Listing standards are set out in the Vienna Stock Exchange Rules; Austrian Stock Exchange Act.

Wiener Börse at a glance:

One of the oldest continuously operating exchanges in the world. A focused index with significant concentration in banking, insurance, oil and gas, and infrastructure. The Austrian disclosure regime carries a distinctive step structure that differs from most EU peers.

On the Wiener Börse, blocks are negotiated off the central order book and printed under the MiFID II regime that governs EU venues: size above the large-in-scale threshold can carry deferred publication before it is reported through the exchange’s post-trade facility. Because the ATX is concentrated, a block’s size is read against the turnover of a relatively short list of liquid names — the banks, insurers and oil-and-gas majors absorb size that a Standard or Direct Market line could not. Any resulting move through a 4% (or 3%) voting-rights step is separately notifiable to the company, the exchange and the FMA. Settlement is T+2.

The principal regulatory reference on Wiener Börse is Stock Exchange Act Section 130. How it applies to any single transaction — reporting levels, step thresholds — turns on the underlying rules and national-law overlays, which we map against your contemplated transaction at the structuring stage alongside the counsel you appoint.
