Rhea AI CSTL FY2025

Fixed operating costs and rising noncash charges now shape earnings more than revenue growth does.

In FY2025, cash conversion diverged from reported earnings: the company posted a net loss of -$24.2M while producing operating cash flow of $64.3M. That gap coincided with depreciation and amortization rising from $16.0M in FY2024 to $40.8M in FY2025, so cash generation was partly cushioned by noncash expense rather than reflected in bottom-line profit.

Gross margin compressed from 81.9% to 79.4%, while gross profit was nearly flat despite revenue increasing 3.7%; additional volume produced little added gross-dollar contribution. SG&A then rose to $229.3M, helping turn FY2024 operating income of $8.7M into a FY2025 operating loss.

Capital intensity increased: capital expenditures rose from $28.3M in FY2024 to $36.0M in FY2025, reducing operating cash flow of $64.3M to free cash flow of $28.3M. The current ratio also fell from 7.3x to 5.3x, indicating near-term liabilities grew faster than current assets even as leverage remained low.

Profitability
25

Castle Biosciences has an operating margin of -12.4%, meaning the company loses $12 on every $100 of revenue. This results in a profitability score of 25/100. This is down from 2.6% the prior year.

Growth
87

Castle Biosciences's revenue grew a modest 3.7% year-over-year to $344.2M. This slow but positive growth earns a score of 87/100.

Leverage
87

Castle Biosciences carries a low D/E ratio of 0.02, meaning only $0.02 of long-term debt for every $1 of shareholders' equity. This conservative leverage earns a score of 87/100, indicating a strong balance sheet with room for future borrowing.

Liquidity
92

With a current ratio of 5.26, Castle Biosciences holds $5.26 in current assets for every $1 of short-term obligations. This comfortable liquidity earns a score of 92/100.

Cash Flow
48

Castle Biosciences has a free cash flow margin of 8.2%, earning a moderate score of 48/100. The company generates positive cash flow after capital investments, but with room for improvement.

Returns
27

Castle Biosciences posts a -5.1% return on equity (ROE), meaning it loses $5 for every $100 of shareholders' equity. This results in a returns score of 27/100. This is down from 4.0% the prior year.

Altman Z-Score Safe
5.91

Castle Biosciences scores 5.91, well above the 2.99 safe threshold. The score is driven primarily by a large market capitalization ($987.1M) relative to total liabilities ($107.7M). This indicates low bankruptcy risk based on profitability, leverage, and asset efficiency.

Distress-screening estimate for non-financial companies. Not computed for banks or insurers, where the Altman model does not apply.

Piotroski F-Score Weak
3/9

Castle Biosciences passes 3 of 9 financial strength tests. 2 of 4 profitability signals pass, 1 of 3 leverage/liquidity signals pass, neither operating efficiency signal passes.

Earnings Quality Mixed
N/A

Castle Biosciences reported a net loss of $24.2M while generating $64.3M in operating cash flow. Operations generated cash despite the loss, but with no positive earnings behind it, the ratio between the two carries no quality signal.

Interest Coverage At Risk
N/A

Castle Biosciences reported an operating loss of $42.8M against $86K in interest expense. There is no operating profit to cover interest, so interest must be met from cash reserves or from financing rather than from operations.
