Century Aluminum (CENX): Assessing Valuation After New Tariffs and Mt. Holly Restart Potential

Simply Wall St·09/17/2025 18:47:57
Listen to the news

Century Aluminum (CENX) just gave investors a lot to think about. The company’s shares jumped 6.4% in the last session, fueled by a spike in trading volume after news of fresh 50% tariffs on aluminum imports. With U.S. prices poised to climb, Century Aluminum stands to benefit, especially as it restarts the Mt. Holly smelter at full production and bolsters its financial position with a $395 million debt financing package. All these moves could reshape its growth prospects and earnings potential in the months ahead.

Stepping back, it has already been a standout year for Century Aluminum. Since the start of the year, the stock has surged over 45% and is up nearly 80% over the past twelve months. Recent initiatives, like restarting operations in South Carolina and securing new funding, suggest momentum is building as the company capitalizes on favorable regulatory and market shifts.

But with the stock riding high, how much upside is left? Is the market accurately valuing future growth, or does Century Aluminum present a rare buying opportunity at this stage?

Most Popular Narrative: 3.5% Undervalued

According to the most widely followed narrative, Century Aluminum is currently trading at a slight discount to its fair value. Analysts see upside potential based on robust future growth projections and improved profitability.

The expansion and restart of Mt. Holly, along with progress on a new U.S. smelter, positions Century Aluminum to meaningfully increase U.S. primary aluminum production. This enables the company to capture rising domestic demand driven by reshoring of supply chains and incentivized by government tariffs and trade protections. These factors support future revenue growth and improved fixed cost absorption, thus enhancing net margins.

Think accelerating revenues, expanding margins, and a profit forecast that turns heads. Which critical figures are propelling this premium? Unlock the details and see how the numbers stack up against market expectations.

Result: Fair Value of $27.00 (UNDERVALUED)
