Nucor's Q3 Profit Miss and Oversupply Fears Offset Tariff Gains

  • Q2 Profit Nearly Doubled on Record Shipments Nucor's Q2 profit nearly doubled to $1.156 billion, with revenue up 23% on record shipments and higher prices. This showed the core business was strong heading into Q3.

    It highlights the strong underlying performance that supported the stock early in the period.

  • Tariffs Curbed Imports and Aided Domestic Steelmakers Section 232 enforcement and a new 25% tariff on Brazilian steel reduced foreign competition, helping domestic producers like Nucor keep prices and volumes higher.

    Tariff policy was a key external force that benefited Nucor during the quarter.

  • Q3 Guidance Missed Estimates, Shares Fell Over 3% Nucor guided Q3 earnings to $5.55–$5.65 per share, below analyst estimates of $6.00–$6.20. The miss sent shares down over 3% as investors worried about slowing momentum.

    This was the most direct negative catalyst for the stock during the period.

  • Oversupply Fears and Berkshire Stake Cut Weighed on Sentiment Berkshire Hathaway halved its stake, and a planned $15 billion Iowa mill raised concerns about future oversupply. Canada's retaliatory tariffs also hurt U.S. steel exports, adding to the negative mood.

    These factors increased uncertainty and pressured the stock despite tariff benefits.

Nucor's strong quarter offset by demand and oversupply worries

  • Q2 earnings beat and dividend affirmed Nucor's Q2 profit and revenue beat expectations, and the dividend was affirmed. Analysts see the stock about 4% undervalued and have raised earnings estimates ahead of the October 26 report.

    This shows the core business is performing well and supports the stock.

  • Berkshire Hathaway halves stake Berkshire Hathaway cut its Nucor stake in half, a negative signal that may worry other investors and weigh on the shares.

    This is a notable negative event that pressured the stock during the period.

  • US-Canada tariff talks collapse, 50% tariffs return A tentative US-Canada deal to halve steel tariffs briefly pressured shares, but talks collapsed and 50% tariffs returned. The uncertainty added to market jitters.

    This trade policy uncertainty affected Nucor's stock during the period.

  • Planned $15 billion Iowa mill raises oversupply fears A planned $15 billion Iowa mill (Mesabi Metallics, production by 2030) raised concerns about a future steel glut, pressuring steel stocks including Nucor.

    This new supply threat weighed on the stock and the sector.

Nucor's profit rebound and tariff edge offset by new steel supply

  • Profit rebound and dividend support Nucor beat second-quarter earnings and revenue expectations, affirmed its dividend, and analysts see the stock about 4% undervalued. The company reinvested $860 million in growth projects. This supports the stock by showing the business is generating strong profits and returning cash to shareholders.

    It shows the fundamental profit recovery that is pushing NUE up.

  • Tariffs reduce import competition Diamond Hill Capital said Nucor benefited from reduced import competition and supportive trade policy, which strengthened pricing power for domestic steel producers. Solid shipment volumes also helped earnings. This pushes NUE up because less foreign competition lets Nucor charge more for its steel.

    It explains a key external force behind Nucor's pricing power and stock gains.

  • New $15 billion steel mill adds supply A planned $15 billion steel mill in Iowa by Mesabi Metallics could start production by 2030. Steel stocks, including Nucor, fell on worries that this new domestic capacity will worsen the supply-demand balance. More steel supply can pressure prices and hurt Nucor's profits.

    It is a new competitive threat that directly weighs on Nucor's future pricing and stock.

  • Analysts raise estimates ahead of earnings Analysts lifted Nucor's earnings estimates ahead of its October 26 report, with consensus EPS up 5.22% over the past month. The stock rose 1.7% on the day. Rising estimates signal growing confidence in Nucor's profit outlook, which supports the share price.

    It shows forward-looking optimism that is currently driving the stock higher.

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.

Q2 2026

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.

ArcelorMittal Q3: AI deals, buybacks, policy wins offset Ukraine and profit setbacks

  • AI and tech partnerships ArcelorMittal partnered with AWS and Microsoft to use artificial intelligence in steelmaking, aiming to cut costs and improve efficiency. An Amazon deal to supply low-carbon XCarb steel also opened a new sales channel.

    These partnerships are new this quarter and signal innovation and demand for greener steel, supporting the stock.

  • Capital returns and policy tailwinds Rising EBITDA and share buybacks returned cash to shareholders. Tighter EU import quotas and efforts to ease carbon rules helped European steel prices, while a UBS upgrade boosted sentiment.

    These factors directly improve profitability and investor confidence, driving the stock higher.

  • Brazil expansion for higher-margin steel The Pecém expansion in Brazil is designed to produce higher-margin steel, improving the company's product mix and profitability. This strategic move supports long-term growth.

    It is a new initiative this quarter that enhances future earnings potential.

  • Ukraine war disruption and profit weakness Missile and drone strikes halted output at Kryvyi Rih, killing or injuring workers. Q2 net profit fell sharply, and the Italy JV exit ceded upside to a rival, raising strategy doubts.

    These are major operational and financial setbacks that weigh on the stock and offset positive developments.

Buybacks, EU import quotas and UBS upgrade lift ArcelorMittal

  • Buyback shrinks share count ArcelorMittal finished buying back 10 million shares and immediately started a second 10 million share tranche, cancelling the stock. Fewer shares means each remaining share owns more of the company's profit, which supports the share price over time.

    A concrete capital return that directly lifts per-share value.

  • EU quotas tighten steel supply New EU safeguards cap duty-free steel imports at 18.3 million tonnes a year, with a 50% tariff above that, removing about 9 million tonnes of imports. Less foreign steel should raise European prices, and UBS says every €10 per tonne adds roughly $325M to ArcelorMittal's earnings.

    The main structural force behind higher European steel prices and profits.

  • UBS upgrade on oversold shares UBS upgraded ArcelorMittal to Buy with a €71 target, up from €61, saying shares fell nearly 20% in a month and are oversold. It expects an EU steel price rally and sees ArcelorMittal as the most liquid way to play European steel; the stock rose 4.6%.

    A major broker re-rating that names the specific upside case.

  • Italy JV exit cedes upside ArcelorMittal walked away from buying the remaining 51% of its Italian joint venture after Rome imposed conditions limiting job and structural cuts. It avoids extra spending and regulatory risk, but hands potential upside to rival Acciaieria Arvedi and raises doubts about its Italian strategy.

    The clearest counterweight: a lost growth opportunity and strategic setback.

ArcelorMittal: Ukraine strikes halt output, Brazil expansion and AI push offset

  • 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.

    A concrete growth investment that improves the long-term earnings mix.

  • Microsoft Azure and AI deal to cut costs over time ArcelorMittal expanded its Microsoft partnership, making Azure its main cloud platform and embedding AI and data tools across its IT systems. The goal is lower legacy IT costs and better efficiency, a slow-building positive for margins and the stock.

    A structural efficiency driver that supports profitability beyond daily price moves.

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. Amazon will also buy lower-carbon XCarb steel for years, giving a steady new customer. Both support future profits and the share price.

    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. If Brussels listens, it lowers a big cost burden. The EU is now reviewing the system, so this is a live positive for the stock.

    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. The company expects higher shipments ahead and sees $1.8 billion more EBITDA from projects. The headline profit fall may worry some, but the operating trend is improving.

    Latest earnings show a mixed picture that investors are weighing right now.
