Morgan Stanley Slashes Aurubis Rating Amidst High Valuation and Limited Growth Prospects

Morgan Stanley has taken a more cautious stance on Aurubis AG (XETRA: NAFG), downgrading the stock from "equal-weight" to "underweight." The firm's new price target is €95, down slightly from €98, implying about a 13% drop from Aurubis's recent close near €107.70 on October 16.

This shift arrives after Aurubis's shares surged roughly 50% since January, pushing its valuation to an all-time high of 8.8 times enterprise value to next twelve months' EBITDA. Morgan Stanley flagged this as a stretched multiple, particularly since Aurubis's earnings forecasts have remained mostly unchanged, contrasting with a 22% average EBITDA upgrade across the broader copper sector.

The bank highlighted a murky outlook for fiscal 2025-26. Positive influences like higher prices for gold, silver, and copper, plus record cathode premiums, are being offset by several headwinds: hedging losses, declining scrap refining and treatment charges, and currency pressures. This mixed bag creates a challenging growth environment for Aurubis.

Aurubis's diversified business model screens it somewhat from pure commodity swings, but that same diversity might also cap upside potential from metal price gains. The company's heavy investment in recycling-over 80% of its €1.7 billion capital expenditure target between 2021 and 2027-is viewed skeptically. Morgan Stanley labeled it a "show-me story" due to execution risks, especially around the Richmond project in the U.S., which is expected to contribute around 65% of the projected €260 million EBITDA boost.

Profitability assumptions for this project caught the analysts' attention. Per tonne earnings estimates for Richmond are roughly 3.5 times higher than Aurubis's current European recycling margins. Yet, full benefits may only materialize in fiscal years 2028-29, adding a longer timeline risk.

Though Aurubis's shares have gained from rising commodity prices, hopeful industrial stimulus in Germany, and heightened attention to cash flow, Morgan Stanley believes these factors are already faded into the stock price. They also expect Aurubis's return on capital employed to lag behind its peers over the next four years.

Notably, Morgan Stanley pointed to Poland's KGHM (WSE: KGH) as more compelling within the sector. With greater exposure to copper and precious metals and trading at a leaner 5.4x 2026 EV/EBITDA multiple-a 35% discount to peers-KGHM stands out as a comparatively cheaper play with stronger commodity ties.

Morgan Stanley's downgrade underscores the tension between lofty valuations and muddled earnings visibility for Aurubis. It also raises questions about the sustainability of recent gains in a sector where fundamentals are shifting, and growth is no longer guaranteed. Will Aurubis manage to execute its ambitious projects and justify its premium, or is the recent rally running out of puff?
