UBS Trims Wienerberger Stake to 3.83% as Brickmaker Prepares Strategy Update

UBS Group AG has disclosed a total voting position of 3.83% in Wienerberger, down from the 4.20% it previously reported. The new filing, published today, marks a step below the 4% mark for the Swiss bank's holding in the Vienna-listed brickmaker.

The headline decline in the aggregate position conceals a shift in its composition. Voting rights held directly through shares rose to 1.05% from 0.55%, while the portion attributed to financial instruments fell to 2.79% from 3.65%. Because the two components moved in opposite directions, the filing offers no clear signal of an outright share sale or of how UBS views the company.

The prior disclosure was dated 23 October and referenced a threshold-touch date of 21 October. Both the overall position and the separately reported share and instrument components are relevant to the latest change.

Nine-Month Figures and Efficiency Drive on the Calendar

Investor attention is now fixed on 12 November, when Wienerberger will publish results for the first nine months of 2026 and hold a conference call at 12:00 CET. The company has said the same date will bring an update on its strategic review and on accelerated cost-optimisation measures.

That update carries weight given the guidance cut already announced in the trading update. Wienerberger trimmed its 2026 operating EBITDA forecast to €640–650 million, citing weaker-than-expected seasonal construction activity and persistent cost inflation. The company also projected revenue of €1.2–1.3 billion and operating EBITDA of €170–180 million; both figures are expectations rather than reported results.

Separately, Wienerberger has confirmed it will take part in the BNP Paribas Exane MidCap CEO Conference in Paris on 17 November.
