2 Forward Looking Statements This presentation contains "forward-looking statements" within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and the U.S. Private Securities Litigation Reform Act of 1995, including statements regarding our future performance and our market opportunity, including our expected full year 2025 reported revenue, growth in exome and genome revenue and volume, adjusted gross margin and adjusted net income guidance. These forward-looking statements generally are identified by the words "believe," "project," "expect," "anticipate," "estimate," "intend," "strategy," "future," "opportunity," "plan," "may," "should," "will," "would," "will be," "will continue," "will likely result," and similar expressions. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this press release, including but not limited to: (i) our ability to implement business plans, goals and forecasts, and identify and realize additional opportunities, (ii) the risk of downturns and a changing regulatory landscape in the highly competitive healthcare industry, (iii) the size and growth of the market in which we operate, and (iv) our ability to pursue our new strategic direction. The foregoing list of factors is not exhaustive. A further list and description of risks, uncertainties and other matters can be found in the "Risk Factors" section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and our Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2025, June 30, 2025 and September 30, 2025, and other documents filed by us from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and we assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. We do not give any assurance that we will achieve our expectations. We discuss these and other risks and uncertainties in greater detail in the sections entitled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our periodic reports and other filings we make with the SEC from time to time. Given these uncertainties, you should not place undue reliance on the forward-looking statements. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. Except as required by law, we undertake no obligation to update publicly any forward-looking statements for any reason after the date of this presentation to conform these statements to actual results or to changes in our expectations. We file reports, proxy statements, and other information with the SEC. Such reports, proxy statements, and other information concerning us are available www.sec.gov.

15 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

27 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
