FRIENDSWOOD, Texas–(BUSINESS WIRE<\/a>)– \n\u201cCastle delivered an outstanding fourth quarter that rounded out an exceptional 2024, including 51% revenue growth and 36% test report volume growth compared to 2023,\u201d said Derek Maetzold, president and chief executive officer of Castle Biosciences. \u201cI am incredibly proud of our team’s hard work in achieving these results, including achieving our previously provided 2025 revenue guidance range one year ahead of expectations.<\/p>\n \n\u201cWe are extremely pleased with the progress we made across our initiatives in 2024 in the areas of our core growth drivers, including a 17% increase in our dermatologic test reports (DecisionDx\u00ae<\/sup>-Melanoma and DecisionDx\u00ae<\/sup>-SCC combined) and a 130% increase in our TissueCypher\u00ae<\/sup> Barrett\u2019s Esophagus test reports, over 2023. We believe this was driven largely by the clinical value of our tests, strong execution on our commercial strategy and expansion of our clinical evidence base.<\/p>\n \n\u201cBuilding on our momentum and successes, we expect to continue to focus on delivering operational excellence. Further, sound capital allocation remains a priority, including pursuing strategic opportunities, aimed at driving stockholder value in 2025 and beyond.\u201d<\/p>\n Twelve Months Ended December 31, 2024, Financial and Operational Highlights<\/b><\/p>\n Cash, Cash Equivalents and Marketable Investment Securities<\/b><\/p>\n \nAs of December 31, 2024, the Company\u2019s cash, cash equivalents and marketable investment securities totaled $293.1 million.<\/p>\n Fourth Quarter Ended December 31, 2024, Financial and Operational Highlights<\/b><\/p>\n 2025 Outlook<\/b><\/p>\n \nThe Company anticipates generating between $280-295 million in total revenue in 2025.<\/p>\n Fourth Quarter and Recent Accomplishments and Highlights<\/b><\/p>\n Dermatology<\/i><\/b><\/p>\n Gastroenterology<\/i><\/b><\/p>\n Corporate<\/i><\/b><\/p>\n Conference Call and Webcast Details<\/b><\/p>\n \nCastle Biosciences will hold a conference call on Thursday, Feb. 27, 2025, at 4:30 p.m. Eastern time to discuss its fourth quarter and full-year 2024 results and provide a corporate update.<\/p>\n \nA live webcast of the conference call can be accessed here: https:\/\/events.q4inc.com\/attendee\/686536610<\/a> or via the webcast link on the Investor Relations page of the Company\u2019s website, https:\/\/ir.castlebiosciences.com\/overview\/default.aspx<\/a>. Please access the webcast at least 10 minutes before the conference call start time. An archive of the webcast will be available on the Company\u2019s website until March 20, 2025.<\/p>\n \nTo access the live conference call via phone, please dial 833 470 1428 from the United States, or +1 404 975 4839 internationally, at least 10 minutes prior to the start of the call, using the conference ID 944585.<\/p>\n \nThere will be a brief Question & Answer session following management commentary.<\/p>\n Use of Non-GAAP Financial Measures (UNAUDITED)<\/b><\/p>\n \nIn 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 and change in fair value of trading securities.<\/p>\n \nWe 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\u2019 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.<\/p>\n \nThese 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.<\/p>\n About Castle Biosciences<\/b><\/p>\n \nCastle Biosciences (Nasdaq: CSTL) is a leading diagnostics company improving health through innovative tests that guide patient care.
