Nucor's Profit Doubles but Guidance Misses, Tariff Risks Mount

Q2 Profit Nearly Doubles on Record Shipments Nucor's Q2 profit jumped to $1.156 billion, with revenue up 23% and record shipments of 7.1 million tons. Strong pricing and volumes drove the gains, showing robust demand for its steel.
This is the core positive event that drove Nucor's financial performance in the period.
Tariff Enforcement and New Tariffs Support Pricing Aggressive enforcement of Section 232 tariffs cut finished steel imports from 23% to 16%, and a new 25% tariff on Brazilian steel further reduced foreign competition. This helped keep domestic steel prices high.
Tariff actions directly influenced Nucor's pricing power and competitive position.
Q3 Guidance Misses Expectations, Shares Fall Nucor guided Q3 earnings to $5.55–$5.65 per share, below the $6.00–$6.20 consensus. The miss sent shares down over 3%, signaling that profit growth may be slowing.
This was a key negative event that directly impacted investor sentiment and the stock price.
Berkshire Hathaway Halves Stake and Canada Tariffs Hit Berkshire Hathaway cut its Nucor stake in half, and Canada imposed retaliatory tariffs of 15%–50% on U.S. steel exports. These developments raised concerns about demand and investor confidence.
These events added significant negative pressure on Nucor's stock and outlook.

Nucor's Q3 Profit Miss Overshadows Tariff Gains

Q3 guidance falls short of Wall Street Nucor said Q3 profit will be $5.55-$5.65 a share, below the roughly $6.00-$6.20 analysts expected. Higher product costs and weaker raw materials results offset firm steel prices. The stock fell over 3% after hours, as investors worry near-term earnings are less strong than hoped.
This is the main new event of the period and directly explains why NUE moved down.
Canada's retaliatory tariffs hit U.S. steel exports Canada's counter-tariffs took effect September 8, putting 15%-50% duties on about C$27.6 billion of U.S. goods, including steel. That makes Nucor's exports to Canada more expensive and can reduce sales there, a direct drag on results.
A new trade action that directly affects Nucor's export demand and pricing.
Long-term growth plans carry execution risk Nucor's own plan targets $40.5 billion revenue and $4.5 billion earnings by 2029, but that requires big capacity investments to pay off. The Q3 miss sharpens focus on whether demand and pricing can support those projects, a risk that could cap the stock.
Adds the real counterweight: future growth depends on execution and demand holding up.

Tariff Rollercoaster and Berkshire Cut Pressure Nucor

Berkshire halves Nucor stake Berkshire Hathaway roughly halved its Nucor stake in Q2, a negative signal from a famous value investor. It may pressure the stock as some investors follow Berkshire's moves, though it doesn't change Nucor's actual business.
This is a new, high-impact capital event that can weigh on NUE's price.
US-Canada tariff cut plan hits steel stocks A tentative US-Canada deal would halve tariffs on Canadian steel and aluminum from 50% to 25%, increasing import competition. Nucor and peers fell 2.6% to 7.5% on the news, as lower tariffs mean foreign steel can undercut domestic prices.
This new tariff development directly threatens Nucor's pricing power and stock.
US-Canada talks collapse, 50% tariffs back on Trade talks between the US and Canada collapsed, paving the way for 50% tariffs on Canadian imports. US steel stocks rose, with analysts saying Nucor stands to benefit most, as higher tariffs keep cheaper Canadian steel out.
This new reversal restores tariff protection, a positive for Nucor's pricing and sales.
Nucor shares fall 6.8% since earnings beat Despite a Q2 earnings beat, Nucor shares have dropped 6.8%, underperforming the S&P 500. The market may be looking past strong results to worries about future tariffs and demand, showing that good news alone isn't lifting the stock.
This new article highlights the stock's recent weakness and investor concerns.

Nucor's Profit Nearly Doubles as Tariffs Curb Steel Imports

Q2 profit nearly doubles, revenue up 23% Nucor earned $1.156 billion ($5.04/share) in Q2, up from $603 million a year ago, with revenue up 23% to $10.4 billion. Record steel shipments of 7.1 million tons and higher selling prices show the core business is strong, supporting the stock.
The earnings beat is the main new fundamental driver of NUE's price this period.
CEO credits Trump tariffs for strong quarter CEO Topalian said aggressive enforcement of Section 232 tariffs is cutting unfairly traded imports, helping Nucor. Finished steel import share fell from 23% to 16%, leaving more room for domestic producers. This policy support is a key reason profits jumped.
Tariff enforcement is the central force behind Nucor's profit surge and stock rally.
New 25% tariff on Brazilian steel imports The U.S. imposed a 25% Section 301 tariff on many Brazilian goods, including steel. This makes foreign steel costlier, so buyers may shift to Nucor's domestic product. It adds to existing tariffs that already protect U.S. steelmakers.
A fresh tariff action directly reduces import competition for Nucor.
JFE partnership targets high-grade steel demand JFE Holdings said its U.S. joint ventures with Nucor focus on high-grade steel like electrical and automotive sheets. JFE sees motorization and electrification as growth drivers. This signals steady demand for Nucor's more profitable specialty products.
It shows a partner expects strong demand in Nucor's high-value product lines.

Nucor's Profit Outlook Jumps on Higher Steel Prices and Solid Demand

Q2 Earnings Guidance Beats Expectations Nucor expects Q2 earnings of $4.70–$4.80 per share, well above the $4.21 consensus and last year's $2.60. Higher steel prices, steady sales volumes, and $130 million in raw material refunds are driving the increase, signaling strong profitability ahead.
This is the main new event that directly boosts investor confidence in Nucor's near-term profits.
Steel Prices Surge Above $1,100 per Ton Hot-rolled coil steel prices have climbed above $1,100 per ton, helped by tight supply, fewer imports due to tariffs, and firm demand. As a major producer, Nucor earns more per ton sold, which lifts its revenue and margins.
Higher steel prices are a key force behind Nucor's improved earnings and stock performance.
Strong Demand from Construction, Infrastructure, and AI Data Centers Nucor benefits from healthy demand in non-residential construction, infrastructure, military, and energy. AI data centers are a new source of steel demand, with 831 projects under construction globally. This supports sales volumes and pricing.
Demand strength is a fundamental driver of Nucor's revenue and earnings growth.
Analyst Warns Steel Rally May Be Peaking Morgan Stanley kept Nucor at Equal-weight, saying the steel price rally is near its peak and prices could fall in 2027–2028 as new supply and imports rise. This is a caution that future gains may be limited, even as current profits stay strong.
It provides a balanced view, highlighting a potential headwind that could cap Nucor's stock upside.

Second missile strike halts Kryvyi Rih steel output A ballistic missile hit ArcelorMittal's Kryvyi Rih plant in Ukraine, killing two contractors and stopping primary steel production while ironmaking complex #1 is assessed. This is the second strike in five weeks, so lost output and repair costs weigh on earnings and the share price.
Directly hits production and earnings, the clearest negative force on MT.AS this period.
Earlier drone attack injured workers at same plant In mid-August a large Russian drone and missile attack on Kryvyi Rih injured 13 ArcelorMittal employees and killed one. It showed the war is repeatedly disrupting the company's Ukrainian assets, adding risk and cost that pressure the stock.
First of the two strikes; sets up the recurring war risk to ArcelorMittal's assets.
Brazil Pecém mill expansion targets higher-margin steel ArcelorMittal aims to decide by year-end on a $961M expansion of its Pecém mill in Brazil, adding a 1.5M-ton hot-rolled coil line. Turning cheap slab into higher-value rolled steel should lift future profits, supporting the share price.

ArcelorMittal: AI deal, ETS relief push, mixed Q2 profit

AI partnership and Amazon steel supply deal ArcelorMittal is teaming with Amazon Web Services to use AI across its steelmaking, which should cut costs and lift efficiency.

New technology and demand news that directly boosts ArcelorMittal's earnings outlook.
Steelmakers push for softer EU carbon rules ArcelorMittal and two peers asked the EU to pause rising carbon-permit costs until cheap power, hydrogen and carbon capture are ready.

Regulatory relief would directly cut ArcelorMittal's costs and improve margins.
Q2 profit falls but underlying earnings rise Net profit dropped to $683 million from $1.79 billion a year ago, yet EBITDA rose to $2.06 billion and sales grew.
