GAITHERSBURG, Md., January 12, 2026 — 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 2025.

“In 2025, GeneDx continued its journey of transforming the standard of pediatric care by accelerating the use of genomics to the earliest moment families need answers. In doing so, we delivered on our commitment to high growth and profitability, thanks to the relentless commitment of our team,” said Katherine Stueland, President and CEO of GeneDx. “As we enter 2026, GeneDx is accelerating. Powered by GeneDx Infinity – the world’s largest rare disease genomic dataset – and our AI‑driven platform, we are positioned for durable, profitable growth over the next several years while accelerating diagnoses for patients around the world. We are expanding – scaling across care settings, growing internationally, deepening partnerships across the healthcare ecosystem, and investing in the data and expertise that will define the next era of precision medicine – to make earlier diagnosis the norm, not the exception. Our growth is purposeful, and it is inseparable from our impact.”

Ms. Stueland will present at the 44th Annual J.P. Morgan Healthcare Conference on January 14th in San Francisco, CA. A live and archived webcast of the event and the accompanying presentation will be available on the “Events” section of the GeneDx investor relations website at https://ir.genedx.com/.

“We delivered on our commitment to drive more than 30% growth for the year with volume growth rates accelerating each quarter. Accessioning more than 30,000 patients in the fourth quarter, we are demonstrating the power and momentum of our data, scale advantage, and commercial strength to drive sustained high growth and an attractive gross margin profile,” said Kevin Feeley, CFO of GeneDx. “As we look to 2026, we are operating from a position of financial strength, allowing us to invest in our commercial engine and innovation pipeline to open new markets and fuel high growth – expected to be 33% to 35% in 2026 – and an industry-leading business well into the future.”

Preliminary Full Year and Fourth Quarter 2025 Financial Results (Unaudited)

Management expects GeneDx to report:

Revenues

•Revenues of approximately $427 million for full year 2025, an increase of 41% year-over-year (previously raised guidance was $425 to $428 million)

•Revenues of approximately $121 million in the fourth quarter 2025, an increase of 27% year-over-year

•Exome and genome revenues of approximately $360 million for full year 2025, an increase of 54% year-over-year (58% excluding a one-time 2024 benefit) (previously raised guidance was 53% to 55%)

•Exome and genome revenues of approximately $104 million in the fourth quarter 2025, an increase of 32% year-over-year (43% excluding a one-time 2024 benefit)

Exome and genome volume

•Exome and genome test result volume of 97,271 for full year 2025, an increase of 30.5% year-over-year (guidance was at least 30% growth)

•Exome and genome test result volume of 27,761 in the fourth quarter, an increase of 34.3% year-over-year

Gross Margin

•Full year 2025 GAAP and adjusted gross margin of approximately 70% and 71%, respectively (previously raised guidance was adjusted gross margin of 70% to 71%)

•Fourth quarter GAAP and adjusted gross margin of approximately 70% and 71%, respectively, compared to adjusted gross margin of 70% in the fourth quarter of 2024

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

Cash, cash equivalents, marketable securities and restricted cash of approximately $172 million as of December 31, 2025.

GeneDx Full Year 2026 Guidance

For full year 2026 management expects GeneDx to deliver:

Metric Guidance
Revenue $540 to $555 million
Growth in exome and genome revenue 33% to 35%
Growth in exome and genome volume 33% to 35%
Adjusted gross margin At least 70%
Adjusted net income Positive

GeneDx has not completed the preparation of its consolidated financial statements for the year ended December 31, 2025. The preliminary, unaudited results presented in this press release for the quarter and year ended December 31, 2025 are based on current expectations and are subject to adjustment, as the company completes the preparation of its 2025 year-end consolidated financial statements and its 2025 year-end audit. Adjusted gross margin and adjusted net income are non-GAAP financial measures. The Company is not able to reconcile the expected preliminary guided non-GAAP measures to the most directly comparable GAAP financial measures without unreasonable effort because it is unable to predict, forecast or determine the probable significance of various reconciling items with a reasonable degree of accuracy.

GeneDx will release financial results for the fourth quarter and full year of 2025 before the market opens on Monday, February 23, 2026. On the same day, management will host a conference call to discuss financial and operating results at 8:30 a.m. Eastern Time. Investors interested in listening to the conference call are required to register online. A live and archived webcast of the event will be available on the “Events” section of the GeneDx investor relations website at https://ir.genedx.com/.

Business Highlights

Strategic Expansion & Market Leadership

The preliminary, unaudited results presented herein for the quarter and year ended December 31, 2025, are approximates based on current expectations and subject to adjustment as the company completes the preparation of its 2025 year- end consolidated financial statements and its 2025 year-end audit. 2 Adjusted gross margin and adjusted net income are non-GAAP financial measures. Revenue and adjusted gross margin growth rates in the comparative 2024 period exclude revenue and costs of sales from the exited Legacy Sema4 diagnostic testing business. The Company is not able to reconcile the expected preliminary guided non-GAAP measures to the most directly comparable GAAP financial measures without unreasonable effort because it is unable to predict, forecast or determine the probable significance of various reconciling items with a reasonable degree of accuracy.
