Denso profit miss and quake supply hit outweigh Micron deal

April–June profit falls 14%, full-year forecast misses estimates Denso's quarterly net profit dropped 14.4% to 67.8 billion yen as higher material costs and growth spending squeezed margins. Revenue rose on electrification and smart products, but the unchanged full-year profit forecast of 382 billion yen badly missed the 424.6 billion yen analysts expected. The earnings miss is the main reason the stock plunged on July 31.
This is the single biggest new company-specific event and directly explains the stock's sharp fall.
Kumamoto earthquake forces Toyota plant halts, Denso checks suppliers Toyota will stop its Tahara plant from August 3–7 and extend shutdowns at three Fukuoka plants after the Kumamoto earthquake damaged Aisin Kyushu's factory. Denso is investigating damage at its own suppliers. Multi-tier supply chains take time to assess, so production cuts at major customers threaten Denso's near-term sales and parts deliveries.
A fresh supply-chain disruption that can reduce Denso's production and revenue in coming weeks.
Micron multi-year AI memory deals include Denso as partner Micron completed long-term Strategic Customer Agreements with seven automotive suppliers, including Denso, securing advanced memory and storage for AI-enabled vehicles. For Denso, this locks in supply visibility and pricing certainty for key electronics, supporting its intelligent-product roadmap. The deals are a modest positive but not enough to offset the profit miss.
A new partnership that supports Denso's technology and supply outlook, though smaller than the earnings hit.

Cummins rides AI data-center power boom, but tariff hit and overbuild fears temper gains

AI data-center power demand drives record sales and raised guidance Cummins posted record Q2 sales of $9.5 billion, up 9%, and raised its 2026 revenue growth outlook to 10–13%, as AI data centers drove demand for its power equipment.
This is the core new positive force behind Cummins' stock this quarter.
Major data-center deals and capacity expansion Cummins signed a 2-gigawatt Circe Energy deal, a hyperscaler agreement, and its largest data-center battery storage order, while adding $450 million in generator capacity to double data-center sales to $9 billion by 2030.
These concrete wins and investments show how Cummins is capturing the AI power boom.
Dividend hike and bullish analyst targets Cummins raised its dividend by 10% and analysts lifted price targets as high as $901, reflecting confidence in its growth trajectory.
Shareholder returns and analyst optimism are new positive signals for the stock.
Earnings miss and overbuild/regulatory risks Adjusted EPS of $6.73 missed by 6.3% on tariffs and bonus costs; Bernstein warns of power-equipment overbuild, and EPA's 2027 emissions rule remains uncertain, tying Cummins to one fast-moving market.
These are the key counterweights that kept the stock from rising even more.

Cummins' AI power boom grows, but margin miss and overbuild risk temper it

Q2 profit miss on tariffs and pay costs Cummins beat on revenue but adjusted earnings per share of $6.73 missed by 6.3%, which the company blamed on tariffs and higher bonus costs. A profit miss makes investors question how much of the AI sales boom actually reaches the bottom line, weighing on the stock.
It is the main new negative and explains why the stock did not simply rise on record sales.
Analyst warns of power-equipment overbuild risk Bernstein says U.S. data center construction may reach only 35 gigawatts by 2030, below the 40 GW needed to justify planned generator capacity, with Cummins among the most exposed. If AI power demand grows slower than factories are built for, prices and orders could weaken.
It is the clearest new counterweight to the bullish AI-demand story.
Largest battery storage order for a data center Cummins will supply battery energy storage systems for a large U.S. data center, its biggest such deployment yet, to smooth AI-driven power swings. It shows Cummins can sell beyond diesel generators, widening its data center opportunity and supporting future sales.
It is a new contract that expands Cummins' addressable data center market.
Data center sales targeted to double by 2030 Cummins is investing $450 million more in generator production and expects data center-related sales to rise 80% to $9 billion by 2030, as AI racks need far more backup power. This confirms the growth runway, but also ties Cummins more tightly to one fast-moving market.
It quantifies the new growth plan and the concentration risk behind the stock's rise.

Cummins rides AI data-center power boom to record sales and higher guidance

AI data-center power demand drives record sales Cummins signed a 2-gigawatt supply deal with Circe Energy and a multi-year hyperscaler agreement, fueling record Q2 sales of $9.5 billion, up 9%. Power Systems revenue grew 19% year-over-year. This new demand source is the main reason the stock is rising.
This is the core new growth driver behind Cummins' re-rating and record results.
Raised guidance and dividend hike signal confidence Cummins lifted full-year 2026 revenue growth guidance to 10-13% and EBITDA margin to 18-18.5%, and raised its dividend 10% for the 17th straight year. Higher guidance tells investors the company expects the good times to continue.
Guidance and dividend increases directly boost investor confidence and the stock price.
Analysts raise price targets on power demand Analysts lifted Cummins' fair value estimate to $748.81 from $643.36, with targets up to $901, citing data center, truck, and infrastructure demand. Higher analyst targets often pull the stock price up as investors follow their lead.
Analyst upgrades reflect and reinforce the positive demand story, influencing price.
EPA emissions rule creates engine launch uncertainty Cummins will phase in its 2027 HELM engines under proposed EPA flexibility, but the final rule is uncertain and could change timelines. This regulatory risk could delay new products and weigh on future sales, though shares barely moved on the news.
This is the main counterweight—regulatory uncertainty that could disrupt Cummins' product transition.
