Robert F. Hoffman, Century Aluminum Co's senior vice president of information technology and chief accounting officer, executed a sale of 10,529 shares of the company's common stock on March 11, 2026, according to a Form 4 filing with the Securities and Exchange Commission.
The shares were sold at prices ranging from $56.25 to $56.75, producing gross proceeds of $594,993. At the time of the sale, Century Aluminum's shares were trading near a 52-week high of $59.12, and the companys current market price of $54.73 was modestly below Hoffman's realized sale prices.
After the disposition, Hoffman retains direct ownership of 56,643 shares of Century Aluminum common stock, a total that includes unvested Restricted Stock Units. In addition to his direct holdings, he has an indirect interest of 14.5476 shares through a 401(k) plan vehicle.
The insider sale occurs within a broader corporate backdrop that includes recent operational and strategic developments for the aluminum producer. Century Aluminum reported fourth-quarter 2025 EBITDA of $171 million, a result positioned at the lower end of its prior guidance but still largely consistent with market expectations.
Analyst reactions have varied. BMO Capital Markets increased its price target for Century Aluminum shares to $61 from $52 while keeping an Outperform rating, citing potential upside tied in part to the planned restart of the Mt. Holly facility. Separately, Texas Capital Securities initiated coverage with a Buy rating and a $42 price target, implying a different view on valuation and upside potential.
On the corporate development front, Century Aluminum and Emirates Global Aluminium announced a joint venture to construct the first new primary aluminum plant in the United States since 1980. The planned facility, to be sited in Inola, Oklahoma, is expected to have capacity to produce 750,000 tonnes of aluminum per year. Under the announced ownership split, Emirates Global Aluminium will hold a 60 percent interest and Century Aluminum will hold the remaining 40 percent.
Market sensitivity is evident as well. Century Aluminum's share price moved lower after reports that the Trump administration was considering reductions to tariffs on steel and aluminum products. That news, combined with the company's earnings that were at the low end of guidance, contributes to a mixed near-term picture for the stock and for market participants assessing exposure to aluminum and related commodity markets.
Investment research available through third-party services notes that, despite the strong rally that left the stock up roughly 174 percent over the prior 12 months, some analysis still regards Century Aluminum as undervalued at prevailing prices.
