Safe harbor statement

This presentation contains forward-looking statements under the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts contained in this presentation, including statements regarding our market opportunity, our proposed products and launch schedules, our reimbursement coverage and our product costs, our commercial partners and potential acquisitions, our user experience, our clinical trials and studies, our financial performance, our strategies, our anticipated revenue and financial outlook, our goals and general business and market conditions, are forward-looking statements.

These forward-looking statements are subject to known and unknown risks and uncertainties that may cause actual results to differ materially, including: we face numerous uncertainties and challenges in achieving our financial projections and goals; we may be unable to maintain our business and operations as planned due to disruptions and economic uncertainty caused by the COVID-19 pandemic; we may be unable to further increase the use and adoption of Panorama and Horizon through our direct sales efforts or through our laboratory partners; we may be unable to develop and successfully commercialize new products, including Signatera and Prospera; we have incurred losses since our inception and we anticipate that we will continue to incur losses for the foreseeable future; our quarterly results may fluctuate from period to period; our estimates of market opportunity and forecasts of market growth may prove to be inaccurate; we may be unable to compete successfully with existing or future products or services offered by our competitors; we may engage in acquisitions, dispositions or other strategic transactions that may not achieve our anticipated benefits and could otherwise disrupt our business, cause dilution to our stockholders or reduce our financial resources; we may need to raise additional capital to support our business plans, which may not be available when necessary or on favorable terms; we may not be successful in commercializing our cloud-based distribution model; our products may not perform as expected; the results of our clinical studies, including our SNP-based Microdeletion and Aneuploidy RegisTry, or SMART, Study, may not be compelling to professional societies or payors as supporting the use of our tests, particularly in the average-risk pregnancy population or for microdeletions screening, or may not be able to be replicated in later studies required for regulatory approvals or clearances; if either of our primary CLIA-certified laboratory facilities becomes inoperable, we will be unable to perform our tests and our business will be harmed; we rely on a limited number of suppliers or, in some cases, single suppliers, for some of our laboratory instruments and materials and may not be able to find replacements or immediately transition to alternative suppliers; if we are unable to successfully scale our operations, our business could suffer; the marketing, sale, and use of Panorama and our other products could result in substantial damages arising from product liability or professional liability claims that exceed our resources; we may be unable to expand, obtain or maintain third-party payer coverage and reimbursement for Panorama, Horizon and our other tests, and we may be required to refund reimbursements already received; third-party payers may withdraw coverage or provide lower levels of reimbursement due to changing policies, billing complexities or other factors, such as the increased focus by third-party payers on requiring that prior authorization be obtained prior to conducting a test; if the FDA were to begin actively regulating our tests, we could incur substantial costs and delays associated with trying to obtain premarket clearance or approval and incur costs associated with complying with post-market controls; litigation or other proceedings, resulting from either third party claims of intellectual property infringement or third party infringement of our technology, is costly, time-consuming and could limit our ability to commercialize our products or services; any inability to effectively protect our proprietary technology could harm our competitive position or our brand; and we cannot guarantee that we will be able to service and comply with our outstanding debt obligations or achieve our expectations regarding the conversion of our outstanding convertible notes. 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 on Forms 10-K and 10-Q and in other filings we make with the SEC from time to time. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this presentation may not occur and our actual results could differ materially and adversely from those anticipated or implied. As a result, you should not place undue reliance on our forward-looking statements. 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.
