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.
