx. “Looking forward, the combination of continued core momentum, the rolling expansion of new indications in the outpatient setting, and the recent launch of a new ultraRapid genome product are expected to drive incremental volume growth opportunities throughout the remainder of 2025 and beyond.”

Total GAAP gross margin was 67%.

Operating expenses
Adjusted total operating expenses were $52.3 million, or 60% of revenues in the first quarter of 2025, compared to 74% in the first quarter of 2024
Total GAAP operating expenses were $63.0 million.



Net Income
Adjusted net income was $7.7 million compared to an adjusted net loss of $8.0 million in the first quarter of 2024
GAAP net loss was $6.5 million.
Cash position
Cash, cash equivalents, marketable securities and restricted cash was $160.2 million as of March 31, 2025.
Cash flow for the first quarter 2025 included:
$4.1 million in cash generated from ordinary operations; and
$13.9 million in proceeds, net of fees, from the issuance of 150,000 shares of Class A common stock in connection with sales pursuant to our “at-the-market” offering.

1Adjusted gross margin, adjusted total operating expenses and adjusted net income/(loss) are non-GAAP financial measures. See appendix for a reconciliation of GAAP to Non-GAAP figures presented.

GeneDx Full Year 2025 Guidance
GeneDx has updated its full year 2025 guidance. Management expects GeneDx to deliver:
Revenues between $360 to $375 million for full year 2025, inclusive of $3 to $5 million in post-close revenue contribution from the planned acquisition of Fabric Genomics, assuming a second quarter 2025 close (previous guidance was revenues between $350 to $360 million);
Growth in exome/genome volume and revenue of at least 30% (unchanged);
Adjusted gross margins between 66%-68% (previous guidance was between 65%-67%); and
Profitability with adjusted net income each quarter and for full year 2025 (unchanged).

First Quarter 2025 Business Highlights
Driving sustainable growth and market leadership
Announced plans to acquire Fabric Genomics, which will accelerate GeneDx’s entry into a supplemental market of genomic medicine: decentralized testing with centralized intelligence.
Announced ultraRapid Whole Genome Sequencing, offering accelerated, comprehensive and actionable genomic insights for neonatal and pediatric patients in the NICU and PICU in as soon as 48 hours.
Launched Epic Aura, which seamlessly integrates GeneDx exome and genome testing into the native ordering and resulting workflows of many of the largest health systems across the country.
Expanded commercial footprint for exome and genome testing with cerebral palsy (CP) as a new indication, underscoring the importance of improving access to exome and genome testing for patients with CP to shorten the diagnostic odyssey and accelerate the path to treatment.
Expanded commercial footprint for exome and genome testing with Inborn Errors of Immunity (IEIs) as a new indication, empowering ordering clinicians with more accurate and comprehensive genetic insights to better treat this patient population.
Accelerated adoption of exome and genome sequencing coverage by state Medicaid programs, bringing the total states covering exome or genome sequencing in the pediatric outpatient setting to 33 (New Mexico announced April 2025) and the total states covering rapid genome sequencing in the neonatal intensive care unit (NICU) to 14.
Recognized by Fast Company as one of the world’s most innovative companies, honoring GeneDx’s innovative approach to accelerating genetic diagnosis and transforming the future of healthcare by ending the diagnostic odyssey.

Advancing the field to accelerate market expansion

Published data from the Seqfirst-neo study, a pioneering study conducted in partnership with Seattle Children’s and the University of Washington, revealing that widespread use of rapid genome sequencing (rGS) demonstrates that at least 60% of level IV NICU infants should be receiving rGS.
Seqfirst-neo is the first study to use exclusion, rather than inclusion, criteria for which infants should receive genomic testing in the NICU, setting a new standard of care by enabling neonatologists to more easily identify patients to receive testing, and expanding access to patients who previously would not have been offered testing.
42% of diagnosed infants would have been missed using conventional NICU protocols (69% of whom were non-white), highlighting the limitations of current diagnostic approaches and the correlated inequity of care.



Showcased key research and innovation at the 2025 American College of Medical Genetics (ACMG) Annual Meeting that demonstrated:
The relative impact of RNAseq across a large cohort of clinically diverse patients receiving exome-based testing for rare diseases was low, and for most patients the key factors in clinically impactful VUS resolution are providing detailed and accurate clinical information, trio-based testing, and selecting a laboratory with an extensive clinical and genomic database.
Parental needs during whole genome sequencing (WGS) are multifaceted and interconnected, with parents’ informational, emotional, and logistical needs all suggesting the importance of ongoing, empathetic engagement with healthcare providers. Parental feedback also highlighted the need for peer support from families either similar genetic or clinical diagnoses or those similarly navigating the WGS process, emphasizing the role of patient advocacy in the diagnostic and treatment journey for children with developmental disorders.
The results of the first 10,000 participants enrolled in the GUARDIAN study demonstrate the feasibility of screening for a targeted set of genes in a diverse newborn population with genomic newborn screening (gNBS). 74.0% of parents consented for their newborn to participate, highlighting the wide acceptance of more advanced and modernized newborn screening with gNBS.
Announced Multiscore, an advanced AI-powered decision support tool designed to revolutionize genetic analysis by improving diagnostic efficiency, streamlining workflows, and enhancing clinical insights.
Through the combination of GeneDx’s industry leading proprietary dataset, publicly available data, and the power of AI, Multiscore enables faster, more accurate identification of genetic conditions, providing a scalable solution for clinical interpretation embedded directly within GeneDx’s platform, and reducing the time required for manual review by analysts, ultimately shortening the overall turnaround time for delivering results.

22 GeneDx has spent over a decade solving for the limitations of the past and we're working to change the perception of exome and genome sequencing Then Now Results take months Tests are prohibitively expensive GeneDx’s tests are accessible and widely covered by insurance Results are confusing, filled with useless information Patients receive fewer variants of uncertain significance and more definitive answers Turnaround time Cost Interpretation Nothing to do or change based on the results Results unlock a growing number of approved therapies, clinical trials, dietary and behavioral health therapies GeneDx delivers results in hours, days or weeks Other testing (CT scan, MRI, gene panels) offers the same information Exome and genome uncover what other tests don’t, which saves time & money Actionability Value


 
23 Accelerating and deepening our competitive advantage with every patient Pay it forward data strategy: the snowballing effect of data accumulated with ever patient we test drives our underlying interpretation platform to get smarter, faster, and more scalable That’s enable us to identify more than 400 new disease-gene relationships—and counting. >800K exomes & genomes Patent applications have been filed to develop an IP portfolio directed to our innovative platform of genetic variant identification, clinical interpretation and innovative diagnostic tools developed using artificial intelligence.

30 Genetic evidence is one of the most powerful tools to improve the therapeutic development process Today Tomorrow The average therapeutic development cycle: Including genetic evidence can dramatically reduce cost, shorten timelines, and improve success rates: o Up to 60% of this cost is spent in the clinical phase. Costs $2.6B o Inefficient trials—driven by patient identification and recruitment challenges—extend timelines. Takes 12 years o Most trials fail due to safety and efficacy concerns. Fails 90% of the time Genetic evidence can reduce development costs by up to 25%. Leveraging genetic data can cut development timelines by up to 5 years. Drugs with supporting genetic evidence are 2.6 times more likely to succeed. 30


 
31 Our partnerships with biopharma companies help accelerate treatments— from early discovery through commercialization Our collaborations are impacting the lives of patients today: Akouos (Eli Lilly) Regeneron GeneDx partnered with Akouos to match patients with the clinical trial that enabled Aissam Dam to hear for the first time. Through a data partnership with GeneDx, Regeneron received valuable insights into the landscape of hearing loss patients and their associated variants. After receiving treatment, Aissam said: “There’s no sound I don’t like. They're all good.” Opal heard her mother's voice for the first time after participating in Regeneron's clinical trial.


 
32 Every year, thousands of newborns with actionable conditions are missed by traditional newborn screening (NBS). Federal NBS guidelines recommend testing for 37 conditions with biomarkers—measurable changes in the baby’s blood that indicate the baby may have a disorder. However, there are hundreds of actionable conditions that lack biomarkers. We believe in a future where every newborn’s genome is sequenced at birth Genomic sequencing can detect conditions without biomarkers, expanding the number of conditions screened to ~450. By supplementing traditional NBS with genomic sequencing, we can offer crucial information to improve health outcomes.


 
33 GeneDx is the leader set to revolutionize the standard approach to today's newborn screening, enabling diagnoses before symptoms even start Screened 17,000 healthy infants with genome sequencing, toward goal of >100,000 3.2% true positive rate, and 92% of true positives would not have been detected with today's standard newborn screening Early diagnosis for conditions like long QT syndrome and Wilson disease not included in standard newborn screening, resulted in life-saving treatments Without this screening, the average age of diagnosis for these conditions is 7-11 years old​ Results from the GUARDIAN study, published in Journal of the American Medical Association, set the foundation for clinically-actionable, ethical and responsible gNBS More than 70% of parents consented to gNBS, with 90% of those opting for inclusion of optional neurodevelopmental disorders GeneDx has screened more newborns than any other commercial laboratory. This experience gives GeneDx a deep understanding of how to offer this testing at scale. References: 1. Ziegler A, Koval-Burt C, Kay DM, et al.
