Private foundations Androsch and Dörflinger are selling a combined 567,000 shares in AT&S, the Austrian printed circuit board manufacturer, in a transaction valued at approximately €120 million.
The sale represents a significant reduction in holdings by the two entities, which have benefited from the recent surge in the company's share price.
The move introduces notable selling pressure into the market for AT&S shares.
While the foundations are realizing gains from the stock's performance, the volume of shares being offered could weigh on the stock's near-term momentum.
Investors will be monitoring whether the market absorbs the supply without significant price disruption.
AT&S, based in Styria, has seen its valuation rise in recent months, driven by strong demand in the electronics sector.
