ATOSS Software (ISIN DE0005104400) reported that Klaus Bauer left its Supervisory Board effective September 30, 2026, as part of Chief Executive Officer Andreas Obereder's planned move to the Supervisory Board. The personnel change appeared in the company's nine-month release dated October 23, 2026, published by EQS News.

What changes in governance?

Bauer's departure also ended his tenure as chairman of the Audit Committee. ATOSS said the change is linked to the planned transition of Obereder from the Management Board to the Supervisory Board at the turn of the year, making the board transition a concrete governance step rather than a future calendar item.

The same release reported EUR 155.8 million in revenue for the first nine months of 2026, up 12 percent from EUR 139.3 million in the prior-year period. Cloud and Subscriptions revenue rose 26 percent to EUR 85.2 million, while the Cloud and Subscriptions order backlog increased 23 percent to EUR 125.0 million as of September 30, 2026.

How strong is the operating base?

ATOSS reported a 37 percent EBIT margin for the first nine months of 2026, compared with 35 percent a year earlier. Management raised its fiscal-year 2026 EBIT margin forecast to 37 percent, while expecting total revenue of EUR 210 million to EUR 215 million at the lower end of that range.

Three dated developments

On September 30, 2026, Klaus Bauer left the Supervisory Board. On October 23, 2026, ATOSS reported EUR 155.8 million in nine-month revenue and a 37 percent EBIT margin. On October 28, 2026, the stock stood at EUR 93.15 at Lang & Schwarz, below the previous Xetra close.

What comes next?

ATOSS is scheduled to appear at the German Equity Forum on November 23, 2026. The governance transition and the subscription backlog of EUR 125.0 million give investors two measurable reference points for the next company update.
