Hudbay Minerals (TSX:HBM) Stock May Be 19% Undervalued As Constancia Permit Expands

Listen to the news

After a very large 332.8% return over the past three years, Hudbay Minerals now sits at a point where its recent rally, a mixed overall value score, and an intrinsic value estimate from a Discounted Cash Flow (DCF) model suggesting the stock trades below that estimate all pull in slightly different directions.

  • Hudbay Minerals has delivered a very large 332.8% return over three years, which puts extra focus on whether the current share price still leaves room for further upside.
  • The recent approval to increase mill throughput at the Constancia mine in Peru can support expectations for sustained copper output. At the same time, execution and regulatory risks around expanding production remain important for how investors price the stock.
  • With a value score of 4 out of 6, Hudbay Minerals screens as a mixed picture rather than a clear bargain or clear overvaluation on the broader checks.

The stock's next move may depend on whether the current price already reflects the intrinsic value signalled by the Discounted Cash Flow (DCF) estimate or still leaves a margin between market price and that intrinsic value.

Hudbay Minerals delivered 107.7% returns over the last year. See how this stacks up to the rest of the Metals and Mining industry.

Is Hudbay Minerals Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) method estimates what Hudbay Minerals could be worth based on the cash it is expected to generate for shareholders. The model uses latest twelve-month free cash flow of about $358.8 million and assumes cash flows grow from current levels before settling into a steadier pattern, which fits a company with producing assets and defined expansion projects. On that basis, the DCF indicates an intrinsic value of around CA$37.65 per share.

Compared with the current share price, this implies the stock screens about 18.9% undervalued on a cash flow basis. Because the recent approval to increase mill throughput at the Constancia mine raises the potential for sustained copper output, it helps explain why investors are paying closer attention to whether Hudbay Minerals’ share price still sits below this intrinsic value estimate. Overall, the DCF workup indicates that, under the assumptions used, Hudbay Minerals appears undervalued relative to the cash flows currently built into the model.

Our Discounted Cash Flow (DCF) analysis suggests Hudbay Minerals is undervalued by 18.9%. Track this in your watchlist or portfolio, or discover 6 more high quality undervalued stocks.

Does Hudbay Minerals Look Fairly Valued on Earnings?

P/E is one of the clearest ways to compare Hudbay Minerals with other copper and mining stocks because it links the current share price directly to reported earnings. Hudbay Minerals trades on a P/E of about 13.0x, which sits slightly below the Metals and Mining industry average of roughly 14.5x and also below the broader peer group near 18.4x.

The fair P/E ratio for Hudbay Minerals, based on factors such as its size, profitability profile and sector, is estimated at about 12.5x, which is very close to where the stock currently trades. That small gap suggests the market is pricing Hudbay Minerals at roughly the level implied by its earnings, with neither a clear discount nor a clear premium emerging from this single metric.

On the P/E multiple, Hudbay Minerals stock appears to be trading at a level that is roughly in line with what its earnings profile would suggest.

The Bottom Line

For Hudbay Minerals, the Discounted Cash Flow (DCF) work suggests the stock could be undervalued, while the P/E multiple points to pricing that is about right relative to peers. That gap mainly reflects how the intrinsic value model leans on future cash flows from current and planned projects, whereas the market multiple is more tightly linked to sentiment and where similar stocks trade today.

With broader checks painting a mixed picture, the key question is whether execution and regulatory risk on its major projects, especially Copper World and Constancia, are being overestimated or whether that apparent discount is simply the market pricing those risks correctly.
