Ero Copper Corp.

Price story Before the numbers, the tape. A stock price moves through four repeating seasons: a flat base (stage 1), an advance (2), a top (3), a decline (4). Where the price sits in that cycle frames everything below.

Ero Copper Corp. trades at $25.6, building a base and 5 weeks into that stage. That is −5.8% against its own 200-day average. It sits at 58% of a 52-week range of $14 to $34. On relative strength it is currently behind the S&P 500 on a trailing-13-week view (6 weeks and counting).

Today the stock is building a base — week 5 of stage 1. At $25.6 it trades −5.8% versus its 200-day average and sits at 58% of its 52-week range ($14–$34).

Against the market, two honest reads. Cumulative: over the last 8.8 years the stock moved +540% while the S&P 500 moved +187% — ahead of the index over the full window. Recent form: on a trailing-13-week view the stock is currently behind (6 weeks and counting; last ahead the week of 2026-06-18) — the ribbon below is that same metric, week by week.

What would end the trend, mechanically: two Friday closes in a row below the 200-day line. That is the exit rule — no debates.

→ The trend is one thing; the bill is another. Are you paying up for it? Next: the P/E sits at the 19th percentile of its own range.

Valuation P/E is the price of $1 of annual profit: how many dollars the market pays for each dollar the company earns in a year.

Ero Copper Corp. trades at 9.2× P/E, near the bottom of its own range — cheaper only 19% of the time. Its long-run median P/E is 16.3×, measured across 4.3 years of weekly readings. This places the multiple against the stock’s own record, and says nothing about what the business is worth.

Today's P/E of 9.2× is near the bottom of its own range — cheaper only 19% of the time, against a long-run median of 16.3× measured over 4.3 years of weekly readings. This is a comparison against the stock's own history — not a claim about what it is worth.

The price move, decomposed: over 3y, of the +3.3%/yr price move, ~+48.4%/yr came from earnings growth and ~−45.1 pp from the multiple (compressing). The split is the honest approximate (price return minus earnings growth); it makes the rally itself visible instead of hiding it behind the percentile.

Put together: the multiple is low against its own past, so the story rests on the earnings line underneath it, not the multiple.

→ Cheap or dear rides on the earnings. Are they actually growing? Next: the fundamental stage — where the business sits in its arc, and how growth has compounded.

Stage: Improving Every business sits somewhere on a fundamental arc, and this page names the spot before anything else. The last twelve quarters of revenue, profit and EPS growth — plus the return the business earns on its capital — are read as curves: Deteriorating (the curves are falling), Turning around (a trough has just formed and the last few quarters lift off it), Improving (the climb off the trough is sustained), Consistent (steadily positive with healthy returns), Topping out (still high but decelerating from the peak). When the curves genuinely disagree the read is Mixed; too little history is No read. CAGR (compound annual growth rate) is the smooth yearly pace that turns the starting value into the latest one — the fairest way to compare growth across different time spans. Read the columns together: if the 1-year number towers over the 10-year, recent growth is running hotter than the long-run trend. A dash means that window is not held, or the base year was a loss (where a growth rate is not meaningful).

Ero Copper Corp. reads as improving on its fundamental arc. Improving — profit growth bottomed 6 quarters ago at −128.6% and has held its recovery at +1400.0%, ROCE lifting at 19.3%. The read is built from 12 quarters across 4 curves, on full evidence.

Why it matters: a sustained climb off the trough is the setup this page is built to catch — the question moves to what you pay for it.

→ The stage names the trajectory. Next: the revenue line that produces it, quarter by quarter.

4-Factor Sector Score

58.3/100 — rank 2 of 6 in Copper · 82% evidence confidence

Ero Copper Corp. scores 58.3 out of 100 against the 6 companies it is compared with in Copper, ranking 2. Acceleration candidate, not a confirmed leader: earnings are strong but sector-relative strength is -2.7% and the one-year return is 90.9%. Do not upgrade until sector-relative strength is above zero and another reported period confirms growth.

The four contributions add to the total exactly: 23.8 + 11.9 + 15.9 + 6.7 = 58.3. This is the SAME number shown on the sector comparison — it is computed once, for the whole peer set, and read here.

What would change it: The read weakens if profit growth turns negative or margin improvement reverses while sector-relative strength deteriorates.

Revenue Revenue is the top line: everything the company billed its customers in the period.

Ero Copper Corp. reported $0.3 B of revenue in the Mar 26 quarter, +100.0% year on year. That is the 5th straight quarter of year-on-year growth. Over 4 years it has compounded at 12.7% a year. The last full year, FY25, came in at $0.8 B. The last four reported quarters add to $0.9 B.

FY25 revenue came in at $0.8 B (+68.1% on the year), capping 4 years at 12.7% compound. The latest quarter (Mar 26) printed $0.3 B, +100.0% year on year — the 5th consecutive quarter of year-over-year growth.

Pace check: the last four quarters averaged +87.5% growth against the decade's 12.7% — the current year is running faster than its own long-run rate.

Acceleration check: trailing-twelve-month revenue grew +87.8% over the last 4 quarters against +44.6%/yr over the last 8 — accelerating; TTM profit +1,400.0% vs +123.6%/yr — accelerating.

→ Revenue grew — did margins hold as it scaled? Next: 34.6% this quarter (+3.8 pp YoY).

Operating margin Operating margin is what is left of every $100 of sales after running the business, before interest and tax. It is the cleanest read on pricing power and cost control.

Ero Copper Corp.'s operating margin is 34.6% in the Mar 26 quarter, +3.8 percentage points against the same quarter a year ago. Across 5 fiscal years the operating margin has ranged 23.3% to 55.1%. The current quarter sits inside that band.

Ero Copper Corp.'s operating margin is 34.6% in the Mar 26 quarter, +3.8 percentage points against the same quarter a year ago. Across 5 fiscal years the operating margin has ranged 23.3% to 55.1%. The current quarter sits inside that band.

The latest quarter's operating margin is 34.6%, +3.8 pp against the same quarter a year ago. Across 5 fiscal years the operating margin has ranged 23.3%–55.1%.

Why the margin moved: operating margin went +3.8 pp year on year while gross margin went −3.9 pp — the gain came mostly from the gross line: input costs and pricing.

→ Margins held — did that reach the bottom line? Next: profit +37.5% in the latest quarter.

Net profit Net profit is what survives every cost, interest and tax — the number EPS, dividends and book value all grow from.

Ero Copper Corp. earned $0.1 B of net profit in the Mar 26 quarter, +37.5% year on year. Full-year FY25 profit was $0.3 B. The 4-year compound rate is 7.8%. That is 42.3% of the quarter's revenue. The same quarter a year earlier earned $0.1 B. 3 of the last 12 reported quarters were loss-making.

Mar 26 profit was $0.1 B, +37.5% year on year. On the full year, FY25 printed $0.3 B (null), and the 4-year compound rate is 7.8%.

→ Profit rose — but did the cash follow? Next: 152% of the last 3 years' profit arrived as cash.

Cash flow — the router The P&L says what was earned; the cash-flow statement says what actually arrived. Operating cash flow (CFO) against profit is the cleanest lie detector in the accounts.

Over the last 3 fiscal years 152% of Ero Copper Corp.'s reported profit arrived as operating cash — the cash follows the profit. In FY25 that was $0.4 B of operating cash against $0.3 B of profit. After $0.3 B of capital spending, $0.1 B was left as free cash.

FY25: operating cash of $0.4 B against reported profit of $0.3 B, leaving free cash of $0.1 B after $0.3 B of capital spending. Across the last 3 fiscal years the conversion rate is 152% of profit.

Cash-flow readings here are annual — that is the resolution our series carries, so this section moves once a year.

Why: conversion is measured cleanly, but the working-capital day-counts behind it sit below what we hold — the move is shown without inventing its driver.

Router verdict: the visible cash user is investment — the next section checks what the spending is buying.

→ So follow the cash to where it goes. Next: $1.0 B of building over 3 years.

Where the cash goes Working capital is the cash tied up between paying suppliers and getting paid: debtor days (customers owe), inventory days (stock waits), and the cash conversion cycle (the whole loop, in days of sales).

Ero Copper Corp. does not report the debtor, inventory and payable day-counts a cash cycle is built from, so this section reads the investment side instead. Capital spending ran $1.0 B over the last 3 years. Averaged over those years that is 42.2% of FY25 revenue a year.

Working-capital day-counts are not in our numbers for this stock, so this section reads the investment side — where the cash is being put to work.

On the investment side: capital spending of $1.0 B over the last 3 fiscal years.

The synthesis: the cash is going into capacity, not disappearing into the cycle — the question becomes whether the new capacity earns.

→ Does all this activity actually earn its cost of capital? Next: ROE is 33% and the ROIC − WACC spread is +5.6 pp.

Return on equity Return on equity (ROE) is the profit the business earns on its shareholders’ money. With the full capital-employed split not in our numbers, ROE is the cleanest long ladder we can draw here.

Ero Copper Corp. earns a ROE of 29% in FY25. That is up from a trough of −12% in FY24. Return on invested capital clears the cost of that capital by +5.6 percentage points, so growth here adds value rather than only size. The wiring behind it is 34.2% net margin on 0.41× asset turns.

FY25 ROE is 29%, recovered from a FY24 trough of −12% — the full ladder below shows the fall and the climb, undoctored.

Why the return is what it is — the wiring (FY25): 34.2% net margin × 0.41× asset turns × 2.04× balance-sheet leverage ≈ 28.6% on equity. Margin is doing the heavy lifting; leverage is a meaningful part of the equation.

The capstone test — ROIC − WACC: 16.7% − 11.1% = a +5.6 pp spread. The 11.1% is an estimate of this company's own cost of capital — read the sign and the size of the spread, not the decimals. A spread this wide means every dollar reinvested creates more than a dollar of value — the engine compounds.

→ Returns like these — is the balance sheet borrowing to make them? Next: debt-to-equity is 0.55.

Dividend

Ero Copper Corp. pays no dividend. Across the last 12 reported quarters it has declared no dividend per share, so there is no payout history to chart and no yield to quote. Companies at this stage typically reinvest earnings rather than distribute them, which makes the cash-flow and reinvestment sections the place that cash shows up.

Ero Copper Corp. does not currently pay a dividend. Across the last 12 reported quarters the company has declared no dividend per share, so there is no payout history to chart and no yield to quote. Companies at this stage typically reinvest earnings instead of distributing them.

→ No payout to follow. The cash question becomes what the business does with what it earns instead.

Debt Debt-to-equity says how much of the business is funded by borrowings. Low is the safe corner; the trend matters as much as the level.

Ero Copper Corp. carries total debt of $0.6 B against shareholder equity of $1.1 B as of Mar 26, a debt-to-equity of 0.55. On the annual view that ratio went from 0.18 in FY21 to 0.67 in FY25. Read the returns elsewhere on this page with that leverage in mind.

Mar 26: total debt of $0.6 B against shareholder equity of $1.1 B — a debt-to-equity of 0.55. On the annual view, debt-to-equity went from 0.18 (FY21) to 0.67 (FY25). Read the returns on this page with that leverage in mind.

→ Who owns this, and are they adding or leaving? Next: short interest is 3.5% of the float.

Ownership There is no quarter-by-quarter holder register to read here, so we read the crowd through short interest — the slice of tradable shares currently sold short, positioned for a fall.

3.5% of Ero Copper Corp.'s tradable float is currently sold short — some money is positioned against it. At typical trading volumes those positions would take about 4.0 days to buy back. There is no quarter-by-quarter holder register to read for this filer, so the crowd is read through short interest instead.

The latest reading: 3.5% of the float is sold short, and at typical trading volumes it would take about 4.0 days to buy those positions back. Some money is positioned against it. This is a single point-in-time reading — we do not yet hold its history, so we show no trend chart.

Why it sits there: who is doing the shorting, and why, does not travel with the number — the level is shown without inventing its story.

→ One last check: does the safety math agree? Next: the balance-sheet safety line.

Safety line The Z-score estimates how far a company sits from balance-sheet distress — above roughly 3 is safe, below roughly 1.8 is the danger zone. It was built for manufacturers, so it is not applied to banks and lenders.

Ero Copper Corp.: the Z-score reads 2.92. A Z-score above roughly 3 reads as safe and below roughly 1.8 as the distress zone, so this sits in the grey band between the two. It is a distance-to-distress estimate from the balance sheet, not a forecast of failure.

Why it matters: a Z-score of 2.92 sits in the grey band — neither clearly safe nor clearly distressed.

The safety line in one sentence: the Z-score reads 2.92.
