Castle Biosciences, Inc. (CSTL) - Porter's Five Forces: Competitive rivalry

You're looking at the competitive landscape for Castle Biosciences, Inc. (CSTL) right now, and the rivalry is definitely heating up in the specialized diagnostics space. It's not a simple price war; it's a battle for clinical relevance. The competition is intense with established genomic diagnostics firms like Veracyte and Guardant Health. To be fair, Guardant Health, for example, is projecting full-year 2025 revenue between $850 million and $860 million, with oncology revenue expected to grow approximately 15% year over year for 2025. That scale presents a significant contrast to Castle Biosciences' raised 2025 guidance of $327 million to $335 million.

The core of the fight isn't just about who has the best technology; it's about getting that technology embedded in physician practice, which means securing favorable reimbursement and clinical utility data. Competition is based on clinical evidence, not just price; tests must be included in guidelines. This is where Castle Biosciences is putting its chips down, as evidenced by the strong adoption of its core offerings.

Here's a quick look at how Castle Biosciences stacks up against two of its major rivals on a few key metrics as of late 2025:

You see that Castle Biosciences' core tests-DecisionDx-Melanoma and TissueCypher-saw 36% combined volume growth in Q3 2025. That's real momentum. Specifically, DecisionDx-Melanoma delivered 10,459 reports, up 12% year-over-year, and TissueCypher hit 10,609 reports, a surge of 75% year-over-year. Still, the pressure from reimbursement challenges is real; for instance, DecisionDx-SCC revenue was only about $15 million in Q2 2025 due to Novitas and MolDx LCD (Local Coverage Determination) changes.

The competitive field is broad, too. Companies like Exact Sciences compete in the broader cancer diagnostics space, which means Castle Biosciences must maintain its niche focus. The rivalry focuses on securing favorable reimbursement and clinical utility data. The company's cash position of $287.5 million as of September 30, 2025, provides a buffer to fund the necessary clinical studies and payer negotiations. However, the new AdvanceAD-Tx test faces a reimbursement climb from ground zero, with revenue expected to be immaterial in 2026.

The competitive intensity is also visible in the product pipeline focus:

• DecisionDx-Melanoma volume growth expected to be high single-digit for full-year 2025.
• TissueCypher test reports in Q3 2025 reached 10,609, up 75% year-over-year.
• Total test reports for all products in Q3 2025 were 26,841.
• AdvanceAD-Tx, targeting a $33 billion market opportunity, had a limited clinical launch in November 2025.
• DecisionDx-SCC test reports for the nine months ended September 30, 2025, were 13,323.

Castle Biosciences, Inc. (CSTL) - Porter's Five Forces: Threat of substitutes

You're looking at the competitive landscape for Castle Biosciences, Inc. (CSTL) tests, and the threat of substitutes is definitely a major factor you need to model. This force isn't just about direct product replacement; it's about established clinical inertia and alternative pathways that avoid invasive procedures altogether.

High Threat from Traditional, Established Diagnostic Methods like Sentinel Lymph Node Biopsy (SLNB)

The established standard of care, particularly for melanoma staging, presents a significant hurdle. The American Society of Clinical Oncology (ASCO) released new guidelines in 2025 that actively promote de-escalation of axillary surgery. This directly challenges the need for procedures like the sentinel lymph node biopsy (SLNB) when a prognostic test could guide the decision.

Here's what the ASCO 2025 guidelines suggest regarding SLNB:

• For select low-risk, postmenopausal women ($\geq 50$ years) with small ($\leq 2$ cm), HR+/HER2- tumors, SLNB may be omitted if the ultrasound is negative.
• Trials supporting this omission, like SOUND and INSEMA, showed axillary recurrence rates as low as 1-1.7% when SLNB was skipped in these specific patient groups.
• Avoiding SLNB reduces complications like lymphedema, which is a major quality-of-life factor for patients.

Castle Biosciences, Inc. (CSTL) has positioned its DecisionDx-Melanoma test to help clinicians avoid SLNB in low-risk patients, but the guidelines themselves create a non-test-based substitution pathway. Still, the company is pushing for its test to be used to inform surveillance and therapy initiation, noting that DecisionDx-Melanoma was associated with a 32% reduction in mortality risk compared to untested patients in a real-world cohort of over 13,500 patients. That's a powerful counter-argument to simply skipping staging.

Substitutes Include Other Prognostic Tests and Traditional Pathology Reports

The threat isn't just procedural avoidance; it's also about other tests that might be perceived as sufficient or are already embedded in clinical workflows. Traditional pathology reports, like the Brigham & Women's Hospital (BWH) staging for squamous cell carcinoma (SCC), serve as a baseline substitute. Castle Biosciences, Inc. (CSTL)'s DecisionDx-SCC test is designed to enhance prognostic accuracy beyond these traditional methods. For instance, integrating DecisionDx-SCC significantly refined metastatic risk prediction in patients classified as High-Risk or Very High-Risk by National Comprehensive Cancer Network (NCCN) guidelines ($\text{p} < 0.001$).

However, reimbursement challenges highlight the substitution inertia. Despite the clinical data, the Novitas Local Coverage Determination (LCD), effective April 24, 2025, signified noncoverage for DecisionDx-SCC. Even with this payer headwind, the test still generated 13,323 reports in the first nine months of 2025, suggesting strong clinician belief in its value, but this volume is under pressure compared to the 14,026 IDgenetix reports delivered in the same period in 2024 before its discontinuation in May 2025. The company's core revenue drivers, DecisionDx-Melanoma and TissueCypher, achieved 33% combined growth in Q2 2025, which helps offset risks in other areas.

Here is a quick look at how Castle Biosciences, Inc. (CSTL)'s core tests stand against substitution pressures as of late 2025:

New, Non-Invasive Liquid Biopsy Technologies are Emerging as Future Substitutes

The most direct future threat comes from other non-invasive molecular tests, especially liquid biopsies, which bypass tissue sampling entirely. For Castle Biosciences, Inc. (CSTL)'s DecisionDx-UM test, which is the current standard of care for uveal melanoma (UM), a new non-invasive technology is already in development that could substitute it. Researchers presented data on a novel 17-biomarker test for UM that uses a liquid biopsy of the anterior chamber of the eye. This emerging technology demonstrated the ability to distinguish low- and high-risk lesions with a sensitivity of 91% and a specificity of 50% in an independent validation. If this test achieves broader clinical adoption and reimbursement, it poses a direct threat to the tissue-based DecisionDx-UM.

Clinical Guidelines Must Endorse the Test to Overcome Substitution Inertia

You see this clearly with the DecisionDx-SCC situation. Despite strong data showing it enhances NCCN risk stratification ($\text{p} < 0.001$), the lack of endorsement via favorable Medicare coverage from Novitas has created a massive substitution headwind, forcing reliance on clinician conviction alone. Conversely, DecisionDx-Melanoma's value is reinforced by its inclusion in risk stratification discussions, and the fact that DecisionDx-UM is already identified as a prognostic factor in the American Joint Committee on Cancer (AJCC) Staging Manual (v7 and v8) shows the power of guideline inclusion. For Castle Biosciences, Inc. (CSTL) to maintain or grow market share against procedural alternatives and new molecular tests, securing official endorsement in major clinical guidelines is not just helpful; it's defintely crucial for overcoming physician inertia.

Castle Biosciences, Inc. (CSTL) - Porter's Five Forces: Threat of new entrants

The threat of new entrants for Castle Biosciences, Inc. is structurally low, primarily because the barriers to entry in the specialized molecular diagnostics space are exceptionally high. You can't just launch a new test; you have to build a fortress of clinical evidence and regulatory compliance first.

• - Low threat due to extremely high regulatory and clinical barriers.
• - Significant capital is required; Castle Biosciences had \$275.9 million in cash as of June 30, 2025.
• - Need for extensive clinical validation and peer-reviewed data to gain physician trust.
• - Long, complex process to secure widespread payer reimbursement is a major barrier.
• - FDA Breakthrough Device designation for DecisionDx-Melanoma creates a temporary competitive advantage.

To challenge Castle Biosciences, Inc., a new competitor must overcome the established scientific credibility. For instance, the DecisionDx-Melanoma test is supported by more than 50 peer-reviewed publications and has been studied in more than 10,000 patient samples. This level of validation is not built overnight.

The financial and regulatory hurdles alone act as significant deterrents. Here's the quick math on the scale of investment and time required to even attempt market entry:

Furthermore, securing payment is a battle in itself. The reimbursement landscape for molecular diagnostics is adversarial, with payors often requiring extensive documentation of medical necessity. It can take up to six months to resolve claims, and demonstrating clinical and economic utility is integral to securing coverage. This complexity forces potential entrants to staff large revenue cycle management functions just to chase payments.

The FDA's decision to grant Breakthrough Device designation to Castle Biosciences, Inc.'s DecisionDx-Melanoma test provides a clear, albeit temporary, moat. This designation signals regulatory recognition of the test's potential to offer more effective diagnosis or treatment, which immediately raises the bar for any new competitor trying to prove superiority in the melanoma space.
