Presented at European Association of Dermoto Oncology (EADO) conference in Seville, Spain; April 21-23, 2022 ‡Hazard ratio (HR) was computed using the untested patients as referenced for 31-GEP tested cohort. A HR less than 1.0 demonstrates improved survival in 31-GEP tested patients. Diagnosis date 2016 and onward. Data provides direct evidence that patients tested with DecisionDx-Melanoma have better survival rates than untested patients and suggests that testing can aid in risk-aligned treatment plans for improved patient outcomes and survival rates

29 Cutaneous Squamous Cell Carcinoma Is an Emerging Problem in the U.S. • Managing SCC is a significant clinical issue as deaths from SCC are now estimated to exceed those from melanoma • Because cancer treatment plans and their outcomes are guided by risk for metastasis, prognostic accuracy has direct implications on patient management • Traditional staging fails to identify >30% of SCC cases who go on to metastasize, and >75% of SCC cases are over-called by staging • Unlike melanoma, breast and other common cancers, SCC patient care has not been personalized with risk predicting gene expression profile (GEP) tests SEER data release 2019; Mansouri et al.

34 A clinical hurdle for dermatopathology is the accurate diagnosis of difficult-to-diagnose melanocytic neoplasms Unmet Need in Patients with a Difficult-to-Diagnose Pigmented Lesion Of the estimated two million suspicious pigmented lesions biopsied annually in the U.S., approximately 300,000 of those cannot be classified with confidence as either benign tissue or melanoma through traditional histopathology methods These difficult-to-diagnose lesions are commonly sent for second opinions to expert dermatopathologists who have more experience with challenging cases; however, the nature of many lesions remains ambiguous with discordant rates of lesions in this category of 25-43% (Elmore et al. 2017) Diagnostic ambiguity can lead to clinical management uncertainty and overtreatment, leading to unnecessary excisions and increased patient morbidity, and undertreatment, with the potential for missing diagnoses of malignant melanoma The Clinical Problem

50 Use Of Non-GAAP Financial Measures (Unaudited) In this presentation, we use the metrics of Adjusted Revenue, Adjusted Gross Margin and Adjusted Operating Cash Flow, which are non-GAAP financial measures and are not calculated in accordance with generally accepted accounting principles in the United States (GAAP). Adjusted Revenue and Adjusted Gross Margin reflect adjustments to net revenues to exclude changes in variable consideration related to test reports delivered in previous periods. Adjusted Gross Margin further excludes acquisition-related intangible asset amortization. Adjusted Operating Cash Flow excludes the effects of repayments to Medicare of COVID-19 government relief advancements to healthcare providers. We use Adjusted Revenue, Adjusted Gross Margin and Adjusted Operating Cash Flow internally because we believe these metrics provide useful supplemental information in assessing our revenue and cash flow performance reported in accordance with GAAP, respectively. We believe Adjusted Revenue and Adjusted Gross Margin are also useful to investors because they provide additional information on current-period performance by removing the effects of revenue adjustments related to tests delivered in previous periods and, with respect to Adjusted Gross Margin, acquisition-related intangible asset amortization, which we believe may facilitate revenue and gross margin comparisons to historical periods. We believe Adjusted Operating Cash Flow is also useful to investors as a supplement to GAAP measures in the assessment of our cash flow performance by removing the effects of COVID-19 government relief payments, which we believe are not indicative of our ongoing operations. However, these non-GAAP financial measures may be different from non-GAAP financial measures used by other companies, even when the same or similarly titled terms are used to identify such measures, limiting their usefulness for comparative purposes. These non-GAAP financial measures are not meant to be considered in isolation or used as substitutes for net revenues, gross margin or net cash (used in) provided by operating activities reported in accordance with GAAP and should be considered in conjunction with our financial information presented on a GAAP basis and language from our earnings press release. Accordingly, investors should not place undue reliance on non-GAAP financial measures. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are presented in the slides that follow. We are not providing a target for or a reconciliation of Adjusted Gross Margin, the most directly comparable GAAP measure, for 2025 because we are unable to predict certain items contained in the GAAP measure without unreasonable efforts.
51 Reconciliation of Non-GAAP Financial Measures (Unaudited) The table below presents the reconciliation of adjusted revenue and adjusted gross margin, which are non-GAAP financial measures. See previous slide for further information regarding the Company’s use of non-GAAP financial measures.
52 Reconciliation of Non-GAAP Financial Measures (Unaudited) The table below presents the reconciliation of adjusted operating cash flow, which is a non-GAAP financial measure. See slide 47 for further information regarding the Company’s use of non-GAAP financial measures.
