Third Quarter and Recent Accomplishments and Highlights
Dermatology
•DecisionDx-Melanoma: In October 2023, the Company announced a new study demonstrating DecisionDx-Melanoma outperforms a nomogram developed at the Memorial Sloan Kettering Cancer
Center in predicting the risk of sentinel lymph node positivity in patients with cutaneous melanoma. The study can be found here.
•DecisionDx-SCC: In October 2023, the Company shared new data demonstrating the ability of its DecisionDx-SCC test to identify localized high-risk cutaneous squamous cell carcinoma patients at a higher risk of metastasis who may benefit from adjuvant radiation therapy. See the Company’s news release from October 3, 2023, for more information.
Gastroenterology
•In October, the Company announced new data demonstrating the significant clinical utility of its TissueCypher Barrett’s Esophagus test in guiding risk-aligned upstaging of care for patients with non-dysplastic Barrett’s esophagus (BE) at a higher risk of progression to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) than indicated by their clinicopathologic risk factors. See the Company’s news release from October 2, 2023, for more information.
•In September, the Company announced the publication of data demonstrating that the TissueCypher Barrett’s Esophagus test outperformed standard of care pathology review in predicting malignant progression to HGD and EAC in BE patients with an initial diagnosis of low-grade dysplasia (LGD).The study can be found here.
•In September, the Company announced new data demonstrating its TissueCypher Barrett’s Esophagus test can identify patients at a higher or lower risk of developing esophageal cancer than indicated by pathologic diagnoses and clinical risk factors to guide escalated or de-escalated patient management. See the Company’s news release from September 8, 2023, for more information.
•In August, the Company announced a new study published in The American Journal of Gastroenterology showing how use of TissueCypher Barrett’s Esophagus test results can significantly improve management decisions for BE patients with LGD to improve health outcomes. The study can be found here.
Mental Health
•In September, the Company announced data from a study showing the addition of drug-drug interactions and lifestyle factors to drug-gene interactions provided by its IDgenetix test significantly impacted the number of drug recommendations and contributed to improved remission rates for patients with moderate to severe depression. See the Company’s new release from September 9, 2023, for more information.
Corporate
•In September, the Company announced that it had earned a Top Workplaces National Industry Award, ranking third among 84 Top Workplaces in the healthcare industry.

Use of Non-GAAP Financial Measures (UNAUDITED)
In this release, we use the metrics of Adjusted Revenues, Adjusted Gross Margin and Adjusted EBITDA, which are non-GAAP financial measures and are not calculated in accordance with generally accepted accounting principles in the United States (GAAP). Adjusted Revenues and Adjusted Gross Margin reflect adjustments to GAAP net revenues to exclude net positive and/or net negative revenue adjustments recorded in the current period associated with changes in estimated variable consideration related to test reports delivered in previous periods. Adjusted Gross Margin further excludes acquisition-related intangible asset amortization. Adjusted EBITDA excludes from net loss interest income, interest expense, income tax expense (benefit), depreciation and amortization expense, stock-based compensation expense, change in fair value of contingent consideration and acquisition related transaction costs.
We use Adjusted Revenues, Adjusted Gross Margin and Adjusted EBITDA internally because we believe these metrics provide useful supplemental information in assessing our revenue and operating performance reported in accordance with GAAP, respectively. We believe that Adjusted Revenues, when used in conjunction with our test report volume information, facilitates investors’ analysis of our current-period revenue performance and average selling price performance by excluding the effects of revenue adjustments related to test reports delivered in prior periods, since these adjustments may not be indicative of the current or future performance of our business. We believe that providing Adjusted Revenues may also help facilitate comparisons to our historical periods. Adjusted Gross Margin is calculated using Adjusted Revenues and therefore excludes the impact of revenue adjustments related to test reports delivered in prior periods, which we believe is useful to investors as described above. We further exclude acquisition-related intangible asset amortization in the calculation of Adjusted Gross Margin. We believe that excluding acquisition-related intangible asset amortization may facilitate gross margin comparisons to historical periods and may be useful in assessing current-period performance without regard to the historical accounting valuations of intangible assets, which are applicable only to tests we acquired rather than internally developed. We believe Adjusted EBITDA may enhance an evaluation of our operating performance because it excludes the impact of prior decisions made about capital investment, financing, investing and certain expenses we believe are not indicative of our ongoing performance. 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 loss reported in accordance with GAAP; should be considered in conjunction with our financial information presented in accordance with GAAP; have no standardized meaning prescribed by GAAP; are unaudited; and are not prepared under any comprehensive set of accounting rules or principles. In addition, from time to time in the future, there may be other items that we may exclude for purposes of these non-GAAP financial measures, and we may in the future cease to exclude items that we have historically excluded for purposes of these non-GAAP financial measures. Likewise, we may determine to modify the nature of adjustments to arrive at these non-GAAP financial measures. Because of the non-standardized definitions of non-GAAP financial measures, the non-GAAP financial measure as used by us in this press release and the accompanying reconciliation tables have limits in their usefulness to investors and may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies. 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 tables at the end of this release.
