Kansai Electric: nuclear restarts, fuel storage progress, rate hike, billing overcharge

Nuclear fuel storage advances Fukui's governor gave prior approval for an on-site dry storage facility for spent nuclear fuel, and Kansai Electric signaled it will join the Mutsu interim storage site. Both secure places to put used fuel, supporting continued nuclear generation, a low-cost power source that lifts profit.
Removes a key regulatory and fuel-disposal hurdle for running nuclear plants, a core earnings driver.
Corporate rate hike Kansai Electric will raise corporate electricity rates 10–15% from November, its first such increase in 11.5 years, to cover soaring repair costs. This supports revenue but may push some business customers to cut usage or switch suppliers.
Directly changes the price Kansai Electric charges its largest customer group, affecting revenue and competitiveness.
Billing overcharge scandal Kansai Electric overcharged about 4.92 million contracts, mostly households, since April 2024, totaling roughly 14 million yen, and submitted a fix plan to regulators. Refunds and added scrutiny are a reputational and regulatory drag, though the money involved is small.
A regulatory and trust issue that can weigh on the stock even if the financial amount is minor.
Mihama No. 3 leak and restart A water leak forced Kansai Electric to shut the Mihama No. 3 reactor in September, cutting generation, but it restarted on October 10 with commercial operation due November 4. The quick fix limits the earnings hit, though it highlights maintenance risk.
Shows both the outage risk and the recovery of a nuclear unit, which matters for low-cost supply.

Prysmian buys Atkore, wins Amazon data-center cable deal

Prysmian to buy Atkore for $3.8bn Prysmian agreed to buy US cable maker Atkore for $3.8 billion in cash, a 30% premium. It expands Prysmian's North American electrification and data-centre business, letting it sell more products to the same customers. Bigger scale and cross-selling can lift future earnings, though the cash outlay and debt taken on are the cost.
The acquisition is the period's biggest company-specific event and directly changes Prysmian's growth outlook.
Amazon Ohio data-centre cable supply deal Prysmian will make low-carbon aluminium cables for an Amazon data centre in Ohio, using Rio Tinto metal, at its Sedalia plant. It shows Prysmian winning work in the fast-growing data-centre power market and supports its green-revenue goal. No contract value was given and the technology is early-stage, so near-term earnings impact is limited.
It is a fresh, concrete win in Prysmian's key growth market of data-centre electrification.
AI infrastructure demand keeps Prysmian in favour Investors are rewarding companies that supply the AI build-out, and Prysmian was named among outperformers on strong AI-enabling demand. Data centres and power grids need huge amounts of cable, so this trend supports Prysmian's orders and pricing. It is a broad market tailwind rather than a company announcement.
It explains the sector-wide demand force behind Prysmian's share-price support this period.
Lawyer probe into Atkore deal fairness A shareholder-rights law firm is investigating whether Atkore's $95-per-share sale to Prysmian is fair to Atkore holders. Such probes are common and rarely block deals, but they can delay closing or push for better terms. For Prysmian the risk is mainly timing and cost, not a change to its strategy.
It is the main counterweight to the acquisition news and could affect deal completion.
