CSTL Q1 2025: 75% Adj. Gross Margin Amid SCC Reimbursement Risk
- Acquisition Enhances GI Portfolio: The acquisition of Previse adds a complementary methylation-based assay and non-endoscopic sponge technology to the existing GI offering (TissueCypher), potentially broadening the product pipeline and addressing unmet clinical needs in esophageal disorders.
- Robust Clinical Evidence Driving Adoption: The strong clinical data for Castle's tests, particularly DecisionDx-SCC and DecisionDx-Melanoma, underscores their clinical utility—in reducing unnecessary treatments and improving patient outcomes—which may drive increased test adoption and market share.
- Sales Force Reallocation to Growth Segments: Shifting the sales focus toward high-growth areas, especially melanoma, with additional investments in expanding and optimizing sales territories could accelerate test uptake and revenue growth in key markets.
- Reimbursement uncertainty for DecisionDx-SCC: There is unresolved ambiguity around Medicare reimbursement as the company is pending reconsideration requests, with no clear timeline provided. This could negatively impact future revenue if unfavorable decisions occur.
- Lack of immediate revenue contribution from Previse acquisition: The acquisition of Previse is positioned as a technology and pipeline opportunity with no immediate impact on revenue or EBITDA, potentially posing short-term integration and cash allocation risks.
- Shifting sales focus could hinder SCC growth: With the sales force refocusing heavily on melanoma—leaving SCC promotion less prioritized—the slower SCC volume growth may affect overall revenue diversification, especially given the historical contribution of SCC to cost-savings for Medicare.
| Metric | YoY Change | Reason |
|---|---|---|
Total Revenue | +20.7% (from $72.97M to $88.0M) | Q1 2025 total revenue increased by 20.7%, driven by solid gains across both revenue segments. While dermatologic tests showed modest growth, the surge in non-dermatologic tests—with an 83% jump—boosted overall revenue. This reflects an ongoing trend from prior periods where strong product adoption laid the foundation for continued expansion. |
Dermatologic Tests Revenue | +6.2% (from $59.33M to $63.0M) | Dermatologic revenue grew modestly by approximately 6.2% YoY, continuing the momentum of increased test report volumes from DecisionDx‑SCC and DecisionDx‑Melanoma seen in prior periods. The relatively smaller increase suggests that while the product remains steady, the growth engine shifted largely towards non-dermatologic offerings compared to previous performance. |
Non‑Dermatologic Tests Revenue | +83% (from $13.64M to $25.0M) | Non‑dermatologic revenue surged by 83%, largely due to a dramatic increase in test volumes—especially for the TissueCypher test—and an improved average selling price. In Q1 2025, the jump from a lower base in Q1 2024 reflects an accelerated uptake that builds on previously laid groundwork, marking a notable shift in revenue composition. |
Profitability | Shift from net income of $9,590K (Q4 2024) and operating income of +$4,050K to a net loss of $25,848K and operating loss of –$27,928K in Q1 2025 | Profitability reversed sharply in Q1 2025 due to significant increases in operating expenses. A major factor was a steep rise in amortization of acquired intangible assets (an increase of approximately $26M) coupled with higher SG&A and increased cost of sales. This cost pressure overwhelmed the revenue gains witnessed previously, marking a stark contrast to the streamlined cost profile of Q4 2024. |
Cash Flow | Operating cash flow declined from +$24,365K (Q4 2024) to –$6,036K, resulting in a net cash decline of –$30,020K | Operating cash flow turned negative in Q1 2025, reflecting the impact of higher operating outlays—including increased bonus and healthcare payments—and an overall increase in expenses. Compared to the robust cash generation in Q4 2024, the lower collections relative to heightened costs, along with lower proceeds from financing activities, contributed to the significant net cash decline. |
