Century Aluminum Bets Big on Smelter-Led Revival

Century Aluminum Co ((CENX)) has held its Q4 earnings call. Read on for the main highlights of the call.

Century Aluminum’s latest earnings call struck a notably upbeat tone despite lingering operational hiccups. Management highlighted a step‑change in strategy, stronger profitability and lower leverage, arguing that insurance coverage, rising aluminum prices and fresh cash from asset sales more than offset temporary outages, storms and energy spikes weighing on recent results.

Oklahoma Smelter JV Signals Transformational Growth

Century unveiled a 60/40 joint venture with Emirates Global Aluminium to build the first new U.S. smelter in almost 50 years, backed by a $500 million Department of Energy grant. Using EGA’s EX technology and a boosted 750,000‑ton capacity target, management said the project could more than double total U.S. primary aluminum output once operational.

Hawesville Sale Unlocks Cash and Equity Upside

The company closed the $200 million cash sale of its Hawesville site to TeraWulf and kept a 6.8% non‑dilutive equity stake in the planned AI and data‑center complex. Century sees that stake ultimately worth well above the cash proceeds and holds a put option to exit after the first year of operations, giving it both upside and a defined liquidity path.

Accelerated Restarts Boost 2026 Volume Story

Repairs at Grundartangi’s Line 2 are progressing faster than expected, with a restart now targeted by late April and near full smelter output by July. Mt. Holly’s restart is slated to begin in April and finish by late June, supporting guidance for 2026 shipments around 630,000 tons and potential annualized capacity nearer 750,000 tons when all projects ramp.

Earnings Rebound and Balance Sheet Improvement

Fourth‑quarter shipments were roughly 140,000 tons, with net sales of $634 million and adjusted EBITDA jumping to $171 million, a sequential gain of about 69%. Adjusted net income reached $128 million or $1.25 per share, operating cash flow was $170 million, cash ended at $134 million and net debt fell to $421 million, aided by tax credit inflows.

Pricing Tailwinds and Market Tightness

Aluminum prices have surged, with January hitting a four‑year high of $3,325 per ton and spot hovering near $3,100, while Q4 realized LME averaged $2,615. Regional premiums in the U.S. and Europe strengthened and management expects lagged Q1 LME pricing around $2,850 per ton, which could add roughly $70–$80 million to adjusted EBITDA before other offsets.

Disciplined Capital Plan and 2026 Targets

For 2026 Century projects shipments of about 630,000 tons, capital spending of $115–$125 million and lower cash interest costs. Roughly $45 million of that capex is earmarked to restart the final 90 pots at Mt. Holly, while management stressed a tight focus on high‑return projects such as Mt. Holly and Jamalco’s TG4 turbine to lift cash flow.

Operational Strength at Sebree and Jamalco

Sebree delivered a record year across key operational and profitability metrics despite challenging winter weather, underscoring what management called strong plant‑level execution. At Jamalco, teams prepared effectively for Hurricane Melissa, avoiding major damage, and the refinery is ramping back toward stable production with an on‑site TG4 turbine set to cut power costs.

Grundartangi Outage Weighs on Margins

A failure of three transformers forced a halt to potline 2 at Grundartangi, driving an estimated $40–$50 million margin loss in the quarter and creating near‑term cash strain. Replacement units are ordered and insurers have confirmed coverage, though reimbursements will lag by one to two quarters and full transformer installation will extend later into the year.

Hurricane Disruptions Lift Jamalco Power Costs

Hurricane Melissa triggered grid instability in Jamaica, pushing up Jamalco’s power prices and trimming volumes in November and December. Century expects a step‑down in energy costs once the TG4 turbine starts in April because the refinery will no longer depend on grid electricity, materially easing a key cost pressure point.

Energy Spike and Hedge Drag at Sebree

Winter storm “Fern” sent Indiana Hub power prices sharply higher for about two weeks, creating a roughly $20 million adjusted EBITDA headwind at Sebree and about $15 million in net cash impact. About a quarter of that exposure was hedged, but realized settlements will still produce a $10–$15 million cash drag in the first quarter, booked below adjusted EBITDA.

Rising Input Costs and Working Capital Build

The company flagged modest increases in key raw materials like coke, pitch and caustic soda, plus some operating cost pressure, which together may shave up to $10 million from Q1 earnings. A working capital build also hit late in the year as LME‑linked alumina purchases timed awkwardly, but management framed these as manageable rather than structural issues.

GAAP Earnings Masked by One‑offs

Despite robust adjusted results, GAAP net income for the quarter was just $1.8 million or $0.02 per share because of several exceptional items. These included share‑based compensation, unrealized derivative losses and business‑interruption and hurricane‑related costs, along with $18 million of withholding taxes tied to equity awards.

Liquidity Tightness from Timing Effects

Century ended the year with $134 million in cash, short of internal capital allocation goals due mainly to the lag between Grundartangi’s lost margin and expected insurance payouts. The $200 million Hawesville proceeds arrived only in February, illustrating how timing mismatches around outages, repairs and recoveries can temporarily pressure reported liquidity.

Guidance Highlights Strong Near‑Term Momentum

Management guided first‑quarter adjusted EBITDA to $215–$235 million, built on lagged LME pricing of $2,850 per ton and firmer regional premiums, even after hedge, energy and cost headwinds. For 2026 they reiterated shipment targets near 630,000 tons, capex of $115–$125 million, lower interest expense and meaningful insurance recoveries, pointing to higher volumes and cash flow as restarts annualize.

Century’s call painted a company at an inflection point, pairing cyclical pricing strength with structural growth and operational recovery. While outages, storms and power volatility still bite into earnings and liquidity, investors heard a message of improving fundamentals, expanding capacity and a more resilient portfolio that could support stronger performance into 2026 and beyond.
