Earth Science Tech (ETST): analysis traps
Where its figures could mislead a reader, and what to check before taking them at face value · Data: Q1 FY27, to Jun 30, 2026, filed Aug 7, 2026; rules v1.1
Earth Science Tech (ETST): 1 rule of 10 triggered on the filings to Jun 30, 2026: receivables growing = future cash is certain; 5 with insufficient data; 2 not applicable. Each is a question to verify, with the normal explanation that would produce the same figures.
Check these first
Receivables growing = future cash is certain Triggered · severity high · confidence medium
Receivables grew 148% year over year in Q1 FY27 against revenue growth of 3%, and the quarter before 176% against 9%; days sales outstanding is 6 against a median of 3 over the eight quarters before. More of each quarter's revenue is still owed by customers.
Innocent reading: Seasonality: a quarter that always ends with big shipments.
Every rule
A01 FCF growth = the business improved Not triggered confidence high
Free cash flow did not rise ($4M → $1M): the trap does not arise.
The figures and how they are read
| Fiscal year before | FY25 |
| Fiscal year | FY26 |
| Operating cash flow, year before | $4M |
| Operating cash flow | $2M |
| Capex, year before | $753K |
| Capex | $757K |
| Free cash flow, year before | $4M |
| Free cash flow | $1M |
| Change in FCF | −$2M |
| Change in capex | 3,454 |
| Working capital: change in its cash contribution | −$2M |
FCF = operating cash flow − cash capex; ΔFCF = ΔOCF − ΔCapEx; the working-capital part is the change in the cash-bridge items (receivables, inventory, payables, accruals), with the sign of the cash flow statement
Source: FY26 (cash flow statement, fiscal year) · FY25 (cash flow statement, fiscal year before)
A07 Stock compensation added back = no economic cost Insufficient data
fewer than two fiscal years of stock compensation and share counts on file
B02 Receivables growing = future cash is certain Triggered severity high · confidence medium
Receivables grew 148% year over year in Q1 FY27 against revenue growth of 3%, and the quarter before 176% against 9%; days sales outstanding is 6 against a median of 3 over the eight quarters before. More of each quarter's revenue is still owed by customers.
The figures and how they are read
| Quarter | Q1 FY27 |
| Revenue, year over year | +3.0% |
| Receivables, year over year | +147.6% |
| Quarter before | Q4 FY26 |
| Revenue y/y, quarter before | +9.5% |
| Receivables y/y, quarter before | +175.9% |
| Days sales outstanding | 6.1 |
| DSO, median of eight quarters | 2.8 |
| Receivables | $846K |
| Revenue | $9M |
receivables and revenue against the same quarter a year earlier; DSO = receivables / quarterly revenue × days, against the median of the eight quarters before
Source: Q1 FY27 (receivables and revenue) · Q1 FY26 (the same quarter a year earlier)
What would explain it innocently
- Seasonality: a quarter that always ends with big shipments
- An acquisition brought its own receivables
- New business with longer standard terms (government, large enterprise)
- Currency: receivables booked in a strengthening currency
What to look for in the filing
- The receivables ageing and the allowance for credit losses
- Any factoring or receivables sold (and whether with recourse)
- Credit terms by customer group
What would show the trap does not apply
- Receivables fall back in line with revenue in the next quarter and DSO returns to its history
- The 10-Q attributes the increase to a disclosed one-off (a large customer's timing, an acquisition) and the allowance for doubtful accounts did not rise
Look again: next filing.
B08 Adjusted profit = economic profit Insufficient data
no reconciliation table read from the releases yet and fewer than three quarters with both an adjusted and a GAAP EPS
C02 Low net debt = no refinancing risk Insufficient data
no debt figure could be read from the balance sheet (the filing may tag it in other lines)
D03 EPS growth = profit growth Not triggered confidence high
EPS rose 200% and net income rose 341% in Q3 FY26; the share count fell 3.3%: EPS growth follows profit growth.
The figures and how they are read
| Quarter | Q3 FY26 |
| Quarter before | Q3 FY25 |
| EPS, year before | $0.00 |
| EPS | $0.00 |
| Net income, year before | $206K |
| Net income | $910K |
| Diluted shares, year before | 302.9M shares |
| Diluted shares | 292.8M shares |
| EPS growth | +200.0% |
| Net income growth | +341.1% |
| Diluted shares: change | -3.3% |
| eps from profit | $0.00 |
| eps from share count | $0.00 |
EPS and net income against the same quarter a year earlier; the EPS bridge attributes the change to profit first, then to the share count (the order is fixed and disclosed)
Source: Q3 FY26 (net income, diluted shares, EPS) · Q3 FY25 (the same quarter a year earlier)
E02 Low P/E at a cyclical peak = undervalued Insufficient data
no market value or trailing net income in the valuation research
E07 A precise DCF value = the true value Insufficient data
no DCF in the valuation research for this company
J06 A bank's low P/E and high profit = safe Not applicable
not a bank
J08 A REIT's low net income = the dividend is unsafe Not applicable
not a REIT
What the statuses mean
Triggered: the filings show the pattern; read the normal explanations and the missing evidence before concluding anything. To review: one quarter or a weak signal; a reader's judgement, not a pattern. Not triggered: the pattern is absent on these figures. Insufficient data: the filings read so far do not hold what the rule needs; this is not a clean bill. Not applicable: the rule is not meant for this kind of company (a bank's working capital, a loss-making quarter's EPS growth). Out of date: the latest filing is more than fifteen months old.
Severity is what the pattern could mean for cash, value or solvency; confidence is how reliable the inputs and the reading are. The two are kept apart.

Every rule and the companies it triggers on → Earth Science Tech: cash flow →
Each rule reads the company's own filings by a fixed formula and says what would explain the same figures innocently. A triggered rule is a question to verify, not a finding of manipulation, and not a view on the stock. Missing data is shown as missing, never as clear. Not investment advice.
