Pierin Vincenz

The appeal hearing took place in August 2026. Prosecutors sought six years' imprisonment for Vincenz and Stocker; the defence teams requested acquittal and raised, among other points, limitation periods affecting certain charges. Vincenz reiterated that he never intended to harm Raiffeisen or Aduno. At the close of proceedings, the presiding judge said judgment would be delivered several weeks later.

Zurich District Court sentenced Vincenz to three years and nine months' imprisonment and a suspended financial penalty, finding him guilty, among other offences, of fraud, criminal mismanagement, passive private-sector bribery and expense-related offences. According to Reuters, he was also ordered to compensate companies approximately 1.6 million francs in total.

The criminal case concerned several transactions involving Commtrain, Eurokaution, GCL and Investnet. Prosecutors alleged that Vincenz and Stocker secretly acquired stakes and subsequently profited when Raiffeisen or Aduno purchased those companies, while holding decision-making or advisory positions.

At first instance, the trial established that Vincenz had obtained reimbursement from Raiffeisen for numerous expenses at cabarets and strip clubs, approaching 200,000 francs. He maintained that these visits largely involved maintaining business relationships; the court instead found that this interpretation of business expenses went too far.

The first-instance court also found wholly private or insufficiently business-related expenses: family or leisure trips, a 700-franc dinner with a woman met on Tinder described as a job interview, and the repair of a damaged hotel room. The court ordered, among other things, repayment of approximately 300,000 francs to Raiffeisen for improper expenses.

According to the 2022 first-instance judgment, Vincenz and Beat Stocker held an undisclosed stake in Commtrain before the company was acquired by Aduno, of which Vincenz chaired the board and Stocker was CEO. Prosecutors assessed the private gains shared from this transaction at several million francs.
