Approach 1: Southern Copper Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a business might be worth today by projecting its future cash flows and discounting them back to the present using a required rate of return.

For Southern Copper, the model uses a 2 Stage Free Cash Flow to Equity approach based on cash flows reported and projected in US$. The latest twelve month free cash flow is about $3.45b. Analyst estimates and subsequent extrapolations suggest free cash flow projections reaching $4.58b in 2026 and $7.23b by 2030, with further years gradually increasing as modeled by Simply Wall St.

When all projected cash flows for the next decade and beyond are discounted back, the DCF model arrives at an estimated intrinsic value of about $140.17 per share. Compared with the recent share price of $188.25, this implies Southern Copper trades at roughly a 34.3% premium to the modelled fair value, so the stock screens as expensive under this method.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Southern Copper may be overvalued by 34.3%. Discover 58 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Southern Copper Price vs Earnings

P/E is a common way to value profitable companies because it anchors the share price to actual earnings, which are typically more stable than short term revenue or book value. In general, higher growth expectations or lower perceived risk can justify a higher P/E ratio, while slower growth or higher risk tend to line up with a lower, more conservative multiple.

Southern Copper currently trades on a P/E of 35.87x. This sits above the Metals and Mining industry average P/E of 22.78x, and also above the peer group average of 29.88x. As a result, the stock carries a richer earnings multiple than many sector names.

Simply Wall St’s Fair Ratio for Southern Copper is 28.86x. This is a proprietary estimate of what a more “normal” P/E might look like after considering factors such as the company’s earnings growth profile, profit margins, size, industry and key risks. Compared with a simple peer or industry comparison, the Fair Ratio aims to be more tailored to the company’s specific fundamentals. With the actual P/E of 35.87x sitting above the Fair Ratio of 28.86x, the shares currently screen as expensive on this metric.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Southern Copper Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives is a simple framework on Simply Wall St’s Community page where you attach your story about Southern Copper to concrete forecasts for revenue, earnings and margins, connect that to a fair value, and then compare it with the current share price.

A Narrative is your view of what is happening at the company, written out in plain language and backed by numbers. Instead of only seeing that analysts have a consensus fair value of US$153.27 with targets that range from US$65.52 to US$235.00, you can decide which story you find more reasonable and see the implied fair value that follows from it.

For example, one Southern Copper Narrative might lean toward the bullish end and align with a higher fair value near US$233.07 and a richer future P/E of about 37.97x. Another might sit closer to the cautious end with a fair value around US$67.81 and a future P/E of about 12.12x. As new earnings, project updates or copper market news arrive, Simply Wall St automatically refreshes these Narratives so you can quickly see whether your chosen fair value still makes sense against the live market price.

For Southern Copper however we will make it really easy for you with previews of two leading Southern Copper Narratives:

Fair value in this bullish Narrative framework is about US$233.07 per share.

At the last close of US$188.25, this implies the shares trade roughly 19.2% below that Narrative fair value.

Revenue growth assumed in this Narrative is about 13.45% a year.

• Analysts in this camp see major projects like Tia Maria and Los Chancas, along with strong green technology demand, supporting higher copper volumes and sales over time.
• The Narrative leans on a low cost base, higher projected profit margins and consistent free cash flow as support for a richer future P/E multiple.
• It also flags country, project execution and ESG related risks that could disrupt production plans or raise long term capital and operating costs.

Fair value in this more cautious Narrative is about US$153.27 per share.

At the last close of US$188.25, this implies the shares trade roughly 22.8% above that Narrative fair value.

Revenue growth assumed in this Narrative is about 4.58% a year.

• Analysts here still see production growth coming from a more than US$15b project pipeline, including Buenavista zinc and copper projects in Mexico and Peru.
• The Narrative assumes healthy margins supported by low cash costs, but questions whether the current share price already bakes in high copper prices and strong execution.
• It highlights risks from tariffs and U.S. China tensions, rising operating costs, large capital spending plans and local community disruptions that could cap upside from current levels.
