Prysmian Shares Surge 150% in 12 Months as Global Power Grid Rebuild Fills Order Books

The Quick Take

• Prysmian shares gained 150% over 12 months as global power grid investment fills order books to capacity
• Governments worldwide pouring billions into electricity infrastructure is translating directly into Prysmian revenue
• Corning — another infrastructure-adjacent AI play — also achieved a similar multi-month share price surge

Prysmian, the Italian cable and wire manufacturer, achieved a 150% share price gain over twelve months, driven by accelerating global investment in power grid infrastructure. Governments across Europe, North America, and Asia are channeling billions into grid modernization, renewable energy interconnects, and offshore wind cabling — all of which directly populate Prysmian's order backlog. The company has positioned itself as an indispensable supplier to the energy transition, and the scale of infrastructure spending is creating visible backlog visibility that equity markets are rewarding with a structural re-rating well beyond typical cyclical multiples.

Prysmian's 150% gain positions it alongside AI-infrastructure adjacent plays like Corning, which also surged over twelve months by reinventing itself as a supplier of fiber and data center cabling critical to AI buildout. The common thread is infrastructure scarcity: both companies benefit from bottlenecks in physical infrastructure that software cannot replace. For Prysmian's cable competitors — Nexans (France), Southwire, and niche offshore-cable specialists — the price re-rating of the category raises the bar for investor expectations and may accelerate consolidation as smaller players seek premium valuations. European utilities and grid operators face higher capex costs as cable supplier pricing power grows.

Watch Prysmian's order book updates and revenue guidance for confirmation that the backlog translates into earnings — a company trading at re-rated multiples after 150% appreciation needs consistent guidance beats to sustain the valuation. European and US grid investment program timelines are the macro variable: any legislative delays to grid modernization budgets (EU Green Deal, US IRA grid component) would create air pockets in Prysmian's forward revenue visibility. Nexans quarterly results provide the clearest peer comparison — if Nexans similarly reports strong order momentum, it validates the sector thesis; if Nexans disappoints, it raises questions about whether Prysmian's gains are sustainable or have overshot.
