How to read SGML (cyclical commodity producer)
A miner or energy producer earns whatever the commodity price is, so a single DCF swings with the cycle. Judge it against peers and where you think the commodity cycle is heading.

Standard DCF doesn't fit SGML well — but that's expected for this kind of business. The EV/Sales Peer Comparison below uses the metrics actually used by analysts who value metal mining. Reverse DCF + Football Field also work as cross-checks.
Miners, metals and energy producers earn whatever the commodity price is at the time. A discounted-cash-flow model leans on recent cash flow, so it swings with the cycle: the result is dominated by where we are in the commodity cycle rather than by durable business economics.
For this business type, lean on the EV/Sales peer comparison and Reverse-DCF below (how today's price compares to similar producers and what growth it implies), and weigh the commodity-price outlook. Treat the DCF number as a rough mid-cycle reference, not a buy/sell trigger.
How does SGML stack up against its closest peers?
We take the 8 same-industry companies most similar to SGML (similar size) and check what investors are paying for each dollar of their revenue (or profits). If SGML is much more expensive on the same yardstick, that's a red flag — unless you have a specific reason it deserves a premium. For a leveraged business, FCF yield (in the table) is usually more reliable than EV/Sales, because revenue multiples ignore differences in margins and debt.
▾ What's "EV / Sales" in plain English?
EV (Enterprise Value) = market cap + total debt − cash. It's "what you'd pay to buy the entire company outright" — you pay the market cap to shareholders and take over their debt, but you keep their cash. EV is fairer than market cap alone because it includes the debt the new owner inherits.
EV / Sales = EV ÷ annual revenue. So "2.5×" means investors pay $2.50 of enterprise value per $1 of yearly sales. Higher = market is paying more per dollar of sales (usually because they expect future growth or fat margins).
p25 / median / p75 are the 25th, 50th (middle), and 75th percentile of the peers' multiples. Half the peers fall between p25 and p75. The median (p50) is the typical peer — that's the benchmark we compare to.
Bold middle number = median peer. Half the peers trade above it, half below. Computed over 8 same-industry peers; implausible multiples excluded.
⚠️ Important caveat: peer multiples only work if the peers are genuinely comparable. Always check the peer list below — if the auto-picker grabbed micro-caps or unrelated businesses, the comparison is noise. A medical-device giant priced against tiny biotech startups won't produce a useful signal.

Quality & solvency checks
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
Why it matters: Cheap-looking stocks (low P/E or P/B) often have low Z-scores because the market knows the company is dying. Z-score warns you before you fall into a value trap.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
The Z-score needs working capital, retained earnings, EBIT, sales and total assets from the latest balance sheet, and at least one of those isn't reported in machine-readable form here — common for foreign private issuers. We leave it blank rather than compute a distress verdict from an estimated input. It doesn't affect the reported figures in the financial tables below.
Why it matters: High score = fundamentals improving. Low score = deteriorating. Especially powerful for filtering cheap stocks: cheap + high F-score historically outperforms; cheap + low F-score is often a value trap.
Reference: 7–9 = strong · 4–6 = mediocre · 0–3 = weak
Full explanation →
The F-score compares two consecutive years of income, cash-flow and balance-sheet data. We have 3 years of income data for this filer, but no machine-readable cash-flow statement — so several of the nine checks have no input at all. We show nothing rather than score a partial year against itself. The reported figures in the financial tables below are unaffected.
A standard discounted cash flowDCF — Discounted Cash Flow — sums up all future cash a business will produce, adjusted for the fact that future dollars are worth less than dollars today.
Why it matters: It is the most fundamentally honest valuation method when applicable — but only works for companies with predictable, positive cash flow.
Reference: Best for: mature, profitable businesses. Fails for: pre-profit growth, banks, REITs.
Full explanation → (DCF) valuation is not meaningful for Sigma Lithium Corp because its free cash flowFree Cash Flow (FCF) — Operating cash flow minus capital spending: cash left after a company covers operating costs, taxes and interest and reinvests in the business — but BEFORE repaying debt principal or paying dividends.

Full explanation → is negative and it has not been consistently profitable, as indicated by its 'Net income NEGATIVE latest' health signal. Investors are likely betting on the future production and demand for lithium, which is not fully captured in backward-looking models. The market may be assigning value to the potential for significant resource extraction and future supply contracts, which is not in the model. The #1 quantifiable risk is the company's inability to achieve consistent profitability.

Anatomy of a share
What you're buying per share. Bars are at the same scale so you can see the relative size of revenue, costs, cash flow, and debt — not just read them in a table.
What's free cash flow / what do these mean?
Revenue per share — how much the business earns from customers, divided by the number of shares outstanding. Top of the income statement.
Earnings per share — profit left after operating costs, interest, and taxes, per share. Two versions appear on this page and are not interchangeable: GAAP diluted EPS uses the company's weighted-average diluted share count during the reporting period (this is the "earnings" in "price-to-earnings"); net income per current share divides annual net income by today's share count. They differ whenever the share count has changed.
Owner-earnings free cash flow per share — the cash the business produces for shareholders. Savng's owner-earnings FCF subtracts capital expenditures and stock-based compensation from operating cash flow (SBC is a real dilution cost even though it's non-cash). This is deliberately more conservative than "standard" FCF, which subtracts only capital expenditures — so our figure is lower than the headline FCF you'll see elsewhere. FCF funds dividends, buybacks, debt repayment, and acquisitions; a company can report positive earnings yet negative FCF.
Debt per share — total interest-bearing borrowings divided by shares. High debt-per-share next to thin FCF-per-share is a fragility signal.
What you actually need to decide
Every stock price is a disagreement. Here's the single thing that must go right for the bulls, the single thing that breaks the thesis, and the concrete signposts to watch so you can update your view as real results arrive.
Why it matters: A company can show big profits on paper while burning through cash. FCF is what actually fills the bank account.
Reference: Healthy mature businesses convert 8–15% of revenue into FCF · Growth companies often negative
Full explanation →, as indicated by 'FCF negative', implies ongoing reliance on external financing and potential dilution if profitability is not achieved.
- Quarterly production volume and sales figures
- Achieving positive operating cash flow
- Updates on new off-take agreements
The trend, in plain numbers (FY2024 → FY2025, latest reported)
Straight from the financial statements — no model, no opinion. For a small or unprofitable company, the direction of these numbers usually tells you more than any single valuation.
- Still unprofitable at -$50.2M — loss narrowing.
Nothing was clearly worsening year-over-year.

Growth / Revenue DCF
No cash flow statement data available - using revenue/margin growth model as fallback.
Show advanced inputs
| Revenue Growth | 15.0% |
What this model does NOT do: this is a consolidated owner-earnings FCF model. Standalone segment assumptions: none. It does not project production volumes, realized commodity prices and unit cash costs independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates. The calculator above can only approximate a segment's impact through the single consolidated growth rate — it cannot model any one line separately. For a true segment-level view, build a separate model from the company's segment disclosures.

These are timing signals, not value signals — they describe the stock's recent price behavior, not what the business is worth. Use them for the "the thesis looks good, but is now the moment?" question. Each tile below explains what it's saying.
Why it matters: Short-term contrarian indicator. Extreme readings often precede mean reversion, though not always.

Why it matters: When the fast line crosses above the slow line, short-term momentum is turning up; below, turning down. A timing cue, not a value signal.
Reference: Line above signal = bullish momentum · below = bearish

Technicals describe price, not the business. A great company can have a "bearish" tape (a buying chance) and a weak one a "bullish" tape (a trap). Pair these with the valuation and health sections above.

- FCF negative: revenue/margin growth model projects future cash flows from revenue trajectory.
- INVARIANT: weighted IV is non-positive. Model may not be appropriate.
- Model implies no positive equity value under these assumptions. Valuation is speculative/low-confidence.
- Illiquidity discount 7% applied (small/micro-cap — harder to exit, demand a margin).
