GeneDx Announces Preliminary 2024 Financial Results

Expects to exceed guidance with full year 2024 revenues1 of at least $299 million

Expects fourth quarter 2024 revenues1 of at least $92 million

Expects to exceed guidance with full year 2024 adjusted gross margin1 of at least 64%

Expects fourth quarter 2024 adjusted gross margin1 of at least 68%

STAMFORD, Conn., January 13, 2025 — GeneDx Holdings Corp. (Nasdaq: WGS), a leader in delivering improved health outcomes through genomic insights, today reported preliminary financial results for the fourth quarter and full year of 2024.

“2024 was a transformative year for GeneDx, as we achieved our profitability milestone of adjusted net income, released landmark studies, strengthened our products and expanded our team to set up for the opportunity ahead,” said Katherine Stueland, CEO of GeneDx. “The economic burden of rare disease is estimated to be $1 trillion annually, with the absence of early diagnosis being a major contributor to this cost and the cause for unnecessary and avoidable suffering faced by too many families. With our differentiated capabilities, GeneDx is setting the standard for the use of genetics in healthcare. We ended 2024 with momentum and are only beginning to unlock our full potential.”

“Our Q4 performance reflects strong execution as we expect to deliver a second consecutive quarter of adjusted net income and our first quarter of positive operational cash flow,” said Kevin Feeley, CFO of GeneDx.

Preliminary Full Year and Fourth Quarter 2024 Financial Results (Unaudited)

Management expects GeneDx to report:

Revenues1

•Revenues1 of at least $299 million for full year 2024, an increase of 54% year-over-year (previous guidance was $284-$290 million).

•Revenues1 of at least $92 million in the fourth quarter 2024, an increase of 59% year-over-year and 20% sequentially.

•Exome and genome test revenues of at least $75.8 million in the fourth quarter 2024, an increase of 93% year-over-year and 26% sequentially.

Gross Margin1

•Adjusted gross margin of at least 64% for full year 2024 (previous guidance was at least 62%).

•Adjusted gross margin of at least 68% for the fourth quarter 2024, up from 64% in the third quarter of 2024.

Full year and fourth quarter 2024 revenues and adjusted gross margin includes $6.8 million of discrete benefit in connection with a multi-year appeal recovery from a single third-party payer. The fourth quarter benefit is composed of $5.8 million to exome genome revenues and $1.0 million to other test lines.

Exome and genome volume

•Exome and genome test result volume of 20,676 in the fourth quarter, an increase of 32% year-over-year and 7% sequentially with exome and genome representing 38% of all tests result volume in the fourth quarter.

1. Revenue and adjusted gross margin results from continuing operations, which excludes any revenue from the exited Legacy Sema4 diagnostic testing business. Total Company Revenue for the full year and fourth quarter 2024 are expected to be at least $302 million and $92 million, respectively.

GeneDx has not completed the preparation of its consolidated financial statements for the year ended December 31, 2024.

9 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 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

10 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. >750K 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.

11 Our data is unmatched in size, breadth, and depth— making it highly infeasible for competitors to recreate • Enriched for rare disease Diagnosing even the rarest conditions for 25 years • 60% of our exomes/genomes are parent/child trios Enabling de novo findings, sequencing asymptomatic parents • 6 million phenotypic datapoints Bridging clinical information and genomic insights • 10+ years of Medicaid patients tested Representing the full US population diversity • All underpinned by expert annotation and curation Bringing answers to more patients today—without future reanalysis

13 Outpatient market expansion: Fueling growth with new indications, coverage and guidelines Today, GeneDx primarily targets epilepsy, autism and intellectual disability/developmental delay, congenital anomalies, and rare disease • We have 80% market share among genetics experts, 12% among pediatric neurologists, and the rest is untapped A disciplined approach to expand into additional indications starting with hearing loss, cerebral palsy and eventually adult disorders including various neurological, cardiology and other domains Expect expanded clinical guidelines and reimbursement coverage over time • American Academy of Pediatrics (AAP) last updated their genetic testing guidelines in 2014 • Contracted with ~80% of commercially-insured lives • Medicaid coverage continues to expand

15 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. 15

16 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.

17 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.

18 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-Bur t C, Kay DM, et al.
