Is Ero Copper Corp. (ERO) a good stock to buy?
What we have tested leans negative. To like it anyway you need a reason our checks do not capture.
What each rating means, in numbers
How wild is the price? — Wild. The share price swings about 54% in a typical year, which puts it in the above average. Out of every 100 companies that swung like this, about 3.7 went bankrupt within the year. Across the three periods we tested that ran from 0.9% to 5.7%.
What "tested" means here, and why there is no score out of 100
Tested means the read was measured against what actually happened afterwards, on a history that keeps the companies that were later delisted, using only figures that had been filed on the day they are used. Survival was ranked on companies that really did fail. What an owner keeps was tested across the universe from 2011 to 2025.
The full record of everything we have tested is on the research pages.
Which benchmark. Over the period we tested, the median listed company returned +5.8% a year while the S&P 500 returned about +13.9% — the index is weighted by size and was carried by a handful of enormous winners. So "beats the index" and "beats the other companies you could have bought" are different questions. Where a read says it picks better companies, it means the second one. None of these gets you an index fund's return, and we would rather say that than imply otherwise.
The quality read is the strongest thing we have tested: 131,000 company-quarters across 5,300 companies, where the weakest scorers went on to fail at 5.4% against 1.4% for the strongest, holding in every era and all twelve sectors. It still says less likely to break, not likely to beat the market — every band in that study lost to the index at the median, because the median listed company does.
Each read is shown on its own rather than merged into a single score, so you can see which part is strong and which is weak instead of taking an average on trust.

📍 Where to start on this page, and what to look at first
How to read ERO (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.
-
1
EV/Sales peer comparison ↓
How the price compares to similar producers is more meaningful than a through-cycle DCF.
-
2
Interactive calculator (test cycle assumptions) ↓
Flex the growth/discount inputs to see how sensitive the value is to where we are in the cycle.
Standard DCF doesn't fit ERO 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 ERO stack up against its closest peers?
We take the 8 same-industry companies most similar to ERO (similar size) and check what investors are paying for each dollar of their revenue (or profits). If ERO 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, EV/EBIT and FCF yield (both in the table) are 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 5 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 Ero Copper Corp. because the model projects no positive equity value and the company has negative 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. The cash actually available to investors.
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 the 'FCF negative' flag. Investors are likely betting on future production growth and commodity price appreciation, which are not fully captured by backward-looking cash flow models. The market may be assigning value to the potential for new resource discoveries or expansions of existing mines, which are not in the model. The number one quantifiable risk is the inherent volatility of copper prices.

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 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.
