Fourth Quarter and Recent Accomplishments and Highlights
Dermatology - Skin Cancer
- The Company announced the publication of an independent expert consensus paper titled “31-Gene Expression Profiling for Cutaneous Melanoma: An Expert Consensus Panel,” which endorsed the Company’s DecisionDx-Melanoma test. Authored by a panel of ten melanoma experts from leading academic and clinical institutions, the paper presented evidence-based recommendations supporting DecisionDx-Melanoma as a best-practice tool for guiding management decisions in patients with cutaneous melanoma (CM). The panel concluded that the test provides prognostic information independent of traditional clinicopathologic factors and can be integrated with existing staging systems to improve patient risk assessment and help optimize clinical decision-making. Drawing on a comprehensive review of 26 published studies encompassing more than 7,500 patients, the panel used a modified Delphi process to reach unanimous agreement on nine consensus statements defining the test’s role in risk stratification, sentinel lymph node biopsy (SLNB) decision making and long-term patient management. See the Company’s news release from Dec. 9, 2025, for more information.
- The Company also announced new data demonstrating the clinical value of its DecisionDx-Melanoma test in improving SLNB decision making and enhancing recurrence risk prediction in patients with CM. The data was featured in two oral presentations at the 2nd European Congress on Dermato-Oncology. By combining the biologic information of a patient’s tumor with traditional staging, DecisionDx-Melanoma is designed to enhance five-year prognostic accuracy in SLN-negative patients and potentially provide additional clarity for identifying those at higher risk of recurrence. These findings support the test’s potential to help clinicians make more risk-aligned therapeutic decisions and tailor follow-up care according to a patient’s individual risk. See the Company’s news release from Nov. 14, 2025, for more information.
Gastroenterology
- The Company announced the publication of a new systematic review and meta-analysis (SRMA) demonstrating that the TissueCypher Barrett’s Esophagus test provides clinically validated risk stratification for patients with Barrett’s esophagus (BE). The findings confirm that TissueCypher can outperform traditional pathology or clinical factors alone to identify patients at increased risk of developing esophageal cancer. The paper, titled “The Tissue Systems Pathology Test Predicts Risk of Progression in Patients With Barrett’s Esophagus: Systematic Review and Meta-Analysis,” was published in the Journal of Clinical Gastroenterology. The analysis consolidated data from six previously published studies and found that TissueCypher consistently identifies patients at greater risk of progression to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC), a key step toward enabling personalized, risk-aligned patient management aimed at preventing cancer. See the Company’s news release from Dec. 12, 2025, for more information.
Dermatology - Atopic Dermatitis
- The Company announced the limited access launch of AdvanceAD-Tx, a 487-gene expression profile test designed to guide systemic treatment decision making in patients
ages 12 and older with moderate-to-severe atopic dermatitis, following a presentation of the prospective, multicenter development and validation study at the 25 Annual Fall Clinical Dermatology Conference (news release), which was recently published in the Journal of the American Academy of Dermatology (JAAD) (news release). AdvanceAD-Tx is designed to identify patients with a Janus kinase inhibitor (JAKi) responder profile who are more likely to achieve an Eczema Area and Severity Index improvement of 90% (EASI-90), more quickly and with reduced flares and itch by three months, when treated with a JAKi compared to a T helper type 2 (Th2)-targeted therapy. See the Company’s news release from Nov. 11, 2025, for more information from Nov. 11, 2025, for more information.
Uveal Melanoma
- The Company announced new data from the largest prospective, multicenter study to date comparing next-generation sequencing (NGS)-based gene mutation analysis with the combination of DecisionDx-UM and Preferentially Expressed Antigen in Melanoma (PRAME) gene expression for predicting outcomes in patients with uveal melanoma (UM). The study, titled “Early Genetic Evolution of Driver Mutations in Uveal Melanoma,” was conducted by the Collaborative Ocular Oncology Group (COOG) and recently published in Nature Communications. See the Company’s news release from Dec. 17, 2025, for more information.
Corporate
- The Company announced that it was recognized by the Houston Chronicle as a Houston Top Workplace, which celebrates people-focused, standout workplace cultures. This marked the fifth consecutive year the Company had been ranked among the Houston metro area’s esteemed workplaces. Castle also earned three Culture Excellence awards in the areas of Employee Appreciation, Employee Well-Being and Professional Development. See the Company’s news release from Nov. 17, 2025, for more information.

Use of Non-GAAP Financial Measures (UNAUDITED)
In this release, we use the metrics of Adjusted Revenues, Adjusted Gross Margin, Adjusted EBITDA and Adjusted Net (Loss) Income per Share, Basic and Diluted, 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) income: interest income, interest expense, income tax benefit or expense, depreciation and amortization expense, stock-based compensation expense and change in fair value of equity securities. Adjusted Net (Loss)
Income per Share, Basic and Diluted, excludes a one-time adjustment of an acceleration of amortization expense for our IDgenetix test from net (loss) income.
We use Adjusted Revenues, Adjusted Gross Margin, Adjusted EBITDA and Adjusted Net (Loss) Income per Share, Basic and Diluted, 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. Adjusted Net (Loss) Income per Share, Basic and Diluted, is calculated by excluding a one-time adjustment of an acceleration of amortization expense for our IDgenetix test from net loss. We believe that providing Adjusted (Loss) Net Income per Share, Basic and Diluted, may also help facilitate comparisons to our historical periods. 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, net (loss) income or net (loss) income per share 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.
