Conference call and webcast today at 4:30 p.m. ET
FRIENDSWOOD, Texas, July 30, 2026 /PRNewswire/ -- Castle Biosciences, Inc. (Nasdaq: CSTL), a company improving health through innovative tests that guide patient care, today announced its financial results for the second quarter ended June 30, 2026.
"The Castle Biosciences team delivered another outstanding quarter," said Derek Maetzold, president and chief executive officer of Castle Biosciences. "We believe our strong growth through the first half of 2026 demonstrates the clinical value our tests bring to patient care and the dedication of our talented team to deliver results so that our clinician customers and patients can act with confidence.
"Given this momentum, we are raising our 2026 total revenue guidance to $365-375 million, up from our previous range of $345-355 million. We also now expect to achieve positive Adjusted EBITDA for the third quarter, the fourth quarter and the full year 2026.
"We are also encouraged by an independent study supporting the clinical impact of AdvanceAD-Tx™ in guiding systemic treatment selection. At the Revolutionizing Atopic Dermatitis meeting in June, data from a multi-center study showed only 54.3% of patients receiving baseline systemic therapy were initially on pathway-concordant treatment; however, following testing with our AdvanceAD-Tx test, 97.8% of patients were initiated on molecularly concordant systemic therapy.
I want to thank the entire Castle team for their focus, commitment and disciplined execution, which continue to advance our mission of improving health through innovative tests that guide patient care."

Second Quarter and Recent Accomplishments and Highlights
Dermatology - Skin Cancer
- The Company announced the publication of a prospective, multicenter study in Dermatology and Therapy demonstrating that DecisionDx-Melanoma's integrated sentinel lymph node biopsy test result (i31-SLNB) outperforms the Melanoma Institute Australia (MIA) nomogram in identifying patients at low and high risk of SLN positivity, supporting more informed SLNB decision-making for patients with cutaneous melanoma (CM). This is the second multicenter study showing that the i31-SLNB result outperforms the MIA nomogram in assessing SLN positivity risk. See the Company's news release from June 25, 2026, for more information.
Dermatology - Atopic Dermatitis
- The Company announced that its AdvanceAD-Tx test has received assay approval from the New York State Department of Health (NYSDOH). With this approval, Castle has New York State approval for all tests within its dermatology and ophthalmology portfolios, its TissueCypher test within gastroenterology and its clinical laboratories in Phoenix and Pittsburgh. See the Company's news release from July 14, 2026, for more information.
- The Company announced that its AdvanceAD-Tx test was selected as the winner of the "Genomics Innovation Award" in the 10th annual MedTech Breakthrough Awards program, which recognizes companies driving meaningful progress and improving patient care across the global health and medical technology industry. AdvanceAD-Tx is Castle's clinically validated gene expression profile (GEP) test designed to guide systemic treatment decision making in patients 12 and older with moderate-to-severe atopic dermatitis (AD). This marks the fifth MedTech Breakthrough Award that Castle has earned for its innovative testing solutions. See the Company's news release from May 12, 2026, 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: interest income, interest expense, income tax benefit or expense, depreciation and amortization expense, stock-based compensation expense and net losses (gains) on 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.
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 Net (Loss) 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 or net loss 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.
