Vestas Shares Jump 18% at Open After Quarterly Report and Raised Guidance

Shares in Vestas rose 18% at the market open on Wednesday, August 12, 2026, after the Danish wind turbine maker published its quarterly report that morning alongside an upgrade to its forecast.

Half an hour after the opening bell, the stock was approaching a price of 210, an 18% gain against the previous day's close.

Investors were, by the account of the reporting, decidedly satisfied with the quarterly accounts Vestas released on Wednesday morning. The company paired the results with a raised outlook, a combination that fed the move.

The reaction was not confined to a single listing. Vestas was also set for a solid lift from the start elsewhere in Europe, on the back of the strong report and the guidance upgrade, according to energy-supply.dk.

A single-session move of that size is the kind of repricing that follows a guidance change rather than a routine earnings beat. Forecast upgrades reset the profit path investors are discounting for the rest of the year, which is why the market took the stock to a level near 210 within thirty minutes of trading.

For a listed turbine manufacturer, the sequence matters to the wider wind supply chain: order intake, pricing, and margin guidance from the largest listed players are among the few public, dated data points on demand for onshore and offshore turbine capacity. A guidance upgrade delivered with the quarterly report is a harder signal than commentary alone, because it carries a formal revision of the company's own projections.
