• If you are wondering whether Alcoa’s current share price gives you value for your money, the key question is how that price compares with what the business might reasonably be worth.
• The stock closed at US$62.64, with a 1.8% decline over 7 days and a 14.1% decline over 30 days, set against a 10.8% gain year to date and a 146.3% return over 1 year that may catch your attention.
• Recent coverage has focused on Alcoa’s position within the broader materials sector and how investors are reacting to changing expectations for aluminum demand and supply. This context helps explain why the stock has pulled back in the short term after strong gains over the past year.
• Alcoa currently holds a valuation score of 6/6. The next sections will walk through the traditional valuation methods behind that score and then finish with a more holistic way to think about what the stock might be worth.

Approach 1: Alcoa Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a stock could be worth by projecting its future cash flows and discounting them back to today’s value. In Alcoa’s case, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections.

Alcoa’s latest twelve month free cash flow is about $307.1 million. Analyst and extrapolated estimates suggest free cash flow reaching around $2.3b in 2030, with interim yearly figures between 2026 and 2035 discounted back to present using Simply Wall St’s assumptions. These projected cash flows are all converted into today’s dollars and then summed to produce an estimated intrinsic value per share.

That process results in a DCF fair value estimate of $126.10 per share. Compared with the recent share price of $62.64, the model implies the stock is trading at a 50.3% discount to this intrinsic value, which indicates that the shares appear undervalued according to this measure.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Alcoa is undervalued by 50.3%. Track this in your watchlist or portfolio, or discover 51 more high quality undervalued stocks.

Approach 2: Alcoa Price vs Earnings

For a profitable company, the P/E ratio is a practical way to think about value because it links what you pay for the stock to the earnings the business is currently generating. A higher P/E typically reflects higher expectations for future earnings growth or a perception of lower risk, while a lower P/E often points to more modest growth expectations or higher perceived risk.

Alcoa’s current P/E is 16.10x. This sits below both the Metals and Mining industry average P/E of 22.55x and the peer group average of 50.55x. This may initially make the stock look relatively inexpensive compared with those benchmarks.

Simply Wall St’s Fair Ratio for Alcoa is 22.21x. This is an estimate of what the P/E might be based on factors such as earnings growth profile, industry, profit margins, market cap and specific risks. This Fair Ratio can be more useful than a simple comparison with peers or the industry, because it adjusts for the company’s own characteristics rather than assuming all stocks should trade at similar multiples. Comparing the Fair Ratio of 22.21x with the current P/E of 16.10x indicates that the stock is trading below this implied fair level.

Result: UNDERVALUED

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

Fair value in this bullish narrative: US$73.87 per share.

Implied discount to this fair value: about 15.3% versus the recent price of US$62.64.

Revenue growth assumption: 5.67% a year.

• Analysts see Alcoa benefiting from decarbonization, tighter supply and low carbon products, which could support pricing and margins over time.
• The narrative builds around revenue growing in the mid single digits and profit margins moving higher, with earnings forecasts stretching out to 2029.
• To agree with this view, you would need to be comfortable with higher earnings, wider margins and a future P/E that is below the current industry level.

Fair value in this bearish narrative: US$46.37 per share.

Implied downside to this fair value: about 35.1% versus the recent price of US$62.64.

Revenue growth assumption: 0.2% a year.

• This view focuses on rising regulatory, environmental and tariff related costs that could pressure margins and keep earnings uneven.
• The narrative assumes flat revenue, lower profit margins over the next few years and earnings that sit well below current levels by 2029.
• To align with this case, you would need to expect limited top line progress, margin compression and a valuation multiple that stays relatively high against these earnings.
