Q1 earnings and buyback completion put Mueller Industries in focus

Mueller Industries (MLI) is back on investors’ radar after first quarter 2026 results showed higher sales, net income, and earnings per share compared with a year earlier, alongside the completion of a long running share repurchase program.

The earnings beat and completion of a long running buyback have come after a 1 month share price return of 18.18% and a 1 year total shareholder return of 76.05%. This suggests momentum has recently picked up from an already strong multi year base.

If this kind of move has you thinking about other industrial and materials opportunities, it could be a useful moment to scan 8 top copper producer stocks.

With the shares up 76.05% over 1 year and trading at a discount of around 14% to the latest analyst price target, the key question is whether Mueller Industries is still mispriced or if the market is already banking on more growth.

Preferred P/E of 17.1x: Is it justified?

On a P/E of 17.1x at a last close of $130.85, Mueller Industries screens as relatively inexpensive compared with both the broader US market and machinery peers, despite its recent share price strength.

The P/E ratio compares the current share price with earnings per share, so it captures how much investors are paying for each dollar of current earnings. For a business with established profitability, like Mueller Industries, it is a common way to gauge how the market is weighing its earnings track record, quality and outlook.

Here, the stock trades on a P/E of 17.1x versus 19.4x for the US market and 27.5x for the US Machinery industry, and it also sits below an estimated fair P/E of 24.8x. That highlights a valuation gap relative to these reference points.

Result: Price-to-earnings of 17.1x (UNDERVALUED).

However, investors still need to weigh exposure to cyclical copper and metals demand, as well as the risk that current valuation metrics already reflect optimistic expectations.

Another view from the SWS DCF model

While the P/E of 17.1x hints at a possible opportunity, the SWS DCF model paints a different picture. On this framework, Mueller Industries is valued at $108.61 per share, below the current $130.85. This points to an overvalued stock rather than a cheap one. Which lens do you trust more when the signals conflict?
